Background: Clinical outcomes of patients presenting with STEMI are significantly improved by reducing time from vessel occlusion to coronary blood flow restoration. In an effort to improve outcomes, we developed a secure mobile application, STEMIcathAID, and designed a pilot project implementing the app into the workflow for STEMI patients transfer. The aim of the study is to assess the impact of the app on key metrics for STEMI transfer before (historic) and after app launch., Methods: The pilot project included physicians, nurses and technicians from the Emergency Medicine and Nursing Departments at the referring center, the catheterization laboratory and transfer center. From July 2021 to February 2023, the referring center activated STEMIcathAID alarms in parallel with the previously established STEMI activation with traditional phone call to transfer center., Results: One hundred eleven suspected STEMI calls were activated through the app with 66 accepted and 45 rejected cases; thirty-one STEMI cases with available device time were compared with 42 STEMIs activated through the traditional pathway before the app implementation. Median door-to-device time for STEMIcathAID-assisted transfer decreased from 106 to 86 min (p < 0.001). The significant improvement, 20 min (19%), of the key metric for interhospital transfer resulted in all STEMI cases meeting the AHA goal of door-to-device time ≤ 120 min. In addition, median door-in-door-out time at the referral hospital decreased from 56 to 50 min (p = 0.01)., Conclusions: Implementation of a mobile app into STEMI workflow of a large urban healthcare system significantly improved the quality of care for transfer of STEMI patients., Trial Registration: AHA Get With The Guidelines-Coronary Artery Disease® (GWTG-CAD) registry is a national quality improvement program and is not subject to the institutional review board approval., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024 The Authors.

Background: Atherosclerosis in more than 1 vs. 1 arterial bed is associated with increased risk for major adverse cardiovascular events (MACE). This study aimed to determine whether the risk of post percutaneous coronary intervention (PCI) MACE associated with polyvascular disease (PVD) differs by sex., Methods: We analyzed 18,721 patients undergoing PCI at a tertiary-care center between 2012 and 2019. Polyvascular disease was defined as history of peripheral artery and/or cerebrovascular disease. The primary endpoint was MACE, a composite of all-cause death, myocardial infarction, or stroke at 1 year. Multivariate Cox regression was used to adjust for differences in baseline risk between patients with PVD vs. coronary artery disease (CAD) alone and interaction testing was used to assess risk modification by sex., Results: Women represented 29.2% (N = 5,467) of the cohort and were more likely to have PVD than men (21.7% vs. 16.1%; P < .001). Among both sexes, patients with PVD were older with higher prevalence of comorbidities and cardiovascular risk factors. Women with PVD had the highest MACE rate (10.0%), followed by men with PVD (7.2%), women with CAD alone (5.0%), and men with CAD alone (3.6%). Adjusted analyses revealed similar relative MACE risk associated with PVD vs. CAD alone in women and men (adjusted hazard ratio [aHR] 1.54, 95% confidence interval [CI] 1.20-1.99; P < .001 and aHR 1.31, 95% CI 1.06-1.62; P = .014, respectively; p-interaction = 0.460)., Conclusion: Women and men derive similar excess risk of MACE from PVD after PCI. The heightened risk associated with PVD needs to be addressed with maximized use of secondary prevention in both sexes., Competing Interests: Conflict of Interest Dr. Spirito received a research grant from the Swiss National Science Foundation.

Data on percutaneous coronary intervention (PCI) for left main coronary artery (LMCA) disease in patients of diverse race/ethnicity is scant. The aim of the study was to assess the impact of race/ethnicity on clinical outcomes at 12-month follow-up of patients with LMCA disease undergoing PCI with drug-eluting stent implantation. All patients undergoing PCI for LMCA disease between 2010 and 2019 at a tertiary care center were prospectively enrolled. Clinical outcomes were assessed per each race/ethnic group. The primary endpoint was the composite of all-cause death, myocardial infarction (MI), or stroke at 12 months. A total of 774 consecutive patients with known race/ethnicity were prospectively enrolled, 62.1% (n=481) Caucasians, 17.2% (n=133) Hispanics, 12.7% (n=98) Asians and 8.0% (n=62) African Americans. Compared with Caucasians, the hazard rate of the primary endpoint tended to be lower in Asian patients (6.1% vs 14.2%; hazard ratio [HR]: 0.41; 95% confidence interval [CI]: 0.16-1.03), and similar in African American (13.7% vs 14.2%; HR: 0.93; 95% CI: 0.40-2.16) and Hispanic patients (14.2% vs 14.2%; HR: 1.02; 95% CI: 0.58-1.78). Hazard rates of target vessel or lesion revascularization were comparable in the four groups. Cox multivariable regression adjustment confirmed consistent findings and revealed higher hazard rate of post-discharge bleeding in African Americans vs. Caucasians (HR: 5.89; 95% CI: 1.00-34.5). In conclusion, within a racially/ethnically diverse cohort of patients undergoing PCI for LMCA disease, when compared with Caucasians, Asians are at lower risk of all-cause death, MI or stroke, while African Americans are at increased risk of post-discharge bleeding., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Primary human hepatocyte (PHH) models have limited longevity and require high inoculum for HBV infection with minimal spread. We aimed to develop 3D cell culture models to overcome the limitations of existing models and to expand their utility for drug-related studies. Here, we report the establishment of two spheroid models utilizing de novo HBV-infected mouse-passaged (mp)PHH and mpPHH isolated from HBV-infected liver chimeric mice (HBV-mpPHH). Our data demonstrates that our models maintain detectable infection and human albumin levels up to 75 days, and therefore have enhanced longevity compared to existing models. As a proof-of-concept we used our de novo HBV-infected model as a drug-testing platform to validate an HBV capsid assembly modulator (CpAM). We report that we have established two HBV-infected 3D cell culture models and have characterized these models as practical and novel approaches with the potential to enhance the relevance and scope of in vitro HBV studies., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Aims: In standard time-to-first event analysis, early aspirin discontinuation followed by ticagrelor monotherapy has been shown to reduce bleeding without increasing ischemic complications compared with ticagrelor plus aspirin after percutaneous coronary intervention (PCI). We evaluated whether these treatment effects are preserved when recurrent events are considered., Methods and Results: In this TWILIGHT trial post hoc analysis, we assessed the effects of ticagrelor monotherapy on the total number of events that occurred over the 12-month follow-up among 7 119 high-risk patients randomized to aspirin or placebo in addition to ticagrelor at 3 months post-PCI if event-free and adherent to treatment. There were 391 patients with at least one Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding (primary endpoint). Of those, 28 (7.2%) had a recurrent event. The total number of BARC 2, 3, or 5 bleeding events were 148 in the ticagrelor monotherapy arm compared with 278 with ticagrelor plus aspirin arm (p < 0.001). Among 272 patients with at least one key secondary ischemic endpoint (all-cause death, myocardial infarction, or stroke), 37 (13.6%) sustained a recurrent event. Total ischemic events were similar (155 vs 159) in the two groups., Conclusions: Among selected high-risk patients who underwent PCI and completed 3 months of dual antiplatelet therapy followed by ticagrelor with or without aspirin, recurrent bleeding was less common than recurrent ischemic events over 12 months. Analysis of total events indicates that ticagrelor monotherapy continues to be more effective than ticagrelor plus aspirin in reducing bleeding without a signal of ischemic harm., (© The Author(s) 2024.

Background: Diabetes mellitus (DM) is a modifiable risk factor for patients with coronary artery disease (CAD). Treatment with insulin correlates with advanced disease and has been associated with excess cardiovascular risk, but evidence on outcomes of patients with insulin-treated DM (ITDM) undergoing left main percutaneous coronary intervention (LMPCI) remains scarce., Aims: The aim of the presented study is to evluate the risk attributable to DM and ITDM in patients undergoing LMPCI., Methods: We included 869 patients undergoing PCI for unprotected LMCAD. The cohort was divided into three subgroups based on diabetic status: No DM, ITDM, and Non-ITDM. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of death, spontaneous myocardial infarction (MI), or stroke at 1 year. Results were adjusted for clinically relevant baseline characteristics., Results: Amongst participants, 58.7% had no DM, 25.9% non-ITDM, and 15.4% ITDM. Diabetics were younger and more likely to be female. They also exhibited higher body mass index as well as prevalence of comorbidities, including hypertension, anemia, and chronic kidney disease. The number of bifurcation lesions and stents used was similar between groups. At 1 year, when compared to no DM, ITDM (25.4% vs. 10.0%, p < 0.01) but not non-ITDM (10.8% vs. 10.0%, p = 0.94) demonstrated higher MACCE. This finding was driven by increased risk of MI. Mortality was 8.4%, 7.8%, and 17.2% for no DM, Non-ITDM, and ITDM, respectively. Results remained unchanged after adjustment., Conclusions: In a rather contemporary patient population undergoing PCI for LMCAD, ITDM but not non-ITDM was associated with higher risk of 1-year MACCE, primarily driven by MI., (© 2024 Wiley Periodicals LLC.)

Human coronaviruses are a continuous threat to the human population and have limited antiviral treatments, and the recent COVID-19 pandemic sparked interest in finding new antiviral strategies, such as natural products, to combat emerging coronaviruses. Rapid efforts in the scientific community to identify effective antiviral agents for coronaviruses remain a focus to minimize mortalities and global setbacks. In this study, an essential oil derived from Myrtus communis L. (MEO) is effective against HCoV-229E and HCoV-OC43 virus infections in comparison to two FDA-approved drugs, Remdesivir and Nirmatrelvir. Gas-chromatography and mass spectrometry were used to identify the chemical composition of MEO. Slight antioxidant activity was observed in MEO, indicating a role in oxidative stress. A dose-response curve measuring the EC 50 indicates a high potency against HCoV-229E and HCoV-OC43 virus infections on Huh7.5 cells with low cytotoxicity using a PrestoBlue cell viability assay. Our findings demonstrate that MEO exhibits potent antiviral activity against HCoV-229E and HCoV-OC43 on Huh7.5 cells within a low-cytotoxicity range, but not on SARS-CoV-2. Artificial bacterial chromosome plasmids that expressed SARS-CoV-2 used for replicon-to determine viral replication and viral assembly/egress on HEK293T/17 cells-and virus-like particles on Huh7.5-AT cells-to determine viral entry and assembly/egress-showed no antiviral activity with MEO in comparison to Remdesivir. This study reveals the potential effectiveness of MEO as an alternative natural remedy to treat human coronaviruses and a potential antiviral agent for future coronavirus infections.

Background: Cerebrovascular events remain one of the most devastating complications of transcatheter aortic valve implantation (TAVI). Data from real-world contemporary cohorts on longitudinal trends and outcomes remain limited. The aim of this study was to assess incidence, temporal trends, predictors, and outcomes of cerebrovascular events following transfemoral TAVI., Methods and Results: The CENTER2 (Cerebrovascular Events in Patients Undergoing Transcatheter Aortic Valve Implantation With Balloon-Expandable Valves Versus Self-Expandable Valves 2) study includes patients undergoing TAVI between 2007 and 2022. The database contains pooled patient-level data from 10 clinical studies. A total of 24 305 patients underwent transfemoral TAVI (mean age 81.5±6.7 years, 56% women, median Society of Thoracic Surgeon Predicted Risk of Mortality 4.9% [3.1%-8.5%]). Of these patients, 2.2% (n=534) experienced stroke in the first 30 days after TAVI, and 40 (0.4%) had a transient ischemic attack. Stroke rates remained stable during the treatment period (2007-2010: 2.1%, 2011-2014: 2.5%, 2015-2018: 2.1%, 2019-2022: 2.1%; P trend =0.28). Moreover, 30-day cerebrovascular event rates were similar across Society of Thoracic Surgeon Predicted Risk of Mortality risk categories: 2.1% in low-risk, 2.6% in intermediate-risk, and 2.5% in high-risk patients ( P =0.21). Mortality was higher in patients with 30-day stroke than without at 30 days (20.3% versus 4.7%; odds ratio, 5.1 [95% CI, 4.1-6.5]; P <0.001) and at 1 year (44.1% versus 15.0%; hazard ratio, 3.5 [95% CI, 3.0-4.2]; P <0.001). One-year mortality rates for stroke did not decline over time (2007-2010: 46.9%, 2011-2014: 46.0%, 2015-2018: 43.0%, 2019-2022: 39.1%; P trend =0.32). At 1 year, 7.0% of patients undergoing TAVI had a stroke., Conclusions: In 24 305 patients who underwent transfemoral TAVI, 30-day cerebrovascular event incidence remained ≈ 2.2% between 2007 and 2022. Thirty-day stroke rates were similar throughout Society of Thoracic Surgeon Predicted Risk of Mortality risk categories. Mortality rates after stroke remain high., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03588247.

Background: It remains unclear whether procedural myocardial infarction (pMI) and spontaneous myocardial infarction (spMI) have a similar impact on prognosis., Objectives: The aim of this study was to assess mortality after pMI and spMI., Methods: Patients with chronic coronary syndrome (CCS) and baseline troponin ≤1× the upper reference level (URL) or with acute spMI who underwent percutaneous coronary intervention (PCI) were included. PMI was defined as post-PCI troponin increase >1× URL in patients with CCS. SpMI comprised any acute coronary syndrome with elevated troponin. The 1-year risk of all-cause death was assessed after pMI and spMI across 3 strata of troponin elevation (>1-5×, >5-35×, and >35× URL), with CCS patients having post-PCI troponin ≤1× URL as a reference group. Conventional troponin I was measured using the Architect methodology (Abbott)., Results: Among 10,707 patients undergoing PCI from 2012 to 2020, 8,515 patients presented with CCS and 2,192 with spMI. Among CCS patients, 913 (10.7%) had pMI. Troponin peaks >1-5×, >5-35×, and >35× URL were observed in 53%, 41%, and 6% of patients with pMI, and in 24%, 38%, and 37% of patients with spMI, respectively. Mortality at 1 year was higher after pMI (7.7%; adjusted HR: 4.40; 95% CI: 1.59-12.2), and spMI (8.5%; adjusted HR: 7.57; 95% CI: 5.44-10.5) with troponin peak >35× URL compared with no-MI (1.4%). Mortality was also increased after spMI with troponin peak >1-5× or >5-35× URL., Conclusions: Mortality at 1 year was significantly increased after pMI and spMI with troponin peak >35× URL, whereas for troponin levels ≤35× only spMI had a relevant impact on mortality., Competing Interests: Funding Support and Author Disclosures Dr Spirito has received a research grant from the Swiss National Science Foundation.

Introduction: High-risk percutaneous coronary interventions (HRPCI) are a potential treatment option for patients with reduced left ventricular ejection fraction (LVEF) and coronary artery disease. The extent to which such intervention is coupled with improvement in LVEF and associated with favorable outcomes is unknown., Methods: We aimed to characterize the incidence and correlates of LVEF improvement after Impella-guided HRPCI, and compare clinical outcomes in patients with versus without LVEF improvement. Data on consecutive patients undergoing Impella-guided HRPCI from a single center registry were analyzed. LVEF-improvement was defined as an absolute increase of LVEF of ≥10% measured at ≥30-days after intervention. The primary outcome was a composite of all-cause death, myocardial infarction or target vessel revascularization within 1-year., Results: Out of 161 consecutive patients undergoing Impella-guided HRPCI from June 2008 to December 2017, 43% ( n  = 70) demonstrated LVEF-improvement (baseline LVEF of 25.09 ± 6.19 to 33.30 ± 11.98 post intervention). Patients without LVEF-improvement had higher frequency of previous MI (61.5% vs. 37.1%, p  = 0.0021), Q-waves on ECG (17.6% vs. 5.7%, p  = 0.024) and higher SYNTAX scores (30.8 ± 17.6 vs. 25.2 ± 12.2; p  = 0.043). After correction of these confounders by multivariable analysis, no significant differences were found regarding the composite endpoint in patients with versus without LVEF-improvement (34.9% vs. 38.3%; p  = 0.48)., Discussion: In this single-center retrospective analysis, we report the following findings. First, LVEF improvement of at least 10% was documented in over 40% of patients undergoing Impella supported high-risk PCI. Second, a history of MI, Q-waves on admission ECG, and higher baseline SYNTAX scores were independent correlates of no LVEF improvement. Third, one year rates of adverse CV events were substantial and did not vary by the presence or absence of LVEF improvement Prospective studies with longer follow-up are needed to elucidate the impact of LVEF improvement on clinical outcomes., Competing Interests: GD has received consulting fees and honoraria from Johnson & Johnson, Sanofi, Covidien, The Medicines Company, Merck, CSL Behring, AstraZeneca, Medtronic, Abbott, Bayer, Boston Scientific, Osprey Medical, and GE Healthcare; and research grant support from Sanofi, Bristol-Myers Squibb, and Eli Lilly & Company/Daiichi-Sankyo.

Percutaneous coronary intervention (PCI) has demonstrated its safety and efficacy in treating left main (LM) coronary artery disease (CAD) in select patients. Polyvascular disease (PolyVD) is associated with adverse events in all-comers with CAD. However, there is little data examining the interplay between PolyVD and LM-PCI, which we sought to investigate in a retrospective single-center study. We included patients who underwent unprotected LM-PCI at a tertiary center from 2012 to 2019. The study population was stratified based on the presence or absence of PolyVD (i.e., medical history of cerebrovascular and/or peripheral artery disease in addition to LM-CAD). The primary outcome was major adverse cardiovascular events (MACE) combining all-cause mortality and spontaneous myocardial infarction within 1 year after index PCI. Overall, 869 patients were included, and 23.8% of the population had PolyVD. Subjects with PolyVD were older and had a greater burden of co-morbidities. After 1-year follow-up, PolyVD patients exhibited significantly higher rates of both MACE (22.8% vs 9.4%, p <0.001) and bleeding events compared with those without PolyVD. MACE was primarily driven by an increase in all-cause mortality (18.3% vs 7.1%, p <0.001). Results persisted after adjusting for confounders. In conclusion, in patients who underwent LM-PCI, the presence of PolyVD is linked to an increased risk of MACE and bleeding after 1 year of follow-up, which highlights the vulnerability of this population., Competing Interests: Declaration of competing interest Dr. Dangas received research grants from institutions and support for attending meetings from Daiichi Sankyo.

Background: Individuals suffering from polyvascular atherosclerotic disease (PolyVD) face a higher likelihood of adverse cardiovascular events. Additionally, inflammation, assessed by high-sensitivity C-reactive protein (hsCRP), affects residual risk following percutaneous coronary intervention (PCI). We aimed to explore the interplay between PolyVD and hsCRP in terms of clinical outcomes after PCI., Methods: Patients undergoing PCI for chronic coronary disease at a tertiary center between January 2012 and February 2020 were included for the current analysis. PolyVD was defined by additional history of cerebrovascular and/or peripheral artery disease. HsCRP levels were defined as elevated when the measured baseline concentration was > 3 mg/L. The primary outcome of interest was major adverse cardiovascular events (MACE), a composite of all-cause mortality, spontaneous MI, or target vessel revascularization., Results: Overall, 10,359 participants were included in the current study, with 17.4% affected by PolyVD and 82.6% included in the non-PolyVD subgroup. Patients with PolyVD had higher hsCRP levels than those without. Among the PolyVD group, a larger proportion (33.6%) exhibited elevated hsCRP compared to the non-PolyVD group (24.7%). Patients with both PolyVD and elevated hsCRP levels had significantly higher adverse event rates than all other subgroups at 1-year follow-up. Furthermore, an independent association between elevated hsCRP and MACE was observed within the PolyVD population, while this was not the case for individuals without PolyVD., Conclusion: A residual risk of adverse outcomes after PCI linked to inflammation appears to be present among individuals with PolyVD. This could help define further target populations for anti-inflammatory treatment options., (© 2024. Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: Patients with previous coronary artery bypass surgery (CABG) who require repeat revascularization frequently undergo percutaneous coronary intervention (PCI). We sought to identify factors associated with the decision to intervene on the native vessel versus a bypass graft and investigate their outcomes in a large nationwide prospective registry., Methods: We identified patients who underwent PCI with a history of prior CABG from the Netherlands Heart Registration between 2017 and 2021 and stratified them by isolated native vessel PCI versus PCI including at least one venous- or arterial graft. The primary endpoint of major adverse cardiac events (MACE) was a composite of all-cause death and target vessel revascularization (TVR) at one-year post PCI. The key secondary endpoint was a composite of all-cause death, myocardial infarction (MI), and TVR at 30 days., Results: Out of 154,146 patients who underwent PCI, 12,822 (8.3%) had a prior CABG. Isolated native vessel PCI was most frequently performed (75.2%), while an acute coronary syndrome (ACS) presentation was most strongly associated with graft interventions. The primary outcome of MACE at one-year post PCI occurred more frequently in interventions including grafts compared with native vessels alone (19.7% vs. 14.3%; adjOR 1.267; 95% CI 1.101-1.457); p < 0.001) driven by TVR. There was however no difference in mortality or the key secondary endpoint between the two groups., Conclusion: In this nationwide prospective registry, ACS presentation was strongly associated with bypass graft PCI. At one year after PCI, interventions including bypass grafts had a higher composite of MACE compared with isolated native vessel interventions., (Copyright © 2024 The Authors.

Despite impressive improvements in the care of patients with ST-segment elevation myocardial infarction, mortality remains high. Reperfusion is necessary for myocardial salvage, but the abrupt return of flow sets off a cascade of injurious processes that can lead to further necrosis. This has been termed myocardial ischemia-reperfusion injury and is the subject of this review. The pathologic and molecular bases for myocardial ischemia-reperfusion injury are increasingly understood and include injury from reactive oxygen species, inflammation, calcium overload, endothelial dysfunction, and impaired microvascular flow. A variety of pharmacologic strategies have been developed that have worked well in preclinical models and some have shown promise in the clinical setting. In addition, there are newer mechanical approaches including mechanical unloading of the heart prior to reperfusion that are in current clinical trials., Competing Interests: Funding Support and Author Disclosures Dr Welt has served as a consultant to Xenter Inc and Faraday Pharmaceuticals.

Background: Patients may prefer percutaneous coronary intervention (PCI) over coronary artery bypass graft (CABG) surgery, despite heart team recommendations. The outcomes in such patients have not been examined. We sought to examine the results of PCI in patients who were recommended for but declined CABG., Methods and Results: Consecutive patients with stable ischemic heart disease and unprotected left main or 3-vessel disease or Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score >22 who underwent PCI after heart team review between 2013 and 2020 were included. Patients were categorized into 3 groups according to heart team recommendations on the basis of appropriate use criteria: (1) PCI-recommended; (2) CABG-eligible but refused CABG (CABG-refusal); and (3) CABG-ineligible. The primary end point was the composite of death, myocardial infarction, or stroke at 1 year. The study included 3687 patients undergoing PCI (PCI-recommended, n=1718 [46.6%]), CABG-refusal (n=1595 [43.3%]), and CABG-ineligible (n=374 [10.1%]). Clinical and procedural risk increased across the 3 groups, with the highest comorbidity burden in CABG-ineligible patients. Composite events within 1 year after PCI occurred in 55 (4.1%), 91 (7.0%), and 41 (14.8%) of patients in the PCI-recommended, CABG-refusal, and CABG-ineligible groups, respectively. After multivariable adjustment, the risk of the primary composite outcome was significantly higher in the CABG-refusal (hazard ratio [HR], 1.67 [95% CI, 1.08-3.56]; P =0.02) and CABG-ineligible patients (HR, 3.26 [95% CI, 1.28-3.65]; P =0.004) groups compared with the reference PCI-recommended group, driven by increased death and stroke., Conclusions: Cardiovascular event rates after PCI were significantly higher in patients with multivessel disease who declined or were ineligible for CABG. Our findings provide real-world data to inform shared decision-making discussions.

Background: The optimal antiplatelet regimen after percutaneous coronary intervention (PCI) in patients with peripheral artery disease (PAD) is still debated. This analysis aimed to compare the effect of ticagrelor monotherapy versus ticagrelor plus aspirin in patients with PAD undergoing PCI., Methods: In the TWILIGHT trial, patients at high ischemic or bleeding risk that underwent PCI were randomized after 3 months of dual antiplatelet therapy (DAPT) to aspirin or matching placebo in addition to open-label ticagrelor for 12 additional months. In this post-hoc analysis, patient cohorts were examined according to the presence or absence of PAD. The primary endpoint was Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding. The key secondary endpoint was a composite of all-cause death, myocardial infarction (MI), or stroke. Endpoints were assessed at 12 months after randomization., Results: Among 7,119 patients, 489 (7%) had PAD and were older, more likely to have comorbidities, and multivessel disease. PAD patients had more bleeding or ischemic complications than no-PAD patients. Ticagrelor monotherapy compared to ticagrelor plus aspirin was associated with less BARC 2, 3, or 5 bleeding in PAD (4.6% vs 8.7%; HR 0.52; 95%CI 0.25-1.07) and no-PAD patients (4.0% vs 7.0%; HR 0.56; 95%CI 0.45-0.69; interaction P-value .830) and a similar risk of death, MI, or stroke in these 2 groups (interaction P-value .446)., Conclusions: Despite their higher ischemic and bleeding risk, patients with PAD undergoing PCI derived a consistent benefit from ticagrelor monotherapy after 3 months of DAPT in terms of bleeding reduction without any relevant increase in ischemic events.

Background: The number of octogenarians referred to percutaneous coronary interventions (PCI) is rising steadily. The prevalence and prognostic impact of complex PCI (CPCI) in this vulnerable population has not been fully evaluated., Methods: Patients ≥80 years old who underwent PCI between 2012 and 2019 at Mount Sinai Hospital were included. Patients were categorized based on PCI complexity, defined as the presence of at least one of the following criteria: use of atherectomy, total stent length ≥60 mm, ≥3 stents implanted, bifurcation treated with at least 2 stents, PCI involving ≥3 vessels, ≥3 lesions, left main, saphenous vein graft or chronic total occlusion. The primary outcome was major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction (MI), or target-vessel revascularization (TVR), within 1 year after PCI. Secondary outcomes included major bleeding., Results: Among 2657 octogenarians, 1387 (52%) underwent CPCI and were more likely to be men and to have cardiovascular risk factors or comorbidities. CPCI as compared with no-CPCI was associated with a higher 1-year risk of MACE (16.6% vs. 11.1%, adjusted HR 1.3, 95% CI 1.06-1.77, p value 0.017), due to an excess of MI and TVR, and major bleeding (10% vs. 5.8%, adjusted HR 1.64, 95% CI 1.20-2.55, p value 0.002)., Conclusions: Among octogenarians, CPCI was associated with a significantly higher 1-year risk of MACE, due to higher rates of MI and TVR but not of all-cause death, and of major bleeding. Strategies to reduce complications should be implemented in octogenarians undergoing CPCI., (© 2024 Wiley Periodicals LLC.)

Background: Diabetes mellitus (DM) is associated with a high rate of major adverse cardiac events (MACE) after de novo coronary artery percutaneous coronary intervention (PCI). Whether patients with DM undergoing PCI for in-stent restenosis (ISR) experience a similar heightened risk of MACE is not known. Hence, we sought to compare the clinical outcomes of patients with and without DM undergoing PCI for ISR., Methods: Patients undergoing first episode ISR PCI between January 2015 and December 2021 were included. The primary outcome of interest was MACE (all-cause death, myocardial infarction [MI], and target lesion revascularization [TVR]) at 1-year., Results: A total of 3156 patients (56.7% with DM) underwent PCI for ISR during the study period. Patients with DM were younger, more likely to be female, and had a higher prevalence of comorbidities. At 1-year follow-up, DM was associated with a higher rate of MACE (22.4% vs. 18.7%, unadjusted HR 2.03, 95%CI(1.27-3.25), p = 0.003). All-cause mortality and MI were significantly more frequent among people with DM at 1-year follow-up. The rate of TVR was similar in both groups (17.9% vs. 16.0%, unadjusted HR 1.14, 95%CI (0.94-1.37), p = 0.180). On adjusted analysis, there was no significant difference in the rate of MACE (AHR 1.07, 95%CI(0.90 - -1.29), p = 0.444), all-cause death (AHR 1.54, 95%CI(0.93-2.54), p = 0.095) or MI (AHR 1.10, 95%CI(0.74-1.63), p = 0.652)., Conclusion: ISR PCI in patients with DM was associated with a higher rate of MACE at 1-year follow-up. However, this increased risk was no longer significant after adjusting for baseline characteristics., Competing Interests: Declaration of competing interest A.

The treatment of severe aortic stenosis (SAS) has evolved rapidly with the advent of minimally invasive structural heart interventions. Transcatheter aortic valve replacement has allowed patients to undergo definitive SAS treatment achieving faster recovery rates compared to valve surgery. Not infrequently, patients are admitted/diagnosed with SAS after a fall associated with a hip fracture (HFx). While urgent orthopedic surgery is key to reduce disability and mortality, untreated SAS increases the perioperative risk and precludes physical recovery. There is no consensus on what the best strategy is either hip correction under hemodynamic monitoring followed by valve replacement or preoperative balloon aortic valvuloplasty to allow HFx surgery followed by valve replacement. However, preoperative minimalist transcatheter aortic valve replacement may represent an attractive strategy for selected patients. We provide a management pathway that emphasizes an early multidisciplinary approach to optimize time for hip surgery to improve orthopedic and cardiovascular outcomes in patients presenting with HFx-SAS., Competing Interests: Funding support was received from the Section of Cardiology, John W.

Background: Dialysis is a rare but serious complication after transcatheter aortic valve replacement. We analyzed the large multicenter TRITAVI (transfusion requirements in transcatheter aortic valve implantation) registry in order to develop and validate a clinical score assessing this risk., Methods and Results: A total of 10 071 consecutive patients were enrolled in 19 European centers. Patients were randomly assigned (2:1) to a derivation and validation cohort. Two scores were developed, 1 including only preprocedural variables (TRITAVIpre) and 1 also including procedural variables (TRITAVIpost). In the 6714 patients of the derivation cohort (age 82±6 years, 48% men), preprocedural factors independently associated with dialysis and included in the TRITAVIpre score were male sex, diabetes, prior coronary artery bypass graft, anemia, nonfemoral access, and creatinine clearance <30 mL/min per m 2 . Additional independent predictors among procedural features were volume of contrast, need for transfusion, and major vascular complications. Both scores showed a good discrimination power for identifying risk for dialysis with C-statistic 0.78 for TRITAVIpre and C-statistic 0.88 for TRITAVIpost score. Need for dialysis increased from the lowest to the highest of 3 risk score groups (from 0.3% to 3.9% for TRITAVIpre score and from 0.1% to 6.2% for TRITAVIpost score). Analysis of the 3357 patients of the validation cohort (age 82±7 years, 48% men) confirmed the good discrimination power of both scores (C-statistic 0.80 for TRITAVIpre and 0.81 for TRITAVIpost score). Need for dialysis was associated with a significant increase in 1-year mortality (from 6.9% to 54.4%; P =0.0001)., Conclusions: A simple preprocedural clinical score can help predict the risk of dialysis after transcatheter aortic valve replacement.

Background: Dual antiplatelet therapy with a potent P2Y 12 inhibitor coupled with aspirin for 1 year is the recommended treatment for patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). As an alternative, monotherapy with a P2Y 12 inhibitor after a short period of dual antiplatelet therapy has emerged as a bleeding reduction strategy., Methods: We pooled individual patient data from randomized trials that included patients with ACS undergoing PCI treated with an initial 3-month course of dual antiplatelet therapy followed by ticagrelor monotherapy versus continued ticagrelor plus aspirin. Patients sustaining a major ischemic or bleeding event in the first 3 months after PCI were excluded from analysis. The primary outcome was Bleeding Academic Research Consortium type 3 or 5 bleeding occurring between 3 and 12 months after index PCI. The key secondary end point was the composite of death, myocardial infarction, or stroke. Hazard ratios and 95% CIs were generated using Cox regression with a one-stage approach in the intention-to-treat population., Results: The pooled cohort (n=7529) had a mean age of 62.8 years, 23.2% were female, and 55% presented with biomarker-positive ACS. Between 3 and 12 months, ticagrelor monotherapy significantly reduced Bleeding Academic Research Consortium 3 or 5 bleeding compared with ticagrelor plus aspirin (0.8% versus 2.1%; hazard ratio, 0.37 [95% CI, 0.24-0.56]; P <0.001). Rates of all-cause death, myocardial infarction, or stroke were not significantly different between groups (2.4% versus 2.7%; hazard ratio, 0.91 [95% CI, 0.68-1.21]; P =0.515). Findings were unchanged among patients presenting with biomarker-positive ACS., Conclusions: Among patients with ACS undergoing PCI who have completed a 3-month course of dual antiplatelet therapy, discontinuation of aspirin followed by ticagrelor monotherapy significantly reduced major bleeding without incremental ischemic risk compared with ticagrelor plus aspirin., Registration: URL: https://www.crd.york.ac.uk/prospero; Unique identifier: CRD42023449646., Competing Interests: Disclosures Dr Baber received honoraria/consulting fees from AstraZeneca, Amgen, Boston Scientific, and Abbott.

Background: Peripheral artery disease (PAD) is associated with worse outcomes after percutaneous coronary intervention (PCI). The aim of this study was to assess the prognostic impact of PAD according to high bleeding risk (HBR) status., Methods: Consecutive patients undergoing PCI with drug-eluting stent implantation at a tertiary-care center (Mount Sinai Hospital) between 2012 and 2019 were stratified according to HBR and PAD status. The primary outcome was major adverse cardiac events (MACE), a composite of all-cause death, myocardial infarction (MI), and stroke 1 year after PCI. Secondary outcomes included major bleeding., Results: Out of 16,750 patients, 43% were HBR and 57% were no-HBR. Within the two groups, PAD patients were 14% and 6%, respectively, and were more likely to have comorbidities and to undergo complex PCI than no-PAD patients. Within the HBR group, PAD was associated with an increased risk of MACE (11.4% vs. 7.3%, hazard ratio [HR]: 1.59, 95% confidence interval [CI]: 1.27-1.99, p < 0.001) and a numerical nonsignificant increase of major bleeding (8.5% vs. 6.9%, HR: 1.25, 95% CI: 0.98-1.59, p = 0.066) as compared with no-PAD. Among no-HBR patients, rates of MACE and major bleeding were numerically but not significantly higher in the PAD group. After multivariable adjustment, PAD was no longer a predictor of adverse outcomes, irrespective of HBR status., Conclusions: At 1-year after PCI, PAD was associated with increased 1-year risks of MACE in HBR patients. After adjustment for cardiovascular risk factors and comorbidities, the effect of PAD on adverse events was largely attenuated., (© 2024 Wiley Periodicals LLC.)

Background: Among patients undergoing percutaneous coronary intervention (PCI), in-stent restenosis (ISR) is related with a worse prognosis, while higher body mass index (BMI) values are associated with better outcomes. It is unclear whether the prognostic impact of ISR varies in function of BMI., Methods: Patients undergoing PCI at a large center from 2012 to 2019 not presenting with an acute myocardial infarction (MI) were included. Subjects with BMI < 18.5 kg/m 2 or treated with bare metal stents were excluded. Patients were stratified according to type of lesion treated (ISR vs. no-ISR) and into four BMI categories: normal weight (BMI 18.5-25 kg/m 2 ), overweight (25.0-29.9 kg/m 2 ), class I obesity (30.0-34.9 kg/m 2 ), class II-III obesity (≥35.0 kg/m 2 ). The primary outcome was major adverse cardiovascular events (MACE), a composite of all-cause death, MI, and target vessel revascularization (TVR) at 1 year., Results: Out of 16,234 patients, 3694 (23%) underwent PCI for ISR. ISR as compared to no-ISR was associated with a consistent increased risk of MACE within the normal weight (18.8% vs. 7.8%, adj. hazard ratio (HR): 1.99, 95% confidence interval [CI]: 1.51-2.64), overweight (19.1% vs. 6.4%, adj. HR: 2.35, 95% CI: 1.91-2.88), class I obesity (18.3% vs. 6.8%, adj. HR: 1.95, 95% CI: 1.47-2.57), and class II-III obesity (16.4% vs. 7.4%, adj. HR: 1.61, 95% CI: 1.09-2.37) groups (interaction p-value: 0.192). The ISR-related risks were mostly driven by an excess of TVR., Conclusions: At 1 year, ISR was associated with an increased risk of MACE irrespective of BMI, mostly due to an excess of TVR after ISR., (© 2024 Wiley Periodicals LLC.)

Background: Patients with atrial fibrillation (AF) and a recent (≤ 90 days) percutaneous coronary intervention (PCI) undergoing transcatheter aortic valve implantation (TAVI) are at high bleeding risk due to the addition of oral antiplatelet (OAP) agents on top of oral anticoagulants. Data on outcomes of these patients are needed to optimize antithrombotic treatment., Methods: This analysis compared annualized clinical event rates in patients with and without a recent PCI enrolled in ENVISAGE-TAVI AF, a prospective, randomized, open-label, adjudicator-masked trial comparing edoxaban and vitamin K antagonists in AF patients after TAVI. The primary efficacy and safety outcomes were net adverse clinical events (NACE) and major bleeding., Results: Overall, 132 (94.3%) patients with a recent PCI (n = 140) received OAP after TAVI, compared with 692 (55.9%) patients without a recent PCI (n = 1237). Among patients with a recent PCI on OAP agents, use of dual antiplatelet therapy decreased to 5.5%, and use of single antiplatelet therapy (SAPT) increased to 78.0% over 3 months post-randomization. Conversely, use of SAPT predominated at all time points in patients without a recent PCI history. There were no significant differences in the incidence of NACE or other outcomes assessed, except for major bleeding events, which were more frequent in patients with vs without a recent PCI history (hazard ratio [95% confidence interval]: 2.17 [1.27, 3.73]; P = 0.005)., Conclusions: Patients with AF undergoing TAVI with a recent PCI have a similar risk of ischemic events and mortality, but an increased risk of major bleeding compared with patients without a recent PCI., (© 2024.

Aim: To assess the value of the thrombotic risk criteria proposed in the 2023 guidelines of the European Society of Cardiology (ESC) for the management of acute coronary syndrome (ACS) to predict the ischaemic risk after percutaneous coronary intervention (PCI)., Methods and Results: Consecutive patients with acute or chronic coronary syndrome undergoing PCI at a large tertiary-care center from 2014 to 2019 were included. Patients were stratified into low, moderate, or high thrombotic risk based on the ESC criteria. The primary endpoint was major adverse cardiovascular events (MACEs) at 1 year, a composite of all-cause death, myocardial infarction (MI), and stroke. Secondary endpoints included major bleeding. Among 11 787 patients, 2641 (22.4%) were at low-risk, 5286 (44.8%) at moderate risk, and 3860 (32.7%) at high-risk. There was an incremental risk of MACE at 1 year in patients at moderate (hazard ratios (HR) 2.53, 95% confidence interval (CI) 1.78-3.58) and high-risk (HR 3.39, 95% CI 2.39-4.80) as compared to those at low-risk, due to higher rates of all-cause death and MI. Major bleeding rates were increased in high-risk patients (HR 1.59, 95% CI 1.25-2.02), but similar between the moderate and low-risk group. The Harrell's C-index for MACE was 0.60., Conclusion: The thrombotic risk criteria of the 2023 ESC guidelines for ACS enable to stratify patients undergoing PCI in categories with an incremental 1 year risk of MACE; however, their overall predictive ability for MACE is modest. Future studies should confirm the value of these criteria to identify patients benefiting from an extended treatment with a second antithrombotic agent., (© The Author(s) 2023. Published by Oxford University Press on behalf of the European Society of Cardiology.)

Electrophysiological and interventional procedures have been increasingly used to reduce morbidity and mortality in patients experiencing cardiovascular diseases. Although antithrombotic therapies are critical to reduce the risk of stroke or other thromboembolic events, they can nonetheless increase the bleeding hazard. This is even more true in an aging population undergoing cardiac procedures in which the combination of oral anticoagulants and antiplatelet therapies would further increase the hemorrhagic risk. Hence, the timing, dose, and combination of antithrombotic therapies should be carefully chosen in each case. However, the maze of society guidelines and consensus documents published so far have progressively led to a hazier scenario in this setting. Aim of this review is to provide-in a single document-a quick, evidenced-based practical summary of the antithrombotic approaches used in different cardiac electrophysiology and interventional procedures to guide the busy clinician and the cardiac proceduralist in their everyday practice., Competing Interests: Funding Support and Author Disclosures The authors have reported that they have no relationships relevant to the contents of this paper to disclose., (Copyright © 2024 American College of Cardiology Foundation.

Background: Transfemoral (TF) access is default in transcatheter aortic valve implantation (TAVI). Transaxillary (TAx) access has been shown to be a safe alternative in case of prohibitive iliofemoral anatomy, but whether TAx as preferred access has similar safety and efficacy as TF access is unknown. The aim of this study was to compare outcomes between patients treated with self-expanding devices using TF or TAx route as preferred access in TAVI., Methods: A single center cohort of 354 patients treated using TAx as preferred access and a multi-center cohort of 5980 patients treated using TF access were compared. Propensity score matching was used to reduce selection bias and potential confounding. After propensity score matching, each group consisted of 322 patients. Clinical outcomes according to VARC-2 were compared using chi-square test., Results: In 6334 patients undergoing TAVI, mean age was 81.4 ± 7.0 years, 57% was female and median logistic EuroSCORE was 14.7% (IQR 9.5-22.6). In the matched population (age 79.3 ± 7.0, 50% female, logistic EuroSCORE 13.4%, IQR 9.0-21.5), primary outcomes 30-day and one-year all-cause mortality were similar between Tax and TF groups (30 days: 5% versus 6%, p = 0.90; 1 year: 20% versus 16%, p = 0.17). Myocardial infarction was more frequent in patients undergoing Tax TAVI compared with TF (4% versus 1%, p = 0.05), but new permanent pacemakers were less frequently implanted (12% versus 21%, p = 0.001)., Conclusion: TAx as preferred access is feasible and safe with outcomes that are comparable to TF access., Competing Interests: Conflict of interest statement Dr. van Wely is a proctor for Abbott Vascular.

Background: Bleeding is one of the most frequent complications in patients undergoing transcatheter aortic valve replacement (TAVR). Importantly, major bleeding is associated with poor clinical outcomes after TAVR. However, large studies on bleeding complications in the contemporary TAVR population are limited., Objectives: The aim of this study was to assess the incidence, temporal trends, clinical outcomes, and predictors of bleeding in patients undergoing transfemoral TAVR., Methods: The CENTER2 study is a pooled patient-level database from 10 clinical studies including patients who underwent TAVR between 2007 and 2022., Results: A total of 23,562 patients underwent transfemoral TAVR. The mean age was 81.5 ± 6.7 years, and 56% were women. Major bleeding within the first 30 days was observed in 1,545 patients (6.6%). Minor bleeding was reported in 1,143 patients (4.7%). Rates of major bleeding decreased from 11.5% in 2007-2010 to 5.5% in 2019-2022 (P trend  < 0.001). Dual antiplatelet therapy was associated with higher major bleeding rates compared with single antiplatelet therapy (12.2% vs 9.1%; OR: 1.40; 95% CI: 1.13-1.72; P = 0.002). Patients with major bleeding had increased mortality risk during the first 30 days (14.1% vs 4.3%; OR: 3.66; 95% CI: 3.11-4.31; P < 0.001) and during 1-year follow-up (27.8% vs 14.5%; HR: 1.50; 95% CI: 1.41-1.59; P < 0.001). Minor bleeding did not affect 1-year mortality risk (16.7% vs 14.5%; HR: 1.11; 95% CI: 0.93-1.32; P = 0.27). Predictors of major bleeding were female sex and peripheral vascular disease., Conclusions: Bleeding complications remain frequent and important in patients undergoing transfemoral TAVR. Increased mortality risk in major bleeding persists after the initial 30 days.

ENVISAGE-TAVI AF (Edoxaban versus Standard of Care and Their Effects on Clinical Outcomes in Patients Having Undergone Transcatheter Aortic Valve Implantation-Atrial Fibrillation; NCT02943785) was a prospective, randomized, open-label trial comparing non-vitamin K oral anticoagulant (NOAC) edoxaban with vitamin K antagonists (VKAs) in patients with atrial fibrillation after successful transcatheter aortic valve replacement (TAVR). The effect of edoxaban- or VKA-based therapy on patient-reported outcomes remains unknown, as most studies focus on efficacy and safety. Pre-TAVR patient-reported expectations and post-TAVR Treatment Satisfaction and Convenience with edoxaban or VKA treatment (at months 3 and 12) were analyzed using the Perception of Anticoagulation Treatment Questionnaire (PACT-Q). This analysis included randomized and dosed patients with an evaluable PACT-Q1 assessment at baseline and ≥1 postbaseline assessment (PACT-Q2). Subanalyses included patients stratified by pre-TAVR anticoagulant (NOAC, VKA, no NOAC/VKA). Edoxaban- (n = 585) and VKA-treated (n = 522) patients had similar baseline characteristics and treatment expectations. Pre-TAVR anticoagulant use did not affect treatment expectations. After TAVR, edoxaban-treated patients had significantly higher Treatment Satisfaction and Convenience scores compared with VKA-treated patients at all time points (p <0.001 for all). Among edoxaban-treated patients, those who received VKAs pre-TAVR were significantly more satisfied with treatment than those who received NOACs (p <0.001) or no NOACs/VKAs (p = 0.003); however, there was no significant difference in the perception of convenience (p = 0.927 and p = 0.092, respectively). Conversely, among VKA-treated patients, the type of anticoagulant used pre-TAVR did not affect Treatment Satisfaction or Convenience scores post-TAVR. In conclusion, patients with atrial fibrillation who received edoxaban post-TAVR reported significantly higher Treatment Satisfaction and Convenience scores compared with those who received VKAs, resulting in a clinically meaningful difference between treatment groups., Competing Interests: Declaration of Competing Interest Dr. Hengstenberg is a clinical proctor for Edwards Lifesciences and Boston Scientific; reports payment for speaker bureaus and support for attending meetings from Daiichi Sankyo, Inc.; and reports advisory board participation for Daiichi Sankyo, Inc.

The Bifurcation Academic Research Consortium (Bif-ARC) project originated from the need to overcome the paucity of standardization and comparability between studies involving bifurcation coronary lesions. This document is the result of a collaborative effort between academic research organizations and the most renowned interventional cardiology societies focused on bifurcation lesions in Europe, the United States, and Asia. This consensus provides standardized definitions for bifurcation lesions; the criteria to judge the side branch relevance; the procedural, mechanistic, and clinical endpoints for every type of bifurcation study; and the follow-up methods. Considering the complexity of bifurcation lesions and their evaluation, detailed instructions and technical aspects for site and core laboratory analysis of bifurcation lesions are also reported. The recommendations included within this consensus will facilitate pooled analyses and the effective comparison of data in the future, improving the clinical relevance of trials in bifurcation lesions, and the quality of care in this subset of patients.

Repeat coronary revascularization is a common adverse event after successful percutaneous coronary intervention. This analysis aimed to assess the effects of ticagrelor monotherapy on repeat clinically driven revascularization (CDR). In the TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients after Coronary Intervention) trial, after 3 months of ticagrelor plus aspirin, high-risk patients were maintained on ticagrelor and randomly allocated to aspirin or placebo for 1 year. The primary end point of this analysis was CDR within 12 months after randomization. The key secondary end points were major adverse cardiovascular and cerebrovascular events (MACCEs), a composite of all-cause death, myocardial infarction, stroke, or CDR, and net adverse clinical events (NACEs), including the individual components of MACCEs and clinically relevant bleeding. The analysis was performed in the per-protocol population. CDR occurred in 473 of 7,039 patients and was associated with a significantly higher risk of subsequent all-cause death, myocardial infarction, or stroke (adjusted hazard ratios [HRs] 2.92, 95% confidence interval [CI] 1.82 to 4.67). Ticagrelor monotherapy was associated with a similar 12-month risk of CDR (7.1% vs 6.6%; HR 1.09, 95% CI 0.90 to 1.30, p = 0.363) and MACCEs (8.9% vs 8.6%; HR 1.04, 95% CI 0.89 to 1.22, p = 0.619), and a lower risk of NACEs (12.2% vs 14.6%; HR 0.83 95% CI 0.73 to 0.94, p = 0.004) than ticagrelor plus aspirin. In conclusion, among high-risk patients who underwent percutaneous coronary intervention, ticagrelor monotherapy after 3 months of ticagrelor-based dual antiplatelet therapy was associated with a similar risk of CDR and MACCEs and a decrease of NACEs (TWILIGHT: NCT02270242)., Competing Interests: Declaration of Competing Interest Dr. Spirito received a research grant from the Swiss National Science Foundation (Bern, Switzerland).

Artificial intelligence, computational simulations, and extended reality, among other 21st century computational technologies, are changing the health care system. To collectively highlight the most recent advances and benefits of artificial intelligence, computational simulations, and extended reality in cardiovascular therapies, we coined the abbreviation AISER. The review particularly focuses on the following applications of AISER: 1) preprocedural planning and clinical decision making; 2) virtual clinical trials, and cardiovascular device research, development, and regulatory approval; and 3) education and training of interventional health care professionals and medical technology innovators. We also discuss the obstacles and constraints associated with the application of AISER technologies, as well as the proposed solutions. Interventional health care professionals, computer scientists, biomedical engineers, experts in bioinformatics and visualization, the device industry, ethics committees, and regulatory agencies are expected to streamline the use of AISER technologies in cardiovascular interventions and medicine in general., Competing Interests: Funding Support and Author Disclosures Supported by the National Institute of Health (R01 HL144690) and Dr Vincent Miscia Cardiovascular Research Fund.

Background: Nearly 20% of patients on ticagrelor experience dyspnea, which may lead to treatment discontinuation in up to one-third of cases., Objectives: The authors sought to evaluate the incidence, predictors, and outcomes of dyspnea-related ticagrelor discontinuation after percutaneous coronary intervention (PCI)., Methods: In the TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention) trial, after 3 months of ticagrelor plus aspirin, patients were maintained on ticagrelor and randomized to aspirin or placebo for 1 year. The occurrence of dyspnea associated with ticagrelor discontinuation was evaluated among all patients enrolled in the trial. A landmark analysis was performed at 3 months after PCI, that is, the time of randomization. Predictors of dyspnea-related ticagrelor discontinuation were obtained from multivariable Cox regression with stepwise selection of candidate variables., Results: The incidence of dyspnea-related ticagrelor discontinuation was 6.4% and 9.1% at 3 and 15 months after PCI, respectively. Independent predictors included Asian race (lower risk), smoking, prior PCI, hypercholesterolemia, prior coronary artery bypass, peripheral artery disease, obesity, and older age. Among 179 patients who discontinued ticagrelor because of dyspnea after randomization, ticagrelor monotherapy was not associated with a higher risk of subsequent ischemic events (composite of all-cause death, myocardial infarction, or stroke) compared with ticagrelor plus aspirin (5.0% vs 7.1%; P = 0.566)., Conclusions: In the TWILIGHT trial, dyspnea-related ticagrelor discontinuation occurred in almost 1 in 10 patients and tended to occur earlier rather than late after PCI. Several demographic and clinical conditions predicted its occurrence, and their assessment may help identify subjects at risk for therapy nonadherence., Competing Interests: Funding Support and Author Disclosures This work was supported by an investigator-initiated grant from AstraZeneca.

Background: The MITRAL (Mitral Implantation of Transcatheter Valves) trial is the first prospective trial to evaluate the safety and feasibility of balloon-expandable aortic transcatheter heart valves in patients with failed surgical bioprostheses or annuloplasty rings and severe mitral annular calcification treated with mitral valve-in-valve (MViV), valve-in-ring (MViR), or valve-in-mitral annular calcification (ViMAC)., Objectives: The aim of this study was to evaluate 5-year outcomes among these patients., Methods: A multicenter prospective study was conducted among patients at high surgical risk at 13 U.S. sites. Patients underwent MViV (n = 30), MViR (n = 30), or ViMAC (n = 31) and were followed annually for 5 years. Kansas City Cardiomyopathy Questionnaire scores were obtained at baseline and follow-up visits. Echocardiograms were analyzed at independent core laboratories., Results: A total of 91 patients underwent transcatheter mitral valve replacement (February 2015 to December 2017). The mean age was 74.3 ± 8.9 years. At 5-year follow-up, the lowest all-cause mortality was observed in the MViV group (21.4%), 94.7% of patients were in NYHA functional class I or II, and the mean mitral gradient was 6.6 ± 2.5 mm Hg. The MViR and ViMAC groups had higher all-cause mortality (65.5% and 67.9%), most survivors were in NYHA functional classes I and II (50% and 55.6%), and mean mitral gradients remained stable (5.8 ± 0.1 and 6.7 ± 2.5 mm Hg). Significant improvements in Kansas City Cardiomyopathy Questionnaire scores were observed when all 3 arms were pooled., Conclusions: MViV, MViR, and ViMAC procedures were associated with sustained improvement of heart failure symptoms and quality of life among survivors at 5 years. Transcatheter heart valve function remained stable in all 3 groups. Patients treated with MViV had excellent survival at 5 years, whereas survival was lower in the MViR and ViMAC groups, consistent with underlying disease severity. Patients with more residual mitral regurgitation had higher mortality., Competing Interests: Funding Support and Author Disclosures This study was partially supported by an unrestricted research grant from Edwards Lifesciences.

Aims: Based on recent clinical data, the 2020 ESC guidelines on non-ST-elevation acute coronary syndrome (NSTE-ACS) suggest to tailor antithrombotic strategy on individual thrombotic risk. Nonetheless, prevalence and prognostic impact of the high thrombotic risk (HTR) criteria proposed are yet to be described. In this analysis from the PROMETHEUS registry, we assessed prevalence and prognostic impact of HTR, defined according to the 2020 ESC NSTE-ACS guidelines, and if the benefits associated with prasugrel vs. clopidogrel vary with thrombotic risk., Methods and Results: PROMETHEUS was a multicentre prospective study comparing prasugrel vs. clopidogrel in ACS patients undergoing percutaneous coronary intervention (PCI). Patients were at HTR if presenting with one clinical plus one procedural risk feature. The primary endpoint was major adverse cardiac events (MACE), composite of death, myocardial infarction, stroke, or unplanned revascularization, at 1 year. Adjusted hazard ratio (adjHR) and 95% confidence intervals (CIs) were calculated with propensity score stratification and multivariable Cox regression. Among 16 065 patients, 4293 (26.7%) were at HTR and 11 772 (73.3%) at low-to-moderate thrombotic risk. The HTR conferred increased incidence of MACE (23.3 vs. 13.6%, HR 1.85, 95% CI 1.71-2.00, P < 0.001) and its single components. Prasugrel was prescribed in patients with less comorbidities and risk factors and was associated with reduced risk of MACE (HTR: adjHR 0.83, 95% CI 0.68-1.02; low-to-moderate risk: adjHR 0.75, 95% CI 0.64-0.88; pinteraction = 0.32)., Conclusion: High thrombotic risk, as defined by the 2020 ESC NSTE-ACS guidelines, is highly prevalent among ACS patients undergoing PCI. The HTR definition had a strong prognostic impact, as it successfully identified patients at increased 1 year risk of ischaemic events., Competing Interests: Conflict of interest: M.B.E. receives a pension from and has equity in Eli Lilly and Company.

Background: The TWILIGHT trial (NCT02270242) demonstrated that in selected high-risk patients undergoing percutaneous coronary intervention (PCI) ticagrelor monotherapy significantly reduced bleeding complications without ischemic harm as compared to ticagrelor plus aspirin after 3-month of dual antiplatelet therapy. The aim of this analysis was to assess the applicability of the findings TWILIGHT trial to a real-world population., Methods: Patients undergoing PCI at a tertiary center between 2012 and 2019 and not meeting any TWILIGHT exclusion criterion (oral anticoagulation treatment, ST-segment elevation myocardial infarction [MI], cardiogenic shock, dialysis, prior stroke, or thrombocytopenia) were included. Patients were stratified into 2 groups based on whether they fulfilled the TWILIGHT inclusion criteria (high-risk) or not (low-risk). The primary outcome was all-cause death; the key secondary outcomes were MI and major bleeding at 1 year after PCI., Results: Out of 13,136 included patients, 11,018 (83%) were at high risk. At 1-year, these patients had an approximately 3 folds greater hazard of death (1.4% vs 0.4%, HR 3.63, 95% CI 1.70-7.77) and MI (1.8% vs 0.6%, HR 2.81, 95% CI 1.56-5.04) and a nearly 2 folds higher risk of major bleeding (3.3% vs 1.8%, HR 1.86, 95% CI 1.32-2.62) as compared to low-risk patients., Conclusion: Among patients not meeting the TWILIGHT exclusion criteria from a large PCI registry, the high-risk inclusion criteria of the TWILIGHT trial were met by the majority of patients and were associated with an increased risk of mortality and MI and a moderately elevated risk of bleeding., (Copyright © 2023 Elsevier Inc.

Background: Data on the prognostic value of high-sensitivity C-reactive protein (hs-CRP) levels in patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI) are limited., Methods: Patients undergoing PCI at a tertiary center from January 2012 to December 2019 were included. CKD was defined as a glomerular filtration rate (GFR) <60 mL/min/1.73m 2 and elevated hs-CRP was defined as >3 mg/L. Acute myocardial infarction (MI), acute heart failure, neoplastic disease, patients undergoing hemodialysis, or hs-CRP >10 mg/L were exclusion criteria. The primary outcome was major adverse cardiac events (MACE), a composite of all-cause death, MI, and target vessel revascularization at 1-year after PCI., Results: Out of 12,410 patients, 3029 (24.4 %) had CKD. Elevated hs-CRP levels were found in 31.8 % of CKD and 25.8 % of no-CKD patients. At 1 year, MACE occurred in 87 (11.0 %) CKD patients with elevated hs-CRP and 163 (9.5 %) with low hs-CRP (adj. HR 1.26, 95 % CI 0.94-1.68); among no-CKD patients, in 200 (10 %) and 470 (8.1 %), respectively (adj. HR 1.21, 95 % CI 1.00-1.45). Hs-CRP was associated with an increased risk of all-cause death in both CKD (Adj. HR 1.92, 95 % CI 1.07-3.44) and no-CKD patients (adj. HR 3.02, 95 % CI 1.74-5.22). There was no interaction between hs-CRP and CKD status., Conclusions: Among patients undergoing PCI without acute MI, elevated hs-CRP values were not associated with a higher risk of MACE at 1 year, but with increased mortality hazards consistently in patients with or without CKD., (Copyright © 2023.

Background: Coronary stent infection (CSI) represents a rare but potentially fatal complication of percutaneous coronary interventions (PCI). A systematic review and meta-analysis of published reports was performed to profile CSI and its management strategies., Methods: Online database searches were performed using MeSH and keywords. The primary outcome of the study was in-hospital mortality. A unique Artificial Intelligence-based predictive model was developed for need for delayed surgery and probability of survival on medical therapy alone., Results: A total of 79 subjects were included in the study. Twenty eight (35.0 %) patients had type 2 diabetes mellitus. Subjects most commonly reported symptoms within the first week of the procedure (43 %). Fever was the most common initial symptom (72 %). Thirty eight percent of patients presented with acute coronary syndrome. The presence of mycotic aneurysms was described in 62 % of patients. Staphylococcus species were the most common (65 %) isolated organism. The primary outcome of in-hospital mortality was seen in a total of 24 patients out of 79 (30.3 %). A comparative univariate analysis comparing those encountering in-hospital mortality versus otherwise revealed the presence of structural heart disease (83 % mortality vs 17 % survival, p = 0.009), and the presence of non ST elevation acute coronary syndrome (11 % mortality vs 88 % survival, p = 0.03), to be a statistically significant factor predicting in-hospital mortality. In an analysis between patients with successful versus failed initial medical therapy, patients from private teaching hospitals (80.0 % vs 20.0 %; p = 0.01, n = 10) had a higher survival with medical therapy alone., Conclusion: CSI is a highly under-studied disease entity with largely unknown risk factors and clinical outcomes. Larger studies are needed to further define the characteristics of CSI.

Background: In TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention), among high-risk patients undergoing percutaneous coronary intervention (PCI), ticagrelor monotherapy vs continuation of dual antiplatelet therapy (DAPT) with aspirin and ticagrelor after completing a 3-month course of DAPT was associated with reduced bleeding, without an increase in ischemic events., Objectives: This investigation sought to study the clinical benefit of ticagrelor monotherapy vs DAPT by simultaneously modeling its associated potential bleeding benefits and ischemic harms on an individual patient basis., Methods: Multivariable Cox regression models for: 1) Bleeding Academic Research Consortium type 2, 3, or 5 (BARC-2/3/5); and 2) cardiovascular death, nonfatal myocardial infarction, and nonfatal ischemic stroke (major adverse cardiac and cerebrovascular event [MACCE]) were developed using stepwise forward variable selection. The coefficients in the BARC-2/3/5 and MACCE models were used to calculate bleeding and ischemic risk scores, respectively, for each patient (excluding the coefficient for randomized treatment)., Results: In the total study group (N = 7,119), BARC-2/3/5 occurred in 391 (5.5%) patients, and MACCE occurred in 258 (3.6%). There was a consistent reduction in bleeding events associated with ticagrelor monotherapy compared with DAPT across both bleeding and ischemic risk strata (P interaction = 0.54 and 0.11, respectively). Importantly, this benefit associated with ticagrelor monotherapy was not offset by an increase in MACCE at any level of bleeding or ischemic risk., Conclusions: Three months after PCI, discontinuing aspirin and maintaining ticagrelor monotherapy reduces bleeding in both higher-bleeding risk and lower-bleeding risk patients compared with continued DAPT. This benefit does not appear to be offset by greater ischemic risk.

There is limited data on new-generation stent outcomes in patients with previous coronary artery bypass graft (CABG) and the associated risk of gender and race/ethnicity is unclear. We investigated 1-year outcomes after platinum chromium everolimus-eluting stent implantation in a diverse population of men, women, and minorities with previous CABG pooled from the PLATINUM Diversity (NCT02240810) and PROMUS Element Plus (NCT01589978) registries. Our primary outcome was major adverse cardiac events (MACE), a composite of all-cause death, myocardial infarction (MI), and target vessel revascularization (TVR) at 1-year post percutaneous coronary intervention (PCI). Secondary end points included all-cause death, MI, TVR, target vessel failure, and stent thrombosis. A total of 4,175 patients were included in the analysis, including 1,858 women (44.5%), 1,057 minorities (25.3%), and 662 (15.9%) with previous CABG. Patients with previous CABG were older, included more men and White patients, and had more co-morbidities compared with patients without previous CABG. At 1 year, patients with previous CABG had a higher risk of MACE (12.6% vs 7.5%, hazard ratio 1.70, 95% confidence interval 1.32 to 2.19, p <0.001) and end points, including death/MI, TVR, and target vessel failure. After multivariate adjustment, no differences were observed in MACE (adjusted hazard ratio 1.11, 95% confidence interval 0.82 to 1.49, p = 0.506) or any secondary end points. No interaction was observed between previous CABG and gender or minority status. In conclusion, in a contemporary PCI population, patients with previous CABG remain at high risk for PCI because of their elevated risk profile. Previous CABG status was however not independently associated with worse outcomes after adjustment, nor was any interaction observed with gender or race/ethnicity., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest to declare., (Copyright © 2023 Elsevier Inc.

The burden of atherosclerotic cardiovascular disease contributes to a large proportion of morbidity and mortality, globally. Vaccination against atherosclerosis has been proposed for over 20 years targeting different mediators of atherothrombosis; however, these have not been adequately evaluated in human clinical trials to assess safety and efficacy. Inflammation is a driver of atherosclerosis, but inflammatory mediators are essential components of the immune response. Only pathogenic forms of sTNFR2 are acted upon while preserving the membrane-bound (wild-type) TNFR2 contributions to a non-pathogenic immune response. We hypothesize that the inhibition of sTNRF2 will be more specific and offer long-term treatment options. Here we describe pre-clinical findings of an sTNFR2-targeting peptide vaccine (AtheroVax™) in a mouse model. The multiple pathways to synthesis of the soluble TNFRII receptor (sTNFRII) were identified as sTNFRII(PC), sTNFRII(Δ7), and sTNFRII(Δ7,9). The sTNFRII(Δ7) peptide, NH2-DFALPVEKPLCLQR-COOH is specific to sTNFR2 based on an mRNA splice-variant in which exon 6 is joined to exon 8. The role of sTNFRII(Δ7) as a mediator of prolonged TNFα activity by preventing degradation and clearance was investigated. Inflammation is a critical driver of onset, progression and expansion of atherosclerosis. The TNFα ligand represents a driver of inflammation that is mediated by a splice variant of TNFR2, referred to as sTNFRII(Δ7). The multiple forms of TNFRII, both membrane bound and soluble, are associated with distinctly different phenotypes. sTNFRII(PC) and sTNFRII(Δ7) are not equivalent to etanercept because they lack a clearance mechanism. The unique peptide associated with sTNFRII(Δ7) contains a linear B-cell epitope with amino acids from both exon 6 and exon 8 supporting the vaccine design. Animal studies to evaluate the vaccine are ongoing, and results will be forthcoming. We describe a peptide vaccine targeting sTNFR2 in limiting the progression of atherosclerosis. A therapeutic vaccine limiting the progression of atherosclerosis will greatly contribute to the reduction in morbidity and mortality from cardiovascular disease. It is likely the vaccine will be used in combination with the current standards of care and lifestyle modifications., Competing Interests: The authors PI, NiK, and NoK all are co-inventors of the AtheroVax vaccine and share interest in commercial development of the vaccine. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Iversen, Kipshidze, Kipshidze, Dangas, Ramacciotti, Kakabadze and Fareed.)

Aim: The aim of this study was to assess the effect of ticagrelor monotherapy among high-risk patients with anaemia undergoing percutaneous coronary intervention (PCI)., Methods and Results: In the TWILIGHT (Ticagrelor with Aspirin or Alone in High-Risk Patients after Coronary Intervention) trial, after 3 months of ticagrelor plus aspirin, high-risk patients were maintained on ticagrelor and randomized to aspirin or placebo for 1 year. Anaemia was defined as haemoglobin <13 g/dL for men and <12 g/dL for women. The primary endpoint was Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding. The key secondary endpoint was a composite of all-cause death, myocardial infarction, or stroke.Out of 6828 patients, 1329 (19.5%) had anaemia and were more likely to have comorbidities, multivessel disease, and to experience bleeding or ischaemic complications than non-anaemic patients. Among anaemic patients, BARC 2, 3, or 5 bleeding occurred less frequently with ticagrelor monotherapy than with ticagrelor plus aspirin [6.4% vs. 10.7%; hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.41-0.88; P = 0.009]; the rate of the key secondary endpoint was similar in the two arms (5.2% vs. 4.8%; HR 1.07; 95% CI 0.66-1.74; P = 0.779). These effects were consistent in patients without anaemia (interaction P values 0.671 and 0.835, respectively)., Conclusion: In high-risk patients undergoing PCI, ticagrelor monotherapy after 3 months of ticagrelor-based dual antiplatelet therapy was associated with a reduced risk of clinically relevant bleeding without any increase in ischaemic events irrespective of anaemia status (TWILIGHT: NCT02270242)., (© The Author(s) 2023.
