Background It is unknown whether contemporary drug-eluting stents have a similar safety profile in high bleeding risk patients treated with 1-month dual antiplatelet therapy following percutaneous coronary interventions. Methods and Results We performed an interventional, prospective, multicenter, single-arm trial, powered for noninferiority with respect to an objective performance criterion to evaluate the safety of percutaneous coronary interventions with Synergy bioresorbable-polymer everolimus-eluting stent followed by 1-month dual antiplatelet therapy in patients with high bleeding risk. In case of need for an oral anticoagulant, patients received an oral anticoagulant in addition to a P2Y 12 inhibitor for 1 month, followed by an oral anticoagulant only. The primary end point was the composite of cardiac death, myocardial infarction, or definite or probable stent thrombosis at 1-year follow-up. The study was prematurely interrupted because of slow recruitment. From April 2017 to October 2019, 443 patients (age, 74.8±9.2 years; women, 29.1%) at 10 Italian centers were included. The 1-year primary outcome occurred in 4.82% (95% CI, 3.17%-7.31%) of patients, meeting the noninferiority compared with the predefined objective performance criterion of 9.4% and the noninferiority margin of 3.85% ( P noninferiority <0.001) notwithstanding the lower-than-expected sample size. The rates of cardiac death, myocardial infarction, and definite or probable stent thrombosis were 1.88% (95% CI, 0.36%-2.50%), 3.42% (95% CI, 2.08%-5.62%), and 0.94% (95% CI, 0.35%-2.49%), respectively. Conclusions Among high bleeding risk patients undergoing percutaneous coronary interventions with the Synergy bioresorbable-polymer everolimus-eluting stent, a 1-month dual antiplatelet therapy regimen is safe, with low rates of ischemic and bleeding events.

Aims: The aim of this study was to evaluate the safety and efficacy profile of new-generation, SYNERGY everolimus-eluting stents (S-EES) as compared to XIENCE everolimus-eluting stents (X-EES) with a durable polymer coating in "complex patients"., Methods and Results: We included 2,001 consecutive patients treated with S-EES (n=400) or X-EES (n=1,601) at two Italian centres between May 2013 and May 2015. We used propensity score matching to obtain two cohorts of patients with similar baseline risk profiles. Patients were stratified according to baseline complexity based on the EVOLVE II trial exclusion criteria. The primary outcome was major adverse cardiac events (MACE), defined as the composite of all-cause death, myocardial infarction (MI), and target lesion revascularisation (TLR), at one year. Among 391 matched pairs of patients treated with S-EES or X-EES, we identified 253 (63%) as complex. At one-year follow-up, among "complex" patients, MACE rates did not differ between the S-EES and X-EES groups (9.9% vs. 9.5%, p=0.830, HR 1.04, CI: 0.72-1.48). Similarly, death, MI, and TLR, stratified for complexity, were comparable between S-EES and X-EES treated patients at one year. Of note, no definite ST was observed in either the S-EES or the X-EES cohort., Conclusions: New-generation S-EES with a bioresorbable polymer coating appear to be safe and effective irrespective of patient complexity as compared to X-EES.

Background: The aim of this study was to assess the impact of bivalirudin, as compared to unfractionated heparin, on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI)., Methods: A meta-analysis of randomized trials comparing bivalirudin versus heparin in patients with STEMI undergoing primary percutaneous coronary intervention was performed. Three randomised trials enrolling 7,612 patients were included. Analysis was by intention to treat., Results: At 30 days, bivalirudin, as compared to heparin, was associated with a similar risk of all-cause mortality (3.03% vs. 3.38%, odds ratio (OR) 0.90, 95% confidence intervals (CI) [0.63 to 1.29], P = 0.57). Bivalirudin significantly increased the risk of definite (2.39% vs. 1.06%, OR 2.49, 95% CI [1.30 to 4.76], P = 0.006); definite or probable (2.55% vs. 1.35%, OR 2.26, 95% CI [1.07 to 4.79], P = 0.03), and acute stent thrombosis (1.69% vs. 0.39%, OR 4.34, 95% CI [2.30 to 8.16], P < 0.001); leading to nonsignificantly higher reinfarction rates (2.0% vs. 1.31%, OR 1.72, 95% CI [0.89 to 3.35], P = 0.11), and to a significantly increased risk of ischemia driven revascularization (2.50% vs. 1.52%, OR 1.80, 95% CI [1.02 to 3.18], P = 0.04) at 30 days. No firm evidence for a reduction in major bleeding associated with bivalirudin use was found (3.93% vs. 6.39%, OR 0.63, 95% CI [0.39 to 1.04], P = 0.07)., Conclusions: In patients with STEMI, bivalirudin, as compared to heparin, increases the risk of stent thrombosis and ischemia driven repeat revascularization at 30 days. There is no strong evidence that bivalirudin significantly reduces major bleeding at 30 days. Bivalirudin does not have an effect on all-cause mortality at 30 days., (© 2015 Wiley Periodicals, Inc.)

Aims: Contrast-induced nephropathy (CIN) and periprocedural myocardial infarction (PMI) represent frequent complications of percutaneous coronary intervention (PCI) and negatively impact subsequent length of hospitalization, costs of adjunctive diagnostic-therapeutic measures and mid-term cardiovascular events. The aim of the EURO-CRIPS trial is to test whether remote ischemic preconditioning (RIPC) may reduce the incidence of these complications and improve mid-term outcome., Methods: This will be a double-blind, randomized, placebo-controlled multicentre study. Patients will be allocated 1 : 1 to RIPC or standard therapy if they were younger than 85 years old, with a renal clearance in the interval 30-60 ml/min/1.73 m and candidate to PCI for all clinical indications except for primary PCI in ST segment elevation myocardial infarction (STEMI), unstable haemodynamic presentations or ongoing severe arrhythmias. Incidence of CIN will be the primary end point and the amount of periprocedural cardiac enzyme leakage will be the secondary end point. In addition, we will evaluate whether the preconditioned patients will have a reduction of MACCE at 6 months (major adverse cardiac and cerebrovascular event)., Conclusion: The EURO-CRIPS Study will be the first large-scale, multicentre clinical trial to test the role of RIPC in current clinical practice. The results of this randomized trial will provide important insights to optimize management strategy of patients undergoing PCI and to improve their outcome.

Objectives: INSPIRE-1 (Italian Nobori Stent ProspectIve REgistry-1) was designed and conducted to assess clinical performance of Nobori biolimus A9-eluting stent (BES) implantation in an unrestricted "real-world" cohort of patients., Methods: Unrestricted consecutive high-risk patients treated with BES with biodegradable polymer (Nobori, Terumo, Tokyo, Japan) between February 2008 and July 2012 were prospectively enrolled in an independent multicenter registry and divided in two groups: complex and non complex lesions., Results: 1066 patients (1589 lesions) treated with Nobori BES were analyzed. The majority of patients (57%) were treated for at least one complex lesion and presented a high-risk clinical profile (previous CABG 17.6%, diabetes mellitus 33.1%, chronic kidney disease 14.3%). Angiographic success rate was achieved in 96.2% cases. At 1 year, the primary endpoint, (composite of cardiac death, myocardial infarction, and clinically driven target vessel revascularization), occurred in 39 (4.0%) patients, and was higher in the complex lesions (5.2% vs. 2.5%, P = 0.032). Target lesion failure (TLF, secondary endpoint) occurred in 45 (4.6%) patients, and was more frequent in the complex lesions group (6.2% vs. 2.7%, P = 0.011), mainly due to a higher incidence of any target lesion revascularization (4.8% vs. 2.7%; P = 0.095). Definite and probable stent thrombosis (ST) rate was 0.6% and 0.5% respectively, with no difference between groups., Conclusions: In unrestricted daily practice, BESs were implanted predominantly in high risk patients with complex lesions. Despite this, the Nobori BES was associated with a relatively low rate of primary endpoint and TLF, with a higher risk in patients with complex lesions., (Copyright © 2014 Elsevier Ireland Ltd.

The aim of this study was to assess recent trends in hospital mortality and in the treatment techniques for patients with ST-segment elevation myocardial infarction according to gender. Data on hospitalizations for ST-segment elevation myocardial infarction from 2000 to 2010 were extracted from hospital discharge record databases (International Classification of Diseases, Ninth Revision, Clinical Modification, codes) in the Lombardy Region of Italy. The impact of female gender on in-hospital mortality was assessed by multivariable regression after adjusting for invasive approach use (i.e., coronary angiography, angioplasty or coronary artery bypass graft), age, and co-morbidities. A total of 89,562 patients, men (66.5%) and women (33.5%), were enrolled. The use of an invasive approach increased over time in both sexes although it was higher in men (from 54.9% in 2000 to 91.9% in 2010 in men; from 36.8% in 2000 to 72.0% in 2010 in women). This pattern was driven by the subgroup of patients aged ≥75 years, whereas differences between sexes were not observed in patients <65 years and were small in patients aged 65 to 74 years. In-hospital mortality presented a small decrease from 7.6% in 2000 to 6.2% in 2010 in men (p for trend = 0.004), whereas it remained higher and substantially constant over time in women (16.6% in 2000, 15.5% in 2010, p for trend = 0.09). At multivariable regression, female gender did not emerge as an independent predictor of mortality (p = 0.13). However, a significant gender-age interaction was found, with female gender being a significant predictor of increased mortality in patients aged ≥75 years (odds ratio [OR] 1.33) while predicting a reduced mortality in patients aged <75 years (OR 0.93, p for interaction <0.0001). The use of an invasive approach was an independent predictor of mortality (OR 0.23, p <0.0001), the magnitude of mortality reduction being higher in men than in women and in patients aged <75 years than in those aged ≥75 years. In conclusion, a weak temporal trend in mortality reduction is observed in men only, which is driven by patients aged ≥75 years. In-hospital mortality remains higher in women than in men, although female gender is not a significant predictor of mortality. Despite temporal increases in the use of an invasive approach, women are more often treated conservatively., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Objectives: We assessed the relation between female sex and sirolimus-eluting stent (SES) use on long-term outcomes in acute myocardial infarction., Background: There are no data on sex-specific differences in long-term benefit of SES use compared with bare-metal stent (BMS) use among patients undergoing primary percutaneous coronary interventions., Methods: We performed a post hoc analysis of the MULTISTRATEGY trial. Hazard ratios (HRs) of events with 95% CI for sex and stent type were computed using Cox proportional regression with adjustment for confounders., Results: A total of 744 patients, 64 years old (55-73 years old), 179 (24.1%) women, were enrolled. After a follow-up of 1,080 days, SES use was associated with a significant reduction of major adverse cardiovascular events, that is, the composite of all-cause death, reinfarction, or clinically driven target vessel revascularization (TVR) (13.9% vs 23.6%, adjusted HR 0.62, 95% CI 0.41-0.94, P = .026) and of TVR (6.1% vs 15.1%, adjusted HR 0.35, 95% CI 0.19-0.63, P < .001) in men. Conversely, SES use was not associated to a better outcome among women (major adverse cardiovascular events 21.9% in SES vs 18.2% in the BMS group, adjusted HR 1.27, 95% CI 0.53-3.02, P = .59; TVR 6.6% vs 9.1%, adjusted HR 0.62, 95% CI 0.17-2.21, P = .46)., Conclusions: In this analysis, the clinical benefit of SES use, over BMS, at 3-year follow-up was restricted to men and was not observed among women., (Copyright © 2012 Mosby, Inc.

PTX3 is a long pentraxin of the innate immune system produced by different cell types (mononuclear phagocytes, dendritic cells, fibroblasts and endothelial cells) at the inflammatory site. It appears to have a cardiovascular protective function by acting on the immune-inflammatory balance in the cardiovascular system. PTX3 plasma concentration is an independent predictor of mortality in patients with acute myocardial infarction (AMI) but the influence of PTX3 genetic variants on PTX3 plasma concentration has been investigated very little and there is no information on the association between PTX3 variations and AMI. Subjects of European origin (3245, 1751 AMI survivors and 1494 controls) were genotyped for three common PTX3 polymorphisms (SNPs) (rs2305619, rs3816527, rs1840680). Genotype and allele frequencies of the three SNPs and the haplotype frequencies were compared for the two groups. None of the genotypes, alleles or haplotypes were significantly associated with the risk of AMI. However, analysis adjusted for age and sex indicated that the three PTX3 SNPs and the corresponding haplotypes were significantly associated with different PTX3 plasma levels. There was also a significant association between PTX3 plasma concentrations and the risk of all-cause mortality at three years in AMI patients (OR 1.10, 95% CI: 1.01-1.20, p = 0.02). Our study showed that PTX3 plasma levels are influenced by three PTX3 polymorphisms. Genetically determined high PTX3 levels do not influence the risk of AMI, suggesting that the PTX3 concentration itself is unlikely to be even a modest causal factor for AMI. Analysis also confirmed that PTX3 is a prognostic marker after AMI.

Background: Conflicting information exists about whether sex differences affect long-term outcomes in patients undergoing primary percutaneous coronary intervention (PCI)., Methods: This retrospective study enrolled consecutive patients with ST-elevation myocardial infarction undergoing primary PCI within 24 hours from symptom onset. Hazard ratios (HRs) of events with 95% confidence interval (CI) were calculated in the overall population and in a propensity score matched cohort of women and men., Results: Among 481 patients, median age 66 years old, 138 (28.7%) were women. Women were older than men (72 vs 63 years, P<0.001), had a higher prevalence of hypertension (68% vs 54%, P=0.006), diabetes (27% vs 19%, P=0.04), and Killip class≥3 at admission (19% vs 10%, P=0.007). After a median follow-up of 1041 days women experienced a significant higher incidence of the composite of death, nonfatal myocardial infarction, and hospitalization for heart failure (31.9% vs 18.4%, unadjusted HR 1.86; 95% CI, 1.26-2.74; P=0.002), driven mainly by heart failure (unadjusted HR 2.47; 95% CI, 1.12-5.41; P=0.024), without significant differences in death (unadjusted HR 1.49; 95% CI, 0.88-2.53; P=0.13), or nonfatal myocardial infarction (unadjusted HR 1.59; 95% CI, 0.78-3.27; P=0.19) and no increase in target lesion revascularization (9.4% vs 12.5%, unadjusted HR 0.77; 95% CI, 0.42-1.44; P=0.42). After propensity score matching the hazard of the composite endpoint was largely attenuated (HR 1.32; 95% CI, 0.84-2.06; P=0.23)., Conclusions: Women undergoing primary PCI experience worse long-term outcomes than men, but this difference is largely explained by their more adverse baseline cardiovascular profile., (Copyright © 2011 Canadian Cardiovascular Society.

Prior studies have reported significant gender differences in the procedural outcomes after elective percutaneous transluminal coronary angioplasty (PTCA). Many of these differences have been explained by the presence of more comorbidities and worse clinical characteristics such as older age, unstable angina, congestive heart failure, diabetes mellitus, and hypertension in women than in men. Moreover, women have a smaller vessel diameter, more coronary tortuosity and different plaque composition compared to men that can lead to a higher dissection rate and a greater number of procedural complications. Although early data on PTCA suggested worse immediate results in women than in men, more recent data suggest that this difference is less marked. The introduction of stents with a low profile and a higher tractability and pushability has allowed the extensive application of these devices even in small and tortuous vessels improving the outcome of PTCA. This improvement has been higher in women than in men leading to the equalization of the immediate outcome in the two sexes, even if the baseline characteristics remain worse in women. In particular, mortality and the need for urgent surgical revascularization have become extremely low without any differences between sexes. However, some authors have still found a higher incidence of complications in the first period after the procedure due to stent thrombosis in the stenting era. For this reason, meticulous antiplatelet treatment should be prescribed and drugs such as glycoprotein IIb/IIIa inhibitors may also be considered advisable to reduce the excess risk in the female population particularly in women with prothrombotic risk factors such as diabetes. At 6 and 12 months similar rates of death, late myocardial infarction, and repeated revascularization have been shown in the two sexes. Coronary stenting and the use of glycoprotein IIb/IIIa inhibitors have also improved the immediate results in patients with acute myocardial infarction (AMI) undergoing primary PTCA. Studies comparing the outcome differences between women and men with AMI and treated with primary PTCA are limited but all suggest that women benefit more than men from this procedure. The in-hospital mortality in patients with AMI is significantly higher in the female than in the male population with a higher incidence of intracranial hemorrhage in women among tissue-type plasminogen activator-treated patients. Vice versa, women and men have a similar or a slightly higher in-hospital mortality after primary PTCA without intracranial bleeding complications. For this reason, an earlier diagnosis of AMI, an earlier hospital admission and an earlier primary PTCA should be the aims of management in order to improve the outcome in women with AMI and to equalize the procedural results in the two sexes.

There are important dissimilarities in clinical presentation, aggregation of comorbidities, cardiovascular risk factors and the quality of delivery of medical care among men and women with acute coronary syndrome (ACS). Compared with men, despite the well-known older age and more pronounced frailty, women with ACS present later from symptom onset and are at high bleeding risk after invasive procedures. In addition, autoimmune/inflammatory disease, fibromuscular dysplasia, polycystic ovary, early menopause and history of pre-eclampsia are risk factors preceding ACS among younger women. They more often experience myocardial infarction in the absence of obstructive coronary arteries (MINOCA), which makes diagnosis and treatment of ACS among women more challenging compared with men. Women and men do both benefit from guideline-recommended treatment, although, compared with men, women with ACS have a higher adjusted risk of early death, which equalises between both sexes within the first year. Young women with ACS suffer frequently of depression and present often with MINOCA. Compared with young men, they (young women) have a higher risk of death. Therefore, focusing on young patients with ACS, understanding the particular physiopathology of MINOCA and developing programmes targeting comorbidities and depression-related behavioural risk factors are urgently needed.

Transcatheter aortic valve implantation (TAVI) has become an accepted treatment for patients with severe aortic stenosis (AS). Predicting which patients are at risk for adverse clinical outcomes after TAVI remains difficult, especially in women. To identify predictors of adverse events in the WIN-TAVI cohort. The WIN-TAVI study is an observational registry of 1019 women undergoing TAVI for severe symptomatic AS. Follow-up was 1 year. The primary outcome was defined according to VARC-2: a composite of mortality, stroke, myocardial infarction or hospitalization for valve-related symptoms or heart failure. The secondary outcome was a composite of cardiovascular mortality or hospitalization for valve-related symptoms or heart failure. We included 1019 women with severe AS (mean age of 82.5 ± 6.3 years). At 1 year, 16.4% of the patients experienced the primary endpoint and 12.6% the secondary endpoint. The use of oral anticoagulants (OAC) was the strongest independent predictor of the primary outcome (adjusted hazard ratio [aHR] 1.51, 95% confidence interval [CI] 1.079–2.106, p = 0.016). Independent predictors of the secondary endpoint were age (aHR 1.04 per year, 95% CI 1.01–1.074, p = 0.016) and use of OAC (aHR: 1.79, 95% CI 1.24–2.60, p = 0.002). OAC use was not associated with higher bleeding risk. Pre-procedural use of OAC was the strongest predictor of adverse outcomes during 1-year follow-up, likely reflecting a combination of high-risk factors and comorbidities, but was not related to increased bleeding risk. • Predicting adverse outcomes in women after TAVI is challenging. • Use of oral anticoagulant (OAC) was the strongest predictor of adverse outcomes. • OAC use may reflect a combination of high-risk factors and comorbidities. • OAC use may be included in risk assessment after TAVI not only for bleeding.

Background It is unclear whether radial compared with femoral access improves outcomes in unselected patients with acute coronary syndromes undergoing invasive management. Methods We did a randomised, multicentre, superiority trial comparing transradial against transfemoral access in patients with acute coronary syndrome with or without ST-segment elevation myocardial infarction who were about to undergo coronary angiography and percutaneous coronary intervention. Patients were randomly allocated (1:1) to radial or femoral access with a web-based system. The randomisation sequence was computer generated, blocked, and stratified by use of ticagrelor or prasugrel, type of acute coronary syndrome (ST-segment elevation myocardial infarction, troponin positive or negative, non-ST-segment elevation acute coronary syndrome), and anticipated use of immediate percutaneous coronary intervention. Outcome assessors were masked to treatment allocation. The 30-day coprimary outcomes were major adverse cardiovascular events, defined as death, myocardial infarction, or stroke, and net adverse clinical events, defined as major adverse cardiovascular events or Bleeding Academic Research Consortium (BARC) major bleeding unrelated to coronary artery bypass graft surgery. The analysis was by intention to treat. The two-sided α was prespecified at 0·025. The trial is registered at ClinicalTrials.gov, number NCT01433627. Findings We randomly assigned 8404 patients with acute coronary syndrome, with or without ST-segment elevation, to radial (4197) or femoral (4207) access for coronary angiography and percutaneous coronary intervention. 369 (8·8%) patients with radial access had major adverse cardiovascular events, compared with 429 (10·3%) patients with femoral access (rate ratio [RR] 0·85, 95% CI 0·74–0·99; p=0·0307), non-significant at α of 0·025. 410 (9·8%) patients with radial access had net adverse clinical events compared with 486 (11·7%) patients with femoral access (0·83, 95% CI 0·73–0·96; p=0·0092). The difference was driven by BARC major bleeding unrelated to coronary artery bypass graft surgery (1·6% vs 2·3%, RR 0·67, 95% CI 0·49–0·92; p=0·013) and all-cause mortality (1·6% vs 2·2%, RR 0·72, 95% CI 0·53–0·99; p=0·045). Interpretation In patients with acute coronary syndrome undergoing invasive management, radial as compared with femoral access reduces net adverse clinical events, through a reduction in major bleeding and all-cause mortality.

Background The optimal duration of dual antiplatelet therapy (DAPT) following second-generation drug-eluting stent (DES) implantation is still debated. Objectives The aim of this study was to test the noninferiority of 6 versus 12 months of DAPT in patients undergoing percutaneous coronary intervention with second-generation DES. Methods The SECURITY (Second Generation Drug-Eluting Stent Implantation Followed by Six- Versus Twelve-Month Dual Antiplatelet Therapy) trial was a 1:1 randomized, multicenter, international, investigator-driven, noninferiority study conducted from July 2009 to June 2014. Patients with a stable or unstable angina diagnosis or documented silent ischemia undergoing revascularization with at least 1 second-generation DES were eligible. The primary endpoint was a composite of cardiac death, myocardial infarction (MI), stroke, definite or probable stent thrombosis, or Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding at 12 months. The main secondary endpoint was a composite of cardiac death, MI, stroke, definite or probable stent thrombosis, or BARC type 2, 3, or 5 bleeding at 12 and 24 months. Results Overall, 1,399 patients were enrolled in the study and randomized to receive 6 months (n = 682) versus 12 months (n = 717) DAPT. The primary composite endpoint occurred, respectively, in 4.5% versus 3.7% (risk difference 0.8%; 95% confidence interval [CI]: −2.4% to 1.7%; p = 0.469) at 12 months. The upper 95% CI limit was lower than the pre-set margin of 2%, confirming the noninferiority hypothesis (p < 0.05). Moreover, no differences were observed in the occurrence of the secondary endpoint at 12 months (5.3% vs. 4.0%, difference: 1.2%; 95% CI: −1.0 to 3.4; p = 0.273) and between 12 and 24 months (1.5% vs. 2.2%, difference: −0.7%; 95% CI: −2.1 to 0.6; p = 0.289). Finally, no differences were observed in definite or probable stent thrombosis at 12 months (0.3% vs. 0.4%; difference: −0.1%; 95% CI: −0.7 to 0.4; p = 0.694) and between 12 and 24 months of follow-up (0.1% vs. 0%; difference: 0.1%; 95% CI: −0.1 to 0.4; p = 0.305). Conclusions In a low-risk population, the noninferiority hypothesis of 6 vs. 12 months DAPT following second-generation DES implantation appears accepted for the incidence of cardiac death, MI, stroke, definite/probable stent thrombosis, and BARC type 3 or 5 bleeding at 12 months.

Several clinical and procedural factors have been identified as predictors of early and midterm events after transcatheter aortic valve implantation (TAVI), but incidence and prognostic impact of diabetes mellitus (DM), especially insulin treated, on short- and midterm outcomes remain to be defined. All consecutive patients who underwent TAVI at our institutions were enrolled and stratified according to DM status. All-cause mortality at 30 days or in hospital and at follow-up was the primary end point, whereas periprocedural complications, rates of myocardial infarction, stroke, and reintervention at follow-up were the secondary ones. All end points were adjudicated according to the Valve Academic Research Consortium definitions. In all, 511 patients were enrolled: 361 without DM, 78 with orally treated DM, and 72 with insulin-treated DM. Orally treated DM patients were more frequently women, whereas insulin-treated DM patients were younger. Thirty-day Valve Academic Research Consortium mortality was not significantly higher in patients with orally treated DM and insulin-treated DM compared with patients without diabetes (6.4%, 9.7%, and 4.7%, p = 0.09). Bleedings, vascular complications, postprocedural acute kidney injury, and periprocedural strokes were not significantly different in the 3 groups. At midterm follow-up (median 400 days), patients with insulin-treated DM had a significantly higher mortality rate (33.3% vs 18.6%, p = 0.01) and higher myocardial infarction incidence (8.3% vs 1.4%, p = 0.002) if compared with patients without diabetes. Strokes and reinterventions at follow-up were similar in the 3 groups. After multivariable adjustment, insulin-treated DM was independently correlated with death (hazard ratio 2, 95% confidence interval 1.3 to 3.3) and myocardial infarction (hazard ratio 3.73, 95% confidence interval 1.1 to 13). In conclusion, DM does not significantly affect rates of complications in patients who underwent TAVI. Insulin-treated DM, but not orally treated DM, is independently associated with death and myocardial infarction at midterm follow-up and should be included into future TAVI-dedicated scores.
