Background: To date, the relationship between the Transesophageal Echocardiography (TEE) monitoring indicator tricuspid annular plane systolic excursion (TAPSE) and the incidence of postoperative acute kidney injury (AKI) in Coronary Artery Bypass Grafting(CABG) patients remains unknown. The main objective of this study was to explore the relationship between the TAPSE and the incidence of AKI in CABG patients. Methods: This was a multicenter prospective cohort study was conducted between September 2021 and July 2022. Among 266 patients aged at least 18 years who underwent elective CABG, 140 were included. Results: We measured TAPSE via M-mode TEE via the mid-esophageal (ME) right ventricle(RV) inflow-outflow view (60°). All echocardiographic measurements were performed three separate times at each time point: T0 (before the start of CABG), T2 (approximately 5 ∼ 10 min after neutralization of protamine) and T3 (before leaving the operating room), and then averaged. Serum creatinine was measured 1 day before and within 7 days after CABG. There was no statistically significant association between the TEE-monitoring indicator TAPSE and the incidence of postoperative AKI in patients who underwent CABG. Conclusions: The TAPSE was not significantly correlated with postoperative AKI incidence and could not predict the early occurrence of postoperative AKI in CABG patients. TEE needs more evaluation for clinical efficacy of predicting the early occurrence of postoperative AKI in isolated CABG. [ABSTRACT FROM AUTHOR]

Background: Coronary artery bypass grafting (CABG) surgery is a common procedure for managing multi-vessel coronary artery disease to revascularize the myocardium. Among the various conduits used, the left internal mammary artery (LIMA) is preferred due to its better long-term patency rate. However, CABG procedures involving LIMA may result in rare but serious complications, such as avulsion of the LIMA post-CABG, which leads to disruption of blood flow to the myocardium and the development of fatal cardiac tamponade. Case presentation: We hereby present a unique case of spontaneous avulsion of a LIMA graft to the left anterior descending artery (LAD) away from the site of anastomosis, twenty-four hours following CABG surgery in a 67-year-old male patient. Emergency re-exploration and repair of the LIMA with interposition vein graft were performed and resulted in successful stabilization of the patient's critical condition. However, this was followed by a complicated recovery period involving atrial fibrillation, acute kidney injury, and wound infection. Conclusion: Avulsion of LIMA graft following CABG is rare, yet a fatal complication that requires high clinical suspicion and prompt management. Avulsion has been reported a few times in literature following both minimal invasive and conventional CABG. Understanding the etiology, clinical presentation, and management of this complication is crucial to avoid catastrophic outcomes. [ABSTRACT FROM AUTHOR]

HORNER syndrome , *CORONARY artery bypass , *RIB fractures , *LITERATURE reviews , *INTERNAL thoracic artery , *STELLATE ganglion - Abstract
Background: Horner's syndrome is a rare complication of cardiovascular surgery. A bone fragment and hematoma due to rib fracture after cardiac surgery may cause injury to the brachial nerve plexus and sympathetic nerve trunk, leading to neurologic disorders and Horner's syndrome. However, few reports have revealed the etiology of Horner's syndrome after cardiovascular surgery based on imaging. Herein we present a case in which a plain CT scan confirmed the etiology of Horner's syndrome after coronary artery bypass grafting (CABG), reviewing 139 CABG cases retrospectively in our hospital and 6 case reports of Horner's syndrome associated with cardiovascular surgery. Case presentation: A 69-year-old woman with a history of percutaneous coronary intervention and total abdominal hysterectomy with bilateral salpingo-oophorectomy had chest pain on exertion. Coronary angiography showed severe triple vessel disease. She underwent off-pump coronary artery bypass grafting (CABG). A median sternotomy was performed, and the split sternums were widened using a sternal retractor. The bilateral internal thoracic arteries were harvested. A triple CABG was performed. She had left shoulder pain after surgery. She complained of anhidrosis involving the left face and hyperhidrosis involving the right face from postoperative day (POD) 6. Left ptosis and blurry vision appeared after discharge from the hospital, for which she saw a neurologist in our hospital on POD 48. Miosis could not be clearly confirmed. She was diagnosed with Horner's syndrome. A plain CT scan revealed displaced fractures of the bilateral first ribs and left second rib. The bone fragment of the left first rib head was displaced 3 mm anteriorly compared to the left first rib head before surgery, which suggested that the fragment affected the stellate ganglion in the sympathetic trunk. The patient had regular follow-up evaluations. The anhidrosis persisted, but the ptosis improved, and the miosis was not confirmed at the 6-month follow-up evaluation. Conclusions: We should recognize that Horner's syndrome is one of the complications of cardiovascular surgery, especially CABG. Fracture of the first rib head with a displaced bone fracture was shown to be a contributor to ipsilateral Horner's syndrome. When symptoms of Horner's syndrome and other neurologic symptoms are noted after open heart surgery, a plain CT examination should be obtained. [ABSTRACT FROM AUTHOR]

Reoperation for bleeding (ROB) after emergency coronary artery bypass grafting (eCABG) has been identified as an independent risk factor for mortality. Consecutively, the influence of fluid intake, fluid output, fluid balance, blood loss, and inotropic demand on ROB were analyzed. This retrospective single-center study included 265 patients undergoing eCABG between 2011 and 2020. From 2018, postoperative hemodynamic management was performed with lower volume administration and higher vasoactive support. The primary outcome measure was the incidence of ROB within 48 h according to altered fluid resuscitation strategy. Consecutively, the influence of fluid intake, fluid output, fluid balance, blood loss, and inotropic demand on ROB were analyzed. Incidence of ROB was independent from the volume resuscitation protocol (P =.3). The ROB group had a higher perioperative risk, which was observed in EuroSCORE II. Fluid intake (P =.021), fluid balance (P =.001), and norepinephrine administration (P =.004) were associated with ROB. Fluid output and blood loss were not associated with ROB (P =.22). Post-test probability was low among all variables. Although fluid management might have an impact on specific postoperative complications, different fluid resuscitation protocols did not alter the incidence of ROB after emergency CABG. Trial registration: www.clinicaltrials.gov registration number NCT04533698; date of registration: August 31, 2020 (retrospectively registered due to nature of the study); URL: https://classic.clinicaltrials.gov/ct2/show/NCT04533698 [ABSTRACT FROM AUTHOR]

Introduction: Stroke is a potentially debilitating complication of heart valve replacement surgery, with rates ranging from 1 to 10%. Despite advancements in surgical techniques, the incidence of postoperative stroke remains a significant concern, impacting patient outcomes and healthcare resources. This study aims to investigate the incidence, risk factors, and outcomes of in-hospital adverse neurologic events, particularly stroke, following valve replacement. The analysis focuses on identifying patient characteristics and procedural factors associated with increased stroke risk. Methods: This retrospective study involves a review of 417 consecutive patients who underwent SVR between January 2004 and December 2022. The study cohort was extracted from a prospectively recorded cardiac intensive care unit database. Preoperative and perioperative data were collected, and subjects with specific exclusion criteria were omitted from the analysis. The analysis includes demographic information, preoperative risk factors, and perioperative variables. Results: The study identified a 4.3% incidence of postoperative stroke among SVR patients. Risk factors associated with increased stroke susceptibility included prolonged cardiopulmonary bypass time, aortic cross-clamp duration exceeding 90 min, prior stroke history, diabetes mellitus, and mitral valve annulus calcification. Patients undergoing combined procedures, such as aortic valve replacement with mitral valve replacement or coronary artery bypass grafting with AVR and MVR, (OR = 10.74, CI:2.65–43.44, p-value = < 0.001) and (OR = 11.66, CI:1.02–132.70, p-value = 0.048) respectively, exhibited elevated risks. Internal carotid artery stenosis (< 75%) and requiring prolonged inotropic support were also associated with increased stroke risk(OR = 3.04, CI:1.13–8.12, P-value = 0.026). The occurrence of stroke correlated with extended intensive care unit stay (OR = 1.12, CI: 1.04–1.20, P-value = 0.002) and heightened in-hospital mortality. Conclusion: In conclusion, our study identifies key risk factors and underscores the importance of proactive measures to reduce postoperative stroke incidence in surgical valve replacement patients.

SEX factors in disease , *CORONARY artery bypass , *WOMEN'S mortality , *SAPHENOUS vein ,MORTALITY risk factors - Abstract
There are controversies regarding the impact of sex on mortality and postoperative complications in patients undergoing on-pump coronary artery bypass grafting (CABG), although some studies demonstrate comparable outcomes. This study sought to evaluate sex differences regarding risk factors associated with hospital mortality and postoperative clinical outcomes among patients undergoing isolated on-pump CABG. We conducted a retrospective observational cohort study of patients who underwent isolated on-pump CABG from January 1996 to January 2020. Patients were divided into two groups (male and female) and compared regarding preoperative characteristics, surgical technical variables, and in-hospital outcomes. All-cause mortality between groups was compared using logistic regression. Risk factors for mortality, along with their respective odds ratios (OR), were separately assessed using a logistic regression model with p-values for interaction. We analyzed 4,882 patients, of whom 31.6% were female. Women exhibited a higher prevalence of age >75 years (12.2% vs 8.3%, p<0.001), obesity (22.6% vs 11.5%, p<0.001), diabetes (41.6% vs 32.2%, p<0.001), hypertension (85.2% vs 73.5%, p<0.001), and NYHA functional classes 3 and 4 (16.2% vs 11.2%, p<0.001) compared to men. Use of the mammary artery for revascularization was less frequent among women (73.8% vs 79.9%, p<0.001), who also received fewer saphenous vein grafts (2.17 vs 2.27, p = 0.002). A history of previous or recent myocardial infarction (MI) had an impact on women's mortality, unlike in men (OR 1.61 vs 0.94, p = 0.014; OR 1.86 vs 0.99, p = 0.015, respectively). After adjusting for several risk factors, mortality was found to be comparable between men and women, with an OR of 1.20 (95% CI 0.94–1.53, p = 0.129). In conclusion, female patients undergoing isolated on-pump CABG presented with a higher number of comorbidities. Previous and recent MI were associated with higher mortality only in women. In this cohort analysis, female gender was not identified as an independent risk factor for outcome after CABG. [ABSTRACT FROM AUTHOR]

This article discusses three studies related to cardiovascular disease. The first study examines the use of genetic information to improve risk assessment for cardiovascular events. The second study explores the role of the spleen in cardioprotective effects. The third study investigates the mechanisms of sudden cardiac arrest in patients without obstructive coronary artery disease. These studies provide valuable insights into risk assessment, cardioprotective mechanisms, and the pathophysiology of sudden cardiac arrest. Further research is needed in these areas to improve patient care and outcomes. [Extracted from the article]

Multivessel coronary artery disease is present in ∼50% of patients with acute coronary syndrome and, compared with single-vessel disease, entails a higher risk of new ischaemic events and a worse prognosis. Randomized controlled trials have shown the superiority of 'complete revascularization' over culprit lesion-only treatment. Trials, however, only included patients treated with percutaneous coronary intervention (PCI), and evidence regarding complete revascularization with coronary artery bypass graft (CABG) surgery after culprit lesion-only PCI ('hybrid revascularization') is lacking. The CABG after PCI is an open, non-negligible therapeutic option, for patients with non-culprit left main and/or left anterior descending coronary artery disease where evidence in chronic coronary syndrome patients points in several cases to a preference of CABG over PCI. This valuable but poorly studied 'PCI first-CABG later' option presents, however, relevant challenges, mostly in the need of interrupting post-stenting dual antiplatelet therapy (DAPT) for surgery to prevent excess bleeding. Depending on patients' clinical characteristics and coronary anatomical features, either deferring surgery after a safe interruption of DAPT or bridging DAPT interruption with intravenous short-acting antithrombotic agents appears to be a suitable option. Off-pump minimally invasive surgical revascularization, associated with less operative bleeding than open-chest surgery, may be an adjunctive strategy when revascularization cannot be safely deferred and DAPT is not interrupted. Here, the rationale, patient selection, optimal timing, and adjunctive strategies are reviewed for an ideal approach to hybrid revascularization in post-acute coronary syndrome patients to support physicians' choices in a case-by-case patient-tailored approach.

Coronary heart disease is a prevalent cardiovascular ailment globally, with myocardial infarction (MI) being one of its most severe manifestations. The morbidity and mortality of MI are escalating, showing an increasing trend among younger, highly educated individuals, thereby posing a serious threat to public health. Currently, thrombolysis, percutaneous coronary intervention, and coronary artery bypass grafting are the primary clinical treatments for MI. Although these methods significantly reduce patient mortality, complications often result in poor prognoses. Due to limitations in chemical synthetic drug research, the focus has shifted towards developing herbs based on natural substances. Natural medicines represent a novel approach for safer and more effective MI management and treatment. They can control multiple pathogenic variables by targeting various pathways and systems. This paper investigates the molecular mechanisms of MI and evaluates the application of natural products and medicinal plants in MI treatment over the past 5 years, demonstrating their specific good therapeutic potential and superior tolerance. These natural therapies have been shown to mitigate myocardial cell damage caused by MI through mechanisms such as oxidative stress, inflammation, apoptosis, angiogenesis, myocardial fibrosis, autophagy, endoplasmic reticulum stress, mitophagy, and pyroptosis. This review offers the latest insights into the application of natural products andmedicinal plants inMI treatment, elucidating their mechanisms of action and serving as an important reference for MI prevention.

Background Hemodynamic stability is crucial during coronary artery bypass grafting (CABG) surgery to reduce perioperative complications. Dexmedetomidine, an alpha-2 adrenergic agonist, has been increasingly used for its sedative, analgesic, and sympatholytic properties. This study aims to evaluate the effects of intraoperative dexmedetomidine administration on hemodynamic parameters during CABG surgery. Materials and Methods A randomized controlled trial was conducted on 120 patients undergoing elective CABG surgery. Patients were randomly assigned into two groups: Group D (dexmedetomidine, n=60) and Group C (control, n=60). Group D received a loading dose of dexmedetomidine (0.5 μg/kg) followed by a maintenance infusion of 0.4 μg/kg/h until the end of surgery. Group C received an equivalent volume of saline as placebo. Hemodynamic parameters, including heart rate (HR), mean arterial pressure (MAP), and cardiac output (CO), were recorded at baseline, after induction, during cardiopulmonary bypass, and postoperatively. Statistical analysis was performed using ANOVA and t-tests. Results The administration of dexmedetomidine significantly reduced HR and MAP compared to the control group. At the end of surgery, Group D showed a 15% reduction in HR (p<0.001) and a 20% decrease in MAP (p<0.001) compared to baseline. Additionally, CO was better maintained in Group D, with an average CO of 5.5 L/min compared to 4.8 L/min in Group C (p=0.03). The incidence of intraoperative hypotension was lower in Group D (10%) compared to Group C (25%) (p=0.02). Postoperative recovery was also smoother in Group D, with a lower requirement for vasoactive drugs. Conclusion Intraoperative administration of dexmedetomidine during CABG surgery significantly improves hemodynamic stability, reducing the incidence of intraoperative hypotension and maintaining cardiac output. Dexmedetomidine may be a valuable adjunct in managing patients undergoing cardiac surgery. [ABSTRACT FROM AUTHOR]

Admission systolic blood pressure is a significant predictor of in-hospital mortality in patients with acute type A aortic dissection (ATAAD). While previous studies have focussed on recording the highest blood pressure value from both arms, this study aimed to evaluate the associations between blood pressure in bilateral arms and in-hospital mortality. Data were analysed from 262 patients with ATAAD treated at a single centre. The relationship between bilateral arm blood pressure upon admission and in-hospital mortality was assessed in a logistic regression model. To comprehensively evaluate potential non-linear relationships, the association between admission bilateral systolic blood pressure (SBP) and the risk of in-hospital mortality was analysed using restricted cubic splines on a continuous scale. Mean age was 53.6±12.5 years and 194 (74.0%) were male. Baseline and operative data showed that ages, body mass index, smoking, left-arm SBP, left-arm diastolic blood pressure (DBP), right-arm SBP, right-arm DBP, syncope, cerebral/cardiac ischaemia, retrograde brain perfusion, Bentall procedure, coronary artery bypass grafting, and aortic valve replacement significantly differed among the left-arm SBP tertiles. In-hospital mortality was 17.6% (46 of 262). Restricted cubic splines demonstrated that the relationship between presenting left-arm SBP and in-hospital mortality followed a U-shaped curve, whereas non-linearity was not detected in the right arm. This study found a U-shaped association between admission left-arm SBP and in-hospital mortality in ATAAD surgery patients, whereas a non-linearity relationship was not detected for right-arm SBP. Low left-arm SBP independently correlated with increased in-hospital mortality, underscoring the significance of bilateral blood pressure differences in ATAAD prognosis. [ABSTRACT FROM AUTHOR]

Diabetic patients with coronary artery disease may benefit from elective coronary artery bypass graft (CABG) surgery. It is unknown whether this merit is transferable to patients with acute myocardial infarction (AMI) undergoing surgery. A total of 1,427 patients underwent CABG within 48 hours of being diagnosed with AMI at the current institution between 2001 and 2019. Of these patients, 206 (14.4%) had insulin-dependent diabetes mellitus (IDDM) and 148 (10.4%) had non-insulin dependent diabetes mellitus (NIDDM). Retrospective data analysis was performed. Patients with NIDDM showed the highest perioperative risk profile, with a EuroScore II of 11.6 (±10.3) compared with 7.8 (±8.0) in non-diabetic patients and 8.4 (±7.8) in patients with IDDM (p<0.001). Sub-analysis demonstrated a higher proportion of non-ST-elevation myocardial infarction patients in the NIDDM cohort compared with the IDDM cohort (70.9% vs 56.8%; p=0.005). Postoperatively, NIDDM patients had more sepsis (p<0.01) and longer ventilation times (p<0.001) compared with non-DM and IDDM patients (p<0.01). Wound healing complications were rare, but almost twice as high in NIDDM patients compared with non-DM and IDDM patients (4.7% vs 0.9% vs 2.4%, respectively). The 30-day mortality was highest in the NIDDM cohort (18.3% vs 11.3% vs 7.8%; p=0.012). Analysis of survival for up to 15 years revealed a significantly reduced survival of diabetic patients compared with non-diabetic patients, with lowest survival rates in NIDDM patients (p<0.001). Non-insulin dependent diabetes mellitus patients undergoing CABG within 48 hours of being diagnosed with AMI are at increased risk of short-term and long-term complications. Therefore, this particular group should undergo a careful evaluation concerning the expected risks and benefits of CABG in this setting. [ABSTRACT FROM AUTHOR]

Background To evaluate the midterm follow-up and 5-year survival outcome of the minimally invasive direct coronary artery bypass (MIDCAB) procedure compared with the survival of the general Swiss population. Methods Retrospective study on preoperative data, intraoperative data, and postoperative outcome of patients who underwent MIDCAB surgery between June 2010 and February 2019. To assess validity of this surgical therapy, outcomes were compared with survival data of a gender- and age-matched cohort of the general Swiss population taken from the database of the Swiss Federal Statistical Office. Results A total of 88 patients were included. Median (interquartile range [IQR[) age was 66 (56–75) years, and 27% (n = 24) were female. The median (IQR) length of the in-hospital stay was 7 (6–8) days. No postoperative stroke occurred. The 30-day mortality was 1.1% (n = 1). Reintervention for failed left internal mammary artery was needed in 1.1% (n = 1). The median (IQR) ejection fraction was 58% (47–60) preoperatively and remained stable during follow-up. The median (IQR) follow-up period was 3 (1.1–5.2) years. Five years postoperatively, 83% (confidence interval, 69–91) of the patients were alive, showing an overlap with the range of survival of the matched subcohort of the general Swiss population (range, 84–100%). Conclusion Though suffering from coronary heart disease, patients after MIDCAB show almost equal survival rates as an equivalent subcohort corresponding to the general Swiss population matched on age and gender. Thus, our data show this treatment to be safe and beneficial. [ABSTRACT FROM AUTHOR]

Background A significant impact of surgeons' experience on outcomes of off-pump coronary artery bypass (OPCAB) has been recognized through previous large-scale studies. However, a safe, effective, and concrete OPCAB training was yet to be identified. We evaluate a safety of our OPCAB training model with single left internal mammary artery (LIMA)–left anterior descending artery (LAD) as a reasonable first step. Methods Between January 2010 and June 2019, 180 patients with an isolated single coronary bypass of the LAD using LIMA as an in situ graft via median sternotomy fulfilled the inclusion criteria. Coronary arterial bypass under cardiopulmonary bypass (CPB), utilizing other graft material, minimal invasive direct coronary arterial bypass through left-sided thoracotomy, and multiple diseased coronary artery disease were excluded. The primary outcome is an early postoperative outcome (major adverse cardiac and cerebrovascular events [MACCEs]: myocardial infarction, coronary re-revascularization, stroke, acute renal failure, and all causes of death) between residents in training under supervision (group 1: n = 63) and experienced surgeons (group 2: n = 117). Trainees were already experienced in on-pump coronary artery bypass grafting. Results Preoperative variables were comparable. There was no significant difference in the rate of MACCEs between the two groups including hospital mortality (p = 1.000), perioperative myocardial infarction (p = 0.246), stroke (p = 0.655), and acute renal failure (p = 0.175). Conclusion The early postoperative outcome of off-pump LIMA to the LAD performed by trainees was comparable to those by experienced surgeons. Single LIMA-LAD was safely performed by trainees under supervision without CPB. In order to master OPCAB technique, single LAD bypass might be a reasonable first step to get into touch with the technical characteristics of this special procedure. [ABSTRACT FROM AUTHOR]

Background Although coronary artery bypass grafting (CABG) is performed via three different techniques, conventional, on-pump beating heart CABG (ONBHCAB), or off-pump CABG (OPCAB), data are limited to compare ONBHCAB with OPCAB. Methods We retrospectively investigated the postoperative cardiac biomarkers, creatine kinase-MB (CK-MB), and troponin I (cTnI), and early and late outcomes in 806 patients undergoing isolated ONBHCAB or OPCAB between February 2008 and September 2022. To eliminate the bias between different groups, propensity score matching was conducted to validate the findings. Results After matching, the number of each study group totaled 270 patients. In both complete and matched cohorts, early outcomes, including morbidities and mortalities, were similar. However, cTnI and CK-MB levels were significantly higher after ONBHCAB than after OPCAB with median peak cTnI of 9.85 versus 4.60 ng/mL and median peak CK-MB of 48.45 versus 17.10 ng/mL in the matched cohort, which were quite low, below the threshold for values defining perioperative myocardial infarction. At follow-up of 73 ± 45 months, the overall actuarial survival rates were similar between the ONBHCAB and OPCAB patients (86 vs. 87% at 5 years and 64 vs. 68% at 10 years, respectively, in the matched cohort). Conclusion ONBHCAB may be a comparable alternative to OPCAB with similar early and late outcomes, despite higher elevation of postoperative cardiac biomarkers. ONBHCAB provides more efficient hemodynamic support, providing a better surgical visual field, than OPCAB while reducing the risk of incomplete revascularization. [ABSTRACT FROM AUTHOR]

Background This study was conducted to evaluate whether myocardial viability assessed with cardiac magnetic resonance (CMR) affected long-term clinical outcomes after coronary artery bypass grafting (CABG) in patients with ischemic cardiomyopathy (ICMP). Methods Preoperative CMR with late gadolinium enhancement (LGE) was performed in 103 patients (64.9 ± 10.1 years, male:female = 82:21) with 3-vessel disease and left ventricular dysfunction (ejection fraction ≤ 0.35). Transmural extent of LGE was evaluated on a 16-segment model, and transmurality was graded on a 5-point scale: grades—0, absence; 1, 1 to 25%; 2, 26 to 50%; 3, 51 to 75%; 4, 76 to 100%. Median follow-up duration was 65.5 months (interquartile range = 27.5–95.3 months). Primary endpoint was the composite of all-cause mortality or hospitalization for congestive heart failure. Results Operative mortality was 1.9%. During the follow-up, all-cause mortality and readmission for congestive heart failure occurred in 29 and 8 patients, respectively. The cumulative incidence of the primary endpoint was 31.3 and 46.8% at 5 and 10 years, respectively. Multivariable analysis demonstrated that the number of segments with LGE grade 4 was a significant risk factor (hazard ratio 1.42, 95% confidence interval 1.10–1.83, p = 0.007) for the primary endpoint among the variables assessed by CMR. Other risk factors included age, dialysis, chronic obstructive pulmonary disease, and EuroSCORE II. Conclusion The number of myocardial segments with transmurality of LGE >75% might be a prognostic factor associated with the composite of all-cause mortality or hospitalization for congestive heart failure after CABG in patients with 3-vessel disease and ICMP.

Background The best surgical treatment strategy for coexisting coronary artery disease (CAD) and lung cancer (LC) remains controversial. This study analyzed the safety and efficacy of a simultaneous minimally invasive procedure for patients with CAD and LC. Methods Patients who underwent simultaneous minimally invasive off-pump coronary artery bypass grafting and lung resection from January 2016 to December 2021 were retrospectively analyzed. The procedure was performed in the fourth intercostal space through a small left anterolateral minithoracotomy. Harvesting of the left internal mammary artery (LIMA) and sewing of the anastomoses were performed under direct vision. Lung resections were performed with or without the assistance of a thoracoscope. Results Sixteen patients were included with a mean age of 67.13 ± 10.61 years. Procedural success occurred in all patients with a mean operative time of 366.88 ± 94.48 minutes. All patients received at least one coronary artery bypass LIMA graft. Pneumonectomy, lobectomy, segment resection, and wedge resection were performed in one (6.25%), eight (50%), two (12.5%), and five (31.25%) patients, respectively. There were no perioperative deaths or new myocardial infarctions. Complications included one case of postoperative bleeding, two lung infections, two cases of atelectasis, one case of pleural effusion, and one case of cardiac arrhythmia. All the patients were followed up for 1 to 57 months, cancer recurrence occurred in two patients, and one patient died. The remaining patients showed no evidence of tumor recurrence or myocardial infarction. Conclusion This simultaneous minimally invasive procedure is safe and effective for selected patients with CAD and LC. [ABSTRACT FROM AUTHOR]

Background Guidelines on myocardial revascularization define recommendations for percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery. Only little information exists on long-term follow-up and quality of life (QoL) after CABG preceded by PCI. The aim of our study was to evaluate the impact of prior PCI on outcome and QoL in patients with stable coronary artery disease who underwent CABG. Methods In our retrospective study, CABG patients were divided in: CABG preceded by PCI: PCI-first (PCF), and CABG-only (CO) groups. The PCF group was further divided in guideline-conform (GCO) and guideline nonconform (GNC) subgroups, according to the SYNTAX score (2014 European Society of Cardiology [ESC]/European Association for Cardio-Thoracic Surgery [EACTS] guidelines). Thirty days mortality, major adverse cardiac events, and QoL using the European Quality-of-Life–5 Dimensions were evaluated. Results A total of 997 patients were analyzed, of which 784 underwent CABG without (CO), and 213 individuals with prior PCI (PCF). The latter group consisted of 67 patients being treated in accordance (GCO), and 24 in discordance (GNC) to the 2014 ESC/EACTS guidelines. Reinfarction (PCF: 3.8% vs. CO: 1.0%; p = 0.024), re-angiography (PCF: 17.6% vs. CO: 9.0%; p = 0.004), and re-PCI (PCF: 10.4% vs. CO: 3.0%; p < 0.001) were observed more frequently in PCF patients. Also, patients reported better health status in the CO compared to PCF group (CO: 72.48 ± 19.31 vs. PCF: 68.20 ± 17.86; p = 0.01). Patients from the guideline nonconform subgroup reported poorer health status compared to the guideline-conform group (GNC: 64.23 ± 14.56 vs. GCO: 73.42 ± 17.66; p = 0.041) and were more likely to require re-PCI (GNC: 18.8% vs. GCO: 2.4%; p = 0.03). Also, GNC patients were more likely to have left main stenosis (GCO: 19.7% vs. GNC: 37.5%; p < 0.001) and showed higher preinterventional SYNTAX score (GCO: 18.63 ± 9.81 vs. GNC: 26.67 ± 5.07; p < 0.001). Conclusion PCI preceding CABG is associated with poorer outcomes such as reinfarction, re-angiography, and re-PCI, but also worse health status and higher rehospitalization. Nevertheless, results were better when PCI was guideline-conformant. This data should impact the Heart Team decision. [ABSTRACT FROM AUTHOR]

Atrial fibrillation (AF) and pericardial effusion are notable complications following coronary artery bypass grafting (CABG), contributing to increased morbidity and healthcare costs. Posterior pericardiotomy has been proposed to mitigate these complications. This systematic review and meta-analysis aim to evaluate the efficacy of posterior pericardiotomy in reducing postoperative AF and pericardial effusion in isolated CABG patients. A comprehensive literature search, adhering to PRISMA guidelines, was conducted across PubMed, MEDLINE via Ovid, Embase, Scopus, the Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov up to December 2023. Only randomised controlled trials (RCTs) comparing prophylactic posterior pericardiotomy to control treatments in adult CABG patients were included. The primary outcomes assessed were the incidences of postoperative AF and pericardial effusion. The meta-analysis incorporated 16 RCTs with a total of 2414 patients. The findings demonstrated a significant reduction in the incidence of postoperative AF (Odds Ratio = 0.34, 95 % CI: 0.25–0.48, P < 0.00001) and pericardial effusion (Odd Ratio = 0.24, 95 % CI: 0.15–0.38, P < 0.0001) in the group undergoing posterior pericardiotomy. However, the analysis revealed substantial heterogeneity and publication bias in the included studies. The posterior pericardiotomy is effective in reducing the incidences of AF and pericardial effusion in patients undergoing isolated CABG. Despite the positive outcomes, the presence of heterogeneity and publication bias warrants a cautious interpretation of the results and underscores the need for further multicentre RCTs in this area. • AF is the most common arrhythmia following CABG with an incidence of 30 %. • Posterior pericardiotomy significantly reduces the pericardial effusion and AF. • Limitations in current trials highlight the need for further research.

CORONARY artery bypass , *POSITRON emission tomography , *CORONARY artery calcification , *COMPUTED tomography , *CORONARY artery disease - Abstract
Purpose: The value of preoperative multidisciplinary approach remains inadequately delineated in forecasting postoperative outcomes of patients undergoing coronary artery bypass grafting (CABG). Herein, we aimed to ascertain the efficacy of multi-modality cardiac imaging in predicting post-CABG cardiovascular outcomes. Methods: Patients with triple coronary artery disease underwent cardiac sodium [18F]fluoride ([18F]NaF) positron emission tomography/computed tomography (PET/CT), coronary angiography, and CT-based coronary artery calcium scoring before CABG. The maximum coronary [18F]NaF activity (target-to-blood ratio [TBR]max) and the global coronary [18F]NaF activity (TBRglobal) was determined. The primary endpoint was perioperative myocardial infarction (PMI) within 7-day post-CABG. Secondary endpoint included major adverse cardiac and cerebrovascular events (MACCEs) and recurrent angina. Results: This prospective observational study examined 101 patients for a median of 40 months (interquartile range: 19–47 months). Both TBRmax (odds ratio [OR] = 1.445; p = 0.011) and TBRglobal (OR = 1.797; P = 0.018) were significant predictors of PMI. TBRmax>3.0 (area under the curve [AUC], 0.65; sensitivity, 75.0%; specificity, 56.8%; p = 0.036) increased PMI risk by 3.661-fold, independent of external confounders. Kaplan–Meier test revealed a decrease in MACCE survival rate concomitant with an escalating TBRmax. TBRmax>3.6 (AUC, 0.70; sensitivity, 76.9%; specificity, 73.9%; p = 0.017) increased MACCEs risk by 5.520-fold. Both TBRmax (hazard ratio [HR], 1.298; p = 0.004) and TBRglobal (HR = 1.335; p = 0.011) were significantly correlated with recurrent angina. No significant associations were found between CAC and SYNTAX scores and between PMI occurrence and long-term MACCEs. Conclusion: Quantification of coronary microcalcification activity via [18F]NaF PET displayed a strong ability to predict early and long-term post-CABG cardiovascular outcomes, thereby outperforming conventional metrics of coronary macrocalcification burden and stenosis severity. Trial registration: : The trial was registered with the Chinese Clinical Trial Committee (number: ChiCTR1900022527; URL: www.chictr.org.cn/showproj.html?proj=37933). [ABSTRACT FROM AUTHOR]

This study investigates the characteristics of cardiac mesenchymal stem cell-like cells (CMSCLCs) isolated from the right atrial appendage of human donors with ischemia and a young patient with endocarditis (NE-CMSCLCs). Typical CMSCLCs from ischemic heart patients were derived from coronary artery bypass grafting procedures and compared against bone marrow mesenchymal stromal cells (BM-MSCs). NE-CMSCLCs had a normal immunophenotype, but exhibited enhanced osteogenic differentiation potential, rapid proliferation, reduced senescence, reduced glycolysis, and lower reactive oxygen species generation after oxidative stress compared with typical ischemic CMSCLCs. These differences suggest a unique functional status of NE-CMSCLCs, influenced by the donor health condition. Despite large variances in their paracrine secretome, NE-CMSCLCs retained therapeutic potential, as indicated by their ability to protect hypoxia/reoxygenation-injured human cardiomyocytes, albeit less effectively than typical CMSCLCs. This research describes a unique cell phenotype and underscores the importance of donor health status in the therapeutic efficacy of autologous cardiac cell therapy. [ABSTRACT FROM AUTHOR]

Myocardial infarction (MI) is a significant cause of death in diabetic patients. Growing evidence suggests that mitochondrial dysfunction contributes to heart failure in diabetes. However, the molecular mechanisms of mitochondrial dysfunction mediating heart failure in diabetes are still poorly understood. We examined MRPL12 levels in right atrial appendage tissues from diabetic patients undergoing coronary artery bypass graft (CABG) surgery. Using AC-16 cells overexpressing MRPL12 under normal and hyperglycemic conditions we performed mitochondrial functional assays OXPHOS, bioenergetics, mitochondrial membrane potential, ATP production and cell death. We observed elevated MRPL12 levels in heart tissue samples from diabetic patients with ischemic heart disease compared to non-diabetic patients. Overexpression of MRPL12 under hyperglycemic conditions did not affect oxidative phosphorylation (OXPHOS) levels, cellular ATP levels, or cardiomyocyte cell death. However, notable impairment in mitochondrial membrane potential (MMP) was observed under hyperglycemic conditions, along with alterations in both basal respiration oxygen consumption rate (OCR) and maximal respiratory capacity OCR. Overall, our results suggest that MRPL12 may have a compensatory role in the diabetic myocardium with ischemic heart disease, suggesting that MRPL12 may implicate in the pathophysiology of MI in diabetes. [Display omitted] • MRPL12 levels were increased in the Right atrial appendages (RAA) tissues of human diabetic patients undergoing CABG. • MRPL12 overexpression in AC-16 cardiomyocytes under hyperglycemic conditions affects mitochondrial membrane potential and bioenergetics, however oxidative phosphorylation was not significantly altered nor were ATP production or cell death. • Increased expression of MRPL12 may act as a compensatory mechanism in diabetic cardiomyocytes.

- Abstract
• Normal saline has been considered to have deleterious effects on kidney function. • We compared balanced solution versus saline in off-pump coronary bypass surgery. • The study did not demonstrate a significant difference in acute kidney injury. To determine whether balanced solutions can reduce the incidence of acute kidney injury after off-pump coronary artery bypass surgery compared with saline. Randomized controlled trial. Single tertiary care center. Patients who underwent off-pump coronary artery bypass surgery between June 2014 and July 2020. Balanced solution-based chloride-restrictive intravenous fluid strategy. The primary outcome was acute kidney injury within 7 postoperative days, as defined by the 2012 Kidney Disease: Improving Global Outcomes Clinical Practice Guideline. The incidence of acute kidney injury was 4.4% (8/180) in the balanced group and 7.3% (13/178) in the saline group. The difference was not statistically significant (risk difference, −2.86%; 95% confidence interval [CI], −7.72% to 2.01%; risk ratio, 0.61, 95% CI, 0.26 to 1.43; p = 0.35). Compared with the balanced group, the saline group had higher levels of intraoperative serum chloride and lower base excess, which resulted in a lower pH. In patients undergoing off-pump bypass surgery with a normal estimated glomerular filtration rate, the intraoperative balanced solution-based chloride-restrictive intravenous fluid administration strategy did not decrease the rate of postoperative acute kidney injury compared with the saline-based chloride-liberal intravenous fluid administration strategy.

- Abstract
Wide variations exist in the use of pulmonary artery catheters (PACs) and echocardiography in the field of cardiac surgery. A national survey promoted by the Italian Association of Cardio-Thoracic Anesthesiologists and Intensive Care was conducted. The study occurred in Italian cardiac surgery centers (n = 71). Anesthesiologists-intensivists were enrolled. Anonymous questionnaires were used to investigate the use of PACs and echocardiography in the operating room (OR) and intensive care unit (ICU). A total of 257 respondents (32.2% response rate) from 59 centers (83.1% response rate) participated. Use of PACs seems less common in ORs (median insertion in 20% [5-70] of patients), with slightly higher use in ICUs; in about half of cases, it was the continuous cardiac output monitoring system of choice. Almost two-thirds of respondents recently inserted at least one PAC within a few hours of ICU admission, despite its need being largely preoperatively predictable. Protocols regulating PAC insertion were reported by 25.3% and 28% of respondents (OR and ICU, respectively). Transesophageal echocardiography (TEE) was performed intraoperatively in >75% of patients by 86.4% of respondents; only 23.7% stated that intraoperative TEE relied on anesthesiologists. Tissue Doppler and/or 3D imaging were widely available (87.4% and 82%, respectively), but only 37.8% and 24.3% of respondents self-declared skills in these modalities, respectively; 77.1% of respondents had no echocardiography certification, nor were pursuing certification (various reasons); 40.9% had not attended recent echocardiography courses. Lower PAC use was associated with university hospitals (OR: p = 0.014, ICU: p = 0.032) and with lower interventions/year (OR: p = 0.023). Higher independence in performing TEE was reported in university hospitals (OR: p < 0.001; ICU: p = 0.006), centers with higher interventions/year (OR: p = 0.019), and by respondents with less experience in cardiology (ICU: p = 0.046). Variability in the use of PACs and echocardiography was found. Protocols regulating the use of PACs seem infrequent. University centers use PACs less and have greater skills in TEE. Training and certifications in echocardiography should be encouraged. [ABSTRACT FROM AUTHOR]

Background We compared total arterial revascularization (TAR) versus conventional revascularization (CR) in terms of left ventricular function recovery in patients with multivessel coronary artery disease (CAD) and reduced left ventricular ejection fraction (LVEF). Methods We conducted a retrospective cohort study of 162 consecutive patients with multivessel CAD and reduced LVEF who underwent isolated coronary artery bypass grafting at our institution between January 2013 and July 2022. We assessed left ventricular function by transthoracic echocardiography at admission, before discharge, and at follow-up of 3, 6, and 12 months, using LVEF, global longitudinal peak strain, end-diastolic volume index, and end-systolic volume index. We also evaluated mitral valve regurgitation and graft patency rate at 1 year. Results The TAR group had a significantly higher increase in LVEF and global longitudinal peak strain, and a significantly lower decrease in end-diastolic volume index and end-systolic volume index than the CR group at 6 and 12 months after surgery. The TAR group also had a significantly lower degree of mitral valve regurgitation than the CR group at all-time points within 12 months after surgery. The TAR group had a significantly higher graft patency rate than the CR group at 12 months. There was no significant difference in hospital mortality or repeat revascularization between the groups. Conclusions TAR was associated with better recovery of left ventricular function than CR in patients with multivessel CAD and reduced LVEF. Further studies are needed to confirm these findings in this high-risk population. What is already known on this topic: Previous studies have shown that coronary artery bypass grafting (CABG) can improve left ventricular function in patients with ischemic cardiomyopathy and heart failure. Total arterial revascularization (TAR) has been shown to have superior long-term outcomes than conventional revascularization (CR). Limited data exist comparing TAR versus CR for left ventricular recovery in those with multivessel disease and reduced ejection fraction. What this study adds: This study compared the recovery of left ventricular function after TAR versus CR in patients with multivessel coronary artery disease and reduced ejection fraction. The results showed that TAR was associated with better recovery of left ventricular function than CR. TAR was also associated with lower degree of mitral regurgitation and higher graft patency rate than CR at 12 months after surgery. How this study might affect research, practice or policy: This study suggests that TAR may have a beneficial effect on the remodeling and contractility of the left ventricle in this patient population. TAR may be the optimal revascularization strategy for patients with multivessel CAD and reduced LVEF, as it may improve left ventricular function and overall outcomes. More studies are needed to address these issues and to provide more robust evidence for the use of TAR in this high-risk population. [ABSTRACT FROM AUTHOR]

Background: Percutaneous coronary intervention (PCI), also known as coronary angioplasty, is the preferred strategy for treating obstructive coronary artery disease. Existing literature suggests the worsening of clinical outcomes in patients with previous coronary artery bypass grafting (CABG) history. In light of this, a comprehensive systematic review and meta-analysis was performed. Methods: Databases including PubMed, Cochrane Library, and ScienceDirect were utilized for the inclusive systematic search dating from inception to September 01, 2023. The risk of bias assessment was performed using the Newcastle-Ottawa scale for cohort studies, and the Cochrane Risk of Bias Tool for randomized controlled trials. Results: Ultimately, there were 16 eligible studies pooled together, involving a total of 250 684 patients, including 231 552 CABG-naïve patients, and 19 132 patients with a prior history of CABG. Overall, patients with CABG history were associated with significantly greater short-term mortality (P =.004), long-term mortality (P =.005), myocardial infarction (P <.00001), major adverse cardiovascular events (P =.0001), and procedural perforation (P <.00001). Contrastingly, CABG-naïve patients were associated with significantly greater risk of cardiac tamponade (P =.02) and repeat CABG (P =.03). No significant differences in stroke, bleeding, revascularization, or repeat PCI were observed. Conclusion: Comparatively worsened clinical outcomes were observed, as patients with prior CABG history typically exhibit complex coronary anatomy, and have higher rates of comorbidities in comparison to their CABG-naïve counterparts. The refinement of current procedural and surgical techniques, in conjunction with continued research endeavors, are needed in order to effectively address this trend. [ABSTRACT FROM AUTHOR]

Background: The objective of this study is to investigate whether the use of antegrade perfusion with terminal non-cardioplegic warm blood (TNWB) before aortic unclamping in single-clamp technique coronary artery bypass has a positive impact on intraoperative heartbeat recovery. Methods: Between December 2022 and May 2023, 40 consecutive patients undergoing coronary artery bypass using single-clamp technique were randomized into one of two groups: the TNWB group received an antegrade perfusion with TNWB before removing the aortic cross-clamp (n = 20), while the control group did not receive (n = 20). The time intervals between coronary perfusion and the onset of the first heartbeats and sinus rhythms, occurrences of spontaneous sinus rhythm, intraoperative defibrillation requirements, as well as postoperative CK-MB and troponin T levels were recorded and subjected to analysis. Results: In the TNWB group, the median onset of the first heartbeats after the initiation of coronary perfusion was 34 s (4-100), while in the control group, it was 90 s (15–340) (p < 0.001). The median onset of the sinus rhythms was 100 s (28–290) in the TNWB group and was 132 s (45–350) in the control group (p = 0.023). The occurrence of intraoperative arrhythmias was 15% in the TNWB group compared to 50% in the control group (p = 0.018), and the incidence for internal defibrillation was 5% in the TNWB group and was 30% in the control group (p = 0.037). The TNWB group showed the median CK-MB levels at 6 h postoperative was 14.10 ng/mL (9.78–19.26), compared to 18.31 ng/mL (13.98–23.80) in the control group (p = 0.045). Conclusions: During single clamp coronary artery bypass, administration TNWB into the aortic root before aortic unclamping has the potential to enhance heartbeat recovery, as evidenced by the shortened time to the initial heartbeat and the establishment of sinus beats following coronary perfusion.

Background: Coronary artery bypass grafting remains the standard of care for advanced and multifocal coronary artery disease; however, for patients that are surgical candidates, total arterial revascularization (TAR) remains underutilized due to concerns such as sternal wound infections and the learning curve. We present the results of a large cohort of mid-career surgeons transitioning to TAR, focusing on short-term outcomes and the learning curve. Methods: The surgeons transitioned to using TAR as the preferred revascularization technique in August of 2017. The Society of Thoracic Surgeons database was reviewed to identify all patients who underwent isolated non-emergent CABG performed by a single surgeon from January 2014 through January 2022. Patients were divided into two groups—those who had TAR and those who had traditional CABG using one internal mammary artery and vein grafts (IMA-SVG). Results: Eight hundred ninety-eight patients meet inclusion criteria (458 IMA-SVG and 440 TAR). The TAR group had slightly longer cardiopulmonary bypass time, cross clamp times, and operative times (all p < 0.05); however, ICU stay was shorter and 30-day readmission rate was lower for TAR compared to IMA-SVG (all p < 0.05). The TAR group also required fewer postoperative transfusions (p = 0.005). There was no difference in prolonged intubation, stroke, length of stay, mortality, or sternal wound complications between groups (all p > 0.05). The average TAR was 30 min longer; however, learning curves, stratified by number of grafts placed, showed no significant learning curve associated with TAR. Conclusions: An experienced surgeon transitioning from IMA-SVG to TAR slightly increases operative time, but decreases ICU stay, readmissions, and postoperative transfusions with no significant difference in rates of immediate post-operative complications or 30-day mortality, with a minimal learning curve.

Coronary artery bypass grafting (CABG) utilizing saphenous vein grafts (SVGs) stands as a fundamental approach to surgically treating coronary artery disease. However, the long-term success of CABG is often compromised by the development of intimal hyperplasia (IH) and subsequent graft failure. Understanding the mechanisms underlying this pathophysiology is crucial for improving graft patency and patient outcomes. Objectives: This study aims to explore the potential of an ex vivo model utilizing SVG to investigate IH and re-endothelialization. Methods: A thorough histological examination of 15 surplus SVG procured from CABG procedures at Hospital Canselor Tuanku Muhriz, Malaysia, was conducted to establish their baseline characteristics. Results: SVGs exhibited a mean diameter of 2.65 ± 0.93 mm with pre-existing IH averaging 0.42 ± 0.13 mm in thickness, alongside an observable lack of luminal endothelial cell lining. Analysis of extracellular matrix components, including collagen, elastin, and glycosaminoglycans, at baseline and after 7 days of ex vivo culture revealed no significant changes in collagen but demonstrated increased percentages of elastin and glycosaminoglycans. Despite unsuccessful attempts at re-endothelialization with blood outgrowth endothelial cells, the established ex vivo SVG IH model underscores the multifaceted nature of graft functionality and patency, characterized by IH presence, endothelial impairment, and extracellular matrix alterations post-CABG. Conclusions: The optimized ex vivo IH model provides a valuable platform for delving into the underlying mechanisms of IH formation and re-endothelialization of SVG. Further refinements are warranted, yet this model holds promise for future research aimed at enhancing graft durability and outcomes for CAD patients undergoing CABG. [ABSTRACT FROM AUTHOR]

Background/Objectives: Grafting of LIMA to LAD has long been considered the gold-standard conduit choice for patients undergoing CABG. Despite this, the LSV remains the most used conduit by volume and some patients may not receive even a single arterial conduit. However, the outcomes in this group are not frequently explored. This study, therefore, compares in-hospital outcomes of patients who underwent CABG without any arterial conduits to those who received at least one arterial conduit. Methods: Retrospective propensity-matched database analysis of consecutive patients undergoing CABG in the UK between 1996 and 2019 using data from the National Adult Cardiac Surgery Audit. Results: 335,144 patients underwent CABG, with 6% receiving venous conduits only; matched outcomes are reported for 39,812 patients. In both unmatched and matched groups, we found a significant increase in mortality with the use of veins only (matched mortality 5.3% vs. 3.8%, p < 0.001) with estimated treatment effect for mortality OR 1.43, p < 0.001 (95% CI: 1.31–1.57). We also identified greater rates of post-operative dialysis, IABP insertion, and length of hospital stay in this group. Conclusions: We identified a significant increase in in-hospital mortality with the use of veins only compared to using at least one arterial graft to the LAD. While a single arterial graft should be prioritised wherever possible, venous revascularisation retains a critical role for specific patients. We must, therefore, continue to conduct research addressing the mechanisms underlying and propagating vein graft disease in order better to optimise outcomes for this niche patient group after CABG.

Background/Objectives: The demographic shift towards an aging population necessitates a reevaluation of surgical interventions like coronary artery bypass grafting (CABG) in octogenarians. This study aims to elucidate the outcomes of CABG in octogenarians with heart failure and reduced ejection fraction (HFrEF), a group traditionally considered at high risk for such procedures. Methods: Conducted across four academic hospitals in Germany from 2017 to 2023, this retrospective multicenter study assessed 100 patients (50 octogenarians ≥80 years and 50 non-octogenarians <80 years) with HFrEF undergoing isolated CABG. Through propensity score matching, the study aimed to compare the incidence of major adverse cardiac and cerebrovascular events (MACCEs), as well as other clinical endpoints, between the two groups. Statistical analyses included chi-square, ANOVA, Mann–Whitney U test, Cox regression, and logistic regression, aiming to identify significant differences in outcomes. Results: The study revealed no significant difference in the combined incidence of MACCEs between octogenarians and non-octogenarians (OR: 0.790, 95% CI: 0.174–3.576, p = 0.759). Mortality rates were similar across groups (7% each, p = 1.000), as were occurrences of postoperative myocardial infarction (2% each, p = 1.000) and stroke (3% total). Secondary outcomes like delirium (17% total, no significant age group difference, p = 0.755), acute kidney injury (18% total, p = 0.664), and the need for dialysis (14% total, p = 1.000) also showed no differences between age groups. Interestingly, non-octogenarians required more packed red blood cells during their stay (p = 0.008), while other postoperative care metrics, such as hospital and ICU length of stay and ventilation hours, were comparable across groups. Conclusion: This multicenter study highlights that CABG is a viable and safe surgical option for octogenarians with HFrEF, challenging prior assumptions about the elevated risks associated with performing this procedure in older patients. The absence of significant differences in the incidence of MACCEs and other postoperative complications across age groups emphasizes the importance of careful patient selection and perioperative management. These findings advocate for a more inclusive approach to surgical treatment for octogenarians with HFrEF, suggesting that age alone should not be a determinant for CABG eligibility. This study contributes critical insights into optimizing care for a high-risk demographic, indicating a need for tailored guidelines that accommodate the aging population with complex cardiac conditions.

Background: The development of acute kidney injury (AKI) post-cardiac surgery significantly increases patient morbidity and healthcare costs. Prior researches have established Syndecan-1 (SDC-1) as a potential biomarker for endothelial injury and subsequent acute kidney injury development. This study assessed whether postoperative SDC-1 levels could further predict AKI requiring kidney replacement therapy (AKI-KRT) and AKI progression. Methods: In this prospective study, 122 adult cardiac surgery patients, who underwent valve or coronary artery bypass grafting (CABG) or a combination thereof and developed AKI within 48 h post-operation from May to September 2021, were monitored for the progression to stage 2–3 AKI or the need for KRT. We analyzed the predictive value of postoperative serum SDC-1 levels in relation to multiple endpoints. Results: In the study population, 110 patients (90.2%) underwent cardiopulmonary bypass, of which thirty received CABG or combined surgery. Fifteen patients (12.3%) required KRT, and thirty-eight (31.1%) developed progressive AKI, underscoring the severe AKI incidence. Multivariate logistic regression indicated that elevated SDC-1 levels were independent risk factors for progressive AKI (OR = 1.006) and AKI-KRT (OR = 1.011). The AUROC for SDC-1 levels in predicting AKI-KRT and AKI progression was 0.892 and 0.73, respectively, outperforming the inflammatory cytokines. Linear regression revealed a positive correlation between SDC-1 levels and both hospital (β = 0.014, p = 0.022) and ICU stays (β = 0.013, p < 0.001). Conclusion: Elevated postoperative SDC-1 levels significantly predict AKI progression and AKI-KRT in patients following cardiac surgery. The study's findings support incorporating SDC-1 level monitoring into post-surgical care to improve early detection and intervention for severe AKI. [ABSTRACT FROM AUTHOR]

Aim Background Design Methods Results Conclusion Reporting Method Patient or Public Contribution To examine the influence of clinical and demographic factors on self‐care behaviour and hospitalization rates among patients with coronary heart disease awaiting coronary artery bypass grafting.Appropriate self‐care behaviour can improve the management of patients with coronary heart disease and reduce hospitalization rates among those awaiting coronary artery bypass graft surgery. However, little is known about the influence of clinical and demographic factors on self‐care or hospitalizations in this population.A cross‐sectional study.A convenience sample of 99 participants diagnosed with coronary heart disease awaiting coronary artery bypass grafting surgery were recruited from an outpatient clinic of a public tertiary hospital in southern Thailand. Data were collected on clinical (left ventricular ejection fraction, symptom severity and comorbid disease) and demographic (age, education level and marital status) factors, self‐care behaviour and hospitalization rates. Path analysis using LISREL was performed to examine the influence of self‐care on hospitalizations, with clinical and demographic factors as moderators.Path analysis showed that clinical and demographic factors accounted for nearly half of the variance (46%) in self‐care, and that self‐care accounted for nearly half of the variance (48%) in hospitalization rates.Our findings demonstrate that clinical and demographic factors play an important role in self‐care behaviour, and in turn hospitalization rates of pre‐coronary artery bypass graft surgery patients. It is suggested that the period pre‐surgery is an ideal time to introduce programmes designed to bolster self‐care and minimize uncertainty among this patient population and that nurses are well‐positioned to do so.Study methods and results reported in adherence to the STROBE checklist.Patients contributed their consent, time and data to the study.

Background: Severe pain occurs after cardiac surgery in the sternum and chest tubes sites. Although analgesia targeting the sternum is often prioritized, the analgesia of the drain site is sometimes overlooked. This study of patients undergoing coronary artery bypass grafting (CABG) aimed to provide optimized analgesia for both the sternum and the chest tubes area by combining parasternal block (PSB) and serratus anterior plane block (SAPB). Methods: Ethics committee approval (E.Kurul-E2-24-6176, 07/02/2024) was received for the study. Then, the trial was registered on www.clinicaltrials.gov (https://clinicaltrials.gov/) under the identifier NCT05427955 on 17/03/2024. Twenty patients between the ages of 18–80, with ASA physical status classification II-III, undergoing coronary artery bypass grafting CABG with sternotomy, were included. While the patients were under general anesthesia, PSB was performed through the second and fourth intercostal spaces, and SAPB was performed over the sixth rib. The primary outcome was VAS (Visual Analog Scale) during the first 12 h after extubation. The secondary outcomes were intraoperative remifentanil consumption and block-related side effects. Results: The average age of the patients was 64 years. Five patients were female, and 15 were male. For the sternum area, only one patient had resting VAS scores of 4, while the VAS scores for resting for the other patients were below 4. For chest tubes area, only two patients had resting VAS scores of 4 or above, while the resting VAS scores for the other patients were below 4. The patients' intraoperative remifentanil consumption averaged 2.05 mg. No side effects related to analgesic protocol were observed in any of the patients. Conclusions: In this preliminary study where PSB and SAPB were combined in patients undergoing CABG, effective analgesia was achieved for the sternum and chest tubes area. [ABSTRACT FROM AUTHOR]

The heart and the thyroid gland are two of the most vital organs of the human body. The optimum functioning of these two organs is essential for the well-being of the body. These two organs share a twin-way relationship. Mild deviation from the normal range of thyroid hormone levels affects the heart. Hence, thyroid disorders (TD) are suspected to be strongly associated with cardiovascular diseases (CVD), especially in cases undergoing coronary artery bypass grafting (CABG). Usually, thyroid disorders pose very subtle symptoms that go unnoticed and remain undiagnosed for a long period of time. In this study, we analyze the effect of thyroid disorder (hypothyroid and hyperthyroid) on the clinical vitals, and pre-operative, intraoperative and post-operative parameters of the subjects who had undergone CABG. Our analysis establishes that thyroid disorders, if not controlled, can be indicators of poor outcomes in subjects undergoing CABG. Regular monitoring and maintenance of thyroid hormones is imperative in subjects undergoing CABG. [ABSTRACT FROM AUTHOR]

Aims To evaluate a self-administered digital education resource for patients after a heart attack (adapted simplified Chinese version of Cardiac College™) on secondary prevention knowledge and health behaviour change outcomes. Methods and results Chinese immigrants recovering from a heart attack were recruited from cardiac rehabilitation programmes at four metropolitan tertiary hospitals. Participants provided access to Cardiac College™ (adapted simplified Chinese version), a self-learning secondary prevention virtual education resource over 4 weeks. The web-based resources include 9 booklets and 10 pre-recorded video education sessions. Assessments included health literacy, secondary prevention knowledge, self-management behaviours, self-reported physical activity, and a heart-healthy diet. Satisfaction, acceptability, and engagement were also assessed. From 81 patients screened, 67 were recruited, and 64 (95.5%) completed the study. The participants' mean age was 67.2 ± 8.1 years old, 81.2% were males, and the majority had no English proficiency (65.6%). Following the intervention, significant improvements were observed for secondary prevention knowledge overall and in all subdomains, with the most improvement occurring in medical, exercise, and psychological domains (P < 0.001). Dietary and self-management behaviours also improved significantly (P < 0.05). According to participants, the educational materials were engaging (100%), and the content was adequate (68.8%); however, 26.6% found the information overwhelming. Overall, 46.9% were highly satisfied with the resources. Conclusion A self-learning virtual patient-education package improved secondary prevention knowledge and self-care behaviour in Chinese immigrants after a heart attack. The culturally adapted version of Cardiac College™ offers an alternative education model where bilingual staff or translated resources are limited. [ABSTRACT FROM AUTHOR]

This article examines the impact of risk stratification on cardiovascular outcomes in patients with stable chest pain. The study, conducted at the National Heart Centre Singapore, included 1658 patients who were classified based on their pre-test probability (PTP) of obstructive coronary artery disease (CAD) using risk scores. The findings indicate that patients with a low PTP had a favorable prognosis and low adverse clinical outcomes, suggesting that additional cardiac testing may be safely deferred in this group. The study also addresses the development of a risk prediction tool specifically for Southeast Asians, as the risk scores used in the study were originally developed for Western cohorts. The article emphasizes the importance of considering the outcomes of patients with stable chest pain and the potential benefits of reducing unnecessary testing, including the financial burden, anxiety, and false positive results associated with such testing.
