Rationale and design of a single-center randomized trial to compare the graft patency between the radial artery and the no-touch saphenous vein in coronary artery bypass grafting surgery (GRAFT-CAB Study)

Previous studies suggested only the radial artery and the No-touch (NT) technique were effective in reducing graft occlusion after coronary artery bypass grafting (CABG) surgery. However, there is no randomized trial comparing these 2 graft conduits. The optimum second conduit for CABG remains undetermined. This study is a prospective, single-center randomized clinical trial, aiming to compare the graft patency between the radial artery and the NT vein graft. All patients undergoing isolated CABG with left internal mammary artery (LIMA) plus at least 2 additional grafts will be considered eligible. About 774 cases (516 in the radial artery group and 258 in the NT vein group) will be enrolled in over 1 to 2 years. Participants will be randomized and allocated to two bypass strategies: the LIMA plus 1 radial artery and 1 conventional vein graft, or the LIMA plus 2 NT vein grafts. The primary outcome is graft occlusion at 1 year after CABG evaluated by CT angiography. The secondary outcomes include graft occlusion at 3 and 5 years and major adverse cardiac or cerebrovascular events at 1, 3, and 5 years follow-ups. This study will define whether or not the NT vein has a lower graft occlusion rate than the radial artery in short and mid-term follow-ups, and provide new evidence for the second conduit choice in CABG surgery.

Association between the geriatric nutritional risk index and clinical outcomes among peritoneal dialysis patients: A meta-analysis.

To identify the relationship between the geriatric nutritional risk index (GNRI) and clinical outcomes in patients receiving peritoneal dialysis (PD). The PubMed, EBASE, Web of Science and CNKI databases were searched for available studies up to December 25, 2023. The primary outcome was all-cause mortality, and the secondary outcomes included the incidence of PD dropout, major adverse cardiac and cerebrovascular events (MACCEs), technique failure and peritonitis. Hazard ratios (HRs) and 95% confidence intervals (CIs) were combined to evaluate the predictive value of the GNRI for the occurrence of the above endpoints. Ten cohort studies with 3897 patients were included. The pooled results demonstrated that a lower GNRI was significantly associated with a greater incidence of all-cause mortality (HR = 0.71, 95% CI: 0.55-0.91; P = .007). In addition, a decreased GNRI predicted the occurrence of dropout from PD (HR = 0.971, 95% CI: 0.945-0.998, P = .034) and MACCE (HR = 0.95, 95% CI: 0.92-0.98, P = .001). However, no significant associations of the GNRI with technique failure (P = .167) or peritonitis (P = .96) were observed. A low GNRI is significantly associated with poor clinical outcomes and might serve as a novel and valuable prognostic indicator among PD patients.

Incidence of Complications in Obese Patients Undergoing Elective Spine Surgery Under General Anesthesia: A Retrospective Study

Abstract Background The prevalence of obesity has been increasing worldwide. Simultaneously, the number of obese patients undergoing anesthesia and the risk of anesthesia-related complications are increasing. Our study aimed to identify the incidence of intraoperative anesthetic complications in obese patients undergoing elective spine surgery. Methods Electronic medical records of patients with a body mass index (BMI) ≥ 30 kg/m2 who underwent elective spine surgery at the Neurological Institute of Thailand between January 2018 and December 2020 were retrospectively reviewed. The primary outcome was the incidence of five anesthetic adverse events: difficult intubation, oxygen desaturation, hypotension, major adverse cardiac and cerebrovascular events (MACCE), and pressure skin lesions. Logistic regression was used for statistical analysis. Results A total of 165 obese patients' medical records were analyzed. Their mean age was 56.8 ± 11.9 years, and median BMI (interquartile range) was 32.04 kg/m2 (31.11–34.69 kg/m2). Fifty-one patients (30.9%) experienced adverse events. Six patients (3.6%) with class 3 obesity had anesthetic complications. The most common adverse event was intraoperative hypotension (26.7%), followed by pressure skin lesions (4.2%), intraoperative oxygen desaturation (1.2%), and MACCE (0.6%). No difficult intubations or deaths occurred. Conclusion The incidence of overall intraoperative anesthetic complications in obese patients undergoing spine surgery was 30.9%, and class 3 obesity was an independent risk factor for these complications. Consequently, well-trained, vigilant, and experienced anesthesiologists should manage anesthesia in these patients.

Long-Term Implications of Socioeconomic Status on Major Adverse Cardiovascular, Cerebrovascular Events (MACCE), and All-Cause Mortality

Socio-economic status (SES) has a large impact on health through a complex interplay of upstream, midstream and downstream factors. However, little is known about the predictive role of SES on long-term major adverse cardiovascular, cerebrovascular events, and mortality (MACCE). To determine the long-term relationship between SES and MACCE for men and women. The secondary endpoint was to determine the relationship between SES and all-cause mortality. A total of 3,034 participants (1,494 women and 1,540 men) were assessed at baseline in the Geelong Osteoporosis Study, a large regional Australian population cohort study. Area-based SES was assessed, utilising the Index of Relative Socio-Economic Disadvantage (IRSD) and grouped into quintiles. The primary endpoint, MACCE, was defined as a composite of myocardial infarction, heart failure hospitalisation, malignant arrhythmias, stroke, and all-cause mortality. The secondary endpoint was all-cause mortality. Baseline data including age, sex, smoking status and alcohol use, and comorbidities were collected between 1993-1997 for women, and 2001-2006 for men, with follow-up over 30 and 22 years, respectively. Logistic regression was utilised to assess MACCE and all-cause mortality outcomes across the SES quintiles. Participants lost to follow-up or with incomplete data collection were excluded leaving 2,173 participants eligible for analysis. SES was associated with MACCE outcomes. Compared with Quintile I (lowest SES stratum), the odds of MACCE for each IRSD stratum were: Quintile II, odds ratio (OR) 0.85 (95% confidence interval [CI] 0.65-1.13); Quintile III, OR 0.69 (95% CI 0.51-0.91); Quintile IV, OR 0.66 (95% CI 0.50-0.88); and, Quintile V, OR 0.55 (95% CI 0.41-0.72). In the adjusted model, an inverse trend was noted, with reducing MACCE outcomes with an increasing SES status; IRSD Quintile II, OR 0.85 (95% CI 0.62-1.17); Quintile III, OR 0.70 (95% CI 0.50-0.97); Quintile IV, OR 0.73 (95% CI 0.52-1.02); and, Quintile V, OR 0.54 (95% CI 0.39-0.74). SES was inversely associated with all-cause mortality; IRSD Quintile II (OR 0.87, 95% CI 0.66-1.16) failed to achieve significance however IRSD Quintile III (OR 0.65, 95% CI 0.48-0.88), Quintile IV (OR 0.59, 95% CI 0.44-0.80) and Quintile V (OR 0.46, 95% CI 0.34-0.62) had a lower risk of mortality compared with Quintile I. In the adjusted model, an inversely proportional trend was noted between SES and all-cause mortality; IRSD Quintile II (OR 0.82, 95% CI 0.59-1.15), IRSD Quintile III (OR 0.63, 95% CI 0.49-0.95), Quintile IV (OR 0.59, 95% CI 0.45-0.90) and Quintile V (OR 0.44, 95% CI 0.31-0.61) had fewer mortality events compared with IRSD Quintile I. Our research indicates that being part of a lower socio-economic stratum is linked to a higher likelihood of experiencing negative cardiovascular and cerebrovascular events, along with an increased risk of overall mortality. SES is an important risk stratification marker for long-term prognosis of cardiovascular diseases and stroke, and warrants further investigation.

Predictive Value of Plasma PCSK9 Levels for Degree of Atherosclerosis and Major Adverse Cardiovascular and Cerebrovascular Events in Older Adult Patients with Non-Alcoholic Fatty Liver Disease.

This study investigated the influence of plasma proprotein convertase subtilisin/kexin 9 (PCSK9) levels on the degree of atherosclerosis and major adverse cardiovascular and cerebrovascular events (MACCE) in older adults with non-alcoholic fatty liver disease. The degree of atherosclerosis severity was assessed by the standard Gensini score quartile method. According to the degree of atherosclerosis, patients were divided into mild (0-24 points; n=84), moderate (25-53 points; n=86), and severe groups (≥54 points; n=84) and then categorized as MACCE (n=30) or non-MACCE (n=224) according to 6-month follow-up data. The patients' age, sex, smoking history, medical history, and early morning fasting venous blood, for measuring biochemical indexes, were collected. Clinical data were compared between groups and the relationship between Gensini scores and PCSK9 was evaluated. Compared with the mild group, the moderate and severe groups had higher high-sensitivity C-reactive protein(hs-CRP), PCSK9, triglycerides(TG), low-density lipoprotein cholesterol (LDL-C), and lipoprotein(a)[Lp(a)] levels and lower high-density lipoprotein cholesterol(HDL-C) levels (all P<0.05). Moreover, PCSK9 positively correlated with Gensini scores (r=0.657, P<0.01). The MACCE and non-MACCE groups had significantly different ages, statin use, Gensini scores, PCSK9, and LDL-C (all P<0.05). Multi-factorial Cox risk regression analysis showed the Gensini score (HR=1.018, 95% CI: 1.006~1.029) and PCSK9 (HR=1.147, 95% CI: 1.038~1.287) were independent risk factors for MACCE. The Gensini score and PCSK9 levels can be used as predictive indicators for the degree of illness and occurrence of MACCE in older NAFLD patients.

The Impact of Microvascular Resistance Reserve on the Outcome of Patients With STEMI

BackgroundMicrovascular resistance reserve (MRR) can characterize coronary microvascular dysfunction (CMD); however, its prognostic impact in ST-segment elevation myocardial infarction (STEMI) patients remains undefined. ObjectivesThis study sought to investigate the prevalence of CMD in STEMI patients and to elucidate the prognostic performance of MRR. MethodsThis prospective cohort study enrolled 210 STEMI patients with multivessel disease who underwent successful revascularization and returned at 3 months for coronary physiology assessments with bolus thermodilution. The prevalence of CMD (MRR <3) and the association between MRR and major adverse cardiovascular and cerebrovascular events (MACCEs) at 12 months were investigated. ResultsThe median age of patients was 65 years, and 59.5% were men. At the 3-month follow-up, 56 patients (27%) had CMD (MRR <3.0). The number of MACCEs at 12 months was higher in patients with vs without CMD (48.2% vs 11.0%; P < 0.001). MRR was independently associated with 12-month MACCEs (HR: 0.45 per unit increase; 95% CI: 0.31-0.67; P < 0.001) and with stroke, heart failure, and poorer recovery in left ventricular systolic function. The areas under the receiver-operating characteristic curves for predicting MACCEs at 12 months with fractional flow reserve, coronary flow reserve (CFR), the index of microvascular resistance (IMR), and MRR were 0.609, 0.762, 0.781, and 0.743, respectively. The prognostic performance of CFR, IMR, and MRR were all comparable. ConclusionsThe novel parameter MRR is a prognostic marker of MACCEs in STEMI patients with a comparable performance to CFR and IMR.

OBSTRUCTIVE SLEEP APNEA REMAINS A RISK FACTOR FOR MAJOR ADVERSE CARDIOVASCULAR AND CEREBROVASCULAR EVENTS IN HYPERTENSVIE PATIENTS UNDER TREATMENT: THE UROSAH DATA

Objective: The impact of the co-occurrence of hypertension and obstructive sleep apnea (OSA) on the risk of long-term cardiovascular disease (CVD) outcomes has not been extensively studied in the Asian population, and the residual effect of OSA on CVD in patients under antihypertensive treatment is not clear. The study aimed to explore the impact of OSA on the risk of CVD outcomes in a large-scale Asian cohort under antihypertensive treatment using retrospective design. Design and method: Hypertensive patients who underwent polysomnography (PSG) test in January 2011 to December 2013 were recruited from the UROSAH cohort, which was conducted in Hypertension Center of People's Hospital. OSA was defined as apnea hypopnea index over 5. Outcomes were extended major adverse cardiovascular and cerebrovascular events (MACCE), including the first occurrence of nonfatal myocardial infarction, nonfatal stroke, revascularization, rehospitalization due to unstable angina or heart failure and all-cause death. Cox regression analysis was performed to explore the effect of OSA and hypertension coexistence on MACCE. Results: A total of 3329 hypertension patients were enrolled, of whom 2585 patients (about 77.7%) suffered from OSA. During a median follow-up period of 7.0 years, 415 patients developed extended MACCE. The incidence of extended MACCE was significantly greater in patients with OSA than those without OSA (hazard ratio [HR]: 1.59; 95% confidence interval [CI]: 1.27-1.99; P&lt;0.001). Overall, patients with OSA had an increased risk of cardiac events of 57% compared to those without OSA [HR (95%CI): 1.57 (1.04-2.39), P=0.034] and the association did not change in further sensitivity analysis. Particularly in uncontrolled hypertension, OSA was found to have a 93% increased risk of cardiac events, compared with patients without OSA (P=0.036). Conclusions: Untreated OSA seemed to be a factor affecting the prognosis of cardiac events in hypertensive patients, although the association between OSA and cardiac events would be attenuated by the pharmacological-induced blood pressure control, which highlights the need to treat OSA.

The Long-Term Prognostic Role of Nighttime Resting Heart Rate in Obstructive Sleep Apnea in Patients with Acute Coronary Syndrome.

A close relationship exists between resting heart rate (RHR) and obstructive sleep apnea (OSA). Still, the prognostic importance of nighttime RHR in patients with acute coronary syndrome (ACS) with or without OSA remains unclear. In this prospective cohort study, OSA was defined as an apnea-hypopnea index of ≥ 15 events/h, and the high nighttime RHR (HNRHR) was defined as a heart rate of ≥ 70 bpm. The primary endpoint was a major adverse cardiovascular and cerebrovascular event (MACCE), including cardiovascular death, myocardial infarction, stroke, ischemia-driven revascularization, or hospitalization for heart failure. Among the 1875 enrolled patients, the mean patient age was 56.3±10.5 years, 978 (52.2%) had OSA, and 425 (22.7%) were in HNRHR. The proportion of patients with HNRHR is higher in the OSA population than in the non-OSA population (26.5% vs. 18.5%; P＜0.001). During 2.9 (1.5, 3.5) years of follow-up, HNRHR was associated with an increased risk of MACCE in patients with OSA (adjusted HR: 1.56, 95% CI: 1.09-2.23, P=0.014), but not in patients without OSA (adjust HR: 1.13, 95% CI: 0.69-1.84, P=0.63). In patients with ACS, a nighttime RHR of ≥ 70 bpm was associated with a higher risk of MACCE in those with OSA but not in those without it. This identifies a potential high-risk subgroup where heart rate may interact with the prognosis of OSA. Further research is needed to determine causative relationships and confirm whether heart rate control impacts cardiovascular outcomes in patients with ACS-OSA.

ASSOCIATION BETWEEN OFFICE BLOOD PRESSURE AND LONG-TERM CLINICAL EVENTS IN PATIENTS WITH CORONARY ARTERY DISEASE AFTER PERCUTANEOUS CORONARY INTERVENTION

Objective: The optimal blood pressure (BP) target for patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) remains unclear. This study aimed to identify the optimal BP target by investigating the association between average office BP and future clinical events after PCI in patients with CAD. Design and method: Consecutive patients undergoing PCI from 2012 to 2016 were included. They were divided into five groups according to the average follow-up BP after discharge. The co-primary outcome was major adverse cardiac and cerebrovascular event (MACCE: all-cause death, non-fatal myocardial infarction, non-fatal stroke, or any revascularization) and net adverse clinical events (NACE: MACCE, or major bleeding) up to 5 years. Results: A total of 2,845 patients were included in the analyses, and among them, 787 (27.7%) experienced the NACE during the follow-up period. Patients in the highest SBP group (adjusted hazard ratio [HR] 1.495, confidence interval [CI] 1.189–1.880) and lowest SBP group (adjusted HR 1.625, CI 1.214–2.176) had a significantly higher risk of 5-year NACE. Similar associations were observed between SBP and the risk of MACCE, and similar results based on DBP categories were also observed. There was a J-curve relationship observed between SBP and DBP with respect to 5-year NACE and MACCE. The nadir point of risk for NACE and MACCE was found at 121.4/74.8 and 120.4/73.7 mmHg. Conclusions: In patients underwent PCI, there is a significant correlation between office BP level and clinical events, which indicates the importance of efforts for optimal BP control to reduce ischemic and bleeding events.

The Predictive Value of Geriatric Nutritional Risk Index Combined with the GRACE Score in Predicting the Risk of One Year Poor Prognosis in Elderly Patients with Non-ST Segment Elevation Myocardial Infarction After PCI.

As a nutritional indicator, a lower level of geriatric nutritional risk index (GNRI) has been suggested as a predictor for poor prognosis in acute coronary syndrome (ACS). However, whether GNRI could improve the predictive value of the Global Registry of Acute Coronary Events (GRACE) score for the prognosis in elderly patients with non-ST segment elevation myocardial infarction (NSTEMI) after PCI remains unclear. A total of 446 elderly patients with NSTEMI after percutaneous coronary intervention (PCI) were consecutively enrolled. Patients were divided into major adverse cardiovascular and cerebrovascular events (MACCE) group and control group according to the occurrence of MACCE during one year follow up. The clinical parameters including GNRI were compared to investigate the predictors for MACCE. The performance after the addition of GNRI to the GRACE score for predicting MACCE was determined. A total of 68 patients developed MACCE. In unadjusted analyses, the rate of MACCE was significantly higher in the 93.8<GNRI <102.7 group and GNRI ≤ 93.8 group versus GNRI ≥ 102.7 group. The logistics regression model showed that age, GNRI, and GRACE score were independent predictors for MACCE in elderly patients with NSTEMI after PCI. The addition of the GNRI to the GRACE score significantly improved the prediction of MACCE in elderly patients with NSTEMI after PCI, increasing the C-index from 0.792 to 0.885 (p < 0.001); the NRI was 0.094 (95% CI, 0.004-0.177, p < 0.001), and the IDI was 0.011 (95% CI, 0.000-0.023, p < 0.001). Combining GNRI and GRACE score could significantly improve the predictive value of one year MACCE in elderly patients with NSTEMI after PCI. By using this combined new risk model, we could easily identify the high-risk populations in clinical practice, so as to better monitor and manage them.

Clinical Outcomes of Surgical Revascularization Strategies Guided by Quantitative Flow Ratio in Primary Noncoronary Cardiac Surgery.

Information regarding quantitative flow ratio (QFR) usage in coronary artery bypass grafting (CABG) is lacking. We compared the incidence of postoperative long-term adverse cardiovascular and cerebrovascular events after QFR-guided or coronary angiography-guided adult cardiac surgery with concurrent bypass surgery. This study included 432 patients who underwent cardiopulmonary bypass (CPB) at our institution with at least 1 angiographical coronary artery lesion (diameter stenosis: 30% to 90%) between January 2015 and January 2016. The QFR of each patient was calculated. Patients who only underwent intraoperative coronary revascularization following the principles of optimal revascularization strategy were assigned to group A. Patients with coronary lesions not meeting the above criteria were placed in group B. The average number of distal anastomoses of patients with combined CABG in group B was similar to that in Group A (1.9±1.0 vs. 1.7±0.9; P =0.081). Group A had a shorter CPB duration (114.4±49.2 vs 135.8±55.2 minutes; P <0.001) and shorter aortic cross-clamping time (83.6±36.2 vs 101.1±40.6 minutes; P <0.001). The rates of perioperative mortality and major complications did not differ between groups. Long-term major adverse cardiovascular and cerebrovascular events (MACCEs) were less common in group A than in group B (14.7% vs 29.5%; P <0.001). In primary noncoronary cardiac surgery, despite the similar average numbers of distal anastomoses, the group with target vessels treated using an optimal coronary revascularization strategy presented shorter CPB time and aortic cross-clamping time than the other group. Multivariate analyses also showed a lower incidence of long-term MACCEs.

The prognostic impact of insulin resistance surrogates in patients with acute myocardial infarction with and without type 2 diabetes.

Cardiovascular disease is the major cause of morbidity and mortality, particularly in type 2 diabetes mellitus (T2DM). Novel markers of insulin resistance and progression of atherosclerosis include the triglycerides and glucose index (TyG index), the triglycerides and body mass index (Tyg-BMI) and the metabolic score for insulin resistance (METS-IR). Establishing independent risk factors for in-hospital death and major adverse cardiac and cerebrovascular events (MACCE) in patients with myocardial infarction (MI) remains critical. The aim of the study was to assess the risk of in-hospital death and MACCE within 12months after ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI) in patients with and without T2DM based on TyG index, Tyg-BMI and METS-IR. Retrospective analysis included 1706 patients with STEMI and NSTEMI hospitalized between 2013 and 2021. We analyzed prognostic value of TyG index, Tyg-BMI and METS-IR for in-hospital death and MACCE as its components (death from any cause, MI, stroke, revascularization) within 12months after STEMI or NSTEMI in patients with and without T2DM. Of 1706 patients, 58 in-hospital deaths were reported (29 patients [4.3%] in the group with T2DM and 29 patients [2.8%] in the group without T2DM; p = 0.1). MACCE occurred in 18.9% of the total study population (25.8% in the group with T2DM and 14.4% in the group without T2DM; p < 0.001). TyG index, Tyg-BMI and METS-IR were significantly higher in the group of patients with T2DM compared to those without T2DM (p < 0.001). Long-term MACCE were more prevalent in patients with T2DM (p < 0.001). The area under the ROC curve (AUC-ROC) for the prediction of in-hospital death and the TyG index was 0.69 (p < 0.001). The ROC curve for predicting in-hospital death based on METS-IR was 0.682 (p < 0.001). The AUC-ROC values for MACCE prediction based on the TyG index and METS-IR were 0.582 (p < 0.001) and 0.57 (p < 0.001), respectively. TyG index was an independent risk factor for in-hospital death in patients with STEMI or NSTEMI. TyG index, TyG-BMI and METS-IR were not independent risk factors for MACCE at 12month follow-up. TyG index and METS-IR have low predictive value in predicting MACCE within 12months after STEMI and NSTEMI.

Predicting outcomes in patients with low ejection fraction undergoing coronary artery bypass graft

IntroductionReduced left ventricular ejection fraction (LVEF) is a well-known predictor of adverse events after cardiac surgery. We aimed to assess the outcomes in patients with low LVEF undergoing coronary artery bypass graft. MethodsIn this retrospective cohort, we included all patients with left ventricular ejection fraction ≤ 40 who underwent coronary artery bypass grafting between March 2007 and March 2016 (with a median follow-up of nine years) at Tehran Heart Center. Demographics and clinical characteristics were extracted from the data registry. Akaike information criterion (AIC) was used. The univariate Cox regression was performed. We investigated the predictors of mortality and major adverse cardiac and cerebrovascular events (MACCE) using Cox multivariable regression. ResultsIn total, 5,532 cases (79 % male) with a mean age of 65.58 were included in the study. The nine-year overall survival was calculated at 68 %, and more than half of the patients had MACCE (55 %). In adjusted multivariable Cox regression analysis, moderate to severe mitral valve regurgitation, glomerular filtration rate ≤ 60, mild right ventricular dysfunction, and valvular heart disease independently predicted higher mortality. The abovementioned predictors and peripheral vascular disease significantly increased MACCE. ConclusionOur study indicates the clinical significance of mitral regurgitation, valvular heart disease, and renal function in patients with low ejection fraction treated by coronary artery bypass grafting surgery. Identifying predictors of adverse events can help with clinical decision-making and risk stratification, ultimately improving patient outcomes.

Readmission Trends and Outcomes of Transcatheter Edge-to-Edge Repair of Mitral Regurgitation With and Without Anemia.

Anemia is associated with worse clinical outcomes in cardiac patients. We aim to investigate the clinical outcomes and readmission rates in anemic patients undergoing transcatheter edge-to-edge repair (TEER) for severe mitral valve regurgitation (MR). The National Readmissions Database (NRD) from 2015 to 2018 was queried using the ICD-10 codes to identify patients admitted for TEER. Patients were divided into anemic and non-anemic sub-groups. Univariate and multivariate analyses were performed. Cardiovascular outcomes were assessed between cohorts at index admission and readmissions at 30, 90, and 180 days. STATA v.17 was used for analysis (StataCorp LLC, Texas, USA). Our final cohort included 28,995 patients who had undergone TEER in the United States between 2016 and 2019. About 1,434 (4.9%) had a diagnosis of anemia. The mean age of patients who had TEER with anemia and TEER without anemia was 76.9 ± 10.8 vs. 77.7 ± 10.2, respectively. In the adjusted model, anemic patients had higher odds of acute kidney injury (AKI) (aOR 2.21; 95% [CI 1.81-2.6; p<0.001]), HF (aOR 1.75; 95% [CI 1.28-2.3; p<0.001]), myocardial infarction (MI) (aOR 1.54; 95% [CI 1.01-2.33; p<0.041]), major adverse cardiac and cerebrovascular events (MACCE) (aOR 1.72; 95% [CI 1.2-9-2.3; p<0.001]), and net adverse event (aOR 1.85; 95% [CI 1.32-2.59; p<0.001]). The anemic group's readmission rate was overall higher at 30, 90, and 180 days from 2016 to 2019. Anemia was associated with increased adverse clinical outcomes and more extended hospital stays in patients with anemia who had undergone TEER procedures compared to the non-anemic group.

Effect of delayed hospitalization on 3-year clinical outcomes according to renal function in patients with non-ST-segment elevation myocardial infarction.

We evaluated the effect of delayed hospitalization (symptom-to-door time [STD] ≥ 24 h) on 3-year clinical outcomes according to renal function in patients with non-ST-segment elevation myocardial infarction (NSTEMI) undergoing new-generation drug-eluting stent (DES) implantation. A total of 4513 patients with NSTEMI were classified into chronic kidney disease (CKD) (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73 m², n = 1118) and non-CKD (eGFR ≥ 60 mL/min/1.73 m², n = 3395) groups. They were further sub-classified into groups with (STD ≥ 24 h) and without (STD < 24 h) delayed hospitalization. The primary outcome was the occurrence of major adverse cardiac and cerebrovascular events (MACCE), defined as all-cause death, recurrent myocardial infarction, any repeat coronary revascularization, and stroke. The secondary outcome was stent thrombosis (ST). After multivariable-adjusted and propensity score analyses, the primary and secondary clinical outcomes were similar in patients with or without delayed hospitalization in both CKD and non-CKD groups. However, in both the STD < 24 h and STD ≥ 24 h groups, MACCE (p < 0.001 and p < 0.006, respectively) and mortality rates were significantly higher in the CKD group than in the non-CKD group. However, ST rates were similar between the CKD and non-CKD groups and between the STD < 24 h and STD ≥ 24 h groups. Chronic kidney disease appears to be a much more important determinant of MACCE and mortality rates than STD in patients with NSTEMI.

Impact of initial high sensitivity C-reactive proteinon outcomes in nonvalvular atrial fibrillation: an observational study.

Aim: The index study aimed to investigate the clinical impact of initial high-sensitivity C-reactive protein (hs-CRP) on outcomes in nonvalvular atrial fibrillation (AF). Methods: Single-center, prospective, observational study recruiting all recently diagnosed treatment-naive AF patients. Hs-CRP was measured at baseline and patients were followed for 24months. Results: A total of 126 patients with a mean age of 66.2 (±12.0) years were enrolled. The composite outcome of major adverse cardiac or cerebrovascular events (MACCE) occurred in 19 (17.7%) at 24months. Raised initial hs-CRP emerged as an independent predictor of MACCE on regression analysis (OR: 1.569, 95% CI: 1.289-1.912; p<0.001). Conclusion: Raised hs-CRP was an independent predictor of MACCE at 24months. It allows for early identification of high-risk patients.

Long-Term Effects of Opium Consumption Following Percutaneous Coronary Intervention: A 10-year Follow-Up Study.

Opium consumption has been an overlooked health issue in the Iranian population, and the prognostic role of opium consumption in patients undergoing coronary revascularization is unknown. We aimed to assess the association between opium consumption and long-term cardiovascular outcomes after percutaneous coronary intervention (PCI). We screened 2203 consecutive patients who underwent elective PCI between April 2009 and April 2010 at Tehran Heart Center. Exclusion criteria were unsuccessful PCI, non-elective PCI, and missing opium use data. Opium consumption was defined as self-reported ever use of any traditional opium substances. Outcomes of interest were all-cause mortality and a composite of major adverse cardiac and cerebrovascular events (MACCE). The association between opium use and study outcomes was evaluated using the inverse probability of treatment weighting (IPTW) method. Cumulative hazard curves were demonstrated to further assess the association visually. Furthermore, the effect of opium consumption on individual components of MACCE was evaluated in a competing risk setting. A total of 2025 elective PCI patients were included (age: 58.7 ± 10.67, 29.1% women), among whom 297 (14.6%) patients were opium users. After a median follow-up of 10.7 years, opium consumption was associated with a higher risk of all-cause mortality (IPTW-hazard ratio [HR] = 1.705, 95% CI: 1.125-2.585; P = 0.012) and MACCE (IPTW-HR = 1.578, 95% CI: 1.156-2.153; P = 0.004). The assessment of MACCE components suggested a non-significant borderline trend for higher non-fatal myocardial infarction (IPTW-sub-distribution HR [SHR] = 1.731, 95% CI: 0.928-3.231; P = 0.084) and mortality (IPTW-SHR = 1.441, 95% CI: 0.884-2.351; P = 0.143) among opium users. Opium consumption is associated with a more than 50% increase in long-term risk of mortality and MACCE in patients undergoing PCI. These findings accentuate the importance of preventive strategies to quit opium addiction in this population.

Perioperative cardiovascular and cerebrovascular outcomes in recipients of ECMO bridge to lung transplant

BackgroundThe use of ECMO as bridge to lung transplant (BTT) has increased over time. While one-year and overall survival have been reported to be similar with non-ECMO transplant recipients, there are limited data major adverse cardiovascular and cerebrovascular events (MACCE) and clinically relevant bleeding (CRB) events. In this study we sought to evaluate the incidence of perioperative MACCE and CRB in lung transplant recipients who underwent ECMO BTT. MethodsUsing the National Inpatient Sample from 2008 to 2019, we identified 5,254 lung transplant recipients who either received or did not require pre-transplant ECMO. Perioperative MACCE and CRB were compared between the two cohorts. ResultsPatients with ECMO BTT had a higher incidence of MACCE compared to non-ECMO patients (35% vs. 13.3%, p <0.0001) and CRB (34.5% vs 12.9%, p <0.0001). Recipients of pre-transplant ECMO for double lung transplant (n=158) were more likely to have perioperative MACCE and CRB as opposed to patients without pre-transplant ECMO (n=3,584) (adjusted odds ratio 2.69, p <0.0001; 95% CI 1.86-3.80). The ECMO BTT cohort were notably younger with less cardiac comorbidities and higher diagnoses of cystic fibrosis and ILD. ConclusionOur data indicate that lung transplant recipients who required ECMO BTT are at significantly higher risk of MACCE and bleeding events despite being younger with less comorbidities as opposed to those who did not require ECMO.

Long-term outcomes of myocardial revascularization in patients with multivessel coronary artery disease and comorbid pathology

&lt;b&gt;Objective:&lt;/b&gt; To assess the long-term outcomes of myocardial revascularization in patients with multivessel coronary artery disease and varying degrees of comorbidity.&lt;br /&gt; &lt;b&gt;Materials and methods:&lt;/b&gt; 406 patients with low and moderate Syntax scores (SS) (&amp;lt;33) underwent primary percutaneous coronary intervention (PCI) (n=200) with a drug-eluting stent, and coronary artery bypass grafting (CABG) (n=206). Patients were stratified by the Charlson Comorbidity Index (CCI) into 2 groups: 1) CCI ≤ 3(n=108/26.6%); 2) CCI ≥ 4(n=298/73.4%). The mean follow-up period was 9±1.9 years. The endpoints of the study were as follows: major adverse cardiac and cerebrovascular events (МАССЕ), a repeat revascularization, decreased left ventricular ejection fraction, and high SS in dynamics.&lt;br /&gt; &lt;b&gt;Results:&lt;/b&gt; An increase in CCI of more than 4 points was significantly associated with the risk of developing a combination of MACCE (HR 1.3, CI 1.2 – 1.4, p&amp;lt;0.001), all-cause mortality (HR 1.3, CI 1.2 – 1.4, p&amp;lt;0.001), and cerebrovascular accidents (CVA) (HR 2.2, CI 1.4 – 3.4, p=0.001). Patients with CCI ≥4 required repeat revascularization more frequently after PCI than after CABG (HR 2.6, CI 1.8 – 3.7, p&amp;lt;0.001). Among patients with varying degrees of comorbidity, the risk of progression of coronary atherosclerosis (SS≥33) was higher after CABG compared with PCI.&lt;br /&gt; &lt;b&gt;Conclusion:&lt;/b&gt; A CCI score of more than 4 points was associated with an increased risk of developing of MACCE, all-cause mortality, and CVA. Among patients with varying degrees of comorbidity, PCI and CABG did not demonstrate significant advantages in terms of MACCE.

Effects of temporal changes in resting heart rate on future diabetes-related outcomes.

Most studies have analyzed the relationship between resting heart rate (RHR) measured at only one time point and future clinical events. The current study aims to investigate the impact of long-term RHR changes on future clinical outcomes in a decade-long cohort with type 2 diabetes mellitus (T2DM). The two-staged follow-up involved 2,513 T2DM participants. The first stage (2008-2014) intended to identify levels and trends in RHR changes, while the second stage (2014-2018) attempted to collect new occurrence records of clinical results. Cox proportional hazards models were applied to predict hazard ratios (HRs), along with 95% confidence interval (CI) for the correlation between RHR changes and future events. There is no significant correlation between baseline RHR levels and long-term clinical events. According to the range of RHR change, compared with the stable RHR group, the adjusted HRs for cardiovascular events and all-cause death in the large increase group were 3.40 (95% CI: 1.33-8.71, p=0.010) and 3.22 (95% CI: 1.07-9.64, p=0.037), respectively. While the adjusted HRs for all-cause death and major adverse cardiac and cerebrovascular events (MACCE) in the moderate decrease group were 0.55 (95% CI: 0.31-0.96, p=0.037) and 0.51 (95% CI: 0.26-0.98, p=0.046). According to the trend of RHR, compared with the normal-normal group, the adjusted HRs for composite endpoint events and cerebrovascular events in the normal-high group were 1.64 (95% CI: 1.00-2.68, p=0.047) and 2.82 (95% CI: 1.03-7.76, p=0.043), respectively. Changes in RHR had predictive value for long-term clinical events in diabetic populations. Individuals with significantly elevated RHR over a particular period of time showed an increased risk of adverse events.
