Background/aim: Patients with atrial fibrillation (AF) and coronary stenting had a poor prognosis. This study aimed to assess the accuracy of CHA2DS2-VASc score for predicting and grading adverse clinical outcomes in this population. Materials and methods: We reviewed the clinical data of all patients with previously documented nonvalvular AF who underwent coronary stenting between January 2010 and June 2015 in 12 hospitals of Beijing, China. The study population was divided into three groups: 1) Low CHA2DS2-VASc score, ≤ 2 points, 2) Intermediate score, 3-4 points, and 3) High score, ≥ 5 points. Major adverse cardiac/cerebrovascular events (MACCE) were defined as a composite of all-cause death, nonfatal myocardial infarction, repeat revascularization and ischemic stroke/systemic thromboembolism (IS/SE). Results: A total of 2394 patients (men: 72.3% vs. women: 27.7%, median age: 67 years) were included, with the CHA2DS2-VASc score of 3.6 ± 1.6. The median follow-up duration was 36.2 months. All-cause mortality increased 3 folds from the low score (4.8%) to the high score group (15.8%). The high score group had more IS/SE (7.4%) and MACCE (26.3%). The CHA2DS2-VASc score ≥ 5 points was independently associated with all-cause death (hazard ratio [HR]: 2.303, 95% confidence interval [CI]: 1.492-3.555), IS/SE (HR: 4.169, 95% CI: 2.216-7.845) and MACCE (HR: 1.468, 95% CI: 1.113-1.936) on multivariate Cox proportional hazards regression. The area under the receiver operating characteristic curve of the CHA2DS2-VASc score was 0.644 (95% CI: 0.624-0.663) for all-cause death, 0.647 (95% CI: 0.627-0.666) for IS/SE, and 0.592 (95% CI: 0.572-0.611) for MACCE. Conclusion: CHA2DS2-VASc score was a reliable prognostic indicator in patients with AF and coronary stenting. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate predictors for adverse cardiovascular outcomes in patients with atrial fibrillation (AF) undergoing coronary stenting. We retrospectively recruited consecutive patients with previously documented non-valvular AF who underwent coronary stenting between January 2010 and June 2015 in 12 hospitals of Beijing, China. Major adverse cardiac/cerebrovascular events (MACCE) were a composite of all-cause death, non-fatal myocardial infarction, repeat revascularization, and ischaemic stroke/systemic thromboembolism (IS/STE). Major bleeding referred to grade 2 or higher of Bleeding Academic Research Consortium criteria. A total of 2394 patients (men: 72.3% vs. women: 27.7%, median age: 67 years) were included. The CHA2DS2-VASc and HAS-BLED were 3.6 ± 1.6 and 1.9 ± 0.7, respectively. The median follow-up duration was 36.2 months. There were 230 (9.6%) deaths, 96 (4.0%) IS/STE, 426 (17.8%) MACCE, and 72 (3.0%) major bleeding. Multivariate Cox regression yielded predictive models for (1) all-cause death: diabetes, prior myocardial infarction, chronic kidney disease (CKD), ST-segment elevation myocardial infarction (STEMI) at presentation, heart failure, no use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and statins; (2) IS/STE: advanced age, prior history of ischaemic stroke and intracranial haemorrhage; (3) MACCE: prior history of myocardial infarction and ischaemic stroke, CKD, STEMI, heart failure, and no statin use; (4) major bleeding: prior major bleeding, prior myocardial infarction, CKD and use of oral anticoagulants. Chinese patients with AF and coronary stenting had high mortality and incidence of MACCE. We compiled separate predictive models for all-cause death, IS/STE, MACCE, and major bleeding.

Objective: Sex differences in the clinical outcomes of patients with atrial fibrillation (AF) and coronary stenting should be assessed according to age. Methods: We analyzed the clinical data of all patients with nonvalvular AF who underwent coronary stenting between January 2010 and June 2015 in 12 hospitals of Beijing, China. Results: A total of 2,146 patients (71.8% men and 28.2% women) were included in the study. The mean age of the patients was 66.6±9.4 years. Women in this study were older and had higher prevalence of hypertension, diabetes, chronic kidney disease (CKD), and anemia. Smoking history was found to be higher in men, and women were less likely to be current smokers. The mean follow-up duration was 39.7 months. Women younger than 65 years had a remarkably higher mortality (11.2% vs. 5.3%, p=0.012) and a significantly lower rate of repeat revascularization (1.6% vs. 6.3%, p=0.034) than men. Female gender remained an independent predictor for all-cause mortality [hazard ratio (HR)=2.03, 95% confidence interval (CI): 1.09-3.79, p=0.025], along with heart failure (HR=3.64, 95% CI: 2.02-6.57, p<0.001) and CKD (HR=2.46, 95% CI: 1.09-5.57, p=0.031) after multivariate regression analysis. No significant difference was noted between men and women with regard to mortality, ischemic events, and major bleeding in elderly patients. Conclusion: In Chinese patients younger than 65 years with AF and coronary stenting, female gender was independently associated with increased mortality; men were more likely to receive repeat revascularization possibly due to the current smoking. Whether it was a biological difference or a recognition disparity of the disease between men and women warrants further investigation. [ABSTRACT FROM AUTHOR]
