Abstract:
Objective To explore the risk factors for sudden cardiac death(SCD)after revascularization in patients with coronary heart disease and heart failure.Methods This study was a retrospective analysis of 1683 patients with coronary heart disease whose left veatricalar ejection fraction(LVEF)≤40％within 30 days before revascularization.Patients were categorized into 2 groups according their clinical outcome as with or without SCD.Their clinical,angiographic and echocardiographic characteristics were reviewed and compared.The average follow-up time was 1803 days.Results There were total 59 SCD cases.The Cox regression analysis revealed that tricuspid regurgitation(HR 2.217,95％CI 1.285-3.827,P=0.004),lef t main with triple-vessel disease(HR 3.089,95％CI 1.310-7.283,P=0.010),uric acid levels(HR 1.003,95％CI 1.001-1.005,P=0.006)were independent risk factors of SCD.Conclusions The risk of sudden cardiac death after revascularization in coronary artery disease patients with heart failure were significantly higher in patients with tricuspid regurgitation,left main with triple-vessel disease and high uric acid levels.
