Sudden Cardiac Death in Patients With Stable Coronary Artery Disease and Preserved Left Ventricular Systolic Function

Although sudden cardiac death (SCD) has been extensively studied in patients with coronary artery disease (CAD) and low ejection fraction, prediction of SCD among individuals with preserved left ventricular systolic function is less well understood. We randomized 8,290 patients with stable CAD with preserved left ventricular systolic function to trandolapril or placebo in a secondary coronary prevention trial, and we used Cox proportional hazards models to identify independent baseline predictors of SCD during 4.8 year follow-up (median). Using a risk scoring algorithm based on simple clinical characteristics, we were able to distinguish individuals at higher risk for SCD. Independent determinants of SCD included age (p 40% to 50%) (p
