The additive role of echocardiography in the screening for sudden death.

ABSTRACT: BACKGROUND:A clinically based sudden cardiac death (SCD) risk score has predictive value. Echocardiographic parameters predict SCD. Our aim was to evaluate the effect of adding echocardiographic parameters to the clinical SCD risk score for the prediction of all-cause mortality. METHODS:We conducted a retrospective cohort of screening echocardiograms performed on primary care patients. We calculated the SCD risk score and added the left ventricular (LV) mass index, LV hypertrophy, diastolic dysfunction, and LV ejection fraction (EF). We calculated the c-statistic, net reclassification index (NRI), and Hosmer-Lemeshow chi-square for the SCD score alone or combined with each echocardiographic parameter in predicting all-cause mortality. RESULTS:We included 6447 primary care patients who unde
