PURPOSE:: To improve risk stratification for development of ischaemic heart disease, several markers have been proposed. Both the presence of coronary artery calcification (CAC) and ECG pattern of left ventricular hypertrophy/strain have been shown to provide independent prognostic information. In this study, we investigated the association between established risk factors, ECG measurements and the presence of coronary artery calcification. METHOD:: A random sample of healthy men and women aged 50 or 60 years were invited to the screening study. Established risk factors were measured. A noncontrast computed tomographic (CT) scan was performed to assess the CAC score. ECG analysis included left ventricular hypertrophy (LVH) using the Sokolow-Lyon criteria and the Cornell voltage × QRS duration product, and strain pattern based on ST segment depression and T-wave abnormalities. The association between the presence of CAC, clinical variables and ECG findings was evaluated by means of multivariate logistic regression. RESULTS:: Of 1825 invited individuals, 1226 accepted the screening. The prevalence of hypertension was 50%. Hypertensive patients frequently had LVH and/or strain when compared with nonhypertensive individuals (21 vs. 14%, P
