Abstract
The potential predictors of left ventricular mass in old age were studied in a random sample of people born in 1904, 1909, 1914 (n=501; and 1920-35 (n=76). Data on the left ventricle with mass calculation, quantitative data on value disorders and biochemical data were collected. Left ventricular mass (corrected for height) was positively related to male gender, age, body mass index and systolic blood pressure. It was also significantly higher in the presence of aortic valve calcification, a low velocity ratio (indicating aortic value obstruction), and aortic or mitral re gurgitation. In men, left ventricular mass was higher in the presence of coronary artery disease and inversely related to serum high density lipoprotein cholesterol. In multivariate analysis, independent predictors of left ventricular mass without sex interaction were age (standardized coefficient ß=0.23, P=0.000). male gender (ß=0.38, P=0.000), body mass index (ß=0.22, P=0.000), systolic blood pressure (ß=0.21, P=0.000), velocity ratio (ß=-0.11, P=0.010), detectable aortic regurgitation (ß=0.11, P=0.014) and moderate-to-severe mitral regurgitation (ß=0.21, P=0.014) and moderate-to-severe mitral regurgitation (ß=0.21, P=0.000). Thus, the increase in left ventricular mass with age can largely be related to discrete predictors. The impact of valve disorders is substantial.
