- Abstract
Background: Our aim was to assess the association of left ventricular mass with mortality and nonfatal cardiovascular events. Methodology/Principal Findings: Left ventricular mass was measured by echocardiography in 40138 adult patients (mean age 61.1±16.4 years, 52.5% male). The primary endpoint was all-cause mortality. Secondary endpoints included nonfatal myocardial infarction and nonfatal stroke. During a mean follow-up period of 5.6±3.9 years, 9181 patients died, 901 patients had a nonfatal myocardial infarction, and 2139 patients had a nonfatal stroke. Cumulative 10-year mortality was 26.8%, 31.9%, 37.4% and 46.4% in patients with normal, mildly, moderately and severely increased left ventricular mass, respectively (p,0.001). Ten-year rates of nonfatal myocardial infarction and stroke ranged from 3.2% and 6.7% in patients with normal left ventricular mass to 5.3% and 12.7% in those with severe increase in left ventricular mass, respectively. After multivariate adjustment, left ventricular mass remained an independent predictor of all-cause mortality (hazard ratio [HR] per 100 g increase 1.21, 95% confidence interval [CI] 1.14-1-27, p,0.001 in women, and HR 1.09, 95% CI 1.04-1-13, p,0.001 in men), myocardial infarction (HR 1.60, 95% CI 1.31-1.94, p,0.001 in women and HR 1.15, 95% CI 1.02-1.29, p = 0.019 in men) and stroke (HR 1.26, 95% CI 1.13-1.40, p,0.001 in women and HR 1.19, 95% CI 1.09-1.30, p,0.001 in men). Conclusions/Significance: Left ventricular mass has a graded and independent association with all-cause mortality, myocardial infarction and stroke.
