Left ventricular hypertrophy and geometry in a population sample of elderly males
Abstract
Recent studies have shown that left ventricular geometric adaptation to hypertension is complex. The spectrum of geometric adaptations in a general population and its relationship to systolic and diastolic function has, however, not been investigated. This echocardiographic and Doppler study investigated the relationships between left ventricular geometric shape (normal, concentric remodelling, concentric hypertrophy and eccentric hypertrophy) and left ventricular systolic and diastolic function in a population sample of 584 males aged 70 in Uppsala, Sweden. The influences of hypertension, coronary heart disease and diabetes mellitus were also evaluated. Sixteen percent of the healthy population (n = 167) demonstrated the presence of left ventricular hypertrophy (mainly eccentric). Subjects with hypertension (n = 115) showed an increased left ventricular mass (eccentric left ventricular hypertrophy 31%, concentric left ventricular hypertrophy 15%), when compared with healthy subjects (P < 0.001). Subjects with coronary heart disease (n = 32) without hypertension also showed an increased left ventricular mass (most often eccentric) (P < 0.05). Using Doppler determinations of cardiac index, no differences were found in cardiac in...Continue Reading
