[Interrelations between blood pressure, age, body mass and echocardiographically determined left ventricular muscle mass of the heart in hypertensive and normotensive patients].

179 male hypertensives with predominantly mild hypertension were in comparison to 55 male normotensives investigated by means of a 2-D-regulated M-mode echocardiogram in order to prove the interrelations between blood pressure, age, body mass and left-ventricular muscle mass of the heart. The thicknesses of the wall of the left ventricle, the left-ventricular muscle mass and the left-ventricular muscle mass index were significantly larger in the hypertensives. Univariate calculations of correlation did not show any significant relations of the left-ventricular muscle mass to the height of the blood pressure but significantly positive relations with a small measure of distinctness to the body mass in the hypertensives and normotensives and to the age in the hypertensives. Conclusions for the valuation of echocardiographic findings in left-ventricular hypertrophy were derived.
