[Central hemodynamics and the functional state of the hypertrophied left ventricle in arterial hypertension].
Central hemodynamics and contractile function of the left ventricle were studied by catheterization and ventriculography in 43 patients with arterial hypertension. Significant decrease in the indices of left-ventricular contractility depending on the ECG findings and angiographic criteria of myocardial hypertrophy without dilatation of the cardiac cavities was revealed. At the same time, the indices of intramyocardial tension remained within normal limits or decreased slightly. Thus, left-ventricular hypertrophy in patients with arterial hypertension is of a compensatory character, develops according to a strictly concentric type, and is attended by diminished contractile function of the myocardium.
