title: [Calcium metabolism in various forms of hypertrophy of the "hypertensive" heart].
abstract: To study the changes occurred in integral calcium metabolic parameters in evolving "hypertensive" heart, a total of 100 patients with Stage I-II (WHO Classification) were examined. Myocardial structure and function were echocardiographically examined. Plasma concentrations of ionized calcium were measured by direct potentiometry. Plasma levels of calcitonin and parathyroid hormone were measured by radioimmunoassay. As the "hypertensive" heart progressed, the ionization of serum calcium was found to enhance along with an increase in calcitoninemia. In early formation of the "hypertensive" heart, parathyroid hormone remained unchanged, but became elevated only in severe left ventricular hypertrophy. The findings may explain the features of the clinical aspects of variant left ventricular hypertrophies in the "hypertensive" heart.
