Hypotensive and cardioprotective effects of amlodipine (normodipine) were evaluated in 65 patients (35 men and 30 women) with grade II essential arterial hypertension treated with regard for calcium-controlling parathyroid function. 24 hour Holter monitoring, Doppler-cardiography, and blood PTH measurement were performed before and 6 months after the onset of therapy. The patients were divided into 3 groups depending on PTH levels (0-25, 26-50, and over 51 pg/ml). Changes of structural and functional cardiac parameters and AD were most prominent in group 3 in the form of decreased left ventricular hypertrophy, improved ventricular diastolic function, and marked hypotensive effect. The group was significantly different from group 1 in terms of these characteristics. Univariate analysis revealed correlation of PTH levels with left ventricular mass, mean daily systolic and diastolic AD, and left ventricular diastolic function. It is concluded that evaluation of calcium-regulating parathyroid function is necessary for optimization of antihypertensive therapy with calcium antagonists. |
