Remodelling and left ventricular diastolic function in relation to blood pressure variability in patients with arterial hypertension and coronary heart disease

Abstract

Sixty five patients (mean age 55.7 ± 8,7 years), including 51 patients with arterial hypertension (AH) (mean age 54,9 ± 8,6 years) and 14 patients with a combination of AG and coronary heart disease (CHD) with postinfarction cardiosclerosis (mean age 54,9 ± 8,6 years) were examined. According to the values of average daily blood pressure variability (HPV), the patients were divided into subgroups with normal (11 patients with AH and 3 patients with AH and CHD) and increased (39 patients with AH and 12 patients with AH and CUD) BPV. Patients with isolated AH were found to have developed concentric hypertrophy of the left ventricle (LV), and moderate LV diastolic dysfunction mainly with impaired relaxation and the patients with a combination of AH and CHD with postinfarction cardiosclerosis had more significant LV structural and geometric derangements with a tendency for the development of eccentric hypertrophy of the LV, as well as more marked diastolic dysfunction with a larger proportion of the pseudo-normal and restrictive types of LV diastolic function. Patients with increased average daily BPV were found to have more significant LV structural, geometrical, and diastolic impairments.
