[Left ventricular diastolic function in subjects with arterial hypertension living in the Far North depending on the work schedule].
Left ventricular diastolic function (LVDF) was studied in subjects with arterial hypertension (AH) living in the Far North in relation to their working regime. A total of 95 patients with grade I-II AH were divided into two groups, one including 53 dayworkers the other comprising 42 patients working in shifts. The control group included 25 practically healthy subjects. All the patients were examined by Doppler echocardiography. Analysis of the results demonstrated that patients with AH working night shifts more frequently experienced LVDF disturbances than subjects of other groups. These disturbances included increased contribution of the left atrial systole to left ventricle filling. Patients with AH exhibited the well-apparent dependence of left ventricle diastolic filling on the degree of its hypertrophy. LVDF was related to the elevation of nocturnal arterial pressure due to a rise in systolic AP.
