title: [Five year dynamics of the characteristics of left ventricular diastolic function in patients with arterial hypertension in the Far North].
abstract: The work was aimed to study five-year dynamics of characteristics of left ventricular diastolic function in patients with arterial hypertension (AH) under conditions of continuous shiftwork in the Far North. The first stage of the study (2003-2005) involved 95 patients including 53 day-shift ones and 42 subjects working alternately on day and night shifts. At the second stage (2007-2011), prospective observation of both groups using Doppler echocardiography was organized. The patients were divided into 2 subgroups (with treated and untreated AH). It was shown that AH patients in the Far North frequently suffer disturbances of left ventricular diastolic function manifest as increased contribution of left atrial systole to left ventricular filling. This phenomenon was more pronounced in nightshift workers.
