Left atrial mechanical function in patients with essential hypertension

摘要: Objective - This study was carried out to assess the left atrial (LA) mechanical function in patients with essential hypertension two-dimensional echocardiography by means of volume measurements. Methods LA volumes were measured echocardiographically 36 untreated hypertensive and 20 age-sex-matched healthy controls according biplane area-length method. measurements done at time mitral valve opening (V max ), onset systole (p wave electrocardiography = V p ) closure min ). All indexed for body surface area, following emptying functions calculated: passive -V , fraction /V conduit ventricular stroke volume-(V active / total . Results 0.05) similar both groups. Conclusion The results present indicate that chronic is associated an increased volumes, a decrease function, increase systolic pump function. Increased represents compensatory mechanism hypertrophy.
