고혈압환자에서의 좌심실 확장기 기능의 평가:Color M-mode 도플러와 도플러 심초음파도를 이용한 방법

Abstract

Background : Several recent studies have demonstrated that left ventricular diastolic dysfunction is major cause of congestive heart failure and may precede systolic dysfunction of without left ventricular hypertrophy in most patients with systemic arterial hypertension. Method : From October 1994 to August 1995. 53 patients(18 men and 35 women, mean age : 56.1±12.6years) with essential hypertension and 30 subjects age-matched normal controls(13 men and 17 women, mean age 55.9±12.3years) were included in this study. Results : Early propagation slope of LV inflow was significantly decreased in patients with hypertension compared with normal control group(57.43±17.15msecs vs 69.87±12.71msecs, p<0.05). Conclusion : Left ventricular diastolic dysfunction may precrede systolic or without left ventricular hypertrophy in patients with systemic arterial hypertension.
