심근의 일과성 허혈에 따른 좌심실 확장기 기능의 변화：색 M형 도플러 심초음파도의 유용성

Abstract

Left ventricular diastolic dysfunction may precede systolic dysfunction and play a major role in producing the signs and symptoms of congestive heart failure. Ischemic heart disease can cause impairment of left ventricular filling without any alteration in systolic function so it is very important to evaluate relationship of left ventricular diastolic dysfunction and ischemic heart disease. The purpose of this study is to investigate left ventricular diastolic dysfunction during transient myocardial ischemia caused by balloon occlusion.
