本文对20例冠心病患者进行选择性冠状动脉造影和左室电影法造影。结果显示左室射血分数的减少和左室舒张末压的升高与冠状动脉狭窄的程度相平行,表明冠状动脉狭窄程度是决定左室射血机能损害程度的重要因素。
In this paper, 20 cases of coronary heart disease patients underwent selective coronary angiography and left ventricular angiography. The results showed that decreased left ventricular ejection fraction and elevated left ventricular end diastolic pressure and coronary stenosis level parallel, indicating that the degree of coronary artery stenosis is an important factor in determining the extent of left ventricular ejection function damage.
