The purpose of this study is to identify predictors of cardiac arterial stenosis severity. The subjects of the study were patients who underwent cardiovascular angiography. The predicted index was evaluated by the ankle brachial index, the left ventricular ejection fraction and the aortic valve velocity max of echocardiography. The severity of cardiac arterial stenosis increased in the elderly in their 70s and 80s. In cross-analysis of stenosis, the ankle brachial index was associated three times higher than the left ventricular ejection fraction and the aortic valve velocity max. Even in the correlation analysis, the ankle brachial index showed a high correlation as a predictor. Regression analysis showed that if the ankle brachial index was lower than 0.9, the probability of stenosis increased 6.1 times compared to the normal study subjects. and measurement of left ventricular ejection fraction revealed that subjects with low left ventricular ejection fraction were 3.3 times more likely to develop 3VD. Therefore, the predictor of cardiac artery stenosis was identified by the ankle brachial index and left ventricular ejection fraction.
