In order to assess the value of Doppler echocardiographic Tei index and B-Type natriuretic peptide (BNP) in evaluating the stenosis of coronary artery in patients with unstable angina and their relationship with myocardial ischemia. Ninety-two consecutive patients and 30 controls were included, all participants had underwent coronary angiography, according to the results, patients were divided into One-vessel disease group, Two-vessel disease group, Three-vessel disease group, Gensini Score were recorded. Echocardiography, neurohormonal analysis were performed. The results showed that Tei index and BNP were higher in patients with unstable coronary artery disease, they increased with the number of coronary artery stenosis, and were independent predictors of myocardial ischemia, they were useful in predicting high risk patients for invasive management.
