[Predictive factors of normal coronary angiography].
The aim of this study is to compare two groups of patients Group A consisted of 120 patients (70 men and 50 women) hospitalised for anginal symptoms, with either clinical or electrical positive exercise test and/or ischemic events on a 24 H electrocardiography and having angiographically normal coronaries Group B consisted of 120 patients (102 men and 18 women) hospitalised for an acute coronary syndrome with pathological coronaries. The analysis of the 2 groups showed that in the group A the average age was lesser (56 years vs 60 years), women's percentage was higher (41% vs 15%) and cardiovascular risk factors were less frequent. Data from non invasive tests was significantly different in the 2 groups: the exercise test showed both clinical and electrical ischemic events in 35% of the patients in group A versus 75% in group B (p < 0.01) and the 24 h electocardiography showed ST depression in 9% of patients in group A versus 25% in group B (p < 0.01%). The coronary angiography is an invasive and an expensive procedure. The results of our study allow us to modulate its indications, especially in young women patients, with few or no cardivascular risk factors and with only electrical positive exercise test.
