0046: Interest in the evaluation of exercise capacity by exercise stress testing in coronary artery disease – example of a series of diabetic women
In exploratory research strategy of coronary disease ranked first exercise stress test (EST). Beyond its positive predictive value represented by the repolarization triggered by stress, it provides additional prognostic and diagnostic information which includes exercise capacity especially in women. For women who cannot pedal, treadmill test according to the Bruce protocol allows a more accurate assessment of exercise capacity (EC) than a simple examination noting the exercise duration and intensity of the activity expressed in METs. Under exploration by treadmill test according to the Bruce protocol, 342 women with type 2 diabetes, in search of silent myocardial ischemia, exercise capacity (p=0.01) and exercise duration (p=0.001) emerged as significant in univariate analysis comparing the results of coronary angiography. And multivariate analysis patients who do not exceed 6 METs have stenosis (23%), OR=5,23X10 8 ; RR [IC 95%, 9,15X10 7 – 2,99X10 8 ], at least coronary infiltration (37%)(OR=9,21X10 7 ; RR [IC95%, 1,61x10 7 – 5,27x10 8 ] arteries and this in agreement with literature data. The modern interpretation of EST should include in addition to ST-segment changes, EC who is an important independent predictor of cardiovascular mortality both in the asymptomatic patient with coronary, moreover, it allows the evaluation of the protective effect of regular physical activity, especially for diabetic women.
