[Sensitivity, specificity and predictive value of the treadmill stress test in comparison with coronary angiography...

Precondition to prevention and control of morbidity and mortality of myocardial ischemia--coronary disease, is its good diagnostic. Goal of this study is to asses diagnostic significance of positive trademill stress test in diagnosis of coronary disease.

we analyzed 120 patients with markedly positive classic trademill stress test using Bruce protocol in the year 2003. In all cases, positive stress test was followed by selective angiography, using standard technique with multiple sections. Blood vessel narrowing of more than 50% was chosen as the criteria for positive angiographie finding. With the help of coronary angiography, it was found that 62 (51.7%) of patients has stenosis of less than 50% or normal angiographic finding. 58 (48.3%) of patients had stenosis of more than 50%. Of that number, 24 (41.4%) had one-vessel coronary disease, 12 (20.7%) two-vessel coronary disease, and 10 (34.5%) three-vessel coronary disease. 2 patients (3.4%) had stenosis of the trunk of left coronary artery. Results of this study show that the sensitivity of trademill stress-test is less than optimal, and should be supplemented by other non-invasive techniques (such as myocardial perfusion scintigraphy, radionuclide ventriculography and stress echocardiography) in diagnostics of coronary disease.
