The Diagnostic Value of Dubious Positive in Exercise Treadm Ill Test in Patients with Coronary Artery Disease

Objective To explore the diagnostic value of dubious positive of exercise treadm ill test(TET) in patients with uncertain coronary artery disease(CAD),and coronary angiography is necessary to diagnosis of CAD.Methods A total of 104 dubious positive of TET in patients with uncertain CAD were did coronary angiography.Results Dubious positive of TET was 70.2%(73/104) in diagnosis of CAD.coronary angiography confirmed CAD were 25.0%,77.8% and 88.6% respectively in no or one dangerous factor,two dangerous factors and three dangerous factors or above,,compared was significantly difference respectively(P0.05).Conclusion Dubious positive of TET was higher,simple and convenient,economical,non invaseive method,and important value for diagnosis of CAD.If patients have two dangerous factors or above,coronary angiography is necessary for dubious positive of TET,and will decide treatment in future.
