Why the study?
Do features of standard treadmill exercise testing predict transient myocardial ischemia during normal daily activities in patients with coronary artery disease?
Do features of standard treadmill exercise testing predict transient myocardial ischemia during normal daily activities in patients with coronary artery disease?
Patients with coronary artery disease and negative exercise electrocardiograms are highly unlikely to experience active ischemia during normal daily life, whereas early or prolonged ST changes during exercise strongly predict out-of-hospital ischemia.
No takes yet. Share an insight, caveat, or question.
Negative exercise ECGs may identify CAD patients unlikely to have daily ischemia; leaves open prospective validation for ambulatory risk stratification.
Campbell et al. (1986) studied this question.
