Exercise Thallium Tomography Predicts Future ,

In patients with clinically apparent CHD, a positive exercise ECG and/or thallium scintigram is associated with an increased likelihood of subsequent coronary events, but in most asymptomatic populations, noninvasive exercise testing results in a low predictive value due to a low prevalence of CHD 9 10 11 We hypothesized that the predictive value of stress testing and thallium scintigraphy ....
