TL;DR: Submaximal exercise 200T1 scintigraphy can distinguish high- and low-risk groups after uncomplicated acute myocardial infarction before hospital discharge and 201T1 defects in more than one discrete vascular region, presence of delayed redistribution, or increased lung thallium uptake are more sensitive predictors of subsequent cardiac events than ST segment depression, angina, or extent of angiographic disease.

TL;DR: It is concluded that diltiazem was effective in preventing early reinfarction and severe angina after non-Q-wave infarction and that it was also safe and generally well tolerated.

TL;DR: Among patients presenting with acute ischemic chest pain without persistent ST-segment elevation, blacks appeared to have less severe coronary disease, received revascularization less frequently, and had less recurrent ischemia compared with nonblacks, which suggests that more aggressive strategies should be directed to those patients with the greatest likelihood of adverse outcomes.

TL;DR: The admission ECG is very useful in risk stratifying patients with non-Q wave MI, whereas T wave inversion does not add to the clinical history in predicting outcome.

TL;DR: The preoperative distinction between viable and nonviable myocardium can be reasonably established by quantitating the amount of persistent reduction in thallium uptake and correlating this with preoperative wall motion.
