Myocardial perfusion scan

Myocardial perfusion scan is a nuclear medicine procedure that evaluates many heart conditions from Coronary artery disease (CAD) to hypertropic cardiomyopathy and myocardial wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (LVEF) of the heart. This scan is done in conjunction with a cardiac stress test.

Major indications for a myocardial perfusion test: Diagnosis of CAD and various cardiac abnormalities. Identifying location and degree of coronary artery disease (CAD) in patients with a history of CAD. Prognostication (risk stratification) and evaluation of patients that are at risk of having a myocardial or coronary incident. (ex: myocardial infarction, myocardial ischemia, coronary aneurysm, wall motion abnormalities) Post intervention revascularivation (coronary artery bypass graph, angioplasty) evaluation of heart.
