Ischemia and Myocardial Infarction
The echocardiogram is a standard tool in the evaluation and treatment of patients with acute myocardial infarction (AMI). The role of echocardiography is to establish the diagnosis, location, and extent of myocardial infarction, to diagnose mechanical complications of infarction, and to provide prognostic information important for risk stratification and short- and long-term outcome. The use of echocardiography in ischemic heart disease is based upon the rapid change in wall motion of a segment after an interruption or critical decrease in its blood supply. Echocardiography is a valuable, noninvasive diagnostic tool that can provide information about systolic function and valvular abnormalities and can provide alternative explanations for the causes of chest pain, such as aortic dissection, aortic stenosis, cardiac tamponade, pericarditis, and hypertrophic cardiomyopathy.
