The clinical significance and clinical characteristics of patients with myocardial infarction involving the posterior wall of the left ventricle is not well-defined. The angiographic findings and their correlation with the eletrocardiographic (ECG) findings may be of high therapeutic importance. ⋯ The major artery causing involvement of the posterior wall is the right coronary artery. In patients with myocardial infarction involving the posterior wall, infarct size is similar to that of anterior wall myocardial infarction, and with similar complications rate. However, the incidence of significant mitral valve insufficiency and congestive heart failure is high in patients with posterior wall involvement. Posterior leads assessment should be conducted routinely in patients with suspected myocardial infarction.
