Angina following a first non-Q wave infarction relationship to coronary anatomy
Abstract:
In patients under 60 years who are hospital survivors of a first non-Q wave infarction, outcome is good and the incidence of angina is high at 60%. Post-infarction angina is related to pre-infarction angina and responds to medical treatment in over 80% of patients. Angina is related to the extent and distribution of coronary artery stenosis. Patients with severe obstruction of the left anterior descending coronary artery and those with a totally obstructed infarct-related artery and jeopardized collaterals have a very high incidence of post-infarction angina. Coronary arteriography early after may help determine the subsequent management in patients who survive non-Q wave infarction.
