Regression of coronary artery obstructions demonstrated by coronary arteriography
Abstract
To determine the incidence and clinical features of regression of coronary artery obstructions we reviewed the angiograms of 93 nonoperated and 201 operated patients who had repeated coronary arteriographic studies. Regression of obstructions was found in 4 nonoperated cases (4.3%), all involving the left anterior descending artery. This was associated with improvement of the patient's clinical condition in only 1 case. No regressions were found in the surgical cases. Our data demonstrate that regression of coronary artery obstructions is rare and unrelated to clinical parameters.
