[Status of the coronary bed in post-infarction stenocardia].

Selective coronary angiography was performed in 80 patients with early postinfarction angina. All patients showed stenoses in at least one artery. Two vessels were affected in 37.5%, three vessels, in 51.3%, one vessel, in 11.3%. In 8.8% of cases, left coronary-arterial trunk was affected in addition to other arteries. Complete occlusion of one or several arteries was noted in 62.5%. There were marked collaterals in 20% of patients. The only difference between patients who showed relative resistance to medication and those whose condition could be stabilized was in the number of occluded vessels (69.2 and 35.1%, respectively). Coronary arterial lesions were operable in 68% of cases.
