[The function of the collateral bed in patients with ischemic heart disease and isolated occlusion of the anterior descending branch of the left coronary artery].
To study the collateral bed, 39 coronary heart disease patients with isolated occlusion of the anterior descending artery without a history of large-focal myocardial infarction were examined. All the patients were subjected to coronary angiography and left ventriculography. Based on an analysis of left ventricular myocardial contractility, the patients were distributed into 2 groups. The first group included 16 patients without disorders of local contractility of the left ventricular myocardium, the second one 23 patients with derangement of local contractility of the left ventricular myocardium. The conclusion is made that in patients suffering from stable angina pectoris with isolated occlusion of the anterior descending artery without a history of large-focal myocardial infarction, exclusively intersystemic collateralization of the vessel via the conal artery (or the conal branch of the right coronary artery) is most favourable from the standpoint of the maintenance of myocardial contractility.
