title: [Left ventricular function and state of the coronary tree in patients with significant coronary lesions (author's transl)].
abstract: The prognosis of patients with ischemic cardiopathy is mainly based upon the number of affected vesssels, the state of the distal coronary tree, and the left ventricular function. Coronary arteriographies and ventriculographies corresponding to 274 consecutive patients (January, 1975-October, 1978) with significant coronary lesions are reviewed. A singles vessel obstruction was registered in 36.5 percent of the patients; obstruction of two vessels was present in 28.5 percent, and of three vessels in 29.9 percent. The common left trunk was obstructed in 5.1 percent of the cases. The anterior descending coronary artery was affected in 78 percent of the patients, and the left coronary artery, circumflex, first marginal branch, and first diagonal branch showed narrowing in 62, 34, 36, and 26 percent, respectively. The distal tree of the above mentioned arteries was appropriate for coronary bypass operations in 51, 49, 50, 38, and 10 percent of the arteries, respectively. On the basis of coronary angiographic and ventriculographic criteria 117 patients (43 percent) were not candidates to coronary bypass surgery. The ejection fraction was less than 0.40 in 22 percent of the cases, and below to 0.30 in 12 percent (34 patients). The outstanding finding in the present series was the impairment of the distal coronary tree due to advanced atherosclerosis.
