Abstract:
After the performance of 100 coronary cineangiographies in 100 paitents who were adminitted to Soonchunhyang University Hospital under the diagnosis of ischemic heart disease from July 1986 to October 1987, we observed the coronary collateral circulation and measured the ejection fraction, circumferential fiber shortening, left ventricular end-diastolic pressure and pulmonary artery wedge pressure in 52 paitents who had 50% or more stenosis in one or more coroanry arteries. The results were as follow : 1) The collaterall circulation was observed in 16 patients(30.8%) of the 52 patients and it was developed mainly(87.5) in patients with 90% or more coronary artery stenosis. In patients with stenosis of less than 90%, however, collateral circulation was observed rarely(12.5%). 2) The left ventricular wall motion abnormality was severe in the group without collateral circulation. 3) The collteral circulation was most frequently developed in patients with severe right coronary artery stenosis and most of the routes were supplied from contralateral coronary arteries. 4) There was no significant difference in ejection fraction, circumferential fiber shortening, left ventricular end-diastoic pressure and pulmonary artery wedge pressure between the 2 groups with and without coronary artery collateral circulation.
