Left ventricular performance of angina pectoris were improved in surgical group 6 months after A-C bypass with the significance of p＜0.02-0.05. However, in the medical group, it showed unchanged or aggravated tendency during average 18 months. Similar results were obtained in the patients with left ventricular aneurysm and furthermore, agrravation of EF and Max dp/dt/p in some medically treated cases was observed.
Operative death by A-C bypass was seen in 4 cases (2.7%) and 5 years cumulative survival rate was 92.6% including late death cases died during average 30.1 months in the medical group and its 5 years survival rate was 77.3%.
For left ventricular aneurysm, no operative death was recognized and the 5 years cumulative survival rate was 95%. Whereas during average 32.7 months in the medical group, 8 cases died and 5 years cumulative survival rate was 78.6%.
Improvement of subjective symptoms after treatment for both ischemic heart diseases was also compicuous in the surgical group.
