“…'2- 14 We believe that the jeopardy score relates the extent of coronary artery disease to the degree of left ventricular damage more precisely than the standard designation of one, two, three-vessel disease. The jeopardy score has proved useful in predicting survival after aneurysmectomy,'5 and has previously been shown to be superior to the number of diseased vessels in predicting susceptibility to the cardiomyopathic syndrome resulting from coronary artery disease.5 Nevertheless, in the present study neither the jeopardy score nor the standard one, two, three-vessel disease classification predicted postoperative survival.…”

infarction less than one month before operation, and those undergoing resection of a left ventricular aneurysm or valve replacement were not included. Because of the small number of patients whose left ventricular ejection fraction was 030 or less, all of the nine consecutive patients who underwent grafting in 1976 and who had a left ventricular ejection fraction of 030 or less were also included in the study.Silhouettes of left ventricular end-systolic and end-diastolic right anterior oblique cine frames were drawn in all patients with abnormal wall motion, and the ejection fraction was calculated by the modified area-length method.4 The cineangiogram was not available for review in eight patients; in these cases, the left ventricular ejection fraction was estimated as greater than 030, 0-31 to 0 50, or greater than 0 50 from the narrative description in the ventriculographic report. Three patients did not undergo left ventriculography.The location and degree of coronary artery narrowing were determined from angiographic 549 on 10 May 2018 by guest. Protected by copyright.
