Efficacy of coronary artery bypass grafting in elderly patients with coronary artery disease

Coronary Artery Bypass Grafting in the Elderly - A Review of Studies on Patients Older than 64, 69 or 74 Years

“…Previous myocardial infarction (MI) was diag nosed on the basis of history [ l-4] or the presence of Q waves or either [2,5,6]. Left ventricular (LV) function was abnormal in 6 studies [4,[7][8][9][10][11] on ventriculographic assessment and was considered poor if LV ejection fraction was less than 50 [ I ].…”

“…Left ventricular (LV) function was abnormal in 6 studies [4,[7][8][9][10][11] on ventriculographic assessment and was considered poor if LV ejection fraction was less than 50 [ I ]. 45 [2], 40 [5], 35 [ 12] or 30% [ 13], LV enddiastolic pressure was consid ered raised if it was more than 15 [ 1. 9].…”

“…8. 10, 16] the criteria to diagnose perioperative MI was not defined, and in three studies [2,7,14], the appearance o fa new Q wave was required. Definite perioperative Ml was consid ered to have occurred if there were new Q waves together with CPK-MB levels above 15 IU/1 [15] or above 25 pg/1 [ 17], Prolonged ventilatory assistance [5.…”

Cardiac surgery for patients aged 65 years and older: a long term survival analysis.

“…A multifactorial analysis (Cox proportional hazard model) with stratification by operation showed that the relative annual risk ofdeath associated with being over 70 at operation was 1-45, (95% CI 0-97 to [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], that for operation after 1980 was 0-79 (95% CI 0X52 to 1X21), and that for being female was 0-95 (95% CI 0-65 to When we compared the expected and actual survival rates in the study population, we found that the expected one year rate was 96-4% and the actual rate was 88 0%. For the five year rates the corresponding figures were 80-1% expected compared with 74-4% actual.…”
