Abstract

Objectives: This retrospective study observed the elderly patients (≥71 years old) undergoing lone

CABG by single surgical team and same leading surgeon during the period of September 1997 to September 2007. The aim of the study was to find out whether chronological age is an independent mortality and major morbidity predicator of CABG surgery in Thai population.

Materials and Methods: One hundred and forty cases were divided into 2 groups; group A (younger age group) from 60-70 years old (n = 91) and group B (elderly group) from 71-89 years old (n = 49). The comparison of data was done under several variables such as preoperative risk factors, operative and post operative outcomes.

Results: Higher incidence of female gender in elderly (B) group, higher coronary risk factors and more critical angiographic lesions in younger (A) group were noted. Atherosclerotic diseases (CVA, PVD, and hypertension) as comorbid factors observed preoperatively were surprisingly not significantly different between the 2 groups. Although the incidence of renal dysfunction (Cr≥22) was higher among elderly, it did not affect CABG outcome and cannot be used as a predictor for higher potential of post-operative dialysis. The universal acceptance of cardiogenic shock with preoperative IABP, emergency surgery, poor EF as potent in-hospital mortality predictors was positive in this study. Postoperative stroke rate was insignificantly different between the 2 groups. In-hospital mortality in elderly group was 1.5 times higher than the younger group but there was no statistical significance (p value).

Conclusions: CABG in the elderly carries certain surgical risks. However, chronological age, by itself, is not independent survival predictor. The inferior mid- and long-term survival in the elderly was merely due to biological nature of aging.
