Significance of cardiac weight in patients having coronary artery bypass grafting for angina pectoris.
Cardiac weight at necropsy in 211 patients who had coronary artery bypass grafting (CABG) for angina pectoris, and its relation to early (less than 60 days) and late (greater than 60 days) death after CABG was sought. The 121 patients dying early had a lower mean heart weight than did the 90 patients dying late (444 +/- 94 vs 498 +/- 107 g; p less than 0.001). The mean heart weight of the 85 men dying early was less than that of the 75 men dying late (472 vs 506 g; p less than 0.05), and the mean heart weight of the 36 women dying early was less than that of the 15 women dying late (377 vs 459 g; p less than 0.005). Most patients with hearts of normal weight were in the early death group: of the 17 women with hearts of normal weight (less than or equal to 350 g), 16 (94%) died early (p less than 0.01), and of the 34 men with hearts of normal weight (less than or equal to 400 g), 21 (62%) died early (difference not significant). Conversely, most patients in the late death group had hearts of increased weight: of the 15 women dying late, 14 (93%) had hearts of increased weight, and of the 75 men dying late, 62 (83%) had hearts of increased weight.(ABSTRACT TRUNCATED AT 250 WORDS)
