  1. There was a significantly higher ratio of Bax:Bcl-2 (mean ± SEM) in the myocardium in the depression, MI (myocardial infarction) and post-MI depression groups than in the sham group (a P < 0.01). Furthermore, in the post-MI depression and MI groups there was a significantly higher ratio of Bax:Bcl-2 than in the depression group(b P < 0.01), and in the post-MI group there was a significantly higher ratio of Bax:Bcl-2 than in the MI group (c P < 0.01).
