Figure 2.

Cardiac hypertrophy and pulmonary edema 4 weeks after coronary occlusion or sham surgery. The ratio of heart weight (HW; in mg) to body weight (BW; in g) was determined in the four experimental groups (n = 5 per group) as a measure of cardiac hypertrophy (A). The ratio of lung weight (LW; in mg) to BW (in g) was determined in the four experimental groups (n = 5 per group) as a measure of pulmonary edema (B). ^*p < 0.05, MI + saline versus sham + saline; #p < 0.05, MI + NaHS versus sham + NaHS. NaHS, sodium hydrosulfide; MI, myocardial infarction; NS, not significant; wk, week.
