: We evaluated the post-myocardial infarction (MI) therapeutic effects of Bendavia. Two hours after coronary artery ligation, rats were randomized to receive chronic Bendavia treatment (n=28) or water (n=26). Six weeks later, Bendavia significantly reduced scar circumference (39.7 ± 2.2 %) compared to water treatment (47.4 ± 0.03 %, p=0.024); and reduced left ventricular (LV) volume by 8.9% (p=0.0019). LV fractional shortening was significantly improved by Bendavia (28.8 ± 1.7 %) compared to water treatment (23.8 ± 1.8 %, p=0.047). LV ejection fraction was higher with Bendavia (55.3 ± 1.4%) than water treatment (49.3 ± 1.4%, p=0.005). Apoptosis, within the MI border zone, was significantly less in the Bendavia group (32 ± 3%, n=12) compared to the water group (41 ± 2%, n=12; p=0.029). Bendavia reversed mitochondrial function-related gene expression in the MI border, which was largely reduced in water-treated rats. Bendavia improved complex-I and -IV activity, and reduced reactive oxygen species production and cytosolic cytochrome c level in the peri-infarcted region. Bendavia improved post-MI cardiac function, prevented infarct expansion and adverse LV remodeling, and restored mitochondria-related gene expression, complex-I and -IV activity, and reduced reactive oxygen species and cardiomyocyte apoptosis in the noninfarcted MI border.
