摘要

The hemodynamic results of cardiomyoplasty, a promising form of surgical treatment for end-stage heart failure, do not support the subjective improvements seen clinically. We hypothesized that this disparity might be due to ischemia-reperfusion injury to the latissimus dorsi muscle (LDM) after mobilization. Having tested autologous biological glue (ABG) as a protective layer around traumatized muscle, as a means for facilitating revascularization, and as a drug depot to reduce local ischemia-reperfusion lesions, we wanted to determine if this protective and revascularization effect could be enhanced by adding aprotinin, a natural inhibitor of serine proteinases with the potential for preventing proteolytic degradation. To test for muscle damage and angiogenesis, we created pockets out of ischemic and nonischemic LDM. The control group had pockets without additives; the second group had pockets with ABG only; and the third had pockets with ABG and aprotinin. Light microscopy revealed that pockets treated with ABG, either alone or with aprotinin, had less leukocyte margination, fibrosis, calcified necrosis, and fibrous degeneration than in controls. In control pockets, after 56 days, capillaries occupied 4.1 ± 0.3% of the area in nonischemic LDM and 3.6 ± 0.7% in ischemic LDM (p > 0.05). In pockets treated with ABG only, capillaries occupied 5.5 ± 0.2% (p
