To determine whether statin therapy protects diabetic heart tissue against ischemia-reperfusion injury through enhanced nitric oxide bioavailability independent of cholesterol reduction.
Diabetic (db/db) mice and nondiabetic controls received daily injections of simvastatin (0.5 mg/kg) or vehicle for 5 days.
Mice were subjected to 30 minutes of myocardial ischemia followed by 2 hours of reperfusion to assess tissue necrosis, leukocyte-endothelial interactions, and inflammatory responses.
Simvastatin significantly reduced myocardial necrosis from 62.6 ± 3.3% in vehicle-treated diabetic mice (n=12) to 37.0 ± 6.4% in simvastatin-treated diabetic mice (n=11, P < 0.02).
Cardiac eNOS mRNA expression increased by 97 ± 31% (n=7 per group, P < 0.05) and vascular nitric oxide production increased from 8.9 ± 1.5 to 16.0 ± 1.6 nmol/g (P < 0.05) without altering serum cholesterol.
Myocardial neutrophil infiltration decreased by 62% (P < 0.01) alongside attenuated leukocyte-endothelial interactions.
