The aim of the present study was to investigate the effects of atorvastatin against heart ischemia/reperfusion (I/R) injury and its potential underlying mechanism. Rats were allocated into the following groups: Sham, I/R, atorvastatin (10 mg/kg daily), fasudil (10 mg/kg
daily) and atorvastatin + fasudil in combination. Drugs were administered for 2 weeks prior to I/R injury. I/R was established by ligating the left anterior descending branch (LAD) for 30 min and releasing the ligature for 180 min. The I/R group was found to have increased
myocardial infarct size, cardiomyocyte apoptosis, levels of plasma interleukin (IL)6 and tumor necrosis factor (TNF)α, superoxide dismutase (SOD) activity, malondialdehyde (MDA) levels and Rhokinase activity compared with the other treatment groups (P<0.05). Moreover, pretreatment
with atorvastatin significantly attenuated Rhokinase activity, myocardial infarct size, cardiomyocyte apoptosis, levels of plasma IL6 and TNFα, SOD activity and MDA levels, and upregulated nitric oxide production. It was also indicated that the specific Rhokinase inhibitor, fasudil,
had the same effects as atorvastatin in I/R. Therefore, the present results suggested atorvastatin may lead to cardiovascular protection, which may be mediated by Rhokinase inhibition in heart I/R injury.
