Moderate alcohol consumption protects against coronary heart disease by unclear mechanisms. We tested whether chronic ethanol preconditioning requires activation of mitochondrial KATPchannels. Rats were fed 18% (v/v) ethanol in drinking water for 10 months. Blood alcohol levels at sacrifice were 3 mmol/l (0.015 gram percent). Isolated crystalloid-perfused hearts were subjected to global ischemia and reperfusion on a modified Langendorff apparatus. Prior alcohol exposure doubled the recovery of LVDP during reperfusion (45±5%v 20±3% of baseline for controls, n=6, P<0.01) and blunted the rise in LVEDP (3.5±0.5 v 5.5±0.4 times baseline for controls, n=6, P<0.01). Ethanol feeding also reduced creatine kinase release during reperfusion. Inhibition of mitochondrial KATPchannels with 5-hydroxydecanoate had no effect on baseline LVDP, LVEDP, or coronary flow but abolished the beneficial effects of alcohol on LV contractile recovery and myocyte necrosis. We conclude that mitochondrial KATPchannel activity is required for chronic ethanol-induced protection.
