内容記述 |
The accumulation of intermediates subsequent to impaired β-oxidation of free fatty acid (FFA) has been suggested as a cause of cellular damage in ischemic myocardium. ^<1-2> We investigated the effects of propranolol and diltiazem on carnitine metabolism in ischemic myocardium. Propranolol (0.2 mg/kg/min, i.v.) and diltiazem (0.1 mg/kg/min, i.v.) were administered for 5 min, the administration started 10 min before coronary occlusion. ECGs were continuously recorded throughout the experiment. Myocardial samples were prepared from both the non-ischemic and ischemic areas 40 min after coronary ligation. Adenosine triphosphate (ATP), free carnitine, long chain acyl carnitine and long chain acyl CoA were assayed. Propranolol reduced the decrease of ATP and the accumulation of long chain acyl CoA, induced by myocardial ischemia. Diltiazem reduced the decrease of ATP and free carnitine, and the accumulation of long chain acyl carnitine in the ischemic area. Propranolol and diltiazem significantly reduced the grade of ventricular arrhythmia. These results suggest that the protective mechanisms of propranolol and diltiazem on myocardium are based, at least in part, on their beneficial effects upon myocardial carnitine metabolism |
