title: [Effect of clofibrate on myocardial triglyceride accumulation in female obese Zucker rats].
abstract: OBJECTIVE
  To determine the effect of clofibrate on myocardial triglyceride accumulation in female obese Zucker rats and its role in lipotoxic heart disease.
  
  
  METHODS
  Twenty four female Zucker rats were divided into four groups: lean rats+vehicle, lean rats+clofibrate, obese rats + vehicle, obese rats+clofibrate. Daily intraperitoneal injection of clofibrate (300 mg/kg) or vehicle (olive oil, 1 mL/kg) was given to the rats for two weeks. Plasma glucose, insulin, free fatty acids, triglycerdies, cholesterol, and cardiac triglycerdies and fatty acids were measured.
  
  
  RESULTS
  Clofibrate normalized plasma free fatty acid and cholesterol and reduced plasma triglyceride and insulin in obese rats. However, clofibrate led to accumulation of heart TG and increased myocardial long-chain unsaturated and monounsaturated fatty acids in obese rats.
  
  
  CONCLUSIONS
  Clofibrate aggravates myocardial triglyceride accumulation in female obese Zucker rats. Further studies are needed for the use of clofibrate in treating cardiac lipid accumulation.
