Isoproterenol-induced Heart Failure Model
Isoproterenol, a nonselective beta-adrenergic agonist, cause cardiac injury and is commonly used in the study of heart disease. These models are classified into acute and chronic heart failure depending on the dose and duration of isoproterenol administration. Isoproterenol induced acute heart failure is a model characterized by acute apical segment ventricular dysfunction, simulating stress-induced cardiomyopathy (SIC) in human. Besides, the chronic model mimics advanced heart failure in humans. These models provides tools to study structural and functional adaptation of myocardium during the progression of heart failure.
Creative Bioarray specializes in providing customized pharmacodynamic research services to help customers assess the efficacy of drug candidates and study the associated pathological mechanisms through isoproterenol-induced heart failure model.
