Recent studies using rodent models of transverse aortic constriction (TAC)-induced heart failure [12], myocardial infarction (MI) [13,14], and chemotherapy-induced cardiomyopathy [9] showed that the enhanced TRPV2 expression was associated with cardiac dysfunction and that TRPV2 plays an important role in general heart failure and cardiomyopathy [15]. The gene discussed is TRPV2; the disease is cardiomyopathy.
