Upregulated expression of cardiac ankyrin repeat protein in human failing hearts due to arrhythmogenic right ventricular cardiomyopathy

摘要

Aims Expression of cardiac ankyrin repeat protein (CARP) is augmented in heart failure due to dilated or ischaemic cardiomyopathy. It is unclear whether CARP is upregulated in heart failure due to arrhythmogenic right ventricular cardiomyopathy (ARVC). In the present study, we investigated the expression pattern of CARP and the correlation between CARP and the well-known heart failure marker pro-atrial natriuretic peptide (proANP) in ARVC failing hearts.
