Angiotensin converting enzyme 2 gene expression increased compensatory for left ventricular remodeling in patients with end-stage heart failure

Abstract It has been reported that angiotensin converting enzyme (ACE) 2, a homologue of ACE, has direct effects on cardiac function. However, the role of ACE2 in the development of human heart failure is not fully understood. We evaluated the expression of the ACE2 gene by means of real-time RT-PCR in myocardium from 14 patients with end-stage heart failure. The amount of ACE2 mRNA positively correlated with left ventricular (LV) end-diastolic diameter ( r 2 =0.56, p
