Adaptive capacity of the right ventricle: why does it fail?

Am J Physiol Heart Circ Physiol. 2015 Apr 15;308(8):H803-13. doi: 10.1152/ajpheart.00573.2014. Epub 2015 Feb 13.

Abstract

Only in recent years has the right ventricle (RV) function become appreciated to be equally important to the left ventricle (LV) function to maintain cardiac output. Right ventricular failure is, irrespectively of the etiology, associated with impaired exercise tolerance and poor survival. Since the anatomy and physiology of the RV is distinctly different than that of the LV, its adaptive mechanisms and the pathways involved are different as well. RV hypertrophy is an important mechanism of the RV to preserve cardiac output. This review summarizes the current knowledge on the right ventricle and its response to pathologic situations. We will focus on the adaptive capacity of the right ventricle and the molecular pathways involved, and we will discuss potential therapeutic interventions.

Keywords: heart failure; molecular; pulmonary hypertension; right ventricle; right ventricular failure.
