Stepping through a new door in La Porte IN

In this issue of the Journal of Geriatric Cardiology,Yang et al.1 studied the effects of arotinolol, a beta-blocker (BB), on the right ventricular (RV) function. (1) In the past, most studies were focusing on the left ventricle (LV) because the RV was considered only a passive conduit. (2) This study follows a new path in searching for a comprehensive understanding of RV function with possible pro-active and aggressive interventions in RV dysfunction and failure.
