Abstract

To the Editor: Askenazi et al. (Dec. 24, 1981 issue)1 reported that an echocardiographically derived index (Q-MVC/AVC-E) and regression equation (36.6 (ratio) - 2.0) could accurately estimate mean pulmonary artery capillary pressure when applied to a group of stable patients undergoing cardiac catheterization. Subsequently, two letters published in the Journal2 , 3 raised conceptual questions about the application of this approach but presented no direct data further supporting or questioning the Askenazi formula. We evaluated the validity of the ratio in patients in the coronary-care unit who required a Swan–Ganz catheter, to study whether the ratio could predict wedge pressures and lead. . .
