Pulmonary Hypertension in Disorders of the Left Heart Observations in a Catheterization Material

Abstract

Incidence, mortality implications, basic clinical correlations, and hemodynamic patterns at rest and on exercise of pulmonary hypertension in a material of left ventricular outflow obstruction and myocardial diseases are reported. The findings were essentially identical in both types of conditions; pulmonary hypertension occurred in those patients who were in clinically manifest left heart failure, was associated with a high mortality and, both at rest and on exercise, had similar hemodynamic characteristics, namely, a passive pressure transmission from an increased left ventricular diastolic pressure to the pulmonary vasculature.
