John Greenwood, an expert in pulmonary hypertension and heart-lung interactions, explores the devastating impact of pulmonary hypertension on cardiac function. He discusses the clinical heart-lung interactions, identifies high-risk patients, and shares critical management strategies. The podcast covers the causes and exacerbation of acute pulmonary hypertension, the often-overlooked right ventricle, and the effects of mechanical ventilation. It also delves into the differences between the left and right ventricles, the impact on coronary blood flow, and the use of pulmonary artery catheters.
