Driving Pressure Optimization, RV-PA Coupling, and AKI in Mechanically Ventilated Critically Ill Patients

This study evaluates the effect of driving pressure optimization on right ventricular-pulmonary artery (RV-PA) coupling, assessed by TAPSE/PASP ratio, and its association with acute kidney injury (AKI) progression in mechanically ventilated critically ill patients.

Right Ventricular Function and Respiratory Acidosis After Cardiac Surgery

Right heart dysfunction remains a frequent cause of morbidity and mortality after cardiac surgery. Respiratory acidosis, particularly when accompanied by hypoxemia, plays a significant role in right heart failure, primarily by increasing right ventricular afterload through pulmonary vasoconstriction and elevated pulmonary arterial pressures. This phenomenon leads to increased right ventricular workload, causing dilation, decreased contractility, and ultimately right heart failure. The study aims to evaluate the effect of respiratory acidosis on right ventricular function after cardiac surgery.

Right Ventricular Response to Exercise Among Patients With Chronic Obstructive Pulmonary Disease

This study plans to learn more about heart function among individuals with chronic obstructive pulmonary disease (COPD). In particular, the investigators want to understand the different patterns of right ventricular response during rest and moderate- vs high-intensity exercise. By identifying patterns of right ventricular dysfunction, this study will help identify better treatments for patients with COPD in the future.
