Summary

The aim of this study is to utilize lung ultrasound to detect the development of extravascular lung water in patients undergoing clinically indicated invasive hemodynamic exercise stress testing for symptomatic shortness of breath. The study will correlate the lung ultrasound findings with cardiac hemodynamics and measurements of extravascular lung water in an effort to better understand the pathophysiology of exertional dyspnea.

DIAGNOSTIC_TEST

Lung ultrasound

Lung ultrasound will be performed at baseline (resting), prior to exercise with passive leg elevation, after 1.5 minutes of 20 Watts exercise, during each subsequent stage, at peak workload and at 1 minute recovery. Pulmonary thermodilution will be performed at rest, peak stress and at 1 minute recovery.
