Lung water estimation using cardiac magnetic resonance imaging for predicting adverse cardiovascular outcomes in patients with heart failure

The present study sought to determine whether CMR-derived lung water density (LWD) measurement in pulmonary congestion has prognostic relevance in predicting adverse cardiovascular outcomes in patients with heart failure. The primary endpoint was all-cause mortality or HF-related hospitalization within 6 months from CMR. It concluded - 1. The mean lung water density was significantly higher in heart failure patients compared to healthy controls. 2. Patients with “wet lungs” i.e., lung water density >18.1%, had higher incidence of adverse cardiovascular outcomes compared to patients with “dry lungs”. 3. Lung water density was an independent predictor of adverse cardiovascular outcomes
