Left Ventricular Pressure Ratio Predicts In-Hospital Outcomes in Hospitalized Heart Failure With Reduced Ejection Fraction.

Background null Given the risk of hemodynamic compromise in heart failure with reduced ejection fraction (HFrEF) patients undergoing left heart catheterization (LHC), there is a need for a simple parameter that can predict clinical outcomes. We hypothesize that left ventricular pressure ratio (LVPR), calculated as left ventricle systolic/left ventricle end-diastolic pressure, is a strong predictor of hemodynamic collapse in these patients. null...
