Right Ventricular-Pulmonary Artery Uncoupling and Strain in Acute Heart Failure.

ABSTRACT:

Background

Assessment of right ventricular-pulmonary artery coupling plays a crucial role in risk stratification, monitoring efficacy, and predicting outcomes in chronic heart failure patients. However, data in acute heart failure (AHF) are still lacking.

Methods and results

This multicenter observational study includes 425 patients with AHF: 248 with reduced left ventricular ejection fraction (<50%) and 177 with preserved left ventricular ejection fraction (≥50%). Pulmonary artery systolic pressure (PASP), tricuspid annular plane systolic excursion (TAPSE), longitudinal 2-dimensional strain of right ventricular (RV) free wall, and the RV end-diastolic diameter were measured by echocardiography. TAPSE/PASP and longitudinal 2-dimensional strain of RV free wall/PASP ratios wer
