Prognostic significance of resting cardiac power to left ventricular mass and E/e' ratio in heart failure with preserved ejection fraction.

ABSTRACT:

Background

Cardiac power-to-left ventricular mass (power/mass) is an index reflecting the muscular hydraulic pump capability of the heart, and the E/e' ratio is a specific indicator for identifying increased left ventricular filling pressure. Limited data exist regarding the prognostic value of incorporating power/mass and E/e' ratio in heart failure with preserved ejection fraction (HFpEF).

Materials and methods

In total, 475 patients with HFpEF from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial with complete baseline echocardiography data were included in our analysis. Patients were categorized into four groups according to power/mass and E/e' ratio. The risk of outcomes was examined using Cox proportional hazards m
