Apelin Is Essential for Heart Contractility: Apelin Knockout Mice Have Weak Hearts

Animal StudyModerate evidence
The takeaway

Apelin gene-deficient mice developed impaired cardiac contractility with aging and pressure overload, proving apelin is essential for normal heart function and a potential therapeutic target for heart failure.

Key finding

Apelin knockout mice showed impaired cardiac contractility that worsened with aging and pressure overload, definitively establishing apelin as an esse

What the researchers found

Apelin knockout mice showed impaired cardiac contractility that worsened with aging and pressure overload, definitively establishing apelin as an essential cardiac peptide and a therapeutic target for heart failure and age-related cardiac decline.
