Myocardial mechanical function measured by cardiovascular magnetic resonance in patients with heart failure.

ABSTRACT:

Background

Strain analysis offers a valuable tool to assess myocardial mechanics, allowing for the detection of impairments in heart function. This study aims to evaluate the pattern of myocardial strain in patients with heart failure (HF).

Methods

In the present study, myocardial strain was measured by cardiac magnetic resonance imaging feature tracking in 35 control subjects without HF and 195 HF patients. The HF patients were further categorized as HF with preserved ejection fraction (HFpEF, n = 80), with mid-range ejection fraction (HFmrEF, n = 34), and with reduced ejection fraction (HFrEF, n = 81). Additionally, quantitative tissue evaluation parameters, including native T1 relaxation time and extracellular volume (ECV), were examined.
