Impaired diastolic filling and adverse event risks in patients with ST-segment-elevation myocardial infarction: insights from four-dimensional flow magnetic resonance imaging.

ABSTRACT:

Background

Intra-cavity flow disorders have association with adverse cardiovascular events in patients with ST-segment elevation myocardial infarction (STEMI). This study aims to explore the characteristics of four-dimensional flow (4D-Flow) and its relationship with the adverse event risk scores in patients with STEMI.

Methods

Forty patients with STEMI (38 males, mean age 54.35 years) and 20 healthy controls (18 males, mean age 50.40 years) were prospectively enrolled for cardiac magnetic resonance (CMR) imaging. The 4D-Flow data analysis was performed using the MASS post-processing software. Left ventricular (LV) flow kinetic energy (KE) parameters included LV KE, in-plane KE, systolic KE, diastolic KE, E-wave KE, A-wave KE, E wave/A wave ratio (E/A ratio), and time differ
