Hypothermia as an adjunctive therapy to percutaneous intervention after ST-elevation myocardial infarction-Effects on regional myocardial contractility.

ABSTRACT:

Background

The effects of endovascular therapeutic hypothermia (ETH) in ST-elevation myocardial infarction (STEMI) regional contractility are unknown, and its impact on segmental contractility has still not been evaluated. We sought to evaluate segmental myocardial strain after ETH adjuvant to percutaneous coronary intervention (PCI) in STEMI.

Methods

We included patients who underwent 1.5T cardiovascular magnetic resonance exams 5 and 30 days after acute anterior or inferior STEMI in a previous randomized trial. Left ventricle (LV) strain was evaluated on infarcted, adjacent, and remote myocardium. Segmental circumferential (CS) and radial strains (RS) were measured using feature-tracking imaging. Repeated measures of analysis of variance were used for comparisons within ti
