Exploratory echocardiographic strain parameters for the estimation of myocardial infarct size in ST-elevation myocardial infarction.

ABSTRACT:

Background

Outcome after ST-elevation myocardial infarction (STEMI) can be most reliably estimated by cardiac magnetic resonance (CMR) imaging. However, CMR is expensive, laborious, and has only limited availability. In comparison, transthoracic echocardiography (TTE) is widely available and cost-efficient.

Hypothesis

TTE strain parameters can be used as surrogate markers for CMR-measured parameters after STEMI.

Methods

TTE strain analysis was performed of patients included in a controlled, prospective STEMI trial (NCT01777750) 4 ± 2 days after the event. Longitudinal peak strain (LPS), post-systolic shortening, early systolic lengthening, early systolic lengthening time, and time to peak shortening were measured, and index parameters were computed.
