Cardiovascular magnetic resonance imaging assessment of outcomes in acute myocardial infarction

Table 3 Studies illustrating the prognostic importance of left ventricular strain in acute myocardial infarction

Ref.	Year	n	Modality	Main findings	Follow-up
Ersbøll et al[56]	2014	1048	TTE	(E-prime divided by peak early diastolic strain rate) strongest IP of MACE and death	29 mo
Ersbøll et al[57]	2013	849	TTE	GLS was IP of MACE	30 mo
Hung et al[58]	2010	610	TTE	GLS and strain-rate, and GCS and strain-rate IPs for MACE in model with WMS, LVEF	25 mo
Antoni et al[59]	2010	659	TTE	GLS (HR 1.2) was IP of mortality. LVEF, wall-motion score and Tissue Doppler mitral valve inflow not	21 mo

TTE: Transthoracic echocardiography; GLS: Global longitudinal strain; MACE: Major adverse cardiovascular events; IP: Independent predictor; HR: Hazard ratio; LVEF: Left ventricular ejection fraction.
