Key result
In patients with STEMI treated with late PCI, global longitudinal strain independently predicted left ventricular remodeling (OR 0.39; 95% CI 0.26-0.57; P<0.01).

May support GLS for post-late PCI STEMI risk stratification; hypothesis-generating and requires prospective validation before practice change.

Global longitudinal strain measured by speckle tracking echocardiography is a strong predictor of left ventricular remodeling and adverse clinical events in STEMI patients undergoing late PCI.
Cong et al. (2014) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=127). Global longitudinal strain (GLS) measured by speckle tracking echocardiography was evaluated on Left ventricular remodeling (LVr) defined as >15% increase in LV end-systolic volume after 6 months (OR 0.39, 95% CI 0.26-0.57, p=< 0.01). In patients with STEMI treated with late PCI, global longitudinal strain independently predicted left ventricular remodeling (OR 0.39; 95% CI 0.26-0.57; P<0.01).
