Key result
Left ventricular global longitudinal strain evaluated by speckle tracking echocardiography improved significantly from -16.41% at admission to -18.76% on day 10 (p=0.003) in acute ischemic stroke.
Why the study?
Does myocardial function measured by speckle tracking echocardiography improve alongside neurological recovery in the early stage of acute ischemic stroke?

Does myocardial function measured by speckle tracking echocardiography improve alongside neurological recovery in the early stage of acute ischemic stroke?
In patients with acute ischemic stroke, left ventricular global longitudinal strain significantly improves by day 10, mirroring neurological recovery as measured by the NIHSS score.
May indicate transient myocardial involvement in acute ischemic stroke; leaves open prognostic utility of serial GLS beyond NIHSS.
PURPOSE: To evaluate the myocardial dysfunction in the early stage of nonhemorrhagic stroke and its association with the National Institutes of Health Stroke Scale (NIHSS) score, by two-dimensional speckle tracking echocardiography. METHODS: We included 29 patients with acute ischemic stroke, in whom NIHSS scores were calculated and stroke infarct volumes recorded. Within 48 hours of admission, cardiac evaluation with speckle tracking echocardiography was performed and left ventricular global longitudinal strain (GLS) and global longitudinal systolic strain rate were obtained. These measurements were repeated on the 10th day. RESULTS: NIHSS score improved, but infarct volume increased (p = 0.011 and 0.065, respectively) from admission to day 10. Ejection fraction was 53.2% and 55.8%, respectively, at admission and day 10 (p = 0.482), while GLS improved from -16.41% to -18.76% (p = 0.003). CONCLUSIONS: GLS and global longitudinal systolic strain rate showed significant improvement together with NIHSS score.

Ermiş et al. (2016) conducted an observational in Acute ischemic stroke (n=29). Two-dimensional speckle tracking echocardiography vs. Admission baseline was evaluated on Left ventricular global longitudinal strain (GLS) (p=0.003). Left ventricular global longitudinal strain evaluated by speckle tracking echocardiography improved significantly from -16.41% at admission to -18.76% on day 10 (p=0.003) in acute ischemic stroke.
