Neuroanesthesia & neurocritical care
Myocardial dysfunction assessed by speckle-tracking in good-grade subarachnoid hemorrhage patients (WFNS 1–2): a prospective observational study
Authors' conclusion
Strain imaging showed a higher prevalence (60.6%) of left ventricular dysfunction during the acute phase of good-grade SAH (WFNS 1 or 2) than previously described.
Study context

Methodological detailsblinded off-line strain analysis, Transthoracic echocardiography on days 1, 3 and 7 after hemorrhage
- Blinded off-line strain analysis
- Transthoracic echocardiography on days 1, 3 and 7 after hemorrhage
