Key result
Prolongation of the corrected QT interval (QTc) upon admission was the only ECG predictor of death within 90 days among patients with hemorrhagic stroke (overall 90-day mortality 18%).
Why the study?
To analyze the relationship between ECG parameters in the acute period of hemorrhagic stroke and poor outcome within 90 days.
Does QTc prolongation on admission ECG predict 90-day mortality in patients with hemorrhagic stroke?
Observational (n=133)
Does QTc prolongation on admission ECG predict 90-day mortality in patients with hemorrhagic stroke?
Prolongation of the QTc interval on admission ECG is a predictor of 90-day mortality in patients with hemorrhagic stroke.
May inform early risk stratification in hemorrhagic stroke; hypothesis-generating and requires prospective validation before clinical adoption.
OBJECTIVE: To analyze the relationship between electrocardiogram (ECG) parameters in the acute period of hemorrhagic stroke and its poor outcome within 90 days. MATERIAL AND METHODS: ECG data of 133 patients with hemorrhagic stroke recorded upon admission to the primary vascular department were analyzed. RESULTS: Eighteen percent out of 133 patients died within 90 days. The only ECG-predictor of the poor outcome of hemorrhagic stroke was the prolongation of corrected QT interval (QTc). CONCLUSION: The length of QTc should be taken into account while assessing patients with hemorrhagic stroke. The patients with the abnormal QTc are at higher risk of the development of cardiac complications and death.

Khairullin et al. (2022) conducted an observational in Hemorrhagic stroke (n=133). Prolongation of corrected QT interval (QTc) vs. Normal QTc was evaluated on Poor outcome (death) within 90 days. Prolongation of the corrected QT interval (QTc) upon admission was the only ECG predictor of death within 90 days among patients with hemorrhagic stroke (overall 90-day mortality 18%).
