Hypothesis
cTnT elevation in acute stroke patients is generally not caused by coincidental myocardial infarction.
Conclusion
The study aims to clarify the frequency and causes of troponin elevation in ischemic stroke patients to improve clinical management.
Supporting Evidence
- Elevated troponin levels are common in acute ischemic stroke patients.
- Troponin elevation is associated with poor outcomes and mortality.
- Coronary angiography will be used to investigate underlying causes of troponin elevation.
Takeaway
This study is trying to find out why some stroke patients have high levels of a heart protein called troponin, which might help doctors treat them better.
Methodology
A prospective observational trial screening acute ischemic stroke patients for troponin T levels and conducting coronary angiography if elevated.
Potential Biases
Potential bias due to the single-center design and exclusion of patients with renal insufficiency.
Limitations
The study has a small sample size and may not detect smaller differences in secondary endpoints.
Participant Demographics
Patients with acute ischemic stroke admitted within 72 hours after symptom onset.
