Does elevated troponin I predict poor outcomes and in-hospital mortality in patients with acute ischemic stroke?
Elevated troponin I during acute ischemic stroke is a strong independent predictor of poor functional outcomes and in-hospital mortality.
Effect estimate: OR 28.451 (95% CI 2.785-290.63)
p-value: p=0.005
Background: Stroke is the second leading cause of death worldwide, comprising approximately 10% of all deaths. A substantial number of stroke patients have elevated cardiac troponin levels and are associated with poorer prognosis. Methods: This was a prospective observational study conducted for 1 year at Tribhuvan University Teaching Hospital, in which 101 acute ischemic stroke patients were enrolled. Data included vital signs, laboratory parameters, and clinical features evaluated at the time of admission. The National Institute of Health Stroke Scale (NIHSS) and modified Rankin scale (mRS) were used to assess stroke severity and outcomes. Results: Elevated troponin I (> 0.034 ng/mL) was observed in eight (7.9%) patients. Compared to patients with normal troponin I, patients with elevated troponin I were older(mean age 61vs 59.68 years), had higher blood glucose( 10.6 vs. 7.04 mmol/L), higher median white blood cells( 9.3 vs. 8.9 1,000/m3) and creatinine levels(119.5 μmol/L vs. 95.9 μmol/L), higher mean NIHSS scores on admission(16 vs. 8.6), and discharge(14.5 vs. 6.8), higher median mRS scores( 4.13 vs. 1.8) at discharge(p13(OR 15.902; 95%CI3.65-69.28,p=0.029 ng/mL (odds ratioOR:28.451; 95% CI2.785-290.6,p=0.005) were significant predictors of poor outcomes. Significant predictor of in hospital mortality only included troponin I level >0.04 ng/mL (0R 0.071; 95% CI 0.005-1.037, P=0.05). Conclusion: Troponin I provide better information than age and other laboratory parameters in the prediction of outcomes of stroke. Elevation of troponin I during acute stroke is a strong predictor of both poor outcomes and in-hospital mortality.
Thapa et al. (Wed,) conducted a observational in Acute ischemic stroke (n=101). Elevated Troponin I (>0.029 ng/mL) vs. Normal Troponin I was evaluated on Poor outcomes (mRS > 2 at discharge) (OR 28.451, 95% CI 2.785-290.63, p=0.005). Elevated troponin I (>0.029 ng/mL) during acute ischemic stroke was a strong independent predictor of poor functional outcomes at discharge (OR 28.451).
