Background: Primary intracerebral hemorrhage is one of the most common forms of stroke producing major disability. Cardiac troponin T is used as an indicator of severity in patients with primary intracerebral hemorrhage. The association between cardiac troponin T and severity of intracerebral hemorrhage has been infrequently studied. Aim: to identify the relationship between cardiac troponin T and severity of the clinical condition in patients with primary intracerebral hemorrhage measured by National Institutes of Health Stroke Scale (NIHSS). Methods: 60 patients were recruited from Neurology department Intensive care and Stroke units, Zagazig University Hospital with first time ever primary intracerebral hemorrhage during the period from October 2020 till July 2021. Cardiac troponin T was measured upon admission. Severity was assessed upon admission by NIHSS. Results: 35 (58.3%) patients had moderate score (5-15) upon admission compared to 15 (25%) patients with extremely severe condition (21-42), whereas 7 (11.7%) patients had severe condition and 3 patients (5%) had minor condition. Conclusions: Cardiac troponin T level is a valuable biomarker correlated with severity of intracerebral hemorrhage.
