Background: primary intracerebral hemorrhage is a serious global issue producing marked disability affecting productivity on both national and international levels. Several studies have been directed to predicting functional outcome using variable biomarkers aiming to reduce undesirable outcome. Cardiac Troponin T has proved its role as a prognostic factor in several conditions but its efficacy in predicting outcome in ICH has been infrequently studied. Aim: to identify the relationship between cardiac troponin T and functional outcome in patients with primary intracerebral hemorrhage measured by modified Rankin scale (MRS). Methods: 60 patients were recruited having primary intracerebral hemorrhage admitted to neurology critical care unit at Zagazig University Hospital during the period between October 2020 and July 2021, studied by a prospective cohort study. Cardiac troponin T was measured upon admission. Functional outcome was assessed after 14 and 30 days by MRS. Results: 13 (21.7%) patients had favorable outcome after 14 days compared to 47 (78.3%) patients with unfavorable outcome. Whereas 27 (45%) patients had favorable outcome compared to 33 (55%) patients after 30 days by MRS. Conclusion: cardiac troponin T level is a valuable biomarker for predicting functional outcome in patients with primary intracerebral hemorrhage.
