Objective: discussion to the dynamic change of Serum cardiac troponin Ⅰ(cTn-Ⅰ) and the diagnostic value to the myocardial damage from patients with acute cerebral hemorrhage (ACH).Methods: study a group of 98 ACH patients; Serum cTn-I is measured in 98 patients with acute cerebral hemorrhage (ACH) at 24 h

72 h

7 d

14 d after the outbreak;Measure the nervous impairment when admission to hospital and divide it into mild

medium and heavy according to the dysfunction of nervous system;compare a group of 98 healthy physical testers and check their Serum cardiac troponin Ⅰ (cTn-Ⅰ) levels.Results: Serum cardiac troponin Ⅰ(cTn-Ⅰ) levels from 98 ACH patients at 24 h

72 h

7 d after the outbreak are distinctly higher than that from 98 ACH patients at 14 d and 98 healthy physical testers (P<0.01). The Serum cardiac troponin Ⅰ (cTn-Ⅰ) level from the group of 98 ACH patients at 14 d after the outbreak is meaningless in Statistics when compared (P>0.05);the higher the nervous impairment score in NIHSS is

the higher the cardiac troponin Ⅰ (cTn-Ⅰ) level is. The three cTn-I levels are distinctly meaningful when compared at 24 h

72 h

7 d after the outbreak(P<0.05).Conclusion: the early Serum cardiac troponin Ⅰ (cTn-Ⅰ) level of patients with acute cerebral hemorrhage (ACH) is obviously rising. So cTn-Ⅰ can be an index to the early investigation of myocardial damage from the patients with acute cerebral hemorrhage (ACH).
