Abstract:
Objective Through observing the change of serum cTnT level and other biochemical markers such as T3 and TNF-αin acute ischemic stroke patients , to investigate the correlation between the indictors change and short-term prognosis and stroke severity .Methods This study observed 68 patients (male 35 cases ,mean age 68 ±11.4 years; female 33 cases, mean age 69 ±10.3 years).All cases were collected fasting blood sample to test cTnT ,T3 and TNF-α.Death and other unexpected events were recorded in the form of telephone follow-up within one month in survival patients during and discharge from hospital.Results According to cTnT detection level ,all cases were divided into two groups , normal group (54 cases,79.4%) and positive group(14 cases,20.6%).There was statistical significance between posi-tive cTnT and NIHSS score neurological deficits ( p <0.01).cTnT was negratively correlated with T3( r =-0.324 , P <0.05 ) ,but positively with TNF-α( r =0.67 , P =0.017 ) .All patients were followed up for one month.14.7%patients died including 11.7%during hospital and 3% after discharge.After age, NIHSS adjustment cTnT remains an independent risk factor for death ( RR=2.34 ,95%CI=1.22-5.02 , P<0.01 ) .Conclusion After acute ischemic stroke , cTnT is correlated with dropping T 3 level and in-creasing TNF-αlevel, suggesting that both stress and inflammatory response may be involved in heart dam-age.Abnormal elevation of cTnT influenced short-term prognosis of acute ischemic stroke , which can be used as short-term indicators of poor prognosis in the clinical observations .
