title: Serum levels of cardiac troponin I in patients with status epilepticus and healthy cardiovascular system.
abstract: OBJECTIVE
  Status epilepticus (SE) is accompanied by acute and intense activation of the sympathetic nervous system, which might result in myocyte damage. However, there is insufficient evidence to assess cardiac biomarkers in SE patients. As a highly specific and sensitive biomarker of acute myocardial infarction, serum concentration of cardiac troponin I (cTnI) has been assessed in this study in a sample of SE patients without evidence of previous cardiovascular diseases.
  
  
  METHODS
  In this analytical cross-sectional study, a total number of 30 patients with SE and no history of baseline cardiovascular disorders, aged between 12 and 60 years have been evaluated. Baseline, demographic characteristics and laboratory measurements including cTnI, creatine kinase (CPK) and CPK-MB were recorded for all of patients. cTnI was quantified using ELISA method with the precision of 0.01 ng/mL.
  
  
  RESULTS
  All cases had a cardiac troponin level <0.01 ng/mL except for one 60- year-old female with a history of seizure 3 years prior. The last seizure was 60 days prior and the patient had a reported cTnI level as 0.04 ng/mL, within normal limits. The mean serum levels of CPK and CK-MB were 202.20 (SD = 14.46) μg/l and 14.54 (SD = 1.49) ng/mL, respectively.
  
  
  CONCLUSIONS
  This investigation is one of the few to evaluate serum concentration of cTnI in generalized convulsive SE patients where no detectable elevation was observed in serum concentration of cTnI following SE episode. However, it is very important to take into account that all recruited SE patients included in this study had a healthy cardiovascular system.
