[The role of serum troponin I and high sensitivity C-reactive protein concentrations in early diagnosis of acute coronary syndrome in patients admitted to Emergency Unit].

The aim of this study was to show clinical benefit of simultaneous determinations of troponin I (cTnI) and high sensitivity C-reactive protein (hsCRP) at early diagnosis in the group of patients with stenocardia admitted to the Emergency Unit of 5-th Military Hospital in Krakow. The study group consisted of 38 (51.3%) patients with acute myocardial infarction (AMI) and 36 (48.6%) with unstable angina pectoris. ROC function analysis for cTnI (cutoff value 0.69 ng/mL) and hsCRP (3.33 mg/L) indicated significant amelioration of diagnostic sensitivity into 84.9% at early diagnostics of AMI in group of patients with acute coronary syndrome (ACS). Moreover, studies of mutual relationship between elevated levels of hsCRP and cTnI concentrations have shown a remarkably positive correlation (r = 0.90; p < or = 0.01) in the group of patients with AMI.
