L. Lavecchia et al., DETECTABLE SERUM TROPONIN-I IN PATIENTS WITH HEART-FAILURE OF NONMYOCARDIAL ISCHEMIC ORIGIN, The American journal of cardiology, 80(1), 1997, pp. 88
Cardiac troponin I, a specific and sensitive marker of myocardial dama
ge, was detected in the blood of 6 of 26 patients studied in our Heart
Failure Clinic. In these patients functional class, ventricular funct
ion, and prognosis were significantly worse than in those without dete
ctable troponin I. This study suggests that troponin I may represent t
he biochemical marker of myocardial damage occurring in severe-heart f
ailure.
