Etiology of troponin I elevation in patients with congestive heart failure and low clinical suspicion of myocardial infarction.

Background: Increased troponin I (TnI) has been detected in congestive heart failure (CHF) patients. We demonstrate that occurrence of LVH, and systolic and diastolic blood pressure values (SBP and DBP, respectively) correlate with increasing levels of serum TnI in a selected CHF population.

Methods: Our team reviewed the medical records of 40 consecutive patients admitted with CHF symptoms, low clinical suspicion of myocardial infarction (MI), and serum TnI measured upon admission.
