Relationship to Clinical Outcomes

La Vecchia et al. (15) investigated the clinical usefulness of cTnI as a diagnostic and prognostic marker in patients with severe heart failure. They enrolled 34 patients with NYHA functional class II-IV CHF and stratified them into two groups based on the presence or absence of detectable cTnI. The study showed that detectable levels of cTnI identified a high-risk subgroup of patients (n = 10; 29%) with increased short-term mortality (hazard ratio: 6.86; 95% confidence interval [CI]: 1.32-35.4). Furthermore, LVEF was significantly lower in patients with elevated cTnI compared with patients with undetect-
