Minor Myocardial Damage is a Prevalent Condition in Patients With Acute Heart Failure Syndromes and Preserved Systolic Function With Long-Term Prognostic Implications. A Report From the CIAST-HF (Collaborative Italo-Argentinean Study on Cardiac Troponin T

Increased cTnT levels were detected in approximately 50% of patients with AHFS with preserved systolic function, and were found to correlate with clinical measures of disease severity. The presence of MMD was associated with a worse long-term outcome, lending support to cTnT-based risk stratification in the setting of AHFS.
