This study presents Kaplan-Meier curves illustrating cumulative rates of the combined endpoint, death/Myocardial Infarction (MI), based on cardiac troponin levels, cTnI and hs-cTnT, over a median follow-up period of 271 days. The analysis reveals significant survival probabilities associated with different thresholds of these biomarkers, indicating their diagnostic and prognostic importance in patients with acute coronary syndrome. The results show a strong correlation between elevated cTn levels and increased risk of adverse events, emphasizing the value of high-sensitivity assays in clinical practice.
