chau-chung Wu 13,14,16* & Jaw-Wen chen 6,7,16* this study aimed to investigate the prognostic value of high-sensitivity creatine kinase-myocardial band or fraction (hsCK-MB) in comparison with other well-established biomarkers including heart type-fatty acid binding protein (H-FABP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with stable coronary heart disease (SCHD). A total of 1,785 patients were enrolled and followed for 36 months. The primary outcome was all-cause mortality. The secondary outcomes included cardiovascular (CV) death, acute myocardial infarction (AMI), angina-related hospitalizations, and hospitalizations for heart failure. The all-cause mortality rate was significantly higher in the high hsCK-MB group compared to the low hsCK-MB group (4.64% vs. 1.88%, p = 0.0026). After adjusting for baseline covariates, there were no significant differences for the secondary outcomes. H-FABP (≥4.226 ng/mL) was the best predictor for all-cause mortality (HR = 2.68, 95% CI = 1.28-5.62, p = 0.009) and cV death (HR = 6.84, 95% CI = 1.89-22.14, p = 0.003). The high NT-proBNP group had a higher AMIrelated hospitalization rate (HR = 1.91, 95% CI = 1.00-3.65, p = 0.05). Neither the addition of hsCK-MB to any other markers nor combinations of the three markers improved the prognostic significance of CV outcomes. In conclusion, hsCK-MB was an independent predictor for all-cause mortality but not CV outcomes in patients with SCHD. Combination of hsCK-MB, H-FABP and NT-proBNP failed to improve the prognostic power for all-cause mortality or CV outcomes. In 2018, the World Health Organization reported that 17.9 million people die each year, an estimated 31% of all deaths worldwide, from cardiovascular diseases including coronary artery disease, cerebrovascular disease, rheumatic heart disease and other conditions. Furthermore, 85% of all cardiovascular deaths are due to heart attack and stroke, and 60% of cardiovascular deaths occur in low-income and middle-income countries.
