BACKGROUND: We aimed to assess apelin-novel endogenous ligand for the angiotensin-like 1 receptor in patients with ST-elevation myocardial infarction (STEMI) and to compare its value with B-type natriuretic peptide (BNP). METHODS: In 78 consecutive patients with first STEMI treated with primary PCI, plasma apelin-36 (RIA) and BNP (MEIA) concentrations were measured twice: on admission and on the fifth day of hospitalization. Left ventricle ejection fraction (LVEF) was assessed on admission and composite endpoint (CEP)-after 1 year follow-up. RESULTS: During the 5-day interval median plasma BNP level significantly increased and median plasma apelin concentration significantly decreased. BNP, but not apelin, correlated with low LVEF (<50%). In ROC analysis only BNP measurements were diagnostic for low LVEF. In ANOVA test, in patients with CEP, a significant decrease in apelin (but not BNP) concentrations measured in 5-day interval was found. ROC analysis identified only second BNP measurement as significant to estimate adverse outcome 0.627 in the prediction of CEP (95% confidence interval=0.507-0.736). CONCLUSION: Following STEMI there is a decrease of plasma apelin-36 concentration and an increase of plasma BNP concentration. BNP is better, than apelin diagnostic value for the detection of impaired LVEF. Both BNP and apelin have prognostic value, although both needs further evaluation.
