Abstract

OBJECTIVE:

To determine whether circulating level of catestatin (CST) could provide prognostic information independently of conventional risk markers for the development of in-hospital heart failure in patients with ST-segment elevation myocardial infarction (STEMI).

METHODS:

The data of 120 STEMI patients (mean age: 61 years, 73% male) were collected from the Second Hospital of Shanxi Medical University and Taiyuan Central Hospital between November 2010 and September 2011.The patients were categorized into 4 groups according to CST (ng/L) quartile: ≤ 74.72, 74.73-79.67, 79.68 - 84.21 and ≥ 84.22 ng/L. Clinical features, therapeutic approaches were compared among groups. The patients were also grouped according to Killip class: Killip level I (n = 68), Killip level II (n = 23), Killip level III (n = 18), Killip level IV (n = 11). CST, NE and NT-proBNP were compared among groups. The Spearma rank correlation and multivariate logistic regression analysis were applied to determine the association between risk factors and in-hospital heart failure. Receiver-operator characteristic (ROC) curve was performed to evaluate the power of CST and NT-proBNP on predicting in-hospital heart failure.

RESULTS:

Gender, hospital days, past history of smoking, hypertension, myocardial infarction, CK-MB peak level, TnI peak level, heart rate, blood pressure, blood glucose, blood lipid levels on admission and early reperfusion therapy were similar among groups. Patients with higher CST values were more likely to be older, to have lower body mass index, to have higher white blood cell count, CysC, hs-CRP, NE, NT-proBNP, past history of angina, diabetes mellitus, being diuretic users, and to have a lower ejection fraction (all P < 0.05). Higher CST levels were also associated with increased risk of heart failure (P < 0.05). In proportion with the deterioration of the cardiac function, CST, NE, NT-proBNP concentration gradually increased (all P < 0.05). Spearman rank correlation analysis showed that the CST was negatively correlated with LVEF (r(s) = -0.923, P < 0.001) and positively correlated with NT-proBNP (r(s) = 0.884, P < 0.001). After multivariate adjustment, CST remained to be an independent risk factor for the development of in-hospital heart failure (OR = 1.125, 95%CI: 1.056 - 1.198;P < 0.001). The area under the ROC curve of CST and NT-proBNP was 0.777 and 0.874. Using CST = 77.29 ng/L as a cut-off value, the sensitivity was 92.8% and specificity was 70.6% for predicting the development of in-hospital heart failure.

CONCLUSION:

The plasma CST level is an independent predictor for the development of in-hospital heart failure in patients with STEMI.
