Abstract

Background: The presence of coronary artery calcification (CAC) and its severity predict future cardiovascular events and is used for risk stratification. However, the association of CAC with heart failure (HF) in patients without a history of coronary artery disease (CAD) remains unclear. This study aimed to determine the correlations of CAC with N-terminal pro-B-type natriuretic peptide (NT-proBNP) and HF events in patients without a history of CAD or HF. Methods: From June 2010 to June 2013, a total of 487 patients without a history of CAD and HF were enrolled. All of the patients underwent plane multi-detector computed tomography. They were divided into four categories according to CAC scores: ≤10, 11-100, 101-400, and ≥401. Results: The proportion of patients with high NT-proBNP levels increased with CAC categories (p <0.0001). The CAC score was associated with NT-proBNP levels ≥400 pg/ml, with an odds ratio of 2.901 (95% confidence interval: 1.368-6.151, p = 0.0055) for CAC scores ≥401 compared with CAC scores of 0-10 after adjustment for confounding factors. During the follow-up period of 497 ± 315 days, nine patients were admitted for HF. Kaplan-Meier analysis showed that patients with CAC scores ≥401 had a lower rate of freedom from admission for HF with cumulative incidences of 0.4%, 1%, 2%, and 8% for CAC scores of 0-10, 11-100, 101-400, and ≥401, respectively (p <0.0001). Increasing CAC scores were associated with an increase in incidence of admission for HF, with a hazard ratio of 10.371 for CAC scores ≥401 (95% CI: 1.062-101.309, p = 0.0443) compared with CAC scores of 0-10 after adjustment for risk factors. Conclusion: Severe CAC is an independent determinant of high NT-proBNP levels and a predictor of admission for HF in a population without a history of CAD or HF.
