Background: Fatty-acid binding protein-4 (FABP4) has been associated with the metabolic syndrome, diabetes mellitus, atherosclerosis, incident heart failure, and the prognosis of coronary heart disease (CHD). However, recent studies have not reported a significant correlation between FABP4 and cardiovascular (CV) mortality in high-risk patients or those with documented CHD. The present study aimed to evaluate the association between FABP4 and the prognosis in a cohort of patients with CHD who received coronary interventions. Methods: Serum FABP4 levels were measured in 973 patients after a successful intervention for CHD, who were then prospectively followed for 30 months. Result: During this period, 223 patients experienced composite CV outcomes (22.92%), defined as cardiovascular/cerebrovascular death, nonfatal myocardial infarction (MI), nonfatal stroke, hospitalization for refractory or unstable angina, hospitalization for heart failure, and peripheral artery occlusive disease. Kaplan–Meier curves showed a significant association between FABP4 levels at baseline (categorized in tertiles) and composite CV outcomes during follow-up (log-rank test, p
