Insulin-like growth factor-binding protein 7 and risk of congestive heart failure hospitalization in patients with atrial fibrillation.

Abstract：

BACKGROUND:The occurrence of congestive heart failure (CHF) hospitalization among patients with atrial fibrillation (AF) is a poor prognostic marker. OBJECTIVE:The purpose of this study was to assess whether insulin-like growth factor-binding protein 7 (IGFBP-7), a marker of myocardial damage, identifies AF patients at high risk for this complication. METHODS:We analyzed 2 prospective multicenter observational cohort studies that included 3691 AF patients. Levels of IGFBP-7 and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured from frozen plasma samples at baseline. The primary endpoint was hospitalization for CHF. Multivariable adjusted Cox regression analyses were constructed. RESULTS:Mean patient age was 69 ± 12 years, 1028 (28%) were female, and 879 (24%) had a history of CHF. The incidence per 1000 patient-years across increasing IGFBP-7 quartiles was 7, 10, 32, and 85. The corresponding multivariable adjusted hazard ratios (aHRs) (95% confidence interval [CI]) were 1.0, 1.05 (0.63-1.77), 2.38 (1.50-3.79), and 4.37 (2.72-7.04) (P for trend <.001). In a subgroup of 2812 patients without pre-existing CHF at baseline, the corresponding aHRs were 1.0, 0.90 (0.47-1.72), 1.69 (0.94-3.04), and 3.48 (1.94-6.24) (P for trend <.001). Patients with IGFBP-7 and NT-proBNP levels above the biomarker-specific median had a higher risk of incident CHF hospitalization (aHR 5.20; 3.35-8.09) compared to those with only 1 elevated marker (elevated IGFBP-7 aHR 2.17; 1.30-3.60); elevated NT-proBNP aHR 1.97; 1.17-3.33); or no elevated marker (reference). CONCLUSION:Higher plasma levels of IGFBP-7 were strongly and independently associated with CHF hospitalization in AF patients. The prognostic information provided by IGFBP-7 was additive to that of NT-proBNP.
