Insights
Heart-type fatty acid binding protein (H-FABP) shows prognostic value in chronic kidney disease (CKD) patients. H-FABP is linked to non-cardiovascular death and major adverse cardiovascular events, independent of high-sensitivity troponin T (hs-TNT).
Area of Science:
- Cardiology
- Nephrology
- Biomarker Research
Background:
- Heart-type fatty acid binding protein (H-FABP) offers prognostic insights in coronary artery disease.
- Its independent association with cardiovascular outcomes in chronic kidney disease (CKD) remains to be fully elucidated.
Purpose of the Study:
- To investigate the independent associations of H-FABP with cardiovascular outcomes in patients with CKD.
- To assess H-FABP's prognostic value beyond established risk factors and hs-TNT.
Main Methods:
- A prospective cohort study of 4,951 German Chronic Kidney Disease (GCKD) study participants.
- Serum H-FABP and hs-TNT levels were measured at baseline.
- Cox regression analyses were used to estimate hazard ratios for non-CV death, CV death, MACE, and CHF hospitalization.
Main Results:
- Over 6.5 years, H-FABP was associated with non-CV death and MACE, even after adjusting for hs-TNT.
- Specifically, H-FABP predicted non-CV death (HR, 1.57) and MACE (HR, 1.40).
- No significant association was found with CV death or CHF hospitalization after hs-TNT adjustment.
Conclusions:
- H-FABP is associated with non-cardiovascular death and MACE in CKD patients, independent of hs-TNT.
- Further research is needed to determine if H-FABP measurement enhances cardiovascular disease risk prediction in this population.
Rationale & Objective:
Heart-type fatty acid binding protein (H-FABP) is a biomarker that has been shown to provide long-term prognostic information in patients with coronary artery disease independently of high-sensitivity troponin T (hs-TNT). We examined the independent associations of H-FABP with cardiovascular outcomes in patients with chronic kidney disease (CKD).
Study Design:
Prospective cohort study.
Setting & Participants:
4,951 patients enrolled in the German Chronic Kidney Disease (GCKD) study with an estimated glomerular filtration rate of 30-60 mL/min/1.73 m2 or overt proteinuria (urinary albumin-creatinine ratio > 300 mg/g or equivalent).
Exposure:
Serum levels of H-FABP and hs-TNT were measured at study entry.
Outcome:
Noncardiovascular (non-CV) death, CV death, combined major adverse CV events (MACE), and hospitalization for congestive heart failure (CHF).
Analytical Approach:
Hazard ratios (HRs) for associations of H-FABP and hs-TNT with outcomes were estimated using Cox regression analyses adjusted for established risk factors.
Results:
During a maximum follow-up of 6.5 years, 579 non-CV deaths, 190 CV deaths, 522 MACE, and 381 CHF hospitalizations were observed. In Cox regression analyses adjusted for established risk factors, H-FABP was associated with all 4 outcomes, albeit with lower HRs than those found for hs-TNT. After further adjustment for hs-TNT levels, H-FABP was found to be associated with non-CV death (HR, 1.57 [95% CI, 1.14-2.18]) and MACE (HR, 1.40 [95% CI, 1.02-1.92]) but with neither CV death (HR, 1.64 [95% CI, 0.90-2.99]) nor CHF hospitalizations (HR, 1.02 [95% CI, 0.70-1.49]).
Limitations:
Single-point measurements of H-FABP and hs-TNT. Uncertain generalizability to non-European populations.
Conclusions:
In this large cohort of patients with CKD, H-FABP was associated with non-CV death and MACE, even after adjustment for hs-TNT. Whether measurement of H-FABP improves cardiovascular disease risk prediction in these patients warrants further studies.
