Insights
Higher levels of fatty acid-binding protein 4 (FABP4) significantly increase the risk of major adverse cardiovascular events (MACE) and cardiovascular death. This finding highlights FABP4 as a potential prognostic marker for cardiovascular disease.
Area of Science:
- Cardiovascular Research
- Biomarker Discovery
- Epidemiology
Background:
- Circulating fatty acid-binding protein 4 (FABP4) is implicated in metabolic and cardiovascular processes.
- Understanding the prognostic value of FABP4 in cardiovascular disease is crucial for risk stratification.
Purpose of the Study:
- To quantify the association between circulating FABP4 levels and the risk of major adverse cardiovascular events (MACE).
- To evaluate the relationship between FABP4 and secondary cardiovascular outcomes in prospective cohort studies.
Main Methods:
- Systematic literature search of PubMed, Embase, Web of Science, and Cochrane Library.
- Meta-analysis of 35 prospective cohort studies using random-effects models.
- Hazard ratios (HRs) and confidence intervals (CIs) were pooled; dose-response analyses were performed.
Main Results:
- Individuals in the highest FABP4 category had a 61.6% higher risk of MACE (HR=1.616).
- Elevated FABP4 levels were linked to increased risks of cardiovascular death, heart failure, and myocardial infarction.
- Each 10 ng/mL increase in FABP4 was associated with a 16.6% higher MACE risk and 13.1% higher cardiovascular death risk.
Conclusions:
- Higher circulating FABP4 levels are significantly associated with increased risks of MACE and cardiovascular death.
- FABP4 demonstrates potential as a prognostic biomarker for cardiovascular events.
- Further evaluation of FABP4 is warranted for clinical application in cardiovascular risk assessment.
Aims:
To quantify the association between circulating fatty acid-binding protein 4 (FABP4) levels and the risk of major adverse cardiovascular events (MACE) and secondary cardiovascular outcomes in prospective cohort studies.
Methods And Results:
We systematically searched PubMed, Embase, Web of Science, and the Cochrane Library from inception to 1 December 2025 for prospective cohort studies evaluating baseline FABP4 levels in relation to subsequent cardiovascular outcomes. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled using random-effects models, and dose-response analyses were performed. Thirty-five prospective cohort studies were included (PROSPERO: CRD420261291090). In the pooled analysis, participants in the highest FABP4 category, as defined within each study, had a 61.6% higher risk of MACE than those in the lowest category (HR = 1.616, 95% CI: 1.402-1.863; I2 = 35.0%). This association remained significant when FABP4 was analysed as a continuous variable (HR = 1.393, 95% CI: 1.181-1.643; I2 = 79.9%). Higher FABP4 levels were also associated with higher risks of secondary cardiovascular outcomes, including cardiovascular death, heart failure, and myocardial infarction. In linear dose-response analyses, each 10 ng/mL higher baseline FABP4 level was associated with a 16.6% higher risk of MACE and a 13.1% higher risk of cardiovascular death, with no evidence of non-linearity. Sensitivity analyses yielded similar results, and no substantial publication bias was detected for the primary MACE analysis.
Conclusion:
Higher FABP4 levels were associated with higher risks of MACE and cardiovascular death, supporting its potential relevance as a prognostic marker warranting further evaluation.
