Insights
Serum heart-type fatty acid-binding protein (H-FABP) levels are elevated in acromegaly patients. Increased H-FABP may indicate impaired myocardial performance in individuals with acromegaly.
Area of Science:
- Endocrinology
- Cardiology
- Biochemistry
Background:
- Heart-type fatty acid-binding protein (H-FABP) is released upon myocardial injury.
- H-FABP is linked to various cardiovascular and other conditions.
Purpose of the Study:
- To investigate serum H-FABP levels in patients diagnosed with acromegaly.
Main Methods:
- Serum H-FABP was measured using ELISA in 30 acromegaly patients and 55 controls.
- Spearman's correlation test was employed.
Main Results:
- Acromegaly patients exhibited significantly higher serum H-FABP levels compared to controls (17.40 ± 10.70 vs. 8.30 ± 7.20, p<0.001).
- A positive correlation was observed between serum H-FABP and left ventricular end-systolic diameter (r=0.483, p=0.004).
Conclusions:
- Patients with acromegaly demonstrate elevated serum H-FABP levels.
- Serum H-FABP may serve as a biomarker for myocardial performance in acromegaly.
Background:
Heart-type fatty acid-binding protein (H-FABP) is a major cytoplasmic low molecular weight protein and released into the circulation when the myocardium is injured. Previous studies have demonstrated that H-FABP is closely associated with acute coronary syndrome, hypertrophic and dilated cardiomyopathy, heart failure, stroke, obstructive sleep apnea syndrome, and pulmonary embolism. The aim of this study was to investigate serum H-FABP value in patients with acromegaly.
Methods And Results:
We measured serum H-FABP levels in 30 consecutive patients with acromegaly, and 55 age-matched control subjects by using a sandwich enzymelinked immunosorbent assay. Serum H-FABP levels were significantly higher in patients with acromegaly than in control subjects (17.40 ± 10.70, and 8.30 ± 7.20, respectively) (p<0.001). A significant positive correlation was found by Spearman's correlation test between serum H-FABP levels and left ventricular end-systolic diameter (r=0.483, p=0.004).
Conclusion:
Patients with acromegaly have increased levels of H-FABP. Serum H-FABP levels might be a marker of myocardial performance in patients with acromegaly.
