Insights
Sickle cell disease (SCD) patients often have cardiac remodeling. Biomarkers like hemoglobin and HDL-C can predict left atrial enlargement, aiding early detection of heart issues in SCD.
Area of Science:
- Cardiology
- Hematology
- Biomarkers
Background:
- Sickle cell disease (SCD) is linked to cardiac remodeling, especially left atrial dilatation, a predictor of poor cardiovascular outcomes.
- Echocardiography is crucial for assessing cardiac abnormalities in SCD patients.
Discussion:
- Left atrial dilatation affects 61% of adult SCD patients.
- Dilatation is significantly associated with hemoglobin levels, hemoglobin S, HDL-C, and the atherogenic index of plasma.
- An algorithm combining low hemoglobin (≤ 9.7 g/dL) and low HDL-C (≤ 50 mg/dL) demonstrated high diagnostic accuracy.
Key Insights:
- Biomarker-based screening can identify SCD patients at risk for left atrial remodeling.
- Early detection of cardiac complications in SCD is feasible through targeted biomarker assessment.
Outlook:
- This approach is particularly valuable in resource-limited settings for proactive cardiovascular care in SCD.
- Further research can refine predictive algorithms for comprehensive SCD cardiac risk stratification.
Abstract:
Sickle cell disease (SCD) is associated with cardiac remodeling, particularly left atrial dilatation, which may predict adverse cardiovascular outcomes. This study assessed cardiac abnormalities using echocardiography in 59 adult SCD patients and explored biomarkers predictive of left atrial remodeling. Left atrial dilatation was found in 61% of patients and significantly associated with hemoglobin, hemoglobin S, HDL-C, and the atherogenic index of plasma. An algorithm combining hemoglobin ≤ 9.7 g/dL and HDL-C ≤ 50 mg/dL showed high-diagnostic performance. These findings support biomarker-based screening as a useful tool in resource-limited settings for early detection of cardiac complications in SCD.
