Association between pulmonary function and cardiac enzymes in sickle cell disease

Area of Science:

• Cardiology
• Pulmonology
• Hematology

Background:

• Sickle cell disease (SCD) is a multi-organ affecting condition with limited data on lung function and cardiac marker associations.
• Existing research suggests a link between reduced pulmonary function and cardiac dysfunction.
• This study investigates the relationship between pulmonary function and cardiac markers in SCD patients.

Purpose of the Study:

• To examine the association between pulmonary function parameters and cardiac markers in patients with sickle cell disease.
• To identify potential cardiac implications of impaired lung function in SCD.

Main Methods:

• A cross-sectional study comparing 117 SCD patients with 58 healthy controls.
• Genotyping using cellulose acetate electrophoresis.
• Measurement of cardiac enzymes (LDH, CK-MB) and lung function tests (FEV1) using spirometry.
• Lung disease categorization based on Global Lung Initiative criteria.

Main Results:

• Elevated CK-MB and LDH prevalence was higher in SCD patients (76.92% and 9.40%) compared to controls (51.72% and 0%).
• Lung restriction was the most prevalent impairment in both groups (30.77% in SCD, 15.52% in controls).
• Reduced FEV1 was significantly associated with a 3.5-fold increased odds of elevated CK-MB in SCD patients (OR 3.35, p=0.015).

Conclusions:

• Reduced FEV1, indicating airflow impairment, is associated with elevated CK-MB in sickle cell disease patients.
• This association suggests potential cardiomyocyte damage in SCD patients with airflow limitations.
• Further research is warranted to elucidate the mechanisms linking pulmonary and cardiac dysfunction in SCD.
