Cardiovascular consequences of sickle cell disease

Area of Science:

• Hematology
• Cardiovascular Medicine
• Biophysics

Background:

• Sickle cell disease (SCD) is an inherited disorder stemming from a beta globin gene mutation.
• This mutation causes hemoglobin polymerization, deforming red blood cells and impairing blood flow.
• SCD leads to vaso-occlusion, stroke, pain crises, and organ damage, significantly impacting the cardiovascular system.

Purpose of the Study:

• To review the cardiovascular consequences of sickle cell disease.
• To explore connections between SCD-related vasculopathy and cardiovascular complications.
• To highlight biophysical properties and engineering tools for SCD characterization and discuss therapeutic implications.

Main Methods:

• Literature review focusing on cardiovascular aspects of sickle cell disease.
• Analysis of biophysical properties and engineering tools used in SCD research.
• Discussion of current and potential therapies for SCD and their impact on cardiomyopathy.

Main Results:

• SCD significantly strains the cardiovascular system through elevated cardiac output, endothelial activation, and vaso-occlusion.
• Cardiovascular complications are intrinsically linked to the vasculopathy characteristic of SCD.
• Biophysical characterization aids in understanding disease mechanisms and evaluating therapeutic efficacy.

Conclusions:

• Sickle cell disease presents multifaceted cardiovascular challenges beyond its definition as a red blood cell disorder.
• Understanding the interplay between sickling, vasculopathy, and cardiovascular strain is crucial for comprehensive patient care.
• Therapeutic strategies must consider the profound impact of SCD on the heart and vasculature.
