Insights

Left ventricular global longitudinal strain (LV-GLS) was reduced in sickle cell disease (SCD) patients, indicating myocardial dysfunction. This speckle tracking echocardiography measure may aid in evaluating cardiac health in SCD, though its clinical impact requires further study.

Area of Science:

  • Cardiology
  • Hematology
  • Medical Imaging

Background:

  • Myocardial dysfunction in sickle cell disease (SCD) is debated.
  • Assessing cardiac function in SCD is challenging due to chronic overload.
  • Speckle tracking echocardiography (STE) offers a load-independent method for evaluating cardiac function.

Purpose of the Study:

  • To determine if left ventricular global longitudinal strain (LV-GLS) is abnormal in adult SCD patients.
  • To investigate correlations between LV-GLS and clinical or biological parameters in SCD.
  • To assess the utility of STE in SCD cardiac assessment.

Main Methods:

  • Prospective enrollment of 37 adult SCD patients and 34 healthy controls.
  • Echocardiography, including STE, performed on all participants.
  • Comparison of cardiac parameters between SCD patients and controls.

Main Results:

  • SCD patients exhibited higher left ventricular diameter and mass compared to controls.
  • Lower ejection fraction and longitudinal strain were observed in SCD patients.
  • LV-GLS was abnormal in 21% of SCD patients; no correlation with clinical/biological parameters found.

Conclusions:

  • LV-GLS may serve as a valuable tool for assessing cardiac function in SCD patients.
  • The clinical significance of reduced LV-GLS in SCD needs further investigation.
  • STE shows potential for early detection of cardiac changes in SCD.
