Pulse wave velocity is lower in trained than in untrained sickle cell trait carriers
BACKGROUND: Sickle cell trait (SCT) is a benign condition of sickle cell disease. Nevertheless, previous reports showed
that SCT carriers have increased blood viscosity and decreased vascular reactivity compared to non-SCT carrier. The benefit
of regular exercise on vascular function has been well documented in the general population but no study focused on the SCT
PURPOSE: The aim of our study was to compare arterial stiffness and blood viscosity between trained and untrained SCT
carriers, as well as a group of untrained non-SCT.
METHODS: Arterial stiffness (finger-toe pulse wave velocity) and blood viscosity were evaluated in untrained non-SCT
carriers (n = 10), untrained SCT carriers (n = 23) and trained SCT carriers (n = 17) who reported at least 10 hours of physical
exercise per week.
RESULTS: Untrained SCT carriers had higher pulse wave velocity (p = 0.032) and blood viscosity (p < 0.001) than their
trained counterparts. In addition, untrained SCT carriers had higher blood viscosity (p < 0.001) than the untrained non-SCT
group. A positive association was noted between blood viscosity and pulse wave velocity in the whole study population.
CONCLUSION: Our study suggests that regular exercise may be beneficial for the vascular function of SCT carriers.
