Fenofibrate treatment significantly improved microcirculation in hyperlipidemic patients by reducing triglycerides and fibrinogen. This enhances capillary blood flow, likely through reduced plasma viscosity and improved endothelial function.

Area of Science:

  • Cardiovascular Medicine
  • Pharmacology
  • Microcirculation Research

Background:

  • Hyperlipidemia is associated with impaired microvascular function.
  • Dyslipidemia affects endothelial function and plasma viscosity.

Purpose of the Study:

  • To investigate the effects of fenofibrate on microcirculation in patients with hyperlipidemia.
  • To assess changes in lipid profiles and microcirculatory parameters.

Main Methods:

  • A study involving 16 hyperlipidemic patients treated with fenofibrate (200 mg/day for 6 weeks).
  • Nailfold capillaroscopy was used to evaluate microcirculation before and after treatment.
  • Measurements included lipid levels, fibrinogen, and capillary blood cell velocity during postreactive hyperemia.

Main Results:

  • Fenofibrate significantly reduced triglycerides, LDL-cholesterol, and apolipoprotein B.
  • A significant decrease in fibrinogen levels was observed.
  • Time to peak capillary blood cell velocity during postreactive hyperemia markedly decreased, indicating improved microcirculation.

Conclusions:

  • Fenofibrate treatment improves microcirculation in hyperlipidemic patients.
  • Potential mechanisms include reduced plasma viscosity due to lower fibrinogen and improved endothelial function via nitric oxide (NO) pathway.
  • Fenofibrate offers a therapeutic benefit beyond lipid reduction by enhancing microvascular perfusion.
