Study Summary

This proposal will test the hypothesis that chronic treatment with sildenafil with and without the use of nitric oxide substrate, L-arginine, protects against fatty acid induced impairment of endothelial function, improves insulin-stimulated microvascular recruitment, insulin sensitivity and glucose uptake in CD36 rs3211938 G-allele carriers.

Primary Outcome

Insulin induces microvascular recruitment. Changes in MBV during Insulin infusion signifies insulin sensitivity. MBV is measured in the forearm brachioradialis muscle with contrast enhanced ultrasonography during minutes 120-150 of a hyperinsulinaemic euglycaemic (HIE) clamp (insulin infusion rate up to 80 mU/m2.min-1 ). In the last 30 minutes, L-arginine was infused (10 mg/kg/min for 30 minutes) and ultrasound measurements were repeated upon infusion completion (approximately minute 180).

Interventions

  • DRUG Sildenafil Citrate in G allele carrier
  • DRUG Sildenafil Citrate in non G allele carrier
