Low-dose aspirin improvesendothelial function in
hypertensionLow-dose aspirin may restore endothelium-
dependent vasodilation in patients with hypertension,according to researchers from Japan.
The researchers studied 18 patients with essentialhypertension and 10 volunteers without hypertension,before and 8 weeks after administration of aspirin[acetylsalicylic acid] 162 mg/day.
Flow-mediated vasodilation was lower in the patientswith hypertension than in the control group (6.4 vs11.3%), but glyceryl trinitrate-induced (endothelium-independent) vasodilation was similar in the twogroups. Aspirin significantly increased flow-mediatedvasodilation in the patients with hypertension from 6.4to 10.4%, and also increased production of cyclicguanosine monophosphate.
These findings suggest that increased nitric oxideproduction, resulting from cyclo-oxygenase inhibition,may be involved in the improvement of endothelialfunction seen with low-dose-aspirin, comment theresearchers.Monobe H, et al.
