Limb muscle hemodynamics and arterial distensibility depend on atmospheric pressure in hypertensive men.

Objective: To verify whether peripheral blood circulation and arterial wall distensibility are influenced by atmospheric pressure (AtPr) and to examine if their association is dependent on age and/or sex.

Methods: Associations among natural AtPr levels (on the examination day as well as 1 and 2 days prior), limb muscle hemodynamics, and distensibility of conduit arteries were retrospectively examined in an observational study of 276 untreated patients with primary moderate hypertension (mean age 56.4 years, 194 men).
