The Cardiovascular Benefits of Reducing Personal Exposure to Air Pollution

Beneficial Cardiovascular Effects of Reducing Exposure to Particulate Air Pollution With a Simple Facemask

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 15 (actual)
• Sponsor: University of Edinburgh · Academic / Other
• Sex: All
• Age: —
• Healthy volunteers: Accepted

Summary

Exposure to air pollution is an important risk factor for cardiovascular morbidity and mortality, and is associated with increased blood pressure, reduced heart rate variability, endothelial dysfunction and myocardial ischaemia. The study objectives were to assess the potential cardiovascular benefits of reducing personal particulate air pollution exposure by wearing a facemask in healthy volunteers.

Conditions

• Blood Pressure
• Heart Rate Variability

Interventions

Type	Name	Description
DEVICE	Face mask (Dust Respirator)	Subjects to wear a simple face mask for 24 hours prior to the study day and the 24 hours of the study day. They will be instructed to wear the mask as much as possible when indoors and at all times when outdoors.
OTHER	No Face mask	Subjects will not wear a face mask to reduce their personal exposure to air pollution
