The Cardiovascular Benefits of Reducing Personal Exposure to Air Pollution

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

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.

Inclusion Criteria:

• Healthy volunteers

Exclusion Criteria:

• Current smokers
• Significant occupational exposure to air pollution
• Regular medication use (except oral contraceptive pill)
• Intercurrent illness
