Summary

This study investigated whether patients with an implanted cardioverter defibrillator (ICD) who followed advice to exercise indoors on high air pollution days had reduced adverse impacts on cardiovascular measures compared with those who exercised outdoors on those days. Participants were randomly divided into the control and intervention groups. Both groups walked for 30 minutes outdoors every day for maximum 70 days, and their blood pressure, pulse rate and blood oxygen saturation pre- and post-exercise were measured. Hourly ambient concentrations of air pollutants were collected. On days forecast with Air Quality Health Index was equal to or higher than 5, the intervention group was advised to exercise indoors.

Intervention group

When Air Quality Health Index is below level 5, the intervention group did daily mild exercise (walking) outdoors for 30 minutes. When Air Quality Health Index is equal to or above level 5, the group is advised to do mild exercise indoors for 30 minutes.
