Feasibility of a Multifaceted Program to Reduce Cardiovascular Complications of Air Pollution

"A hybrid strategy inclusive of:~1. A one-page flashcard describing the adverse cardiovascular effects of air pollution and individual-level strategies to mitigate these effects~2. Alerting patients on polluted days (defined as air quality index (AQI) ≥ 131 \[33\]) by sending cell phone text messages and recommending to not go outdoors or minimize outdoor activities (especially exercising) on those days. This will also be accompanied by periodic phone calls to ascertain that the patients receive the messages and are attentive to them.~3. Wearing KN-95 facemasks (provided by the investigators of this study) as a physical barrier against air pollution on highly polluted days (defined as AQI ≥ 131) in case the patient cannot avoid going outdoors~4. Dietary intervention by encouraging patients to consume citrus fruits during days with AQI ≥ 131"
