Canadian Wildfire Smoke Linked to Surge in U.S. Heart and Lung Medical Visits

A study finds a nearly 20% increase in cardiopulmonary-related doctor visits in Baltimore during high-smoke days in June 2023.

Researchers identified six 'hotspot' days in June 2023 when wildfire smoke from Western Canada caused dangerous air quality in Maryland.
Medical visits for heart and lung conditions in Baltimore rose by 18% on these days compared to June 2018 and 2019.
Outpatient visits for cardiopulmonary issues surged by 55%, with older, non-smoking, and more affluent patients disproportionately affected.
The study highlights potential barriers to healthcare access for economically disadvantaged patients during poor air quality events.
Experts stress the need for anticipatory care, such as telehealth, to mitigate health risks during future extreme wildfire events.
