American Heart Association warning: Here’s what those impacted by wildfire smoke need to know

Key Points:

• The American Heart Association (AHA) warns that smoke exposure from Canadian wildfires can cause or worsen heart problems, with studies linking it to increased risks of sudden cardiac arrest and higher emergency room visits for cardiovascular issues.
• Smoke drifting into Michigan has led to hazardous air quality, with research showing that wildfire smoke significantly raises same-day hospitalizations for unstable chest pain and other heart-related conditions.
• AHA recommends reducing smoke exposure by staying indoors with windows closed, using high-efficiency air filters, avoiding exertion, staying hydrated, and bringing pets indoors.
• Exposure to heavy wildfire smoke increases out-of-hospital cardiac arrest risk by up to 70%, with ER visits for heart attacks and ischemic heart disease rising significantly, especially among older adults and those with preexisting cardiovascular conditions.
• The AHA urges people to recognize heart attack symptoms—such as chest discomfort, pain in upper body areas, shortness of breath, and other signs—and to call 911 immediately during high smoke exposure; knowing CPR can greatly improve survival chances.
