Cardiovascular Events Remain Top Cause of Firefighter Deaths in 2025
By Southern Maryland Volunteers
January 15, 2026
Cardiovascular events were once again the leading cause of on-duty firefighter fatalities in 2025, highlighting an urgent and ongoing health concern within the fire service.
Of the 76 firefighters who lost their lives in the line of duty last year, half died from cardiac-related events such as heart attacks and cardiac arrest. These incidents were most often linked to stress and overexertion during emergency operations, training, and other physically demanding activities.
Key Trends from 2025 Line-of-Duty Deaths
Cardiovascular events accounted for the highest percentage of firefighter fatalities.
Firefighters aged 41 and older represented the majority of those lost, with about 75% of deaths occurring in this age group.
Fatal incidents spanned a variety of operations, including fire suppression, EMS response, training exercises, and vehicle operations.
Prioritizing Health and Wellness
The demanding nature of fire service work places significant physical strain on the heart, particularly during high-stress responses. These findings emphasize the critical importance of health and wellness programs aimed at reducing risk factors and supporting firefighter longevity.
Departments across the country are reinforcing efforts in the following areas:
Regular cardiovascular health screenings
Structured fitness and exercise programs
Stress management resources
Nutrition and lifestyle support
Compliance with national firefighter health standards
