Firefighter Heart Health: What Does New Guidance Change?

Why do firefighters and emergency responders need specialized heart care?

Firefighters and emergency medical responders belong to a broader occupational group known as tactical athletes. Heavy equipment, intense exertion and extreme conditions can place substantial demands on their cardiovascular systems. The new guidance introduces Tactical Clinical Management, a framework that considers a person's heart condition alongside the tasks and circumstances of their work. During a rescue, sudden incapacity can endanger colleagues and the people awaiting help, making occupational context central to medical decisions.

The evidence connecting firefighting duties with cardiac events predates this statement. A study published in the New England Journal of Medicine in 2007 examined US firefighter deaths from 1994 through 2004. Fire suppression accounted for approximately 32% of coronary heart disease deaths, despite representing an estimated 1% to 5% of duty time. These historical findings show an association between demanding tasks and fatal events; they do not describe today's death rate or prove that a particular screening program prevents deaths.

What cardiovascular screening does the new guidance recommend?

The statement emphasizes screening before participation. It recommends an electrocardiogram, or ECG, for tactical athletes younger than 40 whose roles involve substantial cardiovascular strain or critical responsibilities; an ECG is also considered reasonable for others. An ECG records the heart's electrical activity. The assessment also needs to account for familiar cardiovascular risks, including high blood pressure, abnormal cholesterol, diabetes and smoking.

Functional testing should reflect actual job duties. Clinicians therefore need information about exertion, equipment, working conditions and access to emergency care when interpreting a person's capacity. The document addresses conditions ranging from heart muscle disease and abnormal rhythms to coronary disease. An abnormal finding requires further evaluation and a decision tied to the person's condition and work demands. [ACC/AHA scientific statement](https://www.jacc.org/doi/10.1016/j.jacc.2026.07.003).

How can emergency services reduce cardiovascular risk?

Prevention extends beyond a screening appointment. The National Institute for Occupational Safety and Health has long recommended medical evaluation programs, comprehensive fitness and wellness support, and measures to reduce cardiovascular strain during firefighting. Its recommendations also include smoking cessation support and reducing smoke exposure. These measures make cardiovascular protection an ongoing responsibility shared by workers, clinicians and departments, rather than an issue considered only when someone applies for the job. [NIOSH prevention recommendations](https://www.cdc.gov/niosh/bulletin/2007/firefighter-fatalities.html).

The new statement recommends that automated external defibrillators, or AEDs, be accessible within three minutes during graded, timed or other high-risk physical training. Emergency action plans should be established and practiced because screening cannot identify every person who will experience cardiac arrest. [ACC/AHA scientific statement](https://www.jacc.org/doi/10.1016/j.jacc.2026.07.003). This is clinical guidance rather than a trial demonstrating fewer deaths. Its authors call for better research into screening and risk prediction for these workers.
