Heart attacks at work at Work — Injury Statistics and Claims Information
Heart attacks at work at Work
Annual incident rates are currently decreasing
OSHA has recorded 156 severe cases of ischemic heart disease and heart attacks in workplace settings. These incidents primarily affect the internal cardiovascular structures of the chest, leading to immediate and life-threatening health crises for workers.
A cardiac event at work often results in long-term functional limitations and significant impacts on a worker's future earning capacity. The sudden nature of these injuries frequently requires emergency surgery and prolonged recovery periods that disrupt both professional and personal life.
What's Driving the Trend?
The 10-year trend shows a 33.3 percent decrease in reported incidents, though year-over-year data indicates significant volatility. Persistent safety gaps related to physical overexertion and exposure to extreme environmental conditions continue to drive these severe medical reports.
Retail trade, construction, and health care industries account for the highest volume of cases. These sectors often involve high-stress environments or physically demanding tasks that place excessive strain on the cardiovascular systems of employees.
How Heart attacks at work Happen at Work
Top causes based on OSHA incident reports
Overexertion remains the primary driver of workplace cardiac events, accounting for over 60 percent of reported incidents. Whether through heavy manual material handling, repetitive physical labor, or intense workplace stress, these activities frequently trigger acute cardiovascular distress.
| Cause | Incidents | |
|---|---|---|
| 1 | Multiple types of overexertion while moving or manipulating external object(s) | 26 |
| 2 | Overexertion while moving or manipulating external object(s)— unspecified | 22 |
| 3 | Overexertion while materials moving by hand | 10 |
| 4 | Violent acts by other person— unspecified | 7 |
| 5 | Hitting, kicking, beating by other person | 6 |
| 6 | Exposure to environmental heat | 5 |
| 7 | Overexertion while moving or manipulating external object(s)— n.e.c. | 3 |
| 8 | Twisting, reaching, bending | 3 |
Why This Matters for Your Case
Employers are required to maintain safe working conditions under the General Duty Clause of the OSH Act. When incidents involve environmental heat, employers must comply with heat illness prevention standards, and in cases involving violent acts, they must adhere to workplace violence prevention guidelines to mitigate foreseeable cardiac triggers.
Industries with Most Heart attacks at work
Where these injuries occur most frequently
Retail trade, construction, and health care represent the highest risk sectors, collectively accounting for nearly 50 percent of all reported cardiac incidents. These industries often require workers to perform strenuous physical tasks or operate under high-pressure conditions that can exacerbate underlying cardiovascular vulnerabilities.
High-Risk Industries and Your Rights
Employers in these high-risk sectors must adhere to 29 CFR 1904.39 for mandatory incident reporting and maintain compliance with standards regarding physical exertion limits and environmental safety. Failure to provide adequate rest breaks or protection from extreme heat may constitute a failure to provide a safe workplace under federal regulations.
Real Incident Reports
From actual OSHA investigation files
Reported incidents reveal a pattern of cardiac events triggered by extreme physical exertion, such as snow shoveling or wildfire suppression, as well as stress-induced episodes following workplace violence or aggressive patient encounters. These narratives demonstrate that cardiac events often occur during routine tasks or emergency response situations where physical and emotional strain peaks.
"An employee sustained a heart attack after shoveling snow off a sidewalk. The employee was hospitalized."
"An employee was delivering food to a customer's home. She walked up to the front door and a dog came running out from the house. The dog bit the employee's left knee. The employee was hospitalized with a stress-induced heart attack."
"An employee had been doing yard work and was mowing a lawn with a push mower. The employee had a heart attack."
"An employee had been assisting fire crews with an active wildfire. The employee suffered a heart attack and was hospitalized for surgery."
"An employee was attempting to escape from an aggressive patient's path and suffered a cardiac event as the patient was being restrained by other staff. The employee was hospitalized. "
"An employee was detecting the lower explosive limit (LEL) and initiated a shutdown of the loading rack, stopping the flow to the rail car. The employee's personal four-gas monitor began to alarm for LEL and he evacuated north toward the end of the loading rack. The employee had difficulty catching his breath and had a rapid heart rate after he evacuated the area. The employee was hospitalized for atrial fibrillation."
"On January 18, 2024, at 11:15 AM, an employee was delivering feed to a chicken farm when their truck became stuck in snow and ice. The employee manually dug out the snow from around the tires, applied tire chains, and was able to drive to the main road. At the main road the employee removed the chains and drove to the mill. Upon arrival at the mill and walking to the office, the employee experienced chest pain and was hospitalized for a heart attack."
"On October 24, 2023, an employee suffered a heart attack while completing physical fitness testing on a designated obstacle course."
"An injured employee was found outside next to the building approximately 15 feet from the cab of his truck. The employee sustained neck injuries from a possible fall due to snow and ice and went into cardiac arrest."
"An employee sustained a heart attack while moving bags of soil weighing 25 to 50 pounds."
