Heart at Work — Injury Statistics and Claims Information
Heart at Work
Cardiac workplace incidents remain a persistent risk
OSHA has recorded 119 severe cases involving the heart, with ischemic heart disease and heart attacks accounting for 92.4% of these incidents. These events often result in immediate hospitalization and long-term health complications for the affected worker.
The heart is essential for all physical labor, and damage to this organ can permanently limit a worker's ability to perform strenuous tasks. Beyond the immediate medical crisis, these injuries frequently lead to a total loss of earning capacity and a significant reduction in quality of life.
What's Driving the Trend?
While annual case counts have fluctuated, the data shows that cardiovascular stress is a recurring issue in high-exertion environments. Overexertion while moving or manipulating objects accounts for over 50% of all reported incidents, indicating a clear link between physical labor demands and cardiac events.
Retail trade and construction lead the industry list, representing 18.5% and 16.0% of cases respectively. These sectors often involve repetitive heavy lifting and exposure to environmental extremes, which place direct, unmanaged stress on the cardiovascular systems of employees.
How Heart Injuries Happen
Top causes based on OSHA incident reports
Cardiac injuries at work are rarely the result of a single accident, but rather the culmination of extreme physical strain. Overexertion while moving objects is the primary driver, appearing in 53.6% of all reported cases, followed by environmental heat exposure and violent acts.
| Cause | Incidents | |
|---|---|---|
| 1 | Multiple types of overexertion while moving or manipulating external object(s) | 23 |
| 2 | Overexertion while moving or manipulating external object(s)— unspecified | 21 |
| 3 | Exposure to environmental heat | 5 |
| 4 | Hitting, kicking, beating by other person | 5 |
| 5 | Overexertion while materials moving by hand | 5 |
| 6 | Violent acts by other person— unspecified | 4 |
| 7 | Walking, without other incident | 3 |
| 8 | Exposure to harmful substances— unspecified | 2 |
Why This Matters for Your Case
Employers are required under 29 CFR 1904.39 to maintain safe working conditions that prevent undue physical stress. When a workplace fails to implement proper ergonomic controls or heat illness prevention plans, they may be in violation of the General Duty Clause of the OSH Act, which mandates a workplace free from recognized hazards causing death or serious physical harm.
Industries with Most Heart
Where these injuries occur most frequently
Retail trade accounts for 18.5% of cardiovascular injuries, largely due to the high-pressure environment of manual material handling and inventory management. Construction follows closely at 16.0%, where workers are frequently subjected to intense physical labor and fluctuating environmental temperatures that can trigger cardiac distress.
High-Risk Industries and Your Rights
Employers in these sectors must adhere to 29 CFR 1910.132 regarding personal protective equipment and 29 CFR 1910.141 regarding sanitation and environmental conditions. Proper training on safe lifting techniques and mandatory rest periods in high-heat environments are essential components of a compliant safety program.
Real Incident Reports
From actual OSHA investigation files
The reported incidents reveal a pattern of cardiovascular failure triggered by extreme physical exertion, environmental heat, and high-stress encounters. Whether it is a worker shoveling snow, assisting in wildfire suppression, or reacting to a sudden violent threat, the common thread is a sudden, severe cardiac event requiring immediate emergency hospitalization.
"An employee was walking down a roadway between two buildings when they slipped on packed snow and ice, falling to the ground and suffering sternum and myocardial contusions. The employee was hospitalized. "
"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."
