Which of the following would typically NOT cover a heart attack under workers' compensation?

In the context of workers' compensation, certain conditions and behaviors can affect the coverage of health incidents like a heart attack. Intoxication and horseplay that directly contribute to the heart attack represent actions or circumstances that can be seen as willful misconduct or deviations from job responsibilities. Since workers' compensation is designed to cover injuries that occur as a result of work-related activities, behaviors such as intoxication or engaging in horseplay typically fall outside the acceptable parameters for coverage.

This is because workers' compensation systems are predicated on the idea that the injury should be a direct result of the work environment or duties, and actions that jeopardize safety or violate company policy do not meet that criterion. Thus, a heart attack that occurs under the influence of substances or during a moment of reckless behavior would not be granted coverage, as the cause of the event can be directly attributed to these inappropriate actions rather than the individual's work duties or environment.
