Myocardial Infarction Law and Legal Definition
Myocardial infarction is the death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Since coronary arteries are blood vessels that supply the heart muscle with blood and oxygen, blockage of a coronary artery deprives the heart muscle of blood and oxygen, causing injury to the heart muscle.
Under Workers' compensation, benefits awarded where work precipitates infarction. Where myocardial infarction is shown to have been aggravated or precipitated by the employment, benefit is awarded. [Kempner's & Dodson Ins. Co. v. Hall, 7 Ark. App. 181 (Ark. Ct. App. 1983)]
