A heart attack refers to the death of heart muscle tissue caused by a sudden arterial blockage, which is usually the formation of a clot on top of a pre-existing buildup of cholesterol, called a plaque. The most common symptoms associated are chest, arm and neck pain. Current technology allows the re-opening of blocked arteries to preserve heart muscle and thereby heart function. It is therefore imperative that medical help be sought as soon as chest pain and associated symptoms occur.
