A heart attack occur when the muscle of the heart is damaged by blockage of one of its fuel pipes; the fuel is oxygen carried in the blood, and the pipes are the arteries; in the case of the heart they are called coronary arteries. These arteries may become narrowed and this may eventually lead to a complete blockage. That part of the heart muscle supplied by a blocked artery will be irreversibly damaged and although this may not necessarily cause any problems with the heart pumping action, there may be a variety of short-term problems which can be potentially serious. For this reason, patients are best nursed in hospital where they can be under continuous observation for the first few days.
