Myocardial Infarction is a life-threatening medical condition that is characterized by the death of heart muscles due to sudden blockage of a coronary artery which cuts off blood supply to the heart muscles. The blockage usually occurs in the lumen of a coronary artery that is already narrowed by fatty plaque from atherosclerosis, which becomes completely blocked by a blood clot or an arterial plaque. The heart muscles that are deprived of oxygen die in the process, giving rise to the crushing chest pain symptom of a myocardial infarction. It is a medical emergency that requires immediate medical treatment to prevent permanent damage to large area of the heart and premature death. Although it is commonly known that men have a higher risk of atherosclerosis than women, women past menopause have around the same risk as men as they no longer have high level of estrogen, a female hormone known to prevent atherosclerosis, in their blood. As such, women are also of higher risk of developing coronary artery disease once they reach menopause, which in turn increases their risk of having myocardial infarction.
