A myocardial infraction or a heart attack is permanent damage to the heart muscle. It occurs when the flow of oxygen-rich blood to heart muscle gets suddenly blocked by which the heart can’t get oxygen. Various symptoms include pain or discomfort in one or both the arms that spread to shoulders, upper back, neck or jaw, a general sense of anxiety, shortness of breath, stomach or abdominal pain, weakness and overwhelming fatigue, swelling of the ankles and lower legs, etc.
A heart attack is a medical emergency so should call the ambulance. If the causality is not allergic to aspirin and its easily available than give them a tablet ideally 300mg to slowly chew and swallow while waiting for the ambulance to arrive. The aspirin will help to reduce the risk of heart attack by thinning the blood. The two main treatments include: using medication to dissolve blood clots, surgery to restore blood to the heart.
Canada is making progress in preventing heart attacks, according to a report released. The Health Indicators 2009 report by the Canadian Institute for Health Information suggested the rate of heart attacks in Canada (i.e. the number of people per 100,000 hospitalized for heart attacks) dropped 13 per cent between 2003-2004 and 2007-2008. There were 251 hospitalizations for heart attacks per 100,000 people the 1st year, which dropped to 219 hospitalizations per 100,000 last year. The rates of deaths from heart attack within 30 days of being admitted to hospital also dropped, decreasing by 11 per cent between 2003 and 2008.
