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.
For three decades, the annual number of deaths was around 60,000. In recent years, it has increased. In 2012, for the first time over 64,000 deaths were recorded. Whereas the number of deaths of persons aged under 80 is decreasing, the trend is the opposite for persons aged over 80. This can be explained by the change in the population's demographic structure. A clear decline in the standardised mortality rates by age can be observed.
