Acute myocardial infarction (AMI), commonly known as a heart attack, results from the interruption of blood supply to a part of the heart, causing heart cells to die. The resulting ischemia (restriction in blood supply) and ensuing oxygen shortage, if left untreated for a sufficient period of time, can cause damage or death (infarction) of heart muscle tissue (myocardium).
Myocardial infarction results from atherosclerosis. Smoking appears to be the cause of about 36% of coronary artery disease and obesity 20%. Lack of exercise has been linked to 7-12% of cases. Job stress appear to play a minor role accounting for about 3% of cases.
There is a 5% chance you will die from a heart attack in the European Union but rates vary widely between countries. The lowest age-standardized rates are found in Denmark and Norway and the highest rate is in Belgium. On the other hand, every fifth Mexican diagnosed with a heart attack dies, according to OECD.
