Ward MM Newsletter April 2017
An acute myocardial infarction (AMI) or heart attack occurs when blood flow to the heart becomes partially or fully occluded, resulting in irreversible necrosis of myocardial tissue. Much like angina which was discussed in last month’s newsletter, coronary heart disease is also the primary cause of myocardial infarctions. In Australia, coronary heart disease is responsible for around 20% of all deaths. Of those people who suffer from an AMI, approximately 25% will die from the initial event with a further 10% dying within 2 years. Younger men are significantly more likely to suffer from a heart attack when compared to women however the rates of AMI are similar amongst men and women >70 years of age.
