Surveys in the US and UK have shown that less than half of patients with high-risk conditions are prescribed aspirin. The researchers estimate that world wide 40,000 extra lives could be saved every year with 3,000 lives saved along in the UK, if every one with high-risk condition for whom aspirin was appropriate actually received it.
When used for secondary prevention, the benefit from aspirin readily outweighs possible harm from major haemorrhage (bleeding). In addition, the new study found that lower daily doses of aspirin (75-150mg) are as effective as higher doses for longer time.
In conclusion, aspirin is protective in most type of patients at increased risk of cardiovascular events, including those with myocardial infarction, ischemic stroke, unstable/stable angina, previous myocardial infarction, stroke, cerebral ischemia, peripheral artery disease or atrial fibrillation.
