Recent research on the effects of aspirin has revealed concerning results. Many older individuals at risk of heart disease and stroke take low dose aspirin to prevent blood clots, but this study suggests it may actually increase the risk of bleeding in the skull.
The Trial: Aspirin vs. Placebo
Researchers analyzed data from 13 studies with over 130,000 participants and found that those taking a low dose of aspirin had a higher risk of bleeding in the head compared to those who took a placebo. This includes a statistic equivalent to 2 out of every 1,000 people experiencing this form of bleeding.
This type of head bleeding, known as a cerebral or intracranial hemorrhage, can cause brain damage due to lack of oxygen supply to the brain.
Some of the main causes of intracranial hemorrhage include head trauma, high blood pressure, blocked arteries, smoking, excessive alcohol consumption, and treatment with anticoagulant therapy (blood thinners).
Aspirin: The Recommended Blood Thinner
Aspirin, commonly prescribed for heart and blood conditions, prevents platelets from clotting. However, in the presence of atherosclerotic plaques, aspirin’s blood-thinning effect may not be beneficial for preventing heart attacks or strokes in individuals without a history of these conditions.
Should We Still Use Aspirin or Not?
Following these findings, guidelines from the American College of Cardiology emphasize that aspirin should only be prescribed to people at the highest risk of cardiovascular disease and a very low risk of bleeding. It’s important for individuals to assess their risk of head bleeding with their healthcare practitioners, especially if they have certain medical conditions or are taking specific medications.
It is crucial to consult a healthcare practitioner before starting or stopping any medication. Lifestyle habits, blood pressure control, and cholesterol management are emphasized as more important than recommending aspirin for preventive purposes.
