Low Dose Aspirin May Reduce Blood Clot Risk Associated with VTE

The Centers for Disease Control and Prevention (CDC) recommends that a daily aspirin regimen is taken for those who have already experienced a heart attack, stroke, angina or peripheral vascular disease. However, previous studies have also shown that taking aspirin frequently can increase the risk of stomach ulcers and stomach bleeding.

Now, recent findings have revealed that taking a daily amount of aspirin could help prevent venous thromboembolism (VTE) in some individuals--a condition in which blood clots break off and travel to the lungs, blocking the arteries.

For the study, researchers at the University of Sydney Australia looked to determine if aspirin could be used as an alternative to anticoagulants for the treatment of blood clots.

Researchers conducted an analysis of two studies that involved a total of 1,224 patients with VTE who were given 100 mg of aspirin a day for a minimum of 2 years. During the follow-up period, researchers found that aspirin helped reduce the risk of recurrent blood clots in patients by about 42 percent.

The findings are certainly promising for those who be at greater risk for this health issue. Research shows that individuals who have had major orthopaedic surgery of the lower extremity and major surgery for cancer may be at increased risk of this health issue. Those who have been immobilized for an acute medical illness may also be at a greater risk for VTE than the general population.

However, researchers note that aspirin will not work as effectively as anticoagulant therapy and should not be taken in place of certain medications.
