New Study Study Finds Small Increased Risk of Heart Attack in Patients Treated with Pradaxa

In a new study published in the Archives of Internal Medicine, Pradaxa (Dabigatran) was associated with an increased risk of heart attack and acute coronary syndrome, a condition brought on by sudden, reduced blood flow to the heart. Pradaxa is a blood thinner that is approved by the FDA to lower risk of stroke in patients with a history of atrial fibrillation, a type of abnormal heart rhythm.

According to the study researchers, the actual increase in the number of heart attacks and acute coronary syndrome events was very small and is outweighed by the benefit of the drug's ability to reduce the number of strokes. Heart attacks and acute coronary syndrome events occurred in 1.19% of the Pradaxa patients, and in 0.79% of the control-group patient.
