A new study published in JAMA suggests that the common practice of prescribing anticoagulants to individuals who have experienced unexplained strokes may not be as beneficial as previously thought. The findings challenge the assumption that anticoagulants could prevent additional strokes in individuals with atrial cardiopathy, a heart condition resembling atrial fibrillation.
Lead author Mitchell Elkind, Professor of Neurology at the Vagelos College of Physicians and Surgeons, explained that while anticoagulants have been effective in preventing strokes in individuals with atrial fibrillation, the study found no significant difference in stroke rates between patients with atrial cardiopathy who were given the anticoagulant apixaban and those who received aspirin, the current standard of care.
The trial, which involved 1,015 participants, revealed a stroke rate of 4.4% among patients treated with apixaban, similar to those treated with aspirin. These results indicate that anticoagulants may not offer added benefits over aspirin for individuals with atrial cardiopathy, suggesting that they should be reserved for patients with definitive evidence of atrial fibrillation.
Elkind emphasized the importance of these findings in guiding clinical practice, noting that while the results may be disappointing for physician-scientists, they provide valuable insights for neurologists managing patients with unexplained strokes. With approximately one-third of strokes having unknown causes, understanding the most effective treatment strategies is essential for preventing subsequent strokes and improving patient outcomes.
The study also sheds light on the underlying mechanisms of unexplained strokes, revealing changes in the heart that resemble those seen in atrial fibrillation. Despite not confirming the initial hypothesis, the study offers valuable information for clinicians and researchers, highlighting the need for further investigation into optimal treatment approaches for individuals with atrial cardiopathy.
As researchers continue to explore the complexities of stroke prevention, Elkind and his team remain committed to refining treatment strategies and improving outcomes for patients with atrial cardiopathy and other stroke-related conditions.
