Anticoagulation in Subclinical AF
My fourth study comes from the stroke-prevention field, published in The New England Journal of Medicine. I think you are aware of subclinical atrail fibrillation. These are high-frequency episodes in ECG, usually identified by pacemakers or ECG monitoring systems. The international ARTESIA study included more than 4000 patients randomized either to apixaban 5 mg twice daily or aspirin 81 mg.
After 3.5 years, the investigators showed a small but significant decrease in the rate of stroke, with a relative risk reduction of 37%, but also, unfortunately, a significantly increased risk for major bleeding with apixaban. This means that we need a careful discussion with the patient, the family, and the GP to decide whether these patients should be anticoagulated or not.
Migraine and Depression
My final study, published in the European Journal of Neurology, deals with the comorbidity of depression and migraine. This study in the Netherlands included 108 patients treated with erenumab and 90 with fremanezumab; 68 were controls.
They used two depression scales. They showed that treatment with the monoclonal antibodies improved at least one of the two depression scales. I think this is an important study because it indicates that you can improve comorbid depression in people with severe migraine, even if this study did not show a correlation between the reduction in monthly migraine days and the improvement of depression.
What we learned for clinical practice is that we have to identify depression in people with migraine and we have to deal with it. Whether it’s with the treatment of monoclonal antibodies or antidepressant therapy doesn’t really matter.
Dear colleagues, we had interesting studies this month. I think the most spectacular one was published in Science on long COVID. Thank you very much for listening and watching. I’m Christoph Diener from University Duisburg-Essen.
