A procedure to close the left atrial appendage is more effective than blood thinners in reducing the risk of stroke in atrial fibrillation. The research was published in the journal JACC: Clinical Electropsychology.
Atrial fibrillation (atrial fibrillation) is a heart rhythm disorder accompanied by a chaotic or very fast heartbeat. This condition significantly increases the risk of ischemic stroke, meaning a blood clot blocks an artery that carries blood to the brain. Endovascular closure of the left atrial appendage is also used to prevent stroke, as well as blood thinners. It isolates the area of the heart, where blood clots often form, from the rest of the blood flow. However, neither strategy provides 100% protection against stroke, and sudden ischemic stroke may occur.
Doctors at Mount Sinai Medical Center in New York analyzed data from patients who had their left atrial appendage closed (125 patients) or were treated with blood thinners (322 patients). All experienced a sudden stroke, but those taking the pill had a higher risk of disability (70.3% vs. 38.3%) or death (56.2% vs. 33.3%). The study suggests that turning off the left atrial appendage may be more effective in preventing severe sudden strokes in patients with atrial fibrillation.
