A US study published in JAMA Network Open found that women are less likely than men to develop atrial fibrillation (AF) after open heart surgery. However, if women do experience postoperative AF, they face a higher long-term risk for mortality. The study analyzed over 21,000 patients who underwent heart surgery and found that women had a lower risk for postoperative AF compared to men, but a higher risk for mortality if they developed AF. Researchers suggest that women may have protective factors against AF but are more vulnerable to its long-term effects, emphasizing the need for tailored postoperative care for women after heart surgery.
