RESUMEN
Atrial fibrillation (AF) is a growing public health concern, the impact of which is frequently underestimated. It has a profound effect on the quality of life (QoL) which appears to be disproportionately lower in female patients compared to men. We aim to explore the factors contributing to sex-related disparities in the QoL of AF patients by conducting a systematic review using the PubMed electronic search database. We used the following combination of medical subject heading (MeSH) parameters: "atrial fibrillation" and "sex" and "quality of life" with specific inclusion and exclusion criteria. We identified 13 relevant studies published between 2010 and 2020 for our review. These studies evaluated sex-related differences in QoL scores, symptom burden, and AF-related complications originating across different continents in Asia, Europe, and North America. We found that female patients reported a reduced QoL as compared to men and they were more likely to be older with multiple co-morbidities at presentation. Women also reported more frequent and severe symptoms, potentially explained by the greater prevalence of anxiety and depression and thus enhancing symptom perception. Moreover, they were less likely to be managed by anti-arrhythmic medications and invasive rhythm control strategies such as catheter ablation. Female patients with AF experienced more severe strokes, but no sex disparities were found in AF-related cognitive decline. We determined that the more prominent contributory factors towards a lowered QoL in female AF patients appear to be secondary to a higher burden and perception of symptoms as well as under-utilization of invasive treatment modalities. However, further studies are warranted to confirm these findings.
