This letter addresses key limitations in the article "Trends and disparities in cardiovascular deaths in systemic lupus erythematosus: A population-based retrospective study in the United States from 1999 to 2020." While the article provides valuable insights into cardiovascular mortality among SLE patients, it overlooks critical factors such as medication adherence and sex-specific treatment responses, which could influence the reported outcomes. Additionally, the study's focus on cardiovascular deaths sidelines other relevant causes of mortality like infections and renal failure. Incorporating these considerations, along with a deeper exploration of socioeconomic disparities and healthcare infrastructure, could enhance future studies, offering a more comprehensive understanding of mortality trends in SLE patients.
