Abstract
Introduction: The effect of T lymphocytes on atrial fibrillation (AF) is still unclear. We aimed to assess the associations between the T-lymphocyte subgroup distribution and incident AF and AF prognosis.
Methods: Consecutive patients were enrolled from June 2020 to October 2021. Their T-cell subgroups, including CD3, CD4, and CD8 T cells, and the CD4/CD8 ratio (CDR) were measured. We assessed the relationships between the CDR and composite endpoints, including hospitalization due to heart failure, stroke or systemic embolism, and cardiovascular mortality rates.
Results: A total of 45,905 patients, among whom 818 had AF, were enrolled. The proportions of the T-lymphocyte subgroups CD3 (OR: 0.9995; 95% CI: 0.9993-0.9997, p < 0.001), CD4 (OR: 0.9995; 95% CI: 0.9991-0.9998, p = 0.004), and CD8 (OR: 0.9988; 95% CI: 0.9984-0.9992, p < 0.001) and the CDR (OR: 1.2714; 95% CI: 1.1355-1.4165, p < 0.001) were correlated with AF incidence. The CDR was associated with AF incidence (OR: 1.1998; 95% CI: 1.0746-1.3336, p < 0.001) after adjustment. High CDR was associated with a higher rate of hospitalization due to heart failure (HR: 3.45; 95% CI: 1.71-6.96, p < 0.001), stroke, or systemic embolism (HR: 2.54; 95% CI: 1.32-4.91, p = 0.005), and cardiovascular mortality (HR: 2.25; 95% CI: 1.05-4.84, p = 0.038). There was no significant difference in all-cause mortality between CDR strata (HR: 1.61; 95% CI: 0.90-2.87, p = 0.111).
Conclusion: Elevated CDR was positively associated with the incidence and prognosis of AF. This finding may help improve the prevention and treatment of AF.
期刊介绍:
''Cardiology'' features first reports on original clinical, preclinical and fundamental research as well as ''Novel Insights from Clinical Experience'' and topical comprehensive reviews in selected areas of cardiovascular disease. ''Editorial Comments'' provide a critical but positive evaluation of a recent article. Papers not only describe but offer critical appraisals of new developments in non-invasive and invasive diagnostic methods and in pharmacologic, nutritional and mechanical/surgical therapies. Readers are thus kept informed of current strategies in the prevention, recognition and treatment of heart disease. Special sections in a variety of subspecialty areas reinforce the journal''s value as a complete record of recent progress for all cardiologists, internists, cardiac surgeons, clinical physiologists, pharmacologists and professionals in other areas of medicine interested in current activity in cardiovascular diseases.
