Systemic lupus erythematosus (SLE or lupus) is a clinically heterogeneous disease with a variety of clinical presentations, such as rash, fatigue and arthritis. About 1 to 10 per 100 000 personyears have been diagnosed with new-onset SLE, with prevalence rate ranging from 0.3 to 241 per 100 000. 1 People of all ages can be affected; many studies have proven that women, especially
Aim. We aimed to evaluate the effectiveness and safety between high-power short-duration (HPSD) radiofrequency ablation (RFA) and conventional RFA in patients with atrial fibrillation (AF). Methods. Studies comparing HPSD and traditional applications in patients undergoing initial catheter ablation for atrial fibrillation from inception through December 2021 were searched on Pubmed, Medline, Cochrane, and Clinicaltrials.gov. Results. The meta-analysis included seventeen studies with a total of 4934 patients. HPSD group decreased procedure duration (mean difference (MD) −38.28 min, P < 0.001 ), RF duration (MD −20.51 min, P < 0.001 ), fluoroscopy duration (MD −5.19 min, P < 0.001 ), and acute pulmonary vein reconnection (Odds ratio (OR) 0.40, P < 0.001 ), while improving the freedom from atrial arrhythmia at one year (OR 1.48, 95% confidence interval (CI) 1.12–1.94, P = 0.005 ) and rates of first-pass isolation (OR 8.92, P = 0.001 ). Compared with the conventional group, freedom from atrial arrhythmia at one-year follow-up was higher in the HPSD group without the guidance of AI/LSI (OR 1.66, P = 0.01 ) and studies with a power setting of 40–50 W (OR 1.93, P = 0.002 ). Nevertheless, the two groups had similar effectiveness with a power setting of 50 W in the HPSD RFA (OR 1.10, P = 0.52 ). There was no difference in complications between the two groups ( P = 0.71 ). Conclusion. HPSD RFA was associated with shorter procedure duration, higher freedom from atrial arrhythmia, and comparable safety compared to conventional RFA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
