RESUMEN
BACKGROUND: Catheter ablation has obtained class 1 indication in ablation of young, healthy patients with symptomatic paroxysmal atrial fibrillation (AF). Anti-arrhythmic drugs (AADs) remain first-line therapy before ablating persistent AF (PersAF). We sought to evaluate the efficacy of a direct-to-catheter ablation approach against catheter ablation post AADs in PersAF. METHODS: In this DECAAF II subanalysis, patients were stratified into two subgroups: 'Direct-to-catheter' group comprising patients who had not received AADs prior to ablation, and'second-line ablation' group, comprising patients who had been on any AAD therapy at any time before ablation. Patients were followed over 18 months. The primary outcome was AF recurrence. Secondary outcomes included AF burden, quality of life (QoL) that assessed by the AFSS and SF-36 scores, and changes in the left atrial volume index (LAVI) assessed by LGE-MRI scans. RESULTS: The analysis included 815 patients, with 279 classified as'direct-to-catheter' group and 536 classified as'Second-line ablation' group. The primary outcome was similar between both groups (44.8% vs 44.4%, p > 0.05), as was AF burden (20% vs 16%, p > 0.05). Early remodeling, reflected by LAVI reduction, was similar between the groups (9.1 [1.6-18.0] in the second-line ablation group and 9.5 [2.5-19.7] in the direct-to-catheter group, p > 0.05). QoL pre/post ablation was also similar (p > 0.05). On multivariate analysis, history of AAD was not predictive of AF recurrence(p > 0.05). CONCLUSION: Prior AAD therapy demonstrated minimal impact on atrial remodeling and QoL improvement, in addition to limited benefit on AF recurrence and burden post-ablation in patients with PersAF. Additional studies are warranted to explore the efficacy of catheter ablation as a first-line therapy in PersAF.
RESUMEN
BACKGROUND: Catheter ablation is recognized as an effective treatment for atrial fibrillation (AF). Despite its effectiveness, significant sex-specific differences have been observed, which influence the outcomes of the procedure. This study explores these differences in a cohort of patients with persistent AF. We aim to assess sex differences in baseline characteristics, symptoms, quality of life, imaging findings, and response to catheter ablation in patients with persistent AF. METHODS: This post hoc analysis of the DECAAF II trial evaluated 815 patients (161 females, 646 males). Between July 2016 and January 2020, participants were enrolled and randomly assigned to receive either personalized ablation targeting left atrial (LA) fibrosis using DE-MRI in conjunction with pulmonary vein isolation (PVI) or PVI alone. In this analysis, we aimed to compare female and male patients in the full cohort in terms of demographics, risk factors, medications, and outcomes such as AF recurrence, AF burden, LA volume reduction assessed by LGE-MRI before and 3 months after ablation, quality of life assessed by the SF-36 score, and safety outcomes. Statistical methods included t-tests, chi-square, and multivariable Cox regression. RESULTS: Females were generally older with more comorbidities and experienced higher rates of arrhythmia recurrence post-ablation (53.3% vs. 40.2%, p < 0.01). Females also showed a higher AF burden (21% vs. 16%, p < 0.01) and a smaller reduction in left atrial volume indexed to body surface area post-ablation compared to male patients (8.36 (9.94) vs 11.35 (13.12), p-value 0.019). Quality of life scores were significantly worse in females both pre- and post-ablation (54 vs. 66 pre-ablation; 69 vs. 81 post-ablation, both p < 0.01), despite similar improvements across sexes. Safety outcomes and procedural parameters were similar between male and female patients. CONCLUSION: The study highlights significant differences in the outcomes of catheter ablation of persistent AF between sexes, with female patients showing worse quality of life, higher recurrence of AF and AF burden after ablation, and worse LA remodeling.
RESUMEN
The purpose of the current study was to determine the prevalence of depression and anxiety and their associated factors among Jordanian adolescents (n = 1,878) and Syrian adolescent refugees (n = 1,773) aged 12 to 17 years. The Center for Epidemiologic Studies-Depression Scale for Children (CES-DC), Patient Health Questionnaire-9-Modified, and Generalized Anxiety Disorder-7 questionnaire were used in this study. Approximately 27.2% of Jordanian adolescents and 28.3% of Syrian adolescent refugees had depression as assessed by the CES-DC. Among males, 17.6% of Jordanian adolescents and 19% of Syrian adolescent refugees had anxiety. Among females, 28.1% of Jordanian adolescents and 27.3% of Syrian adolescent refugees had anxiety. Overall, Jordanian adolescents and Syrian adolescent refugees had high prevalence of depression and anxiety. Establishing community-based mental health care in Jordan is crucial.
