Catheter ablation of atrial fibrillation in patients with diabetes mellitus.



Diabetes mellitus (DM) is an independent risk factor for atrial fibrillation (AF). Few studies have compared clinical outcomes after catheter ablation between patients with and those without DM.


The purpose of this study was to compare AF ablation outcomes in patients with and those without DM.


We performed a retrospective analysis of 351 consecutive patients who underwent first-time AF ablation. Clinical outcomes included freedom from recurrent atrial arrhythmia, symptom burden (Mayo AF Symptom Inventory score), cardiovascular and all-cause hospitalizations, and periprocedural complications.


Patients with DM (n = 65) were older, had a higher body mass index, more persistent AF, more hypertension, and larger left atrial diameter (P <.05 for all). Median (Q1, Q3) total radiofrequency duration [64.0 (43.6, 81.4) minutes vs 54.3 (39.2, 76.4) minutes; P = .132] and periprocedural complications (P = .868) did not differ between patients with and those without DM. After a median follow-up of 29.5 months, arrhythmia recurrence was significantly higher in the DM group compared to the no-DM group after adjustment for baseline differences (adjusted hazard ratio [HR] 2.24; 95% confidence [CI] 1.42-3.55; P = .001). There was a nonsignificant trend toward higher AF recurrence with worse glycemic levels (HR 1.29; 95% CI 0.99-1.69; P = .064).


Although safety outcomes associated with AF ablation were similar between patients with and those without DM, arrhythmia-free survival was significantly lower among patients with DM. Poor glycemic control seems to an important risk factor for AF recurrence.

Assistant Professor of Medicine

I am a cardiac electrophysiologist specializing in the treatment of heart rhythm disorders and management of cardiac implantable electronic devices (CIEDs). My research utilizes signal processing of electrocardiographic data and novel analytic techniques to better phenotype patients and identify those for whom interventional electrophysiology procedures may be most beneficial. This includes predicting which patients with left bundle branch block may benefit from early cardiac resynchronization therapy or conduction system pacing. I also analyze population level data to identify patients at high risk for adverse sequelae of rhythm disorders who may benefit from early intervention.

Larry Ronald Jackson

Associate Professor of Medicine

Dr. Jackson is a physician-scientist with clinical expertise in adult clinical cardiac electrophysiology. His research focuses on identifying determinants of racial/ethnic differences in arrhythmia care and the development and implementation of patient-centered interventions aimed at facilitating shared decision-making in populations that have been systemically disadvantaged with abnormal heart rhythm conditions. Dr. Jackson has an advanced degree (MHSc) in clinical and qualitative research methodology and is a member of the Duke Clinical Research Institute. His research skills, obtained during his time at the Duke Clinical Research Institute Research Fellowship, include formal training in large database analysis, clinical trial operations, scientific writing, clinical trial adjudication and statistical analysis. Dr. Jackson’s research funding consists of two career development awards: 1) National Institute of Health/National Heart, Lung, and Blood Institute-K01 focused on racial and ethnic differences in oral anticoagulation use in patients with atrial fibrillation and 2) AHA career development award focused on analyzing racial and ethnic differences in the use of rhythm control strategies in patients with atrial fibrillation.  Dr. Jackson’s long-term, overarching goal as a physician-scientist is to decrease racial and ethnic disparities in arrhythmia care for patients with abnormal heart rhythm conditions.
