Introduction: There has been a significant body of international literature supporting the favorable role of diet and lifestyle interventions in improving outcomes in patients with atrial fibrillation (AF). US-based dietary studies are limited. We aimed to study the predictors for patients willing to consider diet changes so target populations can receive increased attention in regards to dietary education. Methods: We conducted a pilot telephone survey to discuss willingness to participate in guided dietary intervention in patients with AF at a tertiary care center. If the patients were willing to participate, the process would entail diet counseling via bi-weekly phone calls and monthly surveys to assess dietary compliance. There was no financial incentive offered for their participation. Chart review was done to collect patient characteristics. Zip code was used as a surrogate to determine income level based on census data. Results: We attempted to contact 409 patients of whom we were able to reach 162 (39%) patients. 59 patients (36%) were willing to consider diet modification (Group A) while the remainder patients declined (Group B). The average age for both groups was similar (69±8 and 68±9 years respectively). There were 38% and 47% women in groups A and B respectively (p=0.4) There was no difference in the BMI, type of atrial fibrillation, EF, history of hypertension, diabetes, CAD, CKD, anxiety or depression medication use. Social determinants such as marital status, insurance status was similar in both groups. The median income was $57,500 in the study population. The ratio of patients with income over this level was identical in Groups A and B (46 and 52% respectively, p =0.5)There were significantly higher proportion of Caucasian patients in Group A compared to Group B (p=0.02). Patients in Group A were on a lower number of medications compared to Group B (7.3±4 vs 9±4 respectively, p =0.03). Conclusions: Patient willingness is generally the first factor for successful implementation of lifestyle modifications. Determining the factors which drive this willingness or pose as barriers to lifestyle modification can assist in formulation of targeted intervention strategies.
