Clinically significant food preferences of patients with atrial fibrillation: a nosological and regional peculiarities

The aim of the investigation was to study the peculiarities of food consumption in patients with atrial fibrillation, capable of influencing the anticoagulant therapy with warfarin, in comparison with healthy volunteers and taking into account geographical specifics. Materials and methods. In an open cohort study, 196 respondents (88 men, 108 women) evaluated food preferences using a questionnaire survey. The quantitative evaluation of adherence to lifestyle modification was studied by QAA-25. Statistical data processing was performed by parametric (Student's t-test) and nonparametric (Wald-Wolfowitz, Kolmogorov-Smirnov, Pearson) analysis methods. Results. There were no statistically significant differences in food rations between the studied categories of respondents, both increasing [37.0±19.5 points versus 37.3±17.98 points; Wald-Wolfowitz (Z), p=0.16] and reducing the activity of warfarin [62.2±26.3 points versus 63.4±23.8 points; Wald-Wolfowitz (Z), p=0.95]. The absence of differences remained in the evaluation, taking into account regional characteristics of nutrition. The respondents were taking warfarin, there is no relationship between the level of commitment to the modification of lifestyle and diet modification. Conclusion: it is shown that medical recommendations aimed at correcting the eating behavior of respondents taking warfarin are not effective, which can be an independent risk factor for complications of both warfarin therapy and the underlying disease.
