RESUMEN
Background: Even though nutrition was demonstrated to have an impact on chronic atherosclerotic disease, there is a paucity of corresponding recommendations for patients with peripheral artery disease (PAD). A Mediterranean Diet based on daily intake of fruits and vegetables with high fibre, vegetable oil, and unsalted nuts including fish several times a week may have protective effects. This cross-sectional survey aimed to determine nutritional patterns amongst inpatients with PAD. Methods: All inpatients with symptomatic PAD who underwent revascularisation at a single centre between 1st May 2018 and 31st December 2021 were asked to fill out a questionnaire on nutritional intake. An 8-item frequency rating scale (from never to three times a day) was used for 15 food groups. For 11 of them, an adapted Mediterranean Diet score was calculated using the answers. The descriptive results were stratified by sex and disease stage (intermittent claudication vs. chronic limb-threatening ischaemia). Results: A total of 319 patients (31.7% female, 69.4 years in mean) were included. Thereof, 71.8% reported they did never receive any nutritional information considering their PAD disease. The mean adapted Mediterranean Diet score was 2.7 points (of maximum 11) with most patients not achieving the recommended servings per week for fruits (1.6%), vegetables (1.0%), and unsalted nuts (12.2%). The intake of cereals was sufficient (43.3%). When compared with men, women consumed more fruits and less meat. Conclusions: This survey demonstrated that although healthy nutrition may have a positive impact on patients with PAD, the education and adherence to a Mediterranean Diet was inappropriate. Nutritional patterns should be more focused in future PAD studies to derive specific recommendations and nutritional programmes as well as patient education in clinical practice.

BACKGROUND & AIMS: This systematic review sought to identify and summarize existing evidence for the impact of nutrition on the development, progression, and outcomes of peripheral artery disease (PAD). METHODS: We performed a systematic literature search of available studies published between January 1974 and December 2019. Randomized controlled trials (RCT), observational studies, and cross-sectional studies reporting either the primary or secondary prevention of PAD with nutritional intake were included. The quality assessment was performed for the RCTs, without pooling a meta-risk estimate. RESULTS: Among a total of 8502 records screened, 186 full texts were assessed for eligibility, and 82 studies (30% RCT) were analyzed. The nutrients were structured in fruits, vegetables and antioxidants, fats and oils, dietary fiber, meat, proteins, vitamins and trace elements, and diets and lifestyle. The findings of the current systematic review indicate that the Mediterranean diet, nuts, and polyunsaturated fat are associated with a lower incidence of PAD and saturated fat, cholesterol, and processed meat were associated with higher rates of cardiovascular events in patients suffering from PAD. CONCLUSIONS: The current review found evidence of a beneficial impact of the Mediterranean diet including nuts in this target population. More RCTs and high-quality registries are needed that focus on nutritional habits among patients with PAD to design appropriate preventive programs.
