Association of Food and Alcohol Consumption with Peripheral Atherosclerotic Plaque Volume as Measured by 3D-Ultrasound.

Background: Food patterns and alcohol consumption influence the risk for cardiovascular diseases (CVD) and a healthy nutrition is essential for the prevention of CVD. The aim of this study was to determine the influence of nutrition and alcohol consumption on peripheral atherosclerotic plaque volume (PV) using an innovative 3D ultrasound approach. Methods: In this prospective, single centre study we included 342 patients with at least one cardiovascular risk factor or established CVD. PV in the carotid and femoral artery was measured using a semi-automatic software. Information on food and alcohol consumption of the participants was collected using an internationally acknowledged standardized questionnaire (DEGS1). Results: Patients with low total PV consumed significantly more vegetables (p = 0.004) and vegetable juice (p = 0.019) per week compared to patients with high total PV. In contrast, patients with high total PV reported a higher alcohol consumption compared to patients with low total PV (p = 0.026). Patients without vascular disease, in particular cerebrovascular disease (p = 0.001) and peripheral arterial disease (p = 0.012), reported a significantly higher fish consumption per week. In the multivariate model, we found a significant negative association for vegetable consumption (p = 0.034) and female gender (p = 0.018) but a significant positive association for alcohol (p = 0.001), age (p < 0.001) the presence of vascular disease (p < 0.001) and cardiovascular risk factors (p < 0.001) with total PV. Conclusion: In this study we were able to show an association of food and alcohol consumption with peripheral atherosclerotic PV measured by 3D-ultrasonography. Following a healthy nutritional lifestyle (vegetable consumption, no excessive alcohol consumption) and regular fish consumption appears to be associated with less peripheral atherosclerosis and decreased prevalence of vascular diseases, respectively.
