“…In contrast, in the study done by Kohpayezadeh et al, there was no significant difference between the patients and subjects of control groups in terms of the consumption of vegetables and legumes [34]. In a metaanalysis done by McEvoy et al, there was no relationship between the consumption of vegetables and risk factors for cardiovascular disease in obese adults with a high risk of heart disease [38]. In this study, the consumption of garlic and onion decreased the severity of RCA and LAD coronary artery stenosis.…”

Background Coronary artery diseases (CAD) are one of the major causes of mortality, which is related to the nutritional status and anthropometric indices of individuals. The aim of this study was to determine the relationship between anthropometric indices, the type of protein consumption in meat group and vegetable consumption with coronary artery stenosis. Methods This descriptive and analytical cross-sectional study was conducted in Shariati Hospital in Tehran in 2016. Out of the patients undergoing coronary angiography, 208 cases were assigned to participate in the study of simple random sampling. The required data were collected by Food Frequency questionnaire (FFQ), anthropometric indices and physical activity questionnaire. SPSS software (version #21) was used for statistical analysis. Results The number of coronary arteries with more than 50% stenosis was increased by high consumption of red meat (P = 0.014), egg (P = 0.006) and chicken (P = 0.030) and low consumption of legume (P = 0.000), soybean (P = 0.002) and vegetables (P = 0.003). Also, the consumption of garlic and onion was associated with a decrease in the severity of stenosis in left anterior descending (LAD) (P = 0.036), and right coronary artery (RCA) (P = 0.033). There was a significant and positive correlation among waist circumference, wrist circumference and body mass index in patients with coronary artery stenosis and a negative correlation between the height of the patient and the history of previous angiography. Conclusion High consumption of vegetable proteins, vegetables, maintaining BMI and waist circumference in the normal range, were associated with reduced severity of coronary artery stenosis. In addition high consumption of red meat, chicken and egg is associated with higher severity and number of coronary stenosis.

“…The retinal microvasculature is the easiest and most widely used vascular bed that can be directly visualized in vivo and may provide a non-invasive, surrogate method to study early structural changes and pathological features of the human microcirculation ( 1 – 3 ). Over the past two decades, a computerized method of measuring the retinal vascular caliber using retinal photographs has been developed ( 4 ).…”

Dietary Vitamins A, C, and Potassium Intake Is Associated With Narrower Retinal Venular Caliber

IntroductionThe retinal vasculature, a surrogate for the systemic microvasculature, can be observed non-invasively, providing an opportunity to examine the effects of modifiable factors, such as nutrient intake, on microcirculation. We aimed to investigate the possible associations of dietary nutrient intake with the retinal vessel caliber.MethodsIn this cross-sectional study, a total of 584 participants in a medical survey of Japanese descendants living in Los Angeles in 2015 underwent a dietary assessment, fundus photographic examination, and comprehensive physical and blood examinations. Retinal vessel caliber was measured using fundus photographs with a semi-automated computer system and summarized as central retinal artery and vein equivalents (CRAE and CRVE). The association between dietary nutrient intake and retinal vessel caliber was analyzed using a multivariate linear regression model adjusted for two models including potential confounders. The first model was adjusted for age and sex. The second model was adjusted for age, sex, smoking status, body mass index, hypertension, diabetes, dyslipidemia, history of coronary heart disease, and history of stroke.ResultsAfter adjustment of potential confounders, compared to the quartile with the lowest intake, the difference in CRVE for the highest quartile was −5.33 μm [95% confidence interval (CI): −9.91 to −0.76, P for trend = 0.02] for vitamin A, −4.93 μm (95% CI: −9.54 to −0.32, P for trend = 0.02) for vitamin C and −3.90 μm (95% CI: −8.48 to 0.69, P for trend = 0.04) for potassium.ConclusionsA significant association was observed between higher vitamins A, C and potassium intakes and narrower retinal venular caliber.

“…According to the literature, vessel width related biomarkers like the central retinal arteriolar equivalent (CRAE), the central retinal venular equivalent (CRVE) and the arteriolarto-venular ratio (AVR) [10] are significantly associated with the progress of diabetes, hypertension and other cardiovascular diseases [8,9]. However, recent clinical studies on retinal vascular caliber changes still rely on a semi-automatic software: IVAN developed by University of Wisconsin, USA more than 20 years ago [3,11,12]. According to our experience, assessing the vessel calibers of one retinal image, with resolution 3456 × 2304, using IVAN takes around 7-10 min, including automatic vessel detection and classification, manual cropping, adding vessel segments and correcting their labels.…”
