Introduction: Diabetes mellitus is a well-known risk factor for cardiovascular disease, because of the accelerated process of atherosclerosis. Obesity is an established risk factor and has gained immense importance in recent studies as an important risk factor for clinical cardiovascular disease, yet the fundamental component stays unclear. Calf circumference is another form for lean mass and peripheral subcutaneous fat and is inversely associated with occurrence of carotid plaques (CP). Multiplicative and opposite effects of both Calf Circumference (CC) and Waist Circumference (WC) in event of CP suggest that the two measures should be taken into account commonly while assessing vascular risk profile. Aim & Objective: To ascertain if waist to calf circumference ratio (WCR) is a marker of Carotid atherosclerosis in patients with type 2 diabetes mellitus. To asses s the correlation between waist to calf circumference ratio and carotid intima media thickness (CIMT ) in patients with Type 2 diabetes. Materials and methods: A cross sectional study at Hospital affiliated to Kasturba Medical college Mangalore from Sept 2016 to Sept 2018 . Method of study: Patients with type 2 DM as per ADA criteria, age >18years are recruited for the study. Results and discussion: In our study with 150 population 25 patients had carotid atherosclerosis and 20 patients had CIMT>1.1. The waist circumference in patients with CA is in the range of 93.07 and 99.85 & the CC in patients with CA is in the range of 29.49 to 31.25. The WCR in patients with CA is in the range of 3.12 to 3.26. The difference was statistically significant with a p value of <0.05. In our study it was found that WC and WCR correlated well with carotid atherosclerosis, and surprisingly calf circumference also correlated with carotid atherosclerosis but not as significant as both WC and WCR. Conclusion: To conclude, in our population based study of 150 subjects we found that carotid atherosclerosis is significantly more in people with increased waist calf circumference ratio. WCR may be a new, useful and practical anthropometric index that facilitates the early identification of diabetic subjects with high risk for cardiovascular disease. Validation of this finding in individual populations is required. Future studies should test the association of calf circumference with carotid intima media thickness and carotid plaques using better measures than ultrasound such as magnetic resonance imaging. Further research focusing on underlying mechanisms in the role of lean mass and peripheral fat mass is required.

Abstract Carotid atherosclerosis has emerged as an early predictor of reduced cognitive function. Underlying this association are risk factors, such as overweight and obesity, that promote carotid atherosclerosis and poor cognitive outcomes. Given the prevalence of overweight and obesity among older adults, there is a critical need to better understand how atherosclerosis influences cognitive function in the context of elevated weight. To address this gap, the current study examined relations between carotid atherosclerosis (carotid intima-media thickness [IMT]), and attention (Trailmaking Test) and executive function (Verbal Fluency Test) performance, and whether they varied as a function of weight status (body mass index [BMI] classification). Data were analyzed from 162 older adults (mean age = 68.43y, 34% male, 41% African American), free of major disease. Mutliple regression and analysis of variance analyses, adjusted for age, sex, education and mean arterial pressure, showed a statistically significant IMT x BMI interaction for Verbal Fluency performance (p=.04) and a trending IMT x BMI interaction for Trailmaking A performance (p=.05). Simple effects analysis of IMT and Verbal Fluency performance showed that this association was most pronounced among those who are obese. Findings suggest atherosclerosis may influence executive function in the context of obesity among older adults. As the development of carotid atherosclerosis is strongly related to aging, our findings suggest that maintaining a healthy weight may reduce its impact on executive function in older adulthood.

Background:We tested the hypothesis that higher levels of cardiorespiratory fitness are inversely associated with carotid artery intima media thickness in 746 (age 53 ± 7 yrs) men with type 2 diabetes.Methods:We measured common carotid intima media thickness and defined carotid atherosclerosis as a carotid intima media thickness > 1.0 mm. Cardiorespiratory fitness was directly measured by peak oxygen uptake using expired gases analysis during a standard treadmill test.Results:Cardiorespiratory fitness was independently associated with common carotid intima media thickness in multivariable regression (β = –0.15, P < .05). After adjusting for established risk factors, high and moderate cardiorespiratory fitness were associated with lower odds ratios for having carotid atherosclerosis—0.49 (95% CI, 0.30–0.81), and 0.59 (95% CI, 0.38–0.92), respectively—as compared with low cardiorespiratory fitness. Each 1 metabolic equivalent increment higher cardiorespiratory fitness was associated with 27% (OR = 0.73; 95% CI, 0.61–0.87) lower prevalence of carotid atherosclerosis.Conclusions:These results suggest that high cardiorespiratory fitness is inversely associated with common carotid intima media thickness in men with type 2 diabetes.

Previous studies have suggested that kidney stone formers are associated with a higher risk of cardiovascular events. To our knowledge, there have been no previous examinations of the relationship between carotid intima-media thickness (IMT) and urinary stone risk factors. This study was aimed toward an investigation of the association between dyslipidemia, IMT, and 24-hour urinalysis in patients with calcium oxalate (CaOx) or calcium phosphate (CaP) stones. We prospectively enrolled 114 patients with kidney stones and 33 controls between January 2016 and August 2016. All patients were divided into four groups, according to the stone compositions—CaOx ≥ 50% group, CaP group, struvite group, and uric acid stones group. Carotid IMT and the carotid score (CS) were evaluated using extracranial carotid artery doppler ultrasonography. The results of a multivariate analysis indicated that a higher serum total cholesterol (TC) and low-density lipoprotein (LDL) were all associated with lower urinary citrate and higher CS in both the CaOx ≥ 50% and CaP groups. Higher serum TC and LDL were also associated with increased serum 8-OHdG levels in both groups. The levels of carotid IMT and CS in the CaOx ≥ 50% and CaP groups were all significantly higher than in the controls. These findings suggest a strong link between dyslipidemia, carotid atherosclerosis, and calcium kidney stone disease.

Background The association between elevated serum uric acid (SUA), cardiovascular disease (CVD) risk, and carotid atherosclerosis has long been explored, and contrasting results have been reported. Therefore, the role of SUA as an independent risk factor for vascular events (VEs) and carotid atherosclerosis deserves further attention. We investigated the relationship between SUA, incident VEs, carotid intima‐media thickness (cIMT), and cIMT progression in subjects at moderate‐to‐high CVD risk. Methods and Results In the IMPROVE (IMT‐Progression as Predictors of VEs) study, 3686 participants (median age 64 years; 48% men) with ≥ 3 vascular risk factors, free from VEs at baseline, were grouped according to SUA quartiles (division points: 244–284–328 µmol/L in women, 295–336–385 µmol/L in men). Carotid‐IMT and its 15‐month progression, along with incident VEs, were recorded. A U‐shaped association between SUA and VEs was observed in men, with 2.4‐fold ( P = 0.004) and 2.5‐fold ( P = 0.002) increased CVD risk in the first and fourth SUA quartiles as compared with the second. Adjusted hazard ratios (HRs) for cerebro‐VEs in men were the highest (first and fourth quartile versus second: HR, 5.3, P = 0.010 and HR, 4.4, P = 0.023, respectively). SUA level was independently associated with cIMT progression in men (β = 0.068, P = 0.014). No significant association between SUA levels, CVD end points, and cIMT progression were found in women. Conclusions Both low and high SUA levels are associated with an increased risk of VEs in men at moderate‐to‐high CVD risk but not in women. Only elevated SUA levels predict cIMT progression and at a lesser but not significant extent in women.
