Attractive Versus Golden Ratios: Formula of Utopian Beauty through Comparison of Facial Proportions among Worldwide Celebrities and Average People.

INTRODUCTION: Beauty criteria change according to trends, cultures, and expectations. So, the golden ratios are not enough to understand the actual beauty concept. OBJECTIVE: It is aimed to create a method and formula to define beauty in terms of different facial measurements and ratios as variables. METHODS: Frontal view photographs of 50 celebrities and 50 volunteers (female [ n = 70] and male [ n = 30]) were obtained. Thirty-three specific facial points were used. Fifty-nine measurements of distances between those points and ratios of those distances are used as statistical variables. Mean values of those variables for celebrities are compared with all participants.Then, ''total beauty score'' using statically significant differences is defined. Points according to the importance level of interested value are assigned; 1 point for a significance of 0.001 ≤ P < 0.05 and 2 points for P < 0.001. Possible independent variables for the prediction of Utopian Beauty Score were determined using linear regression analysis. Finally, 10 variables (6 measurements and 4 ratios) are used to determine a formula for beauty. RESULTS: In celebrities, the distance between head apex and hair border, lower lip vertical length, the distance between brow medial borders and forehead vertical length were higher than the average population ( P < 0.001, 0.023, 0.034, 0.001, respectively). However, the width of columella, a length between bilateral ala nasi, horizontal face, and vertical nose length, and the distance between brow apexeyelash line were shorter ( P = 0.005, < 0.001, < 0.001, < 0.001, < 0.001, respectively). Some study variables had severely significant correlations with the total beauty point (M29, r = -0.744, P < 0.001; R19, r =-0.745, P < 0.001; and R30, r = -0.735, P < 0.001). The linear regression formula for Utopian Beauty Score was determined according to statistically significant variables as y = 86.5 - 3.6 M5 + 8.1 M14 + 11.1 M20 - 6.4 M25-8.7 M29-10.3 M30-15.6 R19 + 9.3 R20 + 16.4 R25 + 18.3 R26. CONCLUSIONS: A large forehead, small nose with lifted tip, plump lip, brows with lateral apex, well-spaced eyes, and ovoid, elliptical face lines are seem to be more attractive. Additionally, a method to create a formula for beauty with variables of different measurements and ratios of facial points are determined.

An echocardiographic predictor of contrast-induced nephropathy following percutaneous coronary intervention in acute coronary syndrome: aortic valve sclerosis.

Objective. Aortic valve sclerosis (AVS) is closely related to endothelial dysfunction. The association of AVS with contrast-induced nephropathy (CIN) is unknown. We planned to investigate the relationship of AVS besides known parameters with CIN. Design. Baseline characteristics, biochemical values, and AVS of 292 consecutive patients with acute coronary syndrome (ACS) that underwent percutaneous coronary intervention (PCI) were analyzed. Results. Fifty-three patients (18.2%) had CIN. Patients with CIN were older, less likely to be smokers, and had more prevalent prior bypass surgery, higher Mehran score, creatinine, and uric acid concentrations than those without CIN. AVS was more prevalent in patients with CIN. Logistic regression analysis including all related parameters identified Mehran score (OR = 1.036, p = .033), uric acid concentration (OR = 1.244, p = .023), and AVS (OR: 2.223, p = .027) as independent predictors of CIN. Conclusion. AVS is independently associated with CIN in patients with acute coronary syndrome undergoing percutaneous coronary intervention. AVS may help to identify high-risk patients for CIN, who would benefit from preventive measures.

Hair whitening and obesity are independently related to ascending aorta dilatation in young-middle aged men.

OBJECTIVE: Hair whitening (HW) is strongly linked with aging. Ascending aortic dilation (AAD) and HW share common etiologic factors. We investigated the association of HW with ascending aortic diameters. METHODS: Our study included 93 male subjects aged below 50 years. All patients underwent echocardiography to measure ascending aortic diameter, in addition to routine biochemistry tests, physical examination, and thorough medical history. HW score (HWS) was defined according to the percentage of white hair (HWS 1: <25%; HWS 2: 25-50%; HWS 3: 50-75%; and HWS 4: 75-100). RESULTS: Patients with highest HWS were older and had a higher percentage of hypertension (HT) and family history of HW. Moreover, this subgroup had increased ascending aortic diameter, higher serum uric acid, and lower total bilirubin concentrations. Multivariate analyses including age, HT, height, waist circumference, c-reactive protein, and family history of HW identified body weight and HWS as the independent predictors of ascending aortic diameter. CONCLUSION: An independent association between the degree of HW and AAD exists in middle-aged men, which may depend on coexisting factors that enhance both pathologies rather than causality. We think that oxidative stress may be one of these stressors.

An increase in epicardial adipose tissue is strongly associated with carotid-intima media thickness and atherosclerotic plaque, but LDL only with the plaque.

OBJECTIVE: Carotid intima-media thickness (CIMT) is reliable marker of subclinical atherosclerosis and cardiovascular events. Until today, there was no study that investigated whether epicardial adipose tissue (EAT), which is a surrogate for lipid depot in a special visceral tissue or circulating lipids, is more important for CIMT and atherosclerotic plaque. METHODS: Our study, having cross-sectional and prospective observational design, included 252 patients who were admitted to our outpatient clinic. EAT identified as an echo-free space under the pericardial layer on 2-dimensional echocardiography, was measured perpendicularly in front of the right ventricular free wall at end-systole. RESULTS: EAT significantly correlated with CIMT (r=0.623, p<0.001). CIMT was significantly increased with rising EAT thickness (0.72±0.15 mm, 0.85±0.16 mm, and 0.95±0.12 mm in patients with EAT <5 mm, 5-7, and >7 mm, p<0.001, respectively). Multiple linear regression analysis revealed that age (Beta: 0.406, p<0.001), male gender (Beta: 0.244, p<0.001), and EAT (Beta: 0.450, p<0.001) as independent correlates of CIMT. Otherwise, in logistic regression analysis, only EAT (OR, 1.386; 95% CI, 1.203-1.597, p<0.001) and LDL cholesterol (OR, 1.013; 95% CI, 1.002-1.013, p=0.02) were independent predictors for presence of carotid plaque. CONCLUSION: Our study showed that EAT has a relationship with both CIMT and the presence of carotid plaque, but LDL is independently related to the plaque. This finding suggests that EAT thickness may be a risk factor and biomarker, playing an important role beginning from early stages of atherosclerosis, unlike LDL cholesterol, which appear to have a role in later stages of atherosclerosis.

Epicardial Adipose Tissue Thickness Is an Independent Predictor of Critical and Complex Coronary Artery Disease by Gensini and Syntax Scores.

Epicardial adipose tissue thickness is associated with the severity and extent of atherosclerotic coronary artery disease. We prospectively investigated whether epicardial adipose tissue thickness is related to coronary artery disease extent and complexity as denoted by Gensini and Syntax scores, and whether the thickness predicts critical disease. After performing coronary angiography in 183 patients who had angina or acute myocardial infarction, we divided them into 3 groups: normal coronary arteries, noncritical disease (≥1 coronary lesion with <70% stenosis), and critical disease (≥1 coronary lesion with <70% stenosis). We used transthoracic echocardiography to measure epicardial adipose tissue thickness, then calculated Gensini and Syntax scores by reviewing the angiograms. Mean thicknesses were 4.3 ± 0.9, 5.2 ± 1.5, and 7.5 ± 1.9 mm in patients with normal coronary arteries, noncritical disease, and critical disease, respectively (P <0.001). At progressive thicknesses (<5, 5-7, and >7 mm), mean Gensini scores were 4.1 ± 5.5, 19.8 ± 15.6, and 64.9 ± 32.4, and mean Syntax scores were 4.7 ± 5.9, 16.6 ± 8.5, and 31.7 ± 8.7, respectively (both P <0.001). Thickness had strong and positive correlations with both scores (Gensini, r =0.82, P <0.001; and Syntax, r =0.825, P <0.001). The cutoff thickness value to predict critical disease was 5.75 mm (area under the curve, 0.875; 95% confidence interval, 0.825-0.926; P <0.001). Epicardial adipose tissue thickness is independently related to coronary artery disease extent and complexity as denoted by Gensini and Syntax scores, and it predicts critical coronary artery disease.

The relationship of plasma catestatin concentrations with metabolic and vascular parameters in untreated hypertensive patients: Influence on high-density lipoprotein cholesterol.

OBJECTIVE: Catestatin has several cardiovascular actions, in addition to diminished sympatho-adrenal flow. Decreased plasma catestatin levels may reflect a predisposition for the development of hypertension and metabolic disorders. We planned to investigate the possible roles of catestatin in untreated hypertensive patients. As a secondary objective, we compared catestatin concentrations of healthy subjects with those of hypertensive patients in order to understand whether catestatin is increased reactively or diminished at onset. METHODS: Our study was cross-sectional and observational. The patient group, comprising 109 consecutive untreated hypertensive patients without additional systemic or coronary heart disease, underwent evaluations of plasma catestatin, waist circumference, lipid parameters, left ventricular mass, carotid intima-media thickness, and flow-mediated dilation of the brachial artery. Additionally, we measured catestatin concentrations of 38 apparently healthy subjects without any disease using a commercial enzyme-linked immunosorbent assay kit. RESULTS: We documented increased catestatin concentrations in previously untreated hypertensive patients compared to healthy controls (2.27±0.83 vs. 1.92±0.49 ng/mL, p=0.004). However, this association became insignificant after adjustments for age, gender, height, and weight. Within the patient group, catestatin levels were significantly higher in females. Among all study parameters, age, high-density lipoprotein cholesterol (HDL-C) correlated positively to plasma catestatin, whereas triglycerides, hemoglobin, and left ventricular mass correlated negatively to plasma catestatin. We could not detect an association between vascular parameters and catestatin. Catestatin levels were significantly elevated with increasing HDL-C (1.91±0.37, 2.26±0.79, and 3.1±1.23 ng/mL in patients with HDL-C <40, 40-60, and >60 mg/dL, respectively). Multiple linear regression analysis revealed age (beta: 0.201, p=0.041) and HDL-C (beta: 0.390, p<0.001) as independent correlates of plasma catestatin concentration. Additionally, male gender (beta:-0.330, p=0.001) and plasma catestatin (beta: 0.299, p=0.002) were significantly associated with HDL-C concentrations. CONCLUSION: We documented that plasma catestatin is an independent predictor of high-density lipoprotein cholesterol. In addition to antihypertensive effects, catestatin appears to be related to improved lipid and metabolic profiles. Coexistence of low catestatin levels with low HDL-C may provide a probable mechanism for the predictive value of low HDL-C for increased hypertension and cardiovascular events.

Epicardial adipose tissue thickness is associated with myocardial infarction and impaired coronary perfusion.

OBJECTIVE: Epicardial adipose tissue (EAT) is associated with the presence, severity and extent of atherosclerotic coronary artery disease (CAD) in addition to subclinical atherosclerosis. We investigated if EAT thickness is related to acute myocardial infarction in patients with CAD. We also searched for the association between EAT thickness and objective coronary flow and myocardial perfusion parameters such as Thrombolysis in Myocardial Infarction Frame count (TFC) and myocardial blush grade (MBG). METHODS: Two-hundred consecutive patients with stable angina pectoris or acute coronary syndrome who were admitted to Ufuk University Faculty of Medicine, Dr Ridvan Ege Hospital cardiology department were included in this observational, cross-sectional study. EAT thickness was evaluated by conventional transthoracic echocardiography. Coronary angiography was performed to determine the coronary involvement and perfusion. RESULTS: Mean EAT thicknesses were 5.4±1.9 mm, 6.3±1.8 mm, and 8.5±1.4 mm in the stable angina pectoris (SAP), unstable angina pectoris (USAP) and acute myocardial infarction groups, respectively (p<0.001). With increasing EAT thickness, TFC increases whereas mean MBG values decrease (for EAT thickness <5 mm, 5-7 mm, >7 mm; mean TFC: 21.6±2.2, 25.3±3.3 and 35.2±7.7; and MBG values: 2.98±0.14, 2.83±0.57 and 1.7±1.16, respectively; both p<0.001). Cut-off EAT value to predict AMI was identified as 7.8 mm (ROC analysis AUC:0.876; p<0.001, 95% CI:0.822-0.927). Sensitivity and specificity of EAT cut-off value 7.8 mm to predict AMI were 81.8% and 82.5% respectively. CONCLUSION: Increased EAT is associated with AMI and it may prove beneficial for choosing patients who would need more aggressive approach in terms of risk reduction using echocardiography which is a relatively cheap and readily available tool as a follow-up parameter.

Bilirubin Level is Associated with Left Ventricular Hypertrophy Independent of Blood Pressure in Previously Untreated Hypertensive Patients.

BACKGROUND AND OBJECTIVES: Left ventricular hypertrophy (LVH), a sign of subclinical cardiovascular disease, is an important predictor of cardiovascular morbidity and mortality. The aim of our study was to determine the association of left ventricular mass (LVM) with possible causative anthropometric and biochemical parameters as well as carotid intima-media thickness (CIMT) and brachial flow-mediated dilation (FMD) as surrogates of atherosclerosis and endothelial dysfunction, respectively, in previously untreated hypertensive patients. SUBJECTS AND METHODS: Our study included 114 consecutive previously untreated hypertensive patients who underwent echocardiography and ultrasonography to evaluate their vascular status and function via brachial artery CIMT and FMD. RESULTS: Among all study parameters, age, systolic blood pressure (BP), diastolic BP, pulse pressure, plasma glucose, uric acid, total bilirubin, direct bilirubin, hemoglobin, and CIMT were positively correlated with the LVM index. Multiple logistic regression analysis revealed that office systolic BP, age, male gender, and total bilirubin were independent predictors of LVH. CONCLUSION: Bilirubin seems to be related to LVM and LVH. The positive association of bilirubin with these parameters is novel and requires further research.

The effect of irritable bowel syndrome on carotid intima-media thickness, pulse wave velocity, and heart rate variability.

OBJECTIVE: Irritable bowel syndrome (IBS), a subgroup of functional somatic disorders, may be associated with autonomic dysfunction (AD). Heart rate variability (HRV), a measure of autonomic dysfunction, may predict survival. The aim of this study was to investigate the effect of IBS on HRV parameters, carotid intima-media thickness (CIMT) and carotid-femoral pulse wave velocity (cf-PWV) as surrogates of AD, subclinical atherosclerosis and arterial stiffness, respectively. METHODS: Our study was cross-sectional and observational. Thirty consecutive patients with IBS and 30 control participants underwent 24-hour Holter monitoring, cf-PWV assessment and CIMT measurement. The diagnosis of IBS was based on Rome III criteria. There were 24 patients with IBS-Constipation (80%), 4 patients with IBS-Diarrhea (13.3%), and 2 patients with IBS-Mixed (6.7%) in IBS group. Student t-test and χ2 test were utilized in order to compare continuous and categorical variables between two groups, respectively. RESULTS: Biochemical parameters did not differ between groups except for slightly increased creatinine in patients with IBS. cf-PWV and CIMT values were similar between groups. SDNN index and RMSSD were significantly impaired in patients with IBS compared to controls. Frequency analyses revealed lower LF, HF, and VLF in subjects with IBS. CONCLUSION: We demonstrated decreased parasympathetic modulation in patients with constipation predominant IBS. However, we could not demonstrate any changes in vascular structure and functions measured by carotid intima-media thickness and pulse wave velocity. Our results do not support accelerated atherosclerosis in IBS population.

Comparison of radiation-induced damage between CT angiography and conventional coronary angiography.

OBJECTIVE: Both computed tomography (CTA) and conventional angiography (CCA) can provide direct visualization of the coronary arteries. The aim of the present study was to compare the radiation exposure between CTA and CCA and to search whether this amount of radiation causes significant DNA damage. METHOD: Seventy-two patients who underwent CTA or CCA were enrolled prospectively. We recorded the radiation dosage that was used during the procedures and calculated the effective dose (ED). We determined the sister chromatid exchange (SCE) level from the blood samples which were drawn from the patients before and after the procedures. The change in SCE is used as the measure of DNA damage induced by the radiation. RESULTS: The patients in the CTA (n = 36) and CCA groups (n= 36) had similar baseline characteristics. The ED was higher in CTA examinations compared to CCA examinations (14.2 +/- 2.7 vs 6.4 +/- 3.1, P <0.001). The SCE level increased significantly after both angiography methods (P <0.001). When the change in SCE after angiography was compared, we did not find a significant difference among the groups (2.73 +/- 1.6 vs 2.54 +/- 1.22, P= NS). CONCLUSION: Although the patients who underwent CTA were exposed to a greater amount of radiation, the radiation-induced genetic damage was similar with both types of the procedures.

Increased YKL-40 levels in patients with isolated coronary artery ectasia: an observational study.

OBJECTIVE: YKL-40, a new biomarker of localized inflammation, is secreted by macrophages within the atherosclerotic plaques. Coronary artery ectasia (CAE) is a clinical entity with unclear etiopathogenesis. Some studies have revealed that CAE may be a form of atherosclerosis that has more localized and intense inflammatory properties than atherosclerosis. The goal of this study was to investigate YKL-40 and C-reactive protein (CRP) levels in patients with isolated CAE compared to patients with normal coronary arteries (NCA) and coronary artery disease (CAD). METHODS: Our study has an observational and cross-sectional design. Forty-nine patients with isolated CAE (mean age: 60±10 years), 30 age-and gender-matched control participants with NCA (30 patients, mean age: 58±12 years) and 30 patients with CAD (mean age: 61±10 years), were included in the study. The relationship between YKL-40, CRP levels and the presence of CAE was investigated. Univariate and multiple logistic regression analysis were used for analysis of independent variables to predict CAE. RESULTS: Serum YKL-40 levels were significantly different among study groups (NCA: 110±53 µg/L, CAE: 144±68 and CAD: 180±117, p=0.005). CAD group and CAE group had significantly higher YKL-40 levels than NCA group (p=0.004 and p=0.015, respectively). CRP was not significantly different between three groups. In addition, there were no any statistically significant differences, with respect to age, gender, the presence of hypertension or diabetes mellitus, and the smoking status (p>0.05). Logistic regression analysis revealed only YKL-40 level as the determinant of CAE (OR: 1.010, 95% CI: 1.001-1.019, p=0.027). CONCLUSION: YKL-40 levels in patients with isolated CAE compared to patients with NCA were found significantly high and only YKL-40 level was established as the determinant of CAE. We believe that further studies are needed to clarify the possible causative roles of YKL-40 in patients with isolated CAE.

Increased pulse wave velocity and carotid intima-media thickness in patients with ulcerative colitis.

BACKGROUND: Ulcerative colitis (UC) is characterized with chronic, progressive inflammation of the gastrointestinal tract. The association of UC with cardiovascular disease is still a matter of debate. AIM: The aim of this study was to investigate whether carotid intima-media thickness (CIMT) and carotid-femoral pulse wave velocity (cf-PWV) as surrogates of atherosclerosis and arterial stiffness are increased in patients with UC. METHODS: Our study was cross-sectional and observational in design. Baseline characteristics were recorded during interview with the patient. Patients with previous cardiovascular disease, rheumatoid arthritis, chronic renal failure, and infectious and inflammatory disorders other than UC were excluded. Thirty-seven consecutive patients with UC and 30 control participants underwent cf-PWV assessment and CIMT measurement. The diagnosis of UC was based on clinical, radiologic, endoscopic, and histological findings. RESULTS: CIMT, cf-PWV, and C reactive protein were significantly higher in patients with UC. Although linear regression analyses identified UC as an independent predictor of CIMT (ß ± SE, 0.39 ± 0.08; p < 0.001), only age independently predicted cf-PWV (ß ± SE, 0.08 ± 0.03; p = 0.003) in our study population. Moreover, we revealed higher CIMT and PWV values in patients with higher disease activity and more extensive involvement, compared to patients with mild activity and limited disease. CONCLUSION: We revealed increased pulse wave velocity and CIMT in patients with UC. UC appears to be associated with arterial stiffness and atherosclerotic burden, but the underlying mechanisms require further studies to be identified.
