Abstract Background Although the pathophysiology of coronary slow flow (CSF) has not been fully elucidated, emerging data increasingly support potential role for subclinical diffuse atherosclerosis in the etiology of CSF. We aimed to investigate relationship between atherogenic indices and CSF. Methods 130 patients with CSF diagnosed according to Thrombolysis in Myocardial Infarction (TIMI)-frame count (TFC) method and 130 controls who had normal coronary flow (NCF) were included in this retrospective study. Atherogenic indices (atherogenic index of plasma [AIP], Castelli risk indices I and II [CRI-I and II]) were calculated using conventional lipid parameters Results The logistic regression analyses demonstrated that AIP (OR, 5.463; 95% confidence interval [CI], 1.357–21.991; p = 0.017) and CRI-II (OR, 1.624; 95% CI, 1.138–2.319; p = 0.008) were independent predictors of CSF. Receiver operating characteristic analysis showed that the optimal cutoff value to predict the occurrence of CSF was 0.66 for AIP (sensitivity, 59%; specificity, 73%; area under curve [AUC], 0.695; p < 0.001) and 3.27 for CRI-II (sensitivity, 60%; specificity, 79%; AUC, 0.726; p < 0.001). Conclusions AIP and CRI-II levels were independent predictors of CSF, suggesting that atherogenic dyslipidemia may contribute to the pathophysiology of CSF.

Background: It has been reported that coronary slow flow (CSF) is associated with acute myocardial infarction, ventricular tachycardia, ventricular fibrillation, and even sudden cardiac death. Although studies concerning the etiopathogenesis of CSF are scarce, diffuse atherosclerosis and endothelial dysfunction are thought to play important roles. It has been suggested that a high plasma thrombomodulin (TM) level seems to play an important role in the pathogenesis of atherosclerosis and endothelial dysfunction. Objectives: We hypothesized that a high plasma TM level might be associated with CSF and aimed to research the relationship between plasma TM level and CSF. Methods: Fifty-two CSF patients with angiographically proven CSF and 44 cases with normal coronary flow were included in this study. Coronary flow velocity was determined by the thrombolysis in myocardial infarction (TIMI) frame count method. Plasma TM levels were measured in all the study subjects. Results: Plasma TM levels were significantly higher in the CSF group compared to the control group (3.9 ± 0.5 vs. 3.6 ± 0.3 ng/mL, p = 0.01). There was a positive relationship (r = 0.31, p = 0.002) between plasma TM level and mean TIMI frame count (TFC). Factors associated with mean TFC were plasma TM level (β = 0.206, p = 0.038) and red cell distribution width (β = 0.088, p = 0.009) in multiple linear regression analysis. Conclusions: Patients with CSF have a higher plasma TM level, and this may play an important role in the pathogenesis of CSF. An elevated plasma TM level may be a predictor of CSF. Future studies are needed to confirm these results.

Background: Aim was to study the influence of Thyroid hormones on lipid indices in obese individuals. Thyroid dysfunction is a common occurence in South India. Increased accumulation of fats is a common feature of obesity and hypothyroidism.Methods: The study was undertaken at GGH, Guntur and 150 Obese individuals with BMI of >30 were recruited. They are classified into 3 groups based on thyroid profile - Euthyroid (N=77), hypothyroid (N=45)and hyperthyroid (N=28). Their fasting venous blood samples were analysed for thyroid profile, lipid profile, FBS and creatinine. Anthropometric data like height, weight and abdominal circumference was recorded. Lipid indices, atherogenic index of plasma (AIP), Castelli’s Risk Index (CRI) 1 and 2, small dense LDL (sdLDL), Atherogenic coefficient (AC) and BMI were calculated.Results: All the 3 groups showed female preponderance. In hypothyroid cases TSH, T3 and T4 showed significant correlation with lipid parameters (p value<0.0001) and with lipid ratios TSH and T4 significantly elevated (p value <0.00001). There was significant correlation of TSH with TC, TG and LDL between hypothyroid, hyperthyroid and euthyroid cases(p<0.0001). Spearman’s Rho correlation analysis showed negative correlation of Lipid ratios with T3, T4 and TSH in all 3 groups.(r≤1.0). Whereas multiple regression analysis of lipid ratios in all 3 groups with TSH as dependent variable demonstrated positive relation with sdLDL (p<0.01).Conclusions: Assessment of thyroid function is mandatory in all obese individuals to predict complications especially cardiovascular disease.

Background/Aim. Cardiovascular morbidity and mortality are markedly increased in chronic renal failure (CRF). The aim of this study was to evaluate lipid parameters and bioindices in patients with different stages of CRF. Methods. In 46 hemodialysed (HD), 50 CRF patients with II, III and IV stage of CRF (non-HD) and 48 control subjects triglycerides (TG), total cholesterol (C), HDL-C, urea, creatinine, creatinuria (standard biochemical methods), apolipoprotein (apo) AI, apo B, lipoprotein(a), cystatin C (immunoturbidimetric method) were evaluated, and LDL-C, non-HDL-C, LDLC/ HDL-C, non-HDL-/HDL-C, TG/HDL-C, and new bioindices, LTI (lipid tetrad index), logLTI, LPI (lipid pentad index), logLPI, AIP (atherogenic index of plasma), and creatinine clearance were calculated. Results. There were significant differences in the levels of TG, HDL-C, LDL-C, non- HDL-C, total C and apo A-I between the HD and non-HD patients, and the HD patients and the controls. LTI and LPI were significantly higher in the HD and non-HD patients compared to the controls (p < 0.05), without a good separation by the Box-Whisker plots. The values of TG/HDL-C ratio and AIP were significantly higher in the HD and non- HD-patients compared to the controls (p < 0.05), and significantly higher in the HD compared to non-HD patients (p < 0.05). AIP > 0.11 was found in 71.7% of the HD, 56% of non-HD and 31.3% of the controls. Conclusion. Among lipid parameters and indices, AIP and TG/HDL-C ratio are most suitable for evaluation of lipid disturbances in different stages of CRF. In addition to, non-HDL-/HDL-C, and apoB/A-I ratios, apo A-I, HDL-C and TG are important markers in HD patients. Non-HDL-C is not a suitable marker. LTI and LPI need to be further investigated.

Insulin resistance associated with dyslipidemia enhances cardiovascular risk. Several atherogenic indexes have been suggested to give more precise information about the risk. The aim of our study was to estimate, which atherogenic index correlates better with parameters of insulin resistance. Furthermore, we compared the parameters of lipid metabolism and insulin resistance between smokers and non-smokers. In our cross-sectional study we enrolled 729 patients with dyslipidemia which were divided into two groups – non-smokers (586) and smokers (143). We measured lipid profile, parameters of insulin resistance (fasting glycemia, insulin, HOMA-IR, C-peptide, proinsulin) and calculated atherogenic indexes – atherogenic index of plasma (log (TAG/HDL-C), AIP), ApoB/ApoA1 index and nonHDL-C. AIP was found out to show stronger correlations with parameters of insulin resistance (p<0.001, correlation coefficients ranging between 0.457 and 0.243) than other indexes (ApoB/ApoA1 or nonHDL cholesterol). AIP correlated with parameters of insulin resistance both in smokers and non-smokers, but after adjustment (for age, body mass index, waist circumference) persisting only in non-smokers. Smokers had a wider waist circumference and a proatherogenic lipid profile. Smoking increases the risk of developing metabolic syndrome. AIP can be used in daily praxis for predicting insulin resistance in patients with dyslipidemia, predominantly in non-smokers.

Introduction: Human obesity is strongly associated with cardiovascular disease. Cystatin C is a naturally occurring protease inhibitor and marker of cardiovascular disease. The atherogenic indices are used as an index for cardiac risk stratification. Objectives: To estimate the serum levels of Cystatin C in individuals with normal BMI, and obese, aged between 20-39 Yrs and to compare the levels of Cystatin C among these individuals and to correlate the levels of serum Cystatin C with atherogenic index of plasma and other indices. Methodology: The study population was taken from healthy volunteers of Mysore city, aged between 20-39 years of either sex. The study population was divided into 2 groups based on BMI. Each group contains sample size of 60. Fasting serum sample was analyzed for Total Cholesterol, TG, LDL-Cholesterol and HDL cholesterol by enzymatic method and serum Cystatin-C by immune-turbidimetric method using auto-analyser. Statistical Analysis: Analysis of Variance [ANOVA] was used to compare the serum levels of Cystatin C in the two groups. To correlate the serum Cystatin C with atherogenic indices for predicting the cardiovascular risk factors, Pearson’s correlation co-efficient was worked out. Results: The mean serum cystatin C levels in normal BMI group are 0.7±0.03 mg/L, and in Obese group 1.15±0.09 mg/(p value less than 0.001).In the study serum Cystatin C showed a positive correlation with serum triglycerides (r=0.7), Atherogenic index of plasma(AIP ) (r=0.80), TCHOL: HDL (Castelli’s Risk Index I) (r=0.71), HDL: LDL(Castelli’s Risk Index II) (r=0.70) respectively and Atherogenic coefficient (AC) {(NonHDLc)/HDLc}( r=0.60) and negative correlation with serum HDL(r=-0.52) Conclusion: Several indices had been derived from lipid profiles to establish an index for predicting the risk of having coronary event. The atherogenic index of plasma was strongly correlated with the Cystatin C, hence AIP can be used as better index for predicting the preclinical cardiovascular disease because of cost effectiveness in estimation of Cystatin C.

Atherogenic Index of Plasma (AIP) as a new marker of atherogenicity and directly related to the risk of atherosclerosis, is a simpleand inexpensive method to assess the severity of atherogenic dyslipidemia. 97% of adult patients with type 2 DM (T2DM) will havedyslipidemia including increased levels of TG, low HDL-C levels whereas LDL cholesterol levels had no effect. To determine the atherogenicindex of plasma in controlled and uncontrolled T2DM. A Cross-sectional study was conducted on 72 controlled T2DM samples and 112uncontrolled T2DM samples from Clinic of Endocrine and Methabolic dr Wahidin Sudirohusodo Hospital Makassar, starting from April-May 2013. Fasting glucose level, triglycerides, HDL-C and HbA1c determined using ABX Pentra 400 (colorimetric method). Data thenanalyzed with Mann Withney U test. Most of the samples are male, with the age range from 51-60 years old. Mean AIP is not so differentbetween the two groups (0.51±0.28 and 0.55±0.28 respectively). Fasting glucose level, triglycerides, HDL-C in T2DM uncontrolled werehigher than controlled. The atherogenic index of plasma of controlled T2DM group were 0.93 times lower than uncontrolled T2DM, MannWithney U test showed that there were no significant correlation between both of group (p>0.05). Atherogenic index of plasma cannotbe used to distinguish between controlled and uncontrolled T2DM.
