ABSTRACT
Background: Most of the studies on cardiovascular risk factors are concentrated on adults. But atherosclerotic process begins in childhood and is influenced by genetics, diet and life style. Hence, present study was undertaken. The objectives of the study were to study lipid profile and other cardiovascular risk factors like hypertensive status, BMI(Body mass index) in children aged between 5years and 18 years born to parents having premature IHD(Ischemic heart disease), to study diet and life style factors in study group having family history of IHD, to study the sociodemographic profile of dyslipidemia.Methods: A 200 Cases of premature IHD were selected. Their children(n=200) in the age group of 5 to 18 years were selected and analysed for cardiovascular risk factors. They were compared with 200 normal children without any family history of IHD.Results: On comparison of mean lipid profile between cases and controls HDL cholesterol was very low amongst cases (p=0.001). The mean values of triglycerides and VLDL were very high amongst cases (p=0.001). The mean atherogenic index (AI) was high amongst cases (p=0.001). Prehypertension or hypertension was seen amongst 8.5% cases (p=0.004). Amongst the cases 19.5% had excess junk food intake (p=0.001). 51.5% of cases had sedentary life style (p=0.001).Conclusions: Children in our area born to parents with premature IHD have significant incidence of dyslipidaemia. There is an increased incidence of other cardiovascular risk factors like hypertension, excess junk food intake, sedentary life style in these children.
ABSTRACT
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 & 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<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
