Study of Carotid Intima Media Thickness (CIMT) In Type 2 Diabetes Mellitus and Its Correlation with Glycaemic Control and Inflammatory Marker HsCRP

ABSTRACT

Background: Carotid Intima Media Thickness (CIMT) andCRP (C Reactive Protein) are have been used for measuringAtherosclerotic Risk in Diabetics. However there is paucity ofdata regarding their importance in Statin Naïve Diabetics.Aim: To study Correlation of CIMT with glycaemic control andhsCRP in Statin Naïve Diabetics.Materials and Methods: 80 Cases (Patient suffering from type2 Diabetes Mellitus) and 20 controls (non- diabetic healthpatients) presenting in outpatient department of a tertiaryHospital were included in this observational cross sectionalobservational study. Complete Blood Count, urine Routine andMicroscopy, urine for microalbuminuria, fasting plasma glucose(FPG), postprandial plasma glucose (PPPG), glycatedhaemoglobin (HbA1C), lipid profile, renal function test, hs-CRPand CIMT were evaluated in each individual. Independentsamples T-test was used to compare CIMT and hs-CRP bothcases and controls. Test of proportion and chi-square test wasused for association between categorical variables.Spearman’s method was used to assess correlation betweenhsCRP and CIMT.Results: 80 cases (Statin naïve and Non-smoker Diabeticpatients and 20 healthy controls were included in this study.Average CIMT in cases was significantly higher in Diabeticcases than Control (0.66 + 0.14 vs 0.56±0.05, difference= 0.10 mm, 95% C.I. (0.1 - 0.17), p < 0.0001). HsCRP wassignificantly correlated with average CIMT in Diabetic cases.(r=0.512, 95% C.I. 0.33-0.658, p<0.0001). Fasting Blood Sugarwas correlated with average CIMT in Diabetic cases. (r=0.234,95% C.I. 0.015-0.432, p=0.0366). Post Prandial Blood Sugarwas also correlated with average CIMT (r=0.300, 95% C.I.0.086-0.488, p=0.00677).Conclusion: Cardiovascular risk factors like glycaemic controland inflammatory markers like hsCRP are significantlyassociated with CIMT even in non-smoking and statin naïveDiabetics.
