Abstract

CONTEXT: Carotid intima-media thickness (CIMT) and apolipoproteins have been found as a risk factor for ischemic stroke OBJECTIVE: The objective was to study the carotid intima-media thickness, apolipoproteins, and their relation in patients of ischemic stroke in central rural India. SETTINGS AND DESIGN: A cross-sectional study was performed in a rural hospital in central India. MATERIALS AND METHODS: In all patients of ischemic stroke proven by computerized tomography (CT), CIMT, apolipoprotein A-I (ApoA-I), and apolipoprotein B(ApoB) were measured. STATISTICAL ANALYSIS USED: We used Student's t-test to compare means, a chi-square test to compare proportions, and a Mann-Whitney test to compare medians. A P value <0.05 was considered significant. RESULTS: The mean age of our study population (N=106) was 61 years. The mean CIMT was 0.83 mm ranging from a minimum of 0.45 mm to a maximum of 1.096 mm. Mean CIMT was significantly higher than expected 0.67 values, which was calculated according to the age of the study population. The association of decreased ApoA-I < 100 mg/dl and increased ApoB > 90 mg/dl with CIMT > 0.7 mm was statistically significant with P<0.001. CONCLUSIONS: The CIMT in computerized tomography-proven ischemic stroke was significantly higher than expected for the age of the study population. The relation of decreased ApoA-I and increased ApoB with CIMT > 0.7 mm was also statistically significant.
