Background: Carotid intima-media thickness (IMT) is a predictor of cerebral infarction. The incidence of cerebral infarction increases as atherosclerotic plaque size and external carotid artery stenosis progress.
Methods: Subjects were classified according to the degree of blood pressure control and carotid IMT was measured. The t-test and analysis of variance and Scheffe’s post-hoc test were used to determine differences in IMT according to the degree of blood pressure control. Crossover analysis with the chi-square test was used to evaluate differences in IMT and atherosclerotic plaque according to the degree of blood pressure control.
Results: There was no statistical association between the degree of blood pressure control and IMT, with a significance level of 0.290. There was no statistical association between the degree of blood pressure control and abnormal IMT, with a significance level of 0.224. There was no statistical association between the degree of blood pressure control and the presence of atherosclerotic plaque, with a significance level of 0.370.
Conclusion: The mean carotid IMT did not show a statistically significant difference, even when blood pressure was increased. The distribution of abnormal did not increase even if blood pressure control was improved. The presence of atherosclerotic plaque was not significantly associated with the degree of blood pressure control.
