Fig 2.
The relation between cIMT and CVRFs.
A shows the cIMT by the age. Box 1: age 40–50 years; Box 2: age 50–60 years; Box 3: age 60–70 years; Box 4: >70 years. B demonstrates the cIMT by the types of chronic disease. Box 1:hypertension; Box 2: dyslipidemia; Box 3: diabetes. C shows the cIMT by the number of chronic cardiovascular diseases. Box 0:without chronic cardiovascular disease; Box 1:1 type of chroinc cardiovascular disease; Box 2: 2 types of chronic cardiovascular diseases; Box 3:3 types of chronic cardiovascular diseases. D shows the cIMT by two different chronic cardiovascular diseases. Box 1: Combination of hypertension with diabetes; Box 2: combination of dyslipidemia with diabetes; Box 3: combination of hypertension with dyslipidemia.
Table 3.
The relationship between different chronic cardiovascular diseases and degrees of severity.
Note: * Due to the presence of the desired frequency <5, the use of Fisher's exact test.Table 4 shows the relationship between number of chronic cardiovascular diseases and degree of severity. In the group with no chronic disease, cIMT was normal in more than half of the subjects. With the increasing number of chronic cardiovascular disease, the exposure rate of subject’s intimal thickening, plaque formation and moderate carotid stenosis increased. Fig 2C shows the cIMT in subjects with different numbers of chronic cardiovascular diseases with significant difference noticed between groups (p<0.05).
