Abstract:
Objectives To detect the carotid artery intima-media thickness (CIMT)with color Doppler ultrasound and to investigate the relationship between CIMT and new ischemic cerebrovascular disease. Methods From May 2012 to October 2013,the cluster random sampling method was used to consecutively enroll 4 412 60 -70 year old residences in Reqiu City for prospective study,including face to face health questionnaire survey,human body measurement,laboratory test,and neck vascular color Doppler ultrasonography. According to whether having new ischemic cerebrovascular disease,the patients who had ischemic cerebrovascular disease in 2013 were divided into either a case group (n = 251)or a control group (n =4 161). The single factor analysis,such as baseline data and CIMT levels in both groups were compared, and the related risk factors for ischemic cerebrovascular disease were analyzed. Results (1)The detection rates of hypertension,cerebrovascular disease,taking antiplatelet agents,carotid artery plaque of the case group were higher than those of the control group (62. 2% [n = 156]vs. 44. 2% [n = 1 838],45. 0%[n = 113]vs. 14. 9% [n = 622],55. 0% [n = 138]vs. 40. 0% [n = 1 663],and 65. 7% [n = 165]vs. 54. 5% [n = 2 266],all P < 0. 05). The systolic blood pressure,insulin,and CIMT levels were higher than those of the control group (158 [141,177]mmHg vs. 152 [137,169]mmHg,8. 07 [4. 77,12. 48]μU/ L vs. 6. 93 [4. 27,11. 60]μU/ L,0. 950 [0. 900,1. 000]mm vs. 0. 925 [0. 900,1. 000]mm,all P <0. 05). The cholesterol level was lower than that of the control group (4. 59 [4. 17,5. 26]mmol/ L vs. 4. 78 [4. 20,5. 36]mmol/ L,P < 0. 05). There were significant differences between the 2 groups. (2)Multivari-ate logistic regression analysis showed that histories of hypertension and cerebral vascular disease and CIMT thickening were the independent risk factors for new ischemic cerebrovascular disease (hypertension:OR, 1. 534,95% CI 1. 166 -2. 017,P = 0. 002;history of cerebral vascular disease:OR,3. 940,95% CI 2. 997 -5.180,P =0.000;and CIMT thickening:OR,12.122,95%CI 2. 327 -63. 163,P =0. 003). Conclusion CIMT, hypertension,and cerebrovascular disease are the independent risk factors for ischemic cerebrovascular disease in Renqiu City,and the monitoring of CIMT is very important.
