Abstract

To measure and calculate the carotid arterial stiffness index(SI) in different degree of at-risk cerebral infarction by ultrasonograph. According to the relationship between carotid artery stiffness and carotid atherosclerosis, it ispossible to provide an early prevention for cerebral infarction. Methods:　The carotid artery of 40 high-risk cases and the 40 mild dangerous cases with hypertension were assessed by M type ultrasonic of color Doppler ultrasonography, calculation of SI by means of the diameter of common carotid artery wall in the systolic and diastolic cardiac cycle were performed. Changing of serum high sensitive C-reactive protein(hs-CRP) to assess the relationship between atherosclerosis and arterial stiffness. Results: ①The SI and hs-CPR of hypertension on the high-risk group were higher than the mild dangerous group obviously, and had positively correlation. ②After the age, sex, smoking and family history were adjusted, the blood pressure, blood glucose and blood fat are still playing an extremely positive role on arterial stiffness increasing. Conclusion: Carotid arterial stiffness reflects the characteristic of the functional change of carotid artery in preclinical, and provides an earlier warning for those who tend to suffer cerebral infarction.
