Characteristics Of Intracranial And Extracranial Arteries In Hypertensive And Non-hypertensive Patients With Cerebral Infarction

Objective: Study the vascular characteristics of head and neck among cerebralinfarction patients with hypertension or non-hypertension.Methods: We collected166cerebral infarction patients checked by computedtomography angiography(CTA) of head and neck. Patients were divided intohypertension group, control group, hypertension with diabetes group, hypertensionwith dyslipidemia group, hypertension with diabetes and dyslipidemia group, diabetesgroup, dyslipidemia group, diabetes with dyslipidemia group by factorial designscheme. The CTA results of head and neck were rated. The plaque score, extracranialvessel stenosis degree score of head and neck and intracranial artery stenosis score ofhypertensive patients were compared with that of non-hypertensive patients. And allscores were compared between each group.Results: There are statistical significances about the plaque score、extracranial vesselstenosis degree score of head and neck and intracranial artery stenosis score betweenhypertensive patients and non-hypertensive patients (all P<0.05). The three kinds ofscore in hypertension patients are much higher than non-hypertension patients.Comparison of all groups score: The three kinds of score in hypertension withdiabetes and dyslipidemia group are respectively much higher than other groups (allP<0.05). Plaque score in hypertension with dyslipidemia group is much higher thanthe dyslipidemia group(P <0.05). Extracranial vessel stenosis degree score of headand neck in hypertension with diabetes group is respectively higher than controlgroup, hypertension group and dyslipidemia group.There are significant differences(all P <0.05). Extracranial vessel stenosis degree score of head and neck inhypertension with dyslipidemia group is higher than control group, hypertensiongroup and dyslipidemia group respectively (all P <0.05). Intracranial artery stenosis score in hypertension with dyslipidemia group is respectively obviously higher thancontrol group, diabetes group and dyslipidemia group (all P <0.05).Conclusion:1Hypertension may be closely associated with intracranial artery stenosis.Hypertension is a significant risk factor for multiple stenosis and single stenosisof intracranial artery.2Compared with the patients without hypertension, cerebral infarction patientswith hypertension may show stenosis of more arteries and more diffuse plaquesof arteries in extracranial vascular of head and neck.3Compared with cerebral infarction patients who have hypertension or metabolicsyndrome, cerebral infarction patients who are in hypertension with diabetes anddyslipidemia group may show more serious atherosclerosis and vascular stenosisdegree in intracranial and extracranial arteries.
