心血管疾病患者颈动脉彩超表现与血脂和血糖的对照研究

目的　通过对心血管病的患者颈动脉彩超表现与血脂和血糖的对照研究 ,了解颈动脉粥样硬化的发生机制及其的早期症状。方法　对 15 4例心内科住院患者做颈动脉超声检查及血脂和血糖检查 ,并对结果进行统计分析。结果　颈总动脉前后径 (9.10± 0 .94 )mm ,横径(9.0 2± 1.0 3)mm ;管径大于 10mm分别有 18例和 19例。扭曲有 2 5例 ,大多数为单个扭曲 ,角度为 14 0～ 16 0°。内中膜增厚最明显者为 4 .9mm ;有斑块 6 4例 ,较大个长 8.7mm ,宽 5 .6mm ,厚 4 .3mm。对颈动脉有斑块或无与验血指标在正常值内或超过正常值进行卡方检验 ,总胆固醇和三酰甘油指标有显著性差异 (P <0 .0 5 )。结论　彩超能动态地观察、评价动脉粥样斑块的进程 ,正逐渐成为评价颈动脉疾病的首选方法。笔者认为胆固醇和三酰甘油是可以引起颈动脉粥样硬化的次要因素 ,主要因素还是取决于血管内膜功能。

Control study of color Doppler flow imaging of carotid artery with blood-sugar and blood-lipid in angiocardiopathy

Objective It is to comprehend the mechanism of atherosclerosis of carotid artery and its early symptom through control study of color Doppler flow imaging of carotid artery with blood-sugar and blood-lipid in angiocardiopathy. Methods 154 inpatients in the heart department were detected the carotid artery with color Doppler flow imaging and blood-sugar and blood-lipid, and the statistical treatment of result was done. Results Vertical diameter of carotid artery was (9.10±0.94) mm, and transverse diameter was (9.02±1.03) mm. The cases that the vertical diameter and transverse diameter of carotid artery was larger than 10 mm were respectively 18 cases and 19 cases. The distortion of blood vessel was 25 cases, a lot of them were single cases, the angles were 140～160°. Intima-media of carotid artery was evidently thickened for 4.9 mm. The patients with plaque were 64 cases. The larger plaque was length for 8.7 mm, wide for 5.6 mm, thick for 4.3 mm. The chi-square was made between carotid artery with plaque or not and blood test was the normal or superior to normal. The index of cholesterol and triglyceride had significant difference (P<0.05). Conclusion Color Doppler flow imaging can dynamically observe and evaluate the process of atherosclerosis plaques. And it is the first method to evaluate disease of carotid artery. Authors consider that cholesterol and triglyceride are the second factor which could cause carotid artery atherosclerosis, and the main factor is tunica intima function of blood vessel.
