With the development of social science and technology and people’s demand for exploring the micro world, digital microscope technology came into being. Microscope image processing technology has been widely used in industrial micromanipulation, biomedicine, and cultural relic identification and preservation. In order to in-depth study the use of microscope image technology to observe the thickness of the carotid artery intima-media in hypertensive patients to find out whether it is feasible to explore many risk factors for cardiovascular development, this article uses data analysis, concept analysis, and graphic construction methods to collect samples, analyzed the image, streamlined the algorithm, and created a microscope image that can study its risk factors. The severity of hypertension, diabetes, and other factors affects the thickness of carotid arteries and cardiovascular diseases. The results show that the longer the duration of hypertension, the higher the central and peripheral blood pressure, the higher the height, and the higher the central blood pressure, which is relatively low. The detection rate of elevated central blood pressure is higher (76.8%). The second group (53.6%) and the third group (49.2%) ( P < 0.008 ); older age, the central blood pressure is relatively high, and the detection rate of central blood pressure increases (75.5%). It is higher than normal blood pressure (24.5%), so it can be concluded that hypertension not only affects central blood pressure but also peripheral blood; height and age are independent factors that affect central blood pressure. It is basically realized that starting from the microscope image, many risk factors of cardiovascular disease have been successfully analyzed.

Object The purpose of this study was to evaluate and compare the long-term effects of carotid endarterectomy (CEA) and carotid artery stenting (CAS) on blood pressure (BP). Methods Between January 2003 and December 2009, 134 patients underwent 145 procedures for treatment of carotid artery stenosis. Patients with at least 1 year of clinical and radiographic follow-up after treatment were included in this study. A total of 102 patients met this criterion and were placed in the CEA group (n = 59) or the CAS group (n = 43) according to their treatment. The percentage change in BP decrement and the number of patients with a normotensive BP were evaluated and compared between the groups. Results There were no significant differences between the groups with regard to baseline characteristics. Compared with the pretreatment BP, the follow-up BPs were significantly decreased in both groups. At the 1-year followup, the percentage change in the BP decrement was greater in the CAS group (percentage change: systolic BP 9.6% and diastolic BP 12.8%) than in the CEA group (percentage change: systolic BP 5.9% [p = 0.035] and diastolic BP = 8.1% [p = 0.049]), and there were more patients with a normotensive BP in the CAS group (46.5%) than in the CEA group (22.0%, p = 0.012). Conclusions Both CEA and CAS have BP-lowering effects. Carotid artery stenting seems to have a better effect than CEA on BP at the 1-year follow-up.
