Methods:A total of 92 cases of patients with coronary heart disease with mild to moderate hypertension were selected as the object of observation, according to the random data table, they were divided into the control group (n=46) and observation group (n=46), and patients in the control group were treated with Nifedipine Controlled Release Table therapy, on this basis, the observation group patients were given telmisartan treatment, two groups were treated for 6 months. The levels of the blood pressure, inflammatory factors, vascular endothelial function and left ventricular function compared between the two groups before and after treatment. Results: There were no significant differences in the levels of SBP, DBP, hs-CRP, TNF-α, NO, ET-1, LVEF, LVEDD and LVESD in the two groups before treatment. After treatment, two groups of SBP, DBP, hs-CRP, TNF-α, ET-1, LVEDD and LVESD levels were significantly lower than those in the same group before treatment, and after treatment, the levels of SBP, DBP, hs-CRP, TNF-α, ET-1 and LVESD in the observation group were significantly lower than those in the control group, while there were no significant difference in the level of LVEDD between the two groups after treatment;Compared with level in the group before treatment, the levels of NO and LVEF in the two groups were significantly increased, and the observation group [(82.13±19.01) μmol/L, (52.83±7.45)%] was significantly higher than the control group ((67.37±13.08) μmol/L, (49.47±6.96)%)Conclusion: Telmisartan combined with Nifedipine Controlled Release Table in treating coronary heart disease with mild to moderate hypertension, can effectively control blood pressure, reduce the inflammatory stress, improve vascular endothelial function and left ventricular function of patients, has an important clinical value.展开更多

METHODS: A retrospective study was performed in 206 cases > or = 60 years old of EHT, CHD and NIDDM with LVH and 30 normal cases as control, out of 3195 consecutive autopsied cases from 1954 to 1996 in our hospital. Arterioles with diameters of 10 - 60 microm and capillaries in the muscular layer were shown by the methods of HE, Elastic fiber + VG staining and immunohistochemistry of CD31. Quantitative measurements on the arteriole density (AD), the ratio of arteriolar wall and cavity (RWC), capillary density (CD) and the area of endothelial cell (AEC) were performed with light microscope observation and image analysis by computer. According to the thickness of the left ventricle free wall, the severity of LVH was divided into four degrees from 0 to III. LVH of degree 0-III was observed in EHT group, while only LVH of degree I was found in CHD, EHT + CHD, and NIDDM groups. SAS system was used for statistical analysis. RESULTS: AD and RWC increased while CD and AEC decreased significantly with the progression of LVH in EHT groups (P展开更多
