Methods: the study was conducted from June 2020 to March 2021. The patients were mainly elderly patients with severe heart failure. A total of 86 patients were divided into the control group and the study group, respectively. The former received routine treatment, while the latter received metoprolol and irbesartan and hydrochlorothiazide simultaneously. After treatment, the effects of the two models were compared and evaluated from the aspects of cardiac function index, quality of life and treatment efficiency. Results: before treatment, the cardiac function and quality of life of the patients were evaluated. The difference between the average values of the patients in each group was small (P > 0.05). The difference in data was not statistically significant. After treatment, the relevant indexes were evaluated again. The effective rate of the control group was 83.72%, LIHFe score was (26.31±3.84), BNP was (900.57±36.92)ng/ml, LVEF was (38.72±3.73)%, LVEDD was (51.35±4.74)mm and LVESD was (42.49±3.57) mm. However, the above indexes of the research group, they were95.35%、(21.39±3.06)、(259.67±23.73)ng/mL, (44.47±3.29)%, (51.35±4.74)mm、(42.49±3.57)mm respectively. All the indexes in the latter group had advantages, P < 0.05. Conclusion: the combination of metoprolol and irbesartan and hydrochlorothiazide has excellent applicability. It can better help the emergency internal medicine department to complete the treatment of elderly patients with severe heart failure, improve the quality of life, optimize the cardiac function, and has extremely strong promotion and application value.展开更多

For x-ray differential phase contrast imaging, a strong attenuation signal acts as an overwhelming background intensity that obscures the weak phase signal so that no obvious phase-gradient information is detectable in the raw image. By subtracting one interferogram from another, chosen at particular intervals,the phase signal can be isolated and magnified.展开更多
