This paper was aimed to explore the application of the block matching pyramid (BMP) algorithm in echocardiographic spot tracking in patients with coronary heart disease (CHD) and angina pectoris, as well as the effect of Shexiang Baoxin pills (a kind of drug containing musk, which is good for cardiac diseases) on blood lipids, cardiac function, and curative effect. 206 patients with CHD angina pectoris in the hospital from July 2018 to May 2020 were selected as the research subjects and were enrolled into the control (Ctrl) group (conventional treatment, = 103) and the observation group (the Shexiang Baoxin pill was given on the basis of conventional treatment, = 103) in random. Then, the patients' echocardiograms were obtained, and the BMP algorithm was used to track the echocardiograms. At 12 months after treatment, the total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were compared. Besides, the differences between left ventricular end-systolic volume (LVESV), left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic volume (LVEDV), left ventricular end-diastolic dimension (LVEDD), cardiac index (CI), cardiac output (CO), and LVEF were observed. Finally, the efficacy of angina pectoris and electrocardiogram was calculated. It was found that the BMP algorithm can track the echocardiograms and display the movement and displacement of the patients' left ventricle. After treatment, in contrast with the Ctrl, the levels of TC, TG, and LDL-C in the observation group were obviously lower ( < 0.05); the LVESV, LVEDV, and LVEF were obviously lower ( < 0.05), the LVESD, LVEDD, CO, and CI were obviously higher ( < 0.05), the total score of angina after treatment was obviously lower ( < 0.05), and the total effective rates of angina pectoris and echocardiogram were obviously higher ( < 0.05). In conclusion, echocardiographic spot tracking can realize the diagnosis of patients with CHD angina pectoris, and Shexiang Baoxin pill can regulate the blood lipid level and improve the echocardiographic indicators and the clinical efficacy is obvious.
本文旨在探讨块匹配金字塔（BMP）算法在冠心病（CHD）和心绞痛患者超声心动图斑点跟踪中的应用，以及麝香保心丸（一种含有麝香的药物，对心脏疾病有好处）对血脂、心功能和疗效的影响。选取 2018 年 7 月至 2020 年 5 月我院收治的 206 例 CHD 心绞痛患者为研究对象，随机分为对照组（常规治疗，n=103）和观察组（在常规治疗基础上加用麝香保心丸，n=103）。然后，对患者进行超声心动图检查，并应用 BMP 算法对超声心动图进行跟踪。治疗 12 个月后，比较总胆固醇（TC）、三酰甘油（TG）、低密度脂蛋白胆固醇（LDL-C）和高密度脂蛋白胆固醇（HDL-C）。此外，观察左心室收缩末期容积（LVESV）、左心室收缩末期直径（LVESD）、左心室舒张末期容积（LVEDV）、左心室舒张末期内径（LVEDD）、心指数（CI）、心输出量（CO）和左心室射血分数（LVEF）的差异。最后，计算心绞痛和心电图的疗效。结果发现，BMP 算法可以对超声心动图进行跟踪，并显示患者左心室的运动和位移。治疗后，与对照组相比，观察组 TC、TG 和 LDL-C 水平明显降低（<0.05）；LVESV、LVEDV 和 LVEF 明显降低（<0.05），LVESD、LVEDD、CO 和 CI 明显升高（<0.05），治疗后心绞痛总评分明显降低（<0.05），心绞痛和心电图总有效率明显升高（<0.05）。综上所述，超声心动图斑点跟踪可实现 CHD 心绞痛患者的诊断，麝香保心丸可调节血脂水平，改善超声心动图指标，临床疗效显著。
