超声心动图诊断老年冠心病患者肺动脉高压的临床价值分析

目的 分析在老年冠心病患者群体中应用超声心动图检测肺动脉高压的临床应用价值。方法 选取我院2015年1月~2016年3月收治的老年冠心病患者84例，按照肺动脉收缩压水平随机将其分为A、B、C、D四组，每组21例。运用超声心动图针对四组患者展开检查诊断，观察比较四组患者的RVAW和LVPW。结果 B组、C组和D组的RVAW分别为（4.26±0.92）mm、（7.98±1.14）mm和（7.52±4.07）mm，均大于A组的（3.44±0.87）mm，差异具有统计学意义（P＜0.05）。B组的LVPW大于A组，C组的LVPW小于A组，但差异无统计学意义（P＞0.05）；D组的LVPW为（56.51±2.47）mm，小于A组的（64.47±3.95）mm，差异具有统计学意义（P＜0.05）。结论 运用超声心动图检查技术测定老年冠心病患者的RVAW和LVPW，对于检测诊断肺动脉高压症状具备一定的临床应用价值，结合其他临床诊断标准，能够提高老年冠心病患者群体的肺动脉高压诊断准确率，改善患者的整体生存质量。

Clinical Value of Echocardiography in Diagnosis of Pulmonary Hypertension in Elderly Patients with Coronary Heart Disease

Objective To analyze the clinical value of echocardiography in the detection of pulmonary hypertension in elderly patients with coronary heart disease. Methods 84 elderly patients with coronary heart disease admitted to our hospital from January 2015 to March 2016 were randomly divided into four groups: A, B, C, and D according to the level of pulmonary systolic blood pressure, 21 cases in each group. Echocardiography was used to diagnose the four groups of patients, and the RVAW and LVPW of the four groups were compared.Results The RVAW of group B, group C and group D were (4.26±0.92) mm, (7.98±1.14) mm and (7.52±4.07) mm, respectively, which were greater than those of group A(3.44±0.87) mm. The difference was statistically significant(P<0.05). The LVPW of group B was greater than that of group A. The LVPW of group C was smaller than that of group A, but the difference was not statistically significant(P>0.05); the LVPW of group D was (56.51±2.47) mm, which was smaller than that of group A(64.47±3.95) mm，the difference was statistically significant(P<0.05). Conclusion The use of echocardiography to measure RVAW and LVPW in elderly patients with coronary heart disease has certain clinical value for the detection of pulmonary hypertension symptoms. Combined with other clinical diagnostic criteria, it can improve the diagnostic accuracy of pulmonary hypertension in elderly patients with coronary heart disease. Improve the overall quality of life of patients.
