彩色多普勒超声心动图对老年退行性心脏瓣膜病变的诊断价值探究

Diagnostic Value of Color Doppler Echocardiography in Elderly Patients with Degenerative Heart Valve Disease

目的研究老年退行性心脏瓣膜病变应用彩色多普勒超声心动图的诊断价值。方法方便选取2016年3月—2018年11月该院接诊的心内科老年病患100例为研究对象,将之按照年龄进行分组,当中,甲组40例的年龄在60~69岁之间,乙组35例的年龄在70~79岁之间,丙组25例的年龄在80~89岁之间。对3组都实行彩色多普勒超声心动图检查,了解其心脏病变的情况,并对各组的检测结果进行分析比较。结果100例病患中,明确诊断为老年退行性心脏瓣膜病变者有19例,占总比例的19.0%。甲组的阳性检出率为10.0%,乙组为20.0%,丙组为32.0%,组间比较差异有统计学意义(P<0.05)。19例阳性者中,主动脉瓣膜病变有12例(63.16%)。各组对诊断结果的满意度都比较高,甲、乙、丙3组的满意度依次是97.50%、97.14%、100.00%。结论于老年退行性心脏瓣膜病变中采用彩色多普勒超声心动图检查法,可清楚地显示出患者瓣膜的厚度、活动度以及回声强弱等,并有助于临床医师了解患者瓣环的钙化以及反流情况,能够为患者病情的诊断提供重要指导,建议采纳。

Objective To study the diagnostic value of color Doppler echocardiography in elderly patients with degenerative heart valve disease. Methods A total of 100 elderly patients with cardiology admitted to our hospital from March 2016 to November 2018 were convenient selected and enrolled in the study. The age group was divided into 60-69 years old. 35 patients in group B were between 70-79 years old, and 25 patients in group C were between 80-89 years old. Color Doppler echocardiography was performed on all three groups to understand the changes of heart disease, and the results of each group were analyzed and compared. Results Of the 100 patients, 19 were diagnosed as degenerative heart valve disease in the elderly, accounting for 19.0% of the total. The positive detection rate of group A was 10.0%, that of group B was 20.0%, and that of group C was 32.0%. The difference between groups was statistically significant (P<0.05). Among the 19 positive cases, there were 12 cases (63.16%) of aortic valve disease. The satisfaction of the diagnosis results was higher in each group. The satisfaction rates of group A, B and C were 97.50%, 97.14% and 100.00%, respectively. Conclusion Color Doppler echocardiography in elderly degenerative heart valve disease can clearly show the thickness, activity and echo intensity of the patient's valve, and help clinicians understand the patient's annulus. Calcification and reflux can provide important guidance for the diagnosis of patients' condition and recommend adoption.
