随着我国老龄化的进一步扩大,主A瓣的退行性病变日渐增多,应用二维彩色多普勒诊断技术对198例患者进行定性定量分析并测定其心功能,与对照组相比差异显著(P<0.01),对疾病的早期诊断及治疗有一定的价值.
With the further expansion of the aging of our country, the degenerative changes of the main A-flap were increasing. Two-dimensional color Doppler diagnostic technique was used to qualitatively and quantitatively analyze 198 patients and determine their cardiac function, which was significantly different from the control group P <0.01), the early diagnosis and treatment of diseases have a certain value.
