【摘要】 目的探讨心脏彩色多普勒超声诊断高血压左室肥厚伴心力衰竭的临床价值。方法选取2016年3月至2018年3月在鹰潭市人民医院进行治疗的高血压左室肥厚伴心力衰竭患者45例作为观察组,同期40例健康体检者作为对照组,应用心脏彩色多普勒超声检查所有受检者的左室舒张末期内径(LVEDd)、左室收缩末期内径(LVESd)、左房内径(LAD)、二尖瓣口舒张早期最大血流速度(E峰)/二尖瓣环舒张早期最大运动速度(Ea峰)、左室短轴缩短分数(LVFS)和左心射血分数(LVEF)。结果观察组患者的LVESd、LVEDd、LVFS分别为(30.48±0.86) mm、(53.48±2.84) mm、(33.94±1.92)%,均明显高于对照组的(28.92±0.92) mm、(48.46±2.61) mm、(31.08±2.15)%,差异均有统计学意义(P<0.05);观察组患者的LVEF、E/Ea分别为(56.42±5.59)%、(6.51±1.27),均明显低于对照组的(66.28±5.31)%、(12.26±2.84),差异均有统计学意义(P<0.05);观察组中心功能Ⅰ级、Ⅱ级和Ⅲ级患者的LVEDd分别为(49.22±8.95) mm、(52.06±8.87) mm、(60.41±9.25) mm,LAD分别为(43.69±5.15) mm、(50.82±8.86) mm、(60.35±6.78) mm,呈明显增高趋势,心功能Ⅰ级、Ⅱ级和Ⅲ级患者LVEF分别为(59.17±6.62)%、(53.67±7.28)%、(49.42±4.46)%,呈明显降低趋势,各指标间比较差异均有统计学意义(P<0.05)。结论心脏彩色多普勒超声对高血压左室肥厚伴心力衰竭诊断价值较高,其不仅能够准确的对该疾病进行鉴定,并且还可以对心力衰竭严重程度做出评估。更多还原

【Abstract】 Objective To investigate the value of color Doppler echocardiography in the diagnosis of left ventricular hypertrophy with heart failure in patients with hypertension. Methods From March 2016 to March 2018, 45 hypertensive patients with left ventricular hypertrophy and heart failure in Yingtan People’s Hospital were selected as the observation group and 40 healthy people as the control group. The left ventricular end-diastolic diameter(LVEDd), left ventricular end-systolic diameter(LVESd) and left atrial diameter(LAD) were examined by color Doppler echocardiography, as well as maximum early diastolic velocity of mitral orifice(peak E)/peak early diastolic velocity of mitral annulus(peak Ea), left ventricular short axis shortening(LVFS), and left ventricular ejection fraction(LVEF). Results The LVESd, LVEDd and LVFS of the observation group were(30.48±0.86) mm,(53.48±2.84) mm,(33.94±1.92)%, respectively, which were significantly higher than(28.92±0.92) mm,(48.46±2.61) mm,(31.08±2.15)% of the control group(P<0.05), and the LVEF and E/Ea of the observation group were(56.42 ± 5.59)%,(6.51 ± 1.27), significantly lower than(66.28±5.31)%,(12.26±2.84) in the control group(P<0.05). LVEDd in patients with cardiac function grade Ⅰ, Ⅱ and Ⅲwere(49.22±8.95) mm,(52.06±8.87) mm,(60.41±9.25) mm, respectively, and the LAD values were(43.69±5.15) mm,(50.82±8.86) mm and(60.35±6.78) mm, respectively, showing a significant increasing trend. LVEF in patients with cardiac function grade Ⅰ, Ⅱ and Ⅲ were(59.17±6.62)%,(53.67±7.28)%,(49.42±4.46)%, and the difference was statistically significant(P<0.05). Conclusion Color Doppler echocardiography has a high diagnostic value in hypertensive left ventricular hypertrophy with heart failure. It can not only accurately identify the disease, but also evaluate the severity of heart failure.更多还原
