摘要
目的观察超声心动图在老年心肌梗死后心力衰竭患者右心功能评估中的应用价值。方法70例老年心肌梗死后心力衰竭患者,根据患者心功能分级不同分为Ⅰ级组(37例)、Ⅱ级组(22例)和Ⅲ级组(11例)。三组患者均给予超声心动图检查。比较三组患者左室射血分数(LVEF)、右室射血分数(RVEF)、右心室舒张末期容积(RVEDV)、右心室收缩末期容积(RVESV)、右心室每搏输出量(RVSV)。结果三组患者LVEF、RVEF、RVEDV、RVESV、RVSV比较差异具有统计学意义(P<0.05)。其中,Ⅲ级组患者LVEF、RVEF、RVSV低于Ⅰ级组及Ⅱ级组,RVEDV、RVESV水平高于Ⅰ级组及Ⅱ级组,差异具有统计学意义(P<0.05);Ⅱ级组患者LVEF(36.21±3.37)%、RVEF(42.55±6.13)%、RVSV(53.26±3.17)ml低于Ⅰ级组的(43.16±3.55)%、(48.29±6.44)%、(57.29±6.03)ml,RVEDV(131.47±5.29)ml、RVESV(67.19±5.13)ml高于Ⅰ级组的(118.49±7.55)、(58.64±5.03)ml,差异具有统计学意义(P<0.05)。结论超声心动图能够对老年心肌梗死后心力衰竭患者的右心功能进行有效评估。
Objective To observe the echocardiographic evaluation of right ventricular function in elderly patients with heart failure after myocardial infarction.Methods A total of 70 elderly patients with heart failure after myocardial infarction were divided into gradeⅠgroup(37 cases),gradeⅡ(22 cases)and gradeⅢgroup(11 cases)by different grades of cardiac function.Echocardiography was performed in all three groups.Comparison was made on left ventricular ejection fraction(LVEF),right ventricular ejection fraction(RVEF),right ventricular end diastolic volume(RVEDV),right ventricular end systolic volume(RVESV)and right ventricular stroke volume(rVSV)in three groups.Results There was no statistically significant difference in levels of LVEF,RVEF,RVEDV,RVESV and RVSV in three groups(P<0.05).The levels of LVEF,RVEF and RVSV in gradeⅢgroup was lower than those in gradeⅠgroup and gradeⅡgroup,and levels of RVEDV and RVESV was higher than those in gradeⅠgroup and gradeⅡgroup.Their difference was statistically significant(P<0.05).The levels of LVEF(36.21±3.37)%,RVEF(42.55±6.13)%and RVSV(53.26±3.17)ml in gradeⅡgroup was lower than(43.16±3.55)%,(48.29±6.44)%and(57.29±6.03)ml in gradeⅠgroup,and levels of RVEDV(131.47±5.29)ml and RVESV(67.19±5.13)ml was higher than(118.49±7.55)and(58.64±5.03)ml in gradeⅠgroup.Their difference was statistically significant(P<0.05).Conclusion Echocardiography can effectively evaluate the right ventricular function in elderly patients with heart failure after myocardial infarction.
