摘　　要：目的 探究超声心动图对肺动脉高压患者右心功能的评估价值,并分析其参数与纽约心脏病学会(NYHA)心功能分级的相关性。方法 选取我院2021年2月至2022年2月120例肺动脉高压患者为对象,实施超声心动图诊断,以肺动脉收缩压(PASP)为依据进行分组,包括轻度(A组)、中度(B组)与重度(C组),对比不同患者的超声心动图参数,分析各参数与NYHA心功能等级相关性。结果 3组患者三尖瓣环收缩期峰值速度(S′)、三尖瓣环收缩期位移(TAPSE)、右室面积变化分数(RVFAC)、右室射血分数(RVEF)、每博输出量(SV)、收缩末容积(RVESV)、右心室舒张末容积(RVEDV)比较,各组间差异有统计学意义(P<0.05)。B组患者Ⅲ级、Ⅳ级发生率高于A组;B组,A组患者Ⅰ级发生率、Ⅱ级发生率高于C组,B组Ⅱ级发生率高于C组,差异均有统计学意义(P<0.05)。Spearman相关性分析示,NYHY分级与S′(P=0.018)、TAPSE (P=0.019)、RVFAC (P=0.019)、RVEF(P=0.028)呈负相关,与RVEDV(P=0.020)、RVESV(P=0.019)、RVSV(P=0.018)呈正相关。结论 采用超声心动图诊断肺动脉高压患者,可评估右心功能,指导患者用药,具有显著应用价值。Objective Explore the value of echocardiography on right heart function in patients with pulmonary arterial hypertension and analyze its parameters with the New York Heart Association(NYHA)cardiac function grade.Methods A total of 120 patients with pulmonary hypertension from February 2021 to February 2022 in our hospital were selected for echocardiography diagnosis.The patients were divided into a mild group(Group A),moderate group(Group B),and Severe Group(Group C)according to pulmonary artery systolic pressure(PASP),the echocardiography parameters of dfferent patients were compared and the correlation between Nyha Cardiac function class and the pa-rameters was analyzed.Results Peak systolic velocity(S'),tricuspid annulus systolic displacement(TAPSE),right ventricular area change fraction(RVFAC),right ventricular ejection fraction(RVEF),stroke volume(SV),endsystolic volume(RVESV),and end-diastolic volume(RVEDV)of right ventricle were compared among the three groups,there were significant differences among the groups(P<0.05).The rate of Grade II and Grade IV in Group B was higher than that in Group A,the rate of Grade I and Grade I in Group A was higher than that in Group C,and the rate of Grade II in Group B was higher than that in Group C,the difference was statistically significant(P<0.05).Spearman correlation analysis showed that NYHY classification was negatively correlated with S'(P=0.018),TAPSE(P=0.019),RVFAC(P=0.019),RVEF(P-0.028),and positively correlated with RVEDV(P=0.020),RVESV(P=0.019),RVSV(P=0.018).Conclusion The use of echocardiography in the diagnosis of pulmonary hypertension can be used to assess right ventricular function and to guide the use of drugs in patients with pulmonary hypertension.
