    【摘要】?目的?探讨二维斑点追踪成像技术(2D-STE)聯合血清脑钠肽(BNP)对冠心病右心室功能的评价作用。方法?选择2018年1月至2019年6月在右江民族医学院附属医院心血管内科住院经冠脉造影确诊为冠心病的患者。根据冠脉造影的结果，按照Gensini积分评分的标准，将冠心病患者分为：冠心病轻度组(Gensini积分≤50分)23例，冠心病重度组(Gensini积分>50分)19例。另选取门诊健康体检者25人作为对照组。检测并比较各组受检者的左室射血分数(LVEF)、BNP、右室游离壁各节段纵向收缩期应变(LS)、应变率(LSRs)及右室整体应变(GLS)，分析GLS、LVEF、BNP三者的相关性。结果?冠心病轻度组、重度组与对照组三组间LVEF、BNP测值比较差异有统计学意义(P0.05)。冠心病轻度组右室游离壁各节段应变率(LSRs)与对照组比较差异有统计学意义(P 50). In addition， 25 healthy outpatients were selected as control group. And then， left ventricular ejection fraction (LVEF)， serum BNP， longitudinal systolic strain (LS) of all segments of right ventricular free wall， strain rate (LSRs) and right ventricular global strain (GLS) were measured and compared， and the correlation of GLS， LVEF and BNP was analyzed. Results?There were statistically significant differences in LVEF and BNP values between the mild coronary heart disease group ......
