【摘要】：目的:應(yīng)用速度向量成像技術(shù)觀察慢性心力衰竭(CHF)患者左心室短軸徑向各節(jié)段心肌應(yīng)變和應(yīng)變率變化,評(píng)價(jià)左室收縮功能及心功能。方法:選取寧夏醫(yī)科大學(xué)總院心腦血管病醫(yī)院心血管內(nèi)科2014-10-2015-05收治的CHF患者100例(心衰組),根據(jù)NYHA心臟功能分級(jí)分組:NYHAⅡ級(jí)組35例、Ⅲ級(jí)組32例、Ⅳ級(jí)組33例。選擇同期30例體檢健康者為正常對(duì)照。ELISA法測(cè)得血清BNP水平,采用超聲心動(dòng)圖常規(guī)測(cè)量左室射血分?jǐn)?shù)(LVEF)、左室收縮末期內(nèi)徑(LVDS)、左室舒張末期內(nèi)徑(LVDD)及左室短軸縮短率(LVFS),選擇VVI模式,測(cè)量左室胸骨旁短軸切面前壁、側(cè)壁、后壁、下壁、后間隔及前間隔的應(yīng)變和應(yīng)變率。結(jié)果:心衰組各節(jié)段ε、SRs顯著低于對(duì)照組,除二尖瓣水平前間隔ε、乳頭肌水平側(cè)壁、后壁SRs外,差異均有統(tǒng)計(jì)學(xué)意義(均P0.05)。NYHAⅡ~Ⅳ級(jí)組各節(jié)段ε、SRs基本呈下降趨勢(shì),與正常對(duì)照組相比差異有統(tǒng)計(jì)學(xué)意義(P0.05)。NYHA分級(jí)Ⅱ級(jí)與Ⅲ級(jí)、Ⅲ級(jí)與Ⅳ級(jí)比較差異無統(tǒng)計(jì)學(xué)意義。整體平均ε、SRs與LVEF、LVFS呈負(fù)相關(guān),與LVDd、LVDs、BNP呈正相關(guān)。結(jié)論:VVI可用于定量檢測(cè)左心室局部和整體的應(yīng)變和應(yīng)變率,為評(píng)價(jià)心功能和診斷CHF提供新的方法。
[Abstract]:Objective: to evaluate the left ventricular systolic function and cardiac function in patients with chronic heart failure (CHF) by using velocity vector imaging to observe the changes of myocardial strain and strain rate at different radial segments of the left ventricular short axis. Methods: 100 CHF patients were selected from the Department of Cardiovascular and Cerebrovascular Disease, Department of Cardiovascular and Cerebrovascular Diseases, General Hospital of Ningxia Medical University, 2014-10-2015-05. According to NYHA cardiac function classification, 35 cases were divided into two groups: group 鈪，
