【摘要】：目的探討二維斑點(diǎn)追蹤顯像技術(shù)評價(jià)2型糖尿病患者左心房功能的臨床應(yīng)用價(jià)值。方法對60例2型糖尿病患者分為左心室舒張功能正常組(A組,Ve/Va≥1)、左心室舒張功能減低組(B組,Ve/Va1)以及30例健康志愿者組(C組)。應(yīng)用二維斑點(diǎn)追蹤顯像技術(shù)測量各組左心房前壁、下壁、后壁、側(cè)壁、房間隔的應(yīng)變率(SR)。結(jié)果 A組與C組相比,A組SSR、ESR均減低(P0.05),ASR增加(P0.05);B組與C組相比,B組SSR減低(P0.05),ESR明顯減低(P0.01),左ASR增加(P0.05);A組與B組相比,B組SSR減低(P0.05),ESR減低(P0.05),ASR差異無統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論2型糖尿病患者左心室舒張功能正常時(shí)左心房功能已出現(xiàn)損害。2型糖尿病患者左心室舒張功能輕度減低時(shí),左心房助力泵功能增加,左心房儲存器功能和管道功能進(jìn)一步減低。
