【摘要】：目的:應(yīng)用二維斑點(diǎn)追蹤成像技術(shù)評(píng)估不同年齡的健康孕婦在妊娠期間左室心肌整體長(zhǎng)軸應(yīng)變的變化規(guī)律。方法:按不同年齡對(duì)健康孕婦和未孕女性分組,35歲分為A組(年輕組),≥35歲分為B組(高齡組)。對(duì)未孕女性進(jìn)行超聲心動(dòng)圖檢查,對(duì)孕婦在妊娠8周、12周、16周、20周、24周、28周、32周、36周時(shí)進(jìn)行超聲心動(dòng)圖檢查,分析左室整體心肌長(zhǎng)軸應(yīng)變峰值(LVGLS),比較2組女性LVGLS的區(qū)別,分析LVGLS與年齡的相關(guān)性;分析2組孕婦在妊娠期LVGLS的變化規(guī)律。結(jié)果:未孕女性A組和B組的LVGLS差異有統(tǒng)計(jì)學(xué)意義,且LVGLS與年齡呈負(fù)相關(guān)(r=0.70)。A組孕婦在早孕期LVGLS先增強(qiáng),中晚孕期逐漸減弱;B組孕婦在整個(gè)妊娠期LVGLS均呈逐漸減弱趨勢(shì),2組之間的差異在28~36周時(shí)最大(P0.05)。妊娠期間,孕婦LVGLS與年齡呈正相關(guān),中晚孕期兩者的相關(guān)性較好。結(jié)論:未孕女性的LVGLS與年齡呈負(fù)相關(guān),妊娠后逐漸呈正相關(guān);年輕孕婦在早孕期LVGLS代償性增強(qiáng),高齡孕婦早孕期則無(wú)明顯代償性增強(qiáng),且在妊娠期間LVGLS持續(xù)性減弱。
[Abstract]:Aim: to evaluate the changes of global long axis strain of left ventricular myocardium during pregnancy in healthy pregnant women of different ages by using two dimensional speckle tracing imaging. Methods: healthy pregnant women and non-pregnant women were divided into two groups: group A (young group) and group B (aged 鈮，
