摘要 目的探讨围绝经期与绝经早期妇女心脏左室功能的组织追踪成像(TTI)、应变率成像(SRI)特点。方法选择绝经期女性137例,其中围绝经期组69例,绝经早期组68例;均行常规超声心动图检测,测量E、A峰血流速度,计算E/A;采用TTI、SRI测量后间隔与侧壁、下壁与前壁、后壁与前间隔的二尖瓣环处收缩期峰值位移(D)、平均位移(mean D)及心室收缩期、心室舒张早期、心房收缩期心肌的峰值应变率(SRs、SRe、SRa)、SRe/SRa。结果与围绝经期组比较,绝经早期组女性E值、E/A降低(P均<0.01),左室各壁二尖瓣环处SRs、SRe/SRa降低(P均<0.05),左室多数室壁二尖瓣环处D值和mean D值降低(P<0.05或<0.01)。结论绝经早期妇女左室舒缩功能较围绝经期妇女受损严重,且其心肌局部收缩和舒张功能变化早于心脏整体功能变化。
