| 摘 要： | 目的应用斑点追踪技术定量分析正常成人右室局域心肌形变能力,并探讨年龄对形变能力的影响。方法应用斑点追踪成像技术测量75例健康成人的右室游离壁各节段心肌应变及应变率,在二维应变的模式下于心尖四腔观上勾画右室心内膜面,测量并记录右室游离壁基底段、中段及心尖段收缩期峰值应变(ε)、收缩期峰值应变率(SRs)、舒张早期峰值应变率(SRe)、舒张晚期峰值应变率(SRa)及舒张早期峰值应变率与舒张晚期峰值应变率的比值(SRe/SRa),比较各节段间变化规律及各指标随年龄增加的变化规律。结果右室基底段ε、SRs、SRe、SRa显著高于心尖段,SRs、SRe高于中段,SRe/SRa各节段间无差异。SRe随年龄增长而轻度减低,与年龄呈负相关(r=-0.229～-0.301,P<0.05),SRa随年龄增长而增加,与年龄呈显著正相关(r=0.438～0.525,P<0.01),SRe/SRa随年龄增长而明显减低,与年龄呈显著负相关(r=-0.466～-0.614,P<0.01)。结论斑点追踪技术可以准确、客观的评估右室长轴心肌收缩期、舒张期形变的能力。右室舒张期形变能力随年龄增加而减低。
