摘　　要：目的探讨声学造影评价老年人左室收缩功能的价值及安全性。方法观察76例至少有2个节段心内膜显示不清的60岁以上患者,经静脉注射声诺维声学造影剂后,分析左室内膜边界显影改善效果,采用双平面Simpson法测量造影剂应用前、后的左室射血分数。结果声学造影前后的心内膜边界显影评分分别为(14.06±1.58)分、(21.38±1.66)分,差异有统计学意义(P<0.001);造影前后的左室射血分数分别为(52.66±5.75)%、(64.37±4.58)%,差异有统计学意义(P=0.000),且所有患者均未出现头晕、心悸、胸痛等不适。结论声学造影用于评价60岁以上人群左室收缩功能安全且有效。Objective To explore the value and safety of contrast echocardiography in the evaluation of left ventricular systolic function in elderly patients. Methods Seventy-six patients with above 60-year-old,whose left ventricular endocardial borders were not detected in at least two segments,were injected SonoVue ultrasound contrast agent. Echocardiography was evaluated for the LV endocardial border delineation,and LVEF was measured before and after contrast echocardiography by Simpson method. Results The score of LV endocardial border imaging before and after contrast echocardiography was 14.06 ±1.58 and 21.38 ±1.66,respectively（P 0.001）. Contrast echocardiography was superior to tissue harmonic imaging for LVEF measurement,which were（52.66 ±5.75）% vs.（64.37 ±4.58）%（P =0.000）. No patients had discomfort such as dizziness,palpitations and chest pain. Conclusion The evaluation of left ventricular systolic function using contrast echocardiography in elderly patients over the age of 60 is effective and safe.
