1、ESC 2008 心力衰竭：新的定义,心力衰竭是一种临床综合征，患者有以下三类特点：典型症状（呼吸困难、乏力或疲乏、踝部肿胀）典型体征（心动过速、呼吸急促、肺部啰音、胸腔积液、颈静脉压力升高、外周水肿、肝大）休息时心脏结构或功能异常客观证据（心脏增大、第三心音、心杂音、超声心动图异常、BNP增高）,上海瑞金医院施仲伟,Dickstein K,et al.Eur Heart J 2008,29:2388,Two-dimensional echocardiography with Doppler should be performed during initial evaluation of pa
