一、急性肺原性心脏病大或广泛的肺动脉栓塞,可使肺动脉大部分阻塞而导致心排血量锐减,肺动脉压力急剧增高及急性右心衰竭。此称急性肺原性心脏病。该病在国内相对少见,但误诊率很高。大的肺动脉栓塞可引起猝死,小的肺动脉栓塞可无明显临床表现,因此生前诊断是很不容易的。本病的诊断关键是能否了解可能产生肺栓塞的临床背景或诱因。如慢性器质性心脏病伴有房颤,近期做过较大的胸腹部手术,年 First, acute pulmonary heart disease Large or extensive pulmonary embolism, most of the pulmonary artery obstruction can lead to a sharp drop in cardiac output, pulmonary hypertension and acute acute heart failure increased sharply.
