对产褥期和妊娠晚期突然发生的心力衰竭,人们早已认识。通常把分娩前后3个月内发生的原因不明的心肌病称为产期前后心力衰竭(简称PPCF)或产期前后心肌病。在本病发生中,妊娠究竟起着特异性的病因学作用,还是在原有的亚临床心肌病过程中起着非特异性血液动力学应激作用,至今未明。这种亚临床心肌病,在妊娠前可能未被发现,或多年来一直无症状。 People have long been aware of the sudden onset of heart failure in the puerperium and in the third trimester of pregnancy. Usually before and after childbirth within 3 months of unexplained cardiomyopathy known as prenatal and post-heart failure (referred to as PPCF) or perinatal cardiomyopathy. In the occurrence of this disease, the pregnancy actually play a specific etiology, or in the original process of subclinical cardiomyopathy plays a non-specific hemodynamic stress, so far unknown. This subclinical cardiomyopathy may not be detected before pregnancy or asymptomatic for many years.
