随着孕周的发展,孕妇的心脏结构,以及心脏功能都会发生一系列适应性变化。正常孕妇随着孕周的发展,其心脏的泵血功能会出现增强,心率明显加快,心输血量显著增加,同时其舒张功能,以及相应的结构也发生着变化。当孕妇在怀孕阶段,自身出现孕期并发症,比如合并高血压等,会导致胎儿的生长受到限制,当孕妇患有心脏疾病,或为双胎妊娠的时候,其心脏的功能都会出现不同变化。当孕妇在妊娠期出现合并心脏疾病时,由于所患的心脏疾病的类型不同,所导致的妊娠结局也不尽相同。妊娠早期合并不同疾病的孕妇,其心脏功能已经发生相应改变。
With the development of gestational age, a series of adaptive changes occur in the heart structure of pregnant women as well as cardiac function. Normal pregnant women with the development of gestational age, the heart pump blood function will increase, significantly accelerated heart rate, cardiac blood volume increased significantly, while its diastolic function, and the corresponding structure also changed. When pregnant women in pregnancy stage, their own complications during pregnancy, such as hypertension, will lead to fetal growth is limited, when pregnant women suffering from heart disease, or twin pregnancy, the heart’s function will have different changes. When pregnant women with combined heart disease during pregnancy, due to the type of heart disease caused by different, resulting in pregnancy outcomes are not the same. Pregnant women with different diseases in early pregnancy have a corresponding change in their cardiac function.
