Heart disease during pregnancy

Pregnancy with heart disease is a serious obstetric comorbidity and the main cause of maternal death, with an incidence of 0.5-1.5%. Due to pregnancy, the uterus is enlarged, blood volume is increased, and the burden on the heart is aggravated. During labor, uterine and systemic skeletal muscle contraction causes a large amount of blood to flow to the heart, and the increase in post-partum circulating blood volume is likely to cause heart failure in the diseased heart. Pregnancy with heart disease, pregnancy-induced hypertension syndrome, and postpartum hemorrhage are also listed as the three major causes of maternal death. Rheumatic heart disease is the most common pregnancy with heart disease, accounting for about 80%, especially mitral valve stenosis. It is a serious pregnancy comorbidity, and the second largest maternal death in China. At the same time, due to chronic chronic hypoxia, fetal dysplasia and fetal distress are caused. Clinically, pregnancy with rheumatic heart disease is more common, and there are still congenital, pregnancy-induced hypertension heart disease, perinatal cardiomyopathy, and anemia heart disease. Whether a patient with a heart disease can safely survive pregnancy and childbirth depends on cardiac function, so this disease must be taken seriously.
