Heart disease with the knowledge of pregnancy

To meet the pregnancy after fetal growth and development needs, Mother-to a series of changes in the circulatory system. The first is the gradual increase in blood volume in pregnancy of 32 to 34 weeks of pregnancy, not the peak of increased 40 a 50 percent, followed by the stroke of a gradual increase in pregnancy from 22 to 28 weeks of the peak, than when not pregnant An additional 20 to 30 percent. Due to the increase of uterine pregnancy advanced, diaphragm rose and heart shift. Right ventricular pressure increased, buckling great vessels, the heart of these changes have increased the burden. Postpartum, placental blood circulation stopped, uterine contraction of the large influx of blood circulation, as well as in the whole process of delivery of energy consumption, will increase the burden on the heart. Therefore, women have heart disease, heart dysfunction if, during pregnancy, labor or postpartum prone to heart failure, serious threat to mother and infant life.
Pregnant women with heart disease in most patients with rheumatic heart disease, followed by congenital heart disease. The sick can take heart pregnancy and childbirth, with little to the type of heart disease, and decided to decompensated heart function. According affordable physical activity, heart divided into four compensatory function. Level I: General physical activity unrestricted. 11: General physical activity slightly restricted, resting comfortable as usual, but in day-to-day physical activity or operation that is flu heartbeat short breath. Ill-class: General physical activity significantly restricted. When the rest were not sick, but less than some day-to-day activities of physical activity that is when there heartbeat, short breath. Class IV: any activity that is slightly feeling unwell, when there is still resting heart rate, dyspnea, with a clear heart failure phenomenon.
Cardiac Function Level I and 11 patients generally take pregnancy; Ill-class heart function, the incidence of maternal heart failure was significantly higher. Therefore, cardiac function Ill, it is not appropriate grade IV fertility. If contraceptive failure early abortion.
If decompensated heart function SHANG Jia, can continue to pregnancy, prenatal checks should on time, pay attention to sleep and rest, emotional stability, avoid excessive labor, restricting salt intake,various vitamins, and promptly correct anemia, and actively prevent and treat pregnancy poisoning of upper respiratory tract infection and to prevent heart failure caused premature labor and fetal distress. Preferably in the expected date of a two week hospital births. If caesarean section, preferably at the same time sterilization.
Postpartum contraceptive measures must be implemented. If a failure, the lack of oxygen can cause the uterus to contract, in premature birth, or because hypoxia can cause fetal distress.
