Early symptoms of heart disease during pregnancy

Heart disease during pregnancy is difficult to treat, and treatment can easily affect the fetus. So what are the earliest symptoms of heart disease during pregnancy?

In pregnant patients with heart disease, a complex series of changes occur in the mother's body from the start of pregnancy to the weeks after delivery. Cardiac output increased from the 10th to 12th week of pregnancy, and peaked at the 20th to 24th week of pregnancy in the supine position, which was 30-40% higher than that of non-pregnant women at rest, and returned to normal two weeks after delivery. The heart rate of pregnant women is faster than that of non-pregnant women, increasing by about ten beats per minute near term and even more when pregnant with twins.

Heart disease during pregnancy can lead to embolism: the blood during pregnancy is in a hypercoagulable state, and the increased venous pressure and venous blood stagnation associated with heart disease are prone to embolism. The thrombus may originate in the pelvis, cause a pulmonary embolism, increase pressure in the pulmonary circulation, which can cause pulmonary edema, or reverse a left-to-right shunt to a right-to-left shunt. In the case of congenital heart disease in which the left and right heart chambers are connected, the thrombus may pass through the defect and cause peripheral arterial embolism.

Why do I get heart disease during pregnancy

Heart disease is not only congenital, but may also have heart disease during pregnancy, so why do you have heart disease during pregnancy?

Because women's physical and mental burden will increase after pregnancy, and some female friends have a lot of psychological pressure after pregnancy, or are affected by environmental factors, genetic factors, physical fitness and other factors, which will lead to women's heart disease during pregnancy. Pregnancy with heart disease is a serious obstetric complication and one of the leading causes of maternal death. There are two causes of heart disease during pregnancy, one is heart disease that existed before pregnancy, such as congenital heart disease, rheumatic heart disease, and the other is new heart disease during pregnancy. The increase in the amount increases the burden on the heart and the contraction of the uterus and skeletal muscles of the whole body during childbirth, so that a large amount of blood flows to the heart.

Or postpartum circulating blood volume increases, leading to primary heart failure. For example, hypertensive heart disease is caused by elevated blood pressure during pregnancy and poor long-term blood pressure control, leading to heart failure or perinatal cardiomyopathy. Or intrauterine dysplasia and fetal distress due to long-term chronic hypoxia.

Pregnant women with bradycardia will suffer from hypoxia in pregnancy

During pregnancy, the heartbeat is generally faster, but some pregnant women have bradycardia, so will pregnant women with bradycardia suffer from hypoxia during pregnancy?

Pregnant women with bradycardia will have children with hypoxia, which varies from person to person. In general, a normal heart rate is 60 to 100 beats. If the heart rate is in this state for a long time, there is still a low sinus heart rate. This has a lot to do with physical diet. It can be adjusted by taking some nourishing qi and blood drugs. During pregnancy, pay attention to more rest and ensure adequate sleep time, which is more conducive to heart health.

Generally speaking, the heart rate of pregnant women will be faster, generally to increase the supply of blood flow, so the heart rate needs to increase about 10 times per minute than before pregnancy. However, if the physique of the pregnant woman is very good and the heart rate is relatively slow before pregnancy, there is generally no need to deal with it, and it will not have any effect on the fetus. Pay attention to reasonable nutrition, a balanced diet, pay attention to rest, and ensure adequate sleep time, which is more conducive to health. The best thing to do is to have an ultrasound of the heart to see what's going on.
