Pregnancy-Related Heart Issues: Essential Facts to Remember
Pregnancy is a time of significant physical changes, and these changes can sometimes put extra stress on the heart. Heart failure during pregnancy and postpartum can occur due to various reasons, and it's essential for pregnant women to be aware of the potential risks and symptoms.
One of the main causes of heart failure in the late stages of pregnancy or within five months postpartum is a condition called peripartum cardiomyopathy (PPCM). Risk factors for developing PPCM include obesity, multiparity (having given birth multiple times), gestational hypertension, diabetes mellitus, pre-eclampsia, and multiple pregnancies (twins, triplets).
Other possible causes of heart failure during pregnancy and postpartum include pre-existing heart conditions, such as coronary artery disease, high blood pressure, previous heart attacks, anomalies in heart structure, severe lung disease, congenital heart defects, and sleep apnea. Additionally, spontaneous coronary artery dissection (SCAD), which is more common postpartum and may cause acute heart issues, and pulmonary complications such as pulmonary edema, embolism, amniotic fluid embolism, or pneumonia, can precipitate cardiac failure.
Women with pre-existing heart conditions face increased risks for heart failure exacerbation during pregnancy. Demographic and clinical considerations, such as advanced maternal age (≥35 years), African American, American Indian, or Alaskan Native ethnicity, history of autoimmune or chronic infections, and prolonged use of beta-adrenergic agonists to prevent preterm labor, also matter in the development of heart failure during pregnancy and postpartum.
Another rare but serious pregnancy complication is amniotic fluid embolism (AFE), which can occur as early as the second trimester, during labor, a cesarean section, or shortly after birth. AFE can cause heart failure and death of the pregnant person and the fetus. Symptoms of AFE include trouble breathing, fluid in the lungs, low blood pressure, problems with blood clotting, rapid heart rate, sudden heart failure, change in the mental state, fetal distress, and cardiac arrest.
If you experience unusual symptoms during pregnancy that could indicate heart problems, it's crucial to contact a doctor immediately. To be diagnosed with AFE, a person must have sudden low blood pressure or cardiac arrest, low levels of oxygen in the blood, severe bleeding without other explanation, and all of the above occurring during labor, surgical delivery, or within 30 minutes of delivery.
In summary, heart failure in pregnancy and postpartum can be caused by PPCM triggered by risk factors like obesity, hypertension, pre-eclampsia, and diabetes, or by exacerbation of other cardiac or pulmonary conditions related to pregnancy. It's essential for pregnant women to be aware of the potential risks and symptoms and to seek medical advice if they experience any unusual symptoms. If you have pre-existing heart conditions, it's crucial to discuss your concerns with your healthcare provider before and during pregnancy to ensure the safety of both you and your baby.
