How pregnancy affects the heart

When you’re pregnant, your heart has to work harder because it has to pump 40% more blood to other organs. Blood vessels dilate to increase blood flow, and blood pressure gradually decreases. In order to avoid bleeding during childbirth, the body’s natural mechanism will make the blood more likely to clot, and the blood’s ability to coagulate will be enhanced to reduce the chance of massive bleeding during childbirth. The normal human heart will automatically adjust to adapt to these changes, but for patients with congenital heart disease, the stress on the heart is like running on a treadmill non-stop for nine months.

How to prepare before pregnancy?

If pregnant patients with heart disease want to become pregnant, they can plan as early as possible, fully discuss with medical experts and physicians, and have a professional team perform a pre-pregnancy assessment to determine whether you are suitable for pregnancy. The main assessment will look at your clinical condition and consider your ability to cope with daily activities. If you are able to work and carry out normal activities, the birth process should go smoothly, but if your daily activities are limited, experts must use different metrics to determine whether you are suitable for pregnancy and childbirth.

Doctors, experts and pharmacists will prescribe the safest and most appropriate dosage prescription for you. You must take the medicine according to the doctor’s instructions, and be careful not to stop taking the medicine without permission or change the dosage on your own.
