She and her colleagues found that women who deliver a baby before 37 weeks gestation in their first birth have a 40 percent greater risk of later heart disease, compared to women whose deliveries occurred on time — at or after 37 weeks.Feb 2, 2017
A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That's when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen. But between 6 1/2 to 7 weeks after gestation, a heartbeat can be better assessed.Sep 26, 2018
The healthcare provider will put a clear gel on your abdomen. The provider will press the transducer against your skin. The provider will move it around until he or she finds the fetal heartbeat. You will be able to hear the sound of the fetal heart rate with Doppler or an electronic monitor.
However, as blood volume increases, so does the amount of work the heart has to perform. A pregnant woman's heart has to exert twice as much effort to circulate the increased blood volume. During labor and delivery, blood pressure and heart rate can drastically change, putting additional strain on the heart muscle.
Because the heart works harder to deliver blood to the fetus, the risk of suffering a heart attack goes up during pregnancy, though it remains relatively low for most people. Complicating things is the fact that many women are waiting until they're older to have children.Feb 12, 2018
