How does pregnancy affect the heart?
Pregnancy stresses your heart and circulatory system. During pregnancy, your blood volume increases by 30 to 50 percent to nourish your growing baby, your heart pumps more blood each minute and your heart rate increases.
Labor and delivery add to your heart's workload, too. During labor — particularly when you push — you'll have abrupt changes in blood flow and pressure. It takes several weeks after delivery for the stresses on the heart to return to the levels they were before you became pregnant.
