During pregnancy, blood volume increases by 30 to 50 percent. The amount of blood the heart pumps each minute also increases by 30 to 50 percent, and heart rate increases as well. These changes cause the heart to work harder, as do labor and delivery. This issue covers diagnosis and treatment of cardiac symptoms and cardiac emergencies during pregnancy.
