There is a risk of cardiovascular diseases during pregnancy. It is a challenge to treat such patients without affecting the lives of mother and child. Even in normal patients during pregnancy dramatic changes occurring in physiology may affect the cardiovascular system too. These include an increase in plasma volume by 50%, an increase in resting pulse by 17%, and an increase in cardiac output by 50%. After delivery, the heart rate normalizes within 10 days; by 3 months postpartum, stroke volume, cardiac output, and systemic vascular resistance return to the pre-pregnancy state. Cardiologists working in tandem with obstetrics, gynecologists, and pediatrics should provide the best treatment interventions.
