In second stage of labor, cardiac output increases significantly due to vigorous expulsive effort. (Ueland & Metcalfe 1975). After delivery, removal of placenta leads to increase in systemic vascular resistance. Blood loss during labor is a stress on the heart. Equally important is the fact that several hormonal stimuli that occur during pregnancy are receding during postpartum, leading to return of blood volume, hematocrit and cardiac output to pre-conception levels. 3. Effect of pregnancy on ASD Hemodynamic changes outlined above will affect the hemodynamics of ASD.
Since placenta offers very low vascular resistance, maternal systemic vascular resistance decreases. A reduction in left ventricular afterload occurs (Metcalfe & Ueland 1974). A corresponding increase in cardiac output occurs during the same period, keeping blood pressure stable in spite of the reduction in afterload. Overall, circulatory changes can be summarized as follows: Increase in stroke volume by 1825% with heart rate increase by 20%. Net effect of this is a 30-50% increase in cardiac output.
