“…4 From a cardiovascular standpoint, during pregnancy, afterload is increased because of increased systemic vascular resistance (SVR), preload is decreased because of diminished volume expansion, and intravascular fluid shifts into third spaces (especially the lungs) because of endothelial injury related to hypertension. 5 Prolonged, uncontrolled hypertension puts the patient at increased risk of aortic or coronary artery dissection 6,7 and PPCM 8 (both are discussed later in this article). Blunted volume expansion, 9 in addition to renal artery vasospasm, 10 significantly decreases renal flow and glomerular filtration rate, causing impressive oliguria.…”
