  • Renovascular hypertension accounts for 1% to 2% of cases of hypertension and is the most common secondary form of the disease. The pathophysiology of renovascular hypertension relates to a hemodynamically significant stenosis of the renal artery. The consequent decrease in renal blood flow stimulates an increase in renin release from the underperfused kidney and subsequently...

  • The initial evaluation of a patient with hypertension should include a thorough history and physical examination and limited laboratory studies.

  • The pulmonary vasculature is a high-capacity, low-resis-tance system, and it functions under relatively low pressure. The normal pulmonary arterial systolic and mean pressures are less than 30 mm Hg and less than 20 mm Hg, respectively. Diseases of this sys-tem impair gas exchange across the pulmonary alveoli and result in an increase in pulmonary arterial...
