This article examines the pathophysiology, diagnosis, treatment, and o
utcome of acute cardiogenic pulmonary edema, as well as re-expansion,
high-altitude, postobstructive, and neurogenic pulmonary edemas. Acute
cardiogenic pulmonary edema most commonly presents as a consequence o
f congestive heart failure. The other important causes are acute myoca
rdial dysfunction, documented myocardial infarction, postoperative car
diac dysfunction, and pulmonary hypertension. All these entities have
in common increased pulmonary vascular pressures that lead to pulmonar
y edema.
