Acute pulmonary edema due to ischemic heart disease without accompanying myocardial infarction. Natural history and clinical profile

The natural history of acute cardiogenic pulmonary edema was studied in a group of patients who did not have acute myocardial infarction, cardiomyopathy, or valvular heart disease. Most of these patients had coronary artery disease. Cardiac catheterization in selected patients showed depressed contractility in some with segmental abnormalities. In the group older than 70 years, this carried a 70 percent two-year mortality rate. It is important to approach patients with this syndrome vigorously, both diagnostically and therapeutically. Acute, reversible segmental ischemia may be responsible for this syndrome and may respond to measures designed to prevent recurrent ischemia.
