Haemodynamics in Acute Pulmonary Oedema in Coronary Patients

Abstract

Studies have been made of the haemodynamics in seven coronary patients with acute pulmonary oedema without shock. Five of the patients had acute myocardial infarction. The first examination was made 3–9 hours after the appearance of pulmonary oedema. During the examination evident signs of pulmonary congestion and dyspnoea could be demonstrated. The examination was made after treatment with oxygen, Cedilanide®, aminophyllin and Pethidin®. The second examination was made 8–13 days later, after all signs of pulmonary congestion had subsided. In the acute state tachycardia, reduced stroke volume and increased systematic blood pressure at a normal cardiac output were demonstrated. The difference between the two examinations was an increase of stroke volume, a reduction of the heart rate and systemic blood pressure, and an increase of the relation between stroke volume and central blood volume.
