[Disorders of hemodynamics and pulmonary gas exchange in the acute period of myocardial infarct].
In 40 patients with massive myocardial infarction, the central hemodynamics was examined by probing the right-sided chambers of the heart and the pulmonary artery. The cardiac output was measured by thermodilution. The gas exchange (respiratory minute volume, capnography, gas analysis of arterial and mixed venous blood) was explored. Arterial hypoxemia was found to be associated with increased intrapulmonary blood shunting in patients with acute myocardial infarction complicated by congestive heart failure. Deterioration of arterial hypoxemia was promoted by a combination of increased overall pulmonary shunting and decreased residual venous oxygenation. Abnormalities in the ventilation-perfusion relations are of great importance.
