Three variants of hemodynamic reaction to massive thromboembolism of the pulmonary artery are encountered--hyperkinetic, eukinetic, and hypokinetic. Their manifestations are determined by the patient's cardiovascular status at the onset of thromboembolism, the volume of the embolic obstruction, the degree of pulmonary hypertension, and the concomitant cardiopulmonary pathology. Effective treatment leading to marked reduction of pulmonary hypertension is conducive to increase in the proportion of the hyperkinetic type; ineffective thrombolysis, thrombosis of the inferior vena cava antiembolic filter, recurrent thromboembolism, and infarction pneumonia are the causes of diminished right-ventricular systolic function and reduced cardiac index, i. e. the formation of a hypokinetic type. |
