[Real oxygen transport in myocardial infarct patients in relation to the central hemodynamic type]

Real oxygen transport (ROT) was investigated in relation to central hemodynamic type in 41 patients on Days 1,2, 3,5, 10 of myocardial infarction. In patients with normodynamic central hemodynamics, ROT gradually goes down by Day 5 of the disease, mostly due to a decrease in blood oxygen capacity (BOC), and eventually returns to normal. The hyperdynamic type of central hemodynamics is associated with significant ROT variation, its increase in the presence of the hyperdynamic syndrome alternating with declines at other times. The hypodynamic type with clinical signs of congestive heart failure is associated with a progressive ROT decrease, mostly due to reduced cardiac index as well as moderately decreased BOC. Providing a link between the circulatory and respiratory systems of the body, ROT is an informative parameter for the assessment of the severity of heart failure in myocardial infarction.
