[Behavior of pulmonary artery pressure during ergometer stress in sitting position in patients with ischemic heart disease].
In 40 patients (33 men, 7 women) at the age of 62 +/- 9 years with acute definitive myocardial infarction after the end of the rehabilitation phase I a Pulmoflex catheter was introduced through an arm vein into the pulmonary artery. After having measured the rest values in lying position the systolic, diastolic, end-diastolic and mean pressure of the pulmonary artery in sitting position were established. After this the continuous pressure determination during increasing ergometer loading in sitting position was performed. At the transition into sitting position the systolic pressure of the pulmonary artery decreased by on an average 4 Torr, while the diastolic and end-diastolic values remained constant. In the trend the mean value decreased by 2 Torr. During the ergometry the pressure values could be recorded in good quality. With increasing load all measuring values continuously increased. Thus it was possible to determine the blood pressure in the pulmonary artery during the ergometer load in the physiological and for the practice more evident sitting position.
