Abstract

The reproducibility of several parameters during exercise stress testing has been demonstrated, but there is little information regarding the reproducibility of some hemodynamic variables in invasive studies, particularly in patients with recent myocardial infarction (MI). 18 males with MI, aged 38-66 yr (mean 54), 24-45 days (mean 33) after the acute event underwent isometric handgrip at 30% of maximal voluntary contraction for 3 minutes and maximal symptom-limited bicycle ergometric test in the supine position. One hour later the tests were repeated. Heart rate, blood pressure, O 2 uptake, left and right ventricular filling pressures, cardiac output and ECG were evaluated. Comparison of the resting data showed that mean right atrial pressure (RAP) and pulmonary wedge pressure (PWP) were lower before the second ergometric test (E2) (p20 mmHG (abnormal, 10 patients). The variations of the hemodynamic variables mentioned above occurred only in group B, while E1 and E2 were reproducible in group A. The electrocardiographic evidence of the infarct size (NQ) was identical in both groups and no QRS significant modifications occurred during exercise. During E1, ST segment changes were observed in 8 patients, during E2, ST segment shift was similar in 3 patients, lesser in 1 and greater in 4. During the handgrip exercise, lower values of RAP (p
