[The prognostic value of continuously measured pulmonary artery pressure in recent myocardial infarct].

Enddiastolic pulmonary artery pressure (PAEDP) was measured continuously in 100 patients with acute transmural myocardial infarction, beginning on admission to the CCU and lasting till the 3rd, 4th or 5th day. The PAEDPs of the first day were averaged and on this basis the patients were divided into three groups. Mortality in Group I (41 patients with PAEDP below 12 mm Hg) was 4.9%, in Group II (43 patients with PAEDP of 12-20 mm Hg) 16.3%, and in Group III (16 patients with PAEDP above 20 mm Hg) 43.8%. Use of additional hemodynamic parameters such as cardiac output, cardiac index, and cardiac work index increased prognostic precision for patients in the acute stage. However, they did not improve prognostic precision on fatal outcome in the post-acute stage. Bicycle exercise stress tests carried out several months later with simultaneous evaluation of hemodynamics (PAEDP) showed a good suitability for rehabilitation in Group I and in 58% of the patients in Group II. The other 42% had a significant rise in pulmonary artery pressure, could not undergo stress, and, in our view, are suitable for rehabilitation only in exceptional cases.
