[Hemodynamic control of graded isometric exercise in patients with acute myocardial infarction with hypokinetic type of circulation and stage I heart failure].
A hypokinetic pattern of circulation (HKC) was revealed in 53 (63.1%) out of 84 patients with acute myocardial infarction (AMI) free of congestive cardiac insufficiency at rest examined upon discharge from hospital. Resting ++rheography evidence for pumping and constrictive cardiac functions fails to recognize CCI in stage I. A hemodynamic criterion of CCI was inadequate loading which implies no increment or reduction in the level reached at graded foot isometric exercise, in a number of indices such as cardiac index, hemodynamic performance of the heart, stroke and integral indices. The incidence of CCI stage I demonstrated by AMI patients with HKC was 64.2% (30.2% in period A and 34.0% in period B). HKC incidence in AMI patients without CCI outnumbered that in normal subjects by 30.6%.
