title: [Graded volume loading in the diagnosis of early heart failure among myocardial infarct patients].
abstract: The method of graded physical exercise with the plotting of the functional curves and calculating of the functional coefficient (FC) was used in the study. No relationship was detected between the initial level of the cardiac output and the direction of the functional curve. A negative FC was more frequently recorded in patients with Q-index 25.
