title: [A method of quantitative evaluation of left-ventricular functional reserve in patients with heart aneurysm].
abstract: Twenty-four patients with postinfarction aneurysms of the heart and 9 patients with chest pains were investigated in order to assess the value of left-ventricular reserve parameters, proposed by the authors, i. e. the ratio between the percentage of change in ejection time and diastolic elasticity in the course of isometric stress and the increment at arterial blood pressure test. These parameters are shown to be more valuable for the assessment of left-ventricular function, as compared to conventional ventriculographic and intraventricular pressure parameters, measured at rest. The changes in ejection fraction and diastolic elasticity at isometric stress are a fairly reliable signal that the resection of heart aneurysm may be contraindicated.
