[Functional state of the left ventricle during diastole in patients with a history of myocardial infarction].
A total of 36 survivors of myocardial infarction and 20 normal controls were examined using echo- and polycardiographic techniques. The duration of left ventricular isovolumetric relaxation was shown to increase at early stages of circulatory insufficiency, and decrease at later stages. At earlier stages of circulatory insufficiency, left ventricular blood filling post-infarction patients becomes discordinated, as reflected in enhanced blood filling during the slow-filling and atrial systolic phases and reduced blood filling during the fast-filling phase, which is supposed to be of compensatory nature and contribute to the Frank--Starling effect. The shape of the left ventricle is abnormally changed during isovolumetric relaxation and contraction phases irrespective of the severity of circulatory insufficiency.
