title: [Assessment of myocardial contractility by the sector scanning of myocardial infarct patients].
abstract: A comparative assessment of left-ventricular myocardial contractility in patients with myocardial infarction was made using sector scanning and ventriculographic techniques. Eight patients were investigated within 2-4 hours of the infarction, and twenty patients, on days 20-25 of the disease. Ultimate diastolic, ultimate systolic and stroke volumes were calculated, as was the expulsion fraction, using the mono- and biplane method and modified formula 5/6 AL. Ventriculography was the testing method. Sector scanning is shown to be one of the most informative methods of myocardial contractility assessment in patients with myocardial infarction; the formula 5/6 AL appears to yield the best information when left-ventricular volumes are computed.
