[Site and type of acute myocardial infarct in relation to myocardial infarct size--dynamics of global ejection fraction in acute myocardial infarct].
By the ejection fraction global (EFg) statements concerning the remaining function of the myocardium in acute myocardial infarction and thus individually concerning the prognosis (classification of risk groups) become possible. For the valuation of the dynamics of the EFg in a period up to 6 months after an acute myocardial infarction the EFg was multifariously controlled. Only patients with first myocardial infarction in localization on the anterior wall and Q-wave showed a significant dynamics of the EFg between the measurements acute and third week as well as acute and 6th month (absolutely 5.2%). --In re-infarction/Q-wave this could be confirmed also for the localization of the posterior wall in the period acute till third week. For the localization on anterior and posterior wall a dynamics of the EFg could also be calculated for the period acute and 6th month. Thereby the absolute increase of the EFg was between 4.0 and 4.6%. The dynamics of the EFg in the region of the anterior wall was 5.2% for the first infarction and only 4% for the reinfarction. Thus it is below the dynamics of the EFg in an effective thrombolytic therapy.
