Forty-two consecutive patients with non-Q-wave acute myocardial infarction (AMI) and 40 consecutive patients with transmural AMI were comparatively examined by equilibrium gated radionuclide angiography (ERNA) to assess prevalence and prognostic value of left ventricular dysfunction in non-Q-wave AMI. Left ventricular ejection (LVEF) was generally preserved both in anterior and inferior non-Q-wave infarctions and sharply reduced only in anterior transmural infarctions. ERNA cannot assist in identifying any subgroup of patients with non-Q-wave AMI at risk of major complications other than left ventricular failure because they may develop such complications in spite of a normal LVEF.

Zusammenfassung

42 Patienten mit akutem, nichttransmuralem Myokardinfarkt (fehlende Q-Welle im EKG) und 40 Patienten mit transmuralem Myokardinfarkt (Q-Welle im EKG) wurden vergleichend mit der Äquilibrium-Radionuklid-Ventrikulographie (ÄRNV) zur Erfassung von Prävalenz und Vorhersagewert einer linksventrikulären Dysfunktion bei nichttransmuralen Infarkten untersucht. Die linksventrikuläre Auswurffraktion war im allgemeinen sowohl bei nichttransmuralen Vorderwandals auch Hinterwandinfarkten erhalten. Eine deutliche Reduktion trat nur bei transmuralen Vorderwandinfarkten auf. Die globale Auswurffraktion, bestimmt mit der ÄRNV, erlaubt keine Unterscheidung von Patienten mit nichttransmuralem Infarkt bzgl. der Erwartungswahrscheinlichkeit möglicher Komplikationen mit Ausnahme des Linksherzversagens. Andere Komplikationen können sich entwickeln, obwohl die Auswurffraktion initial nicht eingeschränkt ist.
