[Early and late ventricular fibrillation in myocardial infarction. Prognostic value of clinical and echocardiographic indicators].
Our studies were aimed at evaluating the prognostic value of certain clinical and echocardiographic parameters as well as cardiac arrhythmias in patients with acute myocardial infarction complicated by ventricular fibrillation. The studies comprised 66 patients with previous ventricular fibrillation selected out of 637 patients undergoing treatment after recent myocardial infarction at the Clinic of Cardiology, Institute of Cardiology, Medical Academy, Poznań. The group included 51 males and 15 females aged 30-83, mean age 68. Anterior and/or lateral infarction were diagnosed in 44 patients (67%) whereas inferior and/or posterior infarction in 22 patients (33%). Fifty-eight patients (88%) had transmural infarction. The 2D and M-mode echocardiographic examinations and 24-hour Holter monitoring were performed in all patients. The group of patients resuscitated successfully was compared to the group of deceased patients. The observation period ranged from 1 to 7 years, mean 4 years. The analysis indicated that high mortality of patients with late ventricular fibrillation results from an extensive myocardial infarction and severe ventricular contractility disorders. In patients with late ventricular fibrillation, the main prognostic factor proves to be congestive heart failure and intraventricular conduction disorders with the fascicular and/or bundle-branch block types.
