Incidence of circulatory arrest in patients with acute myocardial infarction in coronary unit. Mechanism of their genesis and factors conditioning successful resuscitation.

The incidence, circumstances, and mechanism of development of cardiac arrest in 786 patients with myocardial infarction treated at a coronary care unit within a five-year period were studied and clinical factors are analysed with respect to success of resuscitation. One or more episodes of cardiac arrest occurred in a total of 156 patients (19.8%). Of these, 25 (16.0%) were successfully resuscitated and 131 (84.0%) died. At the clinical ward where the patients had been transferred after the acute stage, cardiac arrest occurred in additional 22 patients, of whom two were successfully resuscitated. Thus, the total number of successfully resuscitated patients throughout the five-year period was twenty-seven. The results of resuscitation were poorer in elderly patients, in those with anterior infarction, and above all in patients with severe symptoms of mechanical heart failure. Anamnestic factors (chronic angina pectoris, previous myocardial infarction, hypertension, diabetes mellitus, ischaemic disease of the lower limbs) were not significantly associated with the results of resuscitation. Primary ventricular fibrillation was the principal mechanism of cardiac arrest in 24 of the 27 patients successfully resuscitated, and its total incidence in the investigated group was 3%. The prognosis of resuscitation in patients with primary ventricular fibrillation was very good, and in all of them the resuscitation was successful and permanent.

Hospital mortality in patients with acute myocardial infarction: five-year experience.

Mortality during the hospitalization period was analyzed in a sample of 786 patients with acute myocardial infarction [AMI], admitted to the coronary care unit within a five-year period from a catchment area of 200 000 urban inhabitants. The total mortality during the hospitalization period amounted to 19.2%. The prognostic significance of certain clinically meaningful phenomena was appraised on the basis of their association to the mortality. It was demonstrated that the factors decisive for the prognosis of a patient with AMI are age, previous myocardial infarction, extent and localization of the ischaemic lesion apparent from the ECG tracing, and, in addition, presence of the atrioventricular and intraventricular conduction defects, especially if combined with anterior myocardial infarction. Patients with a high cumulation of these prognostic factors exhibited severe signs of mechanical heart failure, which is the mechanism of death in practically all of the deceased patients under the present possibilities of treatment.
