Analysis of in-hospital deaths from myocardial infarction after coronary care unit discharge

SummaryAnalysis of electrocardiograms tape-recorded from patients admitted to hospital with acute myocardial infarction revealed that the pattern of ventricular extrasystolic activity was not significantly different among those who subsequently developed ventricular fibrillation and those who did not. Episodes of ventricular fibrillation occurred predominantly within 4 hours from the start of infarction. Patients were 3 times less likely to survive an episode of ventricular fibrillation if they also had left ventricular failure than if this feature was absent. Management of episodes of ventricular fibrillation was compared in patients before and after the creation of a specially staffed and equipped coronary care unit. The success of electric shock as a treatment for ventricular fibrillation was similar before and after the creation of the coronary care unit. An attempt was made to determine which features in the management of ventricular fibrillation in this and in previously published series were associated with patient survival.

Electrocardiogram Ecg

Out of 284 patients admitted to the Coronary-Care Unit, 60 patients showed an acute monophasic injury pattern (M-Complex) on their initial electrocardiogram (ECG). There were 13 fatalities on the first day of myocardial infarction; 6 from the M-complex group. Three of these 6 patients died with cardiac rupture. The ECG features of these 3 patients were compared with the 3 non-rupture patients. A progressive increase in the elevated R-ST segment of the M-complex with an upward ‘pull’ of the R-ST junction, proved to be an ominous ECG sign of impending cardiac rupture in patients with protracted chest pain and persistent hypertenison. The 3 non-rupture patients remained in a hypotensive state from admission to the time of death. Atrioventricular block and A-V junctional tachycardia were the commonest rhythm disturbances in patients dying with cardiac rupture.

Coronary Care

The coronary care unit by Santa Izabel Hospital (Salvador, Bahia, Brazil) made a comparison of admitted patients with coronary disease cases admitted between two equivalent periods ranging from April through July in 2019 and 2020. There was a striking reduction in 2020 of cases of ST-elevation myocardial infarction (39%); non-ST elevation myocardial infarction (19%); and unstable angina pectoris (21%). This occurred in parallel with what happened in many parts of the world and hampered offering the best treatment strategy to these patients with an acute coronary syndrome such as invasive stratification and myocardial revascularization.
