Key result
In-hospital sudden death after coronary care unit discharge in acute myocardial infarction patients was associated with having three or more high-risk factors compared to matched controls (77% vs 3%).

What are the clinical characteristics associated with in-hospital sudden death after coronary care unit discharge in patients with acute myocardial infarction?
Absolute Event Rate: 77% vs 3%
In-hospital sudden death after CCU discharge in AMI patients is strongly associated with prolonged CCU stay, arrhythmias, anterior MI, and the presence of multiple high-risk factors.
Supports post-CCU risk stratification in AMI; leaves open whether interventions reduce sudden death.
In a retrospective analysis of in-hospital sudden death among patients with acute myocardial infarction, nine of 48 (18.7%) in-hospital deaths after discharge from the coronary care unit were judged "sudden." This group had a significantly prolonged coronary care unit course, a higher incidence of supraventricular and ventricular arrhythmias, and a noticeable incidence of anterior wall myocardial infarction as compared with those of a matched infarct control group. Seventy-seven percent of the sudden-death group had three or more concomitant highrisk factors as compared with only 3% of a matched control group.

Thomas B. Graboys (1975) conducted a case-control in Acute myocardial infarction. In-hospital sudden death after coronary care unit discharge vs. Matched infarct control group was evaluated on Presence of three or more concomitant high-risk factors. In-hospital sudden death after coronary care unit discharge in acute myocardial infarction patients was associated with having three or more high-risk factors compared to matched controls (77% vs 3%).
