AbstractEleven percent of 905 consecutive patients with acute myocardial infarction admitted to the coronary care unit at Duke University Medical Center experienced cardiac arrest. Subgroups of patients at high and low risk for cardiac arrest were identified. Cardiac arrest was experienced by 17 percent of patients with signs of heart failure on admission but by only 3 percent of patients without diabetes mellitus, prior myocardial infarction or heart failure by history or on admission. Only 59 percent of patients with cardiac arrest survived hospitalization compared with 88 percent of those without cardiac arrest. Long-term survival for the 765 hospital survivors was significantly greater in the group without than in the group with arrest at each yearly interval from 1 through 5 years; the 2 year survival rate was 50 and 77 percent, respectively, in these two groups. Many of the deaths among the hospital survivors occurred in patients with signs of heart failure during hospitalization. Among 668 hospital survivors who had mild or no heart failure during hospitalization, cardiac arrest continued to be a significant predictor of mortality. The mode of death among hospital survivors did not differ in the groups with and without cardiac arrest; for example, the incidence rate of sudden death in the two groups was 44 and 37 per cent, respectively. In light of recent reports suggesting that the prophylactic use of antiarrhythmic agents can virtually eliminate virtually fibrillation during the hospital phase of acute myocardial infarction, we contend that such use may substantially reduce both long-term and hospital mortality after acute myocardial infarction.
