“…The five-year mortality rate of 40% in the present study, comprising patients with a mean age of 65 years at the time of the infarction, is comparable to findings in other studies (5); mortality was highest during the first follow-up year. As expected, the relative death risks were very high among patients below 60 years of age; relative risk 14.7 during the first year after the AMI.…”

ABSTRACT. 1329 patients were discharged alive after acute myocardial infarction initially treated in a CCU. In a five‐year follow‐up, 537 (40%) of the patients died. Routine data registered uniformly during the CCU period showed that, apart from age, the most important factors regarding long‐term prognosis in general were previous ischaemic heart disease and direct or indirect signs of heart failure registered in the CCU. The possibilities to predict sudden death (130 patients died within 2 hours of onset of final symptoms during the follow‐up period) were small, although a definite dominance of this mode of death was noted in patients below 60 years of age. The clinical profile of the majority of the 134 patients who died during the first half‐year was distinguished by a history of prior myocardial infarction and signs of left heart failure during the CCU stay. However, in a significant number of patients dying early after discharge, none of the ordinary unfavourable prognostic signs had been registered.

“…The method presented by Chiang (1) enables us to make the desired distinctions and to study competing risks which are of interest when investigating late prognosis and the impact of recurrences of illness. The present 5-year survival rate of 56% among initial survivors of AM1 is in accordance with findings in other studies (3,7). However, precise comparisons are difficult to make because of differences in the composition of patient groups.…”

“…Follow-up studies of initial survivors of acute myocardial infarction (AMI) have shown that 75-94% of the patients subsequently die from a manifestation of their ischaemic heart disease (IHD) (2,3,6). Among the IHD deaths it is sudden death, variously defined, which has attracted most interest, as it has been assumed to be caused by ventricular arrhythmias which might be avoided by antiarrhythmic prophylaxis.…”

The 5-year pattern of mortality among 475 immediate survivors of acute myocardial infarction (AMI) (mean age 65 years on entry) is described by a life-table technique. The risk of death was highest during the early part of the follow-up. After 3 4 years, the prognostic influence of the AM1 seemed to be overshadowed by the age effect. Special attention was paid to the incidence of sudden death, a fictive elimination of which was shown to reduce the risk of death by 9-22% during the different years of the investigation period. The absolute number of sudden deaths was highest during the early part of the follow-up period but the relative importance of this mode of death was approximately the same during the entire 5-year period after the AMI.

“…The improved treatment of AMI was demonstrated not only by increased long-term survival, but also by the cause of death of patients dying during the follow-up period. A Danish study (29) reported the eight-year survival of AMI patients discharged alive in 1963. This study found a five-year survival of 53.7%, and after eight years of follow-up, AMI and other heart diseases accounted for 74.4% of deaths.…”
