Key result
Prior myocardial infarction only, compared with diabetes only, showed a similar risk of 25-year all-cause mortality (HR 0.97; 95% CI 0.92-1.03; P=0.32), but a higher risk of coronary mortality.
Why the study?
Does a history of MI compared to diabetes alone affect long-term mortality patterns in middle-aged men?
Cohort (n=9,434)
Does a history of MI compared to diabetes alone affect long-term mortality patterns in middle-aged men?
Hazard Ratio: 0.97 (95% CI 0.92–1.03)
p-value: p=.32
Diabetes and prior MI are similarly strong predictors of total mortality over 25 years, though prior MI predicts higher coronary mortality and diabetes predicts higher noncardiovascular mortality.

Supports equivalent long-term survival but distinct mortality drivers; leaves open etiology-specific prevention trials.
Olga Vaccaro (2004) conducted a cohort in Diabetes or prior myocardial infarction (n=9,434). Prior myocardial infarction only vs. Diabetes only was evaluated on all-cause mortality (HR 0.97, 95% CI 0.92-1.03, p=.32). Prior myocardial infarction only, compared with diabetes only, showed a similar risk of 25-year all-cause mortality (HR 0.97; 95% CI 0.92-1.03; P=0.32), but a higher risk of coronary mortality.
