The aim of this study was to investigate gender-specific short- and long-term mortalities after a first acute myocardial infarction (AMI) in patients with and without diabetes mellitus (DM). The study was based on 505 men and 196 women with DM and 1,327 men and 415 women without DM consecutively hospitalized with a first-ever AMI from January 1998 to December 2003 recruited from a population-based MI registry. Patients were followed until December 31, 2005 (median follow-up time 4.3 years). In men and women, no significantly independent association between DM and short-term mortality was observed. After multivariable adjustment odds ratios (95% confidence intervals [CIs]) for 28-day case fatality were 1.45 (95% CI 0.90 to 2.34) in men with DM compared to men without DM and 1.44 (95% CI 0.66 to 3.15) in women with DM compared to women without DM. Conversely, in 28-day AMI survivors DM was significantly associated with long-term mortality in age-adjusted analyses, in which men with DM had a hazard ratio (HR) of 1.57 (95% CI 1.18 to 2.10) for all-cause mortality compared to non-DM men; the corresponding HR in women with DM was 2.91 (95% CI 1.82 to 4.65). After multivariable adjustment the strong association in women with DM remained significant (HR 2.56, 95% CI 1.53 to 4.27); however, in men with DM it became borderline significant (HR 1.36, 95% CI 1.00 to 1.85). In conclusion, short-term mortality was not significantly increased in men and women with DM after a first-ever AMI, although estimates were relatively high, indicating a possible relation. However, long-term mortality was higher in patients with AMI and DM, particularly in women.
