The Impact of Type 2 Diabetes Mellitus on Long-Term Prognosis in Patients of Different Ages with Myocardial Infarction

The objective of the study was to assess the impact of DM2 at baseline on long-term mortality after acute myocardial infarction (MI) among different age groups.

The data were taken from: “Register of Acute Myocardial Infarction.” A total of 862 patients were followed for five years after acute myocardial infarction.

The primary endpoint was death from any cause.

The patients were categorized into 2 groups based on their ages: group 1—comprised patients older than working age (n=358) and group 2—comprised employable patients (n=504).

A total of 208 patients were diagnosed with both cardiovascular disease and DM2.

Elderly patients with DM2 had worse prognosis and increased five-year mortality compared with patients of the same age group without DM2.

Statistically significant differences in long-term outcomes were found in adult patients (p=0.004) only in group with longer duration of diabetes, unlike the group with DM2 onset.

In conclusion, Type 2 DM increased 5-year mortality rate of elderly patients with myocardial infarction.

However, younger patients with both myocardial infarction and DM2 had more complications in the early post-MI period compared with patients of the same age group without DM2 but did not show any statistically significant differences in the long-term outcome.
