Abstract:

Background and aim: Diabetic patients are at an increased risk for the development of macrovascular complications such as acute myocardial infarction (AMI), stroke and lower-limb amputations (LLA). This study aimed to explore a. the incidence of hospital admission for macrovascular complications (AMI, stroke, and LLA); b. to assess the impact of hospital admission on survival in a large population with diabetes mellitus living in Kazakhstan.

Materials and methods: Retrospective observational study using a nationwide anonymized electronic database of 98.469 hospitalized diabetic patients from Kazakhstan between November 2013 and December 2019. The incidence of hospital admissions for AMI, stroke and LLA were obtained to calculate their all-time cumulative incidence, and survival rate at follow-up.

Results: The all-time cumulative incidence of hospital admissions was 1.30% for AMI, 1.94% for stroke and 2.94% for LLA. The incidence of macrovascular complications was statistically significantly higher in males compared to females (p-value<0.05). 29.03% of diabetic patients with AMI, 25.16% with stroke and 29.80% with LLA died during the follow-up period. Individuals with AMI had 3.58 (95% CI 3.20; 4.01) times, with stroke 3.86 (95% CI 3.52; 4.24) times and with LLA 3.63 (95% CI 3.38; 3.88) times higher hazard of 6-year death compared to diabetic patients free of these complications. The stratified survival analysis by sex indicated the lower survival in women than in men, and the lower survival in older age groups.

Conclusion: The results from this study shows that cumulative incidence of AMI and stroke among diabetic patients admitted in the hospitals in Kazakhstan between 2013-2019 years was similar to the estimates from other countries, but the incidence of LLA was significantly higher in Kazakhstan. Patients with diabetes mellitus (DM) in Kazakhstan are at high risk of excess mortality if they suffer from macro-vascular complications. More research is required to explore the reasons for the high incidence of those complications, in order to propose systematic solutions for lowering the incidence and improve survival.
