How Does the Presence of Diabetes Affect the Course of Acute Coronary Syndrome in Elderly Patients in Actual Clinical Practice?

The number of elderly patients with diabetes mellitus (DM) is constantly growing in general population. Accordantly, we have the growth of such patients in the group of acute coronary syndrome (ACS). Aim. To compare clinical characteristics of the elderly patient (>75 years old) with and without DM. Material and methods . This retrospective study included 1133 ACS patients who were aged ≥75 years and admitted to the City Clinical Hospital №1 from 01.01.2015 to 31.12.2016. Median age was 80 years, 66% were women. We analyzed 4 patient subgroups: Group 1 – 105 patients with ST-segment elevation myocardial infarction (STEMI) and DM, Group 2 – 254 STEMI patients without DM, Group 3 – 222 non-STEMI patients with DM and Group 4 – 552 non-STEMI patients without DM. We used Student’s t-test and c2 tests to find significant difference between pairs of groups. Results . Median age of patients in 4 groups was 80, 81, 81 and 80 years (p>0.05), age variance was 75-100 years. DM was found in 29% of all elderly patients with no difference between STEMI and non-STEMI groups. STEMI and non-STEMI patients with DM were more likely women. NonSTEMI patients with DM more often had hypertension, previous stroke, lower median Hb (121 vs 127 g/l; p
