Acute coronary syndrome in elderly and senile diabetic patients

Abstract

Acute coronary syndrome (ACS) remains a common cause of hospitalization in diabetes mellitus (DM) patients. It is believed that diabetic neuropathy patients have a high atypical course incidence of acute coronary syndrome, because of the frequent neuropathy development in diabetes patients, but the data on this are quite contradictory. Aim: The study aimed to determine the features of the pain syndrome and its severity in ACS and concomitant diabetes patients. Materials and Methods: The study involved 36 diabetes patients (22 men and 14 women) aged 62-86 years, hospitalized urgently for ACS. Pain syndrome was assessed during hospitalization and immediately after coronary artery revascularization using the following criteria: visual analogue scale (VAS), Numerical Rating Scale (NRS), clinical data, and biochemical markers. Results: Most of the patients (91.67%) complained of chest pain at the time of hospitalization, the rest were not bothered by any pain. Patients described pain as “burning” (30.56 %), “squeezing” (30.56 %), “tightness” (25.0 %), and “tingling” (5.56 %). There were also complaints of difficulty breathing (13.89 %), shortness of breath (11.1 %), and palpitations (41.67 %). The appearance of excessive sweating was noticed by 16.67% of patients. There was no statistically significant difference between the results of VAS and NRS pain scores (p > 0.1). The mean blood glucose level at hospitalization was 8.19±3.45 mmol/l (in men – 8.17±3.61 mmol/l, in women – 8.28±3.13 mmol/L). Glycemia level higher than 10.0 mmol/l was detected in 8 patients, which accounted for 22.22% of all patients. Severe pain syndrome patients dominated in this category (62.5 %). Conclusions: In patients with myocardial infarction and diabetes, the typical clinical picture of ACS prevailed (91.67% of patients) over the painless form. Before revascularization, moderate to severe pain occurred with equal frequency; there were no statistical differences between blood pressure, heart rate, and blood glucose level (p> 0.1) in patients with severe and moderate pain. Hyperglycemia (≥10.0 mmol/l) was detected in 22.22% of patients, among whom severe pain syndrome patients prevailed. _________________________________________________________________________________________ Keywords: elderly patients; diabetes mellitus; acute coronary syndrome; pain syndrome
