Background:Diabetes mellitus is one of the leading causes of vascular disease. The caseload is expected to reach 350 million by the year 2030, and it is estimated that up to 30% of patients are undiagnosed.
Objective: The aim of the study was to explore the prevalence of prediabetes in patients admitted with acute coronary syndromes (ACS) who were not known to have diabetes and to determine the impact of prediabetes on in-hospital clinical outcomes versus non-diabetic patients.
Patients and methods: This prospective study was conducted on 60 patients with acute coronary syndrome who were admitted to the intensive care unit (ICU), Internal Medicine Department, Faculty of Medicine, Zagazig University during the period from September 2019 to March 2020. All studied subjects were subjected to full history taking complete clinical examination, complete blood count, glycosylated haemoglobin (HbA1c), lipid profile, serum creatinine and oral glucose tolerance test (OGTT), ECG and ECHO.
Results: There was a statistical significant difference between the studied groups regardingacute coronary syndrome types, glycated haemoglobin (HbA1c), serum creatinine, and high-density lipoproteins cholesterol. There was statistically significant difference between the studied patients grouped according to the clinical outcome regardingACS types.
Conclusion: Prediabetes is common in patients presenting with acute coronary syndrome who are not previously known to have diabetes. Pre-diabetic patients had worse in-hospital clinical outcomes compared with patients without diabetes. Pre-diabetic patients with ACS have greater prevalence of cardio-metabolic risk factors (abdominal obesity, and hypertension) as compared to non-diabetic patients.
