A study of ECG abnormalities and treadmill test findings in patients with type 2 diabetes mellitus

Abstract

Background: Guidelines by the American Diabetes Association (ADA), and European Society of Cardiology and European Association for the Study of Diabetes recommend routine use of ECG in patients with type 2 diabetes mellitus (T2DM) having hypertension or any other cardiovascular disease (CVD). Limited evidence is available on the prevalence of ECG abnormalities in T2DM patients. Aims and objective: To study the ECG abnormalities and treadmill test findings in patients with type 2 diabetes mellitus.Materials and methods: Hundred subjects were studied in the Department of Medicine Gandhi Medical College, & Hamidia Hospital, Bhopal from August 2018 to July 2019 after dividing them into diabetes (n=50) and non-diabetes group (n=50). All the subjects underwent fasting and postprandial blood sugar, glycosylated haemoglobin (HbA1c), lipid profile (fasting and post prandial), Electrocardiography (ECG) and treadmill test (TMT) monitoring.Results: Age and sex distribution was similar in both the groups.ST depression & T wave inversion (24%), LAE (20%), LVH (8%), RBBB (4%) and LBBB (4%) were the common ECG findings in diabetes group. Majority of patients with abnormal post prandial lipid profile had positive TMT in diabetes group.Conclusion: Patients with diabetes had more ECG abnormality and majority were TMT positive.
