Correlation between Duration of Illness and Treadmill Test in Type II Diabetes Mellitus Patients

Background: Diabetes is a common endocrine disorder that leads to multiple systemic complications. There is a link between diabetes and coronary artery disease for many years. It plays an important role in atherogenesis and causes cardiovascular morbidity and mortality. The duration of diabetes seems to influence the rapidity of atherogenesis. The treadmill test is a relatively inexpensive tool to screen patients with diabetes for coronary artery disease. Aim and Objective: To use treadmill test in patients with type II diabetes mellitus and correlate with sociodemographic data and the duration of diabetes. Materials and methods: This was a cross-sectional observational study that was done among 79 diabetic patients who underwent treadmill test from a tertiary care hospital at Mangalore. The result of the treadmill test, sociodemographic profile, and duration of diabetes were obtained and analysed using SPSS software v20. Results: Among 79 diabetic subjects, 21 (26.3 %) were females and 58 (73.8 %) were males. The mean±SD age was 56.89±10.87 years. The duration of diabetes ranged from newly detected diabetics to 40 years with mean±SD of 7.43±7.28 years. Among the 79 participants, 27 were positive for inducible ischemia after TMT, 26 were negative and 16 showed an inconclusive result. Statistically significant results were observed between the duration of diabetes and a positive treadmill test. Conclusion: The increasing duration of diabetes was associated with a positive treadmill test. Early identification and control of diabetes, use of treadmill tests could prevent mortality from coronary artery disease in patients with diabetes.
