Treadmill Test for Asymptomatic Type-2 Diabetes Mellitus to Detect Silent Myocardial Ischemia (Code-T0099)

Introduction: Type-2 diabetes mellitus (T2DM) is associated with an increased risk of cardiovascular diseases, including silent myocardial ischemia (SMI), which often goes undetected due to the absence of symptoms. Early detection of SMI in asymptomatic diabetic patients is crucial for preventing adverse cardiovascular events. The treadmill exercise test is a commonly used tool to assess myocardial ischemia. This study aims to evaluate the effectiveness of the treadmill test in detecting silent myocardial ischemia in patients with asymptomatic type-2 diabetes mellitus.

To investigate the occurrence of silent myocardial ischemia in asymptomatic patients with type 2 diabetes mellitus.

Objectives:

1. To assess the clinical predictors of silent myocardial ischemia in asymptomatic patients with type 2 diabetes mellitus.
2. To evaluate the prevalence of silent myocardial ischemia in asymptomatic type 2 diabetes mellitus patients using a treadmill test.

Methods: This observational study included asymptomatic patients with type-2 diabetes mellitus who underwent a treadmill exercise test (TET) to evaluate cardiac function. The presence of silent myocardial ischemia was determined based on changes in the electrocardiogram (ECG) during the test, along with clinical and demographic data such as age, duration of diabetes, and comorbidities. Patients with abnormal test results underwent further diagnostic evaluations, including coronary angiography.

Results: A significant proportion of asymptomatic patients with type-2 diabetes showed abnormal treadmill test results, indicating silent myocardial ischemia. These patients were found to have higher rates of coronary artery disease when further assessed by coronary angiography. The treadmill test proved to be a reliable tool for detecting SMI in this high-risk population.

Conclusion: The treadmill exercise test is an effective method for detecting silent myocardial ischemia in asymptomatic patients with type-2 diabetes mellitus. Early detection of SMI can lead to better management and prevention of cardiovascular complications.
