Does a positive exercise treadmill test necessarily indicate coronary artery disease?

 A positive exercise treadmill test does not necessarily indicate coronary artery disease (CAD). This test serves only as a screening tool; an abnormal result suggests possible myocardial ischemia (inadequate blood supply to the heart muscle). Other conditions—including myocarditis, cardiomyopathy, and arrhythmias—may also yield false-positive results. If you experience chest pain, palpitations, or shortness of breath during physical activity, seek prompt medical evaluation and further diagnostic testing.

 The exercise treadmill test increases cardiac oxygen demand through controlled physical exertion and monitors electrocardiographic (ECG) changes to assess myocardial perfusion. In patients with CAD, coronary artery stenosis leads to myocardial ischemia during exercise, typically manifesting as characteristic ECG abnormalities—making this test a key component of CAD screening. For individuals definitively diagnosed with CAD, standard pharmacotherapy and lifestyle modifications effectively control disease progression; in severe cases, interventional procedures (e.g., percutaneous coronary intervention) may be indicated.

 Numerous non-coronary conditions can also produce false-positive treadmill test results, including valvular heart disease, myocardial injury, and electrolyte imbalances—all of which may confound interpretation of test parameters. A positive treadmill test alone is insufficient for definitive diagnosis; clinical correlation with coronary imaging (e.g., coronary CT angiography or invasive angiography) and comprehensive assessment of symptoms are essential to avoid misdiagnosis or inappropriate clinical decisions.

 Maintain a moderate, consistent exercise routine in daily life; avoid excessive fatigue and intense physical exertion. Adhere to a low-fat, low-sodium diet to support coronary health and preserve stable cardiac function.
