Exercise Treadmill Stress Test in Baytown

An exercise treadmill stress test evaluates how well your heart responds to increased physical demand.

At Houston Cardiovascular Institute, Dr. Shehzad Sami performs this non-invasive procedure to assess blood flow, identify arrhythmias, and detect signs of coronary artery disease in patients from Baytown, Mont Belvieu, and Dayton, TX.

What Is an Exercise Treadmill Stress Test?

An exercise treadmill stress test—also called a cardiac stress test—monitors cardiovascular performance during controlled physical exertion. Patients walk on a motorized treadmill while connected to an electrocardiogram (ECG). The test measures heart rate, blood pressure, electrical activity, and symptoms under increasing workload. This allows clinicians to detect abnormal cardiac responses that may not appear at rest.

Benefits of a Treadmill Stress Test

A treadmill stress test provides clinically relevant information for diagnosis and management of cardiovascular disease. It is frequently used as a first-line test in patients with suspected ischemic heart disease.

Clinical benefits include:

Identifying exercise-induced myocardial ischemia
Correlating chest pain with ECG changes or exertional symptoms
Estimating functional capacity and exercise tolerance
Assessing the efficacy of previous interventions (e.g., stents, bypass)
Guiding treatment decisions in patients with stable angina or multiple risk factors

This test is non-invasive, requires no sedation, and is completed in a short outpatient visit.

Who Should Get an Exercise Treadmill Stress Test?

A treadmill stress test is appropriate for patients with symptoms, risk factors, or known cardiac disease.

Indications may include:

Exertional chest discomfort or dyspnea
Unexplained fatigue or dizziness during physical activity
Evaluation before surgery or initiating an exercise program
Risk stratification in patients with hypertension, diabetes, or hyperlipidemia
Surveillance in individuals with a history of coronary artery disease

Before recommending the test, Dr. Sami performs a clinical assessment to determine appropriateness based on current guidelines.

How the Treadmill Stress Test Is Performed

The procedure begins with placing ECG electrodes on the chest. A baseline ECG and blood pressure reading are taken at rest. The patient then walks on a treadmill using a graded protocol (commonly the Bruce or modified Bruce protocol) that increases the speed and incline every few minutes.

Key procedural elements:

Continuous ECG monitoring throughout the test
Blood pressure readings at regular intervals
Patient observation for symptoms such as angina, palpitations, or leg fatigue
Test termination upon reaching target heart rate, onset of significant symptoms, or diagnostic findings

After exercise, patients are monitored during recovery until vital signs normalize.

Recovery and Interpretation of Results

Most patients experience no significant post-test symptoms and may resume normal activities immediately. Results are typically interpreted on the same day.

Key outcome measures include:

Presence of ST-segment changes
Development of arrhythmias
Achievement of target heart rate
Hemodynamic response under load
Symptom correlation

If results are abnormal or inconclusive, Dr. Sami may recommend additional tests such as myocardial perfusion imaging, echocardiography, or coronary angiography.

Cost and Insurance Coverage

The cost of an exercise treadmill stress test depends on insurance benefits and clinical indication. Medicare and most commercial insurance providers offer coverage when the test is medically necessary.
