Description
A cardiac stress test evaluates heart function during physical activity to diagnose coronary artery disease or assess exercise tolerance, with reference costs of ¥500–¥1,000 in China; ChinaMedicalHub assists with hospital booking and interpreter support.
Main Uses
The primary purposes and applicable scenarios for a cardiac stress test are: 1. To diagnose coronary artery disease, 2. To assess the effectiveness of treatment for heart conditions, 3. To evaluate the risk of future heart-related events, 4. To determine safe levels of exercise for patients with known heart disease, 5. To identify the cause of unexplained chest pain or shortness of breath
Normal Range
The normal range for a cardiac stress test typically involves monitoring heart rate, blood pressure, and ECG changes. A normal response includes: Heart Rate (HR) reaching 85-90% of the predicted maximum (220 minus age), Blood Pressure (BP) increasing but not exceeding 250/115 mmHg, and no significant ST-segment depression or arrhythmias on the ECG.
Low Values - Possible Causes
Possible causes of low values or poor performance in a cardiac stress test include: 1. Poor physical conditioning, 2. Medications that lower heart rate or blood pressure, such as beta-blockers, 3. Deconditioning due to prolonged inactivity, 4. Peripheral vascular disease, 5. Neuromuscular disorders affecting exercise capacity
High Values - Possible Causes
Possible causes of high values or abnormal responses in a cardiac stress test include: 1. Coronary artery disease, 2. Hypertension, 3. Arrhythmias, 4. Valvular heart disease, 5. Cardiomyopathy
