A nuclear stress test evaluates blood flow to the heart muscle at rest and during stress. Stress may be created by walking on a treadmill or by medication if a patient cannot exercise adequately. Imaging helps identify areas of reduced blood supply that may suggest coronary artery disease.
The test can help guide medication decisions, further imaging, or coronary angiography when appropriate.
Symptoms patients may notice
- Chest pain, pressure, tightness, or discomfort with activity
- Shortness of breath or unexplained fatigue
- Abnormal EKG or prior abnormal stress test
- Known coronary artery disease, prior stent, bypass, or heart attack
- Need for risk assessment before certain procedures or activity planning
How we evaluate this condition
- Pre-test review of symptoms, medications, EKG, and ability to exercise
- Stress imaging with careful monitoring of heart rhythm, blood pressure, and symptoms
- Cardiologist interpretation and follow-up recommendations
Treatment and care options
- Medication optimization for coronary disease or symptoms
- Lifestyle and risk-factor management
- Further testing or coronary angiography referral when findings suggest significant ischemia
When to seek urgent care
Do not wait for outpatient testing if you have active severe chest pain, severe shortness of breath, fainting, or symptoms of a heart attack. Call 911.
