A positive stress test result means that your heart isn't getting enough blood flow during exercise. This could be a sign of underlying heart problems, such as:
- Coronary Artery Disease (CAD): This is the most common cause of a positive stress test. It occurs when plaque builds up inside the arteries that supply blood to the heart, narrowing them and reducing blood flow.
- Heart Valve Problems: A faulty heart valve can make it harder for the heart to pump blood efficiently.
- Heart Muscle Problems: Conditions like cardiomyopathy can weaken the heart muscle and affect its ability to pump blood effectively.
What Happens Next?
If your stress test is positive, your doctor will likely recommend further testing to determine the cause of the abnormality. This may include:
- Echocardiogram: This uses sound waves to create images of the heart.
- Cardiac Catheterization: This procedure involves inserting a thin tube into an artery in the arm or leg and threading it to the heart to visualize the coronary arteries and measure blood flow.
- Other tests: Depending on the suspected cause, your doctor may also recommend other tests like an electrocardiogram (ECG) or a Holter monitor.
Important Note: A positive stress test doesn't necessarily mean you have a serious heart condition. It simply means that further evaluation is needed.
Don't Panic: Talk to your doctor about your concerns and discuss the next steps in your care. They will help you understand the results and develop a treatment plan if needed.
