As a medical professional with expertise in cardiology, I can provide you with information on what can cause an abnormal nuclear stress test.
A nuclear stress test is a non-invasive imaging test that evaluates how well your heart works during physical activity or while you're given medication that increases your heart's activity. An abnormal result can indicate that your heart is not getting enough blood flow, which could be due to coronary artery disease (CAD) or other heart conditions. Here are some factors that can lead to an abnormal nuclear stress test:
1. Coronary Artery Disease (CAD): The most common cause of an abnormal test is the narrowing of the coronary arteries due to plaque buildup, which restricts blood flow to the heart muscle.
2. Prior Heart Attack: Scar tissue from a previous heart attack can affect the test results.
3. Heart Failure: The heart's inability to pump blood effectively can lead to an abnormal test.
4. Valvular Heart Disease: Abnormalities in the heart valves can affect blood flow and result in an abnormal test.
5. Anemia: A lack of red blood cells can reduce the heart's efficiency and cause an abnormal test.
6. High Blood Pressure: Uncontrolled hypertension can stress the heart and lead to an abnormal result.
7.
Electrolyte Imbalances: Abnormal levels of minerals like potassium or calcium can affect heart function.
8.
Physical Deconditioning: A sedentary lifestyle can lead to a heart that is not as efficient as it should be.
9.
Medications: Certain medications can affect heart function and lead to an abnormal test.
10.
Technical Issues: Sometimes, the test itself can have technical problems that affect the results.

1. Interpretation Errors: The results can be misinterpreted due to various reasons, including the experience of the interpreting physician.

2. Other Medical Conditions: Conditions like hypertrophic cardiomyopathy, where the heart muscle is thicker than normal, can also cause an abnormal test.
It's important to note that an abnormal test does not necessarily mean you have a heart condition. It may prompt further testing or evaluation by a healthcare provider to determine the cause of the abnormal result.

An abnormal stress test usually means that you have blockage in heart arteries. A nuclear stress test result should be interpreted in the light of a person's symptoms, his risk for coronary artery disease etc. The nuclear stress test has the ability to quantify the severity of abnormality.
