Can a treadmill test, 2D echo, or ECG detect an 80% heart blockage, or is an angiogram the only way to find this out? I'm really curious because I want to understand what these tests can actually show.

0% heart blockage cannot be directly traced by a treadmill test, 2D echo, or ECG. These tests can provide important information about the heart's function and structure, but they may not definitively show the extent of blockages in the coronary arteries. The gold standard for diagnosing blockages in the arteries is a coronary angiogram (angio). It is an invasive procedure where a dye is injected into the arteries to visualize any blockages. If you suspect significant blockages in your coronary arteries, it is best to consult with a cardiologist for further evaluation and management.

-
Treadmill Test (Exercise Stress Test)
- Detection Capability: Can suggest reduced blood flow but not precisely quantify blockage.
-
2D Echocardiogram (2D Echo)
- Detection Capability: Limited in directly identifying coronary artery blockages.
-
Electrocardiogram (ECG)
- Detection Capability: Detects heart rhythm issues or signs of past heart damage, not exact blockage severity.
-
Coronary Angiogram
- Detection Capability: Precisely identifies and measures artery blockage, including an 80% blockage.
-
Summary and Recommendations
- Guidance: Angiogram is necessary if symptoms and non-invasive test results suggest significant blockage.
- Consultation: Cardiology consultation recommended for diagnosis and management.
-
Additional Notes
- Risks and Benefits: Angiogram is invasive but provides accurate blockage assessment.
- Alternative Tests: CT coronary angiography may be considered if applicable.

View allI'm just a bit confused after seeing my Echo results. It shows I have normal pulmonary arteries, but the summary mentions mild PHT. Is that really possible to have mild PHT even if the pulmonary arteries look normal? Just trying to understand what this might mean for my health.
yes it is possible, there might be slight increase in pressure due to various other reasons

What are the best foods to eat to lower triglycerides?
Omega-3 rich fish include salmon, sardines, mackerel, herring, tuna, and halibut. Other foods that help lower triglycerides include fiber-rich foods such as oats, flax meal, and beans. Olive oil, especially when substituted for animal fats like butter or lard, is another food that can help lower triglycerides.
