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.
