Is A Treadmill Test Accurate Enough To Rule Out Possible Coronary Artery Disease
No: Stress tests, like a treadmill, only check for coronary artery disease (CAD) that is significant enough to cause low blood flow into a part of the heart, which will show ECG changes or show decreased movement on an echocardiogram. But milder CAD will not be ruled out by treadmill test. ...Read moreSee 1 more doctor answer
Coronary artery disease is the leading cause of death and disability in adults in the U.S. It develops when lipid (fatty) plaques builds up in the arteries. Eventually, the plaque can occlude the artery, thereby stopping blood flow to the organ supplied by that artery. If the artery supplies the heart, blockage causes a heart attack. If the blockage is in a brain vessel, the ...Read more
No: Many times in medicine a single test cannot be counted on to rule out disease completely. Even though stress testing is a very good test to evaluate the blood flow to the heart, it is only one piece of the diagnostic puzzle and sometimes a cardiac catheterization is needed to better decide if there is a problem. ...Read moreSee 1 more doctor answer

Can only using stress test clarify existence of coronary artery disease (blokage due to high LDL, low HDL)?
Stress test is good.: Stress test is designed to detect coronary artery disease. It is not a perfect test, but very good. If you have a normal test you are very unlikely to have any significant fixed blockage of any coronary artery. Blockage is not due to high LDL or low HDL - there are associations, but causality is another story. ...Read more
45y, f having rapid heartbeat and high BP sometimes, diagnosis unstable angina II b, in angiography test having mild coronary artery disease. Need advise?
Several test.: There are several tests for coronary artery disease. A thorough history and physical exam, ekg, ct scan, nuclear studies are all helpful but the best test is a cardiac catheterization. The cardiologist will place a small catheter through a groin vessel up to the heart and inject a special dye into the coronary arteries. The pictures will show if there are any blockages or not. ...Read moreSee 1 more doctor answer
Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more
