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.
Good tool. Treadmill stress test is a good test to evaluate for risk stratification for coronary artery disease. It is most helpful in intermediate risk category. It may not be accurate in certain subsets. It has 67% sensitivity and 72% specificity to identify cad. For definitive diagnosis further testing e., g., coronary angiogram or stress test with nuclear imaging may be required.

Is treadmill test good enough to rule out possible coronary artery and heart disease?

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.

Which is the most preferred and accurate test when it comes to diagnosing coronary artery disease for doctors?

Catheterization. There are issues with any, but for planning surgery, cath is still, the best. Exercize or nuclear screening has good use. Ct scans are getting better! but calcium may be present without stenosis and vice versa. Read more...

Is an exercise stress test safe if I have coronary artery disease?

Yes. The risk of of a serious complication during stress testing is 1 in 10, 000. Patients with frequent and ongoing chest discomfort or aortic stenosis may not be candidates for stress testing as their risk is higher. Read more...

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...

Does coronary CT scan w/calcium score rule out coronary artery disease/atherosclerosis?

Coronary CT. Calcium score CT doesn't rule out atherosclerosis or chance of heart attack. With that said the more calcium the more volume of plaque both calcified and noncalcified. The test can help when the need for drug therapy isn't clear. Read more...

What are the tests for coronary artery disease?

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.

Actually Few/None, . Though dominant human behavior, physicians are trained to wait for evidence of advanced disease, largely in this order of ability to detect disease earlier: 1. Calcification in the artery walls, 2. Obstructions visible on coronary angiograms, 3. Evidence of symptoms & heart damage or, typically the latest to detect/recognize, 4. Stress tests. I rec. A better alternative: optimize driving factors. Read more...
