Heart Blockage identification techniques.

Dear Ask The Doctor: What are the techniques other than Angiography to accurately identify Heart blockages r coronary artery blockages?

Dear Vineet: Tests used to identify coronary artery blockages may include:

- Stress tests - non invasive techniques that identify the reduced capacity of heart muscles

- Coronary angiogram or CT angiogram - an invasive procedure, which is the preferred method in identifying blockages, because the anatomy of the coronary vessels can be assessed directly to identify the degree and location of the blockage.
