If all of his native coronary arteries and bypass grafts are blocked, then his heart is surviving on small blood vessels called collaterals that may provide enough blood to keep the heart pumping but may not be able to supply enough blood to prevent angina. We may have something to offer your father. You would need to send a copy of your father's operative report from his bypass surgery, recent clinical notes, and his angiogram for our review prior to his appointment. In the meantime, you should speak with his cardiologist about increasing the doses of some of his anti-anginal medications. I hope you find this information useful.
