“Can you live with a 100 percent blocked artery?”

You can live with a total occlusion depending on which artery is blocked. Usually when an artery occluded collateral circulation takes over. These are small vessels that take over the blood flow that was lost. However these arteries are much smaller than the occluded vessel and not as much blood is delivered to the heart muscle. If the occluded vessel was large symptoms of lack of oxygen will occur. If the vessel was small there may be few if any symptoms. Any vessel can cause heart muscle damage so even if you don’t die from the blockage the heart will not be normal. That is why blocked arteries should be fixed as soon as possible

Yes. If you have symptoms, sometimes opening it is helpful. I’d need to the angiogram to really say anything specific, however.

Thanks,
