I'm really worried about my dad's recent angiography test results. It showed he has a 100% blockage in two arteries and 95% in a third artery, with just one vein working properly. I'm trying to understand if he should consider bypass surgery or angioplasty. Which option is generally more effective for extending lifespan?

For blockages of 100% in two arteries and 95% in the third artery, bypass surgery would be more effective in this case. Bypass surgery involves creating new pathways for blood to flow to the heart muscle, bypassing the blocked arteries. This can help improve blood flow to the heart and relieve symptoms such as chest pain. It is also known to extend lifespan and reduce the risk of future heart attacks compared to angioplasty. The patient should consult with a cardiac surgeon to discuss the best treatment option and further details regarding the bypass surgery procedure and post-operative care.
