Is heart bypass surgery dangerous? Will the patient be very painful after the operation?

Classification: medical and health care

Problem description:

My father is 53 years old. He was recently found to have angina pectoris. He had a coronary angiography. Left anterior descending branch stenosis 85%. The doctor said that a bypass operation was needed. Now he hasn't decided whether to do it or not! Yesterday, I watched the video of the operation in anzhen hospital in 2004. I think it's really a big operation, and the wound seems to be very big. It's been two years. Has the technology improved? Is it dangerous? We still have to open the box. Does it take a long time to recover after the operation? Is it difficult? I'm also worried that the joint will scar and narrow again! Many questions, I hope everyone can talk about them!

Analysis:

Heart bypass surgery involves bypassing blocked arteries to improve the blood and oxygen supply to the heart. This operation may affect the memory and mental function of patients, so that about13 patients still show detectable mental dysfunction five years after operation.

In order to reduce the risk, it is necessary to keep the graft section of heart bypass surgery unobstructed and reduce the need for repeated heart bypass surgery.

In patients who have just finished heart bypass surgery, depression can lead to three times the risk of heart disease in the first year of surgery.
