Is bypass surgery absolutely necessary for 90% heart blockage?

"Bypass" generally refers to coronary artery bypass surgery. A 90% blockage in the heart does not necessarily require bypass surgery; stent implantation is also a viable option. The detailed analysis is as follows:

Heart blockage refers to the narrowing or occlusion of the coronary artery lumen caused by atherosclerosis, which may lead to symptoms such as chest pain, chest tightness, palpitations, or others. When there is a 90% blockage in the heart, treatment options such as stent implantation or coronary bypass surgery can be performed to alleviate the vascular obstruction. However, it cannot be definitively determined whether a patient with 90% heart blockage should undergo stent placement or bypass surgery—the choice depends on the individual patient's overall health condition. Therefore, bypass surgery is not always mandatory.

If a 90% heart blockage is detected, it is recommended to seek timely medical attention and follow the doctor's advice for treatment to avoid delaying the condition. In daily life, one should maintain healthy habits, keep a regular sleep schedule, and avoid staying up late. Additionally, maintaining emotional well-being, reducing stress and anxiety, and avoiding extreme emotional fluctuations are important.
