Please pay attention to my words, it is vascular recanalization, usually interventional surgery to implant stents, or surgical bypass (coronary artery bypass grafting).
Specifically, if you have multiple vascular lesions, or a single vessel, but it is relatively long, or unprotected left main artery lesions, then it is an indication of surgical bypass; On the contrary, if it is simple and the lesion is not diffuse, then interventional surgery is the first choice.
Of course, sometimes we don't just consider the degree of stenosis, because sometimes the degree of stenosis is not that serious, but it may be that unstable plaques may rupture at any time, which will lead to severe stenosis or even occlusion of blood vessels at once, so we also consider recanalization treatment.
