Hi, Cristy. Do you mean coronary obstruction? Do you have any symptoms?
If your coronary artery stenosis is above 50%, you'd better take antiplatelet and lipid-lowering drugs under the cardiologist's instruction.
If your coronary arterial stenosis is above 75%, your doctor may perform stent surgery or coronary artery bypass surgery.
You need to actively control your blood glucose, blood pressure, and lipid levels, quit smoking and limit alcohol, and a low-salt, low-fat diet.
For your throat lump, it is recommended that you go to the otolaryngology for pathological examination.
Rib bumps may be caused by costochondritis, costal trauma, costal tumor, and rib deformity. You can take a chest CT scan to clarify the diagnosis.
