Can cornary heart disease be treated with statins and diet alone or is stent or surgery needed?

It all depends on: the extent, severity, and anatomic location of the coronary artery disease.

Depends: Hi. All three means are used, depending on the nature of the lesion(s), the coronary artery/arteries involved, targets for stenting or surgery, etc. Talk with your cardiologist, and if it would make you feel better, get a second opinion. Good luck!

Depends: It depends on the number of arteries affected, the degree of disease, and other associated medical conditions. Stents are needed when critical arteries are blocked. Surgery is generally needed when multiple arteries or severe disease at the start of a major coronary artery is present. Remember though that stents or surgery are just one treatment. Plus, arteries elsewhere are affected too.
