Yes: Time to change. Need to exercise, eat right, quit smoking. Control hypertension and cholesterol. Develope treatment plan with your doctor.

Yes and no: This means that you have blockage in your arteries, which is not necessarily severe enough to require surgery. It is also a marker of hardening of the arteries throughout your body. You should quit smoking, control your cholesterol and blood pressure, and sugar (if you are diabetic). You should be evaluated by a vascular surgeon to see whether anything else needs to be done.
