Final answer:
Treatment options for a single blocked artery include lifestyle changes, medications, angioplasty, endarterectomy, or coronary bypass surgery.
Step-by-step explanation:
When only one artery is blocked, the typical treatment options include lifestyle changes, medications, angioplasty, endarterectomy, or coronary bypass surgery. Lifestyle changes may involve weight loss, smoking cessation, regular exercise, and a diet low in sodium and saturated fats. Medications may be prescribed to reduce cholesterol and blood pressure. Angioplasty is a procedure in which a catheter with a balloon tip is inserted into the narrowed artery and inflated to widen the opening. A stent may also be inserted to support the vessel and prevent collapse. Endarterectomy involves surgically removing plaque from the vessel walls, commonly performed on the carotid arteries. In coronary bypass surgery, a new vessel from another part of the body or a synthetic vessel is used to create a path around the blocked area of a coronary artery.
