Final answer:
The three past surgical histories that indicate a history of CAD are coronary interventions such as angioplasty and stenting, coronary artery bypass grafting (CABG), and endarterectomy.
Step-by-step explanation:
The three past surgical histories that indicate a history of CAD (Coronary Artery Disease) are:
- Coronary interventions such as angioplasty and coronary stent: This surgery is performed to open up blocked or narrowed arteries in the heart by using a balloon-like tip to widen the opening and inserting a stent to prevent subsequent collapse of the vessel.
- Coronary artery bypass grafting (CABG): In this procedure, a non-vital superficial vessel from another part of the body or a synthetic vessel is inserted to create a bypass around the blocked area of a coronary artery.
- Endarterectomy: This surgical removal of plaque from the walls of a vessel is typically performed on the carotid arteries of the neck.
