Once they were in there with that tiny camera and could see your arteries, they determined there was not a blockage as suspected, so did not put in a stent. Originally probably you had chest or arm pains, and especially if you’re over middle-age, the assumption is blocked arteries, and to put in a stent. Sometimes they get in and see it’s not needed. Consider yourself lucky, it means you’re in better shape than they thought. Of course, question for your doctor is what was the presenting issue and why did it happen? Sometimes panic attacks or severe stress mimic heart attack symptoms.
And it's one of the guy's carotid arteries....Not his coronary arteries!!
