which of the following is true of an angioplasty?
it is a recording of the electrical activity of the heart used to measure risk for heart attack.
it is a stress test during which workload is increased gradually until an individual reaches maximal fatigue.
it is the deposition of fat in the walls of arteries, leading to the formation of plaque.
it is a procedure in which a balloon - tipped catheter is inserted and inflated to widen the inner lumen of an artery.
it is the death of an area of heart muscle caused by reduced blood flow due to coronary artery obstruction.

Explanation:

Angioplasty is a medical procedure. A balloon - tipped catheter is inserted into a narrowed or blocked artery. When inflated, it widens the inner lumen (the hollow part) of the artery, improving blood flow.

• The first option describes an electrocardiogram (ECG), not angioplasty.
• The second option is a description of a stress test.
• The third option is about atherosclerosis (plaque formation).
• The fifth option is about a myocardial infarction (heart attack).

Answer:

It is a procedure in which a balloon - tipped catheter is inserted and inflated to widen the inner lumen of an artery.
