Question

Which treatment for a heart attack requires threading of a narrow tube or catheter through an artery to the heart? ​?

Answer 1

The answer would be: balloon angioplasty

Defibrillation is a treatment for arrhythmia, not for heart attack. Beta-blocker is a drug that can be given by oral or intravenous. Angina pectoris is pain that caused by heart attack. A coronary bypass will need a surgeon to open up the rib cage, catheterization will not enough. 

Answer 2

The correct answer is angioplasty.

Angioplasty is one of the treatments after heart attack including special tubing with an attached deflated balloon. The tube is threaded up to the coronary arteries. Angioplasty is usually combined with the placement of a small tube called a stent which helps to restore the flow of blood through the artery and decreases its chance of narrowing again.
