Angioplasty is a minimally invasive medical procedure used to unblock blood vessels, most commonly the coronary arteries. During balloon angioplasty, a balloon-tipped catheter is used to compress plaque and widen the artery. Stent angioplasty involves placing a small metal mesh tube called a stent to maintain artery patency. Angioplasty is used to treat conditions like coronary artery disease and angina. Patients typically stay in the hospital for 1-2 days after angioplasty and can return to normal activities after a week of limited physical exertion and gradual exercise. While angioplasty has benefits over alternatives like bypass surgery, risks include pain, bleeding, and artery rupture.
