What are the key differences between Angiography and Angioplasty?

Many patients confuse angiography and angioplasty, despite the procedures serving different purposes. Angiography is a diagnostic test used to detect blocked coronary arteries, while angioplasty is a treatment that restores blood flow using balloons and stents. Cardiologists say understanding the distinction can reduce fear, improve treatment decisions, and encourage faster medical attention.
