Percutaneous coronary intervention

**Percutaneous Coronary Intervention: A Comprehensive Guide**

Percutaneous coronary intervention (PCI), also known as coronary angioplasty, is a minimally invasive procedure used to treat narrowed or blocked arteries in the heart. It involves inserting a catheter, a thin tube with a balloon on its tip, into the narrowed artery. The balloon is then inflated to widen the artery and restore blood flow. PCI may also involve the placement of a stent, a small metal coil, to keep the artery open.

PCI is typically performed on patients with stable angina (chest pain caused by narrowing of the coronary arteries) or unstable angina (chest pain that is new or worsening). It can also be performed in patients with a heart attack to open up a blocked artery and restore blood flow to the heart muscle.

PCI is a relatively safe and effective procedure. The risks include bleeding, bruising, and infection at the insertion site. In rare cases, PCI can cause serious complications such as heart attack, stroke, or kidney failure.

The benefits of PCI include relief of angina, improved exercise tolerance, and reduced risk of heart attack. PCI can also help to prevent the need for coronary artery bypass surgery (CABG).

If you are experiencing chest pain, talk to your doctor about whether PCI is right for you.
