Coronary angioplasty and stent placement is also known as Percutaneous Coronary Intervention (PCI). If you are experiencing symptoms related to Coronary Artery Disease (CAD), e.g., chest pain/tightness/pressure, shortness of breath, sweating at rest, nausea, etc., your cardiologist may suggest a coronary angiogram to look at the heart’s blood vessels. If a blood vessel is narrowed or blocked, coronary angioplasty and stent placement will help to restore blood flow and improve symptoms.
