The primary method for detecting heart blockage is cardiac catheterization and angiogram.
Cardiac Catheterization and Angiogram Explained
This procedure allows doctors to visualize blockages in the heart arteries. Here's a breakdown:
- Catheter Insertion: A long, thin, flexible tube called a catheter is inserted into a blood vessel, typically in the groin or wrist.
- Guidance to the Heart: The catheter is carefully guided through the blood vessel to the heart.
- Dye Injection: A special dye is injected through the catheter into the heart's arteries.
- X-ray Imaging (Angiogram): X-ray images, called angiograms, are taken to show how the dye flows through the arteries. This reveals any areas where the arteries are narrowed or blocked.
In essence, the dye acts as a contrast agent, making the arteries visible on the X-ray. Blockages appear as areas where the dye flow is restricted or absent.
