How do doctors treat a blocked blood vessel?• Diagnosis – Use an angiogram to
detect a blocked blood vessel– A radioactive dye is injected into
the blood and X-rays are used to view the passage of the blood through the blood vessels
• Treatments– Angioplasty – A balloon is
inserted via a catheter and is blown up to expand the artery to push the plague against the walls and restore blood flow
