In this video Prof Barlis reviews a frequently performed test used to take xray images of the arteries around the heart. These arteries, known as the coronary arteries, deliver blood, oxygen and nurients to the heart muscle itself so it can keep pumping and supplying the entire body with the nutrients it needs. The angiogram allows visualisation of the inside of the arteries and can detect narrowings or blockages that may develop due to cholesterol plaque build up.
