koronaarangiograafia

Koronaarangiograafia is a medical imaging procedure used to visualize the coronary arteries, the blood vessels that supply the heart muscle with oxygenated blood. This diagnostic test helps identify blockages, narrowing, or other abnormalities within these crucial arteries. The procedure involves inserting a thin, flexible tube called a catheter, usually through an artery in the groin or arm. This catheter is then guided under X-ray imaging to the opening of the coronary arteries. Once in place, a contrast dye, which is visible on X-rays, is injected into the coronary arteries. The dye highlights the arteries, allowing physicians to observe blood flow and detect any areas of obstruction. Koronaarangiograafia is often performed when a patient experiences symptoms of coronary artery disease, such as chest pain (angina), shortness of breath, or a heart attack. It is also used to assess the effectiveness of previous treatments or to plan for further interventions like angioplasty or bypass surgery. While generally safe, the procedure carries some risks, including bleeding at the catheter insertion site, allergic reactions to the contrast dye, and, in rare cases, damage to the blood vessels or heart. The results of the koronaarangiograafia provide valuable information for diagnosing and managing heart conditions.
