koronárangiográfia

Koronárangiográfia, often abbreviated as KAR, is a medical imaging technique used to visualize the coronary arteries, which supply blood to the heart muscle. This procedure is commonly performed to assess the presence and severity of coronary artery disease (CAD), detect heart attacks, and plan treatments such as angioplasty or coronary artery bypass grafting (CABG).

The test involves injecting a contrast dye into the coronary arteries through a catheter, which is guided through the blood vessels to the heart. X-ray images are then taken as the dye moves through the arteries, providing detailed images of the heart's blood supply. The procedure is typically performed in a cardiac catheterization laboratory under sedation or local anesthesia.

Koronárangiográfia is a crucial tool in cardiovascular medicine, aiding in the diagnosis and management of CAD. It helps identify blockages, aneurysms, and other abnormalities in the coronary arteries, enabling healthcare providers to develop personalized treatment plans. The procedure is generally safe, but like any invasive medical intervention, it carries risks such as allergic reactions to the contrast dye, damage to blood vessels, and complications from the anesthesia.

Preparation for a koronárangiográfia may include fasting, avoiding certain medications, and informing the healthcare team about any allergies or medical conditions. The results of the test are interpreted by a cardiologist, who will discuss the findings and recommended course of action with the patient. Follow-up tests or procedures may be scheduled based on the initial results and the patient's overall health status.
