The blockage prevents the heart from getting oxygen and important nutrients. Abnormal results in tests such as diagnosing chest pain, cardiac arrest, electrocardiogram (EKG) or exercise stress testing can lead to the appearance of coronary heart disease and coronary microvascular disease. So detecting blockages is important because over time, blockages can cause chest pain, especially with physical activity or stress, or a heart attack. If you have a heart attack, a heart scan can help your doctor plan your treatment. So what does cardiac angiography mean? Simply put, it is a test. Coronary angiography is a procedure that uses special dye (contrast material) and x-rays to see how blood flows through the heart's arteries. In this case, any one enforcement has been expanded. Coronary angiography is often done with cardiac catheterization, a procedure that measures the pressures in the heart chambers. Contrast agent is injected into certain parts of the heart and large blood vessels through a cardiac catheter to make the heart and blood vessels visible, and rapid films are taken to show pathological changes in the anatomical structure of the heart and large blood vessels as well as circulatory function. Before the test begins, you will be given a mild sedative to help you relax. An area of the body (an arm or groin) is cleaned and numbed with a local anesthetic (anesthetic). The cardiologist threads a thin, hollow tube called a catheter through the artery and carefully moves it up into the heart. The x-ray images help the doctor position the catheter. Once the catheter is in place, a dye (contrast material) is injected into the catheter. X-ray images are taken to see how the dye travels through the arteries. This dye helps highlight any blockages in blood flow. This process usually lasts 30 to 60 minutes. How to prepare for the test In any case, the scope of "certification" has been expanded. You should not eat or drink anything 8 hours before the test. You may need to stay in the hospital the night before your test. Otherwise, you will report to the hospital on the morning of the test day. You will wear a hospital gown. You must sign a consent form before taking the test. Your healthcare provider will explain the procedure and its risks. If you: Are allergic to any medications, or if you have had a bad reaction to contrast dye in the past Currently taking Viagra Possibly pregnant What the test felt like Either case has been expanded. In most cases, you will wake up during the test. You may feel some pressure where the catheter is placed. You may feel flushing or warmth after the dye is injected. After the test, the catheter is removed. You may feel a lot of pressure applied to the insertion site to prevent bleeding. If a catheter is placed in the groin, you will be asked to lie flat for several hours to several hours after the test to avoid bleeding. This may cause mild back discomfort. if: The first time you have angina. Your angina gets worse, doesn't go away, happens often, or happens while you're at rest (called unstable angina). You have aortic stenosis. You have atypical chest pain when the rest of the examination is normal. Your cardiac stress test was abnormal. You are going to have heart surgery and you are at high risk for coronary artery disease. You have heart failure. You are diagnosed with heart disease. |
