You or your relative have been prescribed a coronary angiography, and you want to know why it is necessary and why doctors may recommend this procedure. Let's understand which diseases and conditions can be the reasons for performing a coronary angiography:

1. Coronary artery disease (CAD): This is a condition caused by inadequate oxygen and nutrient supply to the heart muscle (myocardium) due to the narrowing of the coronary arteries. Coronary angiography helps doctors visualize the location of vessel narrowing, determine the diameter of the artery lumen, and make decisions about treatment.
2. Angina (unstable angina, angina not responsive to medication, post-infarction angina): If you experience chest pain episodes due to insufficient blood supply to the heart, doctors may prescribe coronary angiography. This allows them to see if there are any artery constrictions causing angina and determine how to improve the heart's blood supply.
3. Myocardial infarction (heart attack): When a heart attack occurs, a portion of the heart muscle may die due to a lack of blood supply. Coronary angiography helps doctors see which arteries are blocked and decide how to restore their patency.
4. Preoperative evaluation for heart surgery: If heart surgery is planned, doctors may suggest coronary angiography to ensure that the arteries do not have significant problems.
5. Unclear symptoms related to the heart: Sometimes patients may experience chest discomfort, rapid heartbeat, or other symptoms associated with the heart, but the exact cause is unknown. In such cases, coronary angiography can help exclude or confirm various heart conditions.

It is important to understand that coronary angiography is a diagnostic procedure that helps doctors visualize the condition of your heart's arteries and make the right decision regarding further treatment. If you have been scheduled for this procedure, do not worry - it is performed by experienced specialists under X-ray guidance and helps preserve your health!
