Though rare, serious complications can occur after a coronary angiogram. Some patients may experience severe chest pain, allergic reactions to the contrast dye (such as rash, swelling, or itching), or signs of infection at the catheter insertion site, such as redness or warmth. In rare cases, kidney issues can arise due to the contrast dye, causing symptoms like swelling in the legs or reduced urine output. If any of these serious symptoms occur, it is important to seek medical help immediately. Persistent or severe bleeding, heart attack-like symptoms, or extreme dizziness should be addressed promptly.

Coronary Angiogram
A coronary angiogram is a diagnostic procedure used to visualize the blood vessels of the heart, specifically the coronary arteries, to identify blockages or narrowing caused by conditions like coronary artery disease (CAD). It involves the injection of a contrast dye into the coronary arteries, followed by X-ray imaging to detect any abnormalities. This procedure helps doctors assess the condition of the arteries, determine the extent of the disease, and plan appropriate treatments such as angioplasty, stent placement, or coronary artery bypass surgery (CABG).
Symptoms and Sensations During the Procedure
While the coronary angiogram itself doesn’t have symptoms, patients often experience certain sensations during the procedure. The most common feeling is a warm sensation or flushing as the contrast dye is injected into the arteries. This warmth may spread through the chest or body but typically lasts only a few moments. Patients may also feel mild discomfort or pressure at the catheter insertion site (either in the groin or wrist), which is expected as the catheter is guided to the coronary arteries. Some may also experience heart palpitations or a brief, irregular heartbeat during the dye injection, although this is temporary and usually resolves quickly
Post-Procedure and Recovery
After the procedure, it’s common to experience mild symptoms like bruising or swelling at the catheter insertion site, particularly in the groin area. The insertion site might also feel sore or tender, but these discomforts typically subside within a few days. In some cases, nausea, dizziness, or a sense of lightheadedness may occur as a result of the contrast dye or the procedure’s stress. Bleeding or the formation of a hematoma (blood collection under the skin) at the insertion site can happen but is rare. Patients are monitored after the procedure to ensure that any mild symptoms resolve and that there are no complications.
