Coronary angiography is a diagnostic procedure that enables visualization of the internal morphology of the coronary arteries and assessment of blood flow velocity. Widely used in clinical practice, it holds significant practical value in diagnosing various cardiac diseases—and is considered the gold standard for diagnosing coronary artery disease (CAD). Beyond aiding in disease diagnosis, coronary angiography also provides precise, evidence-based information essential for guiding subsequent treatment decisions.
