The Gold Standard for Diagnosing Coronary Heart Disease

Coronary heart disease (CHD) is primarily diagnosed using invasive coronary artery examinations, which are considered the gold standard in accurate assessment. Procedures such as coronary angiography and intravascular ultrasound provide detailed insights into the path, structure, and potential narrowing of the coronary arteries. These diagnostic tools allow physicians to precisely evaluate the nature and severity of any vascular abnormalities.

Understanding Coronary Angiography

Coronary angiography involves the puncture of either the radial artery in the wrist or the femoral artery in the groin. Once access is established, a catheter is carefully guided through the arterial system and positioned at the opening of the coronary arteries. A contrast dye is then injected, and multiple X-ray images are taken from various angles to examine the flow and structure of the blood vessels. This method enables doctors to identify any blockages or irregularities that may indicate coronary heart disease.

Enhancing Diagnostic Accuracy with Intravascular Ultrasound

For a more detailed analysis, intravascular ultrasound (IVUS) can be used alongside traditional angiography. By inserting an ultrasound-equipped wire through the catheter and into the coronary artery, medical professionals can obtain high-resolution images from within the vessel. This technique allows for a comprehensive evaluation of plaque composition, vessel wall characteristics, and overall arterial health, offering a more complete picture of cardiovascular risk.

Choosing the Right Diagnostic Approach

While coronary angiography remains the most widely accepted and commonly used method for diagnosing CHD, advancements in imaging technology continue to refine diagnostic capabilities. Depending on the patient's condition, medical history, and symptoms, healthcare providers may opt for a combination of techniques to ensure the most accurate diagnosis. Ultimately, coronary angiography stands as the benchmark for evaluating coronary artery disease, offering reliable and actionable insights for effective treatment planning.
