Coronary Angiography: Current Clinical Application Status and Future Prospects

Abstract

Coronary angiography is a key technique in the diagnosis and treatment of coronary heart disease in modern cardiology. This review comprehensively discusses the principle, operation process, clinical application and important position of this technology in the diagnosis and treatment of cardiovascular diseases. As the "gold standard" for the diagnosis of coronary heart disease, coronary angiography can visually display the anatomical structure and lesions of coronary arteries, providing an important basis for treatment decision. However, its limitations such as invasive characteristics, high cost and limited ability to diagnose early lesions should not be ignored. In recent years, the development of emerging technologies such as intra-coronary ultrasound imaging (IVUS) and optical interference tomography (OCT) has provided new ways to overcome these limitations. The indications, contraindications, preoperative preparation and other clinical practice issues of coronary angiography are also discussed in this paper, aiming to provide a comprehensive understanding for medical professionals and look forward to the future development direction of this technology.
