Introduction
Cardiac CTA usually refers to coronary CT angiography. A normal result on coronary CT angiography generally cannot rule out coronary heart disease. Coronary CT angiography primarily uses scanning to evaluate the anatomical structure of the coronary arteries, including the lumen and vessel wall, providing information about whether there is any coronary artery stenosis or occlusion.
Cardiac CTA usually refers to coronary artery CTA examination. A normal result from a coronary artery CTA scan generally cannot rule out coronary heart disease.
Coronary artery CTA primarily evaluates the anatomical structure of the coronary arteries, including details about the lumen and vessel walls, by means of scanning. It helps detect whether there is coronary artery stenosis or occlusion, and can also identify the presence of coronary artery calcification. However, to definitively exclude coronary heart disease, coronary artery CTA alone is insufficient and should be supplemented with coronary angiography for accurate assessment.
When undergoing coronary artery CTA, it is important to choose a reputable medical institution where more precise equipment is typically used, reducing potential errors and improving the accuracy of diagnosing abnormalities in the heart, blood vessels, and heart rate. In daily life, maintaining a cheerful mood and avoiding stress or anxiety is recommended. Diet should be varied, with an emphasis on vitamin-rich fruits.
