Description
Coronary CTA is a non-invasive CT scan to detect blockages or narrowing in heart arteries—often recommended for chest pain, abnormal stress tests, or cardiac risk assessment—with costs typically ranging ¥1,000–¥3,000 in China, and ChinaMedicalHub assists with hospital booking and interpreter support.
Main Uses
The primary purpose of a Coronary Artery CTA is to evaluate the patency and condition of the coronary arteries. It is used for diagnosing coronary artery disease, assessing the extent and severity of atherosclerotic plaques, planning treatment strategies, and evaluating the results of interventions like stenting or bypass surgery. It is also useful in patients presenting with chest pain or other symptoms suggestive of coronary artery disease, and for preoperative assessment before non-cardiac surgeries.
Normal Range
For a Coronary Artery CTA, the normal range typically indicates no significant stenosis (narrowing) or blockages in the coronary arteries. The degree of stenosis is usually reported as a percentage, with less than 50% considered non-obstructive and generally within the normal range.
Low Values - Possible Causes
Low values or findings in a Coronary Artery CTA, indicating minimal to no stenosis, can be due to: healthy lifestyle, effective management of cardiovascular risk factors, genetic predisposition to good heart health, recent successful intervention such as angioplasty or bypass surgery, or the presence of naturally wide coronary arteries.
High Values - Possible Causes
High values or abnormal findings, indicating significant stenosis or blockages, can be caused by: atherosclerosis (buildup of plaque in the arteries), coronary artery disease, high blood pressure, diabetes, smoking, or high cholesterol levels.
