Is coronary angiography the same as coronary CT?

PCI Model

For angina pectoris patients with suspected coronary heart disease, whether to choose coronary CT or coronary angiography examination is a high-frequency question clinically.

What are the characteristics of coronary angiography?

Coronary angiography can directly reflect anatomical structure of coronary arteries and clarify presence of coronary artery disease.

Coronary angiography is known as the authoritative standard for diagnosis of coronary artery disease, but it is invasive and expensive due to its nature. The advantages are that reliable results and highly accurate. If it is diagnosed after testing, coronary balloon dilation, stent implantation, etc. can be performed immediately.

Coronary angiography can not only reflect the location and degree of stenosis of coronary arteries, but also observe effect of stenotic lesions on blood flow.

What are the characteristics of coronary CT?

The advantage of coronary CT is that it is non-invasive, low risk, and can be done on an outpatient basis. However, it does not truly reflect the degree of coronary stenosis, especially when stenosis is >70%. In addition, when coronary arteries are severely calcified, it can seriously affect doctor's judgment of the degree of stenosis.

Can low-risk, noninvasive coronary CT replace coronary angiography for some patients with suspected coronary heart disease?

The results of study showed that incidence of major adverse cardiovascular events was similar between coronary CT and coronary angiography groups, and the incidence of angina was similar in both groups, with no significant differences. The incidence of major procedure-related complications was lower in the coronary CT group.
