Insights
Stable patients with multiple cardiovascular risk factors commonly have severe coronary artery lesions. Early detection using computed tomography angiography is valuable for identifying these high-risk individuals.
Area of Science:
- Cardiology
- Radiology
- Preventive Medicine
Background:
- Multiple cardiovascular risk factors increase the likelihood of coronary artery disease.
- Early identification of coronary artery lesions is crucial for preventing adverse cardiovascular events.
- Stable patients with multiple risk factors represent a key population for screening.
Purpose of the Study:
- To determine the prevalence, extent, severity, and characteristics of coronary artery lesions.
- To compare coronary lesion features between patients with multiple risk factors and controls.
- To evaluate the utility of computed tomography angiography in assessing coronary lesions.
Main Methods:
- Seventy-seven patients with >3 cardiovascular risk factors and 39 controls were enrolled.
- Risk factors included hypertension, impaired glucose tolerance, dyslipidemia, smoking, and overweight.
- 64-slice coronary computed tomography angiography was used to evaluate coronary lesions.
Main Results:
- Coronary atherosclerosis incidence was significantly higher in the high-risk group.
- Coronary lesions were more severe in the high-risk group regarding involved branches, lesion diffusivity, stenosis degree, and plaque nature (p < 0.05).
Conclusions:
- Early coronary artery lesions are prevalent and severe in stable individuals with multiple cardiovascular risk factors.
- Computed tomography angiography shows promise for early screening and detection of coronary lesions in this population.
Objectives:
To investigate the prevalence, extent, severity, and features of coronary artery lesions in stable patients with multiple cardiovascular risk factors.
Methods:
Seventy-seven patients with more than 3 cardiovascular risk factors were suspected of having coronary artery disease. Patients with high-risk factors and 39 controls with no risk factors were enrolled in the study. The related risk factors included hypertension, impaired glucose tolerance, dyslipidemia, smoking history, and overweight. The characteristics of coronary lesions were identified and evaluated by 64-slice coronary computed tomography angiography.
Results:
The incidence of coronary atherosclerosis was higher in the high-risk group than in the no-risk group. The involved branches of the coronary artery, the diffusivity of the lesion, the degree of stenosis, and the nature of the plaques were significantly more severe in the high-risk group compared with the no-risk group (all p < 0.05).
Conclusion:
Among stable individuals with high-risk factors, early coronary artery lesions are common and severe. Computed tomography has promising value for the early screening of coronary lesions.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
