Do traditional clinical cardiovascular risk factors predict the presence of high-risk atherosclerotic plaques on coronary computed tomography in patients with suspected CAD?
Traditional cardiovascular risk factors do not predict the presence of high-risk atherosclerotic plaques on CCT, suggesting that clinical risk estimation alone may miss high-risk patients.
Background: Cardiovascular (CV) risk estimation is usually based on the assessment of classic risk factors and the extent of coronary artery stenosis. However, a substantial rate of acute coronary syndromes (ACS) and sudden cardiac deaths (SCD) is observed in patients with high-risk atherosclerotic plaques (HRP), even in the absence of significant stenosis. Therefore, this study aimed to evaluate the predictive value of traditional clinical risk factors for the presence of HRP in patients scheduled for coronary computed tomography (CCT). Methods: This single-center study included 123 patients undergoing CCT for suspected coronary artery disease (CAD). Atherosclerotic plaque morphology (HRP) and the degree of coronary artery stenosis (CAD-RADS categories) were assessed in all the patients. CV risk factors, including LDL serum levels and CT Calcium score (CS), were analyzed. Results: The study cohort was mostly males (54.5%), with an average age of 60.40 ± 12.45 years and typical risk factors: hypertension (70%), diabetes (22%), obesity (30%), and smoking (20%). Most patients (88%) were found to have coronary atherosclerosis with nonobstructive disease (CAD-RADS 1–2) in 39% of patients. HRP was confirmed in over one-fifth of the participants (22%), with half of the patients in the CAD-RADS 2 category. There were no differences in CV risk factors between patients with and without HRP in CCT. No significant clinical predictor of HRP in CCT was identified. Conclusions: CV risk factors do not predict HRP in CCT, which may underestimate the real risk of ACS and SCD.
Żarczyński et al. (Thu,) conducted a cross-sectional in Suspected coronary artery disease (CAD) (n=123). Traditional cardiovascular risk factors was evaluated on Presence of high-risk atherosclerotic plaques (HRP). Traditional cardiovascular risk factors did not significantly predict the presence of high-risk atherosclerotic plaques in patients undergoing coronary computed tomography.
