Insights
Polyvascular atherosclerosis, affecting multiple vascular beds, is often underdiagnosed. Combined coronary, carotid, and cerebral computed tomography angiography (CCC CTA) with lipid profiling aids in early detection of this widespread disease.
Area of Science:
- Cardiovascular Medicine
- Radiology
- Preventive Cardiology
Background:
- Atherosclerosis commonly affects multiple vascular territories simultaneously, contributing to multimorbidity and adverse outcomes in aging populations.
- Current guidelines lack specific recommendations for detecting polyvascular disease, leading to underdiagnosis.
- Early, noninvasive screening is crucial for identifying widespread atherosclerosis.
Purpose of the Study:
- To evaluate the utility of combined coronary, carotid, and cerebral computed tomography angiography (CCC CTA) with lipid profiling for detecting polyvascular atherosclerosis.
- To assess the prevalence of atherosclerosis in coronary, extracranial carotid, and intracranial arteries.
- To explore the relationship between polyvascular disease and lipid profiles.
Main Methods:
- Subset analysis of a prospective registry (BHC-C, NCT05961748) including 719 Chinese patients.
- Patients underwent one-stop CCC CTA and comprehensive lipid profiling.
- Analysis included plaque prevalence, stenosis severity, and associations with lipid levels.
Main Results:
- Coronary atherosclerosis was most prevalent (80.7%), followed by extracranial carotid (77.9%) and intracranial (63.1%) plaques.
- Moderate-to-severe stenosis (≥50%) was found in 43.1% of coronary, 27.0% of extracranial carotid, and 26.6% of intracranial arteries.
- Notably, 8.7% of patients had concurrent involvement of all three vascular beds; these patients paradoxically showed lower LDL-C and Lp-PLA2 levels.
Conclusions:
- CCC CTA combined with lipid panel evaluation can help identify occult polyvascular atherosclerosis.
- This integrated approach allows comprehensive visualization of multi-bed plaques and risk factor assessment.
- The findings suggest potential for improved early detection and holistic management of polyvascular disease in primary and secondary prevention.
Background And Aims:
Coexisting atherosclerosis across vascular territories is a critical facet of multimorbidity in aging populations and is associated with adverse outcomes, yet it often remains underdiagnosed. Early identification through noninvasive screening is needed, given that atherosclerosis frequently affects polyvascular beds simultaneously and current guidelines lack specific recommendations for detecting polyvascular disease.
Methods And Results:
We performed a subset analysis of a prospective registry (BHC-C, NCT05961748) enrolling 719 Chinese patients (mean age 62 ± 11; 32.8% female) who underwent one-stop cerebral and carotid combined coronary (CCC) CTA plus comprehensive lipid profiling. Coronary atherosclerosis was most prevalent (80.7%), followed by extracranial carotid (77.9%) and intracranial (63.1%) plaques. Moderate-to-severe stenosis (≥50% luminal narrowing) was detected in 43.1%, 27.0%, and 26.6% of coronary, extracranial, and intracranial arteries, respectively. Notably, 11.8% of patients had triple-vessel coronary disease, and 8.7% exhibited concurrent intracranial, extracranial, and coronary involvement. Patients with polyvascular disease paradoxically showed lower LDL-C and Lp-PLA2 levels on average. This inverse cross-sectional association should be interpreted cautiously and may reflect prior ASCVD, intensive lipid-lowering or other preventive therapy, advanced disease stage, and residual confounding rather than a protective causal effect of lower Lp-PLA2.
Conclusions:
CCC CTA plus lipid panel evaluation may help reveal occult polyvascular atherosclerosis. This approach enabled comprehensive visualization of multi-bed plaques alongside risk factor assessment, demonstrating potential to improve early detection and holistic management of CCC comorbidity in both primary and secondary prevention settings.
