Descrizione
Inclusion Criteria:
- Patients aged ≥18 years
- Patients with suspected coronary artery disease (CAD) (e.g., chest pain syndrome or equivalent symptoms) who are evaluated with coronary computed tomography angiography (CCTA)
Coronary computed tomography angiography (CCTA) showing:
Plaque with at least moderate stenosis in one or more major epicardial coronary arteries; and
At least two high-risk plaque (HRP) feature at the site of stenotic lesions, defined as any of the following:
- Low-attenuation plaque (LAP) (<70 Hounsfield units)
- Positive remodeling (PR) (remodeling index >1.2)
- Napkin-ring sign (NRS)
- Spotty calcification (SC) (<3 mm in length)
- Willing and able to provide written informed consent
Exclusion Criteria:
- Acute coronary syndrome (ACS) requiring urgent or emergent invasive evaluation
- Hemodynamically unstable conditions
- Significant left main coronary artery disease (≥50% diameter stenosis)
- Coronary anatomy unsuitable for either percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG)
Left ventricular ejection fraction (LVEF) <35%
→ Left ventricular ejection fraction <35%
- New York Heart Association (NYHA) class III or IV heart failure at entry or hospitalization for exacerbation of chronic heart failure within the previous 6 months
- Prior coronary artery bypass grafting (CABG)
- Severe renal dysfunction (estimated glomerular filtration rate <30 mL/min/1.73 m²) or end-stage renal disease on dialysis
- Contraindication to undergoing coronary computed tomography angiography (CTA) (e.g., allergy to radiographic contrast that cannot be adequately premedicated, any prior anaphylaxis to radiographic contrast, or inability to cooperate with scan acquisition)
- Contraindications to or planned discontinuation of dual antiplatelet therapy within 1 year
- Life expectancy less than the duration of the trial due to non-cardiovascular comorbidity
- Planned cardiac or major noncardiac surgery within the study period
- Women who are breastfeeding, pregnant, or planning to become pregnant during the course of the study
- Inability to comply with the study protocol
- Active participation in another interventional clinical trial involving an unapproved investigational drug or device

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: Initial Invasive Strategy
|
Invasive coronary angiography (CAG) within 30 days after randomization, with the intent to perform preventive percutaneous coronary intervention (PCI) in addition to optimal medical therapy (OMT). For further detailed assessment of vulnerable plaque lesions detected by coronary computed tomography angiography, the use of intracoronary imaging modalities (near-infrared spectroscopy, optical coherence tomography, or intravascular ultrasound) will be strongly recommended. |
|
Comparatore attivo: Initial Conservative Strategy
|
Optimal medical therapy (OMT) alone, with invasive coronary angiography (CAG) reserved only for failure of optimal medical therapy, defined as recurrent or worsening symptoms despite maximally tolerated medical therapy, or the occurrence of an acute coronary event.

Economic evaluation of healthcare resource use, costs, and cost-effectiveness
Lasso di tempo: From baseline to 3 years; assessed at 1 month, 6 months, 1 year, 2 years, and 3 years
|
Healthcare resource utilization (including hospitalizations, procedures, and outpatient visits) will be collected and used to estimate total healthcare costs.
Cost-effectiveness will be assessed using the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life year (QALY) gained.
These components will be analyzed within a unified economic evaluation framework.
