The PRECISE trial examined coronary atherosclerosis characteristics in 737 patients with stable suspected coronary artery disease (CAD) using coronary computed tomography angiography (CCTA) and fractional flow reserve computed tomography (FFR-CT). The study found that total plaque volume was highest in patients with combined focal and diffuse CAD (DIFFOC) at 262 mm³, and revascularization was performed in about 51% of focal CAD patients.
Key findings
- Total plaque volume was highest in DIFFOC patients at 262 [175-504] mm³.
- Revascularization rates were 51% for focal CAD and 49% for combined focal and diffuse CAD.
- Typical angina was reported more frequently in focal CAD patients (p = 0.04).
- Only 2% of patients with <50% stenosis underwent revascularization.
Why it matters
Understanding the characteristics of CAD, including diffuseness and focality, can help clinicians better assess patient management and treatment strategies, particularly regarding revascularization decisions.
