This randomized controlled trial investigated the prognostic value of radial wall strain (RWS) in predicting cardiac events in non-target vessels after percutaneous coronary intervention. Analyzing data from 1,551 patients, the study found that a baseline RWS max ≥13% independently predicted a non-target vessel-oriented composite endpoint (NT-VOCE) with an adjusted hazard ratio of 4.82 (95% CI: 3.14-7.40; p<0.0001).
Key findings
- Baseline RWS max ≥13% predicted NT-VOCE with an adjusted HR of 4.82 (95% CI: 3.14-7.40; p<0.0001).
- The adjusted area under the curve for RWS was 0.73 (95% CI: 0.69-0.78; p<0.0001).
- In high-quality angiographic images, RWS showed an adjusted HR of 6.89 (95% CI: 3.15-15.07; p<0.0001) for NT-VOCE.
Why it matters
Understanding the prognostic value of RWS can help clinicians identify patients at higher risk for adverse cardiovascular events, potentially guiding more tailored follow-up and intervention strategies.
