BACKGROUND: Even after complete revascularization (CR), patients with acute myocardial infarction (AMI) still face significant risks of adverse events, frequently linked to vulnerable plaque progression in nonsignificant stenosis.
AIMS: To investigate the relationship between the radial wall strain (RWS) of nonsignificant stenosis lesions and major adverse cardiac events (MACE) in patients with AMI following CR.
METHODS: This cohort study included patients with AMI who received CR of all culprit and non-culprit lesions with diameter stenosis (DS%) > 70% during index or staged percutaneous coronary intervention within 45 days, with at least one de novo native lesion (DS% of 30%-70%) for RWS analysis. The primary outcome was MACE comprising cardiovascular death, nonfatal myocardial infarction, unstable angina, and heart failure.
RESULTS: During a median follow-up of 3.6 years, 55 among 225 patients (24.4%) experienced MACE, mainly driven by unstable angina. Maximum RWS (RWSmax) was predictive of MACE with an area under the curve of 0.84 (95% CI: 0.78-0.90; p < 0.001) and an optimal cutoff > 14.5%. In the multivariable Cox regression model, RWSmax > 14.5% was an independent predictor for MACE among patients with AMI after CR (HR: 8.06; 95% CI: 3.98-16.35; p < 0.001). In patients with Murray law-based quantitative flow ratio (μQFR) > 0.8, the prognostic impact of RWSmax on MACE was comparable to that observed in patients with μQFR < 0.8 (P for interaction = 0.236).
CONCLUSIONS: Among patients with AMI who received CR, a high-strain pattern detected by RWS analysis in nonsignificant stenosis lesions was associated with a worse clinical outcome.
