Abstract

Background Use of intravascular ultrasound (IVUS) during percutaneous coronary intervention (PCI) is associated with improved clinical outcomes over angiography alone. Despite this, the adoption of IVUS in clinical practice remains low. Aims To examine the cost-effectiveness of IVUS-guided PCI compared to angiography alone in patients with acute coronary syndromes (ACS). Methods and results A 1-year decision tree and lifetime Markov model were constructed to compare the cost-effectiveness of IVUS-guided PCI to angiography alone for two hypothetical adult populations consisting of 1000 individuals: ST-elevation myocardial infarction (STEMI) and unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI) patients undergoing drug-eluting stent (DES) implantation. The United Kingdom (UK) healthcare system perspective was applied using 2019/20 costs. All-cause death, myocardial infarction (MI), repeat PCI, lifetime costs, life expectancy, and quality-adjusted life-years (QALYs) were assessed. Over a lifetime horizon, IVUS-guided PCI was cost-effective compared to angiography alone in both populations, yielding an incremental cost-effectiveness ratio of £3649 and £5706 per-patient in STEMI and UA/NSTEMI patients, respectively. In the 1-year time horizon, the model suggested that IVUS was associated with reductions in mortality, MI, and repeat PCI by 51%, 33%, and 52% in STEMI and by 50%, 29%, and 57% in UA/NSTEMI patients, respectively. Sensitivity analyses demonstrated the robustness of the model with IVUS being 100% cost-effective at a willingness to pay threshold of £20 000 per QALY-gained. Conclusions From a UK healthcare perspective, an IVUS-guided PCI strategy was highly cost-effective over angiography alone amongst ACS patients undergoing DES implantation due to the medium- and long-term reduction in repeat PCI, death, and MI.
