Introduction. Evidence on survival benefits of percutaneous coronary intervention (PCI) in patients with severe ischemic left ventricular systolic dysfunction (ILVD) is scant. The REVIVED trial showed that, compared to optimal medical therapy (OMT), revascularisation by PCI did not reduce the incidence of death from any cause or heart failure hospitalization (HF); it also failed to provide sustained improvements in health-related quality of life. REVIVED data are used to evaluate the economic consequences and health outcomes of PCI+OMT and OMT alone in HF patients in the UK.

Methods. 700 patients with ILVD were randomised to either PCI+OMT or OMT. Healthcare resource use and patient-reported health outcomes data EuroQol on each patient were collected at baseline and over a period of 8 years post randomisation (median follow up of 3.5 years). Health resources were costed using publicly available national unit costs from the perspective of the UK health system. Within trial mean total costs and quality adjusted life years (QALYs) were estimated and incremental cost effectiveness was evaluated. Regression analysis on total costs and total QALYs was used to adjust for clinically relevant baseline covariables. Probabilistic sensitivity analysis was used to reflect parameter uncertainty.

Results. Statistical modelling identified gender, BMI, hypertension, diabetes, NYHA grade and previous hospitalisation as the most relevant baseline predictors of costs and benefits. Over the 8 years of fu, patients undergoing PCI yielded, on average, similar health benefits (4.13 QALYs IC [4.10 - 4.16]) at higher costs (£14,674 IC[£14,334 - £15,014]), compared to OMT (4.16 QALYs [4.13 - 4.19]; £5154 IC [£5,034 - £5,273]).

Conclusion. We found no difference in total QALYs between arms and PCI+OMT was not cost-effective compared to OMT, given its additional costs. Therefore, a strategy of routine PCI to treat ILVSD does not appear to be a justifiable use of healthcare resources.
