Trial Outcomes & Findings for Clinical Evaluation of Magnetic Resonance Imaging in Coronary Heart Disease-2 (NCT NCT01664858)

NCT ID: NCT01664858

Last Updated: 2018-11-23

Results Overview

* A negative FFR and positive non-invasive test (either 3T CMR or SPECT/CCT) * A negative FFR in a high pre-test risk (61-90%) patient that proceeds directly to invasive angiography in the NICE guidelines-based strategy arm * A negative FFR and a negative non-invasive test (either 3T CMR or SPECT/CCT) (i.e. a True Negative strategy result in which the imaging result was 'not believed' by the treating cardiologist) * An inconclusive non-invasive test result (either 3T CMR or SPECT/CCT) in which angiography had to be performed to make the diagnosis

SECONDARY outcome

Timeframe: 3 years

To assess the long term cost-effectiveness of the alternate diagnostic testing strategies, information from the trial will be used to update the economic model developed as part of the original CE-MARC trial. The model will use information from the trial, including on resource use, costs, HRQoL and other clinical outcomes (e.g. on unnecessary tests and MACE events), together with epidemiological, clinical and economic data from other sources to calculate costs and quality-adjusted life-years (QALYs) for patients. The economic analysis will use methods consistent with those recommended by the National Institute for Health and Clinical Excellence (NICE). Given the potential difference between diagnostic strategies in terms of mortality, the modelling will adopt a lifetime time horizon to capture any difference.
