1-Year Outcomes of FFRCT-Guided Care in Patients With Suspected Coronary Disease
2016
Abstract Background Coronary computed tomographic angiography (CTA) plus estimation of fractional flow reserve using CTA (FFR CT ) safely and effectively guides initial care over 90 days in patients with stable chest pain. Longer-term outcomes are unknown. Objectives The study sought to determine the 1-year clinical, economic, and quality-of-life (QOL) outcomes of using FFR CT instead of usual care. Methods Consecutive patients with stable, new onset chest pain were managed by either usual testing (n = 287) or CTA (n = 297) with selective FFR CT (submitted in 201, analyzed in 177); 581 of 584 (99.5%) completed 1-year follow-up. Endpoints were adjudicated major adverse cardiac events (MACE) …
Rationale and design of the Prospective LongitudinAl Trial of FFRCT: Outcome and Resource IMpacts study
2015
International audience; BACKGROUND: Fractional flow reserve (FFR) measured by coronary computed tomography angiography (FFRCT) has been validated against invasive FFR. However, there are no data on how the use of FFRCT affects patient care and outcomes. The aim of this study is to compare standard practice guided by usual care testing to FFRCT-guided management in symptomatic subjects with suspected coronary artery disease (CAD). METHODS: In this prospective nonrandomized trial, symptomatic patients with suspected CAD will be enrolled in 2 consecutive cohorts: a usual care-guided pathway (cohort 1) and an FFRCT-guided pathway (cohort 2). Each cohort is divided into 2 groups according to whe…

International audience; AIMS: In symptomatic patients with suspected coronary artery disease (CAD), computed tomographic angiography (CTA) improves patient selection for invasive coronary angiography (ICA) compared with functional testing. The impact of measuring fractional flow reserve by CTA (FFRCT) is unknown. METHODS AND RESULTS: At 11 sites, 584 patients with new onset chest pain were prospectively assigned to receive either usual testing (n = 287) or CTA/FFR(CT) (n = 297). Test interpretation and care decisions were made by the clinical care team. The primary endpoint was the percentage of those with planned ICA in whom no significant obstructive CAD (no stenosis \textgreater/=50% by …
Quality-of-Life and Economic Outcomes of Assessing Fractional Flow Reserve With Computed Tomography Angiography: PLATFORM.
2015
International audience; BACKGROUND: Fractional flow reserve estimated using computed tomography (FFRCT) might improve evaluation of patients with chest pain. OBJECTIVES: The authors sought to determine the effect on cost and quality of life (QOL) of using FFRCT instead of usual care to evaluate stable patients with symptoms suspicious for coronary disease. METHODS: Symptomatic patients without known coronary disease were enrolled into 2 strata based on whether invasive or noninvasive diagnostic testing was planned. In each stratum, consecutive observational cohorts were evaluated with either usual care or FFRCT. The number of diagnostic tests, invasive procedures, hospitalizations, and medi…
An FFR CT diagnostic strategy versus usual care in patients with suspected coronary artery disease planned for invasive coronary angiography at Germa…

Aim Diagnostic evaluation practices for suspected coronary artery disease (CAD) may vary between countries. Our objective was to compare a CT-derived fractional flow reserve (FFRCT) diagnostic strategy with usual care in patients with planned invasive coronary angiography (ICA) enrolled in the PLATFORM (Prospective Longitudinal Trial of FFRCT: Outcome and Resource Impacts) study at German sites. Methods Patients were divided into two consecutive observational cohorts, receiving either usual care or CT angiography (CTA)/FFRCT. The primary endpoint was the percentage of patients planned for ICA, with no obstructive CAD on ICA within 90 days. Secondary endpoints included death, myocardial infa…
