Prediction of Recurrent Events With 18F-Fluoride (PREFFIR)
June 10, 2022 updated by: University of Edinburgh
Prediction of Recurrent Events With 18F-Fluoride to Identify Ruptured and High-risk Coronary Artery Plaques in Patients With Myocardial Infarction
This is a multi-centre observational study.
It will make use of the positron emission tomography (PET) tracer 18F-sodium fluoride (18F-NaF) as a marker of coronary plaque vulnerability to detect culprit and non-culprit unstable coronary plaques in patients with recent myocardial infarctions.
The investigators will then perform long-term follow-up of these patients to determine the prognostic significance of coronary 18F-NaF uptake
Study Overview

Conditions
Detailed Description
The investigators intend to recruit 700 patients hospitalised with myocardial infarction and proven multivessel coronary artery disease.
All patients will undergo a combined CT coronary angiogram (CTCA) and PET scan using 18F-NaF as a tracer.
Patients will then have clinical follow-up before undergoing a repeat CTCA at 2 years to assess progression of coronary disease.
Clinical review of all patients will continue until study completion (given 2 years of recruitment this is likely to last 4 years) and following this the investigators will continue to monitor for further cardiovascular events via review of patient electronic health records for a further 5 years.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Cardiac death, non-fatal recurrent myocardial infarction or unscheduled coronary revascularisation

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
All cause death
Time Frame: 2 years
|
2 years
|
|
Recurrent major adverse cardiac events defined as cardiac death, recurrent myocardial infarction, and rehospitalization for acute coronary syndrome, unscheduled coronary revascularization
Time Frame: 2 years
|
2 years
|
|
Healthcare resource utilization of patients with and without focal 18F-NaF uptake in coronary plaques unrelated to index myocardial infarction
Time Frame: 2 years

|
2 years
|
Each individual component end-point of the composite end-point of major adverse cardiac event
Time Frame: 2 years
|
2 years
|
|
18F-NaF uptake localisation to culprit plaque causing the index myocardial infarction
Time Frame: 3 weeks
|
Whether 18F-NaF uptake localises to the culprit plaque responsible for the index myocardial infarction
|
3 weeks
|
Territory of subsequent myocardial reinfarction in patients with focal 18F-NaF uptake in coronary plaques unrelated to index myocardial infarction
Time Frame: 2 years
|
Whether there is detectable 18F-NaF uptake in coronary plaques which are not the culprit related to the index MI but are potentially the cause of subsequent MI as determined by the territory of the subsequent MI corresponding with myocardium supplied by the artery with initial 18F-NaF uptake
