Conditions: Myocardial Infarction

Registration Number: NCT01399736

Lead Sponsor: Maasstad Hospital

Brief Summary: The Compare-Acute trial is a prospective randomised trial in patients with multivessel disease, who are admitted into hospital with a ST-elevation Myocardial Infarction. The purpose of the study is to compare a FFR guided multivessel PCI taking place during the primary PCI with a primary PCI of the culprit vessel only.

Patients will be enrolled after successful revascularisation of the culprit vessel. Patients that have at least one lesion with a diameter of stenosis of more than 50% on visual estimation, feasible (operators judgement) for treatment with PCI in a non-infarct related artery, will be randomised either to the FFR guided complete revascularisation arm or staged revascularisation by proven ischemia or persistence of symptoms of angina.

Approximately 885 patients will be entered in the study.

Study hypothesis: FFR-guided complete percutaneous revascularisation of all flow-limiting stenoses in the non-IRA performed within the same procedure as the primary PCI or within the same hospitalisation will improve clinical outcomes compared to the staged revascularisation, guided by prove of ischemia or clinical judgment, as recommended from the guidelines.

Detailed Description: Background of the study: At the moment the general opinion is divided over the way the non culprit lesions in patients presenting with STEMI should be treated. While the previous guidelines stead that these lesions should be treated in a second time ( ie not during the primary intervention) the actual guidelines do not touch this argument. The reason is that the studies where the previous guidelines were based are old. Meanwhile small sized randomised trials from EU region have proven favourable outcomes with NON infarct related artery during the primary procedure while registers (non randomised trials) from USA still recommend the staged treatment. For this reason we have decided to perform a randomised study to address this issue incorporating the state of the art diagnosis and treatment, as well as the new medical therapy and PCI techniques.

Objective of the study: FFR-guided complete percutaneous revascularisation of all flow-limiting stenoses in the non-IRA performed within the same procedure as the primary PCI or within the same hospitalisation will improve clinical outcomes compared to the staged revascularisation, guided by prove of ischemia or clinical judgment, as recommended from the guidelines

Study design: Prospective, 1: 2 randomisation. FFR guided revascularisation during primary PCI (1) versus following actual guidelines (2)

Study population: All STEMI patients between 18-85 years who will be treated with primary PCI in \< 12 h (more than 12 hr if persisting pain allowed) after the onset of symptoms and have at least one stenosis of \>50% in a non-IRA judged feasible for treatment with PCI.

Intervention (if applicable): FFR-guided complete percutaneous revascularisation of all flow-limiting stenoses in the non-IRA performed within the same procedure as the primary PCI or within the same hospitalisation will improve clinical outcomes compared to the staged revascularisation, guided by prove of ischemia or clinical judgment, as recommended from the guidelines

Primary study parameters/outcome of the study: Composite endpoint of all cause mortality non-fatal Myocardial Infarction, any Revascularisation and Stroke (MACCE) at 12 months

Arm && Interventions

Group	Intervention	Description
FFR-guided revascularisation strategy	FFR-guided revascularisation strategy	In the FFR-group all flow limiting (FFR≤0.80) lesions will receive treatment by PCI and stenting. The non-IRA PCI should be performed during the same intervention. Exceptions can be made for complex lesions where the operator estimates that the revascularisation procedure will require significant contrast overload which may lead to deterioration of cardiac and renal function of the patient. Such procedures can be performed in a second procedure which should take place within the same hospitalisation. All lesions with a FFR measurement of \>0.80 will not be treated.
randomised to guidelines group	randomised to guidelines group	In the randomised to guidelines group the procedure will stop after the FFR measurements and the patient will be referred to his treating cardiologist who will decide whether a staged PCI of the non-IRA artery should take place. The treating cardiologist will be blinded for the FFR measurements (but not angiographic imaging) and must make a decision based on conventional non-invasive ischemia detecting tests or clinical signs and symptoms i.e. very typical angina symptoms in patients with angiographic significant stenosis).
