Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In patients with ST elevation myocardial infarction (STEMI) the treatment goal is revascularization of the occluded artery with the use of primary percutaneous coronary intervention (PCI). There is a large subset of patients with STEMI who also have significant disease in arteries other than the site of occlusion, and away from the culprit artery. It is estimated that up to 50% have disease of more than 50% in the non-culprit arteries.

The evidence on how to treat those patients with multi vessel disease is conflicting. Earlier large-scale studies and registries have suggested early and complete revascularization is of no benefit or even harmful. More recent studies have showed the opposite of that. The CVLPRIT study showed that early complete revascularization or preventive PCI reduced primary endpoint of a composite of all cause mortality, myocardial infarction and need for repeat revascularization. The benefit was mainly due to reduced repeat revascularization in the more intensive intervention group. The PRAMI study showed very similar results as well.

The use of Fractional flow Reserve (FFR) in deciding complete revascularization has also showed conflicting results so far. A previous trial showed that FFR guided intervention post STEMI increased MACE. This was conflicted with more recent study, which showed FFR guided complete revascularization improved outcome when compared with more conservative treatment of ischaemia driven intervention.

In this study, the investigators are going to assess the issue of staged revascularization guided by FFR or by angiogram, compared to the standard treatment of ischaemia driven revascularization

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To compare the clinical outcomes measured by composite of mortality, myocardial infarction and repeat revascularization by using FFR guided and angiographically guided revascularization to the standard strategy of ischaemia driven revascularization.

Participants will be allocated to three arms, first conservative group of ischaemia guided PCI, second FFR guided PCI and third angiogram guided PCI where patients where patients with more than 50% lesion will undergo revascularization.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Conservative

After the index primary PCI. The control group will receive best medical therapy and regular follow up and only PCI for recurrent angina with evidence of inducible ischaemia.

Group Type NO_INTERVENTION

No interventions assigned to this group

FFR guided

FFR group will undergo FFR at 4 weeks of the index primary PCI as OPD. If FFR is less than 0.8, then PCI will be performed

Group Type ACTIVE_COMPARATOR

FFR guided PCI

Intervention Type PROCEDURE

Patients undergo Fractional Flow measurement (FFR) followed by PCI, if the FFR is less than 0.8

angiogram guided

The group will undergo PCI for all significant lesions more than 50

Group Type ACTIVE_COMPARATOR

Angio guided PCI

Intervention Type PROCEDURE

Patients receive PCI without FFR measurement
