Early Prediction of QFR in STEMI-Pharmaco-invasice (EARLYmyoQFR-PI)

Detailed Description
Microvascular dysfunction (MVD) is a serious complication of PCI, which happens frequently after STEMI and always correlates with a poor prognosis. However, precise and simplified assessment of MVD is difficult, especially in the acute phase of STEMI patients. Resent studies suggested that FFR could be overestimated when MVD exists. But whether the overestimated value of FFR caused by CMR defined MVO could reflect microcirculation function is still unclear.
This study is a retrospective study using STEMI patients who underwent pharmaco-invasive strategy as the population. Contrast-enhanced CMR was performed 5 days after PCI as the reference standard.

Description
Inclusion Criteria:
- STEMI patients treated with revasculation within 12 hours from onset of symptoms to PCI time and received CMR 5 days afterwards. STEMI was defined as a combination of the following: chest pain for more than 30min, electrocardiographic (ECG) changing with ST segment elevation of >2 mm in at least 2 precordial leads and >1 mm in limb leads, and abnormal troponin levels or CKMB levels higher than twice the upper limit of normal.
- Patients underwent successfully pharmaco-invasive strategy with half-dose alteplase.
Exclusion Criteria:
- Patients with left bundle branch block in the presenting ECG, cardiogenic shock, PCI or bypass surgery history.
- Patients with residual stenosis <50%.
- Patients with unqualified coronary angiographic images with problems such as ostial lesion, severe vessel tortuosity and diffuse long lesions.

Cohorts and Interventions

Intervention / Treatment |
---|---|
MVO group
CMR was performed in all the cases.
According to the results of CMR, we divided the study population into MVO group and Non-MVO group.
|
Computation of QFR was performed offline, using AngioPlus system(Pluse medical imaging technology, Shanghai, China).
In the first step, 2 diagnostic angiographic projections before PCI, at least 25° apart, were selected and 3D reconstruction of the interrogated vessel without its side branches was performed.
Then, the software computed the QFR.

Non-MVO group
CMR was performed in all the cases.
According to the results of CMR, we divided the study population into MVO group and Non-MVO group.

TIMI Flow Grade (TFG)
Time Frame: One mins before PCI

TIMI Flow Grade (TFG) assesses flow in the epicardial arteries.
Type zero perfusion expressed not antegrade movement away the occlusion; type two is a minimum, inadequate perfusion of contrast average round the mass; type three (partial perfusion) is a perfect just limited perfusion from the distal coronary bed by contrast element; and type three (complete perfusion) is an antegrade movement to the whole distal artery at a regular flow.
