Type of outcome measure | Outcome measures |
---|---|
CMRI parameters | ● IS (% total LV mass): Primary outcome |
● Incidence and extent of MVO (% LV mass) | |
● Myocardial salvage index (MSI) | |
● Intra-myocardial haemorrhage (IMH) | |
● LV ejection fraction (LVEF) and volumes | |
Angiographic markers of MVO | ● TIMI flow grade [87] |
● Computer-assisted myocardial blush quantification using the software ‘Quantitative Blush Evaluator’ (QuBE) [84] | |
● Incidence pre- and post-procedure of angiographic true ‘no-reflow’ | |
● Incidence of angiographic slow/no-reflow after P-PCI | |
ECG | |
Echocardiography | ● LV function at baseline and 3 months |
Sub-analyses | ● Comparing CMRI markers with other myocardial perfusion markers (angiographic, ECG and cardiac enzymes) |
● Overall MACE and its components at 1 month: death, need for TLR, recurrent MI, severe heart failure and CVE |
