Single-cycle Remote Ischemic Preconditioning and Postconditioning (SCRIP) Trial

Incidence of myocardial injury

Incidence of myocardial injury defined as \> 5 times elevation of cardiac troponin from baseline in patients with normal baseline troponin and elevation of cardiac troponin \> 20% in patients who have elevated baseline troponin (\>99 percentile upper reference limit).

Time frame: within 24 hours

Major adverse cardiovascular events (MACE) in each intervention group

MACE = composite of CV death, MI, stroke, repeat revascularization, hospitalization for heart failure.

Time frame: 6 months

Incidence of myocardial injury in differrent subgroups of patient characteristics

Patient characteristics include sex, age, underlying disease, medications, indication for PCI (ACS and elective PCI), baseline cardiac enzyme and creatinine. Incidence of myocardial injury defined as \> 5 times elevation of cardiac troponin from baseline in patients with normal baseline troponin and elevation of cardiac troponin \> 20% in patients who have elevated baseline troponin (\>99 percentile upper reference limit).

Time frame: within 24 hours

Incidence of myocardial injury in patients with vs. without RIPre and RIPost

Myocardial injury defined as \> 5 times elevation of cardiac troponin from baseline in patients with normal baseline troponin and elevation of cardiac troponin \> 20% in patients who have elevated baseline troponin (\>99 percentile upper reference limit).

Time frame: 24 hours

Incidence of MACE in differrent subgroups of patient characteristics

Patient characteristics include sex, age, underlying disease, medications, indication for PCI (ACS and elective PCI), baseline cardiac enzyme and creatinine. MACE = composite of CV death, MI, stroke, repeat revascularization, hospitalization for heart failure.
