Eligible patients that are scheduled for an elective PCI or patients scheduled for a diagnostic catheterization procedure with orders of "treat as indicated" will be enrolled in the study. Patients will undergo remote ischemic conditioning with the autoRIC device or the control procedure with the autoRIC Sham device completed ≤ 1 hour prior to balloon or stent inflation. Subjects will have measurements of cTnI levels at baseline and 4-8 and 14-18 hours post completion of the PCI procedure. Adverse events will be recorded through study exit for all patients. Patients will be exited from the study after completion of their 30-day post-procedure telephone follow-up.
