Therefore, in this research study we investigate a new cheap treatment that may help protect the heart against damage during a heart attack, called remote ischemic conditioning (RIC), in which a blood pressure cuff is placed on the upper arm and inflated for 5 minute and deflated for 5 minutes a cycle which is repeated 4 times in total in patients presenting with a heart attack. By temporarily depriving oxygen and nutrients to the arm with the blood pressure cuff a protective signal can be relayed to the heart to reduce the amount of damage occurring during the heart attack and thereby prevent the onset of heart failure.
