PeriOperative ISchemic Evaluation-2 Pilot

Major non-cardiac surgeries are common and major heart problems during or after such surgeries represent a large population health problem. Few treatments to prevent heart problems around the time of surgery have been tested. There is encouraging data suggesting that low-doses of Acetyl-Salicylic Acid (ASA) and Clonidine, which are two medications, given individually for a short period before and after major surgeries may prevent major heart problems.
