Large randomized controlled trials in perioperative cardiovascular medicine: a proposal for the design, conduct and efficient management.

The number of patients undergoing noncardiac surgery is growing worldwide. To optimally assist patients during the perioperative period, we must improve our knowledge of how to prevent major perioperative cardiovascular events around the time of noncardiac surgery. To achieve this goal there is a need for large randomized controlled trials that can provide reliable and conclusive results in this field. This narrative review describes a proposal for the design, conduct and management of large controlled trials in perioperative cardiovascular medicine.
