Study Objective: Our objective was to determine whether the systolic, diastolic, and mean arterial pressures measured in the radial artery accurately reflect corresponding pressures in the ascending aorta in narcotic-anesthetized patients with known obstructive coronary artery disease, before being subjected to cardiopulmonary bypass (CPB). Design: This was a prospective study. Setting: The cardiac operating room of a large, tertiarycare university medical center. Participants: Fifty-one patients (45 men and six women; age range, 48 to 77 years) with documented atherosclerotic coronary artery disease were studied. All patients underwent elective coronary artery bypass grafting after the study.
