Randomized Controlled Trial Clinical TrialThe value of preoperative pharmacologic stress testing before vascular surgery using ACC/AHA guidelines: a prospective, randomized trial.
To evaluate the validity of preoperative cardiac stress testing using clinical predictors from the American College of Cardiology/American Heart Association Guidelines on Perioperative Evaluation before Noncardiac Surgery in patients undergoing vascular surgery. ⋯ In this small prospective, randomized study evaluating the validity of preoperative cardiac stress testing using ACC/AHA Guidelines before major vascular surgery, preoperative cardiac stress testing offered no incremental value for determining postoperative adverse cardiac outcomes. Larger randomized clinical trials are needed to confirm these findings.

Comparative StudyA comparison of CardioQ and thermodilution cardiac output during off-pump coronary artery surgery.
To compare CardioQ esophageal Doppler cardiac output and thermodilution cardiac output during off-pump coronary artery bypass surgery. ⋯ Because of the wide limits of agreement and the large interpatient differences in both bias and precision, the CardioQ esophageal Doppler cardiac output cannot currently be recommended as an alternative to thermodilution cardiac output during off-pump coronary artery bypass surgery.
