BACKGROUND The present study investigated whether preoperative angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) use affected the incidence of postoperative atrial fibrillation (POAF) in patients undergoing off-pump coronary artery bypass graft (OPCAB). HYPOTHESIS Preoperative use of ACEI or ARB was related to POAF in(More)
BACKGROUND Several studies have shown in animal models that remote ischemic preconditioning (rIPC) has a neuroprotective effect. However, a randomized controlled trial in human subjects to investigate the neuroprotective effect of rIPC after cardiac surgery has not yet been reported. Therefore, we performed this pilot study to determine whether rIPC reduced(More)

BACKGROUND Chronic and acute anemia are both correlated with an increased risk of injury to major organs, such as the brain, heart, and kidney. We evaluated the association between postoperative anemia (hemoglobin [Hb] < 10 g/dL) and acute kidney injury (AKI) in patients undergoing total hip replacement arthroplasty (THRA). METHODS Patients who underwent(More)
BACKGROUND The ratio of early transmitral flow velocity to early diastolic velocity of the mitral annulus (E/e') correlates with left ventricular (LV) filling pressure. In particular, an E/e' ratio more than 15 is an excellent predictor of increased LV filling pressure. The authors evaluated the prognostic implications of preoperative estimated LV filling(More)
To investigate the association between preoperative low serum albumin level and acute kidney injury (AKI) after off-pump coronary artery bypass surgery (OPCAB) We assessed preoperative and perioperative risk factors, and preoperative serum albumin concentration in 1,182 consecutive adult patients with preoperative normal renal function who underwent OPCAB(More)

It has been previously known that low-dose atropine (LDA) enhances vagal outflow to the heart. To demonstrate the importance of vagal cardiac modulation in arterial blood pressure (ABP) stability, we evaluated the effect of vagal cardiac stimulation with administration of LDA on ABP fluctuation during dynamic hypertensive and hypotensive stimuli. We(More)
