Abstract
BACKGROUND: Cardiovascular surgery is one of the highest risk procedures in the field of surgery. Preoperative assessment of endothelial function has been reported as useful for predicting postoperative adverse events (AEs). The aim of this study was to investigate the relationship between endothelial function assessed by reactive hyperemia index (RHI) and AEs after cardiovascular surgery.Methods and Results:A prospective observational study of 197 patients who underwent cardiovascular surgery was conducted. RHI was measured before the surgery. The primary endpoint was a composite of postoperative death, reoperation, stroke, newly required dialysis, deep sternum infection, and prolonged ventilation within 30 days. The secondary endpoint was new-onset atrial fibrillation (AF) within 30 days. Following cardiovascular surgery, 19 patients (9.6%) had AEs. New-onset AF was documented in 42 (25.9%) of 162 patients without a prior history of AF. In the receiver-operating characteristic curve analysis, RHI significantly predicted AEs (area under the curve [AUC] 0.67, best cutoff value 1.64, P=0.03), whereas RHI did not predict new-onset AF (AUC 0.53, P=0.93). Patients with RHI ≤1.64 had more AEs than those with RHI >1.64 (16.3% vs. 4.5%, P=0.005). Multiple logistic regression analysis showed the number of surgical procedures and RHI ≤1.64 as significant predictors of AEs. CONCLUSIONS: Preoperative endothelial dysfunction assessed by RHI was associated with postoperative AEs in patients with cardiovascular surgery.

Atrial fibrillation (AF) is a common cardiac arrhythmia affecting >30 million persons worldwide.1 In addition, AF increases the risk of stroke, heart failure, and overall mortality.2 With the aging of the population, the incidence and prevalence of AF are expected to grow in future decades as well as the burden from its associated complications.3 The growing public health significance of AF has spurred efforts to identify individuals at higher risk of developing this arrhythmia and its complicat...

BackgroundAtrial fibrillation after cardiac surgery is associated with increased rates of death, complications, and hospitalizations. In patients with postoperative atrial fibrillation who are in stable condition, the best initial treatment strategy — heart-rate control or rhythm control — remains controversial. MethodsPatients with new-onset postoperative atrial fibrillation were randomly assigned to undergo either rate control or rhythm control. The primary end point was the total number of da...

Background Endothelial dysfunction plays a pivotal role in cardiovascular disease progression, and is associated with adverse events. The purpose of this systematic review and meta‐analysis was to investigate the prognostic magnitude of noninvasive peripheral endothelial function tests, brachial artery flow‐mediated dilation (FMD), and reactive hyperemia–‐peripheral arterial tonometry (RH‐PAT) for future cardiovascular events. Methods and Results Databases of MEDLINE, EMBASE, and the Cochrane Li...

Hemostasis encompasses a set of tightly regulated processes that govern blood clotting, platelet activation, and vascular repair. Upon vascular injury, the hemostatic system initiates a series of vascular events and activates extravascular receptors that act in concert to seal off the damage. Blood clotting is subsequently attenuated by a plethora of inhibitors that prevent excessive clot formation and eventual thrombosis. The endothelium which resides at the interface between the blood and surr...

Objective—It is unknown whether endothelial dysfunction precedes atrial fibrillation (AF) development. The objective of this study was to examine the association of brachial flow-mediated dilation (FMD) with incident AF. Approach and Results—A total of 2936 participants (mean age, 61±9.9 years; 50% women; 66% nonwhites) from the Multi-Ethnic Study of Atherosclerosis with available ultrasound brachial FMD measurements who were free of baseline AF were included in this analysis. Baseline (2000–200...

Background Atrial fibrillation (AF) remains the most common complication after cardiac surgery. The present study aim was to derive an effective bedside tool to predict postoperative AF and its related complications. Methods and Results Data of 17 262 patients undergoing adult cardiac surgery were retrieved at 3 European university hospitals. A risk score for postoperative AF (POAF score) was derived and validated. In the overall series, 4561 patients (26.4%) developed postoperative AF. In the d...

Background: Venous thromboembolism (VTE) is a common and sometimes lethal postoperative complication of arthroplasty. Endothelial dysfunction is important in the pathogenesis of thrombus formation. Reactive hyperemia-peripheral arterial tonometry (RH-PAT) can noninvasively evaluate endothelial function. This study investigated the predictive value of RH-PAT for deep vein thrombosis (DVT) after lower limb arthroplasty. Methods and Results: A prospective observational study of 126 osteoarthritic p...

BACKGROUND: Simple office-based counseling for diet and exercise does not appear to positively affect success rates in metabolic syndrome (MetS) patients. The utility of the lifestyle modification self-assessment score (Self-AS) in the improvement of endothelial function by office-based counseling for patients with MetS was investigated. METHODS AND RESULTS: Patients with MetS (n=207) and age- and sex-matched individuals without MetS (n=124) were enrolled in this cross-sectional study. Endotheli...

Elevated serum uric acid level was reportedly associated with greater coronary lipid plaque. Xanthine oxidoreductase (XOR) is a rate-limiting enzyme in purine metabolism and believed to play an important role in coronary atherosclerosis. However, the relation of XOR to coronary lipid plaque and its mechanism are unclear. Patients with stable coronary artery disease undergoing elective percutaneous coronary intervention under near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS) guidanc...

BACKGROUND Endothelial dysfunction seems to play a role in the pathophysiology of myocardial injury after surgery. The aim of this randomised clinical trial was to examine whether remote ischaemic preconditioning in relation to hip fracture surgery ameliorates post-operative systemic endothelial dysfunction. METHODS This was a planned single-centre pilot sub-study of a multicentre, randomised clinical trial. Patients ≥45 years with a cardiovascular risk factor were randomised to remote ischaemic...

We recently reported that preoperative endothelial dysfunction [i.e., reactive hyperemia index (RHI) ≤ 1.64] predicted short-term postoperative adverse events in patients undergoing cardiovascular surgery. However, the relationship between preoperative RHI and long-term cardiovascular risk in these patients is unclear. A total of 195 patients with at least 1-year follow-up who underwent cardiovascular surgery were included. Preoperative endothelial function was assessed by RHI. The primary outco...
