Remote ischemic preconditioning has a neutral effect on the incidence of kidney injury after coronary artery bypass graft surgery.

Acute kidney injury (AKI) is a frequent complication of cardiac surgery and usually occurs in patients with preexisting chronic kidney disease (CKD). Remote ischemic preconditioning (RIPC) may mitigate the renal ischemia-reperfusion injury associated with cardiac surgery and may be a preventive strategy for postsurgical AKI. We undertook a randomized controlled trial of RIPC to prevent AKI in 86 patients with CKD (estimated glomerular filtration rate under 60 ml/min per 1.

Impact of diabetes mellitus and renal insufficiency on 5-year mortality following coronary artery bypass graft surgery: a cohort study of 4869 UK patients.

Objectives: Diabetes mellitus (DM) and renal impairment (RI) are both independent predictors of mortality after coronary artery bypass graft surgery (CABG). The two conditions often coexist, yet the impact on long-term prognosis after CABG of each factor relative to the other and the two in combination is uncertain.

Methods: We undertook a prospective cohort study of 4869 patients who underwent CABG between 2003 and 2007.

The impact of acute kidney injury on midterm outcomes after coronary artery bypass graft surgery: a matched propensity score analysis.

Background: The development of acute kidney injury (AKI) after coronary artery bypass graft (CABG) surgery is associated with increased short- and long-term mortality. Whether AKI has a causal relationship with subsequent mortality or whether the development of AKI simply occurs in patients with more comorbidity undergoing more complex procedures remains unresolved.

Methods And Results: This was an observational cohort study of prospectively collected data from 4694 patients discharged from the hospital after first-time CABG surgery at a tertiary cardiac center between 2003 and 2008.

Diagnosis and management of patients with acute cardiac symptoms, troponin elevation and culprit-free angiograms.

Patients with acute cardiac symptoms, elevated cardiac troponin and culprit-free angiograms comprise a significant proportion of patients admitted with presumed acute coronary syndromes (ACS). International guidelines recommend that these patients receive lifelong secondary prevention under the presumption that angiographically undetectable coronary artery disease is the likeliest cause for their presentation. Recent studies using cardiac MRI suggest myocarditis to be the most common cause of these presentations.
