Background and objectives: Acute kidney injury is an independent predictor of short-and long-term survival; however, data on the relationship between reversible transitory decline of kidney function and chronic kidney disease (CKD) are lacking. We assessed the prognostic value of temporary renal function decline on the development of long-term CKD.Design, setting, participants, & measurements: The study included 1308 patients who were undergoing major vascular surgery (aortic aneurysm repair, lower extremity revascularization, or carotid surgery), divided into three groups on the basis of changes in Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) estimated GFR (eGFR) on days 1, 2, and 3 after surgery, compared with baseline: Group 1, improved or unchanged (change in CKD-EPI eGFR ؎10%); group 2, temporary decline (decline >10% at day 1 or 2, followed by complete recovery within 10% to baseline at day 3); and group 3, persistent decline (>10% decrease). Primary end point was the development of incident CKD during a median follow-up of 5 years.Results: Perioperative renal function was classified as unchanged, temporary decline, and persistent decline in 739 (57%), 294 (22%), and 275 (21%) patients, respectively. During follow-up, 272 (21%) patients developed CKD. In multivariate logistic regression analyses, temporary and persistent declines in renal function both were independent predictors of long-term CKD, compared with unchanged renal function.Conclusion: Vascular surgery patients have a high incidence of temporary and persistent perioperative renal function declines, both of which were independent predictors for development of long-term incident CKD.
The use of guideline recommended therapies in the perioperative period was associated with reduction in long-term mortality in patients with peripheral arterial disease. However, the proportion of patients receiving these evidence-based treatments-both at baseline and 3 years after vascular surgery-was lower than expected based on the current guidelines. These data highlight a clear opportunity to improve the quality of care in this high-risk group of patients.
Polyvascular atherosclerotic disease in PAD patients is independently associated with an increased risk for all-cause and cardiovascular mortality during long-term follow-up.
COPD is associated with increased carotid wall IMT independent of age and smoking status. Increased carotid wall IMT is associated with increased total and cardiovascular mortality in patients with COPD suggesting that carotid wall measurements may be a good biomarker for morbidity and mortality in these patients.
Asymptomatic cardiac damage in patients undergoing EVAR is associated with poor long-term outcome. Routine perioperative cardiac screening after EVAR might be warranted.
Transcatheter aortic valve implantation (TAVI) is an established treatment option for symptomatic patients with severe aortic valvular disease who are not suitable for conventional surgical aortic valve replacement. Despite improving experience and techniques, ischaemic and bleeding complications after TAVI remain prevalent and impair survival in this generally old and comorbid-rich population. Due to changing aetiology of complications over time, antiplatelet and anticoagulant therapy after TAVI should be carefully balanced. Empirically, a dual antiplatelet strategy is generally used after TAVI for patients without an indication for oral anticoagulation (OAC; e. g. atrial fibrillation, mechanical mitral valve prosthesis), including aspirin and a thienopyridine. For patients on OAC, a combination of OAC and aspirin or thienopyridine is generally used. This review shows that current registries are unfit to directly compare antithrombotic regimens. Small exploring studies suggest that additional clopidogrel after TAVI only affects bleeding and not ischemic complications. However, these studies are lack in quality in terms of Cochrane criteria. Currently, three randomised controlled trials are recruiting to gather more knowledge about the effects of clopidogrel after TAVI.
COPD was associated with increased risk for subclinical LV dysfunction. COPD+subclinical LV dysfunction was associated with increased risk for all-cause mortality compared to patients with COPD+normal LV function. Echocardiography may be useful to detect subclinical cardiovascular disease and risk-stratify COPD patients undergoing vascular surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
