Acute Renal Failure following Cardiac Surgery: Pre- and Perioperative Clinical Features

Chronic Kidney Disease, Mortality, and Treatment Strategies among Patients with Clinically Significant Coronary Artery Disease

“…To be enrolled onto this study, patients had to be referred for cardiac catheterization. If referral for catheterization is affected by the presence of CKD because of concerns such as the risk of acute renal failure due to contrast nephrotoxicity (37)(38)(39)(40), the generalizability of these results to the entire population of patients with concurrent renal and cardiac disease may be affected. Furthermore, if the presence of CKD influences choice of revascularization strategy, it may introduce a bias that may also in turn affect outcomes.…”

Insuficiência renal aguda após cirurgia de revascularização miocárdica com circulação extracorpórea: incidência, fatores de risco e mortalidade

“…Acute renal failure requiring dialysis (acute renal failure-D) after cardiac surgery, occurs from 0.5% to 15.0% [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]23,26 . Its occurrence in our study was 4.9% (11 cases), greater than that reported in other studies, apart from that of Suen et al 15 and of OR -odds ratio; CI -confidence interval; ECC -extracorporeal circulation.…”

“…Mortality related to acute renal failure-D reported in the literature varies from 23.9% to 88.9% [6][7][8][9][10][11][14][15][16]18,19 , and in the last 10 years, these values have varied from 23.9% to 63.7% 8,11,15,16,18,19 . The mortality rate observed in patients without acute renal failure was 1.6%, compared with 25.0% for those with it.…”

“…In 18.0% to 47.0% of cases, it is related to a surgical event, and acute tubular necrosis is the main type of lesion 1,2,4 . The great variation in the incidence of acute renal failure among the studies presents a multifactor profile, including different diagnostic criteria, such as the study design, inclusion and exclusion criteria, profile of the patients and of the centers involved in the sample, hindering study comparisons 5 .In cardiac surgery, its incidence ranges from 3.5% to 31.0% [5][6][7][8][9][10][11][12] , and the need for dialysis occurs in 0.3% to 15.0% of cases [5][6][7][8][9][10][11][12][13][14][15][16][17][18] . The presence of acute renal failure in these patients increases the mortality rate from 0.4% to 4.4% to 1.3% to 22.3%, and when dialysis is required, these rates reach 25.0% to 88.9% [5][6][7][8][9][10][11][12][13][14][15][16][17][18] , making it an independent risk factor for mortality, according to Chertow et al 16 , and increasing 8-fold the death odds ratio among these patients.…”
