Background: The aim of this study was to determine the influence of preoperative kidney dysfunction (ie, chronic kidney disease (CKD)) on postoperative cardiovascular events, infection, acute kidney injury and hospital mortality in patients undergoing coronary artery bypass grafting (CABG).Methods and Results: A multi-institutional retrospective study was performed at 14 hospitals of adult patients undergoing isolated CABG from 2007 to 2008 (n=1,522). We classified CKD level according to preoperative estimated glomerular filtration rate (eGFR): normal, eGFR >90 ml•min–1•1.73 m–2; mild, eGFR 60–90 ml•min–1•1.73 m–2; moderate, eGFR 30–59 ml•min–1•1.73 m–2; and severe, eGFR <30 ml•min–1•1.73 m–2, and assessed postoperative outcome. Preoperative CKD distribution was as follows: normal, n=121 (8%); mild, n=713 (47%); moderate, n=515 (34%); and severe, n=169 (11%). Risk of infection was strongly correlated with CKD level (normal, 3.3%; mild, 7.0%; moderate, 8.3%; severe, 17.0%; P<0.01). The risk of in-hospital death was also strongly correlated with CKD level (normal, 1.7%; mild, 1.0%; moderate, 1.6%; severe, 5.9%; P<0.01). On multivariate logistic regression analysis, CKD level was identified as a significant risk factor for postoperative infection, acute kidney injury, and in-hospital death.Conclusions: Advanced preoperative CKD is a strong predictor of postoperative infection, acute kidney injury and in-hospital death after CABG. © 2014 THE JAPANESE CIRCULATION SOCIETY.

Background: Few large-scale studies have examined the relationship between bleeding events not related to coronary artery bypass grafting (CABG), and the vascular access route used in acute coronary syndrome (ACS) or in elective treatment of coronary artery disease (CAD). Methods and Results: We compared the incidence of bleeding events occurring up to 3 days after percutaneous coronary intervention (PCI) or loading dose of prasugrel or clopidogrel in 2 studies of Japanese patients (PRASFITACS, femoral and radial routes, n=683 and 531; PRASFIT-Elective, femoral and radial routes, n=135 and 508). Rates of periprocedural bleeding, bleeding not related to CABG, and puncture site bleeding were consistently lower in the radial access route group than in the femoral access route group in both studies. Risk factors for periprocedural bleeding included sex, body weight, age, and access route in PRASFIT-ACS (femoral access: hazard ratio [HR], 3.739; 95% confidence interval [CI]: 1.727-8.094; radial access: HR, 0.288; 95% CI: 0.128-0.65), and body weight, age, and access route in PRASFIT-Elective (femoral access: HR, 12.32; 95% CI 1.282->100; radial access: HR, 0.125; 95% CI: 0.013-1.205). Conclusions: The incidence of periprocedural bleeding is lower with a radial access route than with a femoral access route for PCI in Japanese patients with ACS or those undergoing elective PCI for CAD. © 2015, Japanese Circulation Society.

Background and Objectives: Little information is available regarding adult patients with congenital heart disease (CHD) who needed unscheduled hospitalization (USH). This paper aims to elucidate the clinical features of adult patients with CHD requiring USH. Subjects and Methods: Study subjects included patients with CHD aged 18 years or older who were hospitalized at our facility during a 5-year study period. Medical records were retrospectively reviewed and data regarding USH were collected. Patient's background, underlying heart disease, cause of hospitalization, and prognosis (second USH regardless of cause or death) were examined. Results: Overall, 959 CHD patients underwent a total of 1761 hospitalizations, including 145 patients who were unexpectedly hospitalized 239 times. The median age at USH was 27 years old. Of the 959 patients, 54% were male. Underlying heart diseases included repaired tetralogy of Fallot (21%), single ventricular physiology after Fontan operation (17%), and Eisenmenger syndrome (12%). The causes of USH included arrhythmia (40%), heart failure (20%), infectious disease (13%), and hemorrhage or thrombus (13%). A total of 48 patients required readmission. In total, 13 patients died, including four hospital deaths. The USH-free survival rate was 77% for 1 year and 58% for 3 years. Conclusion: The rate of USH was high for adults with complicated CHD. Common causes of USH included arrhythmia, heart failure, hemorrhage-related or thrombus-related conditions and infection. These data provide the current status of medical care for adult CHD patients in Japan and their therapeutic needs. Source
