“…However, in addition to those factors, we demonstrated that polypharmacy significantly raised the odds of having CKD. Polypharmacy has been shown to be associated with an increased risk for acute kidney injury [18] , but only few, small studies have addressed the role of polypharmacy in CKD [19] . Polypharmacy, defined as the use of ≥ 5 drugs, is particularly common in the elderly [22,38] .…”

“…Furthermore, we aimed to assess the awareness of CKD in our cohort and to identify possible risk factors, with particular interest in polypharmacy. While polypharmacy is an established risk factor for acute kidney injury in elderly patients [18] , only few studies have studied the relationship between polypharmacy and the incidence and prevalence of CKD [19] .…”

Background: In aging populations with an ever-growing burden of risk factors such as obesity, diabetes, and hypertension, chronic kidney disease (CKD) is on the rise. However, little is known about its exact prevalence among elderly adults, and often albuminuria is not included in the definition of CKD. Moreover, novel equations for the estimated glomerular filtration rate (eGFR) have recently emerged, which have not been applied comprehensively to older adults. Data on CKD awareness among the elderly are sparse. Objectives: To determine the prevalence of CKD among older adults by eGFR and albumin/creatinine ratio (ACR), compare the performance of 6 established and novel eGFR formulas, explore risk factors, and determine the awareness of CKD in a large cohort of community-dwelling elderly from Germany. Methods: A total of 1,628 subjects from the Berlin Aging Study II (BASE-II) were included in this analysis (mean age 68.7 years; 51.2% female). Extensive cross-sectional data on sociodemographics, lifestyle, medication, and diagnoses were inquired during structured interviews and a medical examination, and blood and urine parameters were measured. Results: In all, 77.1% of the subjects had hypertension, 12.4% had diabetes, and 18.3% were obese. The prevalence of CKD strongly depended on the eGFR equations used: 25.4% (full age spectrum [FAS] equation), 24.6% (Berlin Initiative Study), 23.1% (Lund-Malmö revised), 19.3% (Cockcroft-Gault), 16.4% (Chronic Kidney Disease-Epidemiology Collaboration [CKD-EPI]), and 14.7% (Modification of Diet in Renal Disease [MDRD]). Of the subjects with an eGFR_FAS <60 mL/min/1.73 m² and/or an ACR >30 mg/g, only 3.9% were aware of having CKD. Polypharmacy, age, BMI, coronary artery disease, non-HDL cholesterol, and female sex were independently associated with CKD. Conclusions: CKD is prevalent among older adults in Germany, but awareness is low. The FAS equation detects higher rates of CKD than MDRD and CKD-EPI, which are most widely used at present. Also, when CKD is defined based on eGFR and albuminuria, considerably more people are identified than by eGFR alone. Finally, polypharmacy is associated with an increased risk for CKD in the elderly.

and mortality. 4,9 Hemodynamic disturbance during OPCAB has been reported to have a biventricular contribution, and the major cause is believed to be diastolic dysfunction and abnormal filling of both ventricles. 10,11 As such, it is possible that an underlying increased LVFP may aggravate the intraoperative hemodynamic disturbance, resulting in a higher rate of postoperative AKI. Although previous studies have reported the effect of diastolic dysfunction on postoperative outcomes, including death or major adverse cardiac events (MACE), 4,12 postoperative renal dysfunction was evaluated only as a secondary outcome and the association between increased LVFP in patients with normal LV systolic function and postoperative AKI has not been fully evaluated.The ratio of the early transmitral blood flow velocity to early diastolic velocity of the mitral annulus (E/e′) has been reported to have good predictive power for mean LV diastolic pressure or mean LVFP and has been used to estimate the diastolic function of the heart. 13,14 E/e′ >15 is P erioperative acute kidney injury (AKI) has been reported to be an important contributor to postoperative morbidity and mortality especially after cardiovascular surgery, including coronary artery bypass graft (CABG). 1,2 Off-pump coronary artery bypass surgery (OPCAB) has been associated with less severe and a lower incidence of AKI compared with on-pump CABG. 3 Nonetheless, there is still a substantial incidence of AKI after OPCAB and it is caused by transient circulatory arrest, global hypoperfusion, myocardial ischemia-reperfusion injury, and inflammatory response. 3 The incidence of diastolic dysfunction in patients who undergo CABG has been reported as high. 4,5 Although many studies have reported systolic dysfunction of the heart as a risk factor for postoperative AKI, 6,7 the association between preoperative diastolic dysfunction and postoperative AKI has not been investigated. A stiff left ventricle with low compliance would lead to an elevated LV filling pressure (LVFP), 8 which is associated with higher morbidity Background: The ratio of the early transmitral flow velocity to early diastolic velocity of the mitral annulus (E/e′) is an echocardiographic index of mean left ventricular (LV) filling pressure. We investigated the association between the preoperative E/e′ ratio and postoperative acute kidney injury (AKI) during off-pump coronary artery bypass surgery (OPCAB).
