T1 - Chronic hyperglycemia is associated with acute kidney injury in patients undergoing CABG surgery – a cohort study JF - BMC Cardiovascular Disorders N2 - Background Chronic hyperglycemia (CHG) with HbA1c as an indicator affects postoperative mortality and morbidity after coronary artery bypass grafting surgery (CABG). Acute kidney injury (AKI) is one of the frequent postoperative complications after CABG impacting short-and long-term outcomes. We investigated the association between CHG and postoperative incidence of AKI in CABG patients with and without history of diabetes mellitus (DM). Methods This cohort study consecutively enrolled patients undergoing CABG in 2009 at the department for cardiovascular surgery. CHG was defined as HbA1c ≥ 6.0 %. Patients with advanced chronic kidney disease (CKD) were excluded. The incidence of postoperative AKI and its association with CHG was analyzed by univariate and multivariate logistic regression modeling. Results Three-hundred-seven patients were analyzed. The incidence of AKI was 48.2 %. Patients with CHG (n = 165) were more likely to be female and had greater waist circumference as well as other comorbid conditions, such as smoking, history of DM, CKD, hypertension, pulmonary hypertension, and chronic obstructive pulmonary disease (all p ≤ 0.05). Preoperative eGFR, atrial fibrillation (AF), history of DM and CHG were associated with an increased risk of postoperative AKI in univariate analyses. In multivariate modelling, history of DM as well as preoperative eGFR and AF lost significance, while age, CHG and prolonged OP duration (p < 0.05) were independently associated with postoperative AKI. Conclusions Our results suggest that CHG defined on a single measurement of HbA1c ≥ 6.0 % was associated with the incidence of AKI after CABG. This finding might implicate that treatment decisions, including the selection of operative strategies, could be based on HbA1c measurement rather than on a recorded history of diabetes. Y1 - 2015 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:bvb:20-opus-125224 VL - 15 IS - 41 ER - TY - THES A1 - Wagner, Martin T1 - Chronic Kidney Disease as an Important Co-morbid Condition in Coronary Heart Disease Patients T1 - Chronische Nierenerkrankung als bedeutender Risikofaktor bei Patienten mit koronarer Herzkrankheit N2 - In patients with coronary heart disease (CHD) the control of the modifiable “traditional” cardiovascular risk factors such as hypertension, dyslipidemia, diabetes, achieving/maintaining normal body weight and smoking cessation is of major importance to improve prognosis. Guideline recommendations for secondary CHD prevention include specific treatment targets for blood pressure, lipid levels, and markers of glucose metabolism for both younger and older patients. Chronic kidney disease (CKD) has been identified as a “non-traditional” risk factor for worse outcome in CHD patients, as it is associated with a markedly increased risk for subsequent CV events and mortality. The specific objectives of the current thesis-project are to investigate (a) the quality of care in a recent sample of German CHD patients and to investigate variation of risk factor control between younger and elder patients (≤70 versus >70 years), (b) to analyze the prevalence of CKD across Europe in stable CHD patients in the outpatient setting and during a hospital stay for CHD, (c) to investigate the level of awareness of CKD in German CHD patients and their treating physicians. Data from the European-wide EUROASPIRE IV study were used that include data on 7998 CHD patients in the ambulatory setting (study visit) and during a hospital stay for CHD (index). The German EUROASPIRE IV study center in Würzburg recruited 536 patients in 2012-2013. Risk factor control was compared against the current recommendations of the European Society of Cardiology. CKD was described by stages of glomerular filtration rate (eGFR) and albuminuria. German patients were asked in an additional kidney specific module whether they have ever been told by a physician about renal impairment. The fact that CKD or acute kidney injury (AKI) was mentioned in prominent parts of the hospital discharge letter as well as correct ICD-coding of CKD or AKI served as a proxy for physician’s awareness of CKD. The majority of German CHD patients was treated with the recommended drug therapies including e.g. β-blockers, anti-platelets and statins. However, treatment targets for blood pressure and LDL-cholesterol levels were not achieved in many patients (45% and 53%, respectively) and glycemic control in diabetic CHD patients with HbA1-levels <7% was insufficient (61%). A minority of patients reported on current smoking (10%), but unhealthy life-styles e.g. overweight/obesity (85%/37%) were frequent. Patterns of care differed between younger and older CHD patients while older patients were less likely to receive the recommended medical CHD-therapy, were more likely to have uncontrolled blood pressure and also to be diabetic. However, a greater proportion of diabetic patients >70 years was achieving the HbA1c target, and less elder patients were current smokers or were obese. About 17% of patients on average had CKD (eGFR< 60 ml/min/1.73m²) in the entire European sample at the study visit, and an additional 10% had albuminuria despite preserved eGFR, with considerable variation among countries. Impaired kidney function was observed in every fifth patient admitted for CHD in the entire European dataset of the EUROASPIRE IV study. Of the German CHD patients with CKD at the study visit, only a third were aware of their renal impairment. A minority of these patients was being seen by nephrologists, however, with a higher likelihood of CKD awareness and specialist care in more advanced stages of CKD. About a third of patients admitted for CHD showed either CKD or AKI during the hospital stay, but the discharge letter mentioned chronic or acute kidney disease only in every fifth of these patients. In contrast, correct ICD coding of CKD or AKI was more complete, but still suboptimal. In summary, quality of secondary prevention in German CHD patients indicates considerably room for improvement, with life-style modifications may become an even greater factor in prevention campaigns than medical treatment into certain target ranges. Preventive therapies should also consider different needs in older individuals acknowledging physical and mental potential, other comorbidities and drug-interactions with co-medication. CKD is common in CHD patients, not only in the elderly. Since CHD and CKD affect each other and impact on worse prognosis of each other, raising the awareness of CKD among patients and physicians and considering CKD in medical therapy may improve prognosis and slow disease progression of CHD as well as CKD. N2 - Bei Patienten mit koronarer Herzkrankheit (KHK) ist die Behandlung der „klassischen“ kardiovaskulären Risikofaktoren wie Bluthochdruck, Hypercholesterinämie, Diabetes, ein normales Körpergewicht sowie der Nikotinverzicht von Bedeutung, um die Prognose zu verbessern. Leitlinien empfehlen in der Sekundärprävention spezifische Behandlungsziele für Bluthochdruck, Hypercholesterinämie und Diabetes. Die chronische Niereninsuffizienz (NI) stellt einen „nicht-klassischen“ Risikofaktor für eine schlechtere Prognose bei KHK-Patienten dar und ist assoziiert mit einem erhöhten Risiko für eine Progression der KHK und kardiovaskuläre Mortalität. Die Studienziele der vorgelegten Arbeit beinhalten (a) die Umsetzung der KHK-Leitlinien in einem deutschen Kollektiv von Patienten inklusive der Unterschiede in der Versorgung zwischen Jüngeren und älteren Patienten (≤70 / >70 Jahre). Zudem (b) wird die Prävalenz der NI in stabilen ambulanten Verhältnissen und ebenso während eines Krankenhausaufenthaltes aufgrund eines KHK-Ereignisses in 24 Europäischen Ländern inklusive Deutschland untersucht. Schließlich (c) wird am deutschen Studienzentrum das Bewusstsein („Awareness“) für Nierenerkrankungen sowohl bei den Patienten als auch den behandelnden Ärzten analysiert. Es wurden die Daten der europaweiten EUROASPIRE IV Studie verwendet, für die zwischen 2012 und 2013 insgesamt 7998 KHK Patienten rekrutiert wurden. Sie enthält Informationen aus einem ambulanten Studienbesuch und aus einem Krankenhausaufenthalt aufgrund eines KHK-Ereignisses (Index). Am deutschen Studienzentrum in Würzburg wurden 536 Patienten eingeschlossen und die Qualität der Risikofaktorkontrolle nach den Empfehlungen der Europäischen Gesellschaft für Kardiologie untersucht. Chronische NI wurde in Stadien eingeteilt anhand von glomerulärer Filtrationsrate (eGFR) und Albuminurie. Zudem Am deutschen EUROASPIRE IV Studienzentrum wurden die Patienten zudem in einem zusätzlichen „Nieren-spezifischen Modul“ befragt, ob sie jemals von einem Arzt hinsichtlich einer Nierenerkrankung aufgeklärt wurden. Um das Bewusstsein für Nierenerkrankungen bei Ärzten einzuschätzen, wurde untersucht, ob akute oder chronische Nierenfunktionseinschränkungen im Arztbrief des Index-Aufenthaltes erwähnt wurden, und ob Nierenerkrankungen adäquat ICD-codiert waren. Die Mehrheit der deutschen KHK-Patienten wurde mit den empfohlenen Präparaten β-Blocker, Aspirin und Statinen behandelt, allerdings wurden die Ziel-/Grenzwerte für Blutdruck und Cholesterin oftmals nicht erreicht (45% bzw. 53%), ebenso wie die Blutzuckerkontrolle bei diabetischen Patienten (39%). Nur wenige Patienten waren aktive Raucher (10%), aber viele waren übergewichtig (85%) oder adipös (37%). Ältere Patienten erhielten seltener die empfohlenen Präparate und waren häufiger hypertensiv oder Diabetiker. Allerdings zeigten sich diabetische Patienten >70 Jahre besser kontrolliert und ältere Patienten waren seltener Raucher oder übergewichtig. Im Durchschnitt hatten 17% der KHK Patienten – mit großer Variation innerhalb der teilnehmenden Staaten – im EUROASPIRE IV Gesamtkollektiv eine chronische NI (eGFR <60 ml/min/1.73m²) und zusätzliche 10% hatten Albuminurie bei erhaltener eGFR. Eine eingeschränkte Nierenfunktion zeigte sich auch in jedem fünften Patienten bei Krankenhausaufnahme für das Index Ereignis im EUROASPIRE IV Gesamtkollektiv. Von den deutschen Patienten mit chronischer NI gab nur ein Drittel an, von ihrer Nierenfunktionseinschränkung zu wissen. Nur wenige dieser Patienten wurden von einem Nephrologen behandelt, wobei Patienten mit fortgeschrittener NI sich sowohl häufiger ihrer NI bewusst waren als auch von Spezialisten behandelt wurden. Im Index-Krankenhausaufenthalt hatte ein Drittel der Patienten wenigstens einen Hinweis auf eine entweder chronisch oder akut eingeschränkte Nierenfunktion. Lediglich in einem Fünftel war diese Diagnose im Entlassungsbrief erwähnt, während die Codierung nach Entlassung zwar vollständiger, aber immer noch lückenhaft war. Die Qualität der Sekundärprävention in deutschen KHK-Patienten lässt weiterhin beträchtlichen Raum für Verbesserung. Hierbei erscheinen die Veränderung im Lebensstil weitaus zielführender zu sein als die medikamentöse Therapie in definierte Zielbereiche. Die medizinische Therapie und die Herangehensweise an Verhaltensänderungen muss insbesondere bei älteren Patienten an die besondere Bedürfnisse dieser Patientengruppe angepasst werden. Chronische NI ist häufig bei KHK Patienten anzutreffen, nicht nur bei älteren Studienteilnehmern. KHK und chronische NI beeinflussen sich und die Prognose des jeweils anderen gegenseitig, sodass eine Steigerung des Bewusstseins für Nierenerkrankungen sowohl bei Patienten als auch bei Ärzten, und die Anpassung der Behandlungsstrategie womöglich zu einer Verbesserung der Prognose und zur Verlangsamung des Fortschreitens beider Erkrankungen, KHK und NI führen.

T1 - Control of cardiovascular risk factors and its determinants in the general population – findings from the STAAB cohort study JF - BMC Cardiovascular Disorders N2 - Background: While data from primary care suggest an insufficient control of vascular risk factors, little is known about vascular risk factor control in the general population. We therefore aimed to investigate the adoption of adequate risk factor control and its determinants in the general population free of cardiovascular disease (CVD). Methods: Data from the Characteristics and Course of Heart Failure Stages A-B and Determinants of Progression (STAAB) Cohort Study, a population-based study of inhabitants aged 30 to 79 years from the general population of Würzburg (Germany), were used. Proportions of participants without established CVD meeting targets for risk factor control recommended by 2016 ESC guideline were identified. Determinants of the accumulation of insufficiently controlled vascular risk factors (three or more) were assessed. Results: Between December 2013 and April 2015, 1379 participants without CVD were included; mean age was 53.1 ± 11.9 years and 52.9% were female; 30.8% were physically inactive, 55.2% overweight, 19.3% current smokers. Hypertension, dyslipidemia, and diabetes mellitus were prevalent in 31.8%, 57.6%, and 3.9%, respectively. Treatment goals were not reached despite medication in 52.7% of hypertensive, in 37.3% of hyperlipidemic and in 44.0% of diabetic subjects. Insufficiently controlled risk was associated with male sex (OR 1.94, 95%CI 1.44–2.61), higher age (OR for 30–39 years vs. 70–79 years 4.01, 95%CI 1.94–8.31) and lower level of education (OR for primary vs. tertiary 2.15, 95%CI 1.48–3.11). Conclusions: In the general population, prevalence of vascular risk factors was high. We found insufficient identification and control of vascular risk factors and a considerable potential to improve adherence to cardiovascular guidelines for primary prevention. Further studies are needed to identify and overcome patient- and physician-related barriers impeding successful control of vascular risk factors in the general population.

Patient's anxiety is therefore a significant issue, which often lead to avoidance of participation of relevant examinations as CRC-screening. Non-pharmacological anxiety management interventions such as music might contribute to relaxation in the phase prior and during endoscopy. Although music's anxiolytic effects have been reported previously, no objective measurement of stress level reduction has been reported yet. Focus of this study was to evaluate the objective measurement of the state of relaxation in patients undergoing colonoscopy. Methods: Prospective study (n = 196) performed at one endoscopic high-volume center. Standard colonoscopy was performed in control group. Interventional group received additionally self-chosen music over earphones. Facial Electromyography (fEMG) activity was obtained. Clinician Satisfaction with Sedation Instrument (CSSI) and Patients Satisfaction with Sedation Instrument (PSSI) was answered by colonoscopists and patients, respectively. Overall satisfaction with music accompanied colonoscopy was obtained if applicable. Results: Mean difference measured by fEMG via musculus zygomaticus major indicated a significantly lower stress level in the music group [7.700(±5.560) μV vs. 4.820(±3.330) μV; p = 0.001]. Clinician satisfaction was significantly higher with patients listening to music [82.69(±15.04) vs. 87.3(±15.02) pts.; p = 0.001]. Patient's satisfaction was higher but did not differ significantly. Conclusions: We conclude that self-chosen music contributes objectively to a reduced stress level for patients and therefore subjectively perceived satisfaction for endoscopists. Therefore, music should be considered as a non-pharmacological treatment method of distress reduction especially in the beginning of endoscopic procedures.

A1 - Heuschmann, Peter U. A1 - Störk, Stefan T1 - Functional versus morphological assessment of vascular age in patients with coronary heart disease JF - Scientific Reports N2 - Communicating cardiovascular risk based on individual vascular age (VA) is a well acknowledged concept in patient education and disease prevention. VA may be derived functionally, e.g. by measurement of pulse wave velocity (PWV), or morphologically, e.g. by assessment of carotid intima-media thickness (cIMT). The purpose of this study was to investigate whether both approaches produce similar results. Within the context of the German subset of the EUROASPIRE IV survey, 501 patients with coronary heart disease underwent (a) oscillometric PWV measurement at the aortic, carotid-femoral and brachial-ankle site (PWVao, PWVcf, PWVba) and derivation of the aortic augmentation index (AIao); (b) bilateral cIMT assessment by high-resolution ultrasound at three sites (common, bulb, internal). Respective VA was calculated using published equations. According to VA derived from PWV, most patients exhibited values below chronological age indicating a counterintuitive healthier-than-anticipated vascular status: for VA(PWVao) in 68% of patients; for VA\(_{AIao}\) in 52% of patients. By contrast, VA derived from cIMT delivered opposite results: e.g. according to VA\(_{total-cIMT}\) accelerated vascular aging in 75% of patients. To strengthen the concept of VA, further efforts are needed to better standardise the current approaches to estimate VA and, thereby, to improve comparability and clinical utility.

Our aim was to investigate prevalence and characteristics of HF in patients with coronary heart disease (CHD), and to assess the adherence to current HF guidelines in patients with HF stage C, thus identifying potential targets for the optimization of guideline implementation. Methods: Patients from the German sample of the European Action on Secondary and Primary Prevention by Intervention to Reduce Events (EuroAspire) IV survey with a hospitalization for CHD within the previous six to 36 months providing valid data on echocardiography as well as on signs and symptoms of HF were categorized into stages of HF: A, prevalence of risk factors for developing HF; B, asymptomatic but with structural heart disease; C, symptomatic HF. A Guideline Adherence Indicator (GAI-3) was calculated for patients with reduced (≤40%) left ventricular ejection fraction (HFrEF) as number of drugs taken per number of drugs indicated; beta-blockers, angiotensin converting enzyme inhibitors/angiotensin receptor blockers, and mineralocorticoid receptor antagonists (MRA) were considered. Results: 509/536 patients entered analysis. HF stage A was prevalent in n = 20 (3.9%), stage B in n = 264 (51.9%), and stage C in n = 225 (44.2%) patients; 94/225 patients were diagnosed with HFrEF (42%). Stage C patients were older, had a longer duration of CHD, and a higher prevalence of arterial hypertension. Awareness of pre-diagnosed HF was low (19%). Overall GAI-3 of HFrEF patients was 96.4% with a trend towards lower GAI-3 in patients with lower LVEF due to less thorough MRA prescription. Conclusions: In our sample of CHD patients, prevalence of HF stage C was high and a sizable subgroup suffered from HFrEF. Overall, pharmacotherapy was fairly well implemented in HFrEF patients, although somewhat worse in patients with more reduced ejection fraction. Two major targets were identified possibly suited to further improve the implementation of HF guidelines: 1) increase patients´ awareness of diagnosis and importance of HF; and 2) disseminate knowledge about the importance of appropriately implementing the use of mineralocorticoid receptor antagonists. Trial registration: This is a cross-sectional analysis of a non-interventional study. Therefore, it was not registered as an interventional trial.

It may be explained by reduced erythropoietin (EPO) synthesis, but recent data suggest that EPO-resistance and diminished iron availability due to inflammation contribute significantly. In this cohort study, we evaluated the impact of hepcidin-25—the key hormone of iron-metabolism—on clinical outcomes in diabetic patients with CKD along with endogenous EPO levels. Methods 249 diabetic patients with CKD of any stage, excluding end-stage renal disease (ESRD), were enrolled (2003–2005), if they were not on EPO-stimulating agent and iron therapy. Hepcidin-25 levels were measured by radioimmunoassay. The association of hepcidin-25 at baseline with clinical variables was investigated using linear regression models. All-cause mortality and a composite endpoint of CKD progression (ESRD or doubling of serum creatinine) were analyzed by Cox proportional hazards models. Results Patients (age 67 yrs, 53% male, GFR 51 ml/min, hemoglobin 131 g/L, EPO 13.5 U/L, hepcidin-25 62.0 ng/ml) were followed for a median time of 4.2 yrs. Forty-nine patients died (19.7%) and forty (16.1%) patients reached the composite endpoint. Elevated hepcidin levels were independently associated with higher ferritin-levels, lower EPO-levels and impaired kidney function (all p<0.05). Hepcidin was related to mortality, along with its interaction with EPO, older age, greater proteinuria and elevated CRP (all p<0.05). Hepcidin was also predictive for progression of CKD, aside from baseline GFR, proteinuria, low albumin- and hemoglobin-levels and a history of CVD (all p<0.05). Conclusions We found hepcidin-25 to be associated with EPO and impaired kidney function in diabetic CKD. Elevated hepcidin-25 and EPO-levels were independent predictors of mortality, while hepcidin-25 was also predictive for progression of CKD. Both hepcidin-25 and EPO may represent important prognostic factors of clinical outcome and have the potential to further define “high risk” populations in CKD.

Heme oxygenase-1 (HO-1) is an enzyme synthesized in renal tubular cells as one of the most intense responses to oxidant stress linked with protective, anti-inflammatory properties. Yet, it is unknown if serum HO-1 induction following cardiac surgical procedure involving cardiopulmonary bypass (CPB) is associated with incidence and severity of AKI. Patients and methods: In the present study, we used data from a prospective cohort study of 150 adult cardiac surgical patients. HO-1 measurements were performed before, immediately after and 24 hours post-CPB. In univariate and multivariate analyses, the association between HO-1 and AKI was investigated. Results: AKI with an incidence of 23.3% (35 patients) was not associated with an early elevation of HO-1 after CPB in all patients (P=0.88), whereas patients suffering from AKI developed a second burst of HO-1 24 hours after CBP. In patients without AKI, the HO-1 concentrations dropped to baseline values (P=0.031). Furthermore, early HO-1 induction was associated with CPB time (P=0.046), while the ones 24 hours later lost this association (P=0.219). Conclusion: The association of the second HO-1 burst 24 hours after CBP might help to distinguish between the causality of AKI in patients undergoing CBP, thus helping to adapt patient stratification and management.

A1 - Störk, Stefan T1 - Impact of cardiovascular risk factors on myocardial work-insights from the STAAB cohort study JF - Journal of Human Hypertension N2 - Myocardial work is a new echocardiography-based diagnostic tool, which allows to quantify left ventricular performance based on pressure-strain loops, and has been validated against invasively derived pressure-volume measurements. Myocardial work is described by its components (global constructive work [GCW], global wasted work [GWW]) and indices (global work index [GWI], global work efficiency [GWE]). Applying this innovative concept, we characterized the prevalence and severity of subclinical left ventricular compromise in the general population and estimated its association with cardiovascular (CV) risk factors. Within the Characteristics and Course of Heart Failure STAges A/B and Determinants of Progression (STAAB) cohort study we comprehensively phenotyped a representative sample of the population of Würzburg, Germany, aged 30-79 years. Indices of myocardial work were determined in 1929 individuals (49.3% female, mean age 54 ± 12 years). In multivariable analysis, hypertension was associated with a mild increase in GCW, but a profound increase in GWW, resulting in higher GWI and lower GWE. All other CV risk factors were associated with lower GCW and GWI, but not with GWW. The association of hypertension and obesity with GWI was stronger in women. We conclude that traditional CV risk factors impact selectively and gender-specifically on left ventricular myocardial performance, independent of systolic blood pressure. Quantifying active systolic and diastolic compromise by derivation of myocardial work advances our understanding of pathophysiological processes in health and cardiac disease.
