    ABSTRACT: Cystatin C (CysC) is a protease encoded by housekeeping genes. Although its prognostic value in heart failure (HF) is well known, it is debatable whether this value is due to the greater accuracy of CysC in calculating the glomerular filtration rate or to its involvement in pathological ventricular remodeling. The aim of this study was to determine whether CysC expression changes in the myocardium of fetuses of different ages and in the myocardium of adults with various cardiovascular diseases, as well as to analyze the correlation between its serum concentrations and cardiac structure and morphology in a patient group with HF.

    ABSTRACT: Background: Our aims were to assess the effectiveness of a diabetes (DM) management protocol to increase scheduled insulin therapy and to improve glycemic inpatient control. Patients and methods: We designed an analytical retrospective cohort study comparing 2 groups of medical services hospitalized patients with a primary of secondary discharge diagnosis of DM, before (group PRE) and after (group POS) the delivery of a DM management protocol. We analyzed the quality of attention by process indicators (cumulative probability of receive scheduled insulin therapy, evaluated with Kaplan-Meier analysis) and result indicators (adjusted glucose differences (group POS - group PRE), evaluated with multivariate regression models). Results: A number of patients (355) were included (228 group PRE and 127 group POS). The median time to scheduled insulin regimen beginning was 1 (CI 95%: 0-2.5) day in group POS and 4 (CI 95%: 2-6) days in group PRE (p=0.056). First 48 hours mean glucose in patients without scheduled insulin therapy was lower in group POS than in group PRE (163.9 versus 186.7 mg/dl; p=0.025). The first 24 hours mean glucose was significantly lower in patients of group POS, with a difference between both groups of -24.8 mg/dl (CI 95%: -40.5-(-9); p=0.002). Stratified analysis showed statistically significant mean in-hospital glucose difference only in the nothing by mouth situation (-29.8 mg/dl; CI 95%: -58.9-(-0.6); p=0.045). Conclusion: The delivery of an institutional protocol can improve hospitalized DM patients management quality.

    ABSTRACT: La cistatina C (CisC) es una proteasa codificada por genes de mantenimiento («housekeeping genes»). Aunque su valor pronóstico en la insuficiencia cardiaca (IC) es bien conocido, se debate si es debido a su mayor precisión en la estimación del filtrado glomerular, o a su implicación en el remodelado ventricular patológico. El propósito de este estudio fue comprobar si la expresión de CisC se modificaba en el miocardio de fetos de diferentes edades y en el de adultos con diversas enfermedades cardiovasculares, así como analizar la correlación entre sus concentraciones séricas y la estructura y morfología cardiaca en un grupo de pacientes con IC.

    ABSTRACT: The objective was to assess the prognostic importance of various glycaemic control measures on hospital mortality. Retrospective, analytical cohort study that included patients hospitalised in internal medicine departments with a diagnosis related to diabetes mellitus (DM), excluding acute decompensations. The clinical endpoint was hospital mortality. We recorded clinical, analytical and glycaemic control-related variables (scheduled insulin administration, plasma glycaemia at admission, HbA1c, mean glycaemia (MG) and in-hospital glycaemic variability and hypoglycaemia). The measurement of hospital mortality predictors was performed using univariate and multivariate logistic regression. A total of 384 patients (50.3% men) were included. The mean age was 78.5 (SD, 10.3) years. The DM-related diagnoses were type 2 diabetes (83.6%) and stress hyperglycaemia (6.8%). Thirty-one (8.1%) patients died while in hospital. In the multivariate analysis, the best model for predicting mortality (R(2)=0.326; P<.0001) consisted, in order of importance, of age (χ(2)=8.19; OR=1.094; 95% CI 1.020-1.174; P=.004), Charlson index (χ(2)=7.28; OR=1.48; 95% CI 1.11-1.99; P=.007), initial glycaemia (χ(2)=6.05; OR=1.007; 95% CI 1.001-1.014; P=.014), HbA1c (χ(2)=5.76; OR=0.59; 95% CI 0.33-1; P=.016), glycaemic variability (χ(2)=4.41; OR=1.031; 95% CI 1-1.062; P=.036), need for corticosteroid treatment (χ(2)=4.03; OR=3.1; 95% CI 1-9.64; P=.045), administration of scheduled insulin (χ(2)=3.98; OR=0.26; 95% CI 0.066-1; P=.046) and systolic blood pressure (χ(2)=2.92; OR=0.985; 95% CI 0.97-1.003; P=.088). An increase in initial glycaemia and in-hospital glycaemic variability predict the risk of mortality for hospitalised patients with DM.

    ABSTRACT: This study was intended to assess the effectiveness and predictors factors of inpatient blood glucose control in diabetic patients admitted to medical departments. A retrospective, analytical cohort study was conducted on patients discharged from internal medicine with a diagnosis related to diabetes. Variables collected included demographic characteristics, clinical data and laboratory parameters related to blood glucose control (HbA1c, basal plasma glucose, point-of-care capillary glucose). The cumulative probability of receiving scheduled insulin regimens was evaluated using Kaplan-Meier analysis. Multivariate regression models were used to select predictors of mean inpatient glucose (MHG) and glucose variability (standard deviation [GV]). The study sample consisted of 228 patients (mean age 78.4 (SD 10.1) years, 51% women). Of these, 96 patients (42.1%) were treated with sliding-scale regular insulin only. Median time to start of scheduled insulin therapy was 4 (95% CI, 2-6) days. Blood glucose control measures were: MIG 181.4 (SD 41.7) mg/dL, GV 56.3 (SD 22.6). The best model to predict MIG (R(2): .376; P<.0001) included HbA1c (b=4.96; P=.011), baseline plasma glucose (b=.056; P=.084), mean capillary blood glucose in the first 24hours (b=.154; P<.0001), home treatment (versus oral agents) with basal insulin only (b=13.1; P=.016) or more complex (pre-mixed insulin or basal-bolus) regimens (b=19.1; P=.004), corticoid therapy (b=14.9; P=.002), and fasting on admission (b=10.4; P=.098). Predictors of inpatient blood glucose control which should be considered in the design of DM management protocols include home treatment, HbA1c, basal plasma glucose, mean blood glucose in the first 24hours, fasting, and corticoid therapy.

    ABSTRACT: To analyse the information collected in hospital discharge reports (HDR) that are given to patients with a diagnosis of heart failure (HF), and demonstrate the improvement in the content of these reports after the introduction of an intervention. HDR with HF as the main diagnosis issued by the Department of Internal Medicine were analysed, and the presence of the diagnosis, prognosis and therapeutic data in these HDR was compared in a sample before and after the intervention, which consisted of reporting the results of analysis of the initial sample to the physicians. A total of 651 HDR (371 pre-intervention and 280 post-intervention) were analysed. Most of the HDR (over 70%) did not include the functional class. Most of the HDR did not include information about echocardiogram performed before the hospitalization period analysed, and most of the HDR that collected this information did not determine if the HF was diastolic or systolic. In the post-intervention sample there was a lower percentage of HDR that prescribed angiotensin-converting enzyme inhibitors or angiotensin receptor blocker ii (26% vs 32%, P<.001). In 30% of the pre-intervention sample and 38% of the post-intervention sample there was indication of beta-blockers (P=.027). A short discussion with the physicians responsible for patients with HF improves the inclusion of important data on the diagnosis, prognosis and treatment in the HDR. Copyright © 2014 SECA.

    ABSTRACT: In patients with acute decompensated heart failure (ADHF), both natriuretic peptides and renal impairment predict adverse outcomes. Our aim was to evaluate the complementary prognosis role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and the newly developed Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations based on cystatin C (CysC) for glomerular filtration rate (GFR) estimation in ADHF patients. Renal impairment assessed by CysC-based CKD-EPI equations and natriuretic peptides have complementary prognostic value in ADHF patients. The study included 613 consecutive patients presenting with ADHF. At admission, plasma levels of NT-proBNP and CysC were determined. The GFR was estimated using CysC-based CKD-EPI equations. The primary endpoint was death from any cause and heart failure readmission. During the median follow-up of 365 days (interquartile range, 227-441 days), 323 patients (0.65 %patient-year) died or were readmitted for heart failure. After multivariate adjustment, estimated GFR <60 mL/min/1.73 m(2) and NT-proBNP >3251 pg/mL were independent predictors of adverse outcomes (P < 0.01). The combination of GFR <60 mL/min/1.73 m(2) and NT-proBNP >3251 pg/mL was associated with the highest risk of adverse outcomes. Furthermore, reclassification analyses demonstrated that use of both NT-proBNP and CysC-based CKD-EPI equations resulted in improving the accuracy for adverse outcomes prediction. In patients with ADHF, the combination of NT-proBNP with estimated GFR using CysC-based CKD-EPI equations better predicts outcomes than either parameter alone and adds valuable complementary prognosis information to other established risk factors. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: Renal function is an important prognostic factor in heart failure. The aim of this study was to compare the predictive value of estimated renal function calculated by the Chronic Kidney Disease-Epidemiology Collaboration equation (CKD-EPI) and the abbreviated Modification of Diet in Renal Disease (MDRD-4) equation for long-term all-cause mortality in patients admitted for acute decompensated heart failure (ADHF) with both preserved ejection fraction (HF-PEF) and reduced ejection fraction (HF-REF). We evaluated patients included in the Spanish National Registry of Heart Failure (RICA). RICA is a multicentre, prospective, cohort study that included patients admitted to the Internal Medicine units with ADHF. Estimated glomerular filtration rate (eGFR) was calculated with CKD-EPI and MDRD-4 equations. A total of 1805 patients admitted for ADHF were studied (52% women; median age 80 years, interquartile range 73.9-84.6 years); of these, 1044 (58%) had HF-PEF. eGFR values were lower with the CKD-EPI formula than with the MDRD-4 formula (51 ml/min/1.73 m(2) vs. 55.7 ml/min/1.73 m(2) ; p < 0.001). The two formulas provided independent prognostic information over long-term follow-up, in both HF-PEF and HF-REF patients. However, in HF-PEF patients, CKD-EPI equation was associated with a significant improvement in reclassification analyses (net reclassification improvement 6.78%; p = 0.009). In this clinical cohort of ADHF patients, eGFR as calculated by both the CKD-EPI and the MDRD-4 formulas offered similar prognostic information, irrespective of ejection fraction status, but in HF-PEF patients specifically, the CKD-EPI formula seems to improve clinical risk stratification as compared with MDRD-4. © 2015 John Wiley & Sons Ltd.

    ABSTRACT: Introduction: Ischemic heart disease presents different features in men and women. We analyzed the relation between gender and prognosis in patients who had suffered a high-risk acute coronary syndrome (ACS). Methods: This was a prospective analytical cohort study performed at Lozano Blesa University Hospital, Zaragoza, Spain, of 559 patients diagnosed with high-risk ACS with and without ST-segment elevation according to the American College of Cardiology/American Heart Association guidelines. The sample was divided into two groups by gender and differences in epidemiologic, laboratory, electrocardiographic and echocardiographic variables and treatment were recorded. A Cox's proportional hazard model was applied and 6-month mortality was analyzed as the main variable. Results: The median age was 65.2±12.7 years, and 21.8% were women. Baseline characteristics in women were more unfavorable, with higher GRACE scores, older age, higher prevalence of hypertension, diabetes and heart failure, lower ejection fraction and more renal dysfunction at admission. Women suffered more adverse cardiovascular events (27.9% vs. 15.8%, p=0.002). Sixty-four patients died, 18.9% of the women vs. 9.4% of the men (p=0.004). After multivariate analysis, female gender did not present an independent relation with mortality. Hemoglobin level, renal function, ejection fraction and Killip class >1 presented significant differences. Conclusions: Acute syndrome coronary in women has a worse prognosis than in men. Their adverse course is due to their baseline characteristics and not to their gender.

    ABSTRACT: Changes in N-terminal pro B-type natriuretic peptide (NT-proBNP) levels and cystatin C (CysC) are predictors of adverse outcomes in acute heart failure. This study assess whether NT-proBNP variations might provide independent information in addition to that obtained from CysC levels. NT-proBNP levels were assessed in patients admitted due to acute heart failure using an observational study. Patients were classified as follows: group 1, those with a decrease in NT-proBNP levels of at least 30% from admission to 4 weeks after discharge; group 2, those with no significant changes in levels; and group 3, those who showed an increase in NT-proBNP of 30%. A multivariable Cox regression model and c-statistics were used. The primary end-point was all-cause mortality at 1-year follow-up. A total of 195 patients completed the follow-up. The mortality rate reached 20.5% (40 patients); 14 out of the 32 in group 3. The cumulative incidence of death, according to the change in NT-proBNP and Kaplan-Meier analysis, showed a significant increase in group 3 (log-rank P = 0.004). In the multivariable analysis, NT-proBNP variation for group 3 (hazard ratio 4.27; P <0.001) and for group 2 (hazard ratio 2.19; P = 0.043) in comparison with group 1 were independently associated with all-cause mortality, as well as anemia, hyponatremia, and admission CysC levels. Patients in group 3, and those with levels of serum CysC above the median, were also associated with slight increase in mortality. An increase of at least 30% in NT-proBNP levels after hospitalization is related to all-cause mortality in patients with acute heart failure and provides supplementary prognostic information in patients with high levels of CysC. A decrease in NT-proBNP of at least 30% is a desirable target to achieve.

    ABSTRACT: This study was conducted to determine whether galectin-3 (Gal3), a β-galactoside-binding lectin, has usefulness to predict outcomes in patients with heart failure (HF) and preserved left ventricular ejection fraction (LVEF). We measured Gal3, urea, creatinine and natriuretic peptides on admission in 419 selected patients with HF and LVEF over 45%. The primary endpoint was all-cause mortality and/or readmission at one-year follow-up. Multivariable Cox proportional hazards models were generated for Gal3 and classical risk factors. We also evaluated the reclassification of patients on the basis of the different score category after adding Gal3 levels. A total of 219 patients had combined adverse events, and 129 patients died during the follow-up. Kaplan-Meir survival curve showed significantly increased primary endpoint and all-cause mortality according to quartiles of Gal3 (log rank, P<0.001). Serum Gal3 levels above median (13.8ng/ml) was a significant predictor of primary endpoint risk after adjustment for age, estimated glomerular filtration rate, anemia, diabetes, serum sodium, brain natriuretic peptide levels, NYHA class and urea, respectively (hazard ratio 1.43, 95% CI 1.07-1.91 P=0.015). The reclassification index increased significantly after addition of Gal3 (9.5%, P<0.001) and the integrated discrimination index was 0.022, (P=0.001). The clinical prediction model with Gal3 increased the c-statistic from 0.711 to 0.731 (difference of 0.020, P=0.001). Serum Gal3 is a strong and independent predictor of unfavorable outcomes in patients with HF and preserved LVEF. We also demonstrated the improvement of adding the new biomarker to the model.

    ABSTRACT: Background: Renal dysfunction is common in patients with heart failure (HF) and is associated with high mortality. This relationship is well established in HF and reduced ejection fraction (HFREF), however, it is not fully understood in HF and preserved ejection fraction (HFPEF). The aim of this study was to determine the impact of renal dysfunction on all-cause mortality in HFPEF patients and to evaluate the clinical characteristics of patients that deteriorate renal function in the first year of follow-up. Methods: We evaluated the patients with HFPEF included in the RICA registry. This is a multi-center and prospective cohort study that includes patients admitted for decompensated HF. Estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN) and plasma creatinine concentrations were used for renal function assessment at admission and after one year of follow up. Results: A total of 455 patients (mean age 78±8.1years; 62% women) were included, of whom 265 (58.2%) had eGFR<60mL/min/1.73m(2). After adjustment for covariates, only lower admission eGFR remained significantly predictive of all-cause mortality (HR 2.97; 95% CI 1.59-5.53). After one year of follow-up 16.6% of patients deteriorated at least 25% of eGFR. These patients were more likely to be diabetic (54.5% vs 42.6%; p=0.039) and had a higher rate of prescription of mineralcorticoid receptor antagonist (MRA) agents (47% vs 23.3%; p<0.001). Conclusion: Renal dysfunction is frequently associated with HFPEF. eGFR below normal is strongly associated with mortality. Further decline of renal function is frequent especially among diabetic and patients treated with MRA agents.

    ABSTRACT: Aims: NT-proBNP and renal impairement both predict death in patients with acutely decompensated heart failure (ADHF). We sought to evaluate the complementary prognosis role of NT-proBNP and the newly developed cystatin C-based CKD-EPI equations for estimation of glomerular filtration rate (GFR) in ADHF patients. Methods and results: 614 subjects (age 75±10, male 46%, LVEF 52% [37 to 60]), presenting with ADHF were dichotomized according to NT-proBNP and baseline estimated GFR. Estimated GFR was calculated using cystatin C-based CKD-EPI equations. The primary endpoint was mortality and heart failure hospitalization. Over the study period (median 365 days [interquartile range 227 to 441], 346 patients (56%) died or were rehospitalized for heart failure. After multivariate adjustment, eGFR <60mL/min/1.73m2 and NT-proBNP >3251 pg/mL were independent predictors of adverse outcomes (CKD-EPI cystatin C <60 mL/min/1.73m2, HR 1.54 (95% CI 1.18 to 1.99, p=0.001; CKD-EPI creatinine-cystatin C <60 mL/min/1.73m2, HR 1.57 (95% CI 1.22 to 2.01, p=0.001 and NT-proBNP >3251 pg/mL, HR 1.24 (95% CI 1.01 to 1.54, p=0.04). Other independent predictors were NYHA functional class, age, sodium, diabetes mellitus and chronic obstructive pulmonary disease. Furthermore, the combination of eGFR <60mL/min/1.73m2 and NT-proBNP >3251 pg/mL was associated with the highest risk of adverse outcomes (Figure 1). Finally, reclassfication analyses demonstrated that use of both NT-proBNP and cystatin C-based equations resulted in improving the accuracy for adverse outcomes prediction.
