Project description:BackgroundAlthough noninvasive positive pressure ventilation (NIPPV) for patients with acute decompensated heart failure was introduced almost 20 years ago, the variation in its use among hospitals remains unknown. We sought to define hospital practice patterns of NIPPV use for acute decompensated heart failure and their relationship with intubation and mortality.Methods and resultsWe conducted a cross-sectional study using a database maintained by Premier, Inc., that includes a date-stamped log of all billed items for hospitalizations at >400 hospitals. We examined hospitalizations for acute decompensated heart failure in this database from 2005 to 2010 and included hospitals with annual average volume of >25 such hospitalizations. We identified 384 hospitals that encompassed 524 430 hospitalizations (median annual average volume: 206). We used hierarchical logistic regression models to calculate hospital-level outcomes: risk-standardized NIPPV rate, risk-standardized intubation rate, and in-hospital risk-standardized mortality rate. We grouped hospitals into quartiles by risk-standardized NIPPV rate and compared risk-standardized mortality rates and risk-standardized intubation rates across quartiles. Median risk-standardized NIPPV rate was 6.2% (interquartile range, 2.8%-9.3%; 5th percentile, 0.2%; 95th percentile, 14.8%). There was no clear pattern of risk-standardized mortality rates across quartiles. The bottom quartile of hospitals had higher risk-standardized intubation rate (11.4%) than each of the other quartiles (9.0%, 9.7%, and 9.1%; P<0.02 for all comparisons).ConclusionsSubstantial variation exists among hospitals in the use of NIPPV for acute decompensated heart failure without evidence for differences in mortality. There may be a threshold effect in relation to intubation rates, with the lowest users of NIPPV having higher intubation rates.

Project description:Acute decompensated heart failure (ADHF) is one of the leading causes for hospitalization and mortality. Identifying high risk patients is essential to ensure proper management. Sequential Organ Function Assessment Score (SOFA) is considered an excellent score to predict short-term mortality in sepsis and other life-threatening conditions. To assess the capability of SOFA score in predicting short-term mortality in ADHF. We retrospectively identified patients with first hospitalization with primary diagnosis of ADHF between the years (2008-2018). The SOFA score was calculated for all patients. A total 3232 patients were included in the study. The SOFA score was significantly associated with in-hospital mortality and 30-day mortality. The odds ratios for 1-point increase in the SOFA score were 1.86 (95% CI 1.68-1.96) and 1.627 (95% CI 1.523-1.737) respectively. The SOFA Score demonstrated a good predictive accuracy. The areas under the curve of receiver operating characteristic curves for in-hospital mortality and 30-day mortality were 0.765 (95% CI 0.733-0.798) and 0.706 (95% CI 0.676-0.736) respectively. SOFA score is associated with increased risk of short-term mortality in ADHF. SOFA can be used as a complementary risk score to screen high risk patients who need strict monitoring.

Project description:BackgroundTo investigate the influence of blood pressure (BP) level on short-term prognosis of heart failure (HF), the effect of the BP level on clinical end point events 3 months after discharge was observed.MethodsA retrospective cohort study was performed on 1492 hospitalized HF patients. All patients were divided according to systolic blood pressure (SBP) per 20 mmHg and diastolic blood pressure (DBP) per 10 mmHg. Logistic regression analysis was used to analyze the relationship between BP level and heart failure rehospitalization, cardiac death, all-cause death and a composite end point of heart failure rehospitalization/all-cause death at 3 month follow-up after discharge.ResultsAfter multivariable adjustment, the relationship between SBP and DBP levels and outcomes followed an inverted J curve relationship. Compared with the reference group (110 < SBP≤130 mmHg), the risk of all end point events significantly increased in the SBP≤90 mmHg group included heart failure rehospitalization (OR 8.16, 95%CI 2.88-23.11, P < 0.001), cardiac death (OR 5.43, 95%CI 1.97-14.96, P = 0.001), all-cause death (OR 4.85, 95%CI 1.76-13.36, P = 0.002), and composite end point (OR 2.76, 95%CI 1.03-7.41, P = 0.044). SBP>150 mmHg significantly increased the risk of heart failure rehospitalization (OR 2.67, 95%CI 1.15-6.18, P = 0.022). Compared with.the reference group (65 < DBP≤75 mmHg), cardiac death (OR 2.64, 95%CI 1.15-6.05, P = 0.022) and all-cause death (OR 2.67, 95%CI 1.20-5.93, P = 0.016) was significantly increased in DBP≤55 mmHg group. There was no significant difference among subgroups according to left ventricular ejection fraction (P > 0.05).ConclusionsThere is a significant difference in the short-term prognosis 3 months after discharge in HF patients with different BP levels at discharge. There was an inverted J curve relationship between BP levels and prognosis.

Project description:IntroductionThere is a dearth of comprehensive studies on the association between serum electrolyte and adverse short-term prognosis of Chinese patients with acute decompensated heart failure (ADHF).Patients and methodsA total of 5166 patients with ADHF were divided into four serum electrolyte-related study populations (potassium (n = 5145), sodium (n = 5135), chloride (n = 4966), serum total calcium (STC) (n = 4143)) under corresponding exclusions. Different logistic regression models were utilized to gauge the association between these electrolytes or the number of electrolyte abnormalities and the risk of a composite of all-cause mortality or 30-day heart failure (HF) readmission.ResultsIn multivariable adjusted analysis, patients with potassium below 3.5 mmol/L (odds ratios (ORs) 1.45; 95% confidence interval (CI):1.07-1.95), 4.01-4.50 mmol/L (OR: 1.29, CI: 1.02-1.62), 4.51-5.00 mmol/L (OR: 1.43, CI: 1.08-1.90) and above 5.00 mmol/L (OR: 1.74, CI: 1.21-2.51) had an increased risk of outcome when compared with potassium at 3.50-4.00 mmol/L. Sodium levels were inversely related to the risk of a composite outcome (<130 mmol/L: OR: 2.73 (95% CI, 1.81-4.12); 130-134 mmol/L: OR, 1.97 (CI, 1.45-2.68); 135-140 mmol/L: OR, 1.45 (CI, 1.17-1.81); p for trend < 0.001) in comparison with sodium at 141-145 mmol/L. Chloride < 95 mmol/L corresponded to a higher risk of a composite outcome with an OR of 1.65 (95% CI, 1.16-2.37) in contrast to chloride levels at 101-105 mmol/L. In addition, the adjusted ORs (95% CI) for a composite outcome comparing the STC < 2.00 and 2.00-2.24 vs. 2.25-2.58 mmol/L were 0.98 (0.69-1.43) and 1.13 (0.89-1.44), respectively. Besides that, the number of electrolyte abnormalities was positively related to the risk of a composite outcome (N = 1, OR 1.40, 95% CI: 1.13-1.73; N = 2, OR 2.51, 95% CI: 1.85-3.42; N = 3, OR 2.47, 95% CI: 1.45-4.19; p for trend < 0.001) in comparison with N = 0.ConclusionsA deviation of potassium levels from 3.50 to 4.00 mmol/L, lower sodium levels and hypochloremia were associated with poorer short-term prognosis of ADHF. Furthermore, the number of electrolyte abnormalities positively correlated with adverse short-term prognosis of patients with ADHF. Key MessagesADHF patients with baseline serum potassium at first half part of normal range (3.50-4.00 mmol/L) may herald the lowest risk of recent cardiovascular events.Serum sodium and chloride levels exhibit discrepancies in terms of risk of short-term adverse events of ADHF patients.The number of electrolyte abnormalities is a significant predictor of poor short-term prognosis in patients with ADHF.Clinical trial registration urlhttp://www.chictr.org.cn/showproj.aspx?proj=23139.

Project description:IntroductionThe effectiveness of non-invasive mechanical ventilation (NIV) in the management of COPD patients suffering from acute respiratory failure (ARF) as a consequence of exacerbation of the disease, is well established. However, data on long-term outcomes and their predictors, including the individual response to NIV, are scarce.ObjectivesTo investigate predictors for short- and long-term mortality in this study population.MethodsA retrospective cohort study was performed including all patients admitted to the Medium Respiratory Care Unit of Maastricht University Medical Center in Maastricht, the Netherlands, with hospitalized exacerbation of COPD (H-ECOPD) with ARF requiring NIV for the first time between January 2009 and December 2011. An extensive number of potential predictors of outcomes, including the response to NIV, were determined on admission and during hospitalization. Univariate and multivariate logistic regression was used for statistical analysis.ResultsSeventy-eight consecutive patients with moderate to severe COPD (mean age 71.0 ± 10.7 years; 48.7% males) were included; In-hospital, 1-year and 2-year mortality rates were 14.1%, 43.6% and 56.4%, respectively. Independent risk factors for 2-year mortality were: advanced age (odds ratio(OR) 1.025; confidence interval (CI) 1.002-1.049; P = 0.037), prolonged NIV use more than 8 days (OR:1.054;CI:1.006-1.104; P = 0.027) and no successful response to NIV (OR:2.392;CI:1.297-4.413; P = 0.005).ConclusionPatients with an H-ECOPD requiring NIV for the first time, constitute a severely ill patient group with high in-hospital and 2-year mortality. This study identified advanced age, NIV use more than 8 days and unsuccessful response to NIV as clinical important independent predictors for long-term mortality.

Project description:BackgroundPatients admitted with acute decompensated heart failure (ADHF) have a poor prognosis and poor quality of life due to dyspnea and edema. Tolvaptan, a vasopressin V2 receptor antagonist, is an effective water diuretic. This study aimed to evaluate the efficacy and safety of a short course of tolvaptan to treat volume overload in patients with ADHF.MethodsWe conducted a phase III, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of a short course of tolvaptan (15 mg/day for 4 days) in hospitalized ADHF patients with volume overload despite the use of conventional diuretics. The primary end-point was the change in body weight after 4 days of treatment. The secondary end-points were the change in intake/output balance, change in serum sodium/potassium concentrations, physician/patient assessed signs and symptoms of heart failure after 4 days of treatment, and all-cause mortality in 1 month.ResultsA total of 110 patients were screened, and 91 were randomized to receive 15 mg/day of tolvaptan for 4 days (n = 46) or matching placebo (n = 45). Compared to the placebo-treated patients, tolvaptan significantly reduced body weight (-1.36 ± 2.13 kg in the tolvaptan group vs. -0.59 ± 1.27 kg in the placebo group, p = 0.0394). The tolvaptan group also had a negative intake/urine volume balance compared to the placebo group (-509.3 ± 2788.2 ml vs. 975.5 ± 1903.1 ml, p = 0.0059). The safety profile of tolvaptan was acceptable.ConclusionsTolvaptan significantly reduced volume overload in hospitalized ADHF patients with volume overload despite the use of conventional diuretics.

Project description:B-type natriuretic peptide (BNP) has prognostic significance in heart failure (HF), and reductions in BNP may predict clinical improvement. However, there are limited data regarding the prognostic value of BNP during short-term follow-up. The aim of this study was to evaluate the relationship between short-term follow-up BNP and mortality after discharge in patients with HF.We analyzed 427 patients hospitalized with HF from the Wonju Severance Christian Hospital Heart Failure Registry from April 2011 to December 2013, with a planned follow-up period through February 2016. Of the 427 patients, 240 (mean age, 75 years; 102 males, 42.5%) had BNP measured on admission and within the short-term follow-up period (3 months). We compared all-cause mortality during the clinical follow-up period (median length of follow-up, 709.5 days) according to the median value of BNP on admission (as a baseline value) and over a short-term follow-up period after discharge.Median BNP at admission was 816.5 pg/ml, and median follow-up BNP was 369.7 pg/ml. Multivariate analysis revealed a positive association between risk of death and high BNP. High BNP during follow-up was significantly associated with a greater risk of all-cause mortality compared to low BNP (P < 0.001). Initial BNP was not significantly associated with all-cause mortality. A multivariate model showed that follow-up BNP and percent change in BNP were independently associated with all-cause mortality after adjustment for covariates. Of the 3 BNP measurement strategies, BNP after discharge (IDI of 0.072, P < .0001 and NRI of 0.707, P < .0001) and percent change in BNP (IDI of 0.113, P < .0001 and NRI of 0.782, P < .0001) demonstrated the greatest increase in discrimination and net reclassification for mortality. Unfortunately, we did not find any significant value with initial BNP. Kaplan-Meier survival analysis was performed to assess mortality stratified by BNP according to the median value, high median of follow-up BNP and percent change in BNP were associated with significantly higher mortality compared to the below median (log-rank, p < 0.001).Short-term follow-up BNP and percent change in BNP level are significant prognostic factors of all-cause mortality. These values will be clinically useful when evaluating prognosis in hospitalized patients with heart failure.

Project description:This study aims at comparing the very short-term effects of conventional and noisy (variable) pressure support ventilation (PSV) in mechanically ventilated patients with acute hypoxemic respiratory failure.Thirteen mechanically ventilated patients with acute hypoxemic respiratory failure were enrolled in this monocentric, randomized crossover study. Patients were mechanically ventilated with conventional and noisy PSV, for one hour each, in random sequence. Pressure support was titrated to reach tidal volumes approximately 8 mL/kg in both modes. The level of positive end-expiratory pressure and fraction of inspired oxygen were kept unchanged in both modes. The coefficient of variation of pressure support during noisy PSV was set at 30%. Gas exchange, hemodynamics, lung functional parameters, distribution of ventilation by electrical impedance tomography, breathing patterns and patient-ventilator synchrony were analyzed.Noisy PSV was not associated with any adverse event, and was well tolerated by all patients. Gas exchange, hemodynamics, respiratory mechanics and spatial distribution of ventilation did not differ significantly between conventional and noisy PSV. Noisy PSV increased the variability of tidal volume (24.4?±?7.8% vs. 13.7?±?9.1%, P?<0.05) and was associated with a reduced number of asynchrony events compared to conventional PSV (5 (0 to 15)/30 min vs. 10 (1 to 37)/30 min, P?<0.05).In the very short term, noisy PSV proved safe and feasible in patients with acute hypoxemic respiratory failure. Compared to conventional PSV, noisy PSV increased the variability of tidal volumes, and was associated with improved patient-ventilator synchrony, at comparable levels of gas exchange.ClinicialTrials.gov, NCT00786292.

Project description:Background: We sought to explore the effects of previous heart failure (HF) hospitalization on mortality in patients hospitalized for acute decompensated HF (ADHF) in a large Japanese contemporary observational database. Methods and Results: We prospectively enrolled consecutive patients with ADHF in 19 participating hospitals between October 2014 and March 2016. Of 4,056 patients, 1,442 patients (35.4%) had at least 1 previous HF hospitalization (previous hospitalization group), while 2,614 patients (64.5%) did not have a history of HF hospitalization (de novo hospitalization group). Patients with previous hospitalization were older and more often had comorbidities such as anemia, and renal failure than those without. The cumulative 1-year incidence of all-cause death was significantly higher in the previous hospitalization group than in the de novo hospitalization group (28% vs. 19%, P<0.001). After adjusting confounders, the excess risk of the previous hospitalization group relative to the de novo hospitalization group for all-cause death remained significant (HR, 1.28; 95% CI: 1.10-1.50, P=0.001). The excess risk was significant in patients without advanced age, anemia, or renal failure, but not significant in patients with these comorbidities, with significant interaction. Increase in the number of hospitalizations was associated with an increased risk for mortality. Conclusions: In a contemporary ADHF cohort in Japan, repeated hospitalization was associated with an increasing, higher risk for 1-year mortality.

Project description:The aim of the present study was to examine potential differences in the regulation of myocardial ECM constituents, in mice that develop hypertrophy only (ABnonHF) and in mice that develop overt heart failure (ABHF) as response to pressure overload. Seven weeks old male C57BL/6 mice were subjected to aortic banding (AB) or sham operation (sAB), with sacrifice 4 weeks after banding. Prior to sacrifice, cardiac function and geometry were evaluated by echocardiography. Animals with comparable gradients over the banded ascending aorta, comparable cardiac output and heart rate were divided into two groups: ABnonHF and ABHF. Our criterion for dividing AB animals into these two groups was based on lung weight and left atrial diameter (LAD), as an increase in these parameters most likely is due to pulmonary congestion. Heart failure (HF) was defined as an increase in lung weight and LAD defining ABnonHF as lung weight/tibia length M-bM-^IM-$ 10.5 mg/mm and LAD M-bM-^IM-$ 2.0 mm and ABHF as lung weight/tibia length M-bM-^IM-% 15 mg/mm and LAD M-bM-^IM-% 2.4 mm. Microarray screening was performed in 7 mice from each AB group and in 5 sAB mice. Sham was used as control.
