Admission systolic blood pressure as a prognostic predictor of acute decompensated heart failure: A report from the KCHF registry.
Ontology highlight
ABSTRACT: Background
Admission systolic blood pressure has emerged as a predictor of postdischarge outcomes of patients with acute decompensated heart failure; however, its validity in varied clinical conditions of this patient subset is unclear. The aim of this study was to further explore the prognostic value of admission systolic blood pressure in patients with acute decompensated heart failure.Methods
The Kyoto Congestive Heart Failure (KCHF) registry is a prospective, observational, multicenter cohort study enrolling consecutive patients with acute decompensated heart failure from 19 participating hospitals in Japan. Clinical characteristics at baseline and prognosis were examined by the following value range of admission systolic blood pressure: <100, 100-139, and ≥140 mmHg. The primary outcome measure was defined as all-cause death after discharge. Subgroup analyses were done for prior hospitalization for heart failure, hypertension, left ventricular ejection fraction, and medications at discharge. We excluded patients with acute coronary syndrome or insufficient data.Results
We analyzed 3564 patients discharged alive out of 3804 patients hospitalized for acute decompensated heart failure. In the entire cohort, lower admission systolic blood pressure was associated with poor outcomes (1-year cumulative incidence of all-cause death: <100 mmHg, 26.8%; 100-139 mmHg, 20.2%; and ≥140 mmHg, 15.1%, p<0.001). The magnitude of the effect of lower admission systolic blood pressure for postdischarge all-cause death was greater in patients with prior hospitalization for heart failure, heart failure with reduced left ventricular ejection fraction, and β-blocker use at discharge than in those without.Conclusions
Admission systolic blood pressure is useful for postdischarge risk stratification in patients with acute decompensated heart failure. Its magnitude of the effect as a prognostic predictor may differ across clinical conditions of patients.

Project description:Background Heart failure (HF) is a known risk factor for ischemic stroke, but data regarding ischemic stroke during hospitalization for acute decompensated HF (ADHF) are limited. Methods and Results We analyzed the data from a multicenter registry (Kyoto Congestive Heart Failure [KCHF] Registry) that enrolled 4056 consecutive patients with ADHF in Japan (mean age, 78 years; men, 2238 patients [55%]; acute coronary syndrome [ACS], 239 patients [5.9%]). We investigated the incidence and predictors of ischemic stroke during hospitalization for ADHF. During the hospitalization, 63 patients (1.6%) developed ischemic stroke. The median interval from admission to the onset of ischemic stroke was 7 [interquartile range: 2-14] days, and the most common underlying cause was cardioembolism (64%). Men (OR, 1.87; 95%CI, 1.11-3.24), ACS (OR, 2.31; 95%CI, 1.01-4.93), absence of prior HF hospitalization (OR, 2.21; 95%CI, 1.24-4.21), and high B-type natriuretic peptide (BNP)/N-terminal proBNP (NT-proBNP) levels (above the median) at admission (OR, 3.15; 95%CI, 1.84-5.60) were independently associated with ischemic stroke. In patients without ACS, the independent risk factors for ischemic stroke were fully consistent with those in the main analysis. Higher quartiles of BNP/NT-proBNP levels were significantly associated with higher incidence of ischemic stroke (P for trend, <0.001). Patients with ischemic stroke showed higher in-hospital mortality, longer length of hospital stay, and poorer functional status at discharge. Conclusions During hospitalization for ADHF, 1.6% of the patients developed ischemic stroke. Men, ACS, absence of prior HF hospitalization, and high BNP/NT-proBNP levels at admission were independently associated with ischemic stroke.

Project description:Background No studies have explored the association between newly diagnosed infections after admission and clinical outcomes in patients with acute heart failure. We aimed to explore the factors associated with newly diagnosed infection after admission for acute heart failure, and its association with in-hospital and post-discharge clinical outcomes. Methods and Results Among 4056 patients enrolled in the Kyoto Congestive Heart Failure registry, 2399 patients without any obvious infectious disease upon admission were analyzed. The major in-hospital and post-discharge outcome measures were all-cause deaths. There were 215 patients (9.0%) with newly diagnosed infections during hospitalization, and 2184 patients (91.0%) without infection during hospitalization. The factors independently associated with a newly diagnosed infection were age ≥80 years, acute coronary syndrome, non-ambulatory status, hyponatremia, anemia, intubation, and patients who were not on loop diuretics as outpatients. The newly diagnosed infection group was associated with a higher incidence of in-hospital mortality (16.3% and 3.2%, P<0.001) and excess adjusted risk of in-hospital mortality (odds ratio, 6.07 [95% CI, 3.61-10.19], P<0.001) compared with the non-infection group. The newly diagnosed infection group was also associated with a higher 1-year incidence of post-discharge mortality (19.3% in the newly diagnosed infection group and 13.6% in the non-infection group, P<0.001) and excess adjusted risk of post-discharge mortality (hazard ratio, 1.49 [95% CI, 1.08-2.07], P=0.02) compared with the non-infection group. Conclusions Elderly patients with multiple comorbidities were associated with the development of newly diagnosed infections after admission for acute heart failure. Newly diagnosed infections after admission were associated with higher in-hospital and post-discharge mortality in patients with acute heart failure.

Project description:AimsThe association between sex and long-term outcome in patients hospitalized for acute decompensated heart failure (ADHF) has not been fully studied yet in Japanese population. The aim of this study was to determine differences in baseline characteristics and management of patients with ADHF between women and men and to compare 1-year outcomes between the sexes in a large-scale database representing the current real-world clinical practice in Japan.Methods and resultsKyoto Congestive Heart Failure registry is a prospective cohort study enrolling consecutive patients hospitalized for ADHF in Japan among 19 centres. Baseline characteristics, clinical presentation, management, and 1-year outcomes were compared between men and women. A total of 3728 patients who were alive at discharge constituted the current study population. There were 1671 women (44.8%) and 2057 men. Women were older than men [median (IQR): 83 (76-88) years vs. 77 (68-84) years, P < 0.0001]. Hypertensive and valvular heart diseases were more prevalent in women than in men (28.0% vs. 22.5%, P = 0.0001; and 26.9% vs. 14.0%, P < 0.0001, respectively), whereas ischaemic aetiology was less prevalent in women than in men (20.0% vs. 32.5%, P < 0.0001). Women less often had reduced left ventricular ejection fraction (<40%) than men (27.5% vs. 45.1%, P < 0.0001). The cumulative incidence of all-cause death or hospitalization for heart failure was not significantly different between women and men (33.6% vs. 34.3%, P = 0.71), although women were substantially older than men. After multivariable adjustment, the risk of all-cause death or hospitalization for heart failure was significantly lower among women (adjusted hazard ratio: 0.84, 95% confidence interval: 0.74-0.96, P = 0.01).ConclusionsWomen with heart failure were older and more often presented with preserved EF with a non-ischaemic aetiology and were associated with a reduced adjusted risk of 1-year mortality compared with men in the Japanese population.

Project description:AimsThere is a scarcity of data on the post-discharge prognosis in acute heart failure (AHF) patients with a low-income but receiving public assistance. The study sought to evaluate the differences in the clinical characteristics and outcomes between AHF patients receiving public assistance and those not receiving public assistance.Methods and resultsThe Kyoto Congestive Heart Failure registry was a physician-initiated, prospective, observational, multicentre cohort study enrolling 4056 consecutive patients who were hospitalized due to AHF for the first time between October 2014 and March 2016. The present study population consisted of 3728 patients who were discharged alive from the index AHF hospitalization. We divided the patients into two groups, those receiving public assistance and those not receiving public assistance. After assessing the proportional hazard assumption of public assistance as a variable, we constructed multivariable Cox proportional hazard models to estimate the risk of the public assistance group relative to the no public assistance group. There were 218 patients (5.8%) receiving public assistance and 3510 (94%) not receiving public assistance. Patients in the public assistance group were younger, more frequently had chronic coronary artery disease, previous heart failure hospitalizations, current smoking, poor medical adherence, living alone, no occupation, and a lower left ventricular ejection fraction than those in the no public assistance group. During a median follow-up of 470 days, the cumulative 1 year incidences of all-cause death and heart failure hospitalizations after discharge did not differ between the public assistance group and no public assistance group (13.3% vs. 17.4%, P = 0.10, and 28.3% vs. 23.8%, P = 0.25, respectively). After adjusting for the confounders, the risk of the public assistance group relative to the no public assistance group remained insignificant for all-cause death [hazard ratio (HR), 0.97; 95% confidence interval (CI), 0.69-1.32; P = 0.84]. Even after taking into account the competing risk of all-cause death, the adjusted risk within 180 days in the public assistance group relative to the no public assistance group remained insignificant for heart failure hospitalizations (HR, 0.93; 95% CI, 0.64-1.34; P = 0.69), while the adjusted risk beyond 180 days was significant (HR, 1.56; 95% CI, 1.07-2.29; P = 0.02).ConclusionsThe AHF patients receiving public assistance as compared with those not receiving public assistance had no significant excess risk for all-cause death at 1 year after discharge or a heart failure hospitalization within 180 days after discharge, while they did have a significant excess risk for heart failure hospitalizations beyond 180 days after discharge.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/NCT02334891 (NCT02334891) and https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000017241 (UMIN000015238).

Project description:BackgroundThe association of systolic blood pressure (SBP) with mortality in heart failure (HF) patients is paradoxical, and the time points of baseline SBP are also different across prior studies. We hypothesized that the levels of SBP at admission and at discharge had different associations with postdischarge events.MethodsThe study population included patients hospitalized for decompensated HF in the Heart Failure Center of Fuwai Hospital from January 1, 2009 to December 31, 2014. The primary outcome was a composite of cardiovascular (CV) death and heart transplantation. Multivariate Cox proportional-hazards and restricted cubic spline analyses were used to assess the relationships between SBP at different time points and outcomes.ResultsIn total, 2005 patients were included with a median follow-up of 48.4 months. The median age was 59 years, and 69.9% were male. Multivariate Cox analyses showed that compared with SBP < 105 mmHg, higher SBP at admission was associated with better long-term primary outcome (105-119 mmHg, HR = 0.764, P = 0.005; 120-134 mmHg, HR = 0.658, P < 0.001; ≥ 135 mmHg, HR = 0.657, P = 0.001). Patients whose discharge SBP was higher than 135 mmHg had a similar primary outcome as those with SBP < 105 mmHg (HR = 0.969, P = 0.867), and the results remained unchanged even after adjusting for admission SBP (HR = 1.235, P = 0.291). The results of restricted cubic spline analysis indicated similar associations.ConclusionsLower but not higher SBP at admission is associated with more CV deaths/heart transplantations (a reverse J-shaped curve). In contrast, there is a U-shaped association between discharge SBP and CV mortality/heart transplantation.

Project description:BackgroundComplicated pathophysiology makes it difficult to identify the prognosis of heart failure with preserved ejection fraction (HFpEF). While plasma osmolality has been reported to have prognostic importance, mainly in heart failure with reduced ejection fraction (HFrEF), its prognostic meaning for HFpEF has not been elucidated.MethodsWe prospectively studied 960 patients in PURSUIT-HFpEF, a multicenter observational study of acute decompensated HFpEF inpatients. We divided patients into three groups according to the quantile values of plasma osmolality on admission. During a follow-up averaging 366 days, we examined the primary composite endpoint of cardiac mortality or heart failure re-admission using Kaplan-Meier curve analysis and Cox proportional hazard testing.Results216 (22.5%) patients reached the primary endpoint. Kaplan-Meier curve analysis revealed that the highest quantile of plasma osmolality on admission (higher than 300.3 mOsm/kg) was significantly associated with adverse outcomes (Log-rank P = 0.0095). Univariable analysis in the Cox proportional hazard model also revealed significantly higher rates of adverse outcomes in the higher plasma osmolality on admission (hazard ratio [HR] 7.29; 95% confidence interval [CI] 2.25-23.92, P = 0.0009). Multivariable analysis in the Cox proportional hazard model also showed that higher plasma osmolality on admission was significantly associated with adverse outcomes (HR 5.47; 95% CI 1.46-21.56, P = 0.0113) independently from other confounding factors such as age, gender, comorbid of atrial fibrillation, hypertension history, diabetes, anemia, malnutrition, E/e', and N-terminal pro-B-type natriuretic peptide elevation.ConclusionsHigher plasma osmolality on admission was prognostically important for acute decompensated HFpEF inpatients.

Project description:AimsLittle is known about the characteristics and outcomes of patients who undergo coronary angiography during heart failure (HF) hospitalization, as well as those with coronary stenosis, and those who underwent coronary revascularization.Methods and resultsWe analysed 2163 patients who were hospitalized for HF without acute coronary syndrome or prior HF hospitalization. We compared patient characteristics and 1 year clinical outcomes according to (i) patients with versus without coronary angiography, (ii) patients with versus without coronary stenosis, and (iii) patients with versus without coronary revascularization. The primary outcome measure was the composite of all-cause death or HF hospitalization. Coronary angiography was performed in 37.0% of patients. In the multivariable logistic regression analysis, factors independently associated with coronary angiography were age < 80 years [adjusted odds ratio (OR) = 1.76, 95% confidence interval (CI) = 1.41-2.20, P < 0.001], men (adjusted OR = 1.28, 95% CI = 1.03-1.59, P = 0.02), diabetes (adjusted OR = 1.27, 95% CI = 1.02-1.60, P = 0.04), no atrial fibrillation or flutter (adjusted OR = 1.45, 95% CI = 1.17-1.82, P < 0.001), no prior device implantation (adjusted OR = 1.81, 95% CI = 1.13-2.91, P = 0.01), current smoking (adjusted OR = 1.40, 95% CI = 1.05-1.87, P = 0.02), no cognitive dysfunction (adjusted OR = 1.90, 95% CI = 1.34-2.69, P < 0.001), ambulatory status (adjusted OR = 2.89, 95% CI = 2.03-4.10, P < 0.001), HF with reduced ejection fraction (adjusted OR = 1.55, 95% CI = 1.24-1.93, P < 0.001), estimated glomerular filtration rate ≥ 30 mL/min/1.73 m2 (adjusted OR = 1.93, 95% CI = 1.45-2.58, P < 0.001), no anaemia (adjusted OR = 1.27, 95% CI = 1.02-1.59, P = 0.04), and no prescription of β-blockers prior to admission (adjusted OR = 1.32, 95% CI = 1.03-1.68, P = 0.03). Patients who underwent coronary angiography had a lower risk of the primary outcome [adjusted hazard ratio (HR) = 0.70, 95% CI = 0.58-0.85, P < 0.001]. Among the patients who underwent coronary angiography, those with coronary stenosis (38.9%) did not have lower risk of the primary outcome measure than those without coronary stenosis (adjusted HR = 0.93, 95% CI = 0.65-1.32, P = 0.68). Among the patients with coronary stenosis, those with coronary revascularization (54.3%) did not have higher risk of the primary outcome measure than those without coronary revascularization (adjusted HR = 1.36, 95% CI = 0.84-2.21, P = 0.22).ConclusionsIn patients with acute HF, patients who underwent coronary angiography had a lower risk of clinical outcomes and were significantly different from those who did not undergo coronary angiography.

Project description:AimsTo determine the relationship between admission systolic blood pressure (SBP) and mortality in older patients hospitalized for heart failure (HF) and among various subgroups.Methods and resultsWe evaluated the independent association between initial SBP and 30-day and 1-year mortality, and potential interactions by age, gender, race, previous hypertension, and left ventricular dysfunction using multivariable logistic regression in the National Heart Failure Project, a database of Medicare patients >65 years old recruited from 1998 through 2001. Among 56 942 patients, mean admission SBP was 147.0 + or - 92.3 mmHg, 15% presenting with SBP >180 mmHg. Systolic blood pressure showed an inverse relationship with 30-day and 1-year mortality rates in all subgroups analysed. Using admission SBP of 120-149 mmHg as the reference, the adjusted odds ratios (95% confidence intervals) for 1-year mortality were 2.18 (1.77-2.69) for SBP <90 mmHg, 1.57 (1.47-1.69) for SBP 90-119 mmHg, 0.71 (0.67-0.76) for SBP 150-179 mmHg, 0.63 (0.57-0.68) for SBP 180-209 mmHg, and 0.51 (0.44-0.59) for SBP > or = 210 mmHg.ConclusionHigher SBP on admission is associated with significant lower 30-day and 1-year mortality in patients hospitalized for HF. The relationship is strong, graded, independent of other clinical factors and consistent among subgroups.

Project description:AimsThe study sought to investigate the association between admission systolic blood pressure (SBP) and 1-year clinical outcomes in patients hospitalized for heart failure (HF) and in subgroups.MethodsThis study was based on the China Patient-centred Evaluative Assessment of Cardiac Events Prospective Heart Failure Study, which prospectively enrolled patients hospitalized for HF in 52 hospitals from 20 provinces in China between August 2016 and May 2018. Patients were divided into four groups according to the quartiles of SBP at admission. The multivariable Cox proportional hazards regression models were fitted to examine the association between admission SBP and all-cause death and HF readmission within 1 year after the index hospitalization. Restricted cubic splines were used to explore the non-linear association between SBP and the clinical outcomes.ResultsAmong 4896 patients, those with lower admission SBP were younger, more likely to be male, have left ventricular ejection fraction <40%, and receive β-blockers, aldosterone antagonists, and diuretics. After adjustment for potential confounders, lower admission SBP was significantly associated with higher all-cause death and there is no threshold, while we only observed such an association with HF readmission when admission SBP was lower than 120 mmHg. Compared with the 4th SBP quartile, patients in the 1st SBP quartile had higher risk of all-cause death (hazard ratio, 1.85; 95% confidence interval 1.48-2.33; P < 0.001) and HF readmission (hazard ratio, 1.40; 95% confidence interval 1.19-1.65, P < 0.001). These associations were consistent in most subgroups, such as age, sex, and left ventricular ejection fraction.ConclusionsIn patients hospitalized for HF, lower admission SBP portends an increased risk of 1 year all-cause death and HF readmission, and these associations were consistent among subgroups.

Project description:BACKGROUND:An enhanced inflammatory response predicts worse outcomes in heart failure (HF). We hypothesized that administration of IL-1 (interleukin-1) receptor antagonist (anakinra) could inhibit the inflammatory response and improve peak aerobic exercise capacity in patients with recently decompensated systolic HF. METHODS AND RESULTS:We randomly assigned 60 patients with reduced left ventricular ejection fraction (<50%) and elevated C-reactive protein levels (>2 mg/L), within 14 days of hospital discharge, to daily subcutaneous injections with anakinra 100 mg for 2 weeks, 12 weeks, or placebo. Patients underwent measurement of peak oxygen consumption (Vo2 [mL/kg per minute]) and ventilatory efficiency (the VE/Vco2 slope). Treatment with anakinra did not affect peak Vo2 or VE/Vco2 slope at 2 weeks. At 12 weeks, patients continued on anakinra showed an improvement in peak Vo2 from 14.5 (10.5-16.6) mL/kg per minute to 16.1 (13.2-18.6) mL/kg per minute (P=0.009 for within-group changes), whereas no significant changes occurred within the anakinra 2-week or placebo groups. The between-groups differences, however, were not statistically significant. The incidence of death or rehospitalization for HF at 24 weeks was 6%, 31%, and 30%, in the anakinra 12-week, anakinra 2-week, and placebo groups, respectively (log-rank test P=0.10). CONCLUSIONS:No change in peak Vo2 occurred at 2 weeks in patients with recently decompensated systolic HF treated with anakinra, whereas an improvement was seen in those patients in whom anakinra was continued for 12 weeks. Additional larger studies are needed to validate the effects of prolonged anakinra on peak Vo2 and rehospitalization for HF. CLINICAL TRIAL REGISTRATION:URL: http://www.clinicaltrials.gov.
