Cobalt protoporphyrin promotes heme oxygenase 1 expression and ameliorates cardiac dysfunction in long-term fasting mice.

BACKGROUND: The association between malnutrition and cardiac dysfunction has been reported. Heme oxygenase (HO)-1 played protective roles in the animals functioning as a myocardial infarction, heart failure, or cardiomyopathy model. We hypothesized that the administration of HO-1 inducer, cobalt protoporphyrin (CoPP) reduces oxidative stress and ameliorates cardiac systolic dysfunction in long-term fasting mice. METHODS: C57BL/6 J mice were classified into three groups: fed mice (fed group), 48-h fasting mice with a single intraperitoneal injection of the corresponding vehicle (fasting group), and 48-h fasting mice with a single intraperitoneal injection of 5 mg/kg CoPP (CoPP group). RESULTS: The fasting group showed a significant increase in heme and 4-hydroxy-2-nonenal (4HNE) protein in the heart tissue, and reduced left ventricular ejection fraction (LVEF) when compared with the fed group. The CoPP group showed significantly increased protein levels of nuclear factor-erythroid 2-related factor 2 and HO-1, and increased mRNA expression levels of HO-1, peroxisome proliferator-activated receptor gamma coactivator 1-alpha, forkhead box protein O1, sirtuin-1, cyclooxygenase 2, and superoxide dismutase 2, and reduced levels of heme and 4HNE protein when compared with the fasting group. LVEF were significantly higher in the CoPP group than in the fasting group. CONCLUSIONS: Administration of CoPP reduced heme accumulation and oxidative stress, and ameliorated cardiac systolic dysfunction in long-term fasting mice. This study suggests that heme accumulation may be associated with impaired cardiac function induced by long-term fasting and that HO-1 may be a key factor or therapeutic target.

Prognostic Impact of Hyperpolypharmacy Due to Noncardiovascular Medications in Patients After Acute Decompensated Heart Failure　- Insights From the Clue of Risk Stratification in the Elderly Patients With Heart Failure (CURE-HF) Registry.

BACKGROUND: Hyperpolypharmacy is associated with adverse outcomes in older adults, but because literature on its association with cardiovascular (CV) outcomes after acute decompensated heart failure (ADHF) is sparse, we investigated the relationships among hyperpolypharmacy, medication class, and death in patients with HF.Methods and Results: We evaluated the total number of medications prescribed to 884 patients at discharge following ADHF. Patients were categorized into nonpolypharmacy (<5 medications), polypharmacy (5-9 medications), and hyperpolypharmacy (≥10 medications) groups. We examined the relationship of polypharmacy status with the 2-year mortality rate. The proportion of patients taking ≥5 medications was 91.3% (polypharmacy, 55.3%; hyperpolypharmacy, 36.0%). Patients in the hyperpolypharmacy group showed worse outcomes than patients in the other 2 groups (P=0.002). After multivariable adjustment, the total number of medications was significantly associated with an increased risk of death (hazard ratio [HR] per additional increase in the number of medications, 1.05; 95% confidence interval [CI], 1.01-1.10; P=0.027). Although the number of non-CV medications was significantly associated with death (HR, 1.07; 95% CI, 1.02-1.13; P=0.01), the number of CV medications was not (HR, 1.01; 95% CI, 0.92-1.10; P=0.95). CONCLUSIONS: Hyperpolypharmacy due to non-CV medications was associated with an elevated risk of death in patients after ADHF, suggesting the importance of a regular review of the prescribed drugs including non-CV medications.

The characteristics and outcomes in patients with acute heart failure who used tolvaptan: from KCHF registry.

AIMS: The use of tolvaptan is increasing in clinical practice in Japan. However, the characteristics of patients who used tolvaptan and the timing of its use in patients with acute heart failure (AHF) are not fully elucidated. METHODS AND RESULTS: Among consecutive 4056 patients in the Kyoto Congestive Heart Failure registry, we analysed 3802 patients after excluding patients on dialysis, prior or unknown tolvaptan use at admission, and unknown timing of tolvaptan use, and we divided them into two groups: tolvaptan use (N = 773) and no tolvaptan use (N = 3029). The prevalence of tolvaptan use varied widely from 48.7% to 0% across the participating centres. Factors independently associated with tolvaptan use were diabetes, poor medical adherence, oedema, pleural effusion, hyponatraemia, estimated glomerular filtration rate < 30 mL/min/1.73 m2 , moderate/severe tricuspid regurgitation, dobutamine infusion within 24 h, and additional inotropes infusion beyond 24 h after admission. The mortality rate at 90 days after admission was significantly higher in the tolvaptan use group than in the no tolvaptan use group (14.3% vs. 8.6%, P = 0.049). However, after adjustment, the excess mortality risk of tolvaptan use relative to no tolvaptan use was no longer significant (hazard ratio = 1.53, 95% confidence interval = 0.77-3.02, P = 0.22). Patients with tolvaptan use had a longer hospital stay [median (interquartile range): 22 (15-34) days vs. 15 (11-21) days, P < 0.0001] and a higher prevalence of worsening renal failure (47.0% vs. 31.8%, P < 0.0001) and worsening heart failure (24.8% vs. 14.4%, P < 0.0001) than those without. CONCLUSIONS: AHF patients with tolvaptan use had more congestive status with poorer in-hospital outcomes and higher short-term mortality than those without tolvaptan use.

Weight loss during follow-up in patients with acute heart failure: From the KCHF registry.

BACKGROUNDS: The prognostic implication of weight loss after discharge from acute heart failure (AHF) remains unclear. We sought to investigate the association of weight loss between discharge and 6-month visit with subsequent clinical outcomes in patients with AHF. METHODS: We analyzed 686 patients with AHF in the prospective longitudinal follow-up study derived from the Kyoto Congestive Heart Failure registry, and divided them into 2 groups based on the weight loss at 6-month index visit. We defined the weight loss as ≥ 5% decrease in body weight from discharge to 6-month index visit. RESULTS: There were 90 patients (13.1%) with a weight loss at 6-month visit. Patients in the weight loss group compared with those in the no weight loss group had higher body weight at discharge and lower body weight at 6-mont visit. Patients in the weight loss group had a lower systolic blood pressure, higher brain-type natriuretic peptide, lower serum albumin, lower hemoglobin, higher prevalence of heart failure with reduced ejection fraction at 6-month visit, and a lower prescription rate of inhibitors of renin-angiotensin system than those in the no weight loss group. The cumulative 6-month incidence of all-cause death was significantly higher in the weight loss group than in the no weight loss group (14.2% and 4.3%, log-rank P<0.001). The excess adjusted risk of the weight loss group relative to the no weight loss group remained significant for all-cause death (HR 2.39, 95%CI 1.01-5.65, P = 0.048). CONCLUSION: Body weight loss of ≥5% at 6-month visit after discharge was associated with subsequent all-cause death in patients with AHF.

Association between changes in loop diuretic dose and outcomes in acute heart failure.

AIMS: Little is known about the association between the starting of or dose changes in loop diuretics during acute heart failure (AHF) hospitalization and post-discharge outcomes. We investigated the clinical impact of starting loop diuretics and changing the loop diuretics dose during hospitalization on post-discharge outcomes. METHODS AND RESULTS: From the Kyoto Congestive Heart Failure registry, 3665 consecutive patients hospitalized for HF and discharged alive were included in this study. We analysed 1906 patients without loop diuretics on admission and were discharged alive and 1759 patients who received loop diuretics on admission and were discharged alive. The primary outcome measure was all-cause death. Of the 1906 patients without loop diuretics on admission, 1366 (71.7%) patients started loop diuretics during the index AHF hospitalization. Starting loop diuretics was not associated with lower post-discharge mortality [adjusted hazard ratio (HR) 0.92, 95% confidence interval (CI) 0.68-1.25]. Of the 1759 patients who received loop diuretics on admission, loop diuretic dose was decreased in 23.8%, unchanged in 44.6%, and increased in 31.6% of the patients. Changes in the dose at discharge compared with no change in dose were not associated with lower risk of post-discharge mortality (decrease relative to no change: adjusted HR 0.98, 95% CI 0.76-1.28; increase relative to no change: adjusted HR 1.00, 95% CI 0.78-1.27). Compared with no loop diuretics at discharge, a loop diuretics dose of ≥80 mg at discharge was associated with higher post-discharge mortality risk. CONCLUSIONS: In patients with AHF, we found no association between the starting of loop diuretics and post-discharge outcomes and between dose changes and post-discharge outcomes.

Tricuspid regurgitation in elderly patients with acute heart failure: insights from the KCHF registry.

AIMS: Several studies demonstrated that tricuspid regurgitation (TR) is associated with poor clinical outcomes. However, data on patients with TR who experienced acute heart failure (AHF) remains scarce. The purpose of this study is to evaluate the association between TR and clinical outcomes in patients admitted with AHF, using a large-scale Japanese AHF registry. METHODS AND RESULTS: The current study population consisted of 3735 hospitalized patients due to AHF in the Kyoto Congestive Heart Failure (KCHF) registry. TR grades were assessed according to the routine clinical practice at each participating centre. We compared the baseline characteristics and outcomes according to the severity of TR. The primary outcome was all-cause death. The secondary outcome was hospitalization for heart failure (HF). The median age of the entire study population was 80 (interquartile range: 72-86) years. One thousand two hundred five patients (32.3%) had no TR, while mild, moderate, and severe TR was found in 1537 patients (41.2%), 776 patients (20.8%), and 217 patients (5.8%), respectively. Pulmonary hypertension, significant mitral regurgitation, and atrial fibrillation/flutter were strongly associated with the development of moderate/severe of TR, while left ventricular ejection fraction <50% was inversely associated with it. Among 993 patients with moderate/severe TR, the number of patients who underwent surgical intervention for TR within 1 year was only 13 (1.3%). The median follow-up duration was 475 (interquartile range: 365-653) days with 94.0% follow-up at 1 year. As the TR severity increased, the cumulative 1 year incidence of all-cause death and HF admission proportionally increased ([14.8%, 20.3%, 23.4%, 27.0%] and [18.9%, 23.0%, 28.5%, 28.4%] in no, mild, moderate, and severe TR, respectively). Compared with no TR, the adjusted risks of patients with mild, moderate, and severe TR were significant for all-cause death (hazard ratio [95% confidence interval]: 1.20 [1.00-1.43], P = 0.0498, 1.32 [1.07-1.62], P = 0.009, and 1.35 [1.00-1.83], P = 0.049, respectively), while those were not significant for hospitalization for HF (hazard ratio [95% confidence interval]: 1.16 [0.97-1.38], P = 0.10, 1.19 [0.96-1.46], P = 0.11, and 1.20 [0.87-1.65], P = 0.27, respectively). The higher adjusted HRs of all the TR grades relative to no TR were significant for all-cause death in patients aged <80 years, but not in patients aged ≥80 years with significant interaction. CONCLUSIONS: In a large Japanese AHF population, the grades of TR could successfully stratify the risk of all-cause death. However, the association of TR with mortality was only modest and attenuated in patients aged 80 or more. Further research is warranted to evaluate how to follow up and manage TR in this elderly population.

Prognostic Value of the Severity of Clinical Congestion in Patients Hospitalized for Decompensated Heart Failure: Findings From the Japanese KCHF Registry.

BACKGROUND: Congestion is a leading cause of hospitalization and a major therapeutic target in patients with heart failure (HF). Clinical practice in Japan is characterized by a long hospital stay, which facilitates more extensive decongestion during hospitalization. We herein examined the time course and prognostic impact of clinical congestion in a large contemporary Japanese cohort of HF. METHODS AND RESULTS: Peripheral edema, jugular venous pressure, and orthopnea were graded on a standardized 4-point scale (0-3) in 3787 hospitalized patients in a Japanese cohort of HF. Composite Congestion Scores (CCS) on admission and at discharge were calculated by summing individual scores. The primary outcome was a composite of all-cause death or HF hospitalization. The median admission CCS was 4 (interquartile range, 3-6). Overall, 255 patients died during the median hospitalization length of 16 days, and 1395 died or were hospitalized for HF over a median postdischarge follow-up of 396 days. The cumulative 1-year incidence of the primary outcome increased at higher tertiles of congestion on admission (32.5%, 39.3%, and 41.0% in the mild [CCS ≤3], moderate [CCS = 4 or 5], and severe [CCS ≥6] congestion groups, respectively, log-rank P < .001). The adjusted hazard ratios of moderate and severe congestion relative to mild congestion were 1.205 (95% confidence interval [CI], 1.065-1.365; P = .003) and 1.247 (95% CI, 1.103-1.410; P < .001), respectively. Among 3445 patients discharged alive, 85% had CCS of 0 (complete decongestion) and 15% had a CCS of 1 or more (residual congestion) at discharge. Although residual congestion predicted a risk of postdischarge death or HF hospitalization (adjusted hazard ratio, 1.314 [1.145-1.509]; P < .001), the admission CCS correlated with the risk of postdischarge death or HF hospitalization, even in the complete decongestion group. No correlation was observed for postdischarge death or HF hospitalization between residual congestion at discharge and admission CCS (P for the interaction = .316). CONCLUSIONS: In total, 85% of patients were discharged with complete decongestion in Japanese clinical practice. Clinical congestion, on admission and at discharge, was of prognostic value. The severity of congestion on admission was predictive of adverse outcomes, even in the absence of residual congestion.

A comparison between hospital follow-up and collaborative follow-up in patients with acute heart failure.

AIMS: There are no previous studies focusing on collaborative follow-ups between hospitals and clinics for patients discharged after acute heart failure (AHF) in Japan. The purpose of this study was to determine the status of collaboration between hospitals and clinics for patients with AHF in Japan and to compare patient characteristics and clinical outcomes using a large Japanese observational database. METHODS AND RESULTS: Of 4056 consecutive patients hospitalized for AHF in the Kyoto Congestive Heart Failure registry, we analysed 2862 patients discharged to go home, who were divided into 1674 patients (58.5%) followed up at hospitals with index hospitalization (hospital follow-up group) and 1188 (41.5%) followed up in a collaborative fashion with clinics or other general hospitals (collaborative follow-up group). The primary outcome was a composite of all-cause death or heart failure (HF) hospitalization within 1 year after discharge. Previous hospitalization for HF and length of hospital stay longer than 15 days were associated with hospital follow-up. Conversely, ≥80 years of age, hypertension, and cognitive dysfunction were associated with collaborative follow-up. The cumulative 1-year incidence of the primary outcome, all cause death, and cardiovascular death were similar between the hospital and collaborative follow-up groups (31.6% vs. 29.6%, P = 0.51, 13.1% vs, 13.9%, P = 0.35, 8.4% vs. 8.2%, P = 0.96). Even after adjusting for confounders, the difference in risk for patients in the hospital follow-up group relative to those in the collaborative follow-up group remained insignificant for the primary outcome, all-cause death, and cardiovascular death (HR: 1.11, 95% CI: 0.97-1.27, P = 0.14, HR: 1.10, 95% CI: 0.91-1.33, P = 0.33, HR: 0.96, 95% CI: 0.87-1.05, P = 0.33). The cumulative 1-year incidence of HF hospitalization was higher in the hospital follow-up group than in the collaborative follow-up group (25.5% vs. 21.3%, P = 0.02). The risk of HF hospitalization was higher in the hospital follow-up group than in the collaborative follow-up group (HR: 1.19, 95% CI: 1.01-1.39, P = 0.04). CONCLUSIONS: In patients hospitalized for AHF, 41.5% received collaborative follow-up after discharge. The risk of HF hospitalization was higher in the hospital follow-up group than in the collaborative follow-up, although risk of the primary outcome, all-cause death, and cardiovascular death were similar between groups.

Polypharmacy and Clinical Outcomes in Hospitalized Patients With Acute Decompensated Heart Failure.

BACKGROUND: Polypharmacy is a common problem among patients with acute decompensated heart failure (ADHF) who often have multiple comorbidities. OBJECTIVE: The aim of this study was to define the number of medications at hospital discharge and whether it is associated with clinical outcomes at 1 year. METHODS: We evaluated the number of medications in 2578 patients with ADHF who were ambulatory at hospital discharge in the Kyoto Congestive Heart Failure Registry and compared 1-year outcomes in 4 groups categorized by quartiles of the number of medications (quartile 1, ≤ 5; quartile 2, 6-8; quartile 3, 9-11; and quartile 4, ≥ 12). RESULTS: At hospital discharge, the median number of medications was 8 (interquartile range, 6-11) with 81.5% and 27.8% taking more than 5 and more than 10 medications, respectively. The cumulative 1-year incidence of a composite of death or rehospitalization (primary outcome measure) increased incrementally with an increasing number of medications (quartile 1, 30.8%; quartile 2, 31.6%; quartile 3, 39.7%; quartile 4, 50.3%; P < .0001). After adjusting for confounders, the excess risks of quartile 4 relative to those of quartile 1 remained significant ( P = .01). CONCLUSIONS: In the contemporary cohort of patients with ADHF in Japan, polypharmacy at hospital discharge was common, and excessive polypharmacy was associated with a higher risk of mortality and rehospitalizations within a 1-year period. Collaborative disease management programs that include a careful review of medication lists and an appropriate deprescribing protocol should be implemented for these patients.

Insomnia in patients with acute heart failure: from the KCHF registry.

AIMS: Insomnia is a known risk factor for heart failure (HF) and a predictor of cardiac events in HF patients, but the clinical significance of insomnia in patients with acute HF (AHF) is not adequately evaluated. This study aimed to investigate the association between insomnia and subsequent clinical outcomes in patients with AHF. METHODS: From the Kyoto Congestive Heart Failure registry, consecutive 3414 patients hospitalized for HF who were discharged alive were divided into the 2 groups at discharge: insomnia group and non-insomnia group. We compared baseline characteristics and 1 year clinical outcomes according to the presence of insomnia. The primary outcome measure was all-cause death. RESULTS: There were 330 patients (9.7%) and 3084 patients (90.3%) with and without insomnia, respectively. In the multivariable logistic regression analysis, brain-type natriuretic peptide above median value at discharge (OR = 1.50, 95% CI = 1.08-2.10, P = 0.02) and the presence of oedema at discharge (OR = 4.23, 95% CI = 2.95-6.07, P < 0.001) were positively associated with insomnia at discharge, whereas diuretics at discharge (OR = 0.60, 95% CI = 0.39-0.90, P = 0.01) were negatively associated with insomnia at discharge. The cumulative 1 year incidence of all-cause death was significantly higher in the insomnia group than in the non-insomnia group (25.1% vs. 16.2%, P < 0.001). Even after adjusting the confounders, the higher mortality risk of patients with insomnia relative to those without insomnia remained significant (HR = 1.55, 95% CI = 1.24-1.94; P < 0.001). CONCLUSIONS: Patients with insomnia at discharge were associated with a higher risk of mortality than those without insomnia at discharge.

Appetite loss at discharge from acute decompensated heart failure: Observation from KCHF registry.

OBJECTIVE: The complex link between nutritional status, protein and lipid synthesis, and immunity plays an important prognostic role in patients with heart failure. However, the association between appetite loss at discharge and long-term outcome remains unclear. METHODS: The Kyoto Congestive Heart Failure registry is a prospective cohort study that enrolled consecutive patients hospitalized for acute decompensated heart failure (ADHF) in Japan. We assessed 3528 patients alive at discharge, and for whom appetite and follow-up data were available. We compared one-year clinical outcomes in patients with and without appetite loss at discharge. RESULTS: In the multivariable logistic regression analysis using 19 clinical and laboratory factors with P value < 0.1 by univariate analysis, BMI < 22 kg/m2 (odds ratio (OR): 1.57, 95% confidence interval (CI): 1.11-2.24, P = 0.01), CRP >1.0mg/dL (OR: 1.49, 95%CI: 1.04-2.14, P = 0.03), and presence of edema at discharge (OR: 4.30, 95%CI: 2.99-6.22, P<0.001) were associated with an increased risk of appetite loss at discharge, whereas ambulatory status (OR: 0.57, 95%CI: 0.39-0.83, P = 0.004) and the use of ACE-I/ARB (OR: 0.70, 95% CI: 0.50-0.98, P = 0.04) were related to a decreased risk in the presence of appetite loss. The cumulative 1-year incidence of all-cause death (primary outcome measure) was significantly higher in patients with appetite loss than in those without appetite loss (31.0% vs. 15.0%, P<0.001). The excess adjusted risk of appetite loss relative to no appetite loss remained significant for all-cause death (hazard ratio (HR): 1.63, 95%CI: 1.29-2.07, P<0.001). CONCLUSIONS: Loss of appetite at discharge was associated with worse 1-year mortality in patients with ADHF. Appetite is a simple, reliable, and useful subjective marker for risk stratification of patients with ADHF.

Public assistance in patients with acute heart failure: a report from the KCHF registry.

AIMS: There 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 RESULTS: The 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). CONCLUSIONS: The 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.

Left atrial reverse remodeling improves risk stratification in patients with heart failure with recovered ejection fraction.

We aimed to investigate the relationship between left atrial (LA) reverse remodeling and prognosis of heart failure (HF) with recovered ejection fraction (EF) (HFrecEF). Among 1,246 patients with acute heart failure enrolled in the prospective longitudinal follow-up study, 397 patients with HF with mildly-reduced EF and with reduced EF at discharge were analyzed. Echocardiography was performed during the index hospitalization and at the 6-month follow-up after discharge. They were divided into non-HFrecEF (n = 227) and HFrecEF (n = 170) groups. The primary outcome measure was a composite of all-cause death or hospitalization for HF. The cumulative 180-day incidence of the primary outcome measure after follow-up echocardiography was significantly lower in the HFrecEF group than in the non-HFrecEF group (8.9% versus 23.4%, log-rank P = 0.0002). LA reverse remodeling was associated with a lower cumulative 6-month incidence of the primary outcome measure in the HFrecEF group (4.7% versus 18.0%; HR: 0.27, 95%CI: 0.09-0.79, P = 0.01), but not in the non-HFrecEF group (24.4% versus 22.6%; HR: 1.13, 95%CI: 0.65-1.96, P = 0.28) with a significant LA reverse remodeling-by-HFrecEF interaction (P for interaction = 0.02). Combination of left ventricular and atrial reverse remodeling may help in improving HF risk stratification.

Starting Neurohormonal Antagonists in Patients With Acute Heart Failure With Mid-Range and Preserved Ejection Fraction.

BACKGROUND: The clinical benefits of neurohormonal antagonists for patients with heart failure (HF) with mid-range and preserved ejection fraction (HFmrEF and HFpEF) are uncertain.Methods and Results: This study analyzed 858 consecutive patients with HFmrEF (EF: 40-49%) or HFpEF (EF ≥50%), who were hospitalized for acute HF, and who were discharged alive, and were not taking angiotensin-converting enzyme inhibitors (ACE)-I/ angiotensin II receptor blockers (ARB) or ß-blockers at admission. The study population was classified into 4 groups according to the status of prescription of ACE-I/ARB and ß-blocker at discharge: no neurohormonal antagonist (n=342, 39.9%), ACE-I/ARB only (n=128, 14.9%), ß-blocker only (n=189, 22.0%), and both ACE-I/ARB and ß-blocker (n=199, 23.2%) groups. The primary outcome measure was a composite of all-cause death or HF hospitalization. The cumulative 1-year incidence of the primary outcome measure was 41.2% in the no neurohormonal antagonist group, 34.0% in the ACE-I/ARB only group, 28.6% in the ß-blocker only group, and 16.4% in the both ACE-I/ARB and ß-blocker group (P<0.001). Compared with the no neurohormonal antagonist group, both the ACE-I/ARB and ß-blocker groups were associated with a significantly lower risk for a composite of all-cause death or HF hospitalization (HR: 0.46, 95% CI: 0.28-0.76, P=0.002). CONCLUSIONS: In hospitalized patients with HFmrEF and HFpEF, starting both ACE-I/ARB and a ß-blocker was associated with a reduced risk of the composite of all-cause death or HF hospitalization compared with patients not starting on an ACE-I/ARB or ß-blocker.

Changes in BNP levels from discharge to 6-month visit predict subsequent outcomes in patients with acute heart failure.

BACKGROUND: This study aimed to investigate the association between changes in brain natriuretic peptide (BNP) from discharge to 6-month visit and subsequent clinical outcomes in patients with acute heart failure (AHF). METHODS: Among 1246 patients enrolled in the prospective longitudinal follow-up study nested from the Kyoto Congestive Heart Failure registry, this study population included 446 patients with available paired BNP data at discharge and 6-month index visit. This study population was classified into 3 groups by percent change in BNP from discharge to 6-month visit; the low tertile (≤-44%, N = 149), the middle tertile (>-44% and ≤22%, N = 149) and the high tertile (>22%, N = 148). FINDINGS: The cumulative 180-day incidence after the index visit of the primary outcome measure (a composite endpoint of all-cause death or hospitalization for HF) was significantly higher in the high and middle tertiles than in the low tertile (26.8% and 14.4% versus 6.9%, log-rank P<0.0001). The adjusted excess risk of the high tertile relative to the low tertile remained significant for the primary outcome measure (hazard ratio: 3.43, 95% confidence interval: 1.51-8.46, P = 0.003). CONCLUSIONS: Percent change in BNP was associated with a subsequent risk for a composite of all-cause death and hospitalization for HF after adjustment of the absolute BNP values, suggesting that observing the change in BNP levels, in addition to absolute BNP levels themselves, helps us to manage patient with HF.

Current use of inotropes according to initial blood pressure and peripheral perfusion in the treatment of congestive heart failure: findings from a multicentre observational study.

OBJECTIVES: Current guidelines restrict the use of inotropes for the treatment for heart failure (HF) unless the patients are hypotensive or hypoperfused because of safety concerns. This study sought to characterise the contemporary real-world use of inotropes and associated long-term outcomes according to systolic blood pressure (sBP) and perfusion status. DESIGN: A multicentre prospective cohort study. SETTING: This study was nested from the Kyoto Congestive Heart Failure registry, which included consecutive Japanese patients admitted for HF. PARTICIPANTS: We categorised 3995 patients into two groups: sBP ≥90 mm Hg and warm profile group, and sBP <90 mm Hg or cold profile group. In each group, patients were stratified across the use of inotropes within 24 hours of hospital presentation. PRIMARY AND SECONDARY OUTCOMES: The primary outcome was all-cause death throughout follow-up. Secondary outcomes included cardiovascular death throughout follow-up, all-cause death during index hospitalisation and after discharge, and HF hospitalisation. RESULTS: A total of 793 patients (20%) presented with sBP <90 mm Hg or cold profile, whereas 3202 patients had sBP ≥90 mm Hg and warm profile; 276 patients (35%) in the sBP <90 mm Hg/cold group and 312 patients (10%) in the sBP ≥90 mm Hg/warm group received initial inotropic treatment. Adjusted excess risk of inotrope use relative to no inotrope for the primary outcome measure was significant in the sBP ≥90 mm Hg/warm group (adjusted HR), 1.36; 95% CI 1.09 to 1.72, p=0.006) but not in the sBP <90 mm Hg/cold group (adjusted HR, 1.28, 95% CI 0.96 to 1.69, p=0.09). Risk for postdischarge all-cause death and HF hospitalisation was not significantly different between the patients with inotropes and no inotropes in both groups. CONCLUSION: Inotrope use in the absence of hypotension and hypoperfusion is still common, but associated with a worse long-term prognosis. TRIAL REGISTRATION NUMBER: UMIN000015238.

Periprocedural management and clinical outcomes of invasive procedures after venous thromboembolism: from the COMMAND VTE registry.

Anticoagulation therapy is prescribed for the prevention of recurrence in patients with venous thromboembolism, which could be temporarily interrupted during invasive procedures. The COMMAND VTE Registry is a multicenter registry enrolling 3027 consecutive patients with acute symptomatic VTE in Japan between January 2010 and August 2014. We identified patients who underwent invasive procedures during the entire follow-up period and evaluated periprocedural managements and clinical outcomes at 30 days after invasive procedures. During a median follow-up period of 1213 (IQR: 847-1764) days, 518 patients underwent invasive procedures with the cumulative incidences of 5.8% at 3 months, 11.1% at 1 year, and 24.0% at 5 years. Among 382 patients in high bleeding-risk category of invasive procedures, anticoagulation therapy had been discontinued already in 62 patients (16%) and interrupted temporarily in 288 patients (75%) during the invasive procedures with bridging anticoagulation therapy with heparin in 214 patients (56%). Among 80 patients in low bleeding-risk category, anticoagulation therapy had been already discontinued in 15 patients (19%) and interrupted temporarily in 31 patients (39%) during invasive procedure with bridging anticoagulation therapy with heparin in 17 patients (21%). At 30 days after the invasive procedures, 14 patients (2.7%) experienced recurrent VTE, while 28 patients (5.4%) had major bleeding. This study elucidated the real-world features of peri-procedural management and prognosis in patients with VTE who underwent invasive procedures during follow-up in the large multicenter VTE registry. The 30-day incidence rates of recurrent VTE and major bleeding events were 2.7% and 5.4%.

Coronary angiography in patients with acute heart failure: from the KCHF registry.

AIMS: Little 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 RESULTS: We 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 ß-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). CONCLUSIONS: In 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.

Newly Diagnosed Infection After Admission for Acute Heart Failure: From the KCHF Registry.

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.
