Concomitant Mitral Regurgitation in Severe Aortic Stenosis　- Insights From the CURRENT AS Registry-2.

BACKGROUND: Data on concomitant mitral regurgitation (MR) in patients with severe aortic stenosis (AS) are scarce.Methods and Results: We investigated the risk of concomitant MR in patients with severe AS in the CURRENT AS Registry-2 according to initial treatment strategy (transcatheter aortic valve implantation [TAVI], surgical aortic valve replacement [SAVR], or conservative). Among 3,365 patients with severe AS, 384 (11.4%) had moderate/severe MR (TAVI: n=126/1,148; SAVR: n=68/591; conservative: n=190/1,626). The cumulative 3-year incidence for death or heart failure (HF) hospitalization was significantly higher in the moderate/severe than no/mild MR group in the entire population (54.6% vs. 34.3%, respectively; P<0.001) and for each treatment strategy (TAVI: 45.0% vs. 31.8% [P=0.006]; SAVR: 31.9% vs. 18.7% [P<0.001]; conservative: 67.8% vs. 41.6% [P<0.001]). The higher adjusted risk of moderate/severe MR relative to no/mild MR for death or HF hospitalization was not significant in the entire population (hazard ratio [HR] 1.15; 95% confidence interval [CI] 0.95-1.39; P=0.15); however, the risk was significant in the SAVR (HR 1.92; 95% CI 1.04-3.56; P=0.04) and conservative (HR 1.30; 95% CI 1.02-1.67; P=0.04) groups, but not in the TAVI group (HR 1.03; 95% CI 0.70-1.52; P=0.86), despite no significant interaction (Pinteraction=0.37). CONCLUSIONS: Moderate/severe MR was associated with a higher risk for death or HF hospitalization in the initial SAVR and conservative strategies, while the association was less pronounced in the initial TAVI strategy.

Rationale and study design of the GOREISAN for heart failure (GOREISAN-HF) trial: A randomized clinical trial.

BACKGROUND: The decongestion strategy using loop diuretics is essential for improving signs and symptoms of heart failure (HF). However, chronic use of loop diuretics in HF has been linked to worsening renal function and adverse clinical outcomes in a dose-dependent manner. Goreisan, a traditional Japanese herbal medicine, has a long history of use in Japan for regulating body fluid homeostasis and has been recognized as causing less adverse outcomes such as dehydration in contrast to loop diuretics in clinical practice. Therefore, we designed the GOREISAN-HF trial to evaluate the long-term effects of a new decongestion strategy adding Goreisan to usual care in patients with HF and volume overload. METHODS: The GOREISAN-HF trial is an investigator-initiated, multicenter, pragmatic, randomized, comparative effectiveness trial in which we will enroll 2,192 patients hospitalized for HF at 68 hospitals in Japan. All study participants will be randomly assigned to either a decongestion strategy that adds Goreisan at a dose of 7.5 g daily on top of usual care or usual care alone. Investigators have the flexibility to change the existing diuretic regimen in both groups. The primary end point is the improvement rate of cardiac edema at 12-month follow-up, and the co-primary end point is a composite of all-cause death or hospitalization up to the end of the planned follow-up period. Secondary end points include longitudinal changes in patient-reported outcomes, loop diuretics dose, and renal function. CONCLUSIONS: The GOREISAN-HF is the first large-scale randomized pragmatic trial to assess the efficacy and safety of a new congestion control strategy adding Goreisan to usual care in patients with HF and volume overload. REGISTRATION NUMBER: NCT04691700.

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.

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.

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.

Rationale, Design, and Baseline Characteristics of the CURRENT AS Registry-2.

BACKGROUND: There is scarce data evaluating the current practice pattern and clinical outcomes for patients with severe aortic stenosis (AS), including both those who underwent surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) and those who were managed conservatively in the TAVI era.Methods and Results: The Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis (CURRENT AS) Registry-2 is a prospective, physician-initiated, multicenter registry enrolling consecutive patients who were diagnosed with severe AS between April 2018 and December 2020 among 21 centers in Japan. The rationale for the prospective enrollment was to standardize the assessment of symptomatic status, echocardiographic evaluation, and other recommended diagnostic examinations such as computed tomography and measurement of B-type natriuretic peptide. Moreover, the schedule of clinical and echocardiographic follow up was prospectively defined and strongly recommended for patients who were managed conservatively. The entire study population consisted of 3,394 patients (mean age: 81.6 years and women: 60%). Etiology of AS was degenerative in 90% of patients. AS-related symptoms were present in 60% of patients; these were most often heart failure symptoms. The prevalence of high- and low-gradient AS was 58% and 42%, respectively, with classical and paradoxical low-flow low-gradient AS in 4.6% and 6.7%, respectively. CONCLUSIONS: The CURRENT AS Registry-2 might be large and meticulous enough to determine the appropriate timing of intervention for patients with severe AS in contemporary clinical practice.

Prognostic Implications of Reductions in Heart Rates in Patients With Acute Heart Failure and Atrial Fibrillation.

BACKGROUND: Atrial fibrillation (AF) is a common arrhythmia in patients with acute heart failure (AHF). Heart rate (HR) also changes significantly over time. However, the association between changes in HR in AF patients and prognosis is uncertain.Methods and Results:We investigated the association between HR reduction in AF achieved within 48 h of admission and 60-day mortality in patients with AHF from the REALITY-AHF study. The percentage HR (%HR) reduction was calculated as (baseline HR-HR at 48 h) / baseline HR × 100. The primary endpoint was 60-day all-cause mortality. In 468 patients with confirmed AF at both admission and 48 h after admission, the median HR at these time points was 105±31 and 84±18 beats/min, respectively. The median %HR reduction was 15.4% (interquartile range 2.2-31.4%). During the 60 days of admission, 39 deaths (8.3%) were recorded, and the %HR reduction within 48 h was significantly associated with 60-day mortality in the unadjusted model (hazard ratio [HR] 0.85; 95% confidence interval [CI] 0.77-0.95; P=0.005) and after adjusting for other covariates (HR 0.81; 95% CI 0.68-0.96; P=0.016).Furthermore, the %HR reduction was associated with a significant reduction in 60-day mortality in patients with higher baseline HR. CONCLUSIONS: %HR reduction is associated with a better short-term prognosis in patients with AHF presenting with AF, particularly in those with a rapid ventricular response.

Long-Term Impact of Diabetes Mellitus on Initially Conservatively Managed Patients With Severe Aortic Stenosis.

BACKGROUND: Although diabetes mellitus (DM) is a common comorbidity of aortic stenosis (AS), clinical evidence about the long-term effect of DM on patients with AS is insufficient.Methods and Results:Data were acquired from CURRENT AS, a large Japanese multicenter registry that enrolled 3,815 patients with severe AS. Patients without initial valve replacement were defined as the conservative group; among them, 621 (23.4%) had DM, whereas 1997 did not. The DM group was further divided into 2 groups according to insulin treatment (insulin-treated DM, n=130; non-insulin treated DM, n=491). The primary outcome was a composite of aortic valve (AV)-related death and heart failure (HF) hospitalization. Secondary outcomes were AV-related death, HF hospitalization, all-cause death, cardiovascular death, sudden death, and surgical or transcatheter AV replacement during follow up. As a result, DM was associated with higher risk for the primary outcome (52.8% vs. 42.9%, P<0.001), with a statistically significant adjusted hazard ratio (HR 1.33, 95% confidence interval: 1.14-1.56, P<0.001). All secondary outcomes were not significantly different between DM and non-DM patients after adjusting for confounding factors, except for HF hospitalization. Insulin use was not associated with higher incidence of primary or secondary outcome. CONCLUSIONS: In initially conservatively managed patients with AS, DM was independently associated with higher risk for a composite of AV-related death or HF hospitalization; however, insulin use was not associated with poor outcomes.

Age-Related Differences in the Effects of Initial Aortic Valve Replacement vs. Conservative Strategy on Long-Term Outcomes in Asymptomatic Patients With Severe Aortic Stenosis.

BACKGROUND: This study aimed to evaluate the effect of the initial aortic valve replacement (AVR) strategy relative to a conservative strategy on long-term outcomes stratified by age among asymptomatic patients with severe aortic stenosis (AS).Methods and Results:Among 1,808 asymptomatic severe AS patients in the CURRENT AS registry, there were 1,166 patients aged ≥75 years (initial AVR: n=124, and conservative: n=1,042), and 642 patients with age <75 years (initial AVR: n=167, and conservative: n=475). Median follow-up interval was 1,280 (interquartile range [IQR]: 1,012-1,611) days, and 1461 (IQR: 1,132-1,886) days in patients aged ≥ and <75 years, respectively. The favorable effect of the initial AVR strategy relative to conservative strategy for heart failure (HF) hospitalization was seen regardless of the age stratum (≥75 years: adjusted hazard ratio [HR] 0.13, 95% confidence interval [CI] 0.05-0.34, and <75 years: HR 0.37, 95% CI 0.14-0.99, interaction P=0.35). However, the lower mortality risk of the initial AVR strategy relative to conservative strategy was significant in patients aged ≥75 years, but not in patients <75 years, with significant interaction (HR 0.35, 95% CI 0.20-0.61, and HR 0.69, 95% CI 0.41-1.16, interaction P=0.016). CONCLUSIONS: The benefit of initial AVR in reducing HF hospitalization in asymptomatic patients with severe AS was consistently seen regardless of age. The magnitude of mortality benefit of initial AVR was greater in super-elder patients than in non-super-elder patients.

Transcatheter Aortic Valve Implantation vs. Surgical Aortic Valve Replacement for Severe Aortic Stenosis in Real-World Clinical Practice.

BACKGROUND: There are no data comparing transcatheter aortic valve implantation (TAVI) with surgical aortic valve replacement (SAVR) outcomes in real clinical practice in Japan. METHODS AND RESULTS: We combined 2 independent registries, the K-TAVI Registry (a 6-center prospective registry of consecutive patients who underwent TAVI) and the CURRENT AS Registry (a large, 27-center registry of 3,815 consecutive patients with severe aortic stenosis [AS]). In the K-TAVI Registry, 338 patients underwent TAVI with SAPIEN XT balloon-expandable valves from October 2013 to January 2016, whereas in the CURRENT AS Registry 237 patients with severe AS underwent SAVR from January 2003 to December 2011. Propensity score matching was conducted, with final cohort comprising 306 patients. The cumulative 2-year incidence of all-cause death and heart failure (HF) hospitalization did not differ significantly between the TAVI and SAVR groups (13.7% vs. 12.4% [P=0.81] and 7.9% vs 3.9% [P=0.13], respectively). After adjusting for residual confounders, there were no significant differences between the TAVI and SAVR groups in the risk for all-cause death (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.35-1.58; P=0.43) or HF hospitalization (HR 1.27; 95% CI 0.40-4.59; P=0.69). CONCLUSIONS: These findings from 2 independent Japanese registries suggest that the 2-year risk of all-cause mortality and HF does not differ significantly between TAVI and SAVR groups in real-world practice in Japan.

Clinical and Prognostic Values of ALBI Score in Patients With Acute Heart Failure.

BACKGROUND: Although liver dysfunction is one of the common complications in patients with acute heart failure (AHF), no integrated marker has been defined. The albumin-bilirubin (ALBI) score has recently been proposed as a novel, clinically-applicable scoring system for liver dysfunction. We investigated the utility of the ALBI score in patients with AHF compared to that for a preexisting liver dysfunction score, the Model of End-Stage Liver Disease Excluding prothrombin time (MELD XI) score. METHODS: We evaluated ALBI and MELD XI scores in 1,190 AHF patients enrolled in the prospective, multicentre Registry Focused on Very Early Presentation and Treatment in Emergency Department of Acute Heart Failure study. The associations between the two scores and the clinical profile and prognostic predictive ability for 1-year mortality were evaluated. RESULTS: The mean MELD XI and ALBI scores were 13.4±4.8 and -2.25±0.48, respectively. A higher ALBI score, but not higher MELD XI score, was associated with findings of fluid overload. After adjusting for pre-existing prognostic factors, the ALBI score (HR 2.11, 95% CI: 1.60-2.79, p<0.001), but not the MELD XI score (HR 1.02, 95% CI: 0.99-1.06, p=0.242), was associated with 1-year mortality. Likewise, area under the receiver-operator-characteristic curves for 1-year mortality significantly increased when the ALBI score (0.71 vs. 0.74, p=0.020), but not the MELD XI score (0.71 vs. 0.72, p=0.448), was added to the pre-existing risk factors. CONCLUSIONS: The ALBI score is potentially a suitable liver dysfunction marker that incorporates information on fluid overload and prognosis in patients with AHF. These results provide new insights into heart-liver interactions in AHF patients.

Prognostic Value of BNP Reduction During Hospitalization in Patients With Acute Heart Failure.

BACKGROUND: Prognostication of patients discharged after acute heart failure (AHF) hospitalization remains challenging. Body weight (BW) reduction is often used as a surrogate marker of decongestion despite the paucity of evidence. We thought to test the hypothesis that B-type natriuretic peptide (BNP) reduction during hospitalization has independent prognostic value in AHF. METHODS AND RESULTS: We studied the prognostic predictability of percentage BNP reduction achieved during hospitalization in patients from the REALITY-AHF study. Percentage BNP reduction was defined as (BNP on admission - BNP at discharge) / BNP on admission × 100. The primary endpoint was 1-year all-cause death. In 1028 patients (age, 77 ± 13 years; 57% male; left ventricular ejection fraction, 47 ± 16%) with AHF, median BNP level at admission was 747 ng/L (interquartile range, 439-1367 ng/L) and median percentage BNP reduction was 62.5% (interquartile range, 36.5-78.5%). The smallest percentage BNP reduction quartile had more than 2-fold higher risk of all-cause death than the greatest quartile (23.0% vs 9.7%, P< .001). After adjusting for covariates including BNP at discharge, the percentage BNP reduction was significantly associated with all-cause death (hazard ratio 0.96, 95% confidence interval 0.93-0.99, P= .032), whereas percentage BW reduction was not. Percentage BNP reduction was more predictive in patients with heart failure with reduced ejection fraction than in those with preserved ejection fraction. CONCLUSIONS: The prognostic value of percentage BNP reduction during hospitalization was superior to that of percentage BW reduction and was independent of other risk markers, including BNP at discharge.

Reasons for Choosing Conservative Management in Symptomatic Patients With Severe Aortic Stenosis　- Observations From the CURRENT AS Registry.

BACKGROUND: There has not been a previous report on the long-term outcomes of those patients who refuse aortic valve replacement (AVR) despite physicians' recommendations.Methods and Results:Among 3,815 consecutive patients with severe aortic stenosis (AS) enrolled in the CURRENT AS registry, the study population comprised 2,005 symptomatic patients, who were subdivided into 3 groups by their treatment strategy and the reasons for conservative strategy (Initial AVR group: n=905; Patient rejection group: n=256; Physician judgment group, n=844). The primary outcome measure was a composite of aortic valve-related death and heart failure hospitalization. Patients in the patient rejection group as compared with those in the physician judgment group were younger, and had less comorbidities, and lower surgical risk scores. The cumulative 5-year incidence of the primary outcome measure in the patient rejection group was markedly higher than that in the initial AVR group, and was similar to that in the physician judgment group (60.7%, 19.0%, and 66.4%, respectively). CONCLUSIONS: Patient rejection was the reason for non-referral to AVR in nearly one-quarter of the symptomatic patients with severe AS who were managed conservatively. The dismal outcome in patients who refused AVR was similar to that in patients who were not referred to AVR based on physician judgment despite less comorbidities and lower surgical risk scores in the former than in the latter.

Specialty-Related Differences in the Acute-Phase Treatment and Prognosis in Patients With Acute Heart Failure　- Insights From REALITY-AHF.

BACKGROUND: The aim of this study was to assess specialty-related differences in the treatment for patients with acute heart failure (AHF) in the acute phase and subsequent prognostic differences. Methods and Results: We analyzed hospitalizations for AHF in REALITY-AHF, a multicenter prospective registry focused on very early presentation and treatment in patients with AHF. All patients were classified according to the medical specialty of the physicians responsible for contributed most to decisions regarding the initial diagnosis and treatment after the emergency department (ED) arrival. Patients initially managed by emergency physicians (n=614) or cardiologists (n=911) were analyzed. After propensity-score matching, vasodilators were used less often by emergency physicians than by cardiologists at 90 min after ED arrival (29.8% vs. 46.1%, P<0.001); this difference was also observed at 6, 24, and 48 h. Cardiologists administered furosemide earlier than emergency physicians (67 vs. 102 min, P<0.001). However, the use of inotropes, noninvasive ventilation, and endotracheal intubation were similar between groups. In-hospital mortality did not differ between patients managed by emergency physicians and those managed by cardiologists (4.1% vs. 3.8%, odds ratio 1.12; 95% confidence interval 0.58-2.14). CONCLUSIONS: Despite differences in initial management, no prognostic difference was observed between emergency physicians and cardiologists who performed the initial management of patients with AHF.

Demographics, Management, and In-Hospital Outcome of Hospitalized Acute Heart Failure Syndrome Patients in Contemporary Real Clinical Practice in Japan　- Observations From the Prospective, Multicenter Kyoto Congestive Heart Failure (KCHF) Registry.

BACKGROUND: There is a scarcity of reports on the clinical characteristics and management practice in contemporary all-comer patients with acute decompensated heart failure (ADHF). Methods and Results: The Kyoto Congestive Heart Failure (KCHF) registry is a prospective observational cohort study enrolling 4,056 consecutive patients who had hospital admission due to ADHF without any exclusion criteria between October 2014 and March 2016 in the 19 participating hospitals in Japan. Baseline characteristics, clinical presentations, management, and in-hospital outcomes were compared between heart failure (HF) with reduced left ventricular ejection fraction (LVEF; HFrEF, LVEF <40%), HF with mid-range LVEF (HFmrEF, LVEF 40-49%), and HF with preserved LVEF (HFpEF, LVEF ≥50%). Of the 4,041 patients with documented LVEF, 1,744 (43%) had HFpEF; 746 (19%), HFmrEF; and 1,551 (38%), HFrEF. The median age was 80 years (IQR, 72-86 years) in the entire population, and was higher with increasing LVEF (P<0.001). The in-hospital mortality rate was higher in the HFrEF than in the HFmrEF and HFpEF groups (9.2%, 4.8%, and 5.1%, respectively, P<0.001). CONCLUSIONS: This registry elucidated the clinical features and clinically relevant in-hospital outcomes in contemporary consecutive patients with ADHF in real-world clinical practice in Japan. When classified by LVEF, significant differences in characteristics and in-hospital outcomes existed between patients with HFrEF, HFmrEF, and HFpEF.

Acute Heart Failure in Patients With Severe Aortic Stenosis　- Insights From the CURRENT AS Registry.

BACKGROUND: Clinical profiles of acute heart failure (AHF) complicating severe aortic stenosis (AS) remain unclear.Methods and Results:From a Japanese multicenter registry enrolling consecutive patients with severe AS, 3,813 patients were categorized into the 3 groups according to the symptom of heart failure (HF); No HF (n=2,210), chronic HF (CHF) (n=813) and AHF defined as hospitalized HF at enrolment (n=790). Median follow-up was 1,123 days with 93% follow-up rate at 2 years. Risk factors for developing AHF included age, female sex, lower body mass index, untreated coronary artery stenosis, anemia, history of HF, left ventricular ejection fraction <50%, presence of any combined valvular disease, peak aortic jet velocity ≥5 m/s and tricuspid regurgitation pressure gradient ≥40 mmHg, and negative risk factors included dyslipidemia, history of percutaneous coronary intervention and hemodialysis. Respective cumulative 5-year incidences of all-cause death and HF hospitalization in No HF, CHF and AHF groups were 37.1%, 41.8% and 61.8% (P<0.001) and 20.7%, 33.8% and 52.3% (P<0.001). Even in the initial aortic valve replacement (AVR) stratum, AHF was associated with excess 5-year mortality risk relative to No HF and CHF (adjusted hazard ratio [HR] 1.64; 95% confidence interval [CI]: 1.14-2.36, P=0.008; adjusted HR 1.47; 95% CI: 1.03-2.11, P=0.03, respectively). CONCLUSIONS: AHF complicating severe AS was associated with an extremely dismal prognosis, which could not be fully resolved by AVR. Careful management to avoid the development of AHF is crucial.

Sex Differences in Severe Aortic Stenosis　- Clinical Presentation and Mortality.

BACKGROUND: There is a paucity of data on the sex differences in the prevalence, clinical presentation, and prognosis of aortic stenosis (AS).Methods and Results:A total of 3,815 consecutive patients with severe AS were enrolled in the multicenter CURRENT AS registry between January 2003 and December 2011. The registry included 1,443 men (38%) and 2,372 women (62%). Women were much older than men (79±10 vs. 75±10 years, P<0.0001), and the ratio of women to men increased with age. The cumulative 5-year incidence of all-cause death was significantly higher in men than in women (47% vs. 41%, P=0.003), although women were more symptomatic and much older. The 5-year mortality was similar between men and women at age <65 years (16% vs. 15%, P=0.99), whereas it was significantly higher in men than in women at age ≥65 years (65-74 years, 38% vs. 19%, P<0.0001; 75-84 years, 55% vs. 34%, P<0.0001; ≥85 years: 82% vs. 72%, P=0.03). CONCLUSIONS: A large Japanese multicenter registry of consecutive patients with severe AS included a much higher proportion of women than men, with the female:male sex ratio increasing with age. The 5-year mortality rate of women was lower than that of men. Lower 5-year mortality rates in women were consistently seen across all age groups >65 years.

Effectiveness and safety of morphine administration for refractory dyspnoea among hospitalised patients with advanced heart failure: the Morphine-HF study.

OBJECTIVES: Morphine is effective in alleviating dyspnoea in patients with cancer. We aimed to investigate the effectiveness and safety of morphine administration for refractory dyspnoea in patients with advanced heart failure (HF). METHODS: We conducted a multicentre, prospective, observational study of hospitalised patients with advanced HF in whom morphine was administered for refractory dyspnoea. Morphine effectiveness was evaluated by dyspnoea intensity changes, assessed regularly by both a quantitative subjective scale (Visual Analogue Scale (VAS; graded from 0 to 100 mm)) and an objective scale (Support Team Assessment Schedule-Japanese (STAS-J; graded from 0 to 4 points)). Safety was assessed by vital sign changes and new-onset severe adverse events, including nausea, vomiting, constipation and delirium based on the Common Terminology Criteria for Adverse Events. RESULTS: From 15 Japanese institutions between September 2020 and August 2022, we included 28 hospitalised patients with advanced HF in whom morphine was administered (mean age: 83.8±8.7 years, male: 15 (54%), New York Heart Association class IV: 26 (93%) and mean left ventricular ejection fraction: 38%±19%). Both VAS and STAS-J significantly improved from baseline to day 1 (VAS: 67±26 to 50±31 mm; p=0.02 and STAS-J: 3.3±0.8 to 2.6±1.1 points; p=0.006, respectively), and thereafter the improvements sustained through to day 7. After morphine administration, vital signs including blood pressure, pulse rate and oxygen saturation did not change, and no new-onset severe adverse events occurred through to day 7. CONCLUSIONS: This study suggested acceptable effectiveness and safety for morphine administration in treating refractory dyspnoea in hospitalised patients with advanced HF.
