Background:The impact of promotional tweets from the official journal account (forCirculation JournalandCirculation Reports) on article viewership has not been thoroughly evaluated.Methods and Results:We retrospectively collected journal viewership data forCirculation JournalandCirculation Reportsfrom March 2021 to August 2021. We compared viewership between articles with (n=15) and without (n=250) tweets. After 1 : 4 propensity score matching (15 tweeted articles and 60 non-tweeted matched controls), journal viewership metrics within 7 days of the tweeting date (and the hypothetical tweeting date), was larger in tweeted articles than non-tweeted articles (median [interquartile range] Abstract page views 89 [60–104] vs. 18 [8–41]).Conclusions:This pilot study suggests a positive relationship between journal-posted promotional tweets and article viewership.

Background:Basal thinning of the interventricular septum (IVS) is an important diagnostic feature of cardiac sarcoidosis (CS), but its long-term prognostic significance remains unclear.Methods and Results:We examined 74 consecutive patients who were diagnosed with CS. Basal IVS thickness at a point located 10 mm from the aortic annulus was measured. IVS thickness at the left ventricular minor axis level (IVS) was also measured according to the recommended procedure of the American Society of Echocardiography. Patients were divided into 2 groups based on the presence or absence of basal IVS thinning, which was defined as basal IVS ≤4 mm and/or basal IVS/IVS ratio ≤0.6. Basal IVS thinning was observed in 21 patients and was associated with greater long-term adverse events during follow-up (5.1±2.5 years), although the baseline characteristics were comparable between groups (overall, P<0.01; all-cause death, P=0.53; symptomatic arrhythmias, P<0.01; heart failure admission, P=0.027). Multivariate analysis showed basal IVS thinning was an independent determinant of long-term adverse events (hazard ratio 2.86, 95% confidence interval 1.31–6.14) even after adjustment for existing prognostic variables.Conclusions:The presence of basal IVS thinning at the time of CS diagnosis was associated with poor long-term clinical outcomes, suggesting its prognostic significance in patients with CS.

Background:Ventilatory inefficiency during exercise assessed using the lowest minute ventilation/carbon dioxide production (V̇E/V̇CO2) ratio was recently proven to be a strong prognostic marker of heart failure (HF) regardless of left ventricular ejection fraction (LVEF). Its physiological background, however, has not been elucidated.Methods and Results:Fifty-seven HF patients underwent cardiopulmonary exercise testing and exercise-stress echocardiography. The lowest V̇E/V̇CO2ratio was assessed on respiratory gas analysis. Echocardiography was obtained at rest and at peak exercise. LVEF was measured using the method of disks. Cardiac output (CO) and the ratio of transmitral early filling velocity (E) to early diastolic tissue velocity (e’) were calculated using the Doppler method. HF patients were divided into preserved EF (HFpEF) and reduced EF (HFrEF) using the LVEF cut-off 40% at rest. Twenty-four patients were classified as HFpEF and 33 as HFrEF. In HFpEF, age (r=0.58), CO (r=−0.44), e’ (r=−0.48) and E/e’ (r=0.45) during exercise correlated with the lowest V̇E/V̇CO2ratio (P<0.05 for all). In contrast, in HFrEF, age (r=0.47) and CO (r=−0.54) during exercise, but not e’ and E/e’, correlated with the lowest V̇E/V̇CO2ratio.Conclusions:Loss of CO augmentation was associated with ventilatory inefficiency in HF regardless of LVEF, although lung congestion determined ventilatory efficiency only in HFpEF.

To assess myocardial fibrosis associated with muscular dystrophy, T1-mapping and extracellular volume fraction (ECV) quantification was prospectively performed using cardiovascular MR (CMR) imaging in 6 male patients with muscular dystrophy and 5 female putative carriers of Duchenne or Becker muscular dystrophy. Five patients and all putative carriers had an elevated ECV (>29.5% for men and >35.2% for women), suggesting that ECV has a potential to detect diffuse fibrotic changes in patients and putative carriers of muscular dystrophy.

Background: The ideal mortality prediction model (MPM) for acute heart failure (AHF) patients would have sufficient and stable predictive ability for long-term as well as short-term mortality. However, published MPMs for AHF predominantly predict short-term mortality up to 90 days, and their prognostic performance for long-term mortality remains unclear. Methods and Results: We analyzed 609 AHF patients in a prospective registry from January 2013 to May 2016. We compared the prognostic performance for long-term mortality among 8 systematically identified MPMs for AHF that predict short-term mortality up to 90 days from admission. The PROTECT 7-day model showed the highest c-index for long-term as well as short-term mortality among the studied MPMs. Sensitivity analyses revealed serum albumin and total cholesterol to be the most important variables, as dropping these variables resulted in a significant decline in c-index, when compared with other variables specific to the PROTECT 7-day model. Furthermore, significant improvements in c-index and net reclassification were observed when serum albumin or serum albumin plus total cholesterol was added to the studied MPMs, other than the PROTECT 7-day model. Conclusions: The PROTECT 7-day model demonstrated the highest predictive performance for long-term as well as short-term mortality in AHF patients among the published MPMs. Our findings indicate the importance of accounting for nutritional status such as serum albumin and total cholesterol in AHF patients when developing a MPM.

Background:Atrial fibrillation (AF) is an important prognostic determinant in heart failure (HF) with preserved ejection fraction (HFpEF). However, it is unclear which HFpEF phenotypes are affected by AF in terms of long-term clinical outcomes because HFpEF is a heterogeneous syndrome with comorbidities such as coronary artery disease (CAD). In this study we determined the differential prognostic significance of AF in HFpEF patients according to CAD status.Methods and Results:Data for 408 hospitalized HFpEF patients enrolled in the Japanese Heart Failure Syndrome with Preserved Ejection Fraction Nationwide Multicenter Registry were analyzed. Patients were divided into 4 groups according to the presence of AF and CAD. The primary outcome was the composite of all-cause death and HF rehospitalization. The incidence of adverse events was higher in the AF–non-CAD than non-AF–non-CAD group (P=0.004). On multivariable Cox regression analysis with prespecified confounders, AF–non-CAD was significantly associated with an increased risk of adverse events than non-AF–non-CAD (adjusted HR, 1.91; 95% CI: 1.02–3.92) regardless of the type of AF. In contrast, risk was comparable between the AF–CAD and non-AF–CAD groups (adjusted HR, 1.24; 95% CI: 0.64–2.47).Conclusions:In HFpEF patients without CAD, AF was independently related to adverse events, indicating that intensive management of AF would have more beneficial effects particularly in HFpEF patients without CAD.

Background:The vasopressin type-2 receptor antagonist tolvaptan is an essential tool in the management of decompensated heart failure (HF) in the inpatient setting for short-term use with careful monitoring. There is conflicting evidence, however, for its long-term use.Methods and Results:In this prospective, multi-center, open-labeled, randomized control trial, Assessment of QUAlity of life during long-term treatment of ToLVaptan in refractory HF (AQUA-TLV study), patients with congestive HF refractory to furosemide ≥60 mg/day were randomly assigned to a control group or tolvaptan add-on group and followed for 6 months, after confirmation of baseline urine osmolality ≥350 mOsm/L. Twenty-nine patients (median age, 60 years; 22 male) were enrolled and assigned to a control group (n=16) or a tolvaptan group (n=13). Minnesota Living with Heart Failure Questionnaire score improved significantly in the tolvaptan group (from 58 to 10, P=0.030). In the tolvaptan group, diuretics dose reduced (P=0.001), serum creatinine decreased (P=0.040), and hyponatremia tended to improve (P=0.12). The tolvaptan group had a lower HF readmission rate compared with the control group (0.213 vs. 1.242 events/year, P=0.13).Conclusions:Six-month tolvaptan therapy improved quality of life and renal function and reduced HF readmissions, when given to the estimated responders (UMIN Clinical Trial Registry Number: UMIN 000009604).

Background:Palliative care is highly relevant for patients with heart failure (HF), and there is a need for quantitative information on quality of care. Accordingly, this study aimed to develop a set of quality indicators (QIs) for palliative care of HF patients, and to conduct a practical pilot measurement of the proposed QIs in clinical practice.Methods and Results:We used a modified Delphi technique, a consensus method that involves a comprehensive literature review, face-to-face multidisciplinary panel meeting, and anonymous rating in 2 rounds. A 15-member multidisciplinary expert panel individually rated each potential indicator on a scale of 1 (lowest) to 9 (highest) for appropriateness. All indicators receiving a median score ≥7 without significant disagreement were included in the final set of QIs. Through the consensus-building process, 35 QIs were proposed for palliative care in HF patients. Practical measurement in HF patients (n=131) from 3 teaching hospitals revealed that all of the proposed QIs could be obtained retrospectively from medical records, and the following QIs had low performance (<10%): “Intervention by multidisciplinary team”, “Opioid therapy for patients with refractory dyspnea”, and “Screening for psychological symptoms”.Conclusions:The first set of QIs for palliative care of HF patients was developed and could clarify quantitative information and might improve the quality of care.
