Background: How patient characteristics and outcomes vary according to the duration of heart failure (HF) is unknown in individuals with mildly reduced or preserved ejection fraction. We compared these, and the efficacy and safety of dapagliflozin, according to the time from diagnosis of HF in a prespecified analysis of the DELIVER trial (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure). Methods: HF duration was categorized as ≤6 months, >6 to 12 months, >1 to 2 years, >2 to 5 years, or >5 years. The primary outcome was the composite of worsening HF or cardiovascular death. The effect of treatment was examined by HF duration category. Results: The number of patients in each category was as follows: 1160 (≤6 months), 842 (>6 to 12 months), 995 (>1 to 2 years), 1569 (>2 to 5 years), and 1692 (>5 years). Patients with longer-duration HF were older and had more comorbidities with worse symptoms. The rate of the primary outcome (per 100 person-years) increased with HF duration: ≤6 months, 7.3 (95% CI, 6.3 to 8.4); >6 to 12 months, 7.1 (6.0 to 8.5); >1 to 2 years, 8.4 (7.2 to 9.7); >2 to 5 years, 8.9 (7.9 to 9.9); and >5 years, 10.6 (9.5 to 11.7). Similar trends were seen for other outcomes. The benefit of dapagliflozin was consistent across HF duration category: the hazard ratio for the primary outcome in the ≤6-month group was 0.67 (95% CI, 0.50 to 0.91); >6 to 12 months, 0.78 (0.55 to 1.12); >1 to 2 years, 0.81 (0.60 to 1.09); >2 to 5 years, 0.97 (0.77 to 1.22); and >5 years, 0.78 (0.64 to 0.96; P interaction =0.41). The absolute benefit was greatest in longest-duration HF; the number needed to treat for HF >5 years was 24 versus 32 for ≤6 months. Conclusions: Patients with longer-duration HF were older, had more comorbidities and symptoms, and had higher rates of worsening HF and death. The benefits of dapagliflozin were consistent across HF duration. Even patients with long-standing HF and generally mild symptoms are not stable, and it is not too late for such patients to benefit from a sodium–glucose cotransporter 2 inhibitor.

AimsFew reports have examined the incidence of ventricular tachycardia (VT) and ventricular fibrillation (VF) or their relationship with mortality in patients with heart failure with mildly reduced ejection fraction (HFmrEF) or heart failure with preserved ejection fraction (HFpEF).Methods and resultsData from the PARAGON-HF, TOPCAT, I-Preserve, and CHARM-Preserved trials were merged. VT/VF, reported as adverse events, were identified. Patients who experienced VT/VF were compared with patients who did not. The relationship between VT/VF and mortality was examined in time-updated Cox proportional hazard regression models. Variables associated with VT/VF were examined in Cox proportional hazard regression models. The rate of VT/VF in patients with HFmrEF compared with patients with HFpEF was examined in a Cox proportional hazards regression model. Of 13 609 patients, over a median follow-up of 1170 days (interquartile range: 966–1451), 146 (1.1%) experienced an investigator-reported VT/VF (incidence rate 0.3 per 100 person-years). Patients who experienced VT/VF were more likely to be male, have had a myocardial infarction, poorer renal function, more adverse left ventricular remodelling, and higher N-terminal pro-B-type natriuretic peptide (NT-proBNP) than patients who did not. Occurrence of VT/VF was associated with NT-proBNP, history of atrial fibrillation/flutter, male sex, lower ejection fraction, and history of hypertension. VT/VF was associated with all-cause death [adjusted hazard ratio (HR): 3.95, 95% confidence interval (CI): 2.80–5.57; P < 0.001] and cardiovascular death, driven by death from heart failure and not sudden death. Patients with HFmrEF had a higher rate of VT/VF than patients with HFpEF (adjusted HR: 2.19, 95% CI: 1.77–2.71).ConclusionVT/VF was uncommon in patients with HFmrEF and HFpEF. However, such events were strongly associated with mortality and appear to be a marker of disease severity rather than risk of sudden death.Clinical trial registrationClinicalTrials.gov unique identifier: NCT01920711(PARAGON-HF); NCT00094302 (TOPCAT); NCT00095238 (I-Preserve); NCT00634712 (CHARM-Preserved)

Background: Atrial fibrillation (AF) is common in heart failure (HF), is associated with worse outcomes compared with sinus rhythm, and may modify the effects of therapy.Objectives: This study examined the effects of dapagliflozin according to the presence or not of AF in the DELIVER (Dapagliflozin Evaluation to Improve the LIVEs of Patients With PReserved Ejection Fraction Heart Failure) trial.Methods: A total of 6,263 patients with HF with New York Heart Association functional class II-IV, left ventricular ejection fraction >40%, evidence of structural heart disease, and elevated N-terminal pro–B-type natriuretic peptide levels were randomized to dapagliflozin or placebo. Clinical outcomes and the effect of dapagliflozin, according to AF status, were examined. The primary outcome was a composite of cardiovascular death or worsening HF.Results: Of the 6,261 patients with data on baseline AF, 43.3% had no AF, 18.0% had paroxysmal AF, and 38.7% had persistent/permanent AF. The risk of the primary endpoint was higher in patients with AF, especially paroxysmal AF, driven by a higher rate of HF hospitalization: no AF, HF hospitalization rate per 100 person-years (4.5 [95% CI: 4.0-5.1]), paroxysmal AF (7.5 [95% CI: 6.4-8.7]), and persistent/permanent AF (6.4 [95% CI: 5.7-7.1]) (P < 0.001). The benefit of dapagliflozin on the primary outcome was consistent across AF types: no AF, HR: 0.89 (95% CI: 0.74-1.08); paroxysmal AF, HR: 0.75 (95% CI: 0.58-0.97); persistent/permanent AF, HR: 0.79 (95% CI: 0.66-0.95) (Pinteraction = 0.49). Consistent effects were observed for HF hospitalization, cardiovascular death, all-cause mortality, and improvement in the KCCQ-TSS.Conclusions: In DELIVER, the beneficial effects of dapagliflozin compared with placebo on clinical events and symptoms were consistent, irrespective of type of AF at baseline.

Aims To examine the effects of a 24-month treatment with ipragliflozin on carotid intima-media thickness (IMT) in type 2 diabetes patients. Methods and results In this multicenter, prospective, randomized, open-label, and blinded-endpoint investigator-initiated clinical trial, adults with type 2 diabetes and haemoglobin A1C (HbA1c) of 6.0–10.0% (42–86 mmol/mol) were randomized equally to ipragliflozin (50 mg daily) and non-sodium-glucose cotransporter-2 (SGLT2) inhibitor use of standard-care (control group) for type 2 diabetes and were followed-up to 24 months. The primary endpoint was the change in mean common carotid artery IMT (CCA-IMT) from baseline to 24 months. A total of 482 patients were equally allocated to the ipragliflozin (N = 241) and control (N = 241) groups, and 464 patients (median age 68 years, female 31.7%, median type 2 diabetes duration 8 years, median HbA1c 7.3%) were included in the analyses. For the primary endpoint, the changes in the mean CCA-IMT from baseline to 24 months were 0.0013 [95% confidence interval (CI), −0.0155–0.0182] mm and 0.0015 (95% CI, −0.0155–0.0184) mm in the ipragliflozin and control groups, respectively, with an estimated group difference (ipragliflozin-control) of −0.0001 mm (95% CI, −0.0191–0.0189; P = 0.989). A group difference in HbA1c change at 24 months was also non-significant between the treatment groups [−0.1% (95% CI, −0.2–0.1); P = 0.359]. Conclusion Twenty-four months of ipragliflozin treatment did not affect carotid IMT status in patients with type 2 diabetes recruited in the PROTECT study, relative to the non-SGLT2 inhibitor-use standard care for type 2 diabetes.

Case Report ,Cardiology and Cardiovascular Medicine - Abstract
A 42-year-old man with a history of acute myocarditis after streptococcal pharyngitis developed recurrent fulminant myocarditis. Endomyocardial biopsy revealed myocyte degeneration, interstitial edema, and neutrophil infiltration. The patient's cardiac function deteriorated rapidly, and he died despite mechanical circulatory support. Autopsy revealed neutrophil infiltration, interstitial edema, and micro-abscesses containing masses of streptococci and neutrophilic phagocytosis within the myocardium. The patient did not meet the diagnostic criteria for acute rheumatic fever; thus, he was diagnosed with non-rheumatic streptococcal myocarditis. Non-rheumatic streptococcal myocarditis rarely recurs, but it can be fulminant upon recurrence. LEARNING OBJECTIVE: We report a rare case of recurrent fulminant non-rheumatic streptococcal myocarditis. Endomyocardial biopsy and autopsy revealed neutrophil infiltration and micro-abscesses containing bacterial masses of streptococci and neutrophilic phagocytosis in the myocardium. The patient did not meet the diagnostic criteria for acute rheumatic fever; thus, he was diagnosed with non-rheumatic streptococcal myocarditis. Non-rheumatic streptococcal myocarditis rarely recurs, but it can be fulminant upon recurrence.

The Impella 5.0 is an axial-flow percutaneous ventricular assist device used in patients with cardiogenic shock. Although the recommended period of use is 10 days or less, weaning can be delayed because of ongoing hemodynamic instability. In clinical practice, this device sometimes malfunctions during long-term management with heparin and must be replaced; however, the relationship between the duration of support with the initial and replacement Impella 5.0 and the changes in value of the purge system has not been fully elucidated. From July 2018 to May 2021, Impella 5.0 was implanted and used for more than 10 days in 11 patients at our institution. Four patients required Impella replacement because of device malfunction and the second Impella had purge system malfunction in all cases. The second Impella was used for a significantly shorter time than the first Impella (p = 0016). We calculated the ratio of purge pressure to purge flow rate and found that the ratio exceeded 50 mm Hg/mL/h in all cases with purge system malfunction. In conclusion, it is important to construct a treatment strategy considering the duration of use, because the risk of purge system malfunction is high after replaced Impella 5.0.

Cardiology and Cardiovascular Medicine - Abstract
Aims The 2021 Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation combining creatinine and cystatin C provides a better estimation of glomerular filtration rate (GFR) compared to the creatinine-only equation. Methods and results CKD-EPI creatinine-cystatin C equation (creatinine-cystatin) was compared to creatinine-only (creatinine) equation in a subpopulation of Prospective comparison of ARNI with ACEI to Determine Impact on Global Mortality and morbidity in Heart Failure (PARADIGM-HF). Patients were categorized according to difference in eGFR using the two equations: Group 1 (−10 and 10 mL/min/1.73 m2, i.e. creatinine-cystatin more than 10 mL/min higher than creatinine). Cystatin C and creatinine were available in 1966 patients at randomization. Median (interquartile range) eGFR difference was −0.7 (−6.4–4.8) mL/min/1.73 m2. Compared to creatinine, creatinine-cystatin led to a substantial reclassification of chronic kidney disease stages. Overall, 212 (11%) and 355 (18%) patients were reallocated to a better and worse eGFR category, respectively. Compared to patients in Group 2, those in Group 1 (lower eGFR with creatinine-cystatin) had higher mortality and those in Group 3 (higher eGFR with creatinine-cystatin) had lower mortality. Increasing difference in eGFR (due to lower eGFR with creatinine-cystatin compared to creatinine) was associated with increasing elevation of biomarkers (including N-terminal pro-B-type natriuretic peptide and troponin) and worsening Kansas City Cardiomyopathy Questionnaire clinical summary score. The reason why the equations diverged with increasing severity of heart failure was that creatinine did not rise as steeply as cystatin C. Conclusion The CKD-EPI creatinine-only equation may overestimate GFR in sicker patients. Clinical Trial Registration URL: https://www.clinicaltrials.gov; Unique Identifier: NCT01035255.

Case Report ,Cardiology and Cardiovascular Medicine - Abstract
Patients with dilated cardiomyopathy (DCM) sometimes show anti-mitochondrial M2 antibody (AMA-M2) positivity. We aimed to compare the characteristics of DCM cases with and without AMA-M2, and to describe cases of DCM with AMA-M2 positivity. A total of 84 patients with DCM were analyzed. Six patients (7.1 %) were positive for AMA-M2. Of these six patients, five (83.3 %) had primary biliary cirrhosis (PBC) and four (66.7 %) had myositis. Patients with AMA-M2 positivity had more atrial fibrillation and more premature ventricular contractions than those without. Left and right atrial longitudinal dimensions were larger in patients with AMA positivity (left atrium, 65.9 mm vs. 54.7 mm, p = 0.02; right atrium, 57.0 mm vs. 46.1 mm, p = 0.02). Of the six patients with AMA-M2 positivity, three underwent cardiac resynchronization therapy with defibrillator implantation and three required catheter ablation treatment. Steroids were used in three patients. One patient died of unresolved lethal arrhythmia and another required re-hospitalization for heart failure; the remaining four patients did not have adverse events. Patients with DCM with AMA-M2 positivity had a higher affinity for PBC and myositis than those without, and are characterized by atrial enlargement and arrhythmias. LEARNING OBJECTIVE: Patients with dilated cardiomyopathy sometimes exhibit anti-mitochondrial M2 antibody positivity. These patients are at higher risk for primary biliary cirrhosis and inflammatory myositis, and their cardiac disorders are characterized by atrial enlargement and various arrhythmias. The course of the disease up to the time of diagnosis and after steroid use varies, and the prognosis is poor in advanced cases.

The HATCH score is employed as a risk assessment tool for atrial fibrillation (AF) development. However, the impact of the HATCH score on the long-term adverse outcomes in patients with acute heart failure (AHF) remains unknown. We investigated the clinical value of the HATCH score in patients with AHF. From a multicenter AHF registry, we retrospectively evaluated 1543 consecutive patients who required hospitalization owing to AHF (median age, 78 [69-85] years; 42.3% women) from January 2012 to December 2019. These patients were divided into five risk groups based on their HATCH score at admission (scores 0, 1, 2, 3, and 4-7). The correlation between the HATCH score and the composite outcome, including all-cause mortality and re-hospitalization due to HF, was analyzed using Kaplan-Meier and Cox proportional-hazard analyses. The median HATCH score was 2 [1-3], and the median age was 78 years (69-85 years). During the follow-up period (median, 16.8 months), the composite endpoint occurred in 691 patients (44.8%), including 416 (27%) patients who died (with 65 [4.2%] in-hospitalization deaths) and 455 (29.5%) patients requiring re-hospitalizations due to HF. The Kaplan-Meier analysis showed a significant increase in the composite endpoint with an increasing HATCH score (log-rank, p 0.001). The multivariate Cox regression model revealed that the HATCH score was an independent predictor of the composite endpoint (hazard ratio [HR] 1.181; 95% confidence interval [CI]: 1.111-1.255; p 0.001) with all-cause mortality (HR 1.153, 95% CI 1.065-1.249; p 0.001) and re-hospitalizations due to HF (HR 1.21; 95% CI 1.124-1.303; p 0.001) in patients with AHF, regardless of the presence or absence of AF, ejection fraction, and etiology. The HATCH score is an independent predictor of adverse outcomes in patients with AHF.

Heart Failure ,Ventricular Dysfunction, Left ,Humans ,Stroke Volume ,Cardiology and Cardiovascular Medicine - Abstract
New guidelines have emphasized the primacy of starting the four key life-saving therapies for patients with heart failure and reduced ejection fraction as quickly as possible, with titration to 'target dose' of these, as secondary consideration. In this article, we examine the reasons for this change in emphasis and revisit the evidence regarding the dosing of pharmacological therapy in heart failure. We demonstrate the early benefits obtained with even low doses of most of the foundational therapies for heart failure and reduced ejection fraction. We also clarify that the 'target dose' of those therapies requiring titration was a goal based on tolerability and often not reached in trials, i.e. the proven benefits of our foundational therapies were demonstrated with an average dose that was less than target and many patients in these trials were treated with sub-target doses.

A left ventricular assist device (LVAD) is a treatment option for patients with end-stage heart failure; however, a certain number of patients on durable LVADs are diagnosed with malignancy. Radiation therapy (RT) for patients with durable LVADs has safety concerns, because RT may interfere with the device. Herein, we report a case of RT during durable LVAD management. A 48-year-old man with a durable LVAD was diagnosed with sinusitis. As his symptoms were resistant to drug therapy, endoscopic sinus surgery was performed, and extranodal NK/T-cell lymphoma, nasal type (ENKL) was pathologically detected. Since RT was the first-line treatment for ENKL, we conducted two types of irradiation experiments to determine whether RT can be safely performed in patients with durable LVADs as follows: (1) assessing the extent of the radiation levels at each site and evaluating device malfunction by irradiating the lesion sites in the patient model with the same protocol as planned, and (2) evaluating device malfunction by directly irradiating the durable LVAD equipment once at the scheduled total dose. The radiation doses at the pump, driveline, system controller, power cable, and power module of the durable LVAD reached 7.86 cGy, 6.34 cGy, 0.66 cGy, 0.38 cGy, and 0.14 cGy, respectively. In both experiments, durable LVAD malfunction or any type of alarm was not observed. We concluded that RT could be safely performed with chemotherapy in this patient and our irradiation experiments can be applied to RT for other malignancies.

AimsAortic valve calcification in aortic sclerosis, a precursor of aortic stenosis (AS), is not always present in all three leaflets; how calcification develops in each leaflet is unknown. We aimed to investigate the natural history of calcification development in each aortic valve leaflet and the prognostic value of the number of calcified leaflets.Methods and resultsIn a retrospective multicentre cohort study of patients undergoing haemodialysis without AS, we observed calcification development in each aortic valve leaflet using echocardiography. We investigated the association between the number of calcified leaflets and AS development and mortality using time-to-event analysis. Among the 1507 patients (mean age, 66 years; 66% male) included in the longitudinal echocardiography analysis, 709 (47%) had aortic sclerosis at baseline: one-leaflet calcified, 370 (52%); two-leaflet calcified, 215 (30%); and three-leaflet calcified, 124 (17%). The median time for one calcified leaflet increase was 3–4 years, and 251 (17%) patients developed AS during a median 3.2-year follow-up. The increased number of calcified aortic valve leaflets was associated with developing AS; compared with that of one-leaflet calcified, the adjusted hazard ratios (aHRs) [95% confidence intervals (CIs)] of two- and three-leaflet calcified were 2.12 (1.49–3.00) and 4.43 (3.01–6.52), respectively; the aHR (95% CI) per one calcified leaflet increase was 2.24 (1.96–2.55). It was also associated with all-cause mortality; the aHR (95% CI) per one calcified leaflet increase was 1.18 (1.08–1.27).ConclusionThe number of calcified aortic valve leaflets strongly predicted AS development and even mortality in patients undergoing haemodialysis, suggesting the usefulness of assessing calcification for each valve leaflet separately using echocardiography.

Cardiogenic shock with fulminant myocarditis is a life-threatening diagnosis. Extracorporeal membrane oxygenation (ECMO) with an Impella for left ventricle unloading is often required to maintain the haemodynamics. However, the small peripheral vascularity in small-bodied patients interrupts the upgrade from ECMO to Impella5.0, which usually requires grafting to a femoral artery or subclavian artery of at least 7 mm in size. This report outlines the external iliac artery approach, named the "ILIPELLA" technique, which uses a reconstructed external iliac artery to introduce Impella5.0 in patients with small peripheral vascularity.

Cardiology and Cardiovascular Medicine - Abstract
Aims: The effects of adding a sodium–glucose cotransporter 2 (SGLT2) inhibitor to a mineralocorticoid receptor antagonist (MRA) or an angiotensin receptor–neprilysin inhibitor (ARNI) in patients with heart failure (HF) and mildly reduced ejection fraction (HFmrEF) and preserved ejection fraction (HFpEF) are uncertain, even though the use of all three drugs is recommended in recent guidelines. Methods and results: The efficacy and safety of dapagliflozin added to background MRA or ARNI therapy was examined in patients with HFmrEF/HFpEF enrolled in the DELIVER trial. The primary outcome was the composite of worsening HF or cardiovascular death. Of 6263 patients, 2667 (42.6%) were treated with an MRA and 301 (4.8%) with an ARNI at baseline. Patients taking either were younger, more often men and had lower systolic blood pressure and ejection fraction; they were also more likely to have prior HF hospitalization. The benefit of dapagliflozin was similar whether patients were receiving these therapies. The hazard ratio for the effect of dapagliflozin compared to placebo on the primary outcome was 0.86 (95% confidence interval [CI] 0.74–1.01) for MRA non-users versus 0.76 (95% CI 0.64–0.91) for MRA users (pinteraction = 0.30). The corresponding values for ARNI non-users and users were 0.82 (95% CI 0.73–0.92) and 0.74 (95% CI 0.45–1.22), respectively (pinteraction = 0.75). None of the adverse events examined was more common with dapagliflozin compared to placebo overall or in the MRA and ARNI subgroups. Conclusions: The efficacy and safety of dapagliflozin were similar, regardless of background treatment with an MRA or ARNI. SGLT2 inhibitors may be added to other treatments recommended in recent guidelines for HFmrEF/HFpEF.

ImportanceIn 2 trials enrolling patients with heart failure (HF) across the spectrum of ejection fraction (EF), dapagliflozin has been shown to reduce the rate of the composite of worsening HF events or death from cardiovascular (CV) causes.ObjectiveTo examine the effects of dapagliflozin on cause-specific CV and non-CV mortality across the spectrum of EF.Design, Setting, and ParticipantsThis was a participant-level, pooled, prespecified secondary analysis of data from the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure, or DAPA-HF trial (participant left ventricular EF [LVEF] ≤40%), and Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure, or DELIVER trial (participant LVEF >40%), to assess the effects of randomized treatment on cause-specific mortality. The trials assigned adjacent populations of patients with chronic HF, New York Heart Association class II-IV symptoms, and elevated natriuretic peptides to treatment with dapagliflozin (10 mg, once daily) or placebo. The primary outcome for each study was a composite of worsening HF events (hospitalization or urgent heart failure visits) or CV death. Clinical outcomes, including all deaths, were adjudicated as to cause by clinical end points committees blinded to treatment assignment.InterventionDapagliflozin vs placebo.Main Outcomes and MeasuresThe mode of death in relation to baseline EF was examined, as well as the effect of randomized treatment on cause-specific death in Cox regression models. Relationships with continuous EF were modeled using Poisson regression.ResultsOf 11 007 patients in the pooled data set, there were 1628 deaths during follow-up (mean [SD] age, 71.7 [10.3] years; 1139 male [70.0%]). Of those who died, 872 (53.5%) were ascribed to CV deaths, 487 (29.9%) to non-CV deaths, and 269 (16.5%) to undetermined causes. Of CV deaths, 289 (33.1%; this represented 17.8% of total deaths) were due to HF, 441 (50.6%; 27.1% of total deaths) were sudden, 69 (7.9%; 4.2% of total deaths) were due to stroke, 47 (5.4%; 2.9% of total deaths) to myocardial infarction, and 26 (3.0%; 1.6% of total deaths) were due to other CV causes. The proportion of non-CV deaths was higher in those with higher EF. In the pooled population, across the spectrum of EF, treatment with dapagliflozin was associated with lower rates of CV death (hazard ratio [HR], 0.86; 95% CI, 0.75-0.98; P = .02), principally due to lower rates of sudden death (HR, 0.84; 95% CI, 0.70-1.01; P = .07) and HF death (HR, 0.88; 95% CI, 0.70-1.11; P = .30), with little difference in rates of death from stroke or MI.Conclusions and RelevanceIn a pooled analysis of patients with HF in the DAPA-HF and DELIVER randomized clinical trials, across the full spectrum of LVEF, dapagliflozin significantly reduced risks of CV death with contributions from lower rates of sudden death and death from progressive HF.Trial RegistrationClinicalTrials.gov Identifier: NCT03036124, NCT03619213

Case Report ,Cardiology and Cardiovascular Medicine - Abstract
Lipomatous hypertrophy of the interatrial septum is a rare benign condition characterized by adipocyte hyperplasia with fat infiltration between the myocardial fibers in the interatrial septum. Although lipomatous hypertrophy does not occur only in the interatrial septum, its location in the interventricular septum is extremely rare. A 45-year-old woman with no medical or family history of cardiac disease presented with an episode of syncope. Transthoracic echocardiography revealed an echogenic mass in the interventricular septum and no outflow obstruction. The mass-like area showed fat tissue-specific features on computed tomography and magnetic resonance imaging, and furthermore, it showed late gadolinium enhancement. We diagnosed it as lipomatous hypertrophy of the interventricular septum. An implantable loop recorder documented paroxysmal complete atrioventricular block with presyncope. A permanent dual-chamber pacemaker was implanted. This is the first reported case of lipomatous hypertrophy of the interventricular septum treated with a pacemaker for complete atrioventricular block with syncope. We have described the case and the treatment strategy in detail. LEARNING OBJECTIVE: To understand lipomatous hypertrophy, a rare disorder, and its characteristics and differences between lipomatous hypertrophy and cardiac adipose tumors on computed tomography and magnetic resonance imaging. To learn about the appropriate treatment and clinical management of this benign condition and treat symptomatic patients.

Aims Patients with acute heart failure (AHF) often present with an increased heart rate (HR), and the HR changes dramatically after initial treatment for AHF. However, the HR change after admission and the relationship between HR change in the early phase and prognosis have not been fully elucidated. Methods and results From a multicentre AHF registry, we retrospectively evaluated 1527 consecutive patients admitted with AHF. HR change (%) was calculated by [HR (at admission) − HR (24 h after admission)] × 100∕HR (at admission). The median HR change was 15.1% (range, 2.0–28.4%). The HR decreased most in the first 24 h and then gradually thereafter [admission: 98 (81–117) b.p.m., 24 h: 80 (70–92) b.p.m., 48 h: 78 (68–90) b.p.m., and 72 h: 77 (67–88) b.p.m.]. In Kaplan–Meier analysis, the cumulative event‐free rates in the composite endpoint of death and rehospitalization due to AHF showed better according to larger HR change (P = 0.012, log rank). Cox proportional hazards analysis showed that HR change was a prognostic factor for composite endpoint adjusted by age and sex [hazard ratio, 0.995; 95% confidence interval (CI), 0.991–0.998; P = 0.006]. HR change was associated with outcome adjusted by age and sex in patients with sinus rhythm (hazard ratio, 0.993; 95% CI, 0.988–0.999; P = 0.015), but not in patients with atrial fibrillation (hazard ratio, 0.996; 95% CI, 0.990–1.002; P = 0.15). Conclusions A decrease in HR in the first 24 h after admission indicates better prognosis in patients with AHF, although the prognostic influence may differ between patients with sinus rhythm and those with atrial fibrillation.

Aims In recent decades, haemodynamic parameters have been estimated for risk stratification and determining treatment strategies for patients with non‐ischaemic dilated cardiomyopathy (DCM). In various invasive procedures, the cardiac pumping capability is defined as cardiac power output (CPO), which is calculated by multiplying cardiac output by the mean arterial pressure. Lower CPO values in advanced heart failure predict adverse outcomes. However, few studies discuss the prognostic value of CPO in mild‐to‐moderate phase patients. This study aimed to determine the value of the cardiac power index (CPI) obtained from the resting CPO for predicting the prognosis of patients with New York Heart Association Functional Class II or III DCM. Methods and results From March 2000 to January 2020, a total of 623 cardiomyopathy patients were evaluated for haemodynamic parameters. Patients with secondary cardiomyopathy, ischaemic cardiomyopathy, valvular heart disease, and Class IV cardiomyopathy were excluded. A total of 176 DCM patients fulfilled the criteria for inclusion. Patients were 51.7 ± 12.5 years old (mean ± standard deviation) with a mean left ventricular ejection fraction of 32.1 ± 9.2%. The patients were divided into two groups by their median CPI (CPI

Aims Patients with heart failure with reduced ejection fraction (HFrEF) are at significant risk of stroke. Anticoagulation reduces this risk in patients with and without atrial fibrillation (AF), but the risk-to-benefit balance in the latter group, overall, is not favourable. Identification of patients with HFrEF, without AF, at the highest risk of stroke may allow targeted and safer use of prophylactic anticoagulant therapy. Methods and results In a pooled patient-level cohort of the PARADIGM-HF, ATMOSPHERE, and DAPA-HF trials, a previously derived simple risk model for stroke, consisting of three variables (history of prior stroke, insulin-treated diabetes, and plasma N-terminal pro-B-type natriuretic peptide level), was validated. Of the 20 159 patients included, 12 751 patients did not have AF at baseline. Among patients without AF, 346 (2.7%) experienced a stroke over a median follow up of 2.0 years (rate 11.7 per 1000 patient-years). The risk for stroke increased with increasing risk score: fourth quintile hazard ratio (HR) 2.35 [95% confidence interval (CI) 1.60–3.45]; fifth quintile HR 3.73 (95% CI 2.58–5.38), with the first quintile as reference. For patients in the top quintile, the rate of stroke was 21.2 per 1000 patient-years, similar to participants with AF not receiving anticoagulation (20.1 per 1000 patient-years). Model discrimination was good with a C-index of 0.84 (0.75–0.91). Conclusion It is possible to identify a subset of HFrEF patients without AF with a stroke-risk equivalent to that of patients with AF who are not anticoagulated. In these patients, the risk-to-benefit balance might justify the use of prophylactic anticoagulation, but this hypothesis needs to be tested prospectively.

Aims Obesity is common and associated with unique phenotypic features in heart failure with preserved ejection fraction (HFpEF). Therefore, understanding the efficacy and safety of new therapies in HFpEF patients with obesity is important. The effects of dapagliflozin were examined according to body mass index (BMI) among patients in the Dapagliflozin Evaluation to Improve the LIVEs of Patients With PReserved Ejection Fraction Heart Failure trial. Methods and results Body mass index was analysed by World Health Organization (WHO) categories and as a continuous variable using restricted cubic splines. Body mass index ranged from 15.2 to 50 kg/m2 with a mean value of 29.8 (standard deviation ± 6.1) kg/m2. The proportions, by WHO category, were: normal weight 1343 (21.5%); overweight 2073 (33.1%); Class I obesity 1574 (25.2%); Class II obesity 798 (12.8%); and Class III obesity 415 (6.6%). Compared with placebo, dapagliflozin reduced the risk of the primary outcome to a similar extent across these categories: hazard ratio (95% confidence interval): 0.89 (0.69–1.15), 0.87 (0.70–1.08), 0.74 (0.58–0.93), 0.78 (0.57–1.08), and 0.72 (0.47–1.08), respectively (P-interaction = 0.82). The placebo-corrected change in Kansas City Cardiomyopathy Questionnaire total symptom score with dapagliflozin at 8 months was: 0.9 (−1.1, 2.8), 2.5 (0.8, 4.1), 1.9 (−0.1, 3.8), 2.7 (−0.5, 5.8), and 8.6 (4.0, 13.2) points, respectively (P-interaction = 0.03). The placebo-corrected change in weight at 12 months was: –0.88 (−1.28, –0.47), –0.65 (−1.04, –0.26), –1.42 (−1.89, –0.94), –1.17 (−1.94, –0.40), and –2.50 (−4.4, –0.64) kg (P-interaction = 0.002). Conclusions Obesity is common in patients with HFpEF and is associated with higher rates of heart failure hospitalization and worse health status. Treatment with dapagliflozin improves cardiovascular outcomes across the spectrum of BMI, leads to greater symptom improvement in patients with obesity, compared with those without, and has the additional benefit of causing modest weight loss.

International audience; Aims: Biomarker-driven prognostic models incorporating N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) in heart failure (HF) with preserved ejection fraction (HFpEF) are lacking. We aimed to generate a biomarker-driven prognostic tool for patients with chronic HFpEF enrolled in EMPEROR-Preserved.Methods and results: Multivariable Cox regression models were created for (i) the primary composite outcome of HF hospitalization or cardiovascular death, (ii) all-cause death, (iii) cardiovascular death, and (iv) HF hospitalization. PARAGON-HF was used as a validation cohort. NT-proBNP and hs-cTnT were the dominant predictors of the primary outcome, and in addition, a shorter time since last hospitalization, New York Heart Association (NYHA) class III or IV, history of chronic obstructive pulmonary disease (COPD), insulin-treated diabetes, low haemoglobin, and a longer time since HF diagnosis were key predictors (eight variables, all p < 0.001). The consequent primary outcome risk score discriminated well (c-statistic = 0.75) with patients in the top 10th of risk having an event rate >22× higher than those in the bottom 10th. A model for HF hospitalization alone had even better discrimination (c = 0.79). Empagliflozin reduced the risk of cardiovascular death or hospitalization for HF in patients across all risk levels. NT-proBNP and hs-cTnT were also the dominant predictors of all-cause and cardiovascular mortality followed by history of COPD, low albumin, older age, left ventricular ejection fraction ≥50%, NYHA class III or IV and insulin-treated diabetes (eight variables, all p < 0.001). The mortality risk model had similar discrimination for all-cause and cardiovascular mortality (c-statistic = 0.72 for both). External validation provided c-statistics of 0.71, 0.71, 0.72, and 0.72 for the primary outcome, HF hospitalization alone, all-cause death, and cardiovascular death, respectively.Conclusions: The combination of NT-proBNP and hs-cTnT along with a few readily available clinical variables provides effective risk discrimination both for morbidity and mortality in patients with HFpEF. A predictive tool-kit facilitates the ready implementation of these risk models in routine clinical practice.

Heart failure (HF) causes a hypercatabolic state that enhances the catabolic activity of branched-chain amino acids (BCAA; leucine, isoleucine, and valine) in the heart and skeletal muscles and reduces protein synthesis in the liver. Consequently, free plasma aromatic amino acids (AAA, tyrosine and phenylalanine) are increased. To date, we have reported the prognostic value of the BCAA/AAA ratio (Fischer’s ratio) in patients with HF. However, the leucine/phenylalanine ratio, which is a simpler index than the Fischer’s ratio, has not been examined. Therefore, the prognostic value of the leucine/phenylalanine ratio in patients with HF was investigated. Overall 157 consecutive patients hospitalized for worsening HF (81 men, median age 78 years) were enrolled in the study. Plasma amino acid levels were measured when the patients were stabilized at discharge. Cardiac events were defined as a composite of cardiac death and hospitalization for worsening HF. A total of 46 cardiac events occurred during the median follow-up period of 238 (interquartile range 93–365) days. The median leucine/phenylalanine ratio was significantly lower in patients with cardiac events than in those without cardiac events (1.4 vs. 1.8, P

Aims Left ventricular reverse remodelling (LVRR) is a well‐established predictor of a good prognosis in patients with dilated cardiomyopathy (DCM). The prediction of LVRR is important when developing a long‐term treatment strategy. This study aimed to assess the clinical predictors of LVRR and establish a scoring system for predicting LVRR in patients with DCM that can be used at any institution. Methods and results We consecutively enrolled 131 patients with DCM and assessed the clinical predictors of LVRR. LVRR was defined as an absolute increase in left ventricular ejection fraction (LVEF) from ≥10% to a final value of >35%, accompanied by a decrease in left ventricular end‐diastolic dimension (LVEDD) ≥ 10% on echocardiography at 1 ± 0.5 years after a diagnosis of DCM. The mean patient age was 50.1 ± 11.9 years. The mean LVEF was 32.2 ± 9.5%, and the mean LVEDD was 64.1 ± 12.5 mm at diagnosis. LVRR was observed in 45 patients (34%) at 1 ± 0.5 years.

A 37-year-old man diagnosed with diffuse large B-cell lymphoma two weeks previously, visited our emergency department with sudden dyspnea. He had a severe respiratory failure with saturated percutaneous oxygen at 80% (room air). Chest radiography showed a large amount of left pleural effusion. After 1000 mL of the effusion was urgently drained, reexpansion pulmonary edema (RPE) occurred. Despite ventilator management, oxygenation did not improve and venovenous extracorporeal membrane oxygenation (VV-ECMO) was initiated in the intensive care unit. The next day, contrast-enhanced computed tomography showed a massive thrombus in the right pulmonary artery, at this point the presence of pulmonary thromboembolism (PTE) was revealed. Fortunately, the patient’s condition gradually improved with anticoagulant therapy and VV-ECMO support. VV-ECMO was successfully discontinued on day 4, and chemotherapy was initiated on day 8. We speculated the following mechanism in this case: blood flow to the right lung significantly reduced due to acute massive PTE, and blood flow to the left lung correspondingly increased, which could have caused RPE in the left lung. Therefore, our observations suggest that drainage of pleural effusion when contralateral blood flow is impaired due to acute PTE may increase the risk of RPE.

We treated two patients with COVID-19 pneumonia requiring mechanical ventilation. Case 1 was a 73-year-old Japanese man. Computed tomography (CT) revealed ground-glass opacities in both lungs. He had severe respiratory failure with a partial pressure of oxygen in arterial blood/fraction of inspiratory oxygen ratio (P/F ratio) of 203. Electrocardiogram showed a heart rate (HR) of 56 beats/min, slight ST depression in leads II, III, and aVF, and mild saddle-back type ST elevation in leads V1 and V2. High-sensitivity cardiac troponin T (cTnT) level was slightly elevated. Despite a high fever and hypoxemia, his HR remained within 50-70 beats/min. Case 2 was a 52-year-old Japanese woman. CT revealed ground-glass opacities in the lower left lung. Electrocardiogram showed a HR of only 81 beats/min, despite a body temperature of 39.2 °C, slight ST depression in leads V4, V5, V6, and a prominent U wave in multiple leads. She had an elevated cTnT and a P/F ratio of 165. Despite a high fever and hypoxemia, her HR remained within 50-70 beats/min. Both patients had a poor compensatory increase in their HR, despite their critical status. Relative bradycardia could be a cardiovascular complication and is an important clinical finding in patients with COVID-19. .

Delirium is a common adverse event observed in patients admitted to the intensive care unit (ICU). However, the prognostic value of delirium and its determinants have not been thoroughly investigated in patients with acute heart failure (AHF).We investigated 408 consecutive patients with AHF admitted to the ICU. Delirium was diagnosed by means of the Confusion Assessment Method for ICU tool and evaluated every 8 hours during the patients' ICU stays.Delirium occurred in 109 patients (26.7%), and the in-hospital mortality rate was significantly higher in patients with delirium (13.8% vs 2.3%; P0.001). Multivariate logistic regression analysis showed that delirium independently predicted in-hospital mortality (odds ratio [OR] 4.33, confidence interval [CI] 1.62-11.52; P = 0.003). Kaplan-Meier analysis showed that the 12-month mortality rate was significantly higher in patients with delirium compared with those without (log-rank test: P0.001), and Cox proportional hazards analysis showed that delirium remained an independent predictor of 12-month mortality (hazard ratio 2.19, 95% CI 1.49-3.25; P0.001). The incidence of delirium correlated with severity of heart failure as assessed by means of the Get With The Guidelines-Heart Failure risk score (chi-square test: P = 0.003). Age (OR 1.05, 95% CI 1.02-1.09; P = 0.003), nursing home residential status (OR 3.32, 95% CI 1.59-6.94; P = 0.001), and dementia (OR 5.32, 95% CI 2.83-10.00; P0.001) were independently associated with the development of delirium.Development of delirium during ICU stay is associated with short- and long-term mortality and is predicted by the severity of heart failure, nursing home residential, and dementia status.

Background Kawasaki disease (KD) is a self-limiting form of systemic vasculitis. KD usually occurs in infants and young children and is rarely seen in adolescents. On rare occasions, KD is accompanied with reduced organ perfusion due to systolic hypotension, a condition known as Kawasaki disease shock syndrome (KDSS). The multifactorial causes of KDSS may include intensive vasculitis with capillary leak, myocardial dysfunction, and release of proinflammatory cytokines. However, the mechanisms underlying the pathophysiology of KDSS have not been fully elucidated. Case summary A febrile 17-year-old male with cervical lymphadenopathy developed extreme shock with rapid cardiac dysfunction and reduced organ perfusion. Electrocardiogram revealed ST elevation in the precordial leads and increased serum levels of cardiac enzyme levels. Endomyocardial biopsy at the acute phase revealed CD3+, CD4+ or CD8+, and CD20− lymphocytes and CD68+ macrophages within infiltrates in the myocardium with mild interstitial fibrosis. He was treated with intravenous immunoglobulin (IVIG) and followed by glucocorticoids with mechanical circulatory support. His cardiac function recovered rapidly with no apparent adverse effects. Discussion Our results suggest that KDSS may be a form of myocarditis, a condition in which inflammatory cells infiltrate the myocardium. Early immunosuppressive therapy, including IVIG and glucocorticoid therapy, may limit the severity of disease and improve the prognosis. As shown by this case, an accurate diagnosis of KD and KDSS will lead to early intervention and improved prognosis even among those in an older cohort.

BACKGROUND Right ventricular dysfunction (RVD) in the setting of left ventricular (LV) myocardial damage is a major cause of morbidity and mortality, and the pulmonary artery pulsatility index (PAPi) is a novel hemodynamic index shown to predict RVD in advanced heart failure. However, it is unknown whether PAPi can predict the long-term prognosis of dilated cardiomyopathy (DCM) even in the mild to moderate phase. This study aimed to assess the ability of PAPi to stratify DCM patients without severe symptoms.Methods and Results:Between April 2000 and March 2018, a total of 162 DCM patients with stable symptoms were evaluated, including PAPi, and followed up for a median of 4.91 years. The mean age was 50.9±12.6 years and the mean LV ejection fraction (EF) was 30.5±8.3%. When divided into 2 groups based on median value of PAPi (low, L-PAPi [

The Impella is an axial-flow percutaneous ventricular assist device for cardiogenic shock. In this report, we describe two patients who developed aortic insufficiency (AI) associated with Impella and required surgical intervention upon implantation of the durable left ventricular assist device (LVAD). Both patients presented with cardiogenic shock and underwent insertion of Impella 5.0 as a bridge to decision. The cardiac function in these patients did not improve and obtaining approval for heart transplantation required time. They were managed with Impella for 91 and 98 days, respectively. In both cases, moderate AI that was not present before Impella insertion was observed when the Impella was removed. Therefore, we performed aortic valve closure to control the AI during durable LVAD implantation. In patients with durable LVAD implantation, AI may occur and progress after the operation in several cases. Aortic valve surgery is often performed to prevent deterioration of AI, especially in patients with AI before the surgery. Hence, AI is an important complication following Impella device implantation as a bridge to decision. Careful observation of AI is essential when the Impella is removed as the evaluation of AI by echocardiogram during Impella management is cumbersome because of device-generated artifacts.

Background Prognoses and long‐term cardiac function of patients with fulminant myocarditis have not been fully elucidated. Therefore, we clarified the prognoses and long‐term cardiac function according to required percutaneous mechanical circulatory support and histological findings among patients with fulminant myocarditis. Methods and Results We conducted a multicenter retrospective medical record review of 216 patients with fulminant myocarditis requiring percutaneous mechanical circulatory support. Sixty‐one patients were treated with intra‐aortic balloon pump or Impella alone, and 155 patients received veno‐arterial extracorporeal membrane oxygenation and were treated with or without intra‐aortic balloon pump or Impella. Histologically, 107 patients had lymphocytic myocarditis; 34, eosinophilic myocarditis; and 4, giant cell myocarditis. Freedom from composite end point (death, durable left ventricular assist device implantation, and heart transplantation) was 66% at 90 days, 62% at 1 year, and 57% at 6 years. Veno‐arterial extracorporeal membrane oxygenation use was associated with poor prognosis in the multivariable analysis (hazard ratio [HR], 5.27; 95% CI, 1.60–17.36). The eosinophilic myocarditis subgroup showed better prognosis (HR, 0.28; 95% CI, 0.10–0.80) compared with the lymphocytic myocarditis subgroup but not in the multivariable analysis. Ventricular tachycardia/ventricular fibrillation rhythm at admission, high C‐reactive protein level, and no endomyocardial biopsy were also associated with poor prognosis. The left ventricular ejection fraction at 1 year was ≤50% in 16% of patients and was lower in patients with eosinophilic myocarditis (median: 57.9% [48.8–65.0%]) than in those with lymphocytic myocarditis (65.0% [58.6–68.7%]) ( P =0.036). Conclusions Patients with fulminant myocarditis who received veno‐arterial extracorporeal membrane oxygenation had a poor prognosis. Long‐term cardiac function was impaired in some patients, especially those with eosinophilic myocarditis.

Many patients with dilated cardiomyopathy (DCM) progress to heart failure (HF), although some demonstrate left ventricular (LV) reverse remodeling (LVRR), which is associated with better outcomes. The pulmonary artery diameter (PAD) to ascending aortic diameter (AoD) ratio has been used as a prognostic predictor in patients with HF, although this tool's usefulness in predicting LVRR remains unknown.Methods and Results: Data from a prospective observational study of 211 patients diagnosed in 2000-2020 with DCM were retrospectively analyzed. Sixty-nine patients with New York Heart Association class I or II HF were included. LVRR was observed in 23 patients (33.3%). The mean LV ejection fraction (29%) and LV end-diastolic dimension (64.5 mm) were similar in patients with and without LVRR. The PAD/AoD ratio was significantly lower in patients with LVRR than those without (81.4% vs. 92.4%, respectively; P=0.003). The optimal PAD/AoD cut-off value for detecting LVRR was 0.9 according to the receiver operating characteristic curve analysis. Multivariate analysis identified a PAD/AoD ratio ≥0.9 as an independent predictor of presence/absence of LVRR. Cardiac events were significantly more common in patients with a PAD/AoD ratio ≥0.9 than those with a ratio0.9, after a median follow up of 2.5 years (log-rank, P=0.007).The PAD/AoD ratio can predict LVRR in patients with DCM.

Autotaxin (ATX) promotes myocardial inflammation, fibrosis, and the subsequent cardiac remodelling through lysophosphatidic acid production. However, the prognostic impact of serum ATX in non-ischaemic dilated cardiomyopathy (NIDCM) has not been clarified. We investigated the prognostic impact of serum ATX in patients with NIDCM.We enrolled 104 patients with NIDCM (49.8 ± 13.4 years, 76 men). We divided the patients into two groups using different cutoffs of median serum ATX levels for men and women: high-ATX group and low-ATX group. Cardiac events were defined as a composite of cardiac death and heart failure resulting in hospitalization. Median ATX level was 203.5 ng/mL for men and 257.0 ng/mL for women. Brain natriuretic peptide levels [224.0 (59.6-689.5) pg/mL vs. 96.5 (40.8-191.5) pg/mL, P = 0.010] were higher in the high-ATX group than low-ATX group, whereas high-sensitivity C-reactive protein and collagen volume fraction levels in endomyocardial biopsy samples were not significantly different between the two groups. Kaplan-Meier survival analysis revealed that the event-free survival rate was significantly lower in the high-ATX group than low-ATX group (log-rank; P = 0.007). Cox proportional hazard analysis revealed that high-ATX was an independent determinant of composite cardiac events. In both sexes, serum ATX levels did not correlate with high-sensitivity C-reactive protein levels and collagen volume fraction but had a weak correlation with brain natriuretic peptide levels (men; spearman's rank: 0.274, P = 0.017, women; spearman's rank: 0.378, P = 0.048).High serum ATX levels can be associated with increasing adverse clinical outcomes in patients with NIDCM. These results indicate serum ATX may be a novel biomarker or therapeutic target in NIDCM.

Heart failure (HF) is a systemic inflammatory disease that causes hypotrophy and skeletal muscle loss. The Global Leadership Initiative on Malnutrition (GLIM) criteria have been developed as a novel evaluation index for malnutrition, with reported usefulness in HF caused by ischemic heart disease. However, reports on the usefulness of malnutrition evaluated by the GLIM criteria in non-ischemic dilated cardiomyopathy (NIDCM) and its relationship with psoas muscle volume are lacking. We investigated the prognostic value of malnutrition evaluated using the GLIM criteria and its association with psoas muscle volume in patients with NIDCM. We enrolled 139 consecutive patients with NIDCM between December 2000 and June 2020. Malnutrition was evaluated using the GLIM criteria on admission. The median follow-up period was 4.7 years. Cardiac events were defined as a composite of cardiac death, hospitalization for worsening HF, and lethal arrhythmia. Furthermore, we measured the psoas muscle volume using computed tomography volumetry in 48 patients. At baseline, the median age was 50 years, and 132 patients (95.0%) had New York Heart Association functional class I or II HF. The median psoas muscle volume was 460.8 cm

The spleen is an important immune organ that releases erythrocytes and monocytes and destroys aged platelets. It also reserves 20-30% of the total blood volume, and its size decreases in hypovolemic shock. However, the clinical significance of splenic size in patients with heart failure (HF) remains unclear. We retrospectively analyzed the data of 206 patients with clinically stable HF gathered between January 2001 and August 2020 and recorded in a single-center registry. All patients underwent right heart catheterization and computed tomography (CT). Splenic size was measured using CT volumetry. The primary outcomes were composite cardiac events occurring for the first time during follow-up, namely, cardiac death and hospitalization for worsening HF. The median splenic volume and splenic volume index (SVI) were 118.0 mL and 68.9 mL/m

Transportation of patients with coronavirus disease (COVID)-19 outside isolation rooms should be avoided to prevent further spread of the disease. Here, we report a safe and accurate bedside cannulation method for veno-venous extracorporeal membrane oxygenation (VV-ECMO) in a COVID-19 patient in the intensive care unit. A 71-year-old man was admitted to our hospital and diagnosed as having COVID-19 pneumonia. We decided to initiate VV-ECMO therapy because maintaining blood oxygen saturation was difficult despite the mechanical ventilation. We placed two flat-panel detectors behind the patient's chest and the right inguinal area. We repeatedly imaged and monitored insertion of wires and cannulas using a portable X-ray system. Cannulas were successfully inserted in the appropriate position, and VV-ECMO was initiated without any complications.

A 51-year-old male, previously diagnosed with central diabetes insipidus due to lymphocytic hypophysitis, presented with fever and dyspnea for 1 week. On arrival, he exhibited hypotension (85/60 mmHg) and sinus tachycardia (110 bpm). His electrocardiogram revealed mild ST elevation on V2–V4. Echocardiography indicated a near-normal (50%) left ventricular ejection fraction (LVEF), although the inferior wall of the left ventricle exhibited severe hypokinesis. Fulminant myocarditis and circulatory insufficiency were suspected, and treatment with dobutamine, 3 μg/kg/min, was started. His LVEF gradually decreased to 20%. On day 17, he developed cardiogenic shock due to ventricular tachycardia and underwent peripheral venous–arterial extracorporeal membrane oxygenation and intra-aortic balloon pumping. Although he did not exhibit polyuria, intravenous vasopressin infusion (0.5 U/h) was performed to maintain normonatremia. Endomyocardial biopsy results revealed the infiltration of scattered giant cells (GCs) and extensive lymphocytes. Despite immunosuppressive therapy (methylprednisolone and cyclosporine), his cardiac function did not recover. On day 36, he received a biventricular assist device; however, he died on day 47 due to the progression of sepsis and multiple organ failure. We speculate that a deficient expression of programmed cell death protein-1 was the cause of both GC myocarditis and lymphocytic hypophysitis.

BACKGROUND Intravenous vasodilators are commonly used in patients with hypertensive acute decompensated heart failure (ADHF), but little is known about their optimal use in blood pressure (BP) management to avoid acute kidney injury (AKI). The purpose of this study was to investigate the association between systolic BP (SBP) changes and the incidence of AKI in patients with hypertensive ADHF.Methods and Results:Post-hoc analysis was performed on a prospectively enrolled cohort. We investigated 245 patients with ADHF and SBP >140 mmHg on arrival (mean age, 76 years; 40% female). We defined "SBP-fall" as the maximum percent reduction in SBP 6 h after intravenous treatment. AKI was defined as serum creatinine (SCr) ≥0.3 mg/dL, or urine output

Purpose: Diastolic dysfunction preceding systolic dysfunction is considered an important interaction in cardiomyopathy with poor prognosis. The aim of this study was to compare left ventricular (LV) isovolumic relaxation with the other parameters as a potential prognostic marker for patients with idiopathic dilated cardiomyopathy (IDC) and hypertrophic cardiomyopathy (HC). Methods: A total of 145 patients with IDC and 116 with HC were evaluated for hemodynamic parameters; LV pressure was directly measured by a micromanometer catheter, and relaxation half-time (T1/2) was used to determine LV isovolumic relaxation. The median follow-up period was 4.7 years. Results: The mean ages of the patients with IDC and HC were 52.0 ± 12.0 and 57.1 ± 12.4 years, respectively. Each patient group was further divided into 2 groups based on the median value of T1/2: (1), ファイル公開:2020-08-01

Background Follistatin-like 1 (FSTL1) is a myocyte-secreted glycoprotein that could play a role in myocardial maintenance in response to harmful stimuli. We investigated the association between serum FSTL1 levels, especially focused on transcardiac gradient and the hemodynamics, to explore the prognostic impact of FSTL1 levels in patients with dilated cardiomyopathy (DCM). Methods Thirty-two ambulatory patients with DCM (23 men; mean age 59 years) were prospectively enrolled. Blood samples were simultaneously collected from the aortic root (Ao), coronary sinus (CS), as well as from the peripheral vein during cardiac catheterization in stable conditions. The transcardiac gradient of FSTL1 was calculated by the difference between serum FSTL1 levels of CS and Ao (FSTL1CS-Ao). Patients were divided into two groups based on the median of FSTL1CS-Ao: Low FSTL1CS-Ao group, Results Mean left ventricular ejection fraction and median plasma B-type natriuretic peptide levels were 30.9% and 92.3 pg/mL, respectively. FSTL1CS-Ao was negatively correlated with pulmonary capillary wedge pressure (r = -0.400, p = 0.023). Kaplan-Meier survival analysis showed that event-free survival rate was significantly lower in the Low FSTL1CS-Ao group than in the High FSTL1CS-Ao group (p = 0.013). Cox regression analyses revealed that the transcardiac gradient of FSTL1 was an independent predictor for cardiac events. Receiver operating characteristic curve analysis showed that the cut-off value of FSTL1CS-Ao for the prediction of cardiac events was -4.09 ng/mL with sensitivity of 82% and specificity of 86% (area under the curve, 0.87). Conclusions Fifty percent of patients had negative transcardiac gradient of FSTL1. Reduced transcardiac gradient of FSTL1 might be a novel prognostic predictor in DCM patients with impaired hemodynamics.

Background and aims Mild-to-moderate aortic stenosis (AS) and aortic sclerosis, a precursor of AS, are associated with mortality in the general population; however, their association in patients undergoing hemodialysis with higher morbidity of AS is unknown. Thus, we investigated the mortality of aortic sclerosis and mild-to-moderate AS in patients undergoing hemodialysis. Methods This was a retrospective multicenter cohort study of consecutive patients undergoing hemodialysis at nine dialysis facilities who underwent screening echocardiography between January 2008 and December 2019. We investigated the mortality of patients with aortic sclerosis or mild-to-moderate AS using multivariable Cox proportional hazards regression. Results Among 1,878 patients undergoing hemodialysis, those with normal aortic valves, aortic sclerosis, mild AS, moderate AS, severe AS, and prosthetic aortic valves were 844 (45%), 793 (42%), 161 (8.6%), 38 (2.0%), 11 (0.6%), and 31 (1.7%), respectively. After excluding patients with severe AS and prosthetic aortic valves, we performed comparative analysis on 1,836 patients (mean age, 67 years; 66% male). In a median follow-up of 3.6 years, crude death rates (per 100 person-years) were 5.2, 10.6, and 13.0 in patients with normal aortic valves, aortic sclerosis, and mild-to-moderate AS, respectively. Compared with normal aortic valves, both aortic sclerosis and mild-to-moderate AS were associated with all-cause and cardiovascular death: adjusted hazard ratios (95% confidence intervals) were 1.36 (1.13–1.65) and 1.36 (1.02–1.80) for all-cause death; and 1.52 (1.06–2.17) and 1.74 (1.04–2.92) for cardiovascular death, respectively. Conclusions Aortic sclerosis and mild-to-moderate AS were independent risk factors for all-cause and cardiovascular death in patients undergoing hemodialysis.
