Association of Multiple Nonhypertrophic Cardiomyopathy-Related Genetic Variants and Outcomes in Patients With Hypertrophic Cardiomyopathy.

Background: Approximately 10% of hypertrophic cardiomyopathy (HCM) patients have left ventricular systolic dysfunction (end-stage HCM) leading to severe heart-failure; however, risk stratification to identify patients at risk of progressing to end-stage HCM remains insufficient.

Objectives: In this study, the authors sought to elucidate whether the coexistence of other cardiovascular disease (CVD)-related variants is associated with progression to end-stage HCM in patients with HCM harboring pathogenic or likely pathogenic (P/LP) sarcomeric variants.

Methods: The authors performed genetic analysis of 83 CVD-related genes in HCM patients from a Japanese multicenter cohort.

The effects of bolus isosorbide dinitrate on pulmonary hypertension with cardiopulmonary comorbidities.

Lowering mean pulmonary arterial pressure (mPAP) without reducing cardiac output is essential in treating pulmonary hypertension (PH). Isosorbide dinitrate (ISDN) potentially achieves this in post-capillary PH but can decrease cardiac output and blood pressure (BP), especially in pre-capillary PH. However, post-capillary PH and pre-capillary PH can overlap, and their clear discrimination is difficult.

Increasing survivors of anthracycline-related cardiomyopathy with breast cancer in trastuzumab era: thirty-one-year trends in a Japanese Community.

Background: Trastuzumab has improved breast cancer (BC) prognosis and reduced anthracycline use. However, the characteristic changes of anthracycline-related cardiomyopathy (ARCM) in patients with BC remain unclear. We aimed to update our understanding of ARCM in the trastuzumab era.

Pd/Pa fluctuation with continuous ATP administration indicates inaccurate FFR measurement caused by insufficient hyperemia.

Continuous intravenous adenosine triphosphate (ATP) administration is the standard method for inducing maximal hyperemia in fractional flow reserve (FFR) measurements. Several cases have demonstrated fluctuations in the ratio of mean distal coronary pressure to mean arterial pressure (Pd/Pa) value during ATP infusion, which raised our suspicions of FFR value inaccuracy. This study aimed to investigate our hypothesis that Pd/Pa fluctuations may indicate inaccurate FFR measurements caused by insufficient hyperemia.

Usefulness of the Glove Finger Pad for Ultrasonography in Nasal Fracture Reduction.

The treatment of nasal bone fractures involves closed reduction, in which the reduction position is generally evaluated indirectly by visual examination and palpation. While more direct evaluation methods using ultrasonography can improve treatment outcomes, ultrasonography of the nasal bones requires acoustic coupling materials to hold the entire ultrasonography probe in close contact with the nose. We report the use of the Glove Finger Pad, a homemade acoustic coupling material made from a medical glove.

Reconstruction of Skin Defects in the Medial Canthal Region Using the Novel Hug Flap.

Various methods of reconstructing skin defects in the medial canthal region have been reported. We report 2 skin flaps for the upper and lower eyelids designed to reconstruct soft tissue defects in the medial canthal region based on the approach used for the orbit during surgeries for facial bone fractures. The skin flap was elevated without tension until it reached the defect.

Successful β-blocker introduction under intra-aortic balloon pumping and ivabradine in a patient with new-onset dilated cardiomyopathy and pulsus alternans: a case report.

Background: Pulsus alternans has been considered a sign of poor prognosis in patients undergoing treatments for heart failure. However, it may be overlooked in patients with intra-aortic balloon pumps (IABPs). The use of IABP and ivabradine for a β-blocker introduction in a patient with dilated cardiomyopathy (DCM) and pulsus alternans and its consequence have never been reported.

Sunflower cake versus soybean meal and alfalfa for nitrogen utilization when crude protein and non-fiber carbohydrate levels are equivalent.

The reported efficiency of N usage by sunflower cake (SFC) was inferior to that of soybean meal (SBM) in a study in which the non-fiber carbohydrate (NFC) content was lower in the SFC diet. Here, we adjusted crude protein (CP) and NFC levels to near-equivalence among three diets containing SFC or SBM for four non-lactating Holstein cows. Alfalfa hay was also added to the comparison.

A case of giant cell myocarditis mimicking cardiac sarcoidosis successfully maintained by prednisolone and tacrolimus.

Unlabelled: A 45-year-old woman with no medical history underwent pacemaker implantation for a symptomatic complete atrioventricular block. On day 6, she noticed diplopia and then fever, general malaise, and elevation of serum creatinine kinase (CK). She was transferred to our hospital on day 21.

Relationship Between Medical Therapy, Long-Term Care Insurance, and Comorbidity in Elderly Patients With Heart Failure With Systolic Dysfunction.

Background: Although guideline-directed medical therapy (GDMT), including β-blockers, angiotensin-converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARBs), and mineralocorticoid receptor antagonists (MRAs), improves survival and quality of life, most patients with heart failure with reduced (HFrEF) and mildly reduced (HFmrEF) ejection fraction are treated with inadequate medications. We investigated the prescription patterns of GDMT in elderly patients with HFrEF and HFmrEF and their characteristics, including the certification of long-term care insurance (LTCI), which represents frailty and disability.

Methods and results: This retrospective cross-sectional study analyzed 1,296 elderly patients with symptomatic HFrEF and HFmrEF with diuretic use (median age 78 years; 63.

Optimal Timing of Serial F-Fluoro-2-Deoxyglucose Positron Emission Tomography after Prednisolone Treatment Introduction for Cardiac Sarcoidosis.

Immunosuppressive therapy with prednisolone (PSL) is the first-line treatment for cardiac sarcoidosis (CS), and F-fluoro-2-deoxyglucose positron emission tomography (FDG-PET) is used to evaluate its efficacy to guide treatment. However, the appropriate timing of FDG-PET in CS remains unknown. This single-center, retrospective, observational study included 15 consecutive CS patients who underwent 3 serial FDG-PET scans (at baseline, in the early phase [1-2 months after PSL introduction], and in the late phase [≥ 5 months after PSL introduction with a maintenance dose of PSL]).

Precision dual-comb spectroscopy using wavelength-converted frequency combs with low repetition rates.

Precision spectroscopy contributed significantly to the development of quantum mechanics in its early stages. In the twenty-first century, precision spectroscopy has played an important role in several fields, including fundamental physics, precision measurement, environmental monitoring, and medical diagnostics. An optical frequency comb is indispensable in determining the frequency axis in precision spectroscopy and it is useful as a light source for spectroscopy.

Baseline Blood Pressure and Left Ventricular Reverse Remodeling in Dilated Cardiomyopathy with Spontaneous Mechanical Alternans.

Objective Spontaneous mechanical alternans (MA), or pulsus alternans, has been observed in heart failure patients with hypertension or tachycardia for 150 years and is considered a sign of a poor prognosis. However, in some dilated cardiomyopathy (DCM) patients with MA, optimal medical therapy (OMT) brings left ventricular reverse remodeling (LVRR), a preferable prognostic indicator. This study examined the probability of LVRR in DCM patients with spontaneous MA and whether or not LVRR can be predicted by the baseline blood pressure or heart rate.

Body fluid regulation via chronic inhibition of sodium-glucose cotransporter-2 in patients with heart failure: a post hoc analysis of the CANDLE trial.

Background: In patients with chronic heart failure (CHF) and type 2 diabetes (T2D), sodium-glucose cotransporter-2 (SGLT2) inhibition improves cardiorenal outcomes, but details of the effects on distinct subsets of body fluid volume remain incomplete.

Methods: This was a post hoc analysis of patients with CHF and T2D in the CANDLE trial (UMIN000017669), an investigator-initiated, multi-center, randomized open-label trial that compared the effect of canagliflozin (100 mg, n = 113) with glimepiride (starting dose: 0.5 mg, n = 120) on changes in N-terminal pro-brain natriuretic peptide.

The Risk of Ventricular Tachyarrhythmias in Patients with Antimitochondrial Antibodies-Related Noncardiac Diseases.

Antimitochondrial antibodies (AMA) are serum autoantibodies specific to primary biliary cholangitis and are linked to myopathy and myocardial damage; however, the presence of AMA as a risk factor for ventricular tachyarrhythmias (VTs) has remained unknown. This study aimed to elucidate whether the presence of AMA-related noncardiac diseases indicates VTs risk.This cohort study enrolled 1,613 patients (883 females) who underwent AMA testing to assess noncardiac diseases.

Long-Term Outcomes in Patients with Not-Retrieval Inferior Vena Cava Filter Under Anticoagulation.

Since permanent inferior vena cava (IVC) filters increase deep vein thrombosis (DVT), filter retrieval should be performed as possible. Despite the guideline recommendation, IVC filters are not always retrieved in clinical practice. To date, many patients with not-retrieval IVC filters have been prescribed anticoagulant therapy, but the long-term prognosis, including venous thromboembolism (VTE) and bleeding events, remains unknown.

Life-threatening ventricular arrhythmia and left ventricular dysfunction associated with anti-mitochondrial antibody-positive myositis: a case report.

Background: Anti-mitochondrial antibody (AMA)-positive myositis is an atypical inflammatory myopathy characterized by chronic progression of muscle atrophy and cardiac involvement. Few detailed reports have shown the clinical course of the cardiac complications of AMA-positive myositis.

Case Summary: A 47-year-old man presented with shortness of breath on exertion.

Transcatheter coil embolization for large pulmonary arteriovenous fistulae through an artificial tricuspid ball valve.

Pulmonary arteriovenous fistulae (PAFs) occur congenitally or are acquired. A PAF can cause hypoxemia, sudden death from rupture, abscess formation, and embolism. Treatment for PAF is transcatheter embolization or surgery.

Incidence and Risk Factors of Future Need for Long-Term Care Insurance in Japanese Elderly Patients With Left Ventricular Systolic Dysfunction.

Background: Heart failure in elderly people causes physical and cognitive dysfunction and often requires long-term care insurance (LTCI); however, among patients with left ventricular (LV) systolic dysfunction, the incidence and risk factors of future LTCI requirements need to be elucidated.

Methods and results: The study included 1,852 patients aged ≥65 years with an echocardiographic LV ejection fraction (LVEF) ≤50%; we referred to their LTCI data and those of 113,038 community-dwelling elderly people. During a mean 1.
