Background and Aims The efficacy and safety of early sacubitril/valsartan (Sac/Val) initiation after acute heart failure (AHF) has not been demonstrated outside North America. The present study aimed to evaluate the effect of in-hospital Sac/Val therapy initiation after an AHF episode on N-terminal pro-B-type natriuretic peptide (NT-proBNP) level in Japanese patients. Methods This was an investigator-initiated, multicentre, prospective, randomized, open-label, blinded-endpoint pragmatic trial. After haemodynamic stabilization within 7 days after hospitalization, eligible inpatients were allocated to switch from angiotensin-converting enzyme inhibitor or angiotensin receptor blocker to Sac/Val (Sac/Val group) or to continue angiotensin-converting enzyme inhibitor or angiotensin receptor blocker (control group). The primary efficacy endpoint was the 8-week proportional change in geometric means of NT-proBNP levels. Results A total of 400 patients were equally randomized, and 376 (median age 75 years, 31.9% women, de novo heart failure rate 55.6%, and median left ventricular ejection fraction 37%) were analysed. The per cent changes in NT-proBNP level geometric means at Weeks 4/8 were −35%/−45% (Sac/Val group) and −18%/−32% (control group), and their group ratio (Sac/Val vs. control) was 0.80 (95% confidence interval 0.68–0.94; P =.008) at Week 4 and 0.81 (95% confidence interval 0.68–0.95; P =.012) at Week 8, respectively. In the pre-specified subgroup analyses, the effects of Sac/Val were confined to patients with a left ventricular ejection fraction < 40% and were more evident in those in sinus rhythm and taking mineralocorticoid receptor antagonists. No adverse safety signal was evident. Conclusions In-hospital Sac/Val therapy initiation in addition to contemporary recommended therapy triggered a greater NT-proBNP level reduction in Japanese patients hospitalized for AHF. These findings may expand the evidence on Sac/Val therapy in this clinical situation outside North America.

- Abstract
n-3 polyunsaturated fatty acids (PUFAs) reduce the risk of ischemic heart disease. However, there are few reports of a relationship between n-3 PUFAs and coronary spastic angina (CSA). This study aimed to assess the age-dependent role of serum levels of fatty acid in patients with CSA. We enrolled 406 patients who underwent ergonovine tolerance test (ETT) during coronary angiography for evaluation of CSA. All ETT-positive subjects were diagnosed as having CSA. We categorized the patients by age and results of ETT as follows: (1) young (age ≤ 65 years) CSA-positive (n = 32), (2) young CSA-negative (n = 134), (3) elderly (age > 66 years) CSA-positive (n = 36), and (4) elderly CSA-negative (n = 204) groups. We evaluated the serum levels of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), arachidonic acid, and dihomo-gamma-linolenic acid. In the young groups, the serum levels of EPA (64.3 ± 37.7 μg/mL vs. 49.4 ± 28.8 μg/mL, p = 0.015) and DHA (135.7 ± 47.6 μg/mL vs. 117.4 ± 37.6 μg/mL, p = 0.020) were significantly higher in the CSA-positive group than in the CSA-negative group, respectively. However, this was not the case with elderly groups. In the multivariate analysis in young groups, the serum levels of EPA (p = 0.028) and DHA (p = 0.049) were independently associated with the presence of CSA, respectively. Our results suggested that the higher serum levels of EPA and/or DHA might be involved in the pathophysiology of CSA in the young population but not in the elderly population. [Display omitted] • n-3 polyunsaturated fatty acids (PUFAs) may affect coronary spastic angina (CSA). • Age differences influenced the relationship between the development of CSA and PUFAs. • N-3 PUFAs, eicosapentaenoic acid and docosahexaenoic acid, affected the development of CSA in younger patients.

- Abstract
Background: The outcome of catheter ablation could probably differ among patients with atrial fibrillation (AF), depending on age and AF type. We aimed to investigate the difference in predictors of outcome after catheter ablation for AF among the patient categories divided by age and AF type. Methods and Results: A total of 396 patients with AF (mean age 65.69 ± 11.05 years, 111 women [28.0%]) who underwent catheter ablation from January 2018 to December 2019 were retrospectively analyzed. We divided the patients into four categories: patients with paroxysmal AF (PAF) or persistent AF (PeAF) who were 75 years or younger (≤75 years) or older than 75 years (>75 years). Kaplan–Meier survival analysis demonstrated that patients with PAF aged ≤75 years had the lowest AF recurrence among the four groups (log‐rank test, p =.0103). In the patients with PAF aged ≤75 years (N = 186, 46.7%), significant factors associated with recurrence were female sex (p =.008) and diabetes (p =.042). In the patients with PeAF aged ≤75 years (N = 142, 35.9%), the only significant factor associated with no recurrence was medication with a renin‐angiotensin system inhibitor (p =.044). In the patients with PAF aged >75 years (N = 53, 14.4%), diabetes was significantly associated with AF recurrence (p =.021). No significant parameters were found in the patients with PeAF aged >75 years (N = 15, 4.1%). Conclusions: Our findings indicate that the risk factors for AF recurrence after catheter ablation differed by age and AF type. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to determine possible associations between sarcopenia and poor cardiovascular outcomes in patients with chronic heart failure after cardiac resynchronization therapy. Methods: This retrospective study evaluated 120 patients who underwent cardiac resynchronization therapy between March 2004 and June 2018. In total, 58 patients who underwent computed tomography within 30 days of cardiac resynchronization therapy implantation were eligible for inclusion, and their data were analyzed (25 women; 33 men; mean age 71.6 ± 8.7 years). Skeletal muscle area was measured at the third lumbar vertebra, and skeletal muscle index was calculated. Major adverse cardiovascular events included cardiovascular death, hospitalization due to heart failure, cerebral infarction, acute myocardial infarction and cardiac arrest. Results: During the follow‐up period (mean 868 ± 617 days), major adverse cardiovascular events occurred in 22 of 58 patients (38%). The patients were allocated to two groups according to sex‐based tertiles of skeletal muscle index. The lowest tertile was defined as the low skeletal muscle index group. Kaplan–Meier survival analysis showed that the low skeletal muscle index group had a higher incidence of major adverse cardiovascular events (log‐rank 4.38; P = 0.036). Cox proportional hazards regression analysis also showed that low skeletal muscle index values were significantly associated with major adverse cardiovascular events (hazard ratio 3.08; 95% confidence interval 1.26–7.66, P = 0.014). Conclusions: Decreases in skeletal mass index on computed tomography might predict the occurrence of major adverse cardiovascular events in patients with chronic heart failure who underwent cardiac resynchronization therapy.

MITRAL valve insufficiency ,HEART failure ,MITRAL valve ,SARCOIDOSIS - Abstract
A 70‐year‐old woman who had cardiac sarcoidosis and severe tethering mitral regurgitation (MR) and had been implanted with a biventricular pacemaker experienced recurrent hospitalisation due to decompensated heart failure (HF). Application of MultiPoint™ pacing reduced the MR volume and maintained the symptoms under control; however, the predicted longevity of the device significantly decreased because of the very high threshold of the added pacing site. Transcatheter mitral valve repair (TMVR) using MitraClip® was performed to further diminish the severe MR, thereby enabling the switch from highly consumptive multipoint pacing (MPP) to energy‐saving single‐point pacing. MPP could further reduce MR compared to the conventional single‐point pacing, and this could be a bridging therapy to TMVR in some patients implanted with a biventricular pacemaker. This is the first case to report that switching from conventional single‐point pacing to MPP decreased the MR, to some extent, resulting in the improvement of HF symptoms. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Variant angina (VA) is caused by reversible coronary artery spasm, which is characterized by chest pain with ST‐segment elevations on standard 12‐lead electrocardiogram (ECG) at rest. Ventricular fibrillation (VF) is often caused by VA attack, but the risk stratification is not well understood. The purpose of this study was to evaluate the impact of fragmented QRS (fQRS) on VF occurrence in VA patients. Methods: Ninety‐four patients who showed ST elevation on 12‐lead ECGs with total or nearly total occlusion in response to coronary spasm provocation test were enrolled. Among them, 16 patients had documented VF before hospital admission (n = 12) or experienced VF during provocation test (n = 4) (VF occurrence group). The fQRS was defined as the presence of spikes within the QRS complex of two or more consecutive leads. Results: The prevalence of fQRS was more often observed in the VF occurrence group than in the non‐VF occurrence group (63% [10/16] vs. 27% [21/78], p = 0.009). Univariate analyses revealed that age, history of syncope, QTc, and the presence of fQRS were associated with VF occurrence (p = 0.004, 0.005, 0.029, and 0.008, respectively). Furthermore, upon multivariate analyses using those risk factors, age, QTc, and fQRS predicted VF occurrence independently (p = 0.007, 0.041, and 0.014, respectively). Conclusions: The present study demonstrated that fQRS in VA patients is a risk factor for VF. The fQRS may be a useful factor for the risk stratification of VF occurrence in VA patients.

HEART failure patients ,PATIENT readmissions - Abstract
We present a 66‐year‐old male patient with heart failure, mid‐range ejection fraction and QRS widening suffering from recurrent hospitalization due to acute heart failure. We measured intra‐cardiac pressure by cardiac catheterization to clearly demonstrate the augmentation of afterload by a vasoconstricting drug induced increase of left ventricular end‐diastolic blood pressure and pulmonary capillary wedge pressure with pulmonary arterial V‐wave augmentation (indicator of worsening of mitral regurgitation). Because the patient was considered as refractory to optimal medication, cardiac resynchronization therapy (CRT) was performed. After CRT implantation, these factors were improved, and the patient has not experienced recurrent hospitalization for >2 years. [ABSTRACT FROM AUTHOR]

Overall mortality and neurologic outcome of patients treated by veno-arterial extracorporeal membrane oxygenation (V-A ECMO) was still not satisfactory. The aim of this study was to clarify the determinants of survival and favorable neurologic outcomes in patients with ischemic heart disease (IHD) treated by V-A ECMO. We identified IHD patients who received V-A ECMO, and divided those patients into the survived and the in-hospital death group. Multivariate logistic regression analysis was performed to identify the determinants of survival and favorable neurologic outcomes. Fifty-eight patients were divided into the in-hospital death group ( n = 35) and the survived group ( n = 23). Cardiogenic arrest for the reason for V-A ECMO introduction (vs. non-cardiac arrest: OR 0.34, 95% CI 0.002-0.65, P = 0.03) and final thrombolysis in myocardial infarction (TIMI-3) flow grade (vs. TIMI ≤2 flow grade: OR 17.44, 95% CI 1.65-184.04, P = 0.02) were determinants of in-hospital survival. Time from collapse to initiation of V-A ECMO was inversely associated with favorable neurologic function (10 min increase; OR 0.49, 95% CI 0.28-0.89, P = 0.02), while final TIMI-3 flow grade was not associated with favorable neurologic function. In conclusion, the rapid establishment of V-A ECMO system as well as obtaining TIMI-3 flow grade should be sought for better survival with maintaining neurological function in IHD patients who requires V-A ECMO.
