BACKGROUND: The Atrial Fibrillation and Ischemic Events with Rivaroxaban in Patients with Stable Coronary Artery Disease (AFIRE) trial demonstrated non-inferior efficacy endpoints for rivaroxaban monotherapy versus combination therapy (rivaroxaban plus a single antiplatelet) and superior safety endpoints in patients with atrial fibrillation and stable coronary artery disease. AIMS: This post hoc analysis investigated whether the AFIRE trial results reflected the presence or absence of prior revascularisation. METHODS: Among 2,215 patients, 1,697 (76.6%) had previously undergone revascularisation, and the remaining 518 (23.4%) had not undergone prior revascularisation. The primary efficacy endpoint was a composite of stroke, systemic embolism, myocardial infarction, unstable angina requiring revascularisation, or death from any cause, while the primary safety endpoint was major bleeding. RESULTS: In 1,697 patients with prior revascularisation, the efficacy and safety endpoints were superior for monotherapy versus combination therapy (efficacy: hazard ratio [HR] 0.62, 95% confidence interval [CI]: 0.45-0.85; p=0.003; safety: HR 0.62, 95% CI: 0.39-0.98; p=0.042). Among 518 without prior revascularisation, there were no significant differences in endpoints (efficacy: HR 1.19, 95% CI: 0.67-2.12; p=0.554; safety: HR 0.47, 95% CI: 0.18-1.26; p=0.134). There was borderline interaction of the efficacy endpoints (p=0.055) between two treatments. The safety benefit of monotherapy on any bleeding was significant in patients without prior revascularisation (HR 0.59, 95% CI: 0.38-0.93; p=0.022). CONCLUSIONS: In high-risk thrombosis patients with a history of prior revascularisation, rivaroxaban monotherapy versus combination therapy demonstrated favourable safety and efficacy outcomes.

Patients with persistent heart failure (HF) with reduced ejection fraction (HFrEF) have a poorer prognosis than those with HF with improved ejection fraction (HFimpEF). However, data on the predictive value of echocardiographic parameters for persistent HFrEF are lacking. We retrospectively studied 443 patients who were diagnosed with HFrEF (EF ≤ 40%) during hospitalization and underwent echocardiography at the 1-year follow-up. We divided them into the 2 groups: HFimpEF (EF > 40%) and persistent HFrEF group at 1-year follow-up, and assessed the predictive value of echocardiographic parameters at discharge for persistent HFrEF. In total, 301/443 patients (68%) were diagnosed with persistent HFrEF and 142/443 (32%) with HFimpEF at the 1-year follow-up. Kaplan-Meier analysis revealed that the persistent HFrEF group had a poorer prognosis than the HFimpEF group (log-rank, P < 0.001). Receiver operating characteristic curve analysis revealed that left ventricular end-systolic diameter (LVESD) had the highest area under the curve (AUC) (0.70; 95% confidence interval [CI]: 0.64-0.75; cutoff value: 55 mm) among various echocardiographic parameters. LVESD was an independent predictor of persistent HFrEF at the 1-year follow-up (odds ratio: 1.07, 95%CI: 1.02-1.12) upon multivariable logistic regression analysis. The incidence of persistent HFrEF was higher in patients with an LVESD ≥ 55 mm than in those with an LVESD < 55 mm (81% versus 55%, Fisher's exact test, P < 0.001). In conclusion, an LVESD (≥ 55 mm) was associated with persistent HFrEF. Focusing on LVESD in daily practice may help clinicians with risk stratification for decision-making regarding management in patients with advanced HF refractory to guideline-directed medical therapy.

BACKGROUND Heart failure is associated with structural brain abnormalities, including atrophy of multiple brain regions. Previous studies have reported brain atrophy in middle-aged patients with systolic heart failure. In this report, we present the case of a 21-year-old woman with idiopathic dilated cardiomyopathy, cardiac failure, and global cerebral atrophy due to reduced cerebral artery blood flow. We also discuss the impact of brain atrophy in this young adult patient with severe heart failure and no risk factors for atherosclerosis. CASE REPORT A 21-year-old woman with dyspnea and leg edema was admitted to our hospital. After several examinations, an endomyocardial biopsy led to a diagnosis of idiopathic dilated cardiomyopathy, and transthoracic ultrasound cardiography revealed that her left ventricular ejection fraction was 36%. One year after the first hospitalization, her heart failure was classified as New York Heart Association Class III. Magnetic resonance imaging showed severe global brain atrophy, and single-photon emission computed tomography combined with brain computed tomography showed reduced blood flow to the entire brain. She had no risk factors for atherosclerosis and no atherosclerotic changes to her brain or carotid arteries, but her neuropsychological and neurological findings indicated more pronounced brain and cognitive dysfunction. CONCLUSIONS This young adult patient with idiopathic dilated cardiomyopathy, cardiac failure, and global cerebral atrophy showed reduced cerebral artery blood flow and cognitive impairment. The findings of this report indicate that low cardiac output may directly cause brain atrophy in patients with systolic heart failure.

Background Thrombocytopenia poses a risk of bleeding in patients with chronic coronary syndrome after coronary intervention. However, whether thrombocytopenia also increases the bleeding risk in patients with atrial fibrillation and chronic coronary syndrome remains unclear. Methods and Results This study evaluated the AFIRE (Atrial Fibrillation and Ischemic Events With Rivaroxaban in Patients With Stable Coronary Artery Disease) trial. Thrombocytopenia was defined as platelet count <100 000/mm3 level at enrollment. Primary end points included incidence of major bleeding based on the International Society on Thrombosis and Hemostasis criterion and major adverse cardiovascular ischemic events (cardiac death, myocardial infarction, and stroke). A total of 2133 patients were classified into the thrombocytopenia (n=70) and nonthrombocytopenia (n=2063) groups. Major bleeding was significantly higher in the thrombocytopenia group than in the nonthrombocytopenia group (10.0% versus 4.1%, P=0.027). The thrombocytopenia group tended to have a higher risk of major adverse cardiovascular ischemic events (11.4% versus 6.2%, P=0.08). The bleeding incidence was significantly higher in patients with thrombocytopenia receiving combination therapy with rivaroxaban and a single antiplatelet drug (thrombocytopenia group, 14.3%, versus nonthrombocytopenia group, 5.0%; hazard ratio, 3.18 [95% CI, 1.27-7.97], P=0.014). Thrombocytopenia was an independent predictor of major bleeding (hazard ratio, 2.57 [95% CI, 1.19-5.56], P=0.017). Conclusions Among patients with atrial fibrillation and chronic coronary syndrome, thrombocytopenia was significantly associated with increased risk of major bleeding. Selecting drugs for patients with thrombocytopenia continuing antithrombotic therapy should be given special consideration.

The prognosis of tetralogy of Fallot with pulmonary atresia (TOF/PA) is mainly determined by the development of major aorto-pulmonary collateral arteries (MAPCAs) that provide pulmonary blood perfusion. TOF/PA can be managed conservatively until adulthood in patients with adequate, but not excessive perfusion via MAPCAs. To the best of our knowledge, this is the first report of a patient with unrepaired TOF/PA who eventually developed descending aortic dissection (AD), and survived with medical treatment. A 46-year-old woman was referred to our hospital by her local cardiologist with exertional dyspnea. A three-dimensional (3-D) computed tomography (CT) performed prior to presentation showed a dilated thoracic aorta, three well-developed MAPCAs, and a patent ductus arteriosus (PDA), whereas the 3-D CT performed at presentation revealed a descending AD with the entry site at the proximal part of the thoracic descending aorta, and neither the MAPCAs nor the PDA originated from the area of the AD. The patient was treated medically and was discharged thereafter. In this case, 3D-CT taken 9 months prior to the dissection showed no involvement of MAPCAs in the dissection area and was useful to make a decision of conservative therapy. Learning objective: Few systematic studies have addressed patients with tetralogy of Fallot with pulmonary atresia (TOF/PA) who survived more than 20 years due to optimal control of pulmonary blood flow depending on the development of major aorto-pulmonary collateral arteries (MAPCAs). We report a patient with unrepaired TOF/PA who developed descending aortic dissection (AD) in her forties. Three-dimensional computed tomography was useful for diagnosing and choosing a treatment plan by identifying the involvement of MAPCAs within the region of the AD.

An 89-year-old man who had undergone aortic valve replacement with a 21 mm Mosaic bioprosthetic valve at another hospital 14 years ago was admitted to the emergency room for a sudden respiratory distress two days prior and was diagnosed with severe aortic regurgitation( AR) caused by valve insufficiency and acute heart failure secondary to low cardiac function. Upon admission, he was found to have severe hypoxia with PaO2 of 40 mmHg range, and transcatheter aortic valve replacement (TAVI, TAV in SAV) with a 20 mm SAPIEN3 was performed under local anesthesia for fear of hypotension while under general anesthesia. After confirming that AR had completely disappeared, the patient was intubated and discharged from the operating room on a mechanical ventilator. The patient was weaned from the ventilator on the second postoperative day and was transferred to the other hospital for rehabilitation, 48 days postoperatively. Although there is no report on the comparative study of anesthesia methods for emergency transcatheter aortic valve implantation( TAVI), TAVI under regional anesthesia is minimally invasive with a lower risk for hypotension than general anesthesia. Therefore, we believe it is useful for patients with acute heart failure and hypotension. In addition, it is important to use a balloon expandable valve with excellent implantability to complete the procedure in a short time.

BACKGROUND: Despite the advances in the treatment of cardiovascular diseases, effective treatment remains to be established to improve the quality of life and prognosis of patients with chronic coronary syndromes. This study was aimed to evaluate the effectiveness and safety of the low-intensity pulsed ultrasound (LIPUS) therapy, which we have developed as a novel non-invasive angiogenic therapy through upregulation of endothelial nitric oxide synthase (eNOS). METHODS AND FINDINGS: We conducted a randomized, double-blind, placebo-controlled (RCT) pilot trial of the LIPUS therapy for patients with refractory angina pectoris. The patients who received optimal medical therapy without indication of PCI or CABG due to the lack of graftability or complexity of coronary lesions were enrolled. They were randomly divided into the LIPUS treatment group (N = 31) and the placebo group (N = 25) in a 1:1 fashion. The LIPUS therapy was performed in a transthoracic manner for 20 min for 3 sections each (mitral, papillary muscle, and apex levels) under the conditions that we identified; frequency 1.875 MHz, intensity 0.25 MPa, and 32 cycles. The primary endpoint was weekly use of nitroglycerin. Secondary endpoints included stress myocardial perfusion imaging and others. The average weekly nitroglycerin use (times/week) was decreased from 5.50 to 2.44 in the LIPUS group and from 5.94 to 2.83 in the placebo group. The changes in the average weekly nitroglycerin use were comparable; -3.06 (95% CI: -4.481 to -1.648) in the LIPUS group (P<0.01) and -3.10 (95% CI: -4.848 to -1.356) in the placebo group (P<0.01). No adverse effects were noted. CONCLUSIONS: In the present study, the LIPUS therapy did not further ameliorate chest pain as compared with optimal medications alone in patients with refractory angina pectoris. The present findings need to be confirmed in another trial with a large number of patients. (Registration ID: UMIN000012369).

OBJECTIVE: Antithrombotic therapy is essential for patients with atrial fibrillation (AF) and stable coronary artery disease (CAD) because of the high risk of thrombosis, whereas a combination of antiplatelets and anticoagulants is associated with a high risk of bleeding. We sought to develop and validate a machine-learning-based model to predict future adverse events. METHODS: Data from 2215 patients with AF and stable CAD enrolled in the Atrial Fibrillation and Ischaemic Events With Rivaroxaban in Patients With Stable Coronary Artery Disease trial were randomly assigned to the development and validation cohorts. Using the random survival forest (RSF) and Cox regression models, risk scores were developed for net adverse clinical events (NACE) defined as all-cause death, myocardial infarction, stroke or major bleeding. RESULTS: Using variables selected by the Boruta algorithm, RSF and Cox models demonstrated acceptable discrimination and calibration in the validation cohort. Using the variables weighted by HR (age, sex, body mass index, systolic blood pressure, alcohol consumption, creatinine clearance, heart failure, diabetes, antiplatelet use and AF type), an integer-based risk score for NACE was developed and classified patients into three risk groups: low (0-4 points), intermediate (5-8) and high (≥9). In both cohorts, the integer-based risk score performed well, with acceptable discrimination (area under the curve 0.70 and 0.66, respectively) and calibration (p>0.40 for both). Decision curve analysis showed the superior net benefits of the risk score. CONCLUSIONS: This risk score can predict the risk of NACE in patients with AF and stable CAD.

OBJECTIVE: We conducted a prospective observational study to determine the relationship between adherence to continuous positive airway pressure (CPAP) and susceptibility to the common cold in moderate-to-severe obstructive sleep apnea (OSA) patients. METHODS: We prospectively investigated the number of days with common cold symptoms from November 2019 to February 2020. The rate of CPAP use for 4 h/night in the preceding four months (July to October 2019) was used as a measure of CPAP adherence. Multiple generalized linear models were used to evaluate the association to days of common cold symptoms after controlling for demographic variables, habitual short sleep duration, and insomnia severity. RESULTS: We included 123 outpatients (median age 63 years) with moderate-to-severe OSA treated with CPAP. In the multivariate generalized linear model, better CPAP adherence was independently significantly associated with days with fewer common cold symptoms (ß = -0.248, P = 0.031); meanwhile, the severity of insomnia and habitual short sleep duration was not significantly associated with it. Subgroup analyses revealed that the association between CPAP adherence and days with common cold symptoms was also significant in young to middle-aged (<65 years) participants (ß = -0.407, P = 0.005). In contrast, the association was negligible in older (≥65 years) participants. CONCLUSIONS: CPAP adherence may be protective against viral infections in patients with moderate-to-severe OSA. This effect appears to be more pronounced in young to middle-aged patients with OSA.

BACKGROUND: Appropriate implantable cardioverter-defibrillator (ICD) shocks are associated with an increased risk of mortality and heart failure (HF) events. The first appropriate shock may occur late after implantation. However, whether the timing of the first appropriate shock influences prognosis is unknown. This study aimed to evaluate the clinical significance of the timing of the first appropriate shock in patients with ICD. METHODS: This retrospective and observational study enrolled 565 consecutive ICD patients. Patients who received an appropriate shock were divided into the early group (first appropriate shock <1 year after ICD implantation) and late group (first appropriate shock ≥1 year after ICD implantation). All-cause mortality was compared between the two groups. RESULTS: Over a median follow-up of 5.6 years, 112 (19.8%) patients received an appropriate shock, including 32 patients (28.6%) in the early group and 80 patients (71.4%) in the late group. Comparisons of baseline characteristics at ICD implantation revealed that the late group was more likely to receive cardiac resynchronization therapy (66.3% vs. 31.3%, p < 0.001), ICD for primary prevention (60.0% vs. 31.3%, p = 0.001), and angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker treatment (88.8% vs. 71.9%, p = 0.028). Survival after shock was significantly worse in the late group than in the early group (p = 0.027). In multivariable Cox proportional hazards analysis, the late group had an increased risk of all-cause mortality compared with the early group (HR: 2.22; 95% CI 1.01-4.53; p = 0.029). In both groups, the most common cause of death was HF. CONCLUSIONS: Late occurrence of the first appropriate ICD shock was associated with a worse prognosis compared with early occurrence of the first appropriate shock. Cardiac death was the most common cause of death in patients who experienced late occurrence of the first appropriate ICD shock, resulting from HF in most cases.

We evaluated whether modified Model for End-Stage Liver Disease (MELD) scores are useful for predicting the postdischarge prognosis in hospitalized patients with heart failure (HF) who are discharged alive. The MELD-XI and MELD-Na scores were calculated at discharge for a total of 1156 patients in the HIJ-HF II study. We also studied 3 groups on the basis of the left ventricular ejection fraction (LVEF): the HFrEF (LVEF < 40%), HFmrEF (LVEF 40-49%) and HFpEF (LVEF ≥ 50%) groups. The primary outcome was all-cause mortality, and the secondary outcome was rehospitalization due to worsening HF. The median MELD-XI and MELD-Na scores were 12 and 14, respectively. After a median follow-up of 19 months, there were significantly higher rates of all-cause mortality in patients with MELD-XI scores ≥ 12 than in those with MELD-XI scores < 12; there were also higher rates of all-cause mortality in patients with MELD-Na scores ≥ 14 than in those with MELD-Na scores < 14 (both log-rank p < 0.001). The cumulative incidence function based on a competing risks model showed a higher rate of rehospitalization due to worsening HF in patients with MELD-XI scores ≥ 12 than in those with MELD-XI scores < 12 and a higher rate of rehospitalization due to worsening HF in those with MELD-Na scores ≥ 14 than in those with MELD-Na scores < 14 (both Gray's test p < 0.001). The adjusted hazard ratios (HRs) of all-cause mortality for patients with MELD-XI scores ≥ 12 and those with MELD-Na scores ≥ 14 were 2.07 [95% confidence interval (CI) 1.25-3.44] and 2.79 [95% CI 1.63-4.79], respectively, in the HFrEF group; however, the HRs were not significant in the HFmrEF or HFpEF groups. Thus, MELD-XI and MELD-Na scores may be useful for predicting prognosis in hospitalized HF patients who are discharged alive, especially for those in the HFrEF group.

BACKGROUND: Renin-angiotensin system inhibitor (RASi) and ß-blocker provide prognostic benefits as guideline-directed medical therapy (GDMT) in patients with heart failure and reduced ejection fraction (HFrEF). However, there is limited data for the favorable effects in such patients receiving regular hemodialysis. We aimed to evaluate the prognostic impact of RASi and ß-blocker in patients with HFrEF who receive regular hemodialysis. METHODS: In this retrospective, single-center, observational study, from 2110 consecutive patients hospitalized for HF and who survived to discharge, 97 with HFrEF who received regular hemodialysis were included for analysis. They were classified into three groups according to prescribed medication at discharge following index hospitalization: both RASi and ß-blocker (Dual-GDMT group: n = 55), either RASi or ß-blocker (Mono-GDMT group: n = 34), and neither RASi nor ß-blocker (No-GDMT group: n = 8). The primary endpoint was a composite of all-cause death and rehospitalization for heart failure. RESULTS: The mean age was 66 years and 79% of the patients were men. During the median follow-up of 501 days, the primary endpoint occurred in 43 patients (44%). Kaplan-Meier analysis revealed that the Dual-GDMT group had the lowest rates of the primary endpoint (log-rank test for trend: p < 0.001). Even after adjustment for diverse covariates (multivariate Cox regression), the Dual-GDMT (hazard ratio [HR]: 0.04, 95% confidence interval (CI): 0.005-0.32) and Mono-GDMT (HR: 0.08, 95% CI: 0.01-0.50) groups had better prognoses than the No-GDMT group. CONCLUSIONS: The prescription of RASi and/or ß-blocker was associated with a lower adverse-event rate after discharge in patients with HFrEF who were on regular hemodialysis.

BACKGROUND: A recent randomized trial demonstrated that catheter ablation for atrial fibrillation (AF) in patients with heart failure with reduced ejection fraction (EF) is associated with a reduction in death or heart failure. However, the effect of catheter ablation for AF in patients with heart failure with mid-range or preserved EF is unclear.Methods and Results: We screened 899 AF patients (72.4% male, mean age 68.4 years) with heart failure and left ventricular EF ≥40% from 2 Japanese multicenter AF registries: the Atrial Fibrillation registry to Follow the long-teRm Outcomes and use of aNTIcoagulants aftER Ablation (AF Frontier Ablation Registry) as the ablation group (525 patients who underwent ablation) and the Hokuriku-Plus AF Registry as the medical therapy group (374 patients who did not undergo ablation). Propensity score matching was performed in these 2 registries to yield 106 matched patient pairs. The primary endpoint was a composite of cardiovascular death and hospitalization for heart failure. At 24.6 months, the ablation group had a significantly lower incidence of the primary endpoint (hazard ratio 0.32; 95% confidence interval 0.13-0.70; P=0.004) than the medical therapy group. CONCLUSIONS: Compared with medical therapy, catheter ablation for AF in patients with heart failure and mid-range or preserved EF was associated with a significantly lower incidence of cardiovascular death or hospitalization for heart failure.

Atrial fibrillation (AF) ablation can improve left ventricular ejection fraction (LVEF) and renal function and can even reduce mortality in patients with impaired LVEF. However, the effect of post-ablation cardiorenal dysfunction on the prognosis of patients with impaired LVEF who underwent AF ablation remains unclear. Of the 1243 consecutive patients undergoing AF ablation, the prognosis of 163 non-dialysis patients who underwent AF ablation with < 50% LVEF was evaluated. The primary outcome was a composite of all-cause mortality, heart failure hospitalization, and a need for modification of the treatment for heart failure. During the median follow-up of 4.2 years after the first AF ablation procedure, the primary outcome occurred in 30 of 163 patients (18%). The receiver operating characteristic curve analysis demonstrated that the post-LVEF (LVEF within 1 year after the procedure, and before the occurrence of primary outcome) had larger areas under the curve (0.70) than the pre-LVEF (LVEF before the procedure), and the most optimal cutoff value was LVEF ≤ 42%. Multivariate analysis demonstrated that patients with post-LVEF ≤ 42% and worsening renal function (WRF; an absolute increase in serum creatinine [SCr] ≥ 0.3 mg/dL compared with the SCr at baseline within 1 year after the procedure and before the occurrence of primary outcome) had a 3.4- to 4.3-fold and 3.4- to 3.7-fold higher risk of the primary outcome compared with those without these predictors, respectively. Patients were categorized using post-LVEF ≤ 42% and WRF as follows: group 1 (post-LVEF > 42% without WRF), group 2 (post-LVEF ≤ 42% without WRF), group 3 (post-LVEF > 42% with WRF), and group 4 (post-LVEF ≤ 42% with WRF). Group 4 had a 15.8-fold (P = 0.0001) higher risk of the primary outcome compared with group 1 after adjusting for pre-procedural factors. In patients with impaired LVEF undergoing AF ablation, post-LVEF ≤ 42% and WRF were independent predictors of poor prognosis. The combination of post-LVEF ≤ 42% and WRF is strongly associated with a poor prognosis in patients with AF undergoing ablation, who with these post-ablation cardiorenal dysfunction may have to be treated more intensively after AF ablation.

PURPOSE: Several landmark trials have reported that direct oral anticoagulants (DOACs) are more effective in preventing stroke and systemic embolism than vitamin K antagonists. However, nonadherence to DOACs worsens prognosis in patients with nonvalvular atrial fibrillation (NVAF) despite the effectiveness of the drugs. The purpose of this study was to evaluate the effects of a pharmacist-led educational interventional program involving motivational interviewing on medication adherence, as assessed by electronic monitoring, in patients receiving DOACs for the treatment of NVAF. METHODS: This prospective, randomized, interventional study was conducted at outpatient cardiology clinics at general hospitals and pharmacies in Japan. Patients with NVAF who were treated with a once-daily DOAC (edoxaban) or a twice-daily DOAC (apixaban) were randomized to receive either: (1) an educational interventional program involving motivational interviewing regarding adherence to anticoagulants; or (2) standard medication counseling. The primary end point was the change in the medication adherence rate, calculated as the number of days that patients appropriately took the drug, as assessed by an electronic monitoring device, divided by the total number of days that the drug was prescribed, from a 12-week observation period to a 12-week intervention period. The secondary end points were tolerability outcomes. The effect of the educational interventional program on the primary end point was analyzed in subgroups stratified by gender and type of DOAC received. FINDINGS: A total of 268 patients completed the observation period and were randomly assigned to one of the two study groups. The difference in the primary end point between the educational interventional program group and the standard medication counseling group was not significant (mean [SD], 2.9% [7.5%] vs 3.4% [8.3%]). On multiple linear regression analysis, the difference in DOAC adherence between the two groups was not significant, but that adherence to apixaban was significantly improved among men in the educational interventional program (ß = 0.219; P = 0.012). Two patients died of causes considered unrelated to treatment; no stroke/systemic embolism or major bleeding events were observed. IMPLICATIONS: In this randomized, controlled study of the effects of a pharmacist-led educational interventional program using motivational interviewing on adherence to DOACs among patients with NVAF, adherence to DOACs, as assessed using an electronic monitoring device, was not improved with the educational interventional program compared to standard medication counseling . However, adherence to twice-daily apixaban was improved among men, but not among women, in the educational interventional program group. In this study, the selection of DOACs was not randomized, and the lack of assessment of the association between adherence to DOACs and clinical outcomes was a limitation.

INTRODUCTION: Guidelines recommend ventricular rate control to <130 bpm during atrial fibrillation (AF) in patients with acute decompensated heart failure (ADHF) to avoid aggravating deteriorations in cardiac outputs. We aimed to evaluate the prognostic impact of landiolol in patients with ADHF and AF. METHODS: This observational study included 60 patients who were urgently hospitalized with ADHF and presented with AF and a heart rate (HR) ≥130 bpm at admission. The patients were assigned to the landiolol group (n = 37) or the reference group (n = 23) based on their intravenous landiolol use within 24 h after admission. The primary endpoint was death from any cause. RESULTS: The groups' baseline characteristics were similar. A significant HR reduction occurred in the landiolol group at 2 h after admission. Compared with the reference group, the HR was significantly lower (111.6 vs. 97.9 bpm, p = 0.02) and the absolute HR reduction was greater (-32.2 vs. -50.0 bpm, p = 0.006) in the landiolol group at 48 h after admission. The landiolol group's mortality rate was significantly lower than that in the reference group (log-rank test, p = 0.032). landiolol use within 24 h after admission was independently associated with lower all-cause mortality (adjusted hazard ratio: 0.15, 95% confidence interval: 0.02-0.92). CONCLUSION: Patients with ADHF and AF who received landiolol for rate control during the acute phase had better prognoses than those who did not receive landiolol.

Left ventricular (LV) diastolic dysfunction is associated with heart failure with preserved ejection fraction, and metabolic syndrome (MetS) is a risk factor. However, there is limited knowledge regarding the metabolic factors that contribute to LV dysfunction in postmenopausal women without comorbidities. This study aimed to analyze the relationship between LV diastolic dysfunction and MetS, as well as other cardiovascular risk factors, and to determine risks for LV diastolic dysfunction. Postmenopausal women without hypertension, diabetes mellitus, LV systolic dysfunction, or other heart diseases underwent physical examinations, including echocardiography. The study participants were diagnosed with LV diastolic dysfunction based on several echocardiographic parameters. Logistic regression analyses of LV diastolic dysfunction and cardiovascular risk factors were performed. Of the 269 postmenopausal women examined, 29 (10.7%) and 40 (14.9%) had MetS and LV diastolic dysfunction, respectively. Abnormal diastolic blood pressure (odds ratio, 3.6; 95% confidence interval, 1.16-10.9; P < 0.05) and age (odds ratio, 1.1; 95% confidence interval, 1.07-1.19; P < 0.01) were predictors of LV diastolic dysfunction. In healthy postmenopausal women, high-normal diastolic blood pressure was the only independent risk factor for LV diastolic dysfunction, and it thus may be a useful predictor of diastolic heart failure during routine physical examinations.

OBJECTIVE: Rapid eye movement (REM) obstructive sleep apnea (OSA) is associated with the risk of cardiovascular events. Arterial stiffness and carotid artery intima-media thickness (IMT) predict these events, but few relevant studies have been conducted. We compared long-term changes in arterial stiffness and IMT between patients with REM OSA and non-REM (NREM) OSA receiving continuous positive airway pressure (CPAP) or oral appliance (OA) therapy. METHODS: Newly diagnosed female patients with OSA received CPAP (n = 6) or OA (n = 7). Pulse wave velocity (PWV) and carotid artery ultrasound were performed before and 60 months after treatment. RESULTS: There were no differences in baseline characteristics (mean age: 56.0 vs. 61.3 years; mean body mass index: 22.6 vs. 21.7 kg/m2) between the REM OSA and non-REM OSA groups. The median apnea-hypopnea index was lower in the REM OSA group than in the non-REM OSA group. Increased PWV (12.92 ± 1.64 to 14.56 ± 2.73 m/s) and deteriorated glucose metabolism were observed in the REM OSA group after treatment. PWV, IMT, and cardiovascular risk factors were unaffected in the non-REM OSA group. CONCLUSION: Arterial stiffness and glucose metabolism are deteriorated in patients with REM OSA compared with these parameters in patients with non-REM OSA after CPAP or OA treatment.
