Background
Mavacamten, a first-in-class cardiac myosin inhibitor, is approved internationally for the treatment of symptomatic adult patients with obstructive hypertrophic cardiomyopathy (HCM) and has been shown to improve cardiac function and symptoms in adult patients across multiple phase 3 trials. The efficacy and safety of mavacamten in pediatric patients with obstructive HCM has not been evaluated.
Methods
SCOUT-HCM is a phase 3, randomized, placebo-controlled, double-blind, parallel-group, multicenter, international study in symptomatic adolescent patients (12 years to <18 years old) with obstructive HCM. The aim of the study is to assess the efficacy, safety, and pharmacokinetics of mavacamten in this population. Participants will be randomized 1:1 to mavacamten or placebo for 28 weeks, followed by a 28-week active-treatment period (when patients randomized to placebo will cross over to mavacamten) and an open-label long-term extension period for ≤144 weeks. Participants will initiate mavacamten at a dosage of 2.5 mg/day or 5 mg/day; dose titration will be based on echocardiographic assessment of Valsalva left ventricular (LV) outflow tract (LVOT) gradient and LV ejection fraction. The primary endpoint is change from baseline to week 28 in Valsalva LVOT gradient. Secondary endpoints include efficacy parameters of resting and post-exercise LVOT gradients, peak oxygen consumption, symptoms, and health status, plus safety and pharmacokinetic parameters.
Conclusions
SCOUT-HCM is the first clinical trial to evaluate a cardiac myosin inhibitor in adolescent patients with obstructive HCM. SCOUT-HCM will assess the utility of mavacamten in this patient population with an unmet clinical need.

Background
Prophylactic steroids are often used to reduce the systemic inflammatory response to cardiopulmonary bypass in infants undergoing heart surgery. The STRESS trial found that the odds of a worse outcome did not differ between infants randomized to methylprednisolone (n = 599) versus placebo (n = 601) (adjusted odds ratio [OR], 0.86; P = .14). However, secondary analyses showed possible benefits with methylprednisolone. To investigate further using a different probabilistic approach, we re-analyzed the STRESS trial using Bayesian analytics.
Methods
We used a covariate-adjusted proportional odds model using the original STRESS trial primary endpoint, a ranked composite of death, transplant, major complication and post op length of stay. We performed Markov Chain Monte Carlo simulations to assess the probability of benefit (OR < 1) versus harm (OR > 1). Primary analysis assumed a neutral probability of benefit versus harm with weak prior belief strength (nearly noninformative prior distribution). To illustrate magnitude of effect, we calculated predicted risk of death, transplant or major complications for methylprednisolone and placebo. Sensitivity analyses evaluated pessimistic (5%-30% prior likelihood of benefit), neutral and optimistic (70%-95%) prior beliefs, and controlled strength of prior belief as weak (30% variance), moderate (15%) and strong (5%). A secondary analysis derived empirical priors using data from four previous steroid trials.
Results
The posterior probability of any benefit from methylprednisolone was 92% and probability of harm was 8%. Composite death or major complication occurred in 18.8% of subjects with an absolute risk difference of −2% (95% CI −3%, +1%) for methylprednisolone. Each of 9 sensitivity analyses demonstrated greater probability of benefit than harm in the methylprednisolone group with 8 of 9 demonstrating >80% probability of benefit and ≥1% absolute difference in risk of death, transplant or major complications. In secondary analysis deriving priors from previous steroid trials, results were consistent with a 95% posterior probability of benefit.
Conclusion
Our Bayesian re-analysis of the STRESS trial, using a range of prior beliefs, demonstrated a high probability that perioperative methylprednisolone reduces the risk of death or major complications in infants undergoing cardiopulmonary bypass compared with placebo. This more in-depth analysis expands the initial clinical evaluation of methylprednisolone provided by the STRESS trial.
背景：在接受心脏手术的婴儿中，预防性类固醇常被用于减少体外循环的全身炎症反应。STRESS试验发现，随机分配给甲基强的松龙组（n=599）和安慰剂组（n=601）的婴儿出现较差结果的几率没有差异（校正优势比[OR]， 0.86； P=0.14）。然而，二次分析显示甲基强的松龙可能有益处。为了使用不同的概率方法进一步研究，我们使用贝叶斯分析重新分析了STRESS试验。方法：我们使用协变量调整的比例优势模型，采用最初的STRESS试验主要终点，死亡、移植、主要并发症和术后住院时间的排序组合。我们进行了马尔可夫链蒙特卡罗模拟来评估收益的概率（OR 1）。初步分析假设利与弊的概率为中性，先验信念强度较弱（几乎是非信息性先验分布）。为了说明效果的程度，我们计算了甲基强的松龙和安慰剂的预测死亡、移植或主要并发症的风险。敏感性分析评估悲观（5%-30%先验获益可能性）、中性和乐观（70%-95%）先验信念，并将控制先验信念的强度分为弱（30%方差）、中等（15%）和强（5%）。二次分析利用先前四次类固醇试验的数据得出经验先验。结果：甲泼尼龙获益的后验概率为92%，伤害的后验概率为8%。18.8%的受试者发生复合死亡或主要并发症，甲基强的松龙的绝对风险差为-2% （95% CI -3%, +1%）。9项敏感性分析中的每一项都显示甲基强的松龙组的获益概率大于危害概率，其中9项分析中有8项显示获益概率为80%以上，死亡、移植或主要并发症风险的绝对差异≥1%。从先前的类固醇试验中获得先验的二次分析结果与95%的后验获益概率一致。结论：我们使用一系列先验信念对STRESS试验进行贝叶斯再分析，证明与安慰剂相比，围手术期甲基强的松龙降低了接受体外循环的婴儿死亡或主要并发症的风险。这项更深入的分析扩展了STRESS试验提供的甲基强的松龙的初步临床评估。试验注册：Clinicaltrials.gov: NCT03229538 （https://clinicaltrials.gov/study/NCT03229538）。

Background
Clinical guidelines advocate use of validated risk models in patients experiencing heart failure with reduced ejection fraction (HFrEF) to inform prognosis and assist with management. We developed models for worsening HF (WHF) hospitalizations and death within 1 year of incident HFrEF using data available within electronic health records (EHR).
Methods
Adults with incident HFrEF were identified from 2013 to 2022 within an integrated healthcare delivery system. We developed decision tree-based models to estimate risks of WHF hospitalization and death within 1 year of the incident HFrEF date. WHF hospitalizations were ascertained using validated natural language processing algorithms. We evaluated the models using cross-validation and measured final performance (i.e., model discrimination using area under the curve [AUC] and model calibration using the Brier score and calibration plots) on a contemporary hold-out test set of patients from 2021 to 2022.
Results
Among 28,292 adults with incident HFrEF, 17.3% experienced WHF hospitalization and 15.1% all-cause death at 1 year of follow-up. We observed an AUC of 0.698 (95% CI: 0.682-0.714) for WHF hospitalization and 0.849 (95% CI: 0.836-0.861) for death and calibrated with a wide range of predicted risks. In comparison, a claims-based risk score displayed an AUC of 0.577 (95% CI: 0.570-0.606) for WHF hospitalization and a smaller dynamic range. Of patients classified as high risk for WHF hospitalization, only 12.0% were receiving full guideline-directed medical therapy at 6 months after HFrEF diagnosis.
Conclusion
Risk models derived using EHR-based data elements can predict both 1-year WHF hospitalization and all-cause mortality in adults with incident HFrEF more accurately than claims-based approaches. These models can be used to improve population management and better target personalized strategies of care.

Background
Lifestyle modification is a key pillar of atrial fibrillation (AF) management. Yoga has beneficial effects on cardiovascular health and has shown promise as an intervention in AF. However, randomized data are absent.
Objectives
To determine the effect of regular yoga on AF episodes and AF burden in people with paroxysmal or persistent AF over a 12-month period.
Methods
This is a randomized control trial of a yoga program in addition to standard care, compared to standard care alone in people with paroxysmal or persistent AF undergoing a rhythm control management strategy. 222 participants will be randomized 1:1 to the yoga intervention or control. Yoga will be conducted in studio and online with a target of at least 3 classes/week. Controls will be instructed to exercise for at least 150 minutes/week. Rhythm monitoring will be with implantable loop recorder, or ECG capable smartwatch with AF detection and twice daily ECGs. Autonomic metrics will be assessed in the laboratory by HRV, blood pressure variability and direct recordings of muscle sympathetic nerve activity. Following a 3-month training period, the dual primary endpoints of AF recurrence (time to recurrence, as defined by any sustained atrial tachyarrhythmia lasting >1 hour) and AF burden will be determined at 12 months.
Conclusions
This study aims to determine the impact of yoga on AF recurrence and burden in people with paroxysmal and persistent AF. Yoga may provide an effective noninvasive, nonpharmacologic lifestyle strategy in the management of AF.
Trial Registration
The trial was preregistered with the Australian New Zealand Clinical Trials Registry (ACTRN12624000264583).

Real-world characteristics and outcomes in patients with heart failure (HF) and reduced ejection fraction (HFrEF) treated with vericiguat remain unclear. We investigated patient characteristics, hypotension—the most relevant clinical event—, and outcomes after initiating vericiguat in patients with HFrEF.
Methods
In this nationwide, multicentre retrospective study involving 22 hospitals in Japan, we examined symptomatic or asymptomatic hypotension and drug discontinuation within 90 days after initiation of vericiguat in patients with left ventricular ejection fraction <45%. The association between hypotension and HF outcomes was also examined.
Results
Among the 799 patients with HFrEF, the mean age was 69.6 years, and 218 (27.3%) were female. Of them, 316 (39.5%) had New York Heart Association classification III or IV, and 329 (41.8%) had systolic blood pressure (sBP) <100 mm Hg. Hypotension was observed in 25.3% of patients within 90 days, with asymptomatic hypotension being the most common (17.9%). By contrast, drug discontinuation related to hypotension was less frequent (4.4%). After adjustment, sBP <100 mm Hg, low body mass index, and in-hospital vericiguat initiation were associated with the incidence of hypotension within 90 days. Patients who experienced hypotension had a greater risk of cardiovascular death or HF hospitalization than those who did not (P = .01).
Conclusions
Although hypotension was relatively common soon after starting vericiguat, they were not often associated with drug discontinuation. Patients experiencing hypotension had a greater risk of HF outcomes, but this would be primarily associated with their vulnerability, given the infrequent discontinuation.

Background
Excessive aortic cusp calcification increases the risk of periprocedural complications after transcatheter aortic valve replacement (TAVR). Differences in device performance in patients with excessive calcification may affect long-term clinical outcomes.
Objectives
To compare periprocedural and long-term outcomes between self-expanding (SEV) and balloon-expandable (BEV) prostheses in patients with excess cusp calcification undergoing TAVR.
Methods
Consecutive patients with severe aortic stenosis and aortic valve complex calcium volume ≥235 mm³ (on contrast images with Hounsfield unit threshold of 850) who underwent TAVR with either CoreValve/Evolut SEV or SAPIEN BEV from August 2007 to June 2023 were included from a prospective-single center registry. A 1:1 propensity-matched analysis was performed to account for baseline differences between groups.
Results
Among 1,345 patients with excessive cusp calcification undergoing TAVR, 271 matched pairs were identified. Procedural success was achieved in >85% of patients with no difference between groups. Annular rupture occurred more frequently with BEV compared to SEV (2.2% vs 0%, P = .030). SEV had a lower transprosthetic gradient (8.0 mmHg vs 11.2 mmHg, P < .001) but higher rates of mild or greater paravalvular regurgitation (69.7% vs 58.1%, P = .008) and new permanent pacemaker implantation (22.6% vs 15.5%, P = .001). At 5 years, there was no statistically significant difference in mortality between groups (45.1% vs 50.2%, P = .173).
Conclusions
In patients with excessive leaflet calcification undergoing TAVR, BEV had a higher risk of annular rupture, but a lower risk of paravalvular regurgitation, and a lower risk of permanent pacemaker implantation compared to SEV. Mortality was comparable between SEV and BEV throughout 5 years of follow-up.

背景：主动脉尖过度钙化增加经导管主动脉瓣置换术（TAVR）后围手术期并发症的风险。过度钙化患者的器械性能差异可能影响长期临床结果。目的：比较自扩式（SEV）和球囊可扩式（BEV）假体在TAVR中治疗牙尖钙化过度患者的围术期和远期疗效。方法：从2007年8月至2023年6月，采用CoreValve/Evolut SEV或SAPIEN BEV进行TAVR的严重主动脉瓣狭窄和主动脉瓣复合钙容量≥235 mm³（Hounsfield单位阈值850）的连续患者纳入前瞻性单中心登记。进行1:1倾向匹配分析，以解释各组之间的基线差异。结果：在1345例患者中，鉴定出271对配对。85%的患者手术成功，组间无差异。与SEV相比，BEV的环空破裂发生率更高（2.2% vs 0%, p=0.030）。结论：在接受TAVR的小叶过度钙化的患者中，BEV与SEV相比有更高的环破裂风险，但瓣旁反流的风险较低，永久性起搏器植入的风险较低。在5年的随访中，SEV和BEV的死亡率具有可比性。临床试验注册：https://www.Clinicaltrials: gov.

We investigated whether cumulative fasting glucose (FG) and insulin resistance (IR) over 20 years are associated with midlife cardiac dysfunction in young adults with or without type 2 diabetes (T2D)/prediabetes. We included young adults with T2D/prediabetes (N = 279) and matched euglycemic individuals (N = 514) who had repeated measures of fasting glucose (FG) and insulin resistance (IR) and echocardiography assessment from the Coronary Artery Risk Development in Young Adults study (CARDIA). We found that cumulative hyperglycemia is associated with midlife diastolic dysfunction in patients with early-onset T2D, and sustained IR negatively affects systolic and diastolic function regardless of T2D status.

Background
Adult cancer survivors are at increased risk of heart failure (HF) due to standard risk factors and cancer treatment-related cardiac dysfunction. However, the prevalence and treatment of subclinical/stage B heart failure (SBHF) in this population are not well defined.
Objectives
The REDEEM (Risk-guided Disease managEment plan to prevEnt heart failure in patients treated with previous cardiotoxic cancer treatMents) trial will evaluate HF screening and targeted intervention in long-term cancer survivors.
Methods
Survivors ≥40 years old, ≥5 years post potentially-cardiotoxic therapy, and with ≥1 HF risk factor were screened by echocardiography for SBHF (abnormal global longitudinal shortening [GLS], left ventricular hypertrophy [LVH], diastolic dysfunction or abnormal 3-dimensional left ventricular ejection fraction [3D-LVEF]). Those with SBHF were randomized to multidisciplinary cardio-oncology disease management plan (CO-DMP), including neurohormonal blockade, exercise training and risk factor optimization, or usual care. The primary endpoint is change in cardiorespiratory fitness (VO2peak) over 6 months.
Results
Of 1,124 survivors screened, 604 underwent echocardiography, and 145 (24%) had SBHF (age 68±18 years; 81% women). Of those eligible for randomization, 64% had breast cancer and 35% had hematological malignancy. Although baseline 3D-LVEF was preserved (52.8 ± 6.8%), subclinical LV dysfunction was common (GLS 15.6 ± 2.1%) and 39% had evidence of functional impairment (VO2peak≤18ml/kg/min−1). Abnormal GLS was associated with age, BMI, diabetes and anthracycline exposure, whereas functional impairment was only associated with age. Abnormal GLS and functional impairment were not significantly associated (OR 0.90 [95% CI 0.72–1.11], P = .360).
Conclusions
Risk-based screening can identify a high-risk subpopulation of cancer survivors with SBHF.
