Background

Early identification of the one in five patients readmitted within 30 days of an acute myocardial infarction (AMI) hospitalisation provides an opportunity for targeted proactive intervention thereby reducing the risk of readmission. To target such an intervention to those most likely to benefit, this study sought to develop and validate a model predicting 30-day, all-cause, unplanned readmission after hospitalisation for AMI.

Methods

The index AMI encounter for patients undergoing acute coronary angiography between 2012 and 2022 enrolled into the CADOSA (Coronary Angiogram Database of South Australia) Registry and discharged home across four tertiary hospitals were included. A random split sample of 70% and 30% was used for the derivation and validation cohorts, respectively. Logistic regression with combination elimination was performed to develop the parsimonious clinical model within the derivation cohort and model discrimination was assessed in the validation cohort.

Results

Among 13,289 unique patients (mean age 64±13 years, 71% male, 41% ST-elevation AMIs), 14.2% were readmitted within 30 days. Readmitted patients were older (67±14 vs 63±13; p<0.001) and less likely to present with a ST-elevation AMI (38% vs 42%; p=0.003). Predictors showing a higher likelihood of readmission were patients with abnormal estimated glomerular filtration rate, cardiogenic shock and increased heart rate upon arrival, new diagnosis of heart failure, being older and female, and a history of depression. The model had consistent moderate discrimination (C statistic=0.63 in the derivation and validation cohorts).

Conclusions

An Australian model for 30-day all-cause unplanned readmission has a similar performance to United States models. Further emphasis should be placed on providing additional support to high-risk patients upon arrival to the hospital to assist in reducing readmissions.
背景:早期识别五分之一的急性心肌梗死(AMI)住院30天内再入院的患者为有针对性的主动干预提供了机会,从而降低了再入院的风险。为了将这种干预措施针对那些最有可能受益的人,本研究试图开发并验证一个模型,预测AMI住院后30天的全因意外再入院。方法:纳入2012年至2022年在CADOSA (South Australia冠状动脉造影数据库)登记处登记并出院的四家三级医院的急性冠状动脉造影患者的AMI指数。推导组和验证组分别采用70%和30%的随机抽样。在衍生队列中采用联合剔除的逻辑回归建立简约临床模型,并在验证队列中评估模型判别性。结果:在13289例特殊患者中(平均年龄64±13岁,71%为男性,41%为st段抬高ami), 14.2%的患者在30天内再次入院。再入院患者年龄较大(67±14 vs 63±13)。结论:澳大利亚30天全因非计划再入院模型与美国模型具有相似的表现。应进一步强调在高危患者抵达医院时提供额外支持,以协助减少再入院。

Background

After cardiac surgery including median sternotomy, patients are often advised to restrict upper limb activity, lifting, and weight bearing to reduce the risk of wound dehiscence and sternal instability. “Keep Your Move in the Tube” (KMIT) is an evidence-based strategy developed for patients after a sternotomy for cardiac surgery that promotes early resumption of functional activities using biomechanical principles. To date, there is inconsistency of KMIT implementation to improve patient recovery and outcomes. The application of a knowledge translation approach may facilitate the transformation in practice required.
The aims of this study were to conduct a review of current practice, with a focus on exercise for patients after median sternotomy in public acute surgical and cardiac rehabilitation programs in Australia and assess the implementation of KMIT using the Knowledge to Action framework.

Method

This prospective, longitudinal, observational study used a RE-AIM framework for assessment. The project was undertaken in four main phases; i) a survey to assess cardiac rehabilitation practice, ii) development and codesign of an implementation strategy to standardise education and exercise training, iii) implementation, and iv) assessment of the implementation strategy between December 2021 and June 2024.

Results

The survey found lifting and weight bearing advice and exercise provided to patients after a sternotomy for cardiac surgery was inconsistent across the included cardiac rehabilitation programs. The results of the education delivered by 12 local change champions and attended by 390 clinicians demonstrated an improvement in KMIT familiarity from 11% to 76%. A total of 82% reported integrating KMIT principles into usual clinical practice, an increase from 23% at baseline. At follow-up, 82% of respondents reported that KMIT was embedded as clinical practice. Despite a comprehensive education and training strategy, a systematic implementation using a structured framework and high levels of adoption, uncertainty remained about load and time restrictions after a sternotomy, highlighting a need for strategies which focus on the key principles of KMIT and their implications for functional tasks and exercise.

Conclusions

Using a structured process to codesign, develop, and implement a bespoke education and training intervention, KMIT was successfully adopted across cardiac rehabilitation programs within a large health service. This study has also identified opportunities for future improvements and strategies to promote consistency translation and sustainability.
背景:在包括胸骨正中切开术在内的心脏手术后,通常建议患者限制上肢活动、举重和负重,以减少伤口裂开和胸骨不稳定的风险。“Keep Your Move in the Tube”(KMIT)是一种基于证据的策略,用于心脏手术胸骨切开术后患者,利用生物力学原理促进功能活动的早期恢复。迄今为止,KMIT的实施在改善患者康复和预后方面存在不一致性。知识翻译方法的应用可以促进实践中所需的转换。本研究的目的是对目前的实践进行回顾,重点关注澳大利亚公共急性外科和心脏康复项目中胸骨正中切开术后患者的运动,并使用知识到行动框架评估KMIT的实施情况。方法:这项前瞻性、纵向、观察性研究使用RE-AIM框架进行评估。该项目分四个主要阶段进行;i)评估心脏康复实践的调查,ii)制定和共同设计标准化教育和运动训练的实施策略,iii)实施,以及iv)评估2021年12月至2024年6月期间的实施策略。结果:调查发现,在包括的心脏康复项目中,对胸骨切开术后患者提供的举重和负重建议和锻炼不一致。由12名当地变革倡导者和390名临床医生参加的教育结果表明,对KMIT的熟悉程度从11%提高到76%。共有82%的人报告将KMIT原则纳入常规临床实践,比基线时的23%有所增加。在随访中,82%的应答者报告KMIT被纳入临床实践。尽管有一个全面的教育和培训策略,一个使用结构化框架和高水平采用的系统实施,在胸骨切开术后的负荷和时间限制方面仍然存在不确定性,强调需要关注KMIT的关键原则及其对功能任务和锻炼的影响的策略。结论:使用结构化的过程来共同设计、开发和实施定制的教育和培训干预,KMIT成功地应用于大型医疗服务机构的心脏康复项目。这项研究还确定了未来改进的机会和促进一致性、翻译和可持续性的战略。

Background

The management of patients with severe asymptomatic aortic regurgitation remains controversial. This systematic review and meta-analysis aimed to assess and compare long-term outcomes between early surgery and conventional treatment (CT) for severe asymptomatic aortic regurgitation in patients with preserved left ventricular systolic function.

Method

We conducted a systematic search in the EMBASE, PubMed, and Cochrane databases for studies comparing early surgery with CT. The analysed outcome was death from all causes. We evaluated the risk of bias in the included studies using the ROBINS-I (Risk Of Bias In Non-randomised Studies of Interventions) tool.

Results

Three studies, involving 469 patients, were included. Of the participants studied, 57% underwent early surgery, and 43% underwent CT. Early surgery did significantly reduce all-cause mortality (odds ratio 0.35; 95% confidence interval 0.12–1.00; p=0.05; I2=54%).

Conclusions

Our study provides evidence supporting the idea that early surgery, in comparison to conservative management, is associated with better long-term outcomes in patients with severe asymptomatic aortic regurgitation and normal ventricular function.
背景:严重无症状主动脉瓣反流患者的处理仍然存在争议。本系统综述和荟萃分析旨在评估和比较早期手术和常规治疗(CT)对保留左心室收缩功能的严重无症状主动脉瓣返流患者的长期预后。方法:我们在EMBASE、PubMed和Cochrane数据库中进行了系统检索,以比较早期手术与CT的研究。分析结果为全因死亡。我们使用ROBINS-I(非随机干预研究的偏倚风险)工具评估纳入研究的偏倚风险。结果:纳入3项研究,共纳入469例患者。在研究的参与者中,57%的人接受了早期手术,43%的人接受了CT。早期手术显著降低了全因死亡率(优势比0.35;95%可信区间0.12-1.00;p=0.05; I2=54%)。结论:我们的研究提供了证据支持这样一种观点,即与保守治疗相比,早期手术与严重无症状主动脉瓣反流和心室功能正常的患者有更好的长期预后。

Background

Heart failure with reduced ejection fraction (HFrEF) is one of the most prevalent chronic cardiac conditions. Despite recent advances, overall morbidity and mortality remain high. Routine outpatient evaluation is predominantly based on subjective descriptions of symptoms. The utility of non-invasively obtained haemodynamic parameters in identifying high-risk patients with HFrEF has not been described.

Methods

Clinically stable (>3 months) patients with HFrEF from the tertiary HF clinic at St. Boniface Hospital, Canada were recruited. Resting and exercise-augmented (25 watts, up to 12 minutes on a mounted bike) haemodynamic parameters were obtained using a Non-Invasive Cardiac System (NICaS), a whole-body impedance cardiography-based technology. Electronic patient records were reviewed to identify outcomes.

Results

Overall, 63 patients (63.4±15.4 years; 11 [17.5%] female, mean body mass index 31.0±7.1 kg/m2) were recruited. Resting stroke index (SI) correlated with post-exercise SI (r=0.56). At 12-month follow-up, 25 of 63 subjects (39.7%) experienced adverse outcomes (emergency department presentation or unplanned HF hospitalisation, new-onset arrhythmia, referral for cardiac implantable electronic device implantation/optimisation, referral for palliative care and all-cause death). Lower resting SI, either supine (35.5±9.5 vs 40.3±8.0 mL/m2; p=0.02) or sitting (32.1±7.9 vs 37.6±7.9 mL/m2; p=0.009) and exaggerated exercise-augmented Granov–Goor index, a surrogate marker of impaired left ventricular contractility, were the hemodynamic parameters most strongly associated with outcomes.

Conclusions

Non-invasively obtained resting SI and higher exercise-augmented Granov–Goor index identify a high-risk cohort among patients with clinically stable HFrEF. Such findings should be validated in a larger prospective study.
背景:心力衰竭伴射血分数降低(HFrEF)是最常见的慢性心脏疾病之一。尽管最近取得了进展,但总体发病率和死亡率仍然很高。常规门诊评估主要基于对症状的主观描述。非侵入性获得的血流动力学参数在识别HFrEF高危患者中的应用尚未被描述。方法:招募来自加拿大St. Boniface医院三级HF门诊的临床稳定(bb0 ~ 3个月)HFrEF患者。静息和运动增强(25瓦,骑自行车12分钟)血液动力学参数使用无创心脏系统(NICaS),一种基于全身阻抗心动图的技术。检查电子病历以确定结果。结果:共纳入63例患者(63.4±15.4岁),女性11例(17.5%),平均体重指数31.0±7.1 kg/m2。静息卒中指数(SI)与运动后SI相关(r=0.56)。在12个月的随访中,63名受试者中有25名(39.7%)出现了不良结果(急诊科就诊或计划外心衰住院、新发心律失常、转诊心脏植入式电子装置植入/优化、转诊姑息治疗和全因死亡)。较低的静息SI,无论是仰卧位(35.5±9.5 vs 40.3±8.0 mL/m2, p=0.02)还是坐位(32.1±7.9 vs 37.6±7.9 mL/m2, p=0.009)和运动增强的Granov-Goor指数(左心室收缩功能受损的替代指标)是与结果最密切相关的血流动力学参数。结论:无创获得的静息SI和较高的运动增强Granov-Goor指数可识别临床稳定HFrEF患者中的高危队列。这些发现应该在更大的前瞻性研究中得到验证。

Background

The Perceval bioprosthesis is a contemporary sutureless technology utilised for surgical aortic valve replacement (AVR). Perceval valves allow for AVR with reduced cross-clamp and cardiopulmonary bypass times, which correlates with improved postoperative patient morbidity and mortality. However, there is a paucity of literature reporting the medium-term outcomes from Perceval AVR in New Zealand. We aimed to investigate the mid-term outcomes from Perceval AVR at our single centre.

Method

All consecutive patients undergoing Perceval AVR (during isolated or combined procedures) at our unit from March 2011 to August 2021 were retrospectively analysed from a prospectively-collected database.

Results

Across the 10-year study period, 145 patients (mean age: 73.2 years; males: 71.7%; mean EuroSCORE II: 3.78%) underwent Perceval AVR. The most common indication for surgery was aortic stenosis (82.5%). The operative caseload was complex, with only 27.6% of patients undergoing first-time isolated AVR. The mean crossclamp and cardiopulmonary bypass times were 74.7±40.6 and 111.3±63.6 minutes respectively. Latest follow-up transthoracic echocardiography (performed at a mean of 2.2±1.7 years postoperatively) revealed that 96% of patients had either none or only trivial paravalvular/transvalvular leaks. The 30-day mortality and stroke rates were 6.2% and 2.1% respectively. Medium-term survival rates across 5-year and 9.5-year follow-up were 70% and 55% respectively. There was only one reoperation on the aortic valve.

Conclusions

Across an older patient population undergoing complex cardiac surgery, Perceval AVR facilitates acceptable short-term and medium-term outcomes in terms of both prosthetic valvular function and survival.
背景:Perceval生物假体是一种用于外科主动脉瓣置换术(AVR)的现代无缝线技术。前置瓣膜允许AVR减少交叉钳夹和体外循环次数,这与术后患者发病率和死亡率的改善有关。然而,在新西兰,报告Perceval AVR中期结果的文献很少。我们的目的是在我们的单中心调查Perceval AVR的中期结果。方法:回顾性分析2011年3月至2021年8月在我单位连续接受pereval AVR(单独或联合手术)的所有患者。结果:在10年的研究期间,145例患者(平均年龄:73.2岁,男性:71.7%,平均EuroSCORE II: 3.78%)接受了Perceval AVR。最常见的手术指征是主动脉瓣狭窄(82.5%)。手术病例量很复杂,只有27.6%的患者首次接受了孤立性AVR。交叉钳夹和体外循环的平均时间分别为74.7±40.6分钟和111.3±63.6分钟。最新随访的经胸超声心动图(术后平均2.2±1.7年)显示,96%的患者没有或只有轻微的瓣旁/瓣外渗漏。30天死亡率和脑卒中发生率分别为6.2%和2.1%。5年和9.5年随访的中期生存率分别为70%和55%。只有一次主动脉瓣再手术。结论:在接受复杂心脏手术的老年患者群体中,Perceval AVR在人工瓣膜功能和生存方面促进了可接受的短期和中期结果。

Background

Venous thromboembolism (VTE), encompassing deep vein thrombosis and pulmonary embolism (PE), is a leading cause of cardiovascular morbidity and mortality. While vitamin K antagonists (VKAs) and low molecular weight heparins (LMWHs) have long served as the standard of care, non-vitamin K antagonist oral anticoagulants, particularly factor Xa inhibitors, have emerged as promising alternatives due to their favourable pharmacokinetic profiles and ease of use. This meta-analysis aimed to evaluate the efficacy and safety of factor Xa inhibitors (apixaban, rivaroxaban, and edoxaban) compared with VKAs or LMWHs in treating acute VTE and PE, including recurrence prevention and mortality outcomes.

Method

A systematic review and meta-analysis were conducted in accordance with PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) 2020 guidelines. Seven randomised controlled trials comprising 25,510 patients were included. Outcomes assessed included VTE recurrence, PE recurrence, and all-cause mortality. Subgroup analyses examined effects in cancer and non-cancer-associated VTE, VTE in renal impairment, VTE-related mortality, bleeding-related mortality, and major bleeding in cancer, non-cancer, and solid tumours. Statistical analyses were performed using a random-effects model.

Results

Factor Xa inhibitors were associated with a statistically significant 15% reduction in VTE recurrence (hazard ratio [HR] 0.85; 95% confidence interval [CI] 0.72–0.99; p=0.04). In cancer-associated VTE, they significantly reduced recurrence risk by 24% (HR 0.76; 95% CI 0.59–0.98). In patients without cancer, a non-significant 10% reduction was observed (HR 0.90; 95% CI 0.76–1.06). Major bleeding was significantly lower in patients without cancer (HR 0.76; 95% CI 0.58–0.99), while no significant difference was noted in cancer-associated VTE or solid tumour subgroups. Factor Xa inhibitors significantly reduced bleeding-related mortality by 49% (HR 0.51; 95% CI 0.26–0.99), but showed no difference in VTE-specific or all-cause mortality.

Conclusions

Factor Xa inhibitors are effective and safe alternatives to traditional anticoagulants for most patients with acute VTE. They significantly reduce VTE recurrence, particularly in patients with cancer and bleeding-related mortality. Major bleeding was significantly less in the non-cancer subgroup. These findings support their use as first-line therapy in appropriately selected patients, with consideration of individual bleeding risk, cancer type, renal function, and treatment setting.
背景:静脉血栓栓塞(VTE),包括深静脉血栓形成和肺栓塞(PE),是心血管疾病发病率和死亡率的主要原因。虽然维生素K拮抗剂(VKAs)和低分子量肝素(LMWHs)长期以来一直是标准的护理,但非维生素K拮抗剂口服抗凝剂,特别是Xa因子抑制剂,由于其良好的药代动力学特征和易于使用,已成为有希望的替代品。本荟萃分析旨在评估Xa因子抑制剂(阿哌沙班、利伐沙班和依多沙班)与vka或lmwh治疗急性静脉血栓栓塞和肺水肿的疗效和安全性,包括复发预防和死亡率结果。方法:根据PRISMA(首选系统评价和荟萃分析报告项目)2020指南进行系统评价和荟萃分析。纳入了7项随机对照试验,包括25510名患者。评估的结果包括静脉血栓栓塞复发、肺脏复发和全因死亡率。亚组分析检查了在癌症和非癌症相关静脉血栓栓塞、肾损害中的静脉血栓栓塞、静脉血栓栓塞相关死亡率、出血相关死亡率以及癌症、非癌症和实体肿瘤中的大出血的影响。采用随机效应模型进行统计分析。结果:Xa因子抑制剂与静脉血栓栓塞复发降低15%相关(风险比[HR] 0.85; 95%可信区间[CI] 0.72-0.99; p=0.04)。在与癌症相关的静脉血栓栓塞中,他们显著降低了24%的复发风险(HR 0.76; 95% CI 0.59-0.98)。在没有癌症的患者中,观察到10%的非显著性降低(HR 0.90; 95% CI 0.76-1.06)。无癌患者大出血发生率显著降低(HR 0.76; 95% CI 0.58-0.99),而与癌症相关的静脉血栓栓塞或实体肿瘤亚组无显著差异。Xa因子抑制剂显著降低出血相关死亡率49% (HR 0.51; 95% CI 0.26-0.99),但在静脉血栓栓塞特异性或全因死亡率方面没有差异。结论:对于大多数急性静脉血栓栓塞患者,Xa因子抑制剂是传统抗凝药物的有效和安全的替代方案。它们能显著降低静脉血栓栓塞的复发,尤其是癌症患者和出血相关的死亡率。非癌症亚组大出血明显减少。这些发现支持在考虑个体出血风险、癌症类型、肾功能和治疗环境的情况下,适当选择患者将其作为一线治疗。

Background: Pulmonary embolism is associated with significant mortality and remarkably often subject to misdiagnosis, which further adversely affects prognosis. Disease severity and corresponding prognosis are strongly dependent on the risk constellation and determine the therapy. Therefore, we sought to analyse how mechanical thrombectomy influences short term clinical, laboratory, and haemodynamic findings in patients with symptomatic pulmonary artery embolism.

Method: In this study, we retrospectively analysed clinical, laboratory, and haemodynamic parameters in 32 patients with symptomatic pulmonary embolism who underwent mechanical thrombectomy using the FlowTriever device. Only patients with pulmonary embolism confirmed by computed tomography pulmonary angiography and classified as intermediate-high or high risk according to the current European Society of Cardiology guidelines were included. The main outcome measures were periprocedural changes in troponin, lactate, pulmonary artery pressures, and vital signs.

Results: Reductions of increased heart rate, pulmonary arterial pressure, and right ventricle-to-left ventricle ratio were observed immediately after the procedure and in early clinical follow-up, as well as improvement in arterial oxygen saturation and demand. Interventional thrombectomy further resulted in a reduction of increased levels of high-sensitivity troponin and lactate. In summary, the analysis of this study shows consistent respiratory and haemodynamic improvements in line with other published data on mechanical thrombectomy with this device.

Conclusions: Mechanical thrombectomy in patients with pulmonary artery embolism at intermediate-high risk was associated with an immediate and significant decrease in both specific myocardial and systemic biomarkers, for which prognostic relevance has been repeatedly demonstrated.

背景:肺栓塞与高死亡率相关,且极易误诊,进而影响预后。疾病的严重程度和相应的预后在很大程度上取决于风险组合并决定治疗。因此,我们试图分析机械取栓对症状性肺动脉栓塞患者短期临床、实验室和血流动力学表现的影响。方法:在本研究中,我们回顾性分析了32例使用FlowTriever设备进行机械取栓的症状性肺栓塞患者的临床、实验室和血流动力学参数。仅纳入经计算机断层肺血管造影证实的肺栓塞患者,并根据当前欧洲心脏病学会指南分类为中高风险或高风险。主要观察指标为术中肌钙蛋白、乳酸、肺动脉压和生命体征的变化。结果:术后和早期临床随访均可观察到心率升高、肺动脉压、右心室与左心室比值降低,动脉血氧饱和度和需氧量改善。介入血栓切除术进一步降低了高敏感性肌钙蛋白和乳酸水平。总之,本研究的分析显示呼吸和血流动力学的改善与其他已发表的使用该装置机械取栓的数据一致。结论:中高风险肺动脉栓塞患者的机械取栓与特定心肌和全身生物标志物的立即显著降低相关,其预后相关性已被反复证明。
