Background

For comprehensive electrocardiogram (ECG) synthesis, a recent promising approach has been based on a heart model with physical and chemical cardiac parameters. However, the problem is that such approach requires a high-cost and limited environment using supercomputers owing to the massive computation.

Objective

The purpose of this study is to develop an efficient method for synthesizing 12-lead ECG signals from cardiac parameters.

Methods

The proposed method is based on a variational autoencoder (VAE). The encoder and decoder of the VAE are conditioned by the cardiac parameters so that it can model the relationship between the ECG signals and the cardiac parameters. The training data are produced by a comprehensive, finite element method (FEM)-based heart simulator. New ECG signals can then be synthesized by inputting the cardiac parameters into the trained VAE decoder without relying on enormous computational resources. We used 2 metrics to evaluate the quality of ECG signals synthesized by the proposed model.

Results

Experimental results showed that the proposed model synthesized adequate ECG signals while preserving empirically important feature points and the overall signal shapes. We also explored the optimal model by varying the number of layers and the size of latent variables in the proposed model that balances the model complexity and the simulation accuracy.

Conclusion

The proposed method has the potential to become an alternative to computationally expensive FEM-based heart simulators. It is able to synthesize ECGs from various cardiac parameters within seconds on a personal laptop computer.

背景对于心电图(ECG)的综合合成,最近一种很有前途的方法是基于具有物理和化学心脏参数的心脏模型。本研究的目的是开发一种从心脏参数合成 12 导联心电图信号的高效方法。方法所提出的方法基于变异自动编码器(VAE)。VAE 的编码器和解码器以心脏参数为条件,从而可以模拟心电信号与心脏参数之间的关系。训练数据由基于有限元法(FEM)的综合心脏模拟器生成。然后,将心脏参数输入训练有素的 VAE 解码器,就能合成新的心电信号,而无需依赖庞大的计算资源。实验结果表明,所提出的模型能合成适当的心电信号,同时保留了经验上重要的特征点和整体信号形状。我们还通过改变拟议模型的层数和潜变量大小,探索了平衡模型复杂性和模拟准确性的最佳模型。它能在个人笔记本电脑上根据各种心脏参数在几秒钟内合成心电图。

Background

Remote monitoring (RM) of cardiac implantable electronic device (CIED) patients is now considered standard of care. However, a fundamental requirement of RM is continuous connectivity between the patient’s implanted device and the CIED manufacturer’s central server. This study examined the rate of RM disconnections in CIED recipients and the impact of short message service (SMS) to facilitate reconnections.

Methods

Using a platform that collects RM data from CIED manufacturers, we retrospectively examined the disconnection and reconnection events in 6085 patients from 20 medical centers. Each medical center reported their usual practice regarding RM disconnections, which consisted of either an automatic SMS from the platform to patients who were disconnected for 2 weeks or the standard of care (SC) of a phone call to patients.

Results

During a 1-year period, 43% of patients had at least 1 disconnection. Half of these patients experienced multiple disconnections. The use of SMS reduced the time to reconnection by 43% in comparison to SC. The median time to reconnect a disconnected patient was 11.0 [3.2, 29.0] days for SC vs 6.3 [1.3, 22.0] days for SMS (P < .0001). Furthermore, there was a high rate of reconnections within the first 48 hours of the SMS message, which was nearly double that in the SC arm.

Conclusion

This study demonstrates the feasibility of an automatic system to deliver an SMS to patients with a disconnected CIED to facilitate early reconnection to RM.

背景对心脏植入式电子设备(CIED)患者进行远程监护(RM)现已被视为护理标准。然而,RM 的一个基本要求是患者的植入设备与 CIED 制造商的中央服务器之间的持续连接。本研究调查了CIED接受者的RM断线率,以及短信服务(SMS)对促进重新连接的影响。方法利用从CIED制造商处收集RM数据的平台,我们回顾性地调查了来自20个医疗中心的6085名患者的断线和重新连接事件。每个医疗中心都报告了他们在RM断线方面的惯常做法,包括由平台自动向断线2周的患者发送短信,或按照标准护理(SC)给患者打电话。其中一半患者经历了多次断线。与 SC 相比,使用短信将重新连接的时间缩短了 43%。断线患者重新连接的中位时间为 SC 11.0 [3.2, 29.0] 天 vs SMS 6.3 [1.3, 22.0] 天(P < .0001)。此外,短信发出后 48 小时内重新连接的比例很高,几乎是 SC 组的两倍。结论这项研究证明了自动系统向断开 CIED 连接的患者发送短信以促进尽早重新连接到 RM 的可行性。

Background

Smartwatches enable continuous and noninvasive time series monitoring of cardiovascular biomarkers like heart rate (from photoplethysmograms), step counter, skin temperature, et cetera; as such, they have promise in assisting in early detection and prevention of cardiovascular disease. Although these biomarkers may not be directly useful to physicians, a machine learning (ML) model could find clinically relevant patterns. Unfortunately, ML models typically need supervised (ie, annotated) data, and labeling of large amounts of continuous data is very labor intensive. Therefore, ML methods that are data efficient, ie, needing a low number of labels, are required to detect potential clinical value in patterns found in wearable data.

Objective

The primary study objective of the ME-TIME (Machine Learning Enabled Time Series Analysis in Medicine) study is to design an ML model that can detect atrial fibrillation (AF) and heart failure (HF) from wearable data in a data-efficient manner. To achieve this, self-supervised and weakly supervised learning techniques are used.

Methods

Two hundred subjects (100 reference, 50 AF, and 50 HF) are being invited to participate in wearing a Fitbit fitness tracker for 3 months. Interested volunteers are sent a questionnaire to determine their health, in particular cardiovascular health. Volunteers without any (history of) serious illness are assigned to the reference group. Participants with AF and HF are recruited in the Haga teaching hospital in The Hague, The Netherlands.

Results

Enrollment commenced on May 1, 2022, and as of the time of this report, 62 subjects have been included in the study. Preliminary analysis of the data reveals significant inter-subject variability. Notably, we identified heart rate recovery curves and time-delayed correlations between heart rate and step count as potential strong indicators for heart disease.

Conclusion

Using self-supervised and multiple-instance learning techniques, we hypothesize that patterns specific to AF and HF can be found in continuous data obtained from smartwatches.

背景智能手表能够对心率(来自光速图)、步数计数器、皮肤温度等心血管生物标记进行连续、无创的时间序列监测;因此,它们有望协助早期检测和预防心血管疾病。虽然这些生物标志物对医生可能没有直接用处,但机器学习(ML)模型可以找到与临床相关的模式。遗憾的是,ML 模型通常需要有监督(即注释)的数据,而对大量连续数据进行标注非常耗费人力。因此,需要数据效率高的 ML 方法(即只需少量标签)来检测可穿戴数据中发现的模式是否具有潜在的临床价值。目标ME-TIME(Machine Learning Enabled Time Series Analysis in Medicine)研究的主要研究目标是设计一种 ML 模型,以数据效率高的方式从可穿戴数据中检测心房颤动(AF)和心力衰竭(HF)。为此,研究人员采用了自监督和弱监督学习技术。方法研究人员邀请 200 名受试者(100 名参照者、50 名房颤受试者和 50 名心衰受试者)佩戴 Fitbit 健身追踪器 3 个月。有兴趣的志愿者会收到一份调查问卷,以确定其健康状况,尤其是心血管健康状况。没有任何严重疾病(病史)的志愿者被分配到参照组。患有房颤和高血压的受试者在荷兰海牙的哈加教学医院招募。结果2022年5月1日开始招募,截至本报告发布时,已有62名受试者被纳入研究。对数据的初步分析表明,受试者之间的差异很大。值得注意的是,我们发现心率恢复曲线和心率与步数之间的延时相关性是心脏病的潜在有力指标。结论利用自监督和多实例学习技术,我们假设可以从智能手表获得的连续数据中发现房颤和高血压的特定模式。

Background

Heart failure (HF) is a progressive condition with high global incidence. HF has two main subtypes: HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF). There is an inherent need for simple yet effective electrocardiogram (ECG)-based artificial intelligence (AI; ECG-AI) models that can predict HF risk early to allow for risk modification.

Objective

The main objectives were to validate HF risk prediction models using Multi-Ethnic Study of Atherosclerosis (MESA) data and assess performance on HFpEF and HFrEF classification.

Methods

There were six models in comparision derived using ARIC data. 1) The ECG-AI model predicting HF risk was developed using raw 12-lead ECGs with a convolutional neural network. The clinical models from 2) ARIC (ARIC-HF) and 3) Framingham Heart Study (FHS-HF) used 9 and 8 variables, respectively. 4) Cox proportional hazards (CPH) model developed using the clinical risk factors in ARIC-HF or FHS-HF. 5) CPH model using the outcome of ECG-AI and the clinical risk factors used in CPH model (ECG-AI-Cox) and 6) A Light Gradient Boosting Machine model using 288 ECG Characteristics (ECG-Chars). All the models were validated on MESA. The performances of these models were evaluated using the area under the receiver operating characteristic curve (AUC) and compared using the DeLong test.

Results

ECG-AI, ECG-Chars, and ECG-AI-Cox resulted in validation AUCs of 0.77, 0.73, and 0.84, respectively. ARIC-HF and FHS-HF yielded AUCs of 0.76 and 0.74, respectively, and CPH resulted in AUC = 0.78. ECG-AI-Cox outperformed all other models. ECG-AI-Cox provided an AUC of 0.85 for HFrEF and 0.83 for HFpEF.

Conclusion

ECG-AI using ECGs provides better-validated predictions when compared to HF risk calculators, and the ECG feature model and also works well with HFpEF and HFrEF classification.

背景心力衰竭(HF)是一种进展性疾病,全球发病率很高。心力衰竭主要有两种亚型:射血分数保留型心力衰竭(HFpEF)和射血分数降低型心力衰竭(HFrEF)。目标主要目的是利用多种族动脉粥样硬化研究(MESA)数据验证心房颤动风险预测模型,并评估 HFpEF 和 HFrEF 分类的性能。1)预测 HF 风险的 ECG-AI 模型是利用原始 12 导联 ECG 和卷积神经网络开发的。2)ARIC(ARIC-HF)和 3)弗雷明汉心脏研究(FHS-HF)的临床模型分别使用了 9 个和 8 个变量。4) 利用 ARIC-HF 或 FHS-HF 的临床风险因素建立的 Cox 比例危险(CPH)模型。5)使用 ECG-AI 结果和 CPH 模型中使用的临床风险因素的 CPH 模型(ECG-AI-Cox);6)使用 288 个心电图特征的轻梯度提升机模型(ECG-Chars)。所有模型都在 MESA 上进行了验证。结果ECG-AI、ECG-Chars 和 ECG-AI-Cox 的验证 AUC 分别为 0.77、0.73 和 0.84。ARIC-HF 和 FHS-HF 的 AUC 分别为 0.76 和 0.74,CPH 的 AUC = 0.78。ECG-AI-Cox 的表现优于所有其他模型。ECG-AI-Cox为HFrEF提供的AUC为0.85,为HFpEF提供的AUC为0.83。结论与HF风险计算器和心电图特征模型相比,使用心电图的ECG-AI能提供更好的验证预测结果,而且在HFpEF和HFrEF分类中效果也很好。

Development of text messages for primary prevention of cardiovascular disease in persons with HIV 开发用于艾滋病病毒感染者心血管疾病初级预防的短信

Objective

Persons with HIV (PWH) have increased risk for atherosclerotic cardiovascular disease (CVD). Despite this increased risk, perceived cardiovascular risk among PWH is low, and interventions that are known to be beneficial in the general population, such as statins, have low uptake in this population. We sought to develop a bank of text messages about (1) the association between HIV and CVD and (2) advice on reducing cardiovascular risk.

Methods

We developed an initial bank of 162 messages. We solicited feedback from 29 PWH recruited from outpatient clinics providing HIV care at a large urban tertiary medical center and a public hospital in San Francisco, California. Participants reviewed 7–10 messages each and rated message usefulness, readability, and potential impact on behavior on a scale from 1 (least) to 5 (most). We also collected open-ended feedback on the messages and data on preferences about message timing.

Results

The average score for the messages was 4.4/5 for usefulness, 4.4/5 for readability, and 4.0/5 for potential impact on behavior. The text messages were iteratively revised based on participant feedback, and lowest-rated messages were removed from the message bank. The final message bank included 116 messages on diet (30.2%), physical activity (24.8%), tobacco (11.2%), the association between HIV and cardiovascular disease (9.5%), general heart health (6.9%), cholesterol (5.2%), blood pressure (4.3%), blood sugar (2.6%), sleep (2.6%), and weight (2.6%).

Conclusion

We describe an approach for developing educational text messages on primary prevention of cardiovascular disease among PWH.

目标艾滋病病毒感染者(PWH)罹患动脉粥样硬化性心血管疾病(CVD)的风险增加。尽管风险增加了,但感染艾滋病病毒的人群对心血管风险的认知程度却很低,而且已知对普通人群有益的干预措施(如他汀类药物)在这一人群中的接受率也很低。我们试图开发一个短信库,内容包括:(1) HIV 与心血管疾病之间的关系;(2) 降低心血管疾病风险的建议。我们从加利福尼亚州旧金山市一家大型城市三级医疗中心和一家公立医院提供艾滋病护理的门诊诊所招募了 29 名艾滋病感染者,并向他们征求了反馈意见。参与者每人查看了 7-10 条信息,并对信息的实用性、可读性和对行为的潜在影响进行了评分,评分标准从 1 分(最低)到 5 分(最高)不等。我们还收集了关于信息的开放式反馈以及关于信息发布时间偏好的数据。结果信息的有用性平均得分为 4.4/5,可读性平均得分为 4.4/5,对行为的潜在影响平均得分为 4.0/5。根据参与者的反馈,对短信进行了反复修改,并将评分最低的短信从信息库中删除。最终的信息库包括 116 条信息,内容涉及饮食(30.2%)、体育锻炼(24.8%)、烟草(11.2%)、艾滋病与心血管疾病的关系(9.5%)、一般心脏健康(6.9%)、胆固醇(5.2%)、血压(4.3%)、血糖(2.6%)、睡眠(2.6%)和体重(2.6%)。
