Heart failure (HF) is a global pandemic with a growing prevalence and is a growing burden on the healthcare system. Machine learning (ML) has the potential to revolutionize medicine and can be applied in many different forms to aid in the prevention of symptomatic HF (stage C). HF prevention currently has several challenges, specifically in the detection of pre-HF (stage B). HF events are missed in contemporary models, limited therapeutic options are proven to prevent HF, and the prevention of HF with preserved ejection is particularly lacking. ML has the potential to overcome these challenges through existing and future models. ML has limitations, but the many benefits of ML outweigh these limitations and risks in most scenarios. ML can be applied in HF prevention through various strategies such as refinement of incident HF risk prediction models, capturing diagnostic signs from available tests such as electrocardiograms, chest x-rays, or echocardiograms to identify structural/functional cardiac abnormalities suggestive of pre-HF (stage B HF), and interpretation of biomarkers and epigenetic data. Altogether, ML is able to expand the screening of individuals at risk for HF (stage A HF), identify populations with pre-HF (stage B HF), predict the risk of incident stage C HF events, and offer the ability to intervene early to prevent progression to or decline in stage C HF. In this narrative review, we discuss the methods by which ML is utilized in HF prevention, the benefits and pitfalls of ML in HF risk prediction, and the future directions.
心力衰竭(HF)是一种全球流行病,发病率越来越高,对医疗保健系统造成的负担也越来越重。机器学习(ML)具有彻底改变医学的潜力,可以以多种不同的形式应用于无症状心力衰竭(C 阶段)的预防。高血压预防目前面临着一些挑战,特别是在检测高血压前期(B 阶段)方面。在现代模型中,心房颤动事件被遗漏,经证实可预防心房颤动的治疗方案有限,尤其缺乏对射血功能保留的心房颤动的预防。通过现有和未来的模型,ML 有可能克服这些挑战。ML 有其局限性,但在大多数情况下,ML 的诸多益处超过了这些局限性和风险。ML 可通过各种策略应用于高血压预防,如完善高血压发病风险预测模型,从心电图、胸部 X 光片或超声心动图等现有检查中捕捉诊断征象,以确定提示高血压前期(B 期高血压)的心脏结构/功能异常,以及解读生物标志物和表观遗传学数据。总之,ML 能够扩大对高危人群(A 期高血压)的筛查范围,识别高血压前期(B 期高血压)人群,预测 C 期高血压事件的发生风险,并提供早期干预的能力,以防止进展为 C 期高血压或病情恶化。在这篇叙述性综述中,我们将讨论在高频预防中使用 ML 的方法、ML 在高频风险预测中的益处和缺陷以及未来的发展方向。

Heart failure with preserved ejection fraction (HFpEF) represents an entity with complex pathophysiologic pathways, among which coronary microvascular dysfunction (CMD) is believed to be an important orchestrator. Research in the field of CMD has highlighted impaired vasoreactivity, capillary rarefaction, and inflammation as potential mediators of its development. CMD can be diagnosed via several noninvasive methods including transthoracic echocardiography, cardiac magnetic resonance, and positron emission tomography. Moreover, invasive methods such as coronary flow reserve and index of microcirculatory resistance are commonly employed in the assessment of CMD. As far as the association between CMD and HFpEF is concerned, numerous studies have highlighted the coexistence of CMD in the majority of HFpEF patients. Additionally, patients affected by both conditions may be facing an adverse prognosis. Finally, there is limited evidence suggesting a beneficial effect of renin-angiotensin-aldosterone system blockers, ranolazine, and sodium-glucose cotransporter-2 inhibitors in CMD, with further evidence being awaited regarding the impact of other pharmacotherapies such as anti-inflammatory agents.

This focused review will highlight the results of HELIOS-B, the first randomized outcomes trial evaluating a gene silencing treatment for transthyretin cardiac amyloidosis (ATTR-CM). In HELIOS-B, vutrisiran was tested against placebo and demonstrated a 28% reduction in the composite of all-cause mortality and recurrent cardiovascular events. Additionally, there were clinically significant benefits on the 6-min walk test, Kansas City Cardiomyopathy Questionnaire, and NYHA class. Discontinuation rates and adverse events were similar between treatment and control arms, suggesting that vutrisiran is well tolerated. In this review, these promising results are explored and compared with other treatment trials in ATTR-CM.

Hypertrophic cardiomyopathy (HCM) is the most common genetic heart disease worldwide and may present with or without dynamic left ventricular outflow tract obstruction (LVOTO). Significant advances have been made in the management of obstructive HCM. On the other hand, despite their significant symptomatic burden, patients with non-obstructive HCM (nHCM) (i.e., without LVOTO) still do not have evidence-based therapeutical options. The recent IMPROVE-HCM study, a phase 2 randomized, double-blinded trial, aims to place a first step in filling this gap in knowledge. The study assessed the safety (primary endpoint) and efficacy (secondary endpoint) of ninerafaxstat, a novel cardiac mitotrope drug that increases adenosine triphosphate production. We highlighted the main findings of the trial, contextualizing these results within the larger landscape of completed and ongoing trials in nHCM.

With over 1 million primary heart failure (HF) hospitalizations annually, nearly 80% of patients who present to the emergency department with decompensated HF (DHF) are hospitalized. Short stay units (SSU) present an alternative to hospitalization, yet the effectiveness of the SSU strategy of care is not well known. This study is to determine the effectiveness of a SSU strategy compared with hospitalization in lower-risk patients with DHF. Our primary outcome was a composite of 30-day mortality and re-hospitalization. Key secondary outcomes included 90-day mortality and re-hospitalization, costs, and 30-day days-alive-and-out-of-hospital (DAOOH). This is a systematic review and meta-analysis, following PRISMA guidelines. MEDLINE, EMBASE, CENTRAL, CINAHL, SCOPUS, and Web of Science were searched from inception through February 2024. Either randomized trials or comparative observational studies were included if they compared outcomes between low-risk ED DHF patients admitted to an SSU (defined as an observation unit with expected stay ≤ 48 h) vs. admitted to the hospital. Two authors independently screened all titles and abstracts and then identified full texts for inclusion. Data extraction and risk of bias assessments were performed by two authors in parallel. The primary outcome was a composite of death or readmission within 30 days, reported as relative risk (RR), where a RR < 1 favored the SSU strategy. Secondary outcomes included 90-day mortality and re-hospitalization, costs, and 1-month days-alive-and-out-of-hospital (DAOOH). Of the 467 articles identified by our search strategy, only 3 full text articles were included. In meta-analysis for the primary outcome of 30-day death or readmission, the RR was 0.95 (95% CI = 0.56 to 1.63; I2 = 0%) for patients randomized to SSU vs hospitalization (2 studies, 241 patients). There were only 2 total deaths at 30 days in the 2 studies (total N = 258) which reported 30-day mortality, both in hospitalized patients. Only one study reported 90-day outcomes, showing no significant differences. Costs were lower in the SSU arm from one study, and 30-day DAOOH also favored SSU based on a single randomized trial. Based on very limited evidence, SSU provides similar efficacy for 30-day and 90-day mortality and readmission compared to hospitalization. An SSU strategy appears safe and may be cost effective.

Echocardiography represents an essential tool for imagers and clinical cardiologists in the management of patients with heart failure. Advanced heart failure (AdHF) is a more severe and, typically, later stage of HF that exposes patients to a high risk of adverse outcomes, with a 1-year mortality rate of around 50%. Currently, several therapies are available to improve the outcomes of these patients, reduce their mortality rate, and, possibly, delay the need for advanced therapies such as heart transplant and long-term mechanical circulatory support. When accurately performed and interpreted, echocardiography provides crucial information to properly tailor medical and device therapy of patients with AdHF and to identify those at even higher risk. In this review, we present the state of the art of echocardiography applications in the clinical management of patients with AdHF. We will discuss the role of echocardiography chronologically, beginning with the prediction of AdHF, proceeding through diagnosis, and detailing how echocardiography informs clinical decision-making, before concluding with indications for advanced therapies.
Graphical Abstract
The role of echocardiography in the management of patients with advanced heart failure. Echocardiography is a useful method for predicting the occurrence of AdHF during follow-up of patients with HF (top line). The diagnosis of AdHF requires an echocardiographic criterion for AdHF (middle line). In patients with AdHF, echocardiography is useful to identify patients who will benefit most from medical therapy adjustment, device therapy, and LVAD implantation.
