Article Synopsis
  • A new machine learning algorithm was developed to predict all-cause mortality and heart failure hospitalization in patients with implantable cardioverter-defibrillators (ICDs), aiming to improve personalized risk assessments compared to traditional methods.
  • The study used a large cohort from the Veterans Health Administration, analyzing data to identify risk factors and utilizing random forest techniques for accurate predictions over 3-month and 1-year intervals.
  • Results showed strong predictive accuracy, with receiver-operating characteristic curve values indicating the model's effectiveness in distinguishing patient outcomes based on baseline demographics and ICD data.

Article Synopsis
  • The study looked at deaths in the US caused by problems with the heart's electrical system (conduction abnormalities) from 1999 to 2022.
  • About 207,861 people died from these issues, with a big spike in deaths during the COVID-19 years (2020-2021).
  • Males and non-Hispanic Black individuals had higher death rates, especially in rural areas compared to big cities, showing that more work is needed to help those groups.

Introduction: The aim of this review is to identify common mood concerns in ICD patients and suggest brief psychological screeners essential for early detection and monitoring in patient care.

Areas Covered: Reliable and valid psychological assessment tools are reviewed, including those specifically designed for ICD patient populations.

Expert Opinion: Psychological assessment, in combination with cardiologic standard of care, can help overcome many barriers associated with poor implantable cardioverter-defibrillator (ICD) management and related cardiovascular outcomes.

Background: Black patients meeting indications for implantable cardioverter-defibrillators (ICDs) have lower rates of implantation compared with White patients. There is little understanding of how mental health impacts the decision-making process among Black patients considering ICDs. Our objective was to assess the association between depressive symptoms and ICD implantation among Black patients with heart failure.

Background: Trials evaluating implantable hemodynamic monitors to manage patients with heart failure (HF) have shown reductions in HF hospitalizations but not mortality. Prior meta-analyses assessing mortality have been limited in construct because of an absence of patient-level data, short-term follow-up duration, and evaluation across the combined spectrum of ejection fractions.

Objectives: The purpose of this meta-analysis was to determine whether management with implantable hemodynamic monitors reduces mortality in patients with heart failure and reduced ejection fraction (HFrEF) and to confirm the effect of hemodynamic-monitoring guided management on HF hospitalization reduction reported in previous studies.

Background: Paroxysmal supraventricular tachycardia (PSVT) is a common episodic arrhythmia characterized by unpredictable onset and burdensome symptoms including palpitations, dizziness, chest pain, distress, and shortness of breath. Treatment of acute episodes of PSVT in the clinical setting consists of intravenous adenosine, beta-blockers, and calcium channel blockers (CCBs). Etripamil is an intranasally self-administered L-type CCB in development for acute treatment of AV-nodal dependent PSVT in a nonmedical supervised setting.

Introduction: The pivotal study of the extravascular implantable cardioverter-defibrillator (EV ICD) recently demonstrated primary efficacy and safety endpoints comparable to previous ICD systems. Patient experience with this novel device has not been reported. The current study examined the standardized patient-reported outcome (PRO) metrics of quality of life (QOL) and patient acceptance of the device.

Article Synopsis
  • A scale to measure "health security in chronic illness" (HSCI) was tested on 176 Canadian patients with cardiac devices, using remote monitoring over two timepoints.
  • The analysis identified two main factors: "support," which decreased over time, and "certainty," which remained stable.
  • Patients with implantable cardioverter defibrillators reported feeling less secure about their health over time compared to those with pacemakers.

The disparities in atrial fibrillation (AF) care are partially attributed to inadequate access to providers with specialized training in AF. Primary care providers (PCPs) are often the sole providers of AF care in under-resourced regions. As such, we sought to create a virtual education intervention for PCPs and to evaluate its impact on the use of stroke risk reduction strategies in patients with AF.

Background: In patients with symptomatic heart failure (HF) and previous heart failure hospitalization (HFH), hemodynamic-guided HF management using a wireless pulmonary artery pressure (PAP) sensor reduces HFH, but it is unclear whether these benefits extend to patients who have not been recently hospitalized but remain at risk because of elevated natriuretic peptides (NPs).

Objectives: This study assessed the efficacy and safety of hemodynamic-guided HF management in patients with elevated NPs but no recent HFH.

Methods: In the GUIDE-HF (Hemodynamic-Guided Management of Heart Failure) trial, 1,000 patients with New York Heart Association (NYHA) functional class II to IV HF and either previous HFH or elevated NP levels were randomly assigned to hemodynamic-guided HF management or usual care.

Background: Racial disparities in implantable cardioverter-defibrillator (ICD) implantation are multifactorial and are partly explained by higher refusal rates.

Objective: To assess the effectiveness of a video decision support tool for Black patients eligible for an ICD.

Design: Multicenter, randomized clinical trial conducted between September 2016 and April 2020.

Background: Shared decision-making (SDM) is an approach in which patients and clinicians act as partners in making medical decisions. Patients receive the information needed to decide and are encouraged to balance risks, benefits, and preferences. Informative materials are vital to SDM.

The term "psychologically informed health care" refers to the comprehensive integration of psychological principles into health care. Psychologically informed health care has the potential to lead to a transformation of care, resulting in truly transdisciplinary care. To facilitate its future development, we discuss key characteristics of this approach.

Background: Hemodynamically-guided management using an implanted pulmonary artery pressure sensor is indicated to reduce heart failure (HF) hospitalizations in patients with New York Heart Association (NYHA) functional class II-III with a prior HF hospitalization or those with elevated natriuretic peptides.

Objectives: The authors sought to evaluate the effect of left ventricular ejection fraction (EF) on treatment outcomes in the GUIDE-HF (Hemodynamic-GUIDEd management of Heart Failure) randomized trial.

Methods: The GUIDE-HF randomized arm included 1,000 NYHA functional class II-IV patients (with HF hospitalization within the prior 12 months or elevated natriuretic peptides adjusted for EF and body mass index) implanted with a pulmonary artery pressure sensor, randomized 1:1 to a hemodynamically-guided management group (treatment) or a control group (control).

Background Oral anticoagulation reduces stroke and disability in atrial fibrillation (AF) but is underused. We evaluated the effects of a novel patient-clinician shared decision-making (SDM) tool in reducing oral anticoagulation patient's decisional conflict as compared with usual care. Methods and Results We designed and evaluated a new digital decision aid in a multicenter, randomized, comparative effectiveness trial, ENHANCE-AF (Engaging Patients to Help Achieve Increased Patient Choice and Engagement for AF Stroke Prevention).
