Article Synopsis
- Researchers aimed to integrate a predictive algorithm using data from cardiovascular implantable electronic devices (CIEDs) to assess the risk of heart failure hospitalization (HFH) within 30 days in patients.
- They monitored 358 patients over a 90-day period, identifying that 20% were at high risk based on remote CIED transmissions, with clinicians following up and assessing symptoms.
- The findings showed that clinicians successfully contacted nearly all high-risk patients, with over two-thirds receiving medical interventions, indicating promise for enhancing heart failure management; however, further randomized trials are necessary to evaluate the effectiveness of these interventions.
Article Synopsis
- Paroxysmal atrial fibrillation (pAF) can develop into persistent atrial fibrillation (psAF), but some patients experience psAF without previous pAF, which might influence their response to direct current cardioversion (DCCV).
- This study aimed to analyze how a history of pAF impacts recurrence rates post-DCCV in patients with their first psAF episode.
- Findings showed that patients with primary psAF had longer AF survival times and less recurrence after DCCV compared to those with a history of pAF, suggesting that pAF patients may require more proactive rhythm control strategies.
Background: There is conflicting evidence on the efficacy of primary prevention implantable cardioverter-defibrillator (ICD) implantation in the elderly.
Objective: The purpose of this study was to determine the efficacy and safety of ICD implantation in patients 70 years and older.
Methods: Patients (n = 167) aged 70 years or older and eligible for ICD implantation were randomly assigned (1:1) to receive either optimal medical therapy (OMT) (n = 85) or OMT plus ICD (n = 82).
Competing risks of monomorphic vs. non-monomorphic ventricular arrhythmias in primary prevention implantable cardioverter-defibrillator recipients: Global Electrical Heterogeneity and Clinical Outcomes (GEHCO) study.

Article Synopsis
- The study aimed to compare risk factors for monomorphic ventricular tachycardia (MMVT) and polymorphic ventricular tachycardia/ventricular fibrillation (PVT/VF) in patients, indicating MMVT ablation can reduce shock frequency and enhance survival.
- A cohort of 2,668 patients was analyzed using Cox models to adjust for demographic and clinical factors, with significant associations found between MMVT risk and various electrocardiogram metrics.
- The research developed predictive models for MMVT and PVT/VF, achieving high accuracy in identifying high-risk patients, which can assist in procedural planning for better patient outcomes.
Background: Remote monitoring (RM) of pacemakers and implantable cardioverter-defibrillators (ICDs) is a Class 1, Level of Evidence A recommendation because of its multitude of clinical benefits. However, RM adherence rates are suboptimal, precluding patients from achieving these benefits. There is a need for direct-to-patient efforts to improve adherence.
