About

This is a single-center, randomized, open-label, no-profit interventional trial designed to evaluate the effectiveness of a telemedicine-based follow-up strategy compared with standard ambulatory care in patients with newly diagnosed heart failure with reduced ejection fraction (HFrEF). The study aims to determine whether telemedicine-guided management improves the optimization of guideline-directed medical therapy (GDMT), measured as change in GDMT score at 6 months. Patients will be randomized to either a telemedicine group, involving remote multiparametric monitoring and structured teleconsultations, or a standard-of-care group based on conventional in-person follow-up. Secondary objectives include the assessment of safety, treatment adherence, quality of life, and heart failure-related urgent visits, emergency department access, and hospitalizations. This study will provide evidence on the role of telemedicine in facilitating early and effective optimization of heart failure therapy and improving clinical management in a real-world setting.

Full description

Heart failure with reduced ejection fraction (HFrEF) remains a major cause of morbidity, mortality, and healthcare utilization worldwide. Despite strong guideline recommendations supporting the early and comprehensive initiation of guideline-directed medical therapy (GDMT), real-world implementation remains suboptimal. Many patients are discharged on incomplete therapy and experience significant delays in treatment optimization, particularly during the early post-discharge phase, which is known to be a high-risk period for clinical instability. Recent evidence has highlighted the importance of rapid and structured GDMT optimization, with early intensification strategies associated with improved clinical outcomes. However, traditional care pathways, largely based on in-person follow-up visits, are often limited by logistical constraints, reduced access, and delayed clinical reassessment. In this context, telemedicine has emerged as a promising tool to facilitate early follow-up, enhance monitoring, and support timely treatment adjustments.

The TELEHEART study is a prospective, randomized, controlled trial designed to evaluate whether a telemedicine-guided strategy can improve GDMT optimization compared with standard care in patients with newly diagnosed HFrEF following hospitalization for acute heart failure or recent clinical instability. Participants will be randomized to either a telemedicine-based follow-up strategy or standard in-person care. In the intervention arm, patients will undergo an early structured telemedicine consultation shortly after discharge, supported by remote monitoring of clinical parameters, including blood pressure, heart rate, oxygen saturation, body weight, and single-lead electrocardiogram recordings. This approach is intended to enable early reassessment and facilitate timely up-titration of GDMT in accordance with current guidelines. In the control arm, patients will receive standard follow-up according to local clinical practice. The primary objective of the study is to assess the effectiveness of the telemedicine-based strategy in improving GDMT optimization, measured through a predefined GDMT score reflecting both the initiation and up-titration of the four foundational drug classes for HFrEF, according to a structured and standardized scoring system (detailed in the Outcome Measures section).

A key secondary objective is to evaluate the safety of replacing the first post-discharge in-person clinical evaluation with a structured telemedicine consultation. Safety will be assessed using a predefined composite endpoint including worsening renal function (defined as a ≥30% reduction in eGFR or eGFR <30 mL/min/1.73m²), significant hyperkalemia (serum potassium >5.5 mEq/L), and symptomatic hypotension (systolic blood pressure <90 mmHg associated with symptoms). Additional secondary objectives include the assessment of clinical outcomes, such as hospital readmissions and emergency department visits, as well as patient-reported outcomes. Treatment adherence, quality of life, and patient satisfaction with the telemedicine approach will be evaluated using validated questionnaires, including the Morisky Medication Adherence Scale (MMAS-8), the Kansas City Cardiomyopathy Questionnaire (KCCQ), and the Telehealth Usability Questionnaire (TUQ). By integrating structured telemedicine into early post-discharge management, this study aims to determine whether a more proactive, remotely supported care model can safely enhance treatment optimization and improve patient-centered outcomes in HFrEF.

Inclusion and exclusion criteria

Inclusion criteria: Participants must meet all of the following criteria:

1. Provision of written informed consent.
2. Age ≥18 years.
3. Recent diagnosis of HFrEF, defined according to ESC criteria, established in either an inpatient or outpatient setting.
4. No prior initiation of GDMT for HF at the time of enrollment, or treatment limited to a single agent with potential disease-modifying effects prescribed for a different clinical indication.
5. Availability of adequate digital literacy, either by the patient or a caregiver, defined as the ability to use electronic devices for remote communication (phone/video calls), transmission of vital parameters (body weight, blood pressure, heart rate), and interaction with digital health tools. In cases of insufficient patient digital skills, the presence of a caregiver with adequate digital competence is acceptable.
6. Any etiology of HF is eligible, including ischemic, valvular, primary or infiltrative cardiomyopathies, iatrogenic or toxic causes, and tachycardia-induced cardiomyopathy.

Exclusion Criteria:

• Ongoing treatment with two or more guideline-directed heart failure medications at the time of HFrEF diagnosis
• Presence of severe comorbidities or clinical instability requiring prolonged or continuous hospital management
• Estimated life expectancy <12 months
• Pregnancy or breastfeeding
