- Brief Summary
The aim of this pilot study is to explore the feasibility, safety and potential benefit of haemodynamically-guided heart failure (HF) treatment using the Seerlinq telemedical monitoring and to compare the outcomes vs. standard of care.
Study hypothesis:
Haemodynamically-guided HF treatment using the Seerlinq telemedical monitoring will improve patient's perception of their health status and quality of life and will be more efficient compared to the standard of care.
Study objectives:
The primary objective is to compare the ability of haemodynamically-guided HF treatment using the Seerlinq telemedical monitoring system vs. standard of care to improve patients' perception of their health status measured by a standardized questionnaire in patients with HF.
The secondary objectives:
1. To compare the efficacy of haemodynamically-guided HF treatment using the Seerlinq telemedical monitoring system vs. standard of care in the treatment of patients with HF measured by plasmatic levels of N-terminal pro-brain natriuretic peptide (NT-proBNP), number of hospitalizations for heart failure and cardiovascular mortality
2. To compare the ability of haemodynamically-guided HF treatment using the Seerlinq telemedical monitoring system vs. standard of care to improve quality of life (QoL) measured by standardized questionnaire in patients with HF Tertiary objective includes comparison of the cost-effectivity of haemodynamically-guided HF treatment using the Seerlinq telemedical monitoring system vs. standard of care in the treatment of patients with HF.
- Detailed Description
Background:
Heart failure affects more than 6.2 million people in the United States and has a 5-year mortality rate of approximately 42%. Due to population growth, aging, and the increasing prevalence of comorbidities, the absolute number of hospital admissions for HF is expected to increase considerably in the future. Signs and symptoms of congestion are the predominant cause of these hospital admissions. Importantly, elevated filling pressures precede HF hospitalizations by weeks. Therefore, early recognition of increased filling pressures and appropriate intervention may prevent further deterioration and hospitalizations. Current strategies for the early detection of HF exacerbation mainly involve the use of invasive intracardiac pressure measurements and the incorporation of preclinical markers of worsening HF related to autonomic adaptation, patient activity, and intrathoracic impedance into cardiac implantable electronic devices. However, these approaches are invasive and have not consistently demonstrated efficacy.
Therefore, a non-invasive and readily available diagnostic tool capable of identifying an increase in cardiac filling pressures could be precious in clinical practice. Photoplethysmography (PPG) measurement and analysis is an emerging technology that holds the potential to offer a cost-effective and scalable alternative for achieving this goal.
Rationale:
Technological progress allows the development of systems and devices that can monitor changes in a patient's health status from the comfort of their home. The measured data is then transmitted to medical centers, where it is immediately accessible to physicians. Telemedical monitoring (remote monitoring) offers several benefits, including continuous medical supervision. Typical symptoms of HF, such as edema or shortness of breath, may develop relatively suddenly. However, the deterioration of a patient's health is preceded by complex pathophysiological processes, such as an increase in heart pressure or hemodynamic changes, and redistribution of blood volume in the bloodstream.
For this purpose, Seerlinq HeartCore monitoring system was developed. The Seerlinq monitoring system is capable of identifying these changes in advance, allowing physicians to react promptly and manage the patient's treatment to prevent negative outcomes of HF.

- Primary Outcome Measures
Name Time Method Change in patient's perception of their health status in 6 months Measured by the Kansas City Cardiomyopathy (KCCQ-12) Questionnaire. Minimum Value: 0 Maximum Value: 100 Interpretation: Higher scores indicate better health status and quality of life for heart failure patients. Lower scores indicate worse health status, implying more severe symptoms and greater limitations due to heart failure.
- Secondary Outcome Measures
Name Time Method Number of contacts between sites and study patients up to 1 year Number of contacts between sites and study patients during participant study duration
Days alive outside hospital up to 1 year Days alive outside hospital during participant study duration
Cardiovascular mortality up to 1 year Cardiovascular mortality during participant study duration
Change in NT-proBNP plasmatic level in 6 months at Follow-up 1 and 2 a blood sample will be taken
Change in quality of life in 1 year Measured by EuroQol 5-Dimensions 5-Levels (EQ-5D-5L) Questionnaire.
Interpretation:
Higher scores (closer to 1) indicate better health-related quality of life, suggesting fewer problems in the five health dimensions.
Lower scores (closer to 0 or below) indicate worse health-related quality of life, suggesting more severe problems in the health dimensions.Change in patient's perception of their health status in 1 year Measured by the Kansas City Cardiomyopathy (KCCQ-12) Questionnaire. Minimum Value: 0 Maximum Value: 100 Interpretation: Higher scores indicate better health status and quality of life for heart failure patients.
