MyDigiTwin

2020

Cardiovascular disease (CVD) is the leading global cause of mortality and morbidity, with ischemic heart disease (IHD) representing approximately half of all CVD-related deaths. Precise, personalized risk assessment and treatment recommendations are crucial for addressing the diverse population at risk of CVD. Current standard approaches rely on algorithms that incorporate a limited set of traditional risk factors to estimate CVD and IHD risk. However, significant cardiovascular events often occur in individuals categorized as low risk, underscoring the need for ongoing research to enhance preventive strategies.

The Focus
The MyDigiTwin initiative aims to provide individuals with personalized insights into their cardiac health, enabling proactive monitoring and management of cardiovascular conditions. This integrated digital health platform empowers individuals to take control of their cardiac health by offering accessible, data-driven insights and tools.

The Research
MyDigiTwin is a pioneering research initiative focused on revolutionizing cardiac health management by integrating advanced AI technologies with extensive patient data. The development of MyDigiTwin involves harnessing large-scale longitudinal datasets from over 500,000 patients, combined with sophisticated AI algorithms. This approach enables the platform to analyze diverse health parameters and generate tailored recommendations for users based on their unique health profiles. By leveraging AI and comprehensive patient data, MyDigiTwin represents an innovative approach to preventive and personalized healthcare, facilitating early detection and intervention for cardiovascular conditions.

Origin
This project was funded within the Big Data & Health Program. The focus of this public-private research program is the use of big data for the early detection and prevention of cardiovascular diseases. The program has been developed by NWO, ZonMw, the Dutch Heart Foundation, the Top Sectors Life Sciences & Health (LSH), ICT and Creative Industry, the Ministry of Health, Welfare and Sport, and the Netherlands eScience Center. Within this research program, the ambitions of the Dutch Heart Foundation, the Ministry of Health, Welfare and Sport, and the Netherlands eScience Center were aligned with the ambitions of Commit2Data for the Top Sectors ICT, LSH, and Creative Industry, as described in the 2018-2019 Kennis- en Innovatiecontracts between NWO and the Top Sectors.

CUSTOM-AF

2020
Individuals with atrial fibrillation are at increased risk of an ischemic stroke. Active detection of atrial fibrillation (AF) and optimal referral and treatment of patients could prevent an estimated 1500 ischemic strokes annually. Effective collaboration between primary and secondary care professionals is essential for achieving this goal of stroke prevention attributed to AF. This is the primary objective of the implementation consortium known as CUSTOM-AF. The origin  The CUSTOM-AF was founded in June 2020 and restarted in 2022. CUSTOM-AF implementation consortium aims to share successful practice examples with regional networks and develop guidelines for organizing active detection and integrated care within a network. Additionally, consortium partners seek innovative methods for general practitioners to detect and manage AF without necessitating hospital referrals. With this consortium, the Dutch Heart Foundation, NVVC Connect, Harteraad, and the Dutch CardioVascular Alliance, all work together towards optimal care for patients with AF. The Dutch College of General Practitioners (NHG) serves as a key advisor to the consortium. Earlier detection and better treatment of atrial fibrillation, the most common cardiac arrhythmia in adults, is an important part of the cardiovascular disease research agenda that the Dutch Heart Foundatoin set in 2014, which funds the CUSTOM-AF consortium. The Research The scope of the consortium has been expanded to include two disorders: heart failure and AF. The consortium has undertaken significant initiatives over the past two years (2020-2022) to advance its objectives: Guideline Development: The consortium developed the "Screening and Treatment Optimization for AF" guideline, designed to facilitate early detection of AF within regional healthcare systems. Cost-Effectiveness Analysis: A comprehensive analysis conducted to assess various screening scenarios for AF, evaluating the economic feasibility of different approaches. Thematic Collaboration: In early 2022, a thematic collaboration titled "Juiste Hartzorg op de Juiste Plek" was established in partnership with the Heart Foundation and ZonMw. This collaboration secured funding for 22 regions to support transmural collaboration on AF and HF, with a focus on early detection and treatment optimization. Moving forward from September 2022, NVVC Connect will intensify support for the regions by emphasizing continuous improvement through the PDCA cycle, facilitating knowledge sharing, and implementing innovative approaches. These efforts are aimed at strengthening collaboration and improving outcomes in AF and HF care across the participating regions.

Praetorian-covid

2020
The SARS-CoV-2 pandemic has a high burden of morbidity and mortality due to development of the acute respiratory distress syndrome (ARDS). The reninangiotensin-system (RAS) plays an important role in the development of ARDS, with ACE2 (angiotensin-converting enzyme 2) being a key enzyme within this. The virus's spike protein binds to ACE2, facillitating cellular internalization. Downregulation of ACE2 results in the excessive accumulation of angiotensin II, which in turn increases pulmonary vascular permeability through stimulation of the angiotensin II type 1a receptor (AT1R), thereby exacerbating lung pathology associated with decreased ACE2 activity. Currently available AT1R blockers (ARBs) such as valsartan, have shown potential to block this pathological process mediated by angiotensin II. The Focus The primary aim of the PRAETORIAN-COVID trial is to investigate the effect of the ARB valsartan compared to placebo on the composite end point of admission to an intensive care unit, mechanical ventilation, or death of COVID-19 patients. The Research Participants receiving active treatment are administered valsartan at a dosage titrated to blood pressure, with a maximum of 160 mg twice daily. Participants receiving placebo are provided with a matching placebo. The treatment duration was 14 days or until reaching the primary endpoint, or until hospital discharge, if applicable within 14 days.Two complementary mechanisms underpin the potential efficacy of angiotensin II type 1 receptor blockers (ARBs) in preventing acute respiratory distress syndrome (ARDS) and reducing morbidity and mortality: ARBs block excessive angiotensin-mediated activation of the AT1R. ARBs upregulate ACE2 expression, leading to reduced angiotensin II levels and increased production of the protective vasodilator angiotensin 1–7. Given these mechanisms, ARBs show promise in preventing ARDS development, potentially reducing the need for intensive care unit (ICU) admission and mechanical ventilation, and ultimately lowering mortality rates associated with SARS-CoV-2 infection.
