COVID@Heart

2020

About 10% of the COVID-19 affected patients develop critical illness with a high mortality rate. This critical illness appears to be strongly linked with cardiovascular disease, as the prevalence of cardiovascular comorbidities and risk factors (such as diabetes and obesity) are often found among hospitalized COVID-19 patients. The consortium COVID@Heart believes that mitigating this cardiovascular burden of Covid-19 should start early, while patients are (still) outside the hospital.

The Research
COVID@Heart has three core activities:

Develop a tool to identify high-risk cardiovascular patients with COVID-19 in a home environment, before the critical illness emerges. This tool will allow general practitioners to better notify high-risk patients, monitor them more closely (e.g. by using home saturation measurements), prescribe preventive cardiovascular medication earlier ('moon shot') and refer them to a hospital promptly when needed.
Create a diagnostic tool to improve early differentiation between COVID-19 and a myocardial infarction, addressing the challenge of overlapping symptoms faced by general practitioners.
Design a questionnaire supplemented by select biomarkers and blood tests to enhance the detection of cardiovascular disease in COVID-19 survivors experiencing prolonged symptoms of fatigue and shortness of breath, as these symptoms are potentially linked to accelerated subclinical cardiovascular disease.

Origin
Accurate information on how cardiovascular patients fared while still at home is lacking. This information is crucial to prevent hospital admissions. Therefore, COVID@HEART focuses on people who are not hospitalized but are at home and treated by their general practitioners. The Dutch Heart Foundation supports and funds this research into the best treatment for cardiovascular patients with a coronavirus infection.

The best way to maintain a healthy lifestyle for a long time is to teach it young. This certainly applies to those groups where unhealthy behavior is common: lower socioeconomic groups, which are increasingly multi-ethnic.
The Research
In this program we are studying the causes of unhealthy behavior in ongoing cohort studies, and together with the target group (10-14 years) we are looking for new ways to teach healthy behavior (nutrition, physical activity, sitting and sleeping behavior). We develop innovative interventions that at multiple levels (family, school, neighborhood, city) change the child's environment in such a way that healthy behavior is encouraged and unhealthy behavior is discouraged.  We implement and evaluate in Amsterdam, and disseminate results to other cities.
The origin
The Heart Foundation aims for more people to make healthy choices, so that they feel vital and run less risk of developing (again) cardiovascular diseases, which was one of the themes of the reserach agenda. With its prevention programs, ZonMw contributes to the improvement of prevention practice, to health gains and to reducing socioeconomic health disparities.
Results from research show that healthy behavior cannot be taken for granted, and is strongly influenced by people's social and physical environment and socioeconomic status. Proven effective, innovative and accessible methods to enable people to maintain a healthy lifestyle for a long time are lacking. Therefore, the Dutch Heart Foundation and ZonMw have collaborated to form the program "Gezond leven: goed voor het Hart!". LIKE is one of the projects funded from this program.

Pulmonary Hypertension (PH), particularly Pulmonary Arterial Hypertension (PAH), presents a fatal complication in chronic diseases, affecting 1 in 50,000 individuals, predominantly at a young age and more often in females. The underlying genetic link involves mutations in the bone morphogenetic protein receptor type 2 (BMPR2) gene, disrupting BMP signaling. The PHAEDRA-IMPACT consortium aims to understand PH and PAH.
The Research
The research focuses on understanding PAH through the transforming growth factor-β (TGFβ) signaling pathway, particularly influenced by mutations in the bone morphogenetic protein receptor type 2 (BMPR2) gene, prevalent in heritable and some non-hereditary PAH cases. The PHAEDRA initiative identified compounds that modulate the TGFβ/BMP balance, showing efficacy in restoring endothelial function and reversing pulmonary vascular remodeling in preclinical models, though not curing PAH, making early detection crucial.
PHAEDRA has identified biomarkers for timely diagnosis and personalized treatment. PHAEDRA-IMPACT will enhance early detection using non-invasive risk assessments, imaging, and biomarker profiling to detect pre-capillary PH. Precision medicine will guide tailored therapies based on advanced imaging and biomarker analyses, addressing disease progression variability among predisposed individuals.
Additionally, patient-derived induced pluripotent stem (iPS) cells will be used in 3D culture models of lung and heart tissues to uncover PAH mechanisms and identify therapeutic targets. This comprehensive approach aims to advance our understanding of PAH pathogenesis, accelerate drug development, and enable personalized treatment and preventive strategies for individuals at risk or affected by PH.
Origin
This consortium was funded through the Impulse Grant program by the Dutch Heart Foundation.
