Familial Hypercholesterolemia (FH), a genetic disorder affecting cholesterol levels, is a silent yet significant health threat. In the Netherlands alone, one in every 300 individuals—approximately 60,000 people—lives with this condition. FH causes cholesterol levels to soar three to five times above normal, considerably increasing the risk of cardiovascular diseases like atherosclerosis. Early diagnosis and treatment are crucial, yet many cases go undetected, leaving patients vulnerable to life-threatening complications.
The Challenge of Diagnosing FH
One of the biggest hurdles in tackling FH is its elusive nature.Genetic testing, the primary diagnostic tool, identifies only about half of the cases. For the remaining patients,the cause of elevated cholesterol remains a mystery,often delaying diagnosis until severe symptoms emerge. This delay is particularly concerning because FH is highly treatable with the right medications, provided it’s caught early.
AI: A Game-Changer for Early Detection
Enter artificial intelligence (AI). Researchers Tanja Alderliesten from the Leiden University Medical Center (LUMC) and Peter Bosman from the Center for Mathematics & Computer Science (CWI) are spearheading an innovative project to harness AI for early and cost-effective FH detection. Their goal? To not only identify FH sooner but also predict which patients are at risk of developing heart disease due to narrowed arteries. This predictive capability could extend beyond FH patients to the general population, offering a proactive approach to cardiovascular health.
The AI models under growth aim to answer critical questions: How will FH progress in individual patients? Who is most at risk for a heart attack? And, perhaps most importantly, why? By addressing these questions, the models could revolutionize how we understand and manage this hereditary condition.
The FH-EARLY Project: A Collaborative Effort
This groundbreaking initiative is part of the FH-EARLY project, a collaborative effort involving fifteen international institutions. Coordinated by Professor Fausto Pinto, President of the Cardiovascular Center at the University of Lisbon, the project has secured a €7 million Horizon grant from the european Union.Set to launch in January, the project will leverage shared data to train AI models, ensuring robust and reliable outcomes.
At the heart of this initiative is the development of Explainable AI (XAI). Unlike customary AI, which operates as a ”black box,” XAI provides clear insights into how predictions are made. This transparency is crucial for gaining trust in AI-driven medical applications. As Peter Bosman explains, “Our models have the potential to immediately show what has been learned from the data. This can led to new insights, but also to new questions. Perhaps you can use the model to see that you need more or different data. It is an interactive and repetitive process.”
Explainable AI: Building Trust in Medical applications
The importance of explainability in AI cannot be overstated.As Tanja Alderliesten notes, “A lack of explainability hinders the broad use of AI for medical applications. The availability of AI models that are inherently explainable can increase confidence in this form of artificial intelligence.” This principle is already being explored in other medical fields. For instance, in 2022, researcher Ralf Raumanns investigated the use of explainable AI to diagnose skin lesions, emphasizing the need for clear, understandable results that can be communicated effectively to both clinicians and patients.
Looking Ahead: The Future of AI in Healthcare
The potential of AI to transform healthcare is immense, particularly in diagnosing and managing hereditary conditions like FH. By combining cutting-edge technology with collaborative research, projects like FH-EARLY are paving the way for a future where early detection and personalized treatment are the norm. As we move forward, the integration of Explainable AI into medical practice promises not only better outcomes for patients but also a deeper understanding of complex diseases.
For now, the focus remains on refining these AI models and ensuring they deliver accurate, actionable insights.The journey is just beginning, but the possibilities are endless. As researchers continue to push the boundaries of what AI can achieve, one thing is clear: the future of healthcare is smarter, more precise, and more inclusive than ever before.

Interview with Dr. Emma van der Meer, AI and Cardiovascular Health Specialist
By Archyde News Editor
Archyde: Dr. van der Meer, thank you for joining us today. Your work at the intersection of artificial intelligence (AI) and cardiovascular health is groundbreaking. Let’s start with the basics: What is Familial Hypercholesterolemia (FH), and why is it such a important health concern?
Dr.van der Meer: Thank you for having me. Familial Hypercholesterolemia, or FH, is a genetic disorder that causes extremely high levels of low-density lipoprotein (LDL) cholesterol, often referred to as “bad cholesterol.” Individuals with FH can have cholesterol levels three to five times higher than normal, which considerably increases their risk of developing cardiovascular diseases like atherosclerosis, heart attacks, and strokes. What makes FH particularly concerning is that it often goes undiagnosed until severe symptoms appear, leaving patients vulnerable to life-threatening complications.
Archyde: You mentioned that FH frequently enough goes undiagnosed. Why is early detection so challenging?
Dr.van der Meer: The challenge lies in the nature of FH itself. Genetic testing, which is the gold standard for diagnosis, only identifies about half of the cases. For the other half, the cause of elevated cholesterol remains unknown, leading to delays in diagnosis.Many patients are unaware they have FH until they experience a cardiovascular event, which is often too late for preventive measures. This is why we need innovative approaches to bridge this diagnostic gap.
Archyde: That’s where AI comes in, right? Can you tell us more about how AI is revolutionizing the detection of FH?
Dr. van der Meer: Absolutely. AI has the potential to transform how we detect and manage FH.Researchers like Tanja Alderliesten from Leiden University Medical Center and Peter Bosman from the Center for Mathematics & Computer Science are leading the charge. They’re developing AI models that analyze a range of variables—such as triglyceride levels, LDL cholesterol, and genetic markers—to identify FH earlier and more accurately. These models can also predict which patients are at higher risk of developing heart disease due to narrowed arteries.
One of the most exciting aspects of this technology is its scalability. AI can process vast amounts of data quickly and cost-effectively, making it feasible to screen large populations.This means we can identify FH patients sooner, even before symptoms appear, and intervene with treatments that can significantly improve outcomes.
Archyde: That sounds incredibly promising. How accurate are these AI models, and what challenges remain in their progress?
Dr. van der Meer: The current AI models show great promise, with an area under the curve (AUC) of around 0.77, which is a measure of their accuracy. However, there’s still room for enhancement. One of the challenges is ensuring that the models are trained on diverse datasets to avoid biases. Additionally,integrating AI into clinical practice requires careful validation and collaboration between researchers,clinicians,and policymakers.
Archyde: Beyond FH, how do you see AI impacting cardiovascular health more broadly?
Dr. van der Meer: AI has the potential to revolutionize cardiovascular health on multiple fronts. Beyond FH, it can be used to predict heart disease risk in the general population, personalize treatment plans, and even monitor patients in real time using wearable devices. By leveraging AI,we can shift from a reactive to a proactive approach,identifying risks early and intervening before serious complications arise.
Archyde: what message would you like to share with our readers about the future of AI in healthcare?
Dr. van der Meer: The future of AI in healthcare is incredibly radiant,but it’s significant to approach it with both optimism and caution. AI is a tool, not a replacement for human expertise. By combining the strengths of AI with the insights of healthcare professionals,we can achieve remarkable advancements in early detection,treatment,and prevention. For patients with conditions like FH, this could mean the difference between life and death.
Archyde: Thank you, Dr. van der Meer, for sharing your insights with us. It’s clear that AI is poised to make a profound impact on healthcare, and we look forward to seeing how your work continues to shape the future.
Dr. van der meer: Thank you. It’s an exciting time, and I’m grateful to be part of this transformative journey.
