HoFH (homozygous familial hypercholesterolaemia) affects individuals from birth and significantly increases the risk of heart disease already early in life. Despite its severity and the urgency to act, HoFH remains largely underdiagnosed and misunderstood.
With heterozygous FH (the common form of FH) affecting 1 person in 250–300, and homozygous FH (the rare and severe one) affecting 1 person in 250,000–360,000, it is estimated that every day, somewhere in the world, one child is born with HoFH. In some populations, such as French Canadians, Afrikaners in South Africa, or Christian Lebanese, HoFH prevalence may be at least 10-fold higher due to founder effects. Yet, the early detection, correct diagnosis and treatment initiation are a huge challenge, with only 10% of people with FH currently diagnosed and even less optimally treated, leaving those affected at a high risk of series health consequences early in life.
That's why it's crucial for us to come together to raise awareness and support those living with this condition.
"May the 4th" resonates with "May the Force be with you," an iconic line from the global cultural phenomenon, Star Wars. This connection has made the date a playful nod to the series. Coinciding with HoFH Awareness Day, "May the 4th" underscores the importance of resilience and strength, echoing the themes of overcoming adversity found in Star Wars, and highlighting the courage needed to confront health challenges.
