In a remarkable turn of events, an Essex woman who lived unknowingly with a serious heart defect for over 50 years is now gearing up for a monumental 54-mile charity cycle from London to Brighton. This life-changing revelation came after Diana Warren, 55, collapsed during a leisurely bike ride with her wife, leading to a diagnosis that has not only transformed her understanding of her health but also inspired her to give back to the community.
A Shocking Collapse
The incident unfolded in June 2022 when Diana and her wife Lisa were halfway through a 14-mile journey to Mersey Island. After stopping at a café, Diana chose a coffee and a cream tea, believing the carbs would fuel their ride. However, as she prepared to indulge, she suddenly collapsed face-first into her treat. “I don’t remember much after that,” she remarked with a chuckle, recalling the bewildering moment.
When she regained consciousness, paramedics were attending to her, and although the episode was initially dismissed as a fainting spell, a nagging concern lingered, prompting Diana to seek medical advice. Despite brushing it off as a potential menopause side effect, her wife insisted on a doctor’s visit.
Heart of the Matter
At her initial consultation, the GP suspected a heart-related issue and referred Diana to the cardiology department at Colchester Hospital. “It was a bit of a shock,” Diana reflected, “because I’d always considered myself active.” She’d spent years cycling and walking, living a life that seemed far removed from serious health concerns.
Following a series of tests, including an electrocardiogram, she received the stunning news: she had an Atrial Septal Defect (ASD), a hole in her heart that had likely been present since birth. “They said it’s been there your whole life, and it’s surprising it’s not been detected before,” she said. The defect was comparable to the size of a two pence piece, a significant opening that could lead to severe complications if untreated.
A Journey to Recovery
Diana’s diagnosis set her on a path to treatment. Initially referred for keyhole surgery to repair the defect, the attempts were unsuccessful, leading to the necessity for open-heart surgery in April 2024. “I have to say, St Bart’s were absolutely amazing the whole way through,” she praised the staff for their care and support during her hospital stay.
In addition to repairing the hole, a pacemaker was fitted to help regulate her heartbeat. Now, with regular check-ups, Diana is embracing life with renewed vigour and determination.
Cycling for a Cause
With the surgery behind her, Diana is taking on the challenge of a 54-mile bike ride on June 21, 2026, to support the British Heart Foundation. Accompanied by her brother Gary and his wife Teresa, Diana is committed to raising funds for the organisation that offers vital resources for those grappling with heart conditions.
Since January, she has been training diligently, increasing her mileage and following strength exercises recommended by the Foundation. “My squats are coming up really good!” she enthusiastically reported, embodying a spirit of resilience and determination.
Diana believes it’s crucial to give back, especially as someone who has experienced the challenges of living with a heart condition. “To help others who may find themselves in a similar situation is really important,” she emphasised, highlighting the importance of community support.
Why it Matters
Diana Warren’s story is not just about personal triumph over adversity; it underscores the significance of awareness and early diagnosis in heart health. Her experience serves as a reminder of the often-hidden health issues that can affect even the most active individuals. By sharing her journey and participating in the London to Brighton bike ride, Diana is not only advocating for heart health but also inspiring others to engage with their well-being. Her commitment to fundraising for the British Heart Foundation reflects a powerful message: together, we can support vital research and help those navigating the complexities of heart conditions.
