Sudden Cardiac Death in Young People

Debate between Chris Vince and Fleur Anderson

Monday 15th December 2025 Commons Chamber

[Chris Vince (Harlow) (Lab/Co-op)]

I thank the Speaker’s Office for finding time for this important Adjournment debate, and my hon. Friend the Minister for being in her place to hear it. I look forward to her response. I know that many Members feel passionate about this issue and look forward to taking as many interventions as I can.

There have been plenty of high-profile examples of sudden cardiac arrest in young people, but I want to speak about a case brought to my attention by one of my constituents, Maureen, who was the aunt of Clarissa Nicholls. Clarissa was studying French and Italian at the University of Cambridge. She was a keen runner and hockey player. Just days before her 21st birthday in May 2023, she collapsed and died while hiking in France with friends. It was later found that she had an undiagnosed life-threatening condition: arrhythmogenic cardiomyopathy. In June 2024, Clarissa was posthumously awarded a first-class honours degree from the University of Cambridge.

I have had the honour of meeting Clarissa’s mum Hilary, both privately and at a recent event in Westminster held by the Cardiac Risk in the Young campaign. I thank my hon. Friend the Member for North West Leicestershire (Amanda Hack) for organising that event. Hilary said:

“Despite a journey cut tragically short we want to celebrate her achievements alongside her cohort, as it should have been. We know that we would have been very proud of her today and we remain proud of her dedication, determination and resilience as she set out to be the very best she could be.”

[Fleur Anderson (Putney) (Lab)]

I congratulate my hon. Friend on securing this debate. I have also met Hilary, Clarissa’s mum, and heard about her death and the fact that a simple electrocardiogram test can save lives. It is chilling to think that my daughters could face this. Does my hon. Friend agree that it is shocking that exercise can triple the risk of sudden cardiac death, but 80% of cases show no symptoms at all? The Government could act now to issue clear guidance, as we have done on concussion, and encourage and enable more young people to have the simple test that could save so many lives.

[Chris Vince]

I do agree with my hon. Friend. Clarissa was a young girl who was very involved in sport. There is no reason why young people with these conditions cannot continue to take part in sport, as long as they are aware of their condition and able to take the necessary precautions.

Hilary said that her daughter

“put everything into her studies, the friends she made here and the staff that supported her along the way including while she was on her year abroad. We are grateful for the happy times she clearly took away with her to the next life.”

When I applied for and secured this Adjournment debate, what really struck me was the number of people who came up to me and shared their personal experiences. In fact, only this morning, two Doorkeepers shared their experiences of this condition. I pay tribute to one of those Doorkeepers, Kieron, whose son Connor—who was born on 13 January 1994—died in 1995 at only 14 months old. When the post-mortem was conducted, it was found that he died of sudden cardiac death through a thickening of a heart muscle. That was over 30 years ago, but I know from talking to Kieron the huge impact it has had on his life; he will always carry that loss with him. It is important that we recognise how long we have been aware of these issues, and that it is time to talk about what action we can take.

This morning, I was in my constituency of Harlow, talking to one of our headteachers, Vic Goddard, who is the head of the Passmores co-operative learning community. He spoke about a young boy dying of cardiac arrest during his time as a PE teacher, and feeling so strongly that every school he works in should have a defibrillator. Again, having spoken to some of the staff in this place, I want to emphasise the huge difference that access to a defib can make to survival chances.
