Christian Eriksen, the Danish international footballer, has reported that he is recovering well at home following a recent health scare during a match against Ukraine. The 34-year-old athlete, who has a history of cardiac issues, experienced a heart episode on the pitch, but crucially, he was able to walk off after regaining consciousness—thanks to an implantable cardioverter defibrillator (ICD) that had been fitted in the wake of a previous cardiac arrest in 2021.
The Role of the ICD in Heart Health
In Eriksen’s case, the ICD functioned as a vital safety mechanism, immediately responding to a life-threatening heart rhythm. He took to social media to express gratitude, stating, “My ICD did exactly what it was designed to do: protect me when I needed it.” This small yet powerful device monitors heart rhythms and can deliver an electric shock to restore a normal heartbeat when necessary.
The ICD can be implanted under the skin, typically near the armpit, with wires leading to the heart, or it can be placed directly on the heart itself, similar to a pacemaker. In Eriksen’s situation, it is likely that the device delivered a shock to correct a dangerously fast or irregular heartbeat, allowing him to recover swiftly. Professor Aneil Malhotra, a sports cardiologist, likens the process to “switching a computer off and on again,” emphasising the effectiveness of these devices.
The Emergence of Cardiac Issues in Athletes
Cardiac arrests, though often mistaken for heart attacks, stem from different underlying issues. These may include malfunctions in the heart’s electrical system or structural problems due to inflammation or damage. While it is uncommon, cardiac issues can arise in young athletes, often with no prior symptoms. The dramatic events surrounding Eriksen’s previous cardiac arrest during the 2021 European Championships serve as a stark reminder of this reality. He was fortunate to receive immediate CPR on the field, which was instrumental in saving his life.
His experience echoes a broader concern in sports, particularly amongst younger athletes. Data indicates that sudden cardiac arrest claims the lives of approximately 12 individuals under 35 each week in the UK alone, as reported by the charity Cardiac Risk in the Young (CRY). Dr Steve Cox, the charity’s chief executive, emphasises the need for continued vigilance, noting that around 80% of cases present with no prior warning.
Screening and Prevention Strategies
To combat the risks associated with undetected cardiac conditions, screening programmes targeting young athletes have become increasingly common in the UK. These initiatives assess the heart health of individuals aged 14 to 35, identifying potential threats before they escalate. Research indicates that approximately one in 300 young people could have an underlying heart issue, highlighting the importance of preventative care.
Moreover, all players in England’s Premier and Football League are now required to undergo screening when they sign their first professional contract, with follow-ups at ages 18 and 20. These assessments employ electrocardiograms (ECGs) and ultrasounds to evaluate both the rhythm and structure of the heart, significantly enhancing early detection capabilities.
The Future of Athletes with ICDs
Returning to sport after an ICD implantation is increasingly feasible, provided athletes adhere to medical advice. Studies suggest that around 10% of individuals with ICDs may experience a shock due to abnormal heart rhythms—an indication that the device is fulfilling its intended purpose.
However, regulations differ from country to country regarding athletes with ICDs. For instance, in Italy, footballers are prohibited from competing at any level once fitted with such a device. Eriksen’s future in professional football remains uncertain, as doctors will need to investigate the causes behind his heart rhythm changes during the match.
Eriksen previously acknowledged that he was aware of the risks associated with his condition, stating in 2022, “There was always the possibility this could happen.” This sentiment encapsulates the ongoing challenge faced by athletes with heart conditions: balancing the love for their sport with the imperative of health and safety.
Why it Matters
The case of Christian Eriksen serves as a vital reminder of the often-overlooked risks associated with heart health in young athletes. With cardiac issues claiming lives at an alarming rate, the implementation of screening programmes and the advancement of life-saving technologies like ICDs are crucial. By prioritising awareness and prevention, the sports community can better safeguard the health of its players, ensuring that incidents like Eriksen’s become increasingly rare.
