Footballer Dies After Chest Blow; Israeli Doctor Explains Rare Heart Condition

A tragic incident occurred on November 3rd when Jesús de Miguel, a forward for the Spanish club Tenerife, died a day after collapsing on the field. He sustained a blow to the chest from an opposing player's knee, which reportedly caused his heart to stop. While medics were able to restore his heartbeat in the ambulance, his condition deteriorated in the hospital, leading to his death.

Such impacts are not uncommon in football, but usually, players recover quickly. Dr. Anat Berkovich, head of the Cardiology Department at Sheba Medical Center, explained to Ynet that the cause of sudden loss of consciousness after such a chest trauma can be commotio cordis, a rare condition. This occurs when a blunt force to the chest, hitting a specific point during a narrow window of the cardiac cycle, disrupts the heart's electrical conductivity, potentially leading to ventricular fibrillation. However, the club's statement on de Miguel's death did not specify a diagnosis, and it was not officially confirmed that this condition was the cause.

Commotio cordis, essentially an electrical disturbance in the heart caused by a severe blow, prevents the heart from pumping blood effectively. Doctors observe this more frequently in young, healthy individuals due to their more flexible chests. The American Heart Association estimates the vulnerable period to be only 20-40 milliseconds, making the coincidence of impact point and cardiac phase crucial for this rare event. Similar blows in everyday life can cause arrhythmia, coronary artery damage, or dissection, sometimes leading to heart attack or muscle rupture, comparable to injuries seen in car accidents.

Immediate action is critical if someone collapses after a chest blow. Checking for breathing is paramount; if absent or abnormal, it indicates cardiac arrest. Prompt CPR and the use of a defibrillator can be life-saving. Dr. Berkovich stresses the importance of calling emergency services (101 in Israel) and starting chest compressions immediately, aiming for 100-120 compressions per minute. A defibrillator, which analyzes heart rhythm and advises on electrical shock delivery, can be used by anyone. Studies show that CPR initiated within 3 minutes of cardiac arrest dramatically increases survival rates, from 40% to just 5% if delayed beyond that.

Even after pulse restoration, the brain is at risk due to lack of oxygen during the cardiac arrest. Dr. Berkovich noted that prolonged oxygen deprivation could cause severe neurological damage, and brain swelling might further compromise vital functions. The possibility of a head injury, mentioned in some reports, could also have contributed to de Miguel's neurological decline, either independently or in conjunction with the cardiac event.

Underlying heart conditions like coronary artery anomalies or hypertrophic cardiomyopathy can also cause sudden collapse in athletes. These conditions, sometimes hereditary or congenital, can restrict blood flow or impair the heart's pumping function. While regular medical screenings for athletes aim to detect such issues through questionnaires, ECGs, and echocardiograms, they cannot guarantee the identification of all hidden problems, as commotio cordis can affect even a healthy heart. Therefore, preparedness for emergencies, resuscitation skills, and quick defibrillator access remain vital. FIFA data analysis from 2014-2018 showed high survival rates (around 85%) among footballers who received prompt defibrillator assistance after collapse.

Regarding protective gear, Dr. Berkovich stated that while some equipment might reduce risk in certain sports, there are no general recommendations for chest protection for footballers. She emphasized that the most reliable protection lies not in equipment, but in the preparedness and prompt, correct actions of those present.
