As Spain prepares to face Belgium in a highly anticipated clash this Friday, a familiar question resurfaces: can a football match trigger a heart attack? Scientific studies conducted over the past two decades suggest that the emotional intensity of decisive games can indeed increase the risk of cardiovascular events in vulnerable individuals. Experts are quick to clarify, however, that football itself is not the cause—it is a potential trigger in those already at risk.
The physiological response to high-stakes football is well documented. During nerve-racking matches, heart rate, blood pressure, and levels of stress hormones such as adrenaline and cortisol rise significantly. In most healthy fans, these changes are temporary and harmless. But for people with existing cardiovascular disease or multiple risk factors—such as hypertension, diabetes, or high cholesterol—that spike in stress can be enough to precipitate a heart problem.
Landmark Study from the 2006 World Cup
One of the most cited pieces of research on this topic was published in the New England Journal of Medicine after the 2006 World Cup in Germany. Researchers found that on days when the German national team played, emergency admissions for heart problems rose sharply, especially during the most tense matches. The risk of suffering a cardiovascular event increased by up to 2.7 times compared with other days. That study became a reference point for understanding how sports-related stress can affect the heart.
Subsequent research has confirmed similar patterns during other international tournaments and major sporting events, particularly when matches are decided in extra time, by penalties, or keep fans on edge until the final whistle.
Smartwatches Confirm the Trend
The latest evidence comes from Bielefeld University in Germany, whose findings were published this year in Scientific Reports. Researchers monitored more than 200 fans using smartwatches over several weeks, continuously measuring heart rate and stress levels during football matches. The study found that high-intensity games caused a clear increase in heart rate and physiological stress, especially among emotionally invested fans. Notably, reactions were far more intense when matches were watched in the stadium rather than at home.
This aligns with broader research on the health impacts of major events. For instance, the economic pressures highlighted in Europe Faces Economic Crossroads as Lagarde Urges Action Amid Global Tensions can also contribute to chronic stress, compounding the risks for vulnerable individuals.
More Than Just the Match
Cardiologists stress that football rarely acts in isolation. The risk increases when emotional stress is combined with other factors common during match days: heavy alcohol consumption, large meals, smoking, lack of sleep, and pre-existing conditions such as poorly controlled high blood pressure, diabetes, or high cholesterol. In these cases, the combination of physical and emotional stress can make arrhythmias and hypertensive crises more likely, or even trigger a heart attack in people who already have cardiovascular disease.
This interplay of factors is reminiscent of the broader health challenges Europe faces, as discussed in Spain Pushes €850 Billion EU Joint Borrowing Plan as Geopolitical Tensions Rise, where economic strain can exacerbate public health issues.
Should Fans Be Worried?
Dr José Abellán, a cardiologist, strikes a reassuring note. For the vast majority of spectators, living every second of a Spain–Belgium game poses no danger to their health. However, he advises people with a history of heart disease to avoid excesses, follow their treatment correctly, and not ignore symptoms such as chest pain, difficulty breathing, intense sweating, or discomfort radiating to the arm or jaw.
Because even though the thrill of football does not cause heart attacks on its own, science has long shown that a match at maximum tension can become the perfect trigger when the heart is already vulnerable. As Europe continues to grapple with various stressors—from geopolitical tensions to economic uncertainty—understanding these health risks becomes ever more important.
