Bengaluru marathoner dies of suspected cardiac arrest at 31: What runners need to know about hidden heart risks

On August 9, a 31-year-old software professional from Bengaluru, Aman Deep Singh Jagade, died of a suspected cardiac arrest while completing a half-marathon in Nandi Hills. This tragic incident has raised concerns about the hidden heart risks that even well-trained athletes may face. Despite passing routine medical check-ups, such as a basic ECG and blood pressure measurement, Aman Deep's death highlights the limitations of these standard screenings.

Some heart abnormalities, like early coronary artery disease or structural heart conditions, may remain undetected during routine examinations. During a marathon, the cardiovascular system undergoes an enormous and prolonged demand, which can place considerable stress on the heart, especially when combined with factors like dehydration, heat, fatigue, or an individual's underlying susceptibility.

Certain heart conditions, such as hypertrophic cardiomyopathy or inherited rhythm disorders, may not be identified during routine heart assessments. These conditions can lead to dangerous arrhythmias, even in individuals who appear fit and healthy. Symptoms such as chest pain, fainting, or irregular heartbeats during exercise should not be ignored and warrant medical attention.

An evaluation for marathoners should include an echocardiogram, CT angiogram, exercise testing, and Holter or longer rhythm monitoring to assess potential heart abnormalities. It is crucial for runners to be aware of these hidden risks and seek appropriate medical evaluations to ensure their cardiovascular health during endurance events.
