Self-reported family history underestimates heart attacks among close relatives

MedicalXpress | ماي 20, 2026

A new study from Karolinska Institutet shows that people's own reports of heart attacks in the family only partially correspond with register data. The findings suggest that heart attacks among relatives are often underreported, particularly for events occurring early in life. The results, published in European Journal of Epidemiology, show that the agreement between self-reported data and register data was only moderate.
