family history of heart disease

A family history of heart disease means close blood relatives developed cardiovascular disease, especially at a young age — and it raises your own risk through a mix of shared genes and shared environment. Think of it as inherited terrain: it does not fix your fate, but it tilts the slope you are walking on.

Doctors pay most attention to premature events: heart disease in a father or brother before about 55, or a mother or sister before about 65. Such a history reflects partly inherited tendencies — toward high cholesterol, high blood pressure or clotting — and partly shared habits like diet and smoking, and it is one of the few non-modifiable risk factors used in risk scoring.

Crucially, a worrying family history is a reason to act, not to despair. You cannot change your genes, but you can act earlier and more firmly on everything you can change. In some families a strong or very early pattern points to a specific inherited condition, such as familial hypercholesterolemia, where screening relatives and early treatment make a real difference.
