"Heart disease runs in my family" is a starting point, not a verdict.
Almost everyone who says it means something real. But most people hold their family history in the vaguest possible terms — a grandfather, a heart attack, sometime in his sixties. That version can't do much for you.
The details are what make it useful. Who, exactly. At what age. What kind of event. And what, if anything, was known about their numbers at the time.
Those specifics change things. A first-degree relative with early cardiovascular disease is a different signal than a great-uncle in his eighties, and it may change how thoroughly your own risk deserves to be investigated — and how early.
There's also what family history can't tell you. Inherited factors like Lp(a) can travel quietly through generations without anyone ever having measured it. An unremarkable family story doesn't rule that out; it may just mean nobody looked.
Genes influence how your body handles cholesterol, inflammation, and blood pressure. They inform the plan. They don't write the ending.
