I m wondering how much there is to a family claim that we have a curse of heart problems. All have died. Our grandfather had a heart attack in his 80 s, Grandmother, mainly strokes, brother 1: diabetes, heart attack, brother 2: diabetes, heart attack, Brother 3: some minor strokes, hear attacks, blood pressure, artery problems, Mother: many strokes and high cholestrol. Not sure if the heart attacks are genetic or opportunistic. What is the relationship to strokes and the heart?
