Looking at over two million people born in Denmark, Chinese researchers have found a link between having a sibling die and developing heart disease early in your life. Losing a sibling during childhood and early adulthood was associated with a 17% increased risk of heart disease, with a majority of that being early-onset. This kind of study cannot directly prove that the loss of a sibling will cause you heart issues, but does point to the need for extra support for the surviving family, the researchers add.
