Researchers in Utah say they're a step closer to developing a blood test to determine whether a person with heart disease is in imminent danger of having a heart attack. The study has identified two genetic markers that appear to decline a few days before a person suffers a heart attack. The study showed the genetic markers act like "watch dogs" and when their levels are reduced, heart disease takes a turn for the worse.
Brawn matters when it comes to teenagers' health. University of Michigan researchers say adolescents with stronger muscles have a lower risk of diabetes, heart disease and are overall more fit. The study is one of the first to show a link between strength and overall fitness. The study in the journal "Pediatrics" also reveals exercise, sports and even recreational activity that contributes to stronger muscles help reduce the risk of serious diseases during adolescence.
