Cellular aging increases a person's risk of having a heart attack and dying early, according to new research. Lifestyle choices, such as smoking, alcoholism and obesity, damage the body's chromosomes and cause cells to age. The link between this process and heart attack and early death has been suspected for some time, but a population study in Denmark has identified a direct link. What's more, the investigation has unearthed a means by which to test the cellular health of a person to predict their likelihood of developing cardiac complications. Analysing nearly 20,000 Danes, researchers at the University of Copenhagen isolated an individual's DNA to measure cellular aging. Researchers have now called for further research into the molecular mechanism of cell death that causes heart attacks. A previous study suggested that depression is also an accelerator of immune cell aging, which can put people at risk of serious diseases, specifically if left untreated.
