Loss of Male Sex Chromosome Leads to Earlier Death for Men

Article here. Excerpt:

'The loss of the male sex chromosome as many men age causes the heart muscle to scar and can lead to deadly heart failure, new research from the University of Virginia School of Medicine shows. The finding may help explain why men die, on average, several years younger than women.

UVA researcher Kenneth Walsh, Ph.D., says the new discovery suggests that men who suffer Y chromosome loss—estimated to include 40% of 70-year-olds—may particularly benefit from an existing drug that targets dangerous tissue scarring.'
