With age, heart cells drastically change their function, eventually struggling to contract and release. <a href=\"https:\/\/www.nature.com\/articles\/s43587-022-00261-5\">A new study<\/a> published in <i>Nature Aging<\/i> looked deep into genetic code to unravel why this happens.<\/p>\n<p>Starting with a dozen volunteers spanning 0 to 82 years old, the team sequenced the entire genome of 56 heart muscle cells, or cardiomyocytes. The result is the first landscape painting of genetic changes in the aging heart. As we age, the heart gets hit with a double whammy at the DNA level. Cells\u2019 genetic code physically breaks down, while their ability to repair DNA erodes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scientists have long sought to untangle the mystery of how aging links to increased risk of heart disease, a predominant killer of our time.
