Time of Day as a Biological Variable in Cardiovascular and Kidney Disease Research: A Scientific Statement From the American Heart Association

Paper No results yet Peer reviewed

Key takeaways

The American Heart Association is asking researchers to pay attention to the time of day when they run kidney and heart studies. Blood pressure, hormones and kidney filtering rate (eGFR) all shift over 24 hours, so a test done in the morning can read differently than the same test at night. This is guidance for scientists on how to design studies. It reports no results, and nothing changes for patients today.
