The transient AKI group was older; had a higher prevalence of diabetes, lower baseline eGFR levels, and lower EF; and more frequent use of angiotensin II receptor blocker (ARB), angiotensin-converting enzyme inhibitors (ACE-Is), and angiotensin receptor neprilysin inhibitor (ARNI) than the non-AKI group. Here, ACE is linked to acute kidney injury.
