The Chattanooga Heart Institute, the cardiac care service provider for CHI Memorial, is the latest known local health care provider to fall victim to cyber intruders who may have stolen private patient information, according to an online notice.

The notice on The Chattanooga Heart Institute website states that in April the provider identified signs its information technology network was breached and launched an investigation with the help of an outside forensics vendor.

“On May 31, 2023, The Chattanooga Heart Institute learned that the unauthorized third party obtained copies of some of the data from its systems containing confidential patient information,” the website states, noting the hackers did not retrieve data directly from the provider’s electronic medical records.

The breach occurred between March 8 and March 16, according to the website. The Chattanooga Heart Institute was the only entity within the health system affected by the attack, a CHI Memorial spokesperson said.
