ECG using AI can help early detection of heart condition

IANS  |  New York 

Applying (AI) to a widely available, inexpensive test can help detect a heart condition that is a precursor to heart failure, according to a new study.

Using AI with the electrocardiogram (ECG) results in a simple, affordable early indicator of asymptomatic left which is typically diagnosed with expensive and less accessible imaging tests, such as echocardiograms, CT or scans, researchers from Minnesota's said.

Asymptomatic left is characterised by the presence of a weak heart pump with a risk of overt which is associated with reduced quality of life and longevity.

The study found that AI applied to a standard ECG reliably detects asymptomatic left

"The ability to acquire an ubiquitous, easily accessible, inexpensive recording in 10 seconds - the EKG - and to digitally process it with AI to extract new information about previously hidden holds great promise for saving lives and improving health," the Mayo Clinic's said.

For the study, using digital data of 625,326 persons, the team paired ECG and transthoracic echocardiograms.

The accuracy of the AI/ECG test compares favourably with other common screening tests, such as prostate-specific antigen for prostate cancer, mammography for and cervical cytology for cervical cancer, according to the research published in the journal

In addition, patients without ventricular dysfunction, but with a positive AI screen were at four times the risk of developing future ventricular dysfunction, compared with those with a negative screen, the results showed.

"The test not only identified but also predicted risk of future disease, presumably by identifying very early, subtle ECG changes that occur before heart muscle weakness," Friedman said.

is treatable when identified, the study noted.
