Artificial Intelligence-Enhanced ECGs are quicker at assessing high-risk cardiac patients and outperform current standard-of-care blood tests, reveals a new study.
Highlights :
- Shortness of breath can be due to many reasons and determining why someone has it can be challenging for the emergency department physicians
- Electrocardiogram results evaluated with artificial intelligence-based (AI) formula is a rapid and effective method to determine if shortness of breath is due to heart failure and will help assess decreased heart function
- AI-based ECG is better than standard blood tests at identifying both severe and less severe left ventricular systolic dysfunction in both men and women alike

In left ventricular systolic dysfunction (LVSD), the left ventricle is weakened and must work harder to maintain adequate blood flow to the body. The left ventricle is the largest chamber in the heart as it supplies most of the heart’s pumping power.
When emergency department physicians suspect cardiac abnormalities, an ECG which is a quick, 10-second recording of the heart’s electrical activity is performed. "An abnormal ECG raises concern about underlying cardiac abnormalities but are not specific for heart failure,"Adedinsewo said.
Standard blood tests are also done to assess the blood levels of natriuretic peptides. Elevated natriuretic peptides is a biomarker of heart failure. But its levels are also affected by obesity, age, kidney disease, severe infection, high blood pressure in the vessels that bring blood to the lungs (pulmonary hypertension), abnormal heart rhythms, and a specific heart failure medication.
In order to create AI-enhanced ECG, Mayo researchers trained computers to distinguish between ECG patterns of people diagnosed with LVSD and those without LSVD by using data on thousands of patients. Using AI software application, the standard ECG recordings can be analyzed in about ten seconds, to identify LSVD.
Benefits of AI-Enhanced ECG
AI-enhanced ECG was better than standard blood tests in identifying which patients have severe LVSD;The AI-enhanced ECG was also good at identifying patients with less severe but abnormally low pumping ability (50% or less of the blood leaving the heart with each contraction);
"AI-enhanced ECGs are quicker and outperform current standard-of-care tests. Our results suggest that high-risk cardiac patients can be identified quicker in the emergency department and provides an opportunity to link them early to appropriate cardiovascular care," Adedinsewo said.
More such prospective rather than retrospective studies are required before this becomes an acceptable practice in emergency and other departments.
