AI helps predict heart attacks and stroke

Artificial intelligence has been used for
the first time to instantly and accurately measure blood flow, in a study led by UCL
(University College London). The results were found to be able to predict
chances of death, heart attack and stroke, and can be used by doctors to help recommend
treatments which could improve a patient’s blood flow. Heart disease is the leading global cause
of death and illness. Reduced blood flow, which is often treatable,
is a common symptom of many heart conditions. International guidelines therefore recommend
a number of assessments to measure a patient’s blood flow, but many are invasive and carry
a risk. Non-invasive blood flow assessments are available,
including Cardiovascular Magnetic Resonance (CMR) imaging, but up until now, the scan
images have been incredibly difficult to analyse in a manner precise enough to deliver a prognosis
or recommend treatment. In the largest study of its kind, the researchers
took routine CMR scans from more than 1,000 patients and used a new automated artificial
intelligence technique to analyse the images. By doing this, the teams were able to precisely
and instantaneously quantify the blood flow to the heart muscle and deliver the measurements
to the medical teams treating the patients. By comparing the AI-generated blood flow results
with the health outcomes of each patient, the team found that the patients with reduced
blood flow were more likely to have adverse health outcomes including death, heart attack,
stroke and heart failure. The AI technique was therefore shown for the
first time to be able to predict which patients might die or suffer major adverse events,
better than a doctor could on their own with traditional approaches.
