AI to Predict Heart Attack and Cardiac Death.
Researchers have found that machine learning, patterns and inferences computers use to learn how to perform tasks, can predict the long-term risk of heart attack and coronary death.
According to the study machine learning appears to be better at predicting heart attacks and deaths .
“Our study demonstrated that machine learning integration of clinical risk factors and imaging steps can accurately personalise the patient’s risk of having an adverse event such as heart attack or cardiac death,” said the study researchers from the Biomedical Imaging Research Institute in the US
For those findings, the research team analyzed subjects from the imaging arm of a randomised research study, who underwent coronary artery calcium scoring with available CT scans and.
Participants here were middle-aged subjects, with risk factors, but no coronary artery disease.
Researchers used machine learning to assess the risk of myocardial infarction and cardiac death in the areas, and compared the predictions with these subjects’ actual experiences over fifteen decades. Subjects here answered a questionnaire to determine risk factors and to describe their diets, exercise and marital status.
The final study consisted of 1,912 subjects after they were first studied. 7 issues presented an event of myocardial infarction death in this follow-up moment.
The subjects’ predicted machine learning scores aligned with the actual distribution of detected events. The clinical risk assessment used by cardiologists, the cardiovascular disease risk score, overestimated the risk of occasions in the higher risk categories. Machine learning didn’t.
In unadjusted analysis, high predicted machine learning threat was significantly correlated with a greater risk of a coronary event.
