Scientists have developed a new AI system that can detect and quantify the buildup of plaque in arteries, helping doctors to better predict and prevent heart attacks. The system, developed by researchers at the University of Iowa, uses deep learning to analyze images of arteries and identify the presence of plaque. Plaque is a buildup of fat, cholesterol, and other substances that can narrow arteries and restrict blood flow. It is a major cause of heart attacks and strokes..
The new AI system is able to detect plaque with a high degree of accuracy. In a study published in the journal Radiology, the researchers tested the system on images of arteries from 1,000 patients. The system was able to detect plaque with 95% accuracy, which is comparable to the accuracy of human experts..
The researchers also found that the system was able to predict the risk of heart attack in patients with plaque. In a study published in the journal JAMA Internal Medicine, the researchers followed 5,000 patients with plaque for an average of five years. They found that patients with a higher burden of plaque, as detected by the AI system, had a higher risk of heart attack..
The new AI system could help doctors to better identify patients at risk for heart attacks and to develop more personalized treatment plans. It could also be used to screen for plaque in patients who are not yet showing any symptoms..
## How the AI System Works.
The AI system uses deep learning, a type of machine learning that is particularly well-suited for analyzing images. The system was trained on a large dataset of images of arteries, both with and without plaque. The system learned to identify the features of plaque, such as its size, shape, and location..
Once the system is trained, it can be used to analyze images of arteries from new patients. The system will identify the presence of plaque and quantify its burden. This information can then be used by doctors to assess the risk of heart attack and to develop a treatment plan..
## The Future of AI in Healthcare.
The development of this new AI system is a significant advance in the field of cardiovascular medicine. It is a powerful tool that can help doctors to better identify and prevent heart attacks. As AI technology continues to develop, we can expect to see even more innovative and life-saving applications in the future..
