Insights
This study introduces a machine learning model to predict high-risk coronary artery disease (CAD) using image data. The model accurately identifies coronary segments needing Percutaneous Coronary Intervention (PCI) stenting.
Area of Science:
- Cardiology
- Medical Imaging
- Machine Learning
Background:
- Cardiovascular diseases are a leading cause of global mortality.
- Diagnosing Coronary Artery Disease (CAD) often involves costly or risky imaging methods.
- Machine learning offers potential for early CAD risk prediction and event forecasting.
Purpose of the Study:
- To develop a classification scheme for predicting Percutaneous Coronary Intervention (PCI) stenting placement using image-based data.
- To classify coronary segments into high and low CAD risk categories based on PCI needs.
Main Methods:
- Implementation of a gradient boosting classifier.
- Integration with the EasyEnsemble technique for handling class imbalance.
- Utilizing image-based features for classification.
Main Results:
- The classification model predicts PCI stenting placement.
- The model classifies coronary segments into high and low CAD risk.
- Combining coronary degree of stenosis and fractional flow reserve achieved 78% accuracy.
Conclusions:
- Image-based features are crucial for CAD risk assessment.
- The developed model shows promise in identifying patients who may require PCI.
- Accurate prediction of PCI needs can aid in early intervention for cardiovascular disease.
Abstract:
Cardiovascular diseases are nowadays considered as the main cause of morbidity and mortality worldwide. Coronary Artery Disease (CAD), the most typical form of cardiovascular disease is diagnosed by a variety of imaging modalities, both invasive and non-invasive, which involve either risk implications or high cost. Therefore, several attempts have been undertaken to early diagnose and predict either the high CAD risk patients or the cardiovascular events, implementing machine learning techniques. The purpose of this study is to present a classification scheme for the prediction of Percutaneous Coronary Intervention (PCI) stenting placement, using image-based data. The proposed classification model is a gradient boosting classifier, incorporated into a class imbalance handling technique, the Easy ensemble scheme and aims to classify coronary segments into high CAD risk and low CAD risk, based on their PCI placement. Through this study, we investigate the importance of image based features, concluding that the combination of the coronary degree of stenosis and the fractional flow reserve achieves accuracy 78%.
