ECG-Based Cardiovascular Risk Prediction Model
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing cardiovascular disease risk, such as pooled cohort equations, suffer from low accuracy and miscalibration, and fail to effectively utilize electrocardiogram (ECG) data for long-term risk prediction, limiting their ability to inform clinical interventions.
Innovation Solution
A computational model, such as a deep neural network or convolutional neural network, is trained on ECG data to predict cardiovascular disease events over extended timelines, combining with traditional risk scores to provide a more accurate and stratified risk assessment for patients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional pooled cohort equations are used for cardiovascular risk assessment, then the method is simple and easy to implement, but the accuracy and calibration of risk prediction is poor
Solution Approach 1:
The patent combines traditional pooled cohort equations with ECG data analysis and machine learning models to create a hybrid risk assessment system. This merging approach integrates the simplicity of traditional methods with the predictive power of ECG-based computational models, thereby improving overall risk prediction accuracy while maintaining reasonable implementation complexity
Solution Approach 2:
The patent introduces ECG data as an intermediary element that bridges traditional risk factors and outcome prediction. ECG provides additional physiological information that mediates between simple demographic/clinical data and complex disease risk, enhancing prediction accuracy without requiring direct complexity in the final risk score calculation
2Reliability
If ECG data is not utilized in risk assessment, then the assessment method remains simple, but long-term cardiovascular risk prediction capability is limited
Solution Approach 1:
The patent performs preliminary analysis of ECG data through automated computational models that process the electrocardiogram information before integration with traditional risk factors. This preliminary processing extracts relevant predictive features from ECG waveforms, enabling reliable long-term risk prediction while managing complexity through staged analysis
Solution Approach 2:
The patent replaces manual interpretation of ECG data with automated computational models and machine learning algorithms. This substitution eliminates the need for complex manual ECG analysis while capturing subtle patterns in the data that improve long-term risk prediction reliability
