Heart Disease Detection Methods: Machine Learning, Biomarkers, and Signal Analysis
Machine Learning-Based Heart Disease Detection
Machine learning (ML) has become a leading approach for detecting heart disease, offering high accuracy and efficiency. Various ML algorithms such as Support Vector Machine (SVM), XGBoost, Random Forest, Logistic Regression, K-Nearest Neighbors (KNN), Naïve Bayes, Decision Trees, and Artificial Neural Networks (ANN) have been widely used to predict and diagnose heart disease using clinical data and patient records 1346+4 MORE. These models often utilize feature selection techniques to improve accuracy and reduce irrelevant data, with some studies highlighting the effectiveness of hybrid and ensemble models, such as stacking and bagging, for even better performance 1468+1 MORE.
Recent research shows that optimized models like XGBoost and CatBoost can achieve very high diagnostic accuracy, with some studies reporting accuracy rates above 98% and F1-scores above 90% 136. Feature selection algorithms, such as Relief, Minimal Redundancy Maximal Relevance, and novel methods like fast conditional mutual information, further enhance the performance of these classifiers 49. Ensemble techniques, which combine multiple models, have also demonstrated improved accuracy and robustness in early detection, especially for coronary heart disease .
Biomarker Detection for Cardiovascular Disease
Detection of specific biomarkers in blood samples is another important method for diagnosing heart disease. Key biomarkers include cardiac troponin I (cTnI), C-reactive protein (CRP), brain-type natriuretic peptide (BNP), and heart fatty acid binding protein (H-FABP) . Advanced detection platforms, such as spin exchange relaxation-free (SERF)-based microfluidic systems, allow for rapid, sensitive, and multiplexed detection of these biomarkers. These magnetic detection methods are stable, noninvasive, and can detect very low concentrations of biomarkers, improving early diagnosis and clinical decision-making .
Heart Sound and Signal Analysis
Analysis of heart sounds and electrocardiogram (ECG) signals remains a standard noninvasive method for heart disease detection. Traditional approaches use window-based feature extraction from heart sound recordings, but recent advancements combine short-term and long-term features to improve classification accuracy by up to 10% . ECG analysis is also a routine tool in clinical settings for early evaluation and diagnosis of heart failure and other cardiac conditions .
Data Mining and Hybrid Approaches
Data mining techniques, often combined with artificial intelligence, are used to extract meaningful patterns from large clinical datasets. Hybrid approaches, such as combining autoencoders with neural networks, have shown to provide more robust and optimized solutions for heart disease detection compared to traditional methods . These methods help in handling large and complex datasets, improving prediction accuracy, and supporting clinical decision-making.
Conclusion
Heart disease detection methods have evolved significantly, with machine learning and data mining techniques now playing a central role in early and accurate diagnosis. Advanced algorithms, feature selection methods, ensemble models, and hybrid neural network approaches have all contributed to improved diagnostic performance. Additionally, sensitive biomarker detection platforms and enhanced signal analysis techniques further support timely and effective heart disease identification. These innovations collectively offer clinicians powerful tools for early intervention and better patient outcomes 1234+6 MORE.
