Traditional and Novel Predictive Models of the Heart Disease\n\nJiayi LiangD  \nFaculty of Art and Science,University of Toronto,Toronto,Ontario,Canada  \nKeywords:Heart Disease Prediction,Decision Trees,Logistic Regression,Support Vector Machines,WeightedAssociative Rule Mining.  \nAbstract:Considering that the leading cause of mortality worldwide is still cardiovascular disease,prompt riskassessment might facilitate proactive treatment strategies that enhance patient outcomes and lessen thefinancial burden on healthcare systems.Predicting heart disease is therefore critical to reducing mortality,reducing complications,and improving patient outcomes through early intervention.Predictive algorithmscan identify high-risk patients before symptoms appear,but traditional diagnostic techniques frequently missearly-stage disease.Machine learning techniques like K-nearest Neighbors(KNN)and Decision Trees(DT)have become more and more popular for the prediction of cardiac illness.The interpretability,accuracy,andcomputing efficiency of these models varies.Prediction accuracy has been further enhanced by recentdevelopments like Weighted Associative Rule Mining(WARM)and ensemble learning approaches(XBoost,Adaboost,and random subspace classifiers).These approaches still have issues with generalization,overfitting,interpretability of the model,and computational complexity.In order to produce more precise,individualized,and interpretable forecasts,future advancements in cardiac disease prediction are probablygoing to concentrate on hybrid models,explainable artificial intelligence(XAI),and multimodal dataintegration.With the goal of improving heart disease risk assessment with AI-driven healthcare solutions,thispaper examines both conventional and innovative predictive models,their limitations,and potential futurepaths.  \ndeath(Centers for Disease Control and Prevention,2024).Reducing the morbidity and mortality linkedto heart disease requires early detection andprevention.Accurate risk assessment and earlyidentification of heart disease continue to besignificant obstaclesdespite significantadvancements in cardiovascular medicine.Timelylifestyle changes,medication management,andfocused therapy can be made possible by identifyinghigh-risk populations before severe symptoms appear.Nevertheless,conventional diagnostic techniquesdepend on clinical history,medical competence,andcommon biomarkers like electrocardiograms,stresstests,and clinical risk assessments.These indicatorsare frequently arbitrary,inconsistent,or have littlepredictive ability to identify diseases in their earlystages.To solve these constraints,advancedpredictive models are needed for better riskstratification and tailored medication,hencepredictive models based on machine learning andartificial intelligence(AI)have become useful tools  \n## 1 INTRODUCTION\n\nCardiovascular disease(CVD)claims one life every33 seconds,making it the world's biggest cause ofmortality,according to the WHO(Centers for DiseaseControl and Prevention,2024).Heart disease,whichencompasses llnesses like coronary artery disease,heart failure,and arrhythmias,is thought to be thecause of 17.9 million deaths globally,with low andmiddle-income countries accounting for more thanthree-quarters of cardiovascular disease deaths(World Health Organization,2021).About one-fifthof deaths in the US are caused by heart disease;in2022,702,880 deaths were reported.The mostprevalent kind of heart disease among them iscoronary heart disease.In addition to mortality,heartdisease also brings a huge economic burden,withlosses of approximately $252.2 billion from heartdisease between 2019 and 2020,including medicalservices,medicines,and productivity losses due to  \nin healthcare.However,constructing reliable,interpretable,and efficient prediction models entailsovercoming hurdles such as data quality,modelgeneralizability,computing limits,and clinicaluptake.The upcoming sections will discuss fourprevalent pathological conditions of
