Insights
Data mining techniques can predict cardiovascular diseases (CVDs) by analyzing clinical data. Optimized Decision Trees (DT) showed the most promising results for early CVD detection.
Area of Science:
- Computational intelligence
- Medical informatics
- Data science
Background:
- Cardiovascular diseases (CVDs) are a leading cause of global mortality and disability.
- Early identification of individuals at high risk for CVD is crucial for preventing premature death.
- Clinical data analysis using computational methods offers potential for improved CVD prediction.
Purpose of the Study:
- To apply Data Mining Techniques (DMTs) to clinical data for predicting cardiovascular diseases (CVDs).
- To evaluate the performance of various classification models in CVD risk assessment.
Main Methods:
- Utilized the CRossIndustry Standard Process for Data Mining (CRISP-DM) methodology.
- Applied five classifiers: Decision Tree (DT), Optimized DT, RIPPER (RI), Random Forest (RF), and Deep Learning (DL).
- Developed models using RapidMiner and WEKA tools, analyzing accuracy, precision, sensitivity, and specificity.
Main Results:
- The Optimized DT model demonstrated superior performance across all evaluation metrics.
- Optimized DT achieved 73.54% accuracy, 75.82% precision, 68.89% sensitivity, and 78.16% specificity.
- The Area Under the Curve (AUC) for the Optimized DT model was 0.788.
Conclusions:
- Data mining techniques show promise for effective CVD diagnosis.
- The Optimized DT model is a highly effective tool for predicting cardiovascular diseases.
- Further research into DMTs can enhance early CVD detection and patient outcomes.
Abstract:
Cardiovascular diseases (CVDs) aredisorders of the heart and blood vessels and are a major cause of disability and premature death worldwide. Individuals at higher risk of developing CVD must be noticed at an early stage to prevent premature deaths. Advances in the field of computational intelligence, together with the vast amount of data produced daily in clinical settings, have made it possible to create recognition systems capable of identifying hidden patterns and useful information. This paper focuses on the application of Data Mining Techniques (DMTs) to clinical data collected during the medical examination in an attempt to predict whether or not an individual has a CVD. To this end, the CRossIndustry Standard Process for Data Mining (CRISP-DM) methodology was followed, in which five classifiers were applied, namely DT, Optimized DT, RI, RF, and DL. The models were mainly developed using the RapidMiner software with the assist of the WEKA tool and were analyzed based on accuracy, precision, sensitivity, and specificity. The results obtained were considered promising on the basis of the research for effective means of diagnosing CVD, with the best model being Optimized DT, which achieved the highest values for all the evaluation metrics, 73.54%, 75.82%, 68.89%, 78.16% and 0.788 for accuracy, precision, sensitivity, specificity, and AUC, respectively.
