| Model | Accuracy | Precision | Recall | F1-Score | AUC-Score |
|---|---|---|---|---|---|
| Logistic regression | 0.820 | 0.818 | 0.844 | 0.831 | 0.913 |
| Naive bayes | 0.836 | 0.867 | 0.813 | 0.839 | 0.905 |
| Decision tree | 0.738 | 0.767 | 0.719 | 0.742 | 0.739 |
| Random forest | 0.820 | 0.889 | 0.750 | 0.814 | 0.932 |
0.932
Random Forest AUC Score
Highlighting the highest Area Under the Curve (AUC) achieved by the Random Forest model, indicating its superior ability to distinguish between classes.
-0.44
Correlation: Max Heart Rate & Disease
Strong negative correlation between maximum heart rate (thalach) and heart disease prevalence, indicating lower maximum heart rates are associated with higher disease risk.
Age-Stratified Interventions for CVD
Analysis revealed a bimodal distribution of CVD risk by age, with peaks in 37-54 age group and after 70. Middle-aged adults require stress management and health education due to lifestyle risks, while older adults need comprehensive chronic disease care. This stratification allows for targeted prevention strategies.
| Gender | Total Patients | Disease Cases | Prevalence Rate |
|---|---|---|---|
| Male | 207 | 165 | 79.7% |
| Female | 96 | 73 | 76.0% |
While males show higher absolute numbers of disease cases, females proportionally demonstrate a higher disease prevalence rate when considering their overall patient count.
