Area of Science:

  • Medical Informatics
  • Artificial Intelligence in Medicine
  • Cardiology

Background:

  • Cardiovascular disease, particularly coronary artery disease (CAD), is a leading global cause of mortality.
  • Traditional diagnostic methods like angiography are effective but costly and carry risks.
  • Machine learning and data mining offer promising avenues for developing alternative diagnostic tools.

Purpose of the Study:

  • To propose a highly accurate hybrid method for the diagnosis of coronary artery disease.
  • To improve the performance of neural networks in CAD diagnosis through weight enhancement.

Main Methods:

  • Development of a hybrid model combining genetic algorithms and neural networks.
  • Utilizing genetic algorithms to optimize initial neural network weights for enhanced performance.
  • Evaluation of the model on the Z-Alizadeh Sani dataset.

Main Results:

  • Achieved a diagnostic accuracy of 93.85%.
  • Demonstrated high sensitivity (97%) and specificity (92%) in identifying coronary artery disease.
  • The hybrid approach improved neural network performance by approximately 10%.

Conclusions:

  • The proposed hybrid method provides a highly accurate and potentially more accessible approach for coronary artery disease diagnosis.
  • Optimizing neural network weights with genetic algorithms significantly enhances diagnostic capabilities.
  • This AI-driven methodology presents a viable alternative to conventional diagnostic techniques.
