Heart Disease using Django in Python Projects

Heart Disease using Django in Python Projects
Abstract
Heart disease remains a leading cause of mortality worldwide, making early detection and preventive care critical. This project focuses on developing a Heart Disease Prediction system using Python and the Django web framework. The system collects patient health data, including age, gender, blood pressure, cholesterol levels, ECG results, and other relevant medical parameters, and uses machine learning algorithms to predict the likelihood of heart disease. Implemented with Python libraries such as Pandas, NumPy, Scikit-learn, and integrated with Django for web deployment, the system provides an interactive, user-friendly platform for healthcare professionals and patients. It allows real-time prediction, visualization of results, and secure management of patient data, enabling efficient and informed decision-making in preventive cardiology.
Existing System
Traditional heart disease diagnosis relies on manual clinical evaluation, lab tests, and physician expertise, which can be time-consuming, subjective, and limited in scalability. Some existing digital systems use basic statistical models or standalone ML algorithms but often lack interactive interfaces, real-time prediction capabilities, and secure data management. These systems may fail to provide accessible solutions for patients or healthcare providers who need immediate risk assessment based on structured health data.

Proposed System
The proposed system introduces a Django-based web application integrated with a machine learning backend for heart disease prediction. Patient health data is collected through forms, validated, and preprocessed using techniques like normalization, handling missing values, and encoding categorical variables. Machine learning models such as Logistic Regression, Random Forest, Support Vector Machine (SVM), or Gradient Boosting are trained on historical patient datasets to predict the presence or absence of heart disease. The Django web interface allows users to enter patient details, initiate predictions, and view results along with visual insights into contributing health factors. Python libraries such as Pandas and NumPy handle data preprocessing, Scikit-learn manages model training and evaluation, and Django facilitates web deployment and user authentication. By combining machine learning with a secure, interactive web platform, the system offers an accurate, scalable, and user-friendly solution for early heart disease detection and patient monitoring.
