Heart disease is very dangerous disease in our human body. Data analysis is a process of extracting, presenting, and modeling based on information retrieved from raw sources. The dataset from UCI machine learning repository is used, and only 6 attributes are found to be effective and necessary for heart disease prediction. GNDEC, Ludhiana, India GNDEC, Ludhiana, India. We can also see that the column 'prop' appear to both have corrupted rows in them, which will need to be deleted from the dataframe. There are several types of classifiers available in sklearn to use. Analysis Heart Disease Using Machine Learning Mashael S. Maashi (PhD.)

Cardiovascular disease 1 (CVD), which is often simply referred to as heart disease, is the leading cause of death in the United States. The "goal" field refers to the presence of heart disease in the patient. However, I have not found the optimal parameters for these models using a grid search yet.
