To build a machine learning model to classify patients into heart attack risk categories.
This project proves the concept that machine learning can be used to classify patients into heart attack risk categories. This is not a diagnostic tool, but a time-saving measure. This would provide very fast identification of high-risk patients without the time-consuming, manual review of records. Patients identified as high risk can be sent for further review by a doctor and have frequent follow-ups along with nutrition guidance.

**Medical Definitions 1- Angina: chest pain due to reduced blood flow to the heart muscles. There're 3 types of angina: stable angina, unstable angina, and variant angina.

2- Cholesterol: a waxy substance found in the body cells and it belongs to a group of organic molecules called lipids. There are 3 types of cholesterol; high-density lipoprotein (HDL) and it's known as the "good cholesterol", low-density lipoprotein (LDL) known as the "bad cholesterol", and very-low-density lipoproteins (VLDL) and as the name implies, they're low dense particles that carry triglycerides in the blood.
3- ECG: short for electrocardiogram, it's a routine test usually done to check the heart's electrical activity.
4- ST depression: a type of ST-segment abnormality. the ST segment is the flat, isoelectric part of the ECG and it represents the interval between ventricular depolarization and repolarization. For more details check this link: https://litfl.com/st-segment-ecg-library/.
5- Thalassemia: it's a genetic blood disorder that is characterized by a lower rate of hemoglobin than normal.
