title="Onset of heart disease failure prediction",

description ='''    Description
Cardiovascular diseases (CVDs) are the number 1 cause of death globally, taking an estimated 17.9 million lives each year, which accounts for 31% of all deaths worlwide. 
Heart failure is a common event caused by CVDs and this dataset contains 12 features that can be used to predict mortality by heart failure.
Most cardiovascular diseases can be prevented by addressing behavioural risk factors such as tobacco use, unhealthy diet and obesity, 
physical inactivity and harmful use of alcohol using population-wide strategies. People with cardiovascular disease or who are at high cardiovascular risk 
(due to the presence of one or more risk factors such as hypertension, diabetes, hyperlipidaemia or already established disease) 
need early detection and management wherein a machine learning model can be of great help.

More details about the Inputs taken and how they needed to be taken are given below:

     * Age (Your Age)
     * Sex (Male (1) or Female (0))
     * Chest pain 
        1) ASY - 0
        2) ATA - 1
        3) NAP - 2
        4) TA - 3
     * RestingBP - Resting Blood pressure
     * Cholesterol - Cholesterol level as of now
     * FastingBS - Fasting blood sugar 
        1) Above 120,Type 1
        2) Below 120,Type 0
     * RestingECG 
        1) LVH - 0
        2) NORMAL - 1
        3) ST - 2
     * MaxHR - Is the maximum heart rate recorded
     * ExerciseAngina - Do you have Angine while you exercise 
        1) No - 0
        2) Yes - 1
     * Oldpeak -  ST depression induced by exercise relative to rest.
     * ST_Slope - The ST segment shift relative to exercise-induced increments in heart rate
        1) Down - 0
        2) Flat - 1
        3) UP - 2
