Heart Attack Prediction with classification

Features explained

• Age
• Sex
• exng - exercise induced angina (1 = yes; 0 = no)
• ca - number of major vessels (0-3)
• cp - Chest Pain type chest pain type
  • Value 1: typical angina
  • Value 2: atypical angina
  • Value 3: non-anginal pain
  • Value 4: asymptomatic
• trtbps - resting blood pressure (in mm Hg)
• chol - cholestoral in mg/dl fetched via BMI sensor
• fbs - (fasting blood sugar > 120 mg/dl) (1 = true; 0 = false)
• rest_ecg - resting electrocardiographic results
  • Value 0: normal
  • Value 1: having ST-T wave abnormality (T wave inversions and/or ST elevation or depression of > 0.05 mV)
  • Value 2: showing probable or definite left ventricular hypertrophy by Estes' criteria
• thalach - maximum heart rate achieved
• oldpeak - Previous peak
• slp - slope the slope of the peak exercise ST segment
  • Value 0: upsloping
  • Value 1: flat
  • Value 2: downsloping
• caa - Number of major vessels
• thall - Thalium stress result ~(0,3)
• target - 0= less chance of heart attack 1= more chance of heart attack
