ABOUT THE DATASET:
age - age in years
sex - (1 = male; 0 = female)
cp - chest pain type 0: Typical angina: chest pain related decrease blood supply to the heart
1: Atypical angina: chest pain not related to heart
2: Non-anginal pain: typically esophageal spasms (non heart related)
3: Asymptomatic: chest pain not showing signs of disease
trestbps - resting blood pressure (in mm Hg on admission to the hospital) anything above 130-140 is typically cause for concern
chol - serum cholestoral in mg/dl
serum = LDL + HDL + .2 * triglycerides
fbs - (fasting blood sugar > 120 mg/dl) (1 = true; 0 = false) *'>126' mg/dL signals diabetes
restecg - resting electrocardiographic results
0: Nothing to note
1: ST-T Wave abnormality
2: Possible or definite left ventricular hypertrophy
thalach - maximum heart rate achieved
xang - exercise induced angina (1 = yes; 0 = no)
oldpeak - ST depression induced by exercise relative to rest looks at stress of heart during excercise unhealthy heart will stress more
slope - the slope of the peak exercise ST segment
0: Upsloping: better heart rate with excercise (uncommon)
1: Flatsloping: minimal change (typical healthy heart)
2: Downslopins: signs of unhealthy heart
ca - number of major vessels (0-3) colored by flourosopy
colored vessel means the doctor can see the blood passing through the more blood movement the better (no clots) thal - thalium stress result 1,3: normal 6: fixed defect: used to be defect but ok now 7: reversable defect: no proper blood movement when excercising target - have disease or not (1=yes, 0=no) (= the predicted attribute)
