4. Introduction
▪ The heart, a hollow muscular organ, is
located in the center of the chest.
▪ Heart disease refers to conditions that
involve narrowed or blocked blood
vessels]
▪ It can lead to a heart attack, chest pain
(angina) or stroke
▪ This data set will help to detect if a
person has a cardiovascular disease or
not

5. Age
▪ Increasing age may increase a person's risk of heart disease
▪ Aging can cause changes in the heart and blood vessels
▪ People age 65 and older are much more likely than younger people to suffer
a heart attack, to have a stroke and heart failure

6. Sex
▪ Clinical studies of Coronary Heart Disease(CHD) have found that women with
CHD are usually older than men
▪ Men usually have a 2-fold higher incidence of coronary heart disease and
related mortality than women

7. Chest Pain
▪ Chest pain is caused when heart muscle
doesn't get enough oxygen-rich blood
▪ Chest pain has many possible causes,
all of which need medical attention
Type Value
Typical angina 1
Atypical angina 2
Non-anginal pain 3
Asymptomatic 4

8. Resting Blood Pressure
▪ Blood pressure is the pressure of blood
pushing against the walls of arteries
▪ Blood pressure is measured using two
numbers: Systolic and Diastolic
▪ High blood pressure, also called
hypertension, is blood pressure that is
higher than normal
Systolic Diastolic Result
less than 120
mm Hg
less than 80
mm Hg
Normal
120–129 mm
H
less than 80
mm Hg
Prehypertensi
on
130 mm Hg or
higher
80 mm Hg or
higher
Hypertension

9. Serum Cholesterol
▪ Cholesterol is a type of fat. It’s three
types:
1. LDL (“bad” cholesterol)
2. HDL (“good” cholesterol)
3. Triglycerides
▪ Measuring LDL, HDL and triglycerides
will give us a number called serum
cholesterol.
Age and sex Total serum
cholesterol(mg/dl)
All aged 19 years and
younger
170 mg/dl at most
Females aged 20
years and older
125–200 mg/dl at
most
Males aged 20 years
and older
125–200 mg/dl at
most

10. Fasting Blood Sugar
▪ Measuring blood sugar after an
overnight fast (not eating)
▪ This helps to detect diabetes
Type Fasting Blood Sugar
Test
Normal 99 mg/dL or lower
Prediabetes 100 to 125 mg/dL
Diabetes 126 mg/dL or higher

11. Resting Electrocardiographic Results
▪ An electrocardiogram (ECG) is a medical
test that detects heart problems by
measuring the electrical activity
generated by the heart as it contracts
▪ No movement is allowed in resting ECG
during the test, as electrical impulses
generated by other muscles may
interfere with those generated by heart
Type Value
Normal 0
Having ST-T wave
abnormality
1
Hypertrophy 2

12. Maximum Heart Rate
▪ Heart rate is the number of times the heart
beats in the space of a minute
▪ Heart is a muscular organ in the center of
the chest. When it beats, the heart pumps
blood containing oxygen and nutrients
around the body and brings back waste
products
Age
Normal heart rate
(bpm)
Up to 1 month 70 to 190
Over 10 years 60 to 100

13. Exercise Induced Angina
▪ Angina is caused when heart muscle
doesn't get enough oxygen-rich blood
▪ Exercise and stress can induce angina
Induced Angina Value
Yes 1
No 0

14. Old Peak
▪ ST depression refers to a finding on an
electrocardiogram, wherein the trace in
the ST segment is abnormally low below
the baseline
▪ ST depression less than 0.5mm is
accepted
▪ ST depression greater than 0.5mm is
considered as pathological

15. The Slope Of The Peak
Type Value
Upsloping 1
Horizontal 2
Down sloping 3

16. Thalassemia
▪ Thalassemia is inherited blood
disorders characterized by
decreased hemoglobin production
▪ Symptoms depend on the type and can
vary from none to severe
▪ Fixed defect means no blood flow in
some part of the heart
▪ Reversible defect means a blood flow is
observed but it is not normal
Type Value
Fixed defect 1
Normal blood flow 2
Reversible defect 3
