HDP- 01 CORONARY RISK CALCULATION

DATE:

FOR DISEASED PATIENT

AIM:
To evaluate cardio vascular risk in the patient with coronary heart

disease.
SOFTWARE:
 Heart development program software.
 Cardio vascular _risk _2software(doctorslongue.com)
PROCEDURE:
 Enter the data in to the form.
 Then click compute.
 Display the percentage of risk.
THEORY:
CORONARY HEART DISEASE
Coronary heart disease is the narrowing or blockage of the coronary arteries,
usually caused by atherosclerosis. Atherosclerosis is the buildup of cholesterol and
fatty deposits(called plaques) on the inner walls of the arteries. These plaques can
restrict blood flow to the heart muscle by physically clogging the artery or by
causing abnormal artery tone and function.
Without an adequate blood supply , the heart becomes starved of oxygen and
the vital nutrients it needs to work properly. This can cause chest pain called
angina. If the energy demands of the heart become much greater than its blood
supply , a heart attack may occur.

OUTPUT:

RESULT:
Thus the cardio vascular risk for coronary heart disease in patient has been
checked.

DEVELOP THE HOSPITAL MANAGEMENT
SYSTEM BY MYCIN SOFTWARE

AIM:
To determine the inpatient and outpatient details.
SOFTWARE:
MYCIN- Hospital Management Software.
PROCEDURE:
 Enter the details of the patients.
 Save the details in the databases.
 Generate the report.
Theory:
MYCIN is one of the most widely known medical expert system. It contains
number of rules developed by the physicians and surgeons. It is the program for
advising the physician and treating the bacterial infection of the blood. It was the
first large medical expert system that provides user the explanation and reasoning.
MYCIN conducts a question and answer dialogue such as name, age , sex,
infection area and the presence of specific symptoms relevant diagnosis of the
disease and then it recommends certain course of anti biotics. MYCIN never
compares the symptoms of two different patients.

EPILEXIA OF BLIND PATIENT
USING TEIRASIS MEDICAL SOFTWARE

AIM:
To determine the Epilexia of blind patient by TEIRASIS.
HARDWARE:
 Computer.
 Printer.
 Chart.
SOFTWARE:
 TEIRASIS medical software.
 Printer software.
THEORY:
TEIRESIAS recognizes that some of the knowledge required for the
knowledge base is inexact or rough and it succeeds in offering advice for its
correction. It also provides method for extracting the best performance out of an
expert system such as MYCIN.
TEIRESIAS's approach is to make use of the expert's ability to correct incorrect or
partially correct responses to common questions and then to focus the expert's
reply
TEIRESIAS fixes bugs by
1) Stopping the performance program when the human expert identifies an
error;
2) Working backwards through the steps in the performance program that
led to the error until the bug is found;
3) Helping the expert fix the bug by modifying the knowledge base

27

TEIRESIAS's techniques for generating explanations are based upon two
assumptions
The two assumptions used are;
1) That a recapitulation of program actions can be an effective explanation
as long as the correct level of detail is given
2) That there is some shared framework for viewing the program's actions
that will make them understandable to the user.
PROCEDURE:








Take one option.
After selecting the condition enter data in the sheet.
After that some other table will displayed.
Then enter data into the next table.
Then we will obtain the result.
Then click compute.
Probability of disease will display.

RESULT:
Thus the Epilexia of a blind person was simulated & analysed successfully
by using TERASIS medical software.
