2. NEED FOR THE STUDY
• A study indicate that the prevalence of Reinfarction
has increased in urban areas from about 2% in 1960 to 10.5%
in 2000, while in rural areas it is increased from 2% in 1970 to
4.5% in the year of 2000. In urban population, the numbers
have been increased from 0.5 million in 1966 to 14.1 million in
the year of 2000. In Rural population the numbers have been
increased from 14.1 million in 1970 to 15.7 million in 2000.
Thus epidemiological study has shown that in 2005, 29.8
million Reinfarction patients in our country. (Gupta R, Prakash
H, et al. )
• So the researcher found that it is relevant to conduct
a study to evaluate the effectiveness of a structured teaching
programme on prevention of reinfarction among patients with
myocardial infarction in selected tertiary hospital at Chennai.
3. OBJECTIVES
• To assess the pretest knowledge regarding the prevention
of reinfarction among patients with myocardial infarction.
• To assess the effectiveness of structured teaching
programme regarding the prevention of reinfarction
among patients with myocardial infarction .
• To compare the pre-test and post-test level of knowledge
about prevention of reinfarction among patients with
myocardial infarction.
• To find out the association between the post-test level of
knowledge about the prevention of reinfarction among
patients myocardial infarction with selected demographic
variables.
4. HYPOTHESIS
• H1: There is a significant difference between the pre-
test knowledge and post-test knowledge regarding the
prevention of reinfarction among patients with
myocardial infarction.
• H2: There is a significant association between the post
test knowledge score regarding prevention of
reinfarction with selected demographic variables.

7. METHODOLOGY
CONT….
Criteria for sample selection:
Inclusion criteria:
• Patients who were between the age group of 35 to 70 years.
• Patients those who were diagnosed within one year and receiving
treatment for Myocardial Infarction in selected tertiary hospital.
• Both male and female sexes.
• Patients who were willing to participate in the study.
Exclusion criteria:
• Patients who were admitted in emergency unit and intensive care
unit.
• Patients who were seriously ill.
8. Description of the tool
• SECTION I: Demographic Data
• SECTION II: Knowledge questionnaire related to
prevention of reinfarction- The knowledge aspects
consists of 20 items. The maximum score of this tool
was 20. Each correct answer is given a score of one.
• SECTION III: Structured teaching programme
regarding prevention of reinfarction.
9. DATA ANALYSIS AND INTERPRETATION
The data has been analyzed and presented in this chapter
under the following heading:
• SECTION I: Description of sample characteristics.
• SECTION II: Level of pre test knowledge regarding the
prevention of reinfarction among patients with
myocardial infarction.
• SECTION III: Evaluate the Effectiveness of structured
teaching programme on prevention of reinfarction among
patients with myocardial infarction.
• SECTION IV: Comparison of pre-test and post-test
knowledge regarding the prevention of reinfarction
among patients with myocardial infarction.
• SECTION V: Association between post-test knowledge
score with selected demographic variables.

12. This Data indicates that 100% subjects have inadequate knowledge
scored from 1-10 in the pre -test whereas, 12% subjects have moderate
knowledge ranged from 11-15 and 88% subjects have adequate
knowledge score in post test

15. RECOMMENDATIONS
Based on the findings of the study, following
recommendations are put forth.
• The study can be done on a larger sample thereby
findings can be generalized.
• A similar study can be conducted using other teaching
strategies like using self instructional module, video
assisted teaching, etc.
• An experimental study can be undertaken with a
control group.
• A study to determine cost effectiveness of educational
materials can be conducted.
16. LIMITATIONS
• Only selected aspects regarding prevention of
Reinfarction were selected for the study.
• The researcher could not get a standardized tool
to assess the knowledge on prevention of reinfarction
among patients with myocardial infarction
17. CONCLUSION
• There are many patients who are already been affected with first
attack of MI. There may be many reasons for the inadequate
knowledge of patients with myocardial infarction, regarding the
prevention of reinfarction which can be improved upon. A nurse
who belongs to a health team is having responsibility to teach
about the prevention of reinfarction.
• A Structured teaching programme is effective in increasing the
knowledge regarding prevention of reinfarction among patients
with myocardial infarction. The findings of this present study
revealed that there is a significant increase in the post test
knowledge scores after the structure teaching programme.
• There is no significant association between the post test level of
knowledge and demographic variables of patients with
myocardial infarction except with the Educational qualification
