ABSTRACT Introduction:-Cardiovascular disorders are the world's number one cause of death. A coronary heart disease (CHD) is and accounts for most of these deaths as the most prevalent form of cardiovascular diseases. Patients with coronary heart diseases and can be asymptomatic or develop chronic stable angina. Unstable angina (UA) and myocardial infarction (MI) are more serious manifestation of coronary heart diseases and are termed acute coronary syndrome (ACS). Cardiac rehabilitation is defined as “Program is designed to limit the physiologic and psychological effect of cardiac illness and also teaches the importance of life style changes to prevent recurrence of cardiac events.”Aim: - To assess the effectiveness of self instructional module on cardiac rehabilitation in patients with coronary heart diseases.Objectives:1) To assess the existing knowledge regarding cardiac rehabilitation in patients with coronary heart diseases.2) To assess the effectiveness of self-instructional module on cardiac rehabilitation in patients with coronary heart diseases.3) To find out the association of knowledge score with selected demographic variables.Methods and Materials: The study was an interventional research approach conducted among 70 patients of coronary heart diseases from selected hospital in AcharyaVinobaBhave Rural Hospital Wardhawere used to collect data.Results: Result of the study was Mean value of pretest is 5.34 and posttest is 17.37 and standard deviation values of pretest are ± 1.29 and posttest is ±1.65. The calculated t-value is 50.88 and p-value is 0.001 and there is a substantial difference between pre-test and post-test knowledge scores interpreting successful self-instruction module on cardiac rehabilitation information in patients with coronary heart disease. Conclusion: According to the result of this study statistically interpreted that self-instruction module was successful for cardiac recovery among coronary heart disease patients.
