Introduction: Cardiovascular disease is the leading cause of death in the world and India. According to World Health Organisation survivors of Myocardial Infarction (MI) are at increased risk of recurrent infarctions and have an annual death rate of 5% - six times that in people of the same age who do not have coronary heart disease. The present study was aimed at assessing the effect of video assisted teaching on knowledge and practice regarding recurrence of myocardial infarction. The objectives of the study were to assess the pre-test level of knowledge and practice in prevention of recurrence of MI among post coronary angioplasty patients, determine the effect of video assisted teaching on level of knowledge and practice in prevention of recurrence of MI among post coronary angioplasty patients and associate the selected sociodemographic and clinical data variables with pre-test level of knowledge and practice on prevention of recurrence of MI among post coronary angioplasty patients. Method: Quasi experimental approach with one group pre-test post-test design was used. Data were collected from 40 post angioplasty patients using simple random sampling. Pre-test was conducted using structured knowledge questionnaire and structured practice checklist followed by administration of video assisted teaching. Post-test was done on 15th day. Results: Majority of the samples 33(82.5%) were males. About 27 (67.5%) were having family history of cardiac and vascular disorders. Only 15 (37.5%) maintained ideal body weight. Wilcoxon signed rank test showed a highly significant (p<0.001) difference in the pre-test and post-test scores. The pre-test and posttest knowledge score were 8.05 ± 4.35 and 21.13 ± 2.289 respectively (p <0.001). The pre-test and post-test practice score were 4.75 ± 2.048 and 14.08 ± 0.829 respectively (p <0.001). Conclusion: Video assisted teaching was effective in improving level of knowledge and practice in prevention of recurrence of MI among patients who had undergone coronary angioplasty
