Angina pectoris is a common clinical manifestation of coronary artery disease and remains a major public health concern, particularly in rural areas where awareness regarding cardiovascular health is limited. This study aimed to assess the effectiveness of an information booklet on knowledge regarding angina pectoris among individual male adults in a selected rural area of Western Maharashtra. A quasi-experimental one-group pre-test post-test design was adopted, and 100 male adults aged 25–50 years were selected using non-probability convenience sampling. Data were collected using a structured knowledge questionnaire administered before and after the educational intervention. The information booklet provided evidence-based information on causes, symptoms, risk factors, prevention, and management of angina pectoris. Results revealed that prior to the intervention, the majority of participants (61%) had poor knowledge, while only 3% demonstrated good knowledge. Following the intervention, 83% of participants attained good knowledge and none remained in the poor category. The mean knowledge score increased significantly from 6.4 ± 2.9 in the pre-test to 16.0 ± 2.5 in the post-test (t = 24.4, p < 0.001). Monthly income and exercise practices showed significant associations with knowledge levels. The study concludes that a structured information booklet is an effective, low-cost educational strategy for improving awareness regarding angina pectoris among rural male adults and can be integrated into community-based cardiovascular health promotion programs.
