Objective This study aims to explore the clinical effect of evidence-based nursing intervention on elderly patients with coronary heart disease and angina pectoris. The study compares the effects of evidence-based nursing and routine nursing to evaluate its impact on patient symptom relief, quality of life, and complication control. Methods 60 elderly patients with coronary heart disease and angina pectoris admitted to our hospital from March 2023 to March 2024 were selected and randomly divided into an observation group and a control group, with 30 cases in each group. The observation group adopted evidence-based nursing intervention, including personalized nursing plans, health education, psychological support, etc.; the control group received routine nursing intervention. The main evaluation indicators are the number of angina pectoris attacks, attack duration, quality of life score (SF-36) and the incidence of adverse reactions. Research data were analyzed using SPSS 22.0 statistical software, using t test and chi-square test. P<0.05 was considered a statistically significant difference. Results the study showed that the number of angina pectoris attacks in the observation group was significantly reduced, with the average number of attacks per month reduced from 4.8±1.2 times before intervention to 1.9±0.8 times (P<0.01); the duration of attacks was shortened, from 15.6±3.5 times on average. minutes dropped to 8.4±2.1 minutes (P<0.01). In addition, the SF-36 quality of life score of patients in the observation group was significantly improved, with a post-intervention score of 75.3±6.2 points, compared with 62.7±5.9 points in the control group (P<0.01). In terms of the incidence of adverse reactions, the observation group was significantly lower than the control group (P<0.05). The incidence of adverse reactions in the observation group was 10%, and that in the control group was 26.7%. Conclusion Evidence-based nursing intervention can effectively improve the clinical symptoms of elderly patients with coronary heart disease and angina pectoris, improve their quality of life, and reduce the incidence of adverse reactions. This nursing model provides more comprehensive nursing support for elderly patients with coronary heart disease and is recommended to be widely promoted and applied in clinical care.
