Purpose: This study aimed to analyze the value of remote rehabilitation guidance based on Internet technology in patients undergoing percutaneous coronary intervention. Methods: We retrospectively analyzed the clinical data of 253 patients who underwent percutaneous coronary intervention in our hospital from June 2022 to March 2023. According to different nursing methods, they were divided into a study group (remote rehabilitation guidance based on Internet technology) and a control group (routine follow-up management) with 124 and 129 cases, respectively. The compliance left ventricular diastolic dysfunction (LVDD), left ventricular end-systolic diameter (LVDS), left ventricular ejection fraction (LVEF), Seattle Angina Questionnaire (SAQ), self-rating depression scale (SDS), self-rating anxiety scale (SAS), self-care ability, quality of life (SF-36), and satisfaction of the two groups were compared. Results: The compliance of the study group was 94.35%, which was higher than that of the control group (77.52%; n = 100, χ2 = 14.683, p < 0.001). We found no difference in cardiac function between the groups before the intervention (z = –0.783, p > 0.05). After the intervention, the LVDD and LVDS of the study group were lower than those of the control group, but LVEF was higher than that of the control group (z = –9.645, p < 0.001). Before the intervention, there was no difference in the SAQ scores between the groups (z = –0.180, –1.260, and –0.543, p > 0.05). After the intervention, the scores of angina pectoris attack, disease stability, and disease cognition in the study group were higher than those in the control group (z = –13.679, –10.644, and –11.448, p < 0.001). There was no difference in SDS and SAS scores between the groups before the intervention (z = –0.008 and –0.717, p > 0.05). After the intervention, the scores of the research group were lower than those of the control group (z = –13.709 and –8.041, p < 0.001). Before the intervention, we found no difference in self-care ability between the groups (z = –0.675, p > 0.05). After the intervention, the scores of health knowledge, self-responsibility, self-concept, and self-care skills in the study group were higher than those in the control group (z = –11.644, –9.387, –12.612, and –12.012, p < 0.001). There was no difference in the SF-36 scores between the groups before the intervention (z = –0.682, –0.189, –1.124, and –0.018, p > 0.05). After the intervention, the scores of the study group were higher than those of the control group (z = –12.323, –12.163, –12.066, and –12.054, p < 0.001). The satisfaction rate of the research group was 91.94%, which was significantly higher than that of the control group (70.54%; n = 91, χ2 = 18.822, p < 0.001). Conclusions: The effect of remote rehabilitation guidance based on Internet technology is evident. It can effectively improve patients' cardiac function, enhance self-care ability, and result in high compliance with nursing care. Moreover, it can effectively reduce negative emotions and improve their quality of life. Given that satisfaction is high, it is a procedure worth promoting.
