Objective To explore the application significance of drug coated balloon (DCB) in percutaneous coronary intervention (PCI) treatment. Methods A retrospective analysis was conducted on 100 patients who underwent PCI treatment in our hospital from January 2021 to January 2025. The patients were divided into a conventional intervention group (n=50) and a DCB group (n=50) based on their chosen treatment method. Treatment data from both groups were collected to analyze the effectiveness of different treatment strategies. Results There was no significant difference in the minimum lumen diameter between the two groups of patients before and immediately after surgery (P>0.05). At 6 months after surgery, the minimum lumen diameter in the conventional intervention group was significantly smaller (P<0.05); Before surgery, there was no significant difference in cardiac function indicators between the two groups of patients (P>0.05). After surgery, the LVEDd and LVESd values were higher in the conventional intervention group, while the LVEF value was lower (P<0.05); Compared with the conventional intervention group, the incidence of adverse events in the DCB group was significantly lower (P<0.05). Conclusion The application of DCB during PCI treatment can achieve satisfactory results, help improve patients cardiac function, and has high safety, with clinical application and promotion value.
