Aim: The effects of tirofiban combined with nicorandil on effective reperfusion, and the levels of interleukin-4 (IL-4) and soluble intercellular adhesion molecule-1 (sICAM-1) after percutaneous coronary intervention (PCI) for chronic coronary total occlusion (CTO) were investigated. Method: From January 1, 2017, to June 31, 2019, a total of 40 patients with CTO receiving PCI in Shandong Qianfoshan Hospital were randomly divided into a control group (treated with single tirofiban) and a cocktail group (treated with nicorandil combined with tirofiban). Effective reperfusion was compared between groups. In addition, differences in coronary serum IL-4 and sICAM-1 levels before and 10 min after the operation were compared between groups, and the incidence rates of adverse reactions were observed. Finally, patient follow-up occurred at 1 month and 6 months, and the total incidence rates of adverse cardiac events in both groups were assessed. Results: The levels of IL-4 and sICAM-1 in the cocktail group significantly decreased after the operation (P < 0.05). In addition, after the operation, significantly greater decreases in the IL-4 and sICAM-1 levels were observed in the cocktail group than the control group (P < 0.05). The Seattle Angina Scale (SAQ) score of the cocktail group, compared with the control group, showed a significant improvement after vessel opening in the patients with CTO. At the 1-month follow-up, the SAQ score of the cocktail group, compared with the control group, indicated further improvements in terms of angina attack frequency. No significant differences were observed in the incidence rates of adverse reactions between groups (P > 0.05). Conclusion: The treatment of patients with CTO undergoing PCI with nicorandil and tirofiban alleviated the inflammatory response, improved the SAQ scores, and decreased the occurrence of angina pectoris in patients. Moreover, this treatment is safe and reliable, and has important clinical significance.
