Abstract：Objective: To analyze the effects of nicorandil on TIMI classification, coronary microcirculation, and serum inflammation indexes after CABG (coronary artery bypass surgery) in patients with ACS (acute coronary syndrome). Methods: 86 patients with ACS admitted to our hospital from January 2018 to December 2019 were grouped with random number table (43 cases in each group). The basic treatment group was given routine clinical treatment after CABG surgery, and the nicorandil group was treated with nicorandil more than the treatment group, and the TIMI blood flow classification, coronary microcirculation, serum inflammation indicators, and adverse reactions were compared between the two groups. Results: After 4 weeks of treatment, the TIMI grade of the nicorandil group was significantly better than that of the basic treatment group. The IMR, IL-6, hs-CRP, and TNF-a indexes of the nicorandil group were significantly lower than those of the basic treatment group. The differences were statistically significant (P<0.05). The incidence of adverse reactions (9.30%) in the nicorandil group was compared with the basic treatment group (6.98%), and the difference was not statistically significant (P>0.05). Conclusion: Nicorandil applied to patients with ACS after CABG surgery can effectively improve coronary reperfusion, reduce inflammation, and has fewer adverse reactions, which is worthy of reference.
