Abstract:
OBJECTIVE To explore the clinical effect and safety of nicorandil combined with different doses of tirofiban in the treatment of elderly patients with acute ST-segment elevation myocardial infarction (STEMI). METHODS A total of 162 elderly patients with STEMI admitted to our hospital from June 1, 2022 to June 1, 2024 were retrospectively enrolled. All patients received percutaneous coronary intervention (PCI) and conventional treatment of STEMI, and used nicorandil (5 mg each time, tid) and tirofiban. According to the use of tirofiban, the patients were divided into conventional-dose group (n=104) and half-dose group (n=58). Patients in the conventional-dose group received an intracoronary injection of 10 μg/kg tirofiban, followed by intravenous infusion of 0.1 μg/(kg·min) for 48 h; patients in the half-dose group received an intracoronary injection of 5 μg/kg tirofiban, followed by intravenous infusion of 0.05 μg/(kg·min) for 48 h. Related indexes of PCI (the proportion of patients with grade 3 of thrombolysis in myocardial infarction, no reflow in infarct related artery, percentage decrease in total ST-segment elevation >50% on electrocardiogram 2 hours after PCI), cardiac function parameters before and after treatment (troponin I, N-terminal pro-brain natriuretic peptide contents and left ventricular ejection fraction), bleeding events during treatment (gingival bleeding, epistaxis, mucosal bleeding, gastrointestinal bleeding) and other adverse events (all-cause death, non-fatal reinfarction, hypotension, ventricular fibrillation, acute heart failure) were compared between 2 groups. RESULTS There were no significant differences in related parameters of PCI, cardiac function parameters after treatment, the incidences of gingival bleeding, epistaxis and gastrointestinal bleeding, the total incidence of bleeding events, or the incidence of other adverse events during treatment between 2 groups (P>0.05), but the incidence of mucosal bleeding in the conventional-dose group was significantly higher than the half-dose group (P<0.05). CONCLUSIONS The clinical effect of nicorandil combined with half-dose tirofiban in the treatment of elderly patients with acute STEMI is comparable to that of nicorandil combined with conventional dose of tirofiban, but the mucosal bleeding risk of the former is lower than that of the latter. Therefore, patients at risk of mucosal bleeding are more suitable to use the previous regimen.
