Abstract:
Objective To explore the clinical values of ST-segment changes in ST-segment elevated myocardial infarction (STEMI) patients within 24 hours after primary percutaneous coronary intervention (PCI).Methods A total of 225 patients with STEMI underwent primary PCI were enrolled,the ST segment resolution 1 hour after PCI was calculated and the patients were divided into group A (n =135,∑STE resolved ≥ 50％) and group B (n =90,∑STE resolved ＜ 50％).The patients in group B were further divided into group C (n =56,∑STE resolved ≥ 50％) and group D (n =34,∑STE resolved ＜ 50％) according to the ST segment resolution at 24 hours after PCI.TIMI flow after PCI,in-hospital major adverse cardiac events(MACE) and cardiac function about 7 days post PCI were analyzed.Results Data between group A and group B were similar except the incidence of pre-PCI Killip ≥ Ⅱ was significantly higher in group B than in group A (37.8％ (34/90) vs.17.0％ (23/135),P ＜ 0.05).Incidence of complicated diabetes (P ＜0.05),pre-PCI Killip≥ Ⅱ (55.9％ (19/34) vs.26.8％ (15/56),P ＜0.05) and multivessel disease(70.6％ (24/34) vs.35.7％ (20/56),P ＜ 0.05) were significantly higher in group D than in group C.TIMI 3 and the opening time of IRA was similar between group A and group B and between group C and group D.The incidence of in-hospital MACE was significantly higher in group B than in group A (14.4％ (13/90) vs.3.0％ (4/135),P ＜ 0.05) which was similar between group C and group D.Conclusion Early (1 hour) but not late (24 hours) ST resolution post PCI is related to a favorable clinical outcome in STEMI patients.
