OBJECTIVE: To probe into the clinical efficacy and key points of nursing of reteplase combined with low molecular heparin in treatment of acute ST elevation myocardial infarction (STEMI). METHODS: 87 patients with STEMI from Mar. 2014 to Jul. 2016 were selected and divided into observation group ( n =47 ) and control group( n = 40 ) via random number table. The observation group was treated with reteplase combined with low molecular heparin， and the control group was treated with reteplase combined with unfractionated heparin. The clinical efficacy and the complications during acute phase of the two groups were compared， and the key points of nursing before and after thrombolysis were summarized. RESULTS： There were no significant differences in clinical recanalization rates， recanalization rates of vascular， incidences of severe arrhythmia and mortality between two groups (P > 0. 05). The incidences of post-infarction angina， hypotension and hemorrhage of observation group were respectively 8.51% (4/47)，12. 77% (6/47)，8. 51% (4/47)，which were significantly lower than those of control group [20. 00% (8/40)， 30. 00% (12/40)，52. 50% (21/40)]，with statistically significant difference (P < 0. 05). CONCLUSIONS： The combination of reteplase with low molecular heparin and effective nursing in treatment of STEMI can reach rather satisfactory recanalization rate of the coronary artery，reduce complications and improve the prognosis of patients.
