Abstract:
Objective To evaluate the safety and efficacy of low-molecular weight heparin on the prevention of acute closure after percutaneous intracavitary coronary angioplasty.Methods 73 patients were randomly assigned to LMWH and SH groups.All patients underwent SPECT or CAG.Myocardial ischemia and hemorrhage complication were analyzed.Results In Group LMWH,no case of hemorrhage complication occurred,and in 3 cases angina occurred within 24h after the operation,which was proved by CAG to be acute closure of target vessel (the incidence rate 8.6%) .In Group SH,gum and subcutaneous hemorrhage occurred to 2 cases within 7h after the operation,hematuria occurred to 2 cases within 12h and one case died from cerebral hemorrhage,which was confirmed by CT (the total hemorrhage incidence 13.2%).Another 4 cases in Group SH suffered from re-occurrence of angina,which was confirmed by CAG to be acute closure of target vessel (10.5%).There was significant difference in hemorrhage complication between the two groups (P0.05)。Conclusion The results suggest that LMWH is safe and effective in the prevention of acute closure after native vessel coronary angioplasty.
