Abstract:
ObjectiveTo evaluate the safety and efficacy of firofiban in gerontal patients with acute coronary syndrome(ACS). MethodA total of 106 elderly patients with ACS admitted form December 2006 to June 2008 were enrolled in a prospective case-control study. Patients were divided into percutaneous coronary intervention (PCI) group and medicine group. Both groups were randomly divided into two sub-groups, tirofiban sub-group and placebo sub-group. Patients in the PCI group received tirofiban infused in dose of 10 μg·kg- within 3 minutes as loading dose before operation and then an infusion of 0.15μg'kg-1·min-1 as maintenance dose for 24～36 hours. In medicine group,the loading dose was 0.4 μg·kg-1·min-1×30 min and the maintaining dose was 0.1 μg·kg-1·min-1×48 hours, The rates of major adverse cardiac events (MACE) consisting of death, myocardial infarction or refractory ischemia during hospital stay stay and 30 days' follow-up, bleeding rates TIMI grade, corrected TIMI frame count (CTFC) and myocardial blush grade(MBG) after PCI were compared between sub-groups of PCI group. ResultsThe basic clinical data were similar among the sub-groups. In medicine group,the MACE rate during 30 days' follow-up was much lower in the tirofiban sub-group than in the placebo sub-group (12.0% vs. 36.4 %, P < 0.05). In comparison with medicine group, in PCI group, there were fewer TIMI frames [(23.5 ±5.1) frames vs. (31.4±5.2) frames, P < 0.01] and higher percentage of myocardial blush grade 3(64.3% vs. 29.0%, P < 0.01) in firotiban sub-group of PCI group. No significant differences in bleeding rates were found between all sub-groups. ConclusionsTirofiban is safe and effective in gerontal ACS patients with blood flow and reperfusion improved.
