摘要 目的探讨复合肝素及CD34可降解镁合金支架在急性心肌梗死后心肌血运重建中的作用。方法 18只中华小型猪结扎冠状动脉前降支建立急性心肌梗死模型,然后随机分为3组(每组6只)。A组为对照组,B组为心肌打孔+复合缓释肝素的可降解镁合金支架植入组,C组为心肌打孔+复合缓释肝素和CD34抗体的镁合金可降解支架植入组。在B和C组中,于心肌梗死区采用自制高速钻孔器由心外膜打两个直径为2 mm的透壁孔道,每个孔道内植入1枚支架。6周后,用Image Pro Plus 6.0软件量化各组的新生血管密度。于治疗前和治疗后6周,通过核素心肌灌注显像结合软件Emory Cardiac Toolbox分析心肌灌注缺损区域质量百分率,同时采用超声心动图所获取的左室舒张末容积、左室收缩末容积、LVEF等指标评估心脏的功能变化。结果治疗后6周,B组和C组的LVEF及心肌灌注缺损区域质量百分率较A组明显改善(P均<0.05);B组和C组中的新生血管密度较A组显著改善(P均<0.01)。结论复合肝素及CD34抗体的可降解镁合金支架能够显著增加缺血心肌的新生血管密度,增加缺血部位心肌的灌注,进而改善心脏的功能。
