ABSTRACT
Objective To explore the double blood vessels bridge application and efficacy in multiple localized narrow of the anterior descending coronary artery.Methods The clinical data of 106 patients with multiple localized narrow of the anterior descending coronary artery were retrospectively analyzed.The patients were divided into two groups according to the operation methods.Fifty-six patients (improvement group) were conducted double blood vessels bridge on the anterior descending coronary artery,50 patients (control group) were conducted a single blood vessel bridge on the anterior descending coronary artery.Results The age,sex,body mass index,left ventricular ejection fraction,extracorporeal circulation time,endotracheal intubation time,length of hospital stay between two groups had no significant difference (P ＞ 0.05).One case in improvement group occurred angina pectoris,left ventricular size was (51 ± 6) mm,left ventricular ejection fraction was (60.8 ± 8.0)％.Nine cases in control group occurred angina pectoris,left ventricular size was(43 ± 6) mm,left ventricular ejection fraction was(55.1 ± 10.0)％.There was significant difference between two groups(P ＜ 0.05).Conclusion Double blood vessels bridge is safe and effective in multiple localized narrow of the anterior descending coronary artery.
