Abstract:
Objective To investigate the clinical and angiographic characteristics of no reflow phenomenon after primary percutaneous coronary intervention (PCI) with acute myocardial infarction (AMI).Methods A total of 319 patients with AMI undergoing primary-PCI was divided into no-reflow and normal reflow groups.The incidence of no-reflow phenomenon,the clinical date,angiography findings,and surgical date were compared between two groups.Results No-reflow phenomenon occurred in forty(13.4％)of the patients after primary PCI.There was dramatic difference in combined hyperlipidemia,angina pectoris history before AMI,heart function ≥2 grades on admission,the length of the vascular lesions,vascular stenosis degree,blood clot load level,coronary artery opening time,and the expansion of the balloon between no-reflow and normal blood flow groups.Multiple logistic regression analysis identified that angina pectoris history before AMI,heart function classification on admission,high thrombus burden,the expansion of the balloon,and coronary artery opening time on angiography as independent predictors of no-reflow phenomenon.Conclusions The occurrence of no-reflow phenomenon after primary PCI was associated with high cholesterol history,no history of pre-infarction angina,heart function classification on admission,long vascular lesions,narrow degree of heavy,blood clots in the high load,coronary artery opened long time,and the expansion of the balloon more frequently.
