Abstract:
Objective To investigate the incidence and clinical significance of “no flow” (NF) phenomena after primary percutaneous coronary intervention (PCI) in the treatment of acute myocardial infarction (AMI). Methods ninety nine consecutive AMI patients underwent primary PCI were devided into NF group (18 cases) and non NF group (81 cases). The incidence of NF, clinical characteristics, blush grade, ST T segment elevation, peak CPK, left ventricular function and cardiac events were analysed. Results Eighteen patients demonstated NF, the incidence of NF was 18.2%. Compared with non NF, previous MI、diabetes、anterior MI and multivessel disease were more frequently observed in the cases with NF ( P 0.05). Conclusions The incidence NF after primary PCI in the treatment of AMI is 18.2%. The patients with NF show malperfusion in the myocardial microcirculation, larger infarct size, ventricular dysfunction and poor prognosis.
