Abstract

 

Background: Mechanical revascularization of the infarct-related artery (IRA)

is the most effective treatment modality in ST-segment elevation myocardial

infarction (STEMI).No flow occurs in ∼8.8-10% of cases of primary

percutaneous coronary intervention(PCI) in STEMI patients. Our aim was to study    

actual incidence and outcome of no flow patients.

Methods: Five hundred and eighty primary PCI patients

were studied over a period of two years i.e. January 2016 to December 2017.

Drug eluting stents were used in all cases. Majority of our patients(>90%) came  6

hours  after onset of chest pain. There were many patients where there was 

no flow even after mechanical thrombus aspiration and pharmacological

vasodilator therapy. We have studied primary outcome(mortality) of no flow in

those patients.                                                                                                                

Results: There were 44 cases of  no flow in our

series(7.75%). Left anterior descending artery(LAD )was involved in eighteen

patients. Right coronary artery(RCA) was culprit in twenty four cases. Only

two cases were seen in LCX territory. One month mortality rate in no flow group

was 50% and 6.25% in successful recanalization group. One year mortality was

12.5% in successful recanalization group and 66% in no flow group.

Conclusion: Refractory no flow during primary PCI in STEMI is associated

with high mortality and morbidity. There is no established strategy to solve

this phenomenon.
