Abstract
SUMMARY
Primary PCI is the preferred reperfusion strategy used in patients
with acute STEMI to prevent progression of myocardial necrosis.
Besides the advantages of this strategy, there are situations in which
myocardial reperfusion is not restored to its optimal level.
Angiographic no-reflow phenomenon, a reduced coronary
antegrade flow (TIMI flow grade ≤ 2 ) without mechanical obstruction
after recanalization, predicts poor LV functional recovery and survival
in the early phase of STEMI99.
The no-reflow phenomenon is critical and, if not reversed,
causes a high rate of morbidity and mortality. It was demonstrated that
the no-reflow phenomenon after primary PCI is a strong predictor of
death extending to up to 5 years after the acute event in patients with
STEMI.179
Although the predisposing factors of the no-reflow phenomenon
were investigated, there is little data about clinical and procedural
predictors of this phenomenon.
The aim of this study was to evaluate the CHA₂DS₂-VASc HSF
Score as a predictor of no-reflow in patients who underwent primary
percutaneous intervention.
The present study was conducted on 100 patients admitted with
STEMI and treated with 1ry PCI at cardiovascular medicine
department Tanta University Hospitals within 6 months from June
2018 to December 2018. Patients were divided into 2 groups according
