Abstract
SUMMARY
This study is a prospective observational study on
patients who presented to Ain Shams University hospital with
acute STEMI managed by primary PCI in the period of time
between 9/2013 and 1/2014.
Patients who were diagnosed to have STEMI were
subjected to thorough history taking, physical examination, 12
lead ECG, then they underwent primary PCI, labs were
withdrawn and echocardiography was done.
Study Evaluation points:
Patients’ demographic data: Age, gender, risk factors,
typical chest pain-to-door time, Door to balloon time.
Angiographic and procedural data, with emphasis on the
following:
o Number of vessels diseased, Pre-procedural TIMI flow,
direct stenting versus stenting with pre-dilatation, PTCA
only, Thrombus aspiration device employment, Mean
length and diameter of stents used, Post-procedural TIMI
flow, Mortality.
In this study we found that the mean age was 56.48years,
ranging from 18 to 80 years. Most of our study population were
males representing 84.5% of study population. The most
prevalent risk factor was smoking (75.1%), HTN was the next
(49%), the third most common risk factor was DM (36%).
Arabic Summary
93
Average Chest pain duration was 301 min while it
was41.6 min for the Door to balloon time. Door to TIMI III
time had an average of 86 min.
In our study, 139 patients underwent pre-dilatation first
(65.3%), while 74 patients underwent direct stenting (34.7%).
Thrombus aspiration device was used in 34 patients (16%).
In our study 86.5% of patients who underwent direct
stenting achieved TIMI 3 flow grade, while only 63.3% of
study population who underwent pre-dilatation achieved TIMI
3 flow.
Regarding TIMI flow after revascularization, 115patients
achieved TIMI 3 flow (77%), 44 patients had less than TIMI 3
flow (23%).
Predictors of TIMI flow in primary PCI according to our
registry:
Pre-dilatation & Door-to-balloon time had statistical
significance
To achieve optimal TIMI flow post interventions follow
the following rules:
• Reducing time elapsed from FMC to first balloon inflation.
• Setting well established protocol of management in primary
PCI to which all operators should follow regarding avoiding
pre-dilatation if possible, use of thrombus aspiration
devices.
