Abstract
SUMMARY
V involvement in acute LV MI is frequently
underestimated in the clinical setting owing to the
diagnostic limitations of the electrocardiogram (ECG) and
echocardiography.
The myocardial performance index (MPI) of RV based
on conventional Doppler echocardiography has been proven to
be a sensitive tool for detecting ”occult” RV dysfunction in
acute LV MI, but the conventional Doppler-derived MPI has a
limitation as the interval between the end and onset of tricuspid
inflow and the ejection time are measured sequentially and not
on the same cardiac cycle. In contrast, tissue Doppler imaging
(TDI) can simultaneously measure these important time
intervals on the same cardiac cycle, making the TDI derived
MPI superior in the estimation of global RV function.
Aim of the study was to assess right ventricular function
in patients presented to Ain Shams university hospital with first
acute anterior STEMI who underwent successful primary PCI.
Labs and Demographic procedural details were carefully
collected, Echocardiography was done to assess the left and
right ventricular systolic and diastolic function with special
comment on TAPSE, RVEDD, RAA, RVFAC, and tissue
Doppler derived MPI.

Summary
86
The mean age was (45.9 ± 7.60 years). Most of our study
population were males representing 55% of study population.
The most prevalent risk factor was DM (87.5%), followed by
hypertension (75%), and smoking was (67.5%).
RV Dysfunction in first Anterior MI occured in (47.5%)
of the study population using the definition of a combination of
(RV EDD >26mm, RV FAC <35%, RAA >20 cm2, and TAPSE
<16 mm), while Abnormal MPI occured in (55%) of the study
population using the definition if MPI >0.55.
(Age, Pain to door, Predilatation, Glucose level, WMSI,
Mitral E/A, Tricuspid E/A, MPI) were the independent
predictors of abnormal RV function by the combined
Echocardiography definition, while (Age, Pain to door,
Predilataion, Glucose Level, WMSI) were the independent
predictors of abnormal MPI of the RV.
