Abstract

Background
Right ventricular myocardial infarction (RVMI) is associated with acute inferior STEMI in 30 to 50 % of
cases and poor outcome of RVMI is usually related to profound hemodynamic and electrical complications,
which occur in approximately 50 % of cases . In contrast, RVMI associated with anterior wall myocardial
infarction in less than 10% of cases and isolated RV infarction is rare. It is the posterior RV wall that is most
frequently involved in RV infarction and nearly always in association with left ventricular posterior and posteroseptal infarction .So right precordial leads (V4R & V5R) are recommended in patients with acute inferior
STEMI, especially in the presence of hypotension and bradycardia.
Objective
To identify the prevalence of right ventricular infarction (RVI) in patients with acute inferior myocardial infarction (AIMI) within 24 hours of starting manifestations of infarction who got suitable precordial ECG and
to detect associated risk factors that increase the risk of RVI in the setting of inferior MI in Sulaimani city/
Kurdistan region/Iraq.
Methods
One hundred patients with acute Inferior STEMI were included in the study. A simplifi ed cardiovascular
questionnaire was used, and a detailed physical examination and a standard 12-lead ECG, RPLs, and cardiac
enzyme assay were carried out.
Results
Right Ventricular Infarction RVI was present in 39% of cases with acute inferior STEMI. The age group 50-
59 years was most commonly affected (57.9%). Females more commonly have RVI than males. There was
no signifi cant difference between patients with RVI and non-RVI regarding residence and occupation. Both
hypertension HT) and diabetes mellitus (DM) were the most dominant chronic diseases (55 % and 45 %,
respectively).
Conclusion
Right ventricular infarction was found in 39% of patients with acute inferior STEMI. Right precordial leads
(V4R & V5R) are recommended in patients with acute inferior STEMI, especially in the presence of hypotnsion and bradycardia.
