Association of Right Ventricular Infarction With Inferior Wall Myocardial Infarction

Abstract

Background:The right ventricular infarction occurs frequently in association with inferior myocardial infarction and occurs separately in rare patterns. It is related to higher morbidity and mortality rates. Aim of study:To measure the prevalence of right ventricular infarction among patients with inferior wall myocardial infarction and identifying the characteristics related to right ventricular infarction. Patients and methods: A cross sectional study carried out in CoronaryCare Unit of Azadi Teaching hospital in Kirkuk through the period from 1 st of January to31 st of October, 2017 on convenient sample of 150 inferior wall myocardial infarction patients. The data were collected by publisher through direct interview and filling of a prepared questionnaire.Results: Right ventricular infarction was present among 39.3% of patients with inferior wall myocardial infarction. There was a highly significant association between older age of self-employed patients with inferior wall myocardial infarction and right ventricular infarction (p<0.001). The main significant risk factors for right ventricular infarction among inferior wall myocardial infarction patients were family history of heart diseases and obesity (p<0.001, p=0.01). Inferior wall myocardial infarction patients with right ventricular infarction were significantly had higher complicated outcome than myocardial infarction patients with absence of right ventricular infarction (p=0.002). Conclusions:The prevalence of right ventricular infarction in inferior myocardial infarction is within normal range of previous literatures.

Incidence of Right Ventricular Infarction in Patients With Inferior Wall Myocardial Infraction

“…Stratification shows that age, gender, and duration of symptoms had no significant impact on right ventricular infarction, while diabetes mellitus (P=.046) and hypertension (P=.044) had a significant association with the incidence of right ventricular infarction. The effect of study variables right ventricular infarction in patients with inferior wall MI is shown in (Aziz, 2021); these findings were consistent with the results of the current study. Another study reported the frequency of right ventricular infarction to be 37.5%; it was also found that second and thirddegree heart block increases morbidity in those with inferior wall MI.…”
