In Hospital Outcome of Subclinical Right Ventricular Involvement in Patients with Acute Inferior Myocardial Infarction

Abstract

Objectives: This study aimed to study the in hospital outcome of subclinical right ventricular involvement (ScRVI)in patients with acute inferior wall myocardial infarction(AIMI). Patients and Methods: We conducted a short prospective studycarried out on 60 patients with acute inferior myocardial infarction, classified into two groups; patients group: AIMIwith ScRVI; inferior or infroposterior acute myocardial infarction (AMI)patients with ≥ 0.1 mV V4R elevation, and control group: AIMI without ScRVI; inferior or infroposterior AMI patients without ≥ 0.1 mV V4R elevation. We followed up both groups during their hospital stay and compared both groups regarding development of complications and mortality. Results: Patients with ScRVI in AIMIhad more admission hyperglycaemia (268.80 ± 81.88 mg/dl vs. 219.80 ± 98.40 mg/dl, P value =0.003), less incidence of complete ST elevation resolution (STR) (60.8 %vs. 80.6%, p value = 0.032), more arrhythmic complications (3 rd heart block [HB]: 6.7% vs. 0.0%, p value = 0.042, atrial fibrillation [AF]: 10.0% vs. 2.0%, p value = 0.036). Conclusions: We concluded that patients with ScRVI in AIMI had worse in hospital outcome than patients without ScRVI.
