Abstract: Right ventricular
(RV) involvement increases mortality and morbidity in inferior myocardial
infarction (MI). There are sparse data on the usefulness of pulsed tissue
Doppler imaging (TDI) in the diagnosis of RV dysfunction in ST segment
elevation MI (STEMI). This study evaluate the diagnostic and prognostic
significance of RV systolic and diastolic function compared to classical
electrocardiographic RVMI diagnostic criteria in this group of patients. Consecutive
patients with first, acute, inferior STEMI were prospectively assessed. The
RVMI was defined as an ST-segment elevation ≥ 0.1 mV in lead V4R.
Echocardiography with TDI was performed within 24 h of the onset of symptoms.
Out of 31 patients (mean age 56.39 ± 9.02 years), RVMI was found in 18 (37%).
Multivariate analysis showed that two variables—RV systolic and diastolic
function, were independent predictors of in-hospital prognosis. Sensitivity and
specificity the RV systolic function were 94,4% and 69,2%, respectively. While
RV diastolic function were 44% and 76,9%, respectively. RV systolic function
predict ECG diagnosis of RVMI with relatively high sensitivity and specificity.
RV diastolic function predict ECG diagnosis of RVMI with relatively low sensitivity
but with high specificity.
