Abstract

Right ventricle (RV) dysfunction in patients with ST elevation myocardial infarction (STEMI) is more common and important than previously considered. The aim of this study was to determine the incidence of RV involvement in acute STEMI by using advanced echocardiography (Echo) methods, such as RV longitudinal strain and three-dimensional (3D) ejection fraction, and to prove that RV involvement is not exclusive to right coronary artery damage in STEMI. The study group was formed of 73 patients aged 30 to 60 years with confirmed first-time acute STEMI and coronary angiography performed. Abnormality thresholds for standard and advanced Echo parameters in case of STEMI for predicted RV dysfunction were RV 3D ejection fraction < 49% and RV free wall longitudinal strain > –24.5 %. Using these abnormality thresholds it was possible to detect RV dysfunction in 60% of STEMI cases. The acquired results are close to the cardiac magnetic resonance data found in literature, which is the gold standard for determination of RV systolic function. RV involvement did not depend on the damaged coronary artery, as there was no association detected (p = 0.09); therefore, RV function should be assessed in every STEMI patient, and Echo is an effective method for this purpose.
