Right ventricular function and determining factors of dysfunction in ST-segment-elevation myocardial infarction: a cross-sectional study with cardiac magnetic resonance imaging (MRI).

RV dysfunction was detected in 32.28% of STEMI patients. Patients with acute STEMI and RVEF <50% had impaired LV and IVS functions. Systolic function of the LV and IVS, peak troponin, and culprit lesions in the RCA were independent predictors of RV dysfunction in STEMI patients.
