Objective: To assess differences in right ventricular function between the primary angioplasty and pharmacoinvasive groups using echocardiographic parameters. Method: Observational, retrospective, and cross-sectional study conducted on 111 patients in a cardiac care unit, where ventricular function was evaluated through transthoracic echocardiography. Results: There were no significant differences in right ventricular function parameters (TAPSE, FAC, S’ wave, RV Tei index, right V/A coupling) between both groups. As a notable finding, the pharmacoinvasive group exhibited better LVEF and smaller volumes at the end of diastole and systole. Conclusions: In patients with STEMI undergoing the pharmacoinvasive strategy compared to those receiving primary angioplasty, there is no significant difference in the main right ventricular function parameters assessed by transthoracic echocardiography.
