Evaluation of right ventricular systolic function in patients with acute myocardial infarction with ST-segment elevation undergoing pharmaco-invasive strategy or primary angioplasty.

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.
