Abstract
Abstract Aims Tricuspid annular plane systolic excursion (TAPSE) is one of the most established echocardiographic parameters to assess global function of the right ventricle (RV). This study sought to evaluate TAPSE to predict early outcomes and ascertain whether its value adds beneficial prognostic information to patients with myocardial infarction. Methods and Results Of all 899 patients who were diagnosed with ST-segment elevated myocardial infarction (STEMI) between July 2018 to June 2019, 576 patients underwent echocardiography examination within 24-hour of onset. The subjects were categorized into two groups: TAPSE ≤18 mm (n = 265) and TAPSE >18 mm (n = 311). Primary outcomes were the incidence of cardiogenic shock, cardiac arrest, and in-hospital mortality. A total of 576 patients (513 males, mean age 55±10) with STEMI diagnosis who underwent percutaneous coronary intervention were enrolled to this study. In the overall cohort, TAPSE ≤18 mm was statistically associated with greater incidence of cardiogenic shock (p = 0.001), cardiac arrest (p = 0.002), and in-hospital mortality (p = 0.001). Multivariate analysis showed that TAPSE ≤18 mm was an independent predictor of cardiogenic shock (OR, 2.951; 95% CI, 1.507 to 5.781), cardiac arrest (OR, 2.500; 95% CI, 1.381 to 4.527), and in-hospital mortality (OR, 2.868; 95% CI, 1.460 to 5.632). Conclusion The assessment of TAPSE that represents RV function among STEMI patients can be considered as a prognostic factor regarding early outcomes. Long-term follow-up is necessary to obtain more comprehensive prognostic information.
