Aims:
Despite improvement in prognosis for ST-elevation myocardial infarction (STEMI) patients, mortality remains high in STEMI patients presenting with cardiogenic shock (CS). Right ventricular (RV) dysfunction is an established independent predictor for adverse prognosis in STEMI patients without CS. The purpose of our study was to determine the prognostic value of RV dysfunction on admission in STEMI patients presenting in CS.
Methods And Results:
Two hundred and ninety-two consecutive STEMI patients with CS on admission were treated by primary percutaneous coronary intervention (PCI) from January 1997 through March 2005. RV function was assessed by measurement of tricuspid annular plane systolic excursion (TAPSE) on early echocardiography in 184 of 292 patients. Right ventricular dysfunction was defined as a TAPSE of
Conclusion:
In STEMI patients presenting with CS on admission and treated with primary PCI, RV dysfunction as assessed by echocardiography is an independent predictor for long-term mortality.
