The effects of urgent percutaneous coronary intervention on right ventricular systolic functions in non-ST-elevation acute coronary syndromes

Abstract

Abstract:Background: Although the importance of the right ventricle (RV) involvement has been known for many years in patients with ST-elevation myocardial infarction (STEMI), it is scarce in non-ST-elevation acute coronary syndrome (NSTE-ACS). Objectives: We aimed to investigate the eff ects of urgent percutaneous coronary intervention (PCI) on the RV systolic functions in patients with NSTE-ACS. Materials and Methods: Ninety-fi ve patients diagnosed with NSTE-ACS and who underwent urgent PCI were prospectively investigated. RV systolic functions were analyzed and compared before and after PCI in all patients by using RV index of myocardial performance (RIMP), tricuspid annular plane systolic excursion (TAPSE), two-dimensional (2D) RV fractional area change (FAC), and isovolumic acceleration (IVA) parameters with transthoracic echocardiography. Results: Among 95 NSTE-ACS patients, 31 had impaired RIMP, 13 had impaired TAPSE, 8 had decreased 2D FAC, and 32 had impaired IVA values at baseline. There was a signifi cant increase in 2D FAC and IVA values after PCI. Conclusions: The right ventricular functions may also be aff ected in patients with NSTE-ACS, and urgent PCI has a signifi cant eff ect on the recovery of right ventricular systolic functions in patients with NSTE-ACS.

Correlation between Right Ventricular Function with Revascularization Time and 30-day Mortality in ST-Elevation Myocardial Infarction Patients Underwent Right Coronary Artery Intervention

“…One study in patients with right ventricular dysfunction after NSTE-ACS found that TAPSE and RIMP value of these patients were not significantly different before and after a succesful PCI. 21 This maybe associated with myocardial stunning after an acute myocardial infarction. RV dysfunction is reversible in most patients and permanent RV ischemic injury is very uncommon four months after acute MI treated with primary PCI.…”
