“…the male patients in our study were younger than those in the literature. 5,26 Although the variable "time elapsed between symptom onset and hospital admission" cannot be considered to be a direct predictive factor regarding patient evolution, it has already been observed in a study conducted by Franken et al 27 , in our institution, that 30% of myocardial infarction cases, regardless of the affected ventricle, arrive at the hospital six hours after symptom onset.…”

INTRODUCTIONApproximately 50% of inferior wall infarction cases are associated with right ventricular (RV) infarction. 1,2 The incidence of left ventricular (LV) infarction in association with RV infarction ranges from 14% to 84%. [3][4][5] Infarction of the right ventricle alone, on the other hand, is reported in less than 3% of myocardium infarction (MI) cases. 6,7 From an epidemiological point of view, these differences make it diffi cult to accurately evaluate the impact of RV infarction in populations studied.It is the right coronary artery that is most frequently involved, obstructed in its proximal third, thus resulting in dysfunction of the free walls of the right ventricle and the walls of the inferior left ventricle. 8 Although the performance of the right ventricle spontaneously improves even in the absence of coronary reperfusion, its recovery may be slow and may be associated with high rates of atrioventricular conduction, hemodynamic instability and hospital mortality. 9-11 Reperfusion optimizes the recuperation of the right ventricle and improves patients' clinical evolution. 8 The gold standard for the diagnosing of RV infarction is hemodynamic evaluation or an autopsy. It is known that this diagnosis may be made by clinical evaluation, 12,13 electrocardiogram (EKG), hemodynamic evaluation, studies using radioisotopes such as technetium 99m ( 99m Tc) pyrophosphate, and right nuclear ventriculography.EKG using the right V 3 and V 4 (V 3 R and V 4 R) derivations is a simple method presenting good sensitivity and specifi city. 14-17 Identifi cation of right ventricular abnormality, shown by elevation of the ST segment in the right derivations, especially V 4 R, is an important predictor of hospital complications and mortality. 17 It is now known that thrombolytic therapy in patients presenting infarction in

“…Right ventricular (RV) dysfunction may be seen as a consequence of right ventricular myocardial infarction (MI) which is seen in about 50% of patients with inferior MI and 10% of patients with anterior MI [1,2]. Although RV involvement in acute MI usually does not attract enough attention during patient care, it may compromise hemodynamics and play an important prognostic role.…”

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.
