Article type: Original Article Introduction: Left ventricular ejection fraction (LVEF) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. LVEF is not improved in all patients after coronary artery bypass grafting (CABG). This study aimed to assess the possibility of prediction of LVEF changes after CABG using myocardial perfusion gat...
AIMS Lupus myocarditis occurs in 5-10% of patients with systemic lupus erythematosus (SLE). No single feature is diagnostic of lupus myocarditis. Speckle tracking echocardiography (STE) can detect subclinical left ventricular dysfunction in SLE patients, with limited research on its utility in clinical lupus myocarditis. We report on STE in comparison to conventional echocardiography in patient...
BACKGROUND Whether patients with reduced left ventricular function present worse outcome after transcatheter aortic valve implantation (TAVI) is controversial. The aim of this study was to assess the impact of baseline severe impairment of left ventricular ejection fraction (LVEF) on mortality after TAVI. METHODS Six-hundred-forty-nine patients with aortic stenosis underwent TAVI with the Cor...
Introduction: Although left ventricular(LV) function parameters measured by gated myocardial perfusion SPECT (GSPECT) have been validated, experimental data have revealed that the calculated the LV function parameters using GSPECT are affected by patient populations as well as particular acquisition and processing conditions. We tried to determine the normal values ...
Results baseline LVEF was similar (p = 0.2) between ACE e BB groups, 61.9 ± 5% and 58,3 ± 7% respectively. DUAL group had a lower mean LVEF of 54 ± 11%. At follow up, LVEF was unchanged in ACE group ( from 61.9 to 61.2%), and improved in BB group, from 58 to 63% (p = 0,04). In DUAL group LVEF improved in a similar extent from 54 to 59% (p 0,01). Myocardial T2 STIR edema, significantly decreased...
BACKGROUND Silent brain infarcts (SBIs) and white matter hyperintensities are subclinical cerebrovascular lesions associated with incident stroke and cognitive decline. Left ventricular ejection fraction (LVEF) is a predictor of stroke in patients with heart failure, but its association with subclinical brain disease in the general population is unknown. Left ventricular global longitudinal str...
BACKGROUND Patients with severe aortic stenosis and reduced left ventricular ejection fraction (LVEF) have a poor prognosis with conservative therapy but a high operative mortality when treated surgically. Recently, transcatheter aortic valve implantation (TAVI) has emerged as an alternative to surgical aortic valve replacement (SAVR) for patients considered at high or prohibitive operative ris...
BACKGROUND A negative electrophysiology study (EPS) may delineate a subgroup of patients with severely impaired left ventricular ejection fraction (LVEF) whose care can be safely managed long-term without an implantable cardioverter-defibrillator. METHODS AND RESULTS Consecutive patients treated with primary percutaneous coronary intervention for ST-segment-elevation myocardial infarction und...
BACKGROUND As the number of angina patients with severe coronary artery disease not amenable to revascularization increases, new therapies will be developed. How patients with depressed compared to normal left ventricular ejection fraction (LVEF) will respond to new therapies may differ. HYPOTHESIS We conducted a retrospective chart review to determine the distribution of LVEF in angina patie...
