Relation of global longitudinal strain to left ventricular geometry in aortic valve stenosis.
BACKGROUND In patients with aortic stenosis (AS), increased afterload induces changes in left ventricular (LV) geometry to preserve a normal ejection fraction (EF). Nevertheless, myocardial dysfunction may occur in spite of a normal EF. Global longitudinal strain (GLS) analysis can detect subtle contractile dysfunction at a pre-clinical stage. The aim of our study was to assess LV function dete...
متن کاملRelation between Voice Handicap Index (VHI) and disease severity in Iranian patients with Parkinson’s disease
Background: One third of patients with Parkinson’s disease (PD) have mentioned “dysphonia” as their most debilitating communication deficit. Patient-based measurements, such as Voice Handicap Index (VHI) add necessary supplementary information to clinical and physiological assessment. There are a few studies about relation between VHI and disease severity in PD, although none of them showed an...

Relation of microvascular dysfunction to exercise capacity and symptoms in patients with severe aortic stenosis
Background The management of asymptomatic patients with severe AS remains controversial and clinical practice varies. Echocardiographic measures of severity do not discriminate between symptomatic status or predict exercise capacity. The purpose of this study was to investigate the mechanisms contributing to symptom generation and exercise intolerance. This needs to be fully understood to optim...
متن کاملGlobal strain in severe aortic valve stenosis: relation to clinical outcome after aortic valve replacement.
BACKGROUND Global longitudinal systolic strain (GLS) is often reduced in aortic stenosis despite normal ejection fraction. The importance of reduced preoperative GLS on long-term outcome after aortic valve replacement is unknown. METHODS AND RESULTS A total of 125 patients with severe aortic stenosis and ejection fraction >40% scheduled for aortic valve replacement were evaluated preoperative...
