AbstractObjectivesTo evaluate left atrial (LA) function using speckle tracking based strain (SPTS) in systolic heart failure (SHF) patients.BackgroundLA changes occur in patients with SHF and LA enlargement is commonly found by echocardiography. New speckle tracking based strain can be used to detect left atrial changes in SHF.Materials and methodsForty patients with clinical (SHF), EF<40%, NYHA class II-IV and normal sinus rhythm were compared with twenty-five age and sex matched healthy controls. Conventional echo was done where the LV dimensions, volumes, EF, wall thickness & LA diameter were measured. LA total emptying, passive and active volumes & fractions were calculated in both apical 4 & 2 chamber views. Peak atrial longitudinal st...
