Key result
Systolic heart failure was associated with significantly reduced left atrial function, including lower peak atrial longitudinal and contraction strain, compared to healthy controls.
Why the study?
Does speckle tracking based strain detect left atrial function changes in patients with systolic heart failure compared to healthy controls?
Population
65 individuals: 40 patients with clinical systolic heart failure and 25 age- and sex-matched healthy controls.
Comparison
Speckle tracking based strain echocardiography vs Healthy controls
Design
Case-control

May support speckle tracking for LA assessment in systolic HF; leaves open prognostic or therapeutic utility.

Does speckle tracking based strain detect left atrial function changes in patients with systolic heart failure compared to healthy controls?
Speckle tracking echocardiography demonstrates that left atrial reservoir and booster pump functions are significantly reduced in systolic heart failure and correlate with disease severity.
Ahmed et al. (2014) conducted a case-control in Systolic heart failure (n=65). Systolic heart failure vs. Healthy controls was evaluated on Left atrial function parameters including peak atrial longitudinal strain (PALS) and peak atrial contraction strain (PACS). Systolic heart failure was associated with significantly reduced left atrial function, including lower peak atrial longitudinal and contraction strain, compared to healthy controls.
