Assessing the Use of Left Atrial Strain Before and After Treadmill Exercise Stress Echocardiography.

ABSTRACT:

Aims

Left atrial strain (LAS) is a novel speckle-tracking technique used in the assessment of left atrial function. It has been shown to be a marker for adverse cardiac events (heart failure, myocardial ischemia, and atrial fibrillation). This study aimed to assess the role of LAS in assessing risk for diastolic dysfunction and myocardial ischemia in stress echocardiography (SE) before and after treadmill exercise.

Methods and results

Patients undergoing routine Bruce protocol SE had LAS measurements (reservoir, conduit, and contractile strain) assessed before and after maximal treadmill exertion. Changes in LAS were measured and compared based on the result of the SE. Consecutive SE (n = 420) were analyzed (mean age 62 ± 5 years, 37% female). LAS was able to be estimated be
