Why the study?
It was unknown whether left atrial strain assessed by echocardiography provides prognostic information in patients with wild-type transthyretin amyloid cardiomyopathy.
Does left atrial strain during the reservoir phase predict cardiovascular death in patients with wild-type transthyretin amyloid cardiomyopathy?
Population
113 patients with ATTRwt-CM and adequate two-dimensional speckle tracking echocardiography
Comparison
Cardiovascular death group vs non-event group
Design
Single-center observational cohort study
Follow-up
Median 668 days

May support risk stratification in ATTRwt-CM; leaves open incremental value beyond biomarkers in prospective studies.
