Prognostic value of left atrial reservoir strain for major adverse cardiovascular events in coronary artery disease
A systematic review and meta-analysis of 17 studies and 9,404 patients with coronary artery disease found that, in acute coronary syndrome, each 1% higher left atrial reservoir strain was associated with lower major adverse cardiovascular-event risk (pooled adjusted HR 0.94, 95% CI 0.92–0.95; I²=27%). This supports prognostic-marker potential but does not yet show added value over standard models or improved treatment outcomes.
