Left atrial strain (LASr) was an independent predictor of short-term major adverse cardiovascular events in patients with acute coronary syndrome (P=0.03), superior to left atrial volume index.

Does left atrial strain predict short-term major adverse cardiovascular events in patients with acute coronary syndrome?
Left atrial strain (LASr) is an independent predictor of short-term MACE in patients with ACS and may offer superior prognostic value compared to left atrial volume index.
p-value: p=0.03
Objectives: To explore the association between left atrial (LA) strain and the GRACE score in patients with acute coronary syndrome (ACS) and to investigate the utility of LA function in predicting short-term adverse cardiovascular events post ACS. Methods: This retrospective study included ACS patients who underwent coronary angiography (CAG) in two independent cohorts from October 2020 to July 2022. The patients were classified into low-intermediate risk group and high-risk group based on the GRACE score. All participants underwent a transthoracic echocardiogram, with LA strain analysis before CAG. Correlation analysis was used to determine the relationship between LA strain and the GRACE score. The predictive value of LA strain was examined utilizing the area under the curve (AUC). Participants were followed for 10.5 ± 2.9 months for the primary endpoint of major adverse cardiovascular events (MACE). Results: = 0.03) was the independent echocardiographic predictor for the primary endpoint, rather than left atrial volume index (LAVI). Conclusions: LASr can identify high-risk patients with ACS as defined by the GRACE score and may be superior to Max LAVI in predicting incidents of MACE in the short-term following ACS.
Li et al. (Wed,) conducted a cohort in Acute coronary syndrome (ACS). Left atrial strain (LASr) vs. Left atrial volume index (LAVI) was evaluated on Major adverse cardiovascular events (MACE) (p=0.03). Left atrial strain (LASr) was an independent predictor of short-term major adverse cardiovascular events in patients with acute coronary syndrome (P=0.03), superior to left atrial volume index.
