Left Atrial Strain for Predicting MACE in NSTEMI
Incremental Prognostic Value of Left Atrial Reservoir Strain Beyond the GRACE 2.0 Score and Conventional Echocardiographic Parameters for Predicting 6-Month MACE in Patients With NSTEMI

Detaljert beskrivelse
Non-ST-elevation myocardial infarction (NSTEMI) carries significant short- and long-term risk of major adverse cardiovascular events despite advances in management. Current risk stratification relies on clinical scores such as GRACE 2.0 and conventional echocardiographic parameters including left ventricular ejection fraction (LVEF) and left atrial volume index (LAVI). These tools have limitations, as LVEF may remain preserved and LAVI mainly reflects chronic remodeling.
Left atrial (LA) reservoir strain assessed by two-dimensional speckle tracking echocardiography is a sensitive marker of left ventricular filling pressure and diastolic function. Reduced LA reservoir strain has been associated with adverse outcomes after NSTEMI, but data on its incremental prognostic value beyond established risk models remain limited.
This prospective observational study will assess whether LA reservoir strain independently predicts 6-month MACE and improves risk discrimination when added to the GRACE 2.0 score and conventional echocardiographic parameters in patients with NSTEMI.

Left atrial reservoir strain
Tidsramme: Baseline
|
Peak atrial longitudinal strain (PALS) during the reservoir phase measured by two-dimensional speckle tracking echocardiography (EchoPAC software), expressed as percentage (%).
Higher values indicate better left atrial function.
