Relationship Between Left Atrial Volume and Strain Parameters and Prognosis of Acute Anterior Myocardial Infarction
Objective To analyze the relationship between left atrial volume,deformation parameters and prognosis in patients with acute anterior myocardial infarction ( AAMI ) .Methods 105 AAMI patients who underwent PCI at our hospital from 2022 to 2023 were included.Their clinical data,including left atrial volume ( LAVmax,LAVmin,LAVpre ) and deformation parameters ( LASr,LAScd,LASct ),were collected.A three-month follow-up was conducted.The patients were divided into the good prognosis group and the poor prognosis group according to the occurrence of major adverse cardiovascular events ( MACE ) .The factors affecting MACE were investigated by multivariate logistic regression analysis.Results In this study,37 patients had MACE,with an incidence rate of 35.24％.The proportion of patients with age>65 years,hypertension history,and the levels of LAVmin,LAVmax,and LAVpre were significantly higher in the poor prognosis group,while the levels of LASr,LAScd,and LASct were significantly lower ( P<0.05 ) .Age>65 years,hypertension history,enlarged left atrial volume,and lower levels of left atrial deformation parameters were independent risk factors for postoperative MACE in AAMI patients ( P<0.05 ) .Conclusion Enlar ged left atrial volume and lower levels of left atrial deformation parameters could increase the risk of postoperative MACE in AAMI patients and were related to their prognosis.
