Abstract

paraclinical characteristics, ACTION ICU score, and in-hospital events requiring intensive care unit (ICU) admission in patients aged 65 years and older with non-ST-elevation myocardial infarction (NSTEMI). Methods: A retrospective study was conducted on 122 patients aged ≥65 years who were hospitalized for NSTEMI at Gia Dinh People's Hospital from January 2022 to December 2023. Results: In-hospital events requiring ICU admission occurred in 18% of patients, with respiratory failure being the most common event (9.8%). Factors significantly associated with these events included: heart failure on admission (=0.001), history of chronic heart failure (p=0.036), ST-segment depression (p=0.029), reduced left ventricular function (p=0.042), lower systolic blood pressure (p=0.046), and chronic obstructive pulmonary disease (COPD) (p=0.01). Most events occurred within the first 24 hours of admission (86.4%). The average ACTION ICU score was 8.3 ± 3.7, and the score increased with the risk of in-hospital events. Conclusion: Among elderly patients with NSTEMI, 18% experienced in-hospital events requiring ICU admission. These events were associated with heart failure on admission, history of chronic heart failure, ST-segment depression, reduced left ventricular function, low systolic blood pressure, COPD, and higher ACTION ICU scores.
