Materials and Methods: This retrospective study at a tertiary heart center (March 2017-December 2022) included octogenarian patients (≥80 years) hospitalized for acute coronary syndrome (ACS)heart failure (HF)or cardiac arrhythmias. Patients were categorized into CICU (n=512) and GMW (n=548) groupswith analysis of clinicaldemographicand outcomes data. Results: Mean ages were similar between CICU and GMW groups (84.8±6.8 vs. 85.0±5.8 years; p=0.440). In-hospital mortality was higher in the CICU group (18.0% vs. 10.0%p<0.001)as were complications like sepsis (10.5% vs. 6.9%p=0.024)acute kidney injury (15.8% vs. 10.2%p=0.008)and delirium (32.0% vs. 17.5%p<0.001). Logistic regression showed STEMI (OR=2.80p<0.001)intubation (OR=3.50p<0.001)acute kidney injury (OR=2.10p<0.001)sepsis (OR=2.30p<0.001)and delirium (OR=1.50p=0.002) as significant predictors of mortality. Conclussion: CICU admissionwhile critical for high-risk octogenariansespecially those with STEMIcorrelates with increased mortality and complications. Effective patient selection and preventive measures are vital to improve outcomes in this vulnerable group.eninfo:eu-repo/semantics/openAccessGeriatri Ve GerontolojiYoğun BakımTıpKalp Ve Kalp Damar SistemiArticle3921791841400476
