Objective: To measure the point prevalence of delirium in the patients admitted to the cardiac ICU with acute coronary syndromes, with particular attention to the most commonly noted delirium and the impact on ICU mortality and length of ICU stay. Study Design: Prospective cohort study. Place and Study Duration: National Institute of Cardiovascular Diseases, Karachi Pakistan, from Mar and Jul 2021. Methodology: Consecutive adult patients with age >18 years admitted to the cardiac ICU after acute coronary syndromes were assessed for delirium using the confusion assessment method (CAM)-ICU tool and Richmond agitation sedation score (>-3). The types of delirium were also assessed. Results: 201 patients were enrolled, half of patients with ST-elevation MI (51.2%) and shock (45.8%). Delirium was identified in 71 (35.3%) patients, 30 (42.2%) had hypoactive delirium and 41 (57.7%) had hyperactive delirium. In multivariable regression, independent risk factors for delirium were: sepsis 3.19 (1.15-8.87), uremia 4.12 (1.18-14.46), mechanical ventilation 7.58 (1.2-47.99), and non-invasive ventilation 8.55 (2.9-25.2). Overall mortality was 35 (17.4%); 27/71 (38%) vs. 8/130 (6.2%); p 0.001 in patients with and without delirium, respectively. In multivariable regression, delirium was an independent risk factor for mortality at 7.12 (2.16-2.23). The mean ICU stay was 7.772.36 days vs. 3.91.44 days; p 0.001 for patients with and without delirium. Conclusion: The deleterious effect of delirium in terms of higher morbidity and mortality cannot be overemphasised. Hypoactive delirium is as common as the hyperactive type, with the same mortality risk. Assessment for delirium is mandatory for all patients admitted..............
