Why the study?
Malnutrition is prevalent in Bangladesh but often overlooked in clinical care, and malnourished ACS patients may experience worse outcomes despite nutritional assessment rarely being routine.
Does malnutrition, as assessed by the CONUT scoring system, increase in-hospital mortality and duration of hospital stay in adult patients with acute coronary syndrome?
Does malnutrition, as assessed by the CONUT scoring system, increase in-hospital mortality and duration of hospital stay in adult patients with acute coronary syndrome?
Malnutrition assessed by the CONUT score is prevalent in acute coronary syndrome patients and serves as a significant independent predictor of increased in-hospital mortality and prolonged hospital length of stay.
Acute Coronary Syndrome (ACS) remains a leading cause of mortality in Bangladesh, where malnutrition is prevalent but often overlooked in clinical care. Malnourished ACS patients may experience worse outcomes, yet nutritional assessment is rarely routine. This study evaluates the impact of nutritional status on short-term outcomes using CONUT scoring. This prospective cohort study was conducted at the Department of Cardiology, Bangladesh Medical University, Dhaka, Bangladesh, over 18 months. A total of 100 adult ACS patients were included in the final analysis and stratified into nutritional status categories using the Controlling Nutritional Status (CONUT) scoring system. Key outcomes included in-hospital mortality and length of stay. Statistical analyses were performed using SPSS version 29.0.2.0, employing ANOVA, Fisher's exact test, and regression models to examine associations between nutritional status and clinical outcomes. Among the patients, 43% had mild malnutrition, 24% had moderate malnutrition, and 33% had no malnutrition. Nutritional status was significantly associated with both duration of hospital stay ( p < .001) and mortality ( p = .003). Patients with moderate malnutrition had significantly longer hospital stays (β = 4.388, p < .001) and higher mortality odds (β = 0.167, p < .001) compared to those without malnutrition. Nutritional status, particularly moderate malnutrition as assessed by CONUT scoring, is a significant predictor of adverse clinical outcomes in ACS patients. Integrating nutritional assessment in ACS management protocols may improve prognosis and reduce healthcare burdens. • Nutritional status was assessed using the CONUT scoring system in ACS patients. • Moderate malnutrition significantly increased hospital stay duration (β = 4.388). • Mortality was significantly higher in moderately malnourished patients (p = .003). • No patients were classified as severely malnourished in this cohort. • Routine nutritional screening could enhance ACS care outcomes in resource-limited settings.
