Incidence and outcomes of diabetes mellitus amongst hospital admissions with

Background: Diabetes Mellitus (DM) is a recognized risk factor for the development of acute and chronic heart failure (HF). Methods: This retrospective cohort study was conducted at the largest advanced HF center in Qatar. All patients admitted with DNHF were grouped as: 1) newly diagnosed DM, 2) pre-existing DM, 3) prediabetes, and 4) no DM. Clinical characteristics and in-hospital/post-discharge outcomes were described. Continuous variables were reported as mean with standard deviation or IQR and categorical variables as frequency distribution with percentage. Results: Among 260 patients with DNHF, 173 (66.5%) had DM, and 52 (20%) were prediabetic. Newly diagnosed DM was identified in 26 (10%), 147 (56.5%) were known diabetics. Compared with known DM, newly diagnosed patients were predominantly male (92.3% Conclusion: Our findings indicate the high burden of dysglycemia (DM and prediabetes) that is present in DNHF patients. Furthermore, DNHF served as the initial clinical presentation of DM or prediabetes in approximately one-third of our patients. This underscores the need for routine metabolic screening in patients presenting with DNHF, as early identification and management of DM is crucial in this population to improve outcomes.
