Background: The prognostic significance of diabetes mellitus (DM) on hospitalization outcomes of patients with acute decompensated heart failure (ADHF) remains inconclusive.

Objectives: To comprehensively assess the clinical outcomes of patients with and without DM hospitalized for ADHF.

Methods: This single center retrospective cohort study included consecutive hospitalized patients with a principal diagnosis of ADHF between 1 January 2010 and 31 December 2019. Patients were categorized into diabetic and non-diabetic groups. The primary outcomes assessed were in-hospital mortality, 1-year overall mortality, and readmission rate within a year of follow-up.

Results: The final analysis involved 787 ADHF patients, with 62% having a pre-existing diagnosis of DM. Despite a higher burden of co-morbidities in diabetic patients, there were no differences in clinical outcomes when compared to non-diabetic counterparts. Specifically, there were no differences in overall hospital mortality (10% vs. 10%, P = 0.675), 1-year mortality (22% vs. 25%, P = 0.389), and re-admissions (51% vs. 56%, P = 0.154). Notably, the 1-year mortality among diabetic patients was not influenced by HbA1c levels documented before or during admission.

Conclusions: The clinical outcomes of patients hospitalized with ADHF did not differ by the presence of diabetes. Instead, our findings emphasize the importance of early heart failure prevention and subsequent hospitalization. Considering the evolving landscape of disease-modifying therapies for heart failure, achieving this goal becomes increasingly feasible.

Background: Anti-endothelial cell antibodies (AECA) are a known biomarker of endothelial dysfunction and damage in clinical practice, especially in autoimmune disease.

Objectives: To determine the relation between natural AECA levels and prognosis related to coronary artery disease.

Methods: Candidates for coronary angiography were prospectively enrolled. AECA levels were determined by ELISA assay. Mortality was evaluated after more than 5 years follow-up.

Results: Of a total 857 patients, 445 had high AECA levels (group 1) and 412 had low levels (< 1 OD unit, group 2). Both groups did not differ in age, sex, or presence of diabetes. The median follow up was 2293 days (76 months). Patients with high AECA levels were more likely to have normal coronary arteries on angiography (21.6% vs. 16.9%, P = 0.047) and less likely to have calcified lesions (19.0% vs. 26.6%, P = 0.028) and lower prevalence of abnormal renal functions (71.1 mg/dl vs. 66.5 mg/dl, P = 0.033). Patients with higher AECA levels had lower mortality levels (20.1% vs. 27.6%, P = 0.006). A logistic regression model demonstrated independent association between lower AECA levels and the presence of coronary atherosclerosis based on angiogram.

Conclusions: After a median of more than 6 years, higher natural AECA levels were associated with less coronary artery disease and lower mortality rates in patients undergoing coronary angiography
