Incidence, Predictors and Associations Between In-Hospital Bleeding and Adverse Events in Patients with Acute Coronary Syndrome Above 75 Years of Age

Announcing a new article publication for Cardiovascular Innovations and Applications journal. Bleeding events in patients with acute coronary syndrome (ACS) are associated with poor outcomes. Risk factors and their associations with in-hospital events in older patients with ACS are not fully understood, because older patients with ACS are often excluded from randomized controlled studies.

The authors of this article enrolled 962 patients with ACS above 75 years of age treated at a center between January 2012 and December 2016. The incidence and risk factors for in-hospital bleeding events, as well as their associations with in-hospital adverse events were evaluated.

Bleeding complications were observed in 38 patients (4.1%). The most common bleeding site was the gastrointestinal tract (52.6%). Anemia (P=0.007), renal insufficiency (P=0.019), use of positive inotropic medicines (P=0.006) and elevated leukocyte count (P=0.046) were independent predictors of in-hospital bleeding after adjustment for age, sex, atrial fibrillation history and hypertension history. In-hospital mortality (28.9% vs. 2.4%, P<0.001), stroke (5.3% vs. 0.5%, P<0.001) and the prevalence of heart failure (39.5% vs. 16.3%, P<0.001) were significantly higher in patients with than without bleeding.

The incidence of in-hospital bleeding was 4.1% in patients with ACS above 75 years of age in this cohort. Independent risk factors for in-hospital bleeding events included anemia, renal insufficiency and elevated leucocyte count. Bleeding events were strongly associated with in-hospital adverse events.
