Influence on prognosis and prevalence of stress hyperglycemia in a cohort of patients with acute coronary syndrome.

Objective: To demonstrate the prevalence of stress hyperglycemia in a cohort of patients with acute coronary syndrome and to determine the correlation of stress hyperglycemia with death, heart failure and/or left ventricular systolic dysfunction during the intrahospital phase.

Methods: A prospective initial cohort study of hospitalized patients with acute coronary syndrome with or without ST segment elevation. The groups were compared to demonstrate the correlation between stress hyperglycemia and cardiovascular events.

Prevalence and variables predictive of depressive symptoms in patients hospitalized for heart failure.

Background: Our study set out to determine the prevalence of depressive symptoms and variables that influence its presence in patients hospitalized for heart failure. Depression is associated with a substantially increased risk of developing heart failure in individuals at risk, and has been related to adverse outcomes in patients with established heart failure. It is important to determine its prevalence in different populations and assess related causes.
