Prevalence and Characteristics of Anergia (Lack of Energy) in Patients With Acute Coronary Syndrome
Anergia, a commonly occurring syndrome in older adults and patients with cardiovascular diseases, is associated with functional and clinical limitations. To date, the prevalence and clinical–demographic characteristics of anergia in patients with acute coronary syndrome (ACS) have not been elucidated. We examined the prevalence and clinical–demographic characteristics of anergia in a multiethnic sample of patients with ACS. Hospitalized patients with ACS (n = 472), enrolled in the Prescription Usage, Lifestyle, and Stress Evaluation (PULSE) prospective cohort study, completed assessments of demographic, behavioral, and clinical characteristics within 7 days of hospitalization for an ACS event. Current depressive disorder was ascertained using a structured psychiatric interview 3 to 7 days after discharge. Anergia was assessed at baseline and defined using patients' binary responses (yes/no) to 7 items related to energy level. At least 1 complaint of anergia was reported by 79.9% of patients (n = 377) and 32% of patients (n = 153) met criteria for anergia. In a multivariable logistic regression model, anergia was independently associated with being a woman, being white (compared to black), having bodily pain, participating in exercise, having current depressive disorder, and having higher values on the Charlson Co-morbidity Index. In conclusion, anergia is a highly prevalent syndrome in patients with ACS. It is distinct from depression and is associated with modifiable clinical factors such as participation in exercise and bodily pain that may be appropriate targets for intervention.
