Clinical InvestigationDepressive Symptoms Affect the Relationship of N-Terminal Pro B-Type Natriuretic Peptide to Cardiac Event-Free Survival in Patients With Heart Failure
Section snippets
Design and Procedure
This was a prospective study of patients with HF recruited from outpatient HF clinics between January 1, 2004, and December 31, 2007. Patients were recruited from 1 regional tertiary medical center and several community hospitals located in Lexington, KY. Approval from the Institutional Review Board at each of the hospitals was obtained before the study. Written informed consent was obtained from patients. At baseline, all patients visited the General Clinical Research Center to have blood
Sample Characteristics
Sample characteristics are displayed in Table 1. The majority of the patients were older than 60 years old with an age range of 24 to 87 years. As a group, patients were primarily in NYHA functional Class II/III. Nearly two thirds had ischemic heart disease as the underlying etiology of HF. Almost one third of the patients had preserved systolic function with LVEF >40%. The common comorbidities were hypertension and diabetes mellitus. The mean value of NT-pro BNP was 733 pg/mL, whereas the
Discussion
This is the first study to demonstrate that the prognostic relationship of NT-pro BNP to cardiac event-free survival of patients with HF differed by the presence of depressive symptoms after controlling for age, gender, etiology of HF, BMI, NYHA functional class, LVEF, total comorbidity score, and the interaction between level of NT-pro BNP and the presence of depressive symptoms. The most compelling finding of this study was the relationship of NT-pro BNP and cardiac event-free survival among
Conclusions
Coexistence of elevated NT-pro BNT and severe depressive symptoms predicted shorter cardiac event-free survival in patients with HF. NT-pro BNP was a nonsignificant predictor of cardiac event-free survival in the absence of depressive symptoms. Depressive symptoms were a strong predictor of cardiac event-free survival as well as more widely used biological marker such as NT-pro BNP. Monitoring and treatment of depressive symptoms are important for improving cardiac event-free survival in

Depression in heart failure: Can PHQ-9 help?
2016, International Journal of CardiologyCitation Excerpt :PHQ-9 contains 9 items, each corresponding to a diagnostic criterion from the Diagnostic and Statistical Manual of Mental Disorders (DSM IV), and it diagnoses major depression with a sensitivity and specificity of 88% [17–20]. Despite its clinical utility in other populations, PHQ-9 has only recently begun to be utilized in research studies to evaluate depression in HF [21–25]. Furthermore, associations between PHQ-9 scores and measures of healthcare utilization, cardiovascular endpoints, and patient-centered outcomes remain under-studied in stable HF outpatients.
Health Literacy Predicts Morbidity and Mortality in Rural Patients with Heart Failure
2015, Journal of Cardiac FailureCitation Excerpt :Both clinically diagnosed depression and depressive symptoms are linked, independently, to morbidity and mortality.41–44 We have previously demonstrated that depressive symptoms are an even stronger predictor for poor outcomes among patients with heart failure than B-type natriuretic peptide levels.45 The independent association of both health literacy and depression with poor outcomes highlights the importance of cognitive and psychologic variables in the clinical management of heart failure.
The Association of Co-morbid Symptoms of Depression and Anxiety With All-Cause Mortality and Cardiac Rehospitalization in Patients With Heart Failure
2015, PsychosomaticsCitation Excerpt :The Patient Health Questionnaire (PHQ-9) was used to measure depressive symptoms in this study.29,30 The PHQ-9 is a 9-item, self-reported measure of depression that reflects the severity of depressive symptoms over the past 2 weeks.31,32 Patients respond to each item using a Likert scale in which responses range from 0 (not at all) to 3 (nearly every day).
Antidepressants do not improve event-free survival in patients with heart failure when depressive symptoms remain
2013, Heart and Lung: Journal of Acute and Critical CareCitation Excerpt :Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9), a valid and reliable instrument for the measurement of depressive symptoms.24,25 The PHQ-9 has been used to predict quality of life and mortality in HF.23,26 The PHQ-9 has 9 items that reflect the criteria for diagnosis of clinical depression from the Diagnostic and Statistical Manual-IV.
