OBJECTIVES The goal of this study was to determine the prevalence of depression in an out-patient heart failure (HF) population; its relationship to quality of life (QOL); and the impact of gender, race, and age. BACKGROUND Most studies of depression in HF have evaluated hospitalized patients (a small percentage of the population) and have ignored the(More)
Background—Nesiritide (synthetic human brain natriuretic peptide) is approved for the treatment of symptomatic heart failure. However, studies of brain natriuretic peptide in patients with heart failure have come to conflicting conclusions about effects on glomerular filtration rate (GFR), effective renal plasma flow, natriuresis, and diuresis. Methods and(More)
BACKGROUND Depression is frequently observed in patients with heart failure and is associated with poor quality of life and adverse prognosis. However, the prevalence of depression in heart failure could be overestimated because symptoms of depression overlap with those of heart failure. Similarly, the importance of depression may be overestimated if(More)
OBJECTIVES This study was designed to evaluate the consequences of ultrafiltration (UF) and standard intravenous diuretic (furosemide) therapy on glomerular filtration rate (GFR) and renal plasma flow in patients with acute decompensated heart failure. BACKGROUND It has been hypothesized that treatment with diuretics may worsen renal function as the(More)
The purpose of this study was to evaluate the test-retest reliability of intraventricular dyssynchrony (IVD) assessment by tissue Doppler imaging (TDI) echocardiography. Limited response rates to cardiac resynchronization may improve with TDI screening for appropriate recipients. However, the clinical applicability of TDI will depend on the reliability of(More)
OBJECTIVES This study was conducted to evaluate whether brain (B-type) natriuretic peptide (BNP) changes during sleep are associated with the frequency and severity of apneic/hypopneic episodes, intermittent arousals, and hypoxia. BACKGROUND Sleep apnea is strongly associated with heart failure (HF) and could conceivably worsen HF through increased(More)
AIM Cerebrovascular disease (CVD) has been associated with depression and a host of neuropsychiatric conditions including dementia. This study assessed the relationship between cerebrovascular findings reported on MRI brain scans and neuropsychiatric symptoms (NPS) and behavioural problems in patients with Alzheimer's disease (AD).
