The purpose of this study was to survey patients with heart failure (HF) for sleep symptoms using a standardized questionnaire and correlate symptoms with conventional markers of clinical status. A self-report paper questionnaire was offered to patients presenting to a tertiary care HF clinic. Symptoms were grouped according to "risk" categories and correlated with routine clinical information. One hundred six (52.7% of 201 with all data) respondents had a high pretest probability for sleep apnea syndrome. Sixty three (31.3%) reported symptoms suggesting the presence of chronic insomnia; seven (3.5%) and eight (4%) reported symptoms of narcolepsy and restless legs syndrome, respectively. High-risk respondents for sleep apnea had a higher body mass index (p<0.001), were younger (p<0.05), and had a higher ejection fraction (p<0.05). The odds ratio (confidence interval) for paroxysmal nocturnal dyspnea (PND) to a complaint of sleepiness was 1.99 (1.1-3.6) and to a complaint of insomnia was 3.5 (1.8-6.5). In men, complaints of sleepiness in patients with PND were correlated, 4.47 (1.9-10.3), as was a correlation to high pretest probability for sleep apnea, 2.47 (1.1-5.5). There were no correlation of New York Heart Association status classification to high risk for sleep apnea, but a complaint of insomnia tended to occur with worsening functional status (p<0.05). There was only modest correlation of self-reported symptoms as elicited by a questionnaire and risk for sleep disorders with common clinical assessments for HF. Such collection of symptoms might be useful in establishing guidelines for routine sleep testing or as an adjunct to clinical trials.

Restless legs syndrome (RLS) is a sensorimotor disorder characterized by distressing sensations deep inside the limbs, typically occurring at bedtime or rest. These paresthesias involve an irresistible urge to move the limb, which provides temporary relief but at the expense of sleep and quality of life. The pathophysiology of RLS has been related to dopaminergic pathway dysfunction, thereby aligning it closely with depression from both pathophysiologic and treatment perspectives. Certain antidepressant drugs, including the selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), may induce or exacerbate RLS. We describe the case of a 34-year-old woman with no history of RLS who came to the emergency department with acute decompensated heart failure. After 7 days of hospitalization, she was waitlisted to receive a heart transplant. Her mood became depressed, and she requested a psychiatric consultation; escitalopram 10 mg at bedtime was started. Within 2 days of starting therapy, she developed very severe (determined by a score based on an RLS symptom rating scale) RLS symptoms, warranting the discontinuation of escitalopram. Within 2 days of stopping therapy, her RLS symptoms improved considerably (rated as mild). One week later, the patient was rechallenged with a lower dose of escitalopram, and her very severe RLS symptoms reappeared. Within 2 days of stopping escitalopram, her RLS symptoms again improved, with complete resolution 1 week later. Using the Naranjo adverse drug reaction probability scale, which assesses the probability of a drug causing an adverse event, the patient's score was 9, indicating a definite adverse drug reaction. Although published case reports have linked fluoxetine, sertraline, citalopram, paroxetine, and mirtazapine to RLS, this is the first report, to our knowledge, of escitalopram as a cause of RLS. Based on this case and additional data published with other SSRIs and SNRIs, we believe that escitalopram should be added to the list of agents that can induce RLS.

Chronic congestive heart failure is a highly prevalent and progressive disorder associated with excess morbidity and mortality; it has huge economic impact. Left heart failure may be systolic or may occur as isolated diastolic dysfunction. The diastolic form predominates in older people. Sleep disorders are frequent in both types. Most systematic studies have been performed in patients with systolic heart failure. Prospective studies show the presence of obstructive and central sleep apnea, periodic limb movements, and significant alterations in sleep architecture, characterized by poor efficiency, excess stage 1 and arousals, and lack of deep sleep. Both obstructive sleep apnea and central sleep apnea occur in patients with heart failure and have been shown to be associated with excess mortality. Obstructive sleep apnea is best treated with continuous positive airway pressure (CPAP) devices. Central sleep apnea is also best treated with CPAP, but only about 50% of the patients are considered responders. Survival improves when heart failure patients are effectively treated with CPAP for both central and obstructive sleep apnea. A new positive airway pressure device, a pressure support servo-ventilator, is the next best choice for heart failure patients whose central sleep apnea does not respond to CPAP. Nocturnal oxygen should be used for patients whose central sleep apnea does not respond to positive pressure devices. Both periodic limb movements and insomnia could have adverse hemodynamic consequences for the failing heart. There are no guidelines or long-term studies regarding treatment of these conditions in heart failure. For restless legs syndrome with or without periodic limb movements, pramipexole and ropinirole have been approved. Treatment of insomnia comorbid with heart failure depends on the cause. In the absence of any known cause, a trial of ramelteon is the first choice.

Iron deficiency anemia still remains problematic worldwide. Iron deficiency without anemia is often undiagnosed. We reviewed, in this study, symptoms and syndromes associated with iron deficiency with or without anemia: fatigue, cognitive functions, restless legs syndrome, hair loss, and chronic heart failure. Iron is absorbed through the digestive tract. Hepcidin and ferroportin are the main proteins of iron regulation. Pathogenic micro-organisms or intestinal dysbiosis are suspected to influence iron absorption.

The restless legs syndrome (RLS) is a neurological disorder characterized by an irresistible urge to move the legs or arms for relief of uncomfortable or unpleasant sensations. Prevalence and prognostic impact of RLS on patients with heart failure (HF) remain unclear. We aimed to investigate the clinical characteristics and prognostic impact of RLS on HF patients.Consecutive 338 HF patients were evaluated for RLS and divided into two groups on the basis of presence of RLS: HF patients with RLS (RLS group, n = 29) and HF patients without RLS (non-RLS group, n = 309). We compared clinical characteristics, parameters of laboratory data and echocardiography, and rate of follow-up cardiac events including worsening HF and cardiac death between the two groups. Compared with the non-RLS group, the RLS group had higher prevalence of anemia (65.5% versus 40.8%, P = 0.010), higher usage of inotropic agents (31.0% versus 15.2%, P = 0.028), higher levels of B-type natriuretic peptide (570.8 versus 215.8 pg/mL, P = 0.018), and lower levels of left ventricular ejection fraction (40.4% versus 48.4%, P = 0.019). By contrast, age, gender, prevalence of other co-morbidities and medications were comparable between the groups. In the Kaplan-Meier analysis, the cardiac event rate was significantly higher in the RLS group than in the non-RLS group (log-rank P = 0.034). In the Cox proportional hazard analysis, RLS was a predictor for cardiac events in HF patients (hazard ratio: 1.783, 95% confidence interval: 1.038-3.063).RLS is associated with adverse prognosis in HF patients.

Burden symptom in advanced heart failure highly affects quality of life of both patients and caregivers, leading to severe functional limitation and social isolation. Symptoms in the advanced phases of the disease are numerous and often underestimated and undertreated. This negatively affects not only quality of life, but also increases hospitalizations, reduces therapeutic adherence, impairs cardiac function and leads to reduced survival. When symptom control cannot be achieved only with specific cardiologic therapy, optimal care should shift to a combination of life-prolonging and symptom-relief approach, possibly to be initiated as soon as advanced phases are detected. Optimal treatment of severe and invalidating symptoms requires a multi-modal and multi-dimensional approach, as pharmacological therapy represents only a part of a global evaluation that should include spiritual and psycho-social factors, potentially influencing symptom perception. Assessment therefore should rely on multi-modal and multi-dimensional patient-centered score models, such as the Edmonton Symptom Assessment System (ESAS), the Kansas City Cardiomyopathy Questionnaire (KCCQ), or the Integrated Palliative care Outcome Scale (IPOS).Pain, dyspnea, depression, fatigue and less frequent but distressing symptoms, including gastrointestinal disorders (nausea, vomiting, fecal impaction, hiccups), cough, itching, skin xerosis and restless legs syndrome, will be analyzed, and evidence of best palliative practice will be discussed.
