OBJECTIVE To assess the impact of Cheyne-Stoke respiration-central sleep apnea (CSR-CSA) on quality of life (QOL) in patients with congestive heart failure (CHF). QOL was established using the MLHFQ (Minnesota Living with Heart Failure Questionnaire), and the FOSQ (Functional Outcomes of Sleep Questionnaire). METHODS We examined 90 patients with CHF. The(More)
The present study assessed the usefulness of home cardiorespiratory polygraphy as an alternative to overnight polysomnography for the diagnosis of sleep-disordered breathing in heart failure. A total of 75 patients with chronic stable heart failure due to systolic dysfunction (left ventricular ejection fraction < or =45%) underwent polysomnography at the(More)
The objective of this study was to compare the frequency of some sociocultural, clinical, and anthropometric data between men and women in a sample of 1745 patients referred to a Sleep Unit for symptoms of obstructive sleep apnea (OSA). A standardized questionnaire was administered and anthropometric data were measured. Patients underwent a polysomnography(More)
OBJECTIVE To determine the utility and reliability of a respiratory polygraphy (RP) device with actigraphy (Apnoescreen II; Erich Jaeger GMBH & CoKg; Wuerzburg, Germany) in the diagnosis of sleep apnea-hypopnea syndrome (SAHS). DESIGN A prospective randomized study with blinded analysis. PATIENTS Sixty-two patients with suspected SAHS. MEASUREMENTS(More)
Chronic obstructive pulmonary disease (COPD) has traditionally been considered an inexorably progressive disease, associated with a constant increase of symptoms that occur as the forced expiratory volume in 1 second (FEV1) worsens, only intermittently interrupted by exacerbations. However, this paradigm has been challenged in recent decades by the(More)
STUDY OBJECTIVE To assess the possible relationship between Cheyne-Stokes respiration (CSR) associated with central sleep apnea (CSA) syndrome and brain natriuretic peptide (BNP) in an outpatient population presenting with stable congestive heart failure (CHF). MEASUREMENTS AND RESULTS Ninety patients with CHF due to systolic dysfunction (left ventricular(More)
Pulmonary exacerbation (PEx) is a hallmark of cystic fibrosis. Although several criteria have been proposed for the definition of PEx, no consensus has yet been reached. Very often, many PEx cases go unreported. A standardized and validated definition is needed to reduce variability in clinical practice. The pathophysiology of recurrent episodes remains(More)
This study was conducted to determine the influence of puberty on features of sleep-disordered breathing (SDB) in adolescents. The study was performed in a general population sample of 226 adolescents of both sexes (aged 11-19 yrs) recruited from the secondary school population of the city of Seville, Spain. Subjects were divided into two groups: 1)(More)
Few data are known about the effects of sleep-related breathing disorders (SRBD) on the cardiovascular system in adolescents. Forty healthy adolescents (mean age, 13.7 +/- 1.6 years) answered a questionnaire regarding symptoms of sleep-related breathing disorders (SRBD) and underwent a cardiorespiratory polygraphy and echocardiography. Echocardiographic(More)
OBJECTIVE To date, available mortality trends due to cystic fibrosis (CF) have been limited to the analysis of certain countries in different parts of the world showing that mortality trends have been constantly decreasing. However, no studies have examined Europe as a whole. The present study aims to analyze CF mortality trends by gender within the(More)
