Sleep disordered breathing in patients with cardiovascular comorbidities hospitalized for pulmonary disease

2015

Sleep disordered breathing (SDB) is often overlooked in hospitalized patients. We screened consecutive patients with cardiovascular (CV) comorbidities hospitalized for respiratory problems to study SDB prevalence and type. Patients did not refer typical clinical signs of SDB. Patients (n=34, 21 M, mean age±SD 71±12 yr, BMI: 31.9±5.8 kg/m2) were studied by polygraphy (SomnoLab, Weinmann, Germany) 4.5±3.2 days after admission for COPD exacerbation (COPD-E, n=20), pleural effusion (n=2), asthma exacerbation (n=2) or other causes (n=10). On admission, 18 patients showed respiratory failure (RF, hypoxemic: n=9, hypercapnic: n=9). CV comorbidities (1.7±0.8/patient) were: hypertension (n= 27), hea…
