BACKGROUND Pulmonary hypertension (PH) restricts the ability to engage in physical activity and decreases longevity. We examined the impact of aerobic exercise training on function and quality of life in patients with World Health Organization group 1 PH. METHODS Patients were randomized to a 10-week education only (EDU) or education/exercise combined(More)
RATIONALE The relationship between pulmonary artery size with underlying pulmonary hypertension and mortality remains to be determined in COPD. We sought to evaluate the relationships in a cohort of patients with advanced COPD. METHODS A retrospective study of advanced COPD patients evaluated between 1998 and 2012 was conducted at a tertiary care center.(More)
BACKGROUND The course of idiopathic pulmonary fibrosis (IPF) is characterized by variable patterns of disease progression. The red cell distribution width (RDW) is a parameter that is routinely reported with all CBC counts. We sought to test the prognostic usefulness of this parameter in a well-defined cohort of patients with IPF. METHODS CBCs,(More)
The American Thoracic Society and European Respiratory Society guidelines for the diagnosis and treatment of idiopathic pulmonary fibrosis (IPF) have been published recently. However, the influence, practical application, and utility of the prior consensus statement for IPF have never been evaluated. Demographics, diagnostic criteria, pulmonary function(More)
UNLABELLED IPF patients have heightened propensity for pulmonary hypertension, which portends a worse outcome. Presence of pulmonary hypertension may be reflected in an enlarged pulmonary artery. We investigated pulmonary artery size measured on high-resolution computed tomography (HRCT) as an outcome predictor in IPF.We retrospectively reviewed all IPF(More)
PURPOSE To characterize the cardiorespiratory response to exercise before and after aerobic exercise training in patients with interstitial lung disease. METHODS We performed a clinical study, examining 13 patients (New York Heart Association/World Health Organization Functional class II or III) before and after 10 weeks of supervised treadmill exercise(More)
BACKGROUND The goal of the 6-min walk test (6MWT) is to enable patients to walk "as far as possible" as a measure of their functional ability. The impact of the specific walk instructions on patient 6MWT performance is unknown. METHODS Patients with pulmonary arterial hypertension (PAH), idiopathic pulmonary fibrosis (IPF), and other forms of interstitial(More)
RATIONALE Although lipids, apolipoproteins, and lipoprotein particles are important modulators of inflammation, varying relationships exist between these parameters and asthma. OBJECTIVES To determine whether serum lipids and apolipoproteins correlate with the severity of airflow obstruction in subjects with atopy and asthma. METHODS Serum samples were(More)
OBJECTIVE The outcomes of patients with idiopathic pulmonary fibrosis (IPF) who undergo hospitalization have not been well characterized. We sought to determine the frequency of all-cause and respiratory-related hospitalizations and to evaluate their impact on the subsequent course and survival of patients with IPF. METHODS The records of patients with(More)
BACKGROUND AND OBJECTIVE Patients with idiopathic pulmonary fibrosis (IPF) have a higher prevalence of coronary artery disease and this could have an impact on their outcomes. We investigated the predictive ability of coronary artery calcification, assessed by routine CT, which may predict the presence of coronary artery disease. METHODS The study cohort(More)
