Effect of obesity on B-type natriuretic peptide levels in patients with pulmonary arterial hypertension.

Brain natriuretic peptide (BNP) levels are lower in obese patients with left ventricular failure than in their comparably ill, leaner counterparts. The effect of obesity on BNP in patients with pulmonary arterial hypertension (PAH) is unknown. We reviewed our prospective PAH registry data collected from November 2001 to December 2007 for patients undergoing right heart catheterization who met the criteria for PAH and had the BNP level and body mass index determined at baseline.

Comparison of baseline predictors of prognosis in pulmonary arterial hypertension in patients surviving ≤2 years and those surviving ≥5 years after baseline right-sided cardiac catheterization.

Idiopathic pulmonary arterial hypertension (PAH) is usually associated with a poor outcome but the prognosis with other forms of PAH is not well-described. Advances in therapy have furthered clouded the disease course. We sought to determine the baseline indicators of prognosis in patients with PAH.

Sleep quality, depression, and quality of life in patients with pulmonary hypertension.

Pulmonary hypertension is a disabling disease characterized by progressive functional worsening, right heart failure, and death. Although pulmonary hypertension has been associated with poor quality of life, sleep quality has not been investigated in pulmonary hypertension patients. This was a cross-sectional study in which patients (N = 40) were asked to complete standardized questionnaires to assess sleep quality [using Pittsburgh Sleep Quality Index (PSQI)], insomnia, sleepiness, dyspnea, depression, restless leg syndrome, and quality of life [using Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR)] during routine office visits.

Ocular complications in patients with lung transplants.

Aim: To describe infectious and non-infectious ocular complications found in patients with lung transplants.

Methods: 545 patients underwent lung transplantation from January 1998 to September 2008 at the Cleveland Clinic. Patients who underwent ophthalmic examination at the Cole Eye Institute after lung transplantation were included in the study.
