Exercise performance of polycythemic chronic obstructive pulmonary disease patients. Effect of phlebotomies.
The purpose of this study was to determine the effects of phlebotomy on the exercise tolerance and right and left ventricular ejection fraction of polycythemic patients with chronic obstructive pulmonary disease. Ten patients with COPD (mean FEV1 = 1.32 +/- 0.55 L) and polycythemia (mean Hct = 62 +/- 3 percent) were studied before and after their hematocrits had been reduced to approximately 50...
متن کاملThe Role of EDD (Exercise Capacity, Dyspnea, and Diffusing Capacity of Lungs for Carbon Monoxide) Index in Pulmonary Fibrosis Secondary to Scleroderma
Introduction: Pulmonary involvement secondary to Systemic Sclerosis (SSc) is the major cause of morbidity and mortality in SSc patients. We designed this study to determine the correlation of important lung function parameters with lung High Resolution CT (HRCT) scan findings. Materials and Methods: Thirty–two consecutive diffuse SSc patients with pulmonary fibrosis were enrolled in this cross...
متن کاملPulmonary Rehabilitation in Idiopathic Pulmonary Fibrosis: A Chance for a Multidisciplinary Treatment Approach
Background and Objectives: Idiopathic pulmonary fibrosis (IPF) is characterized by progressively worsening lung function, ventilation capacity, dyspnea, and finally reduced exercise intolerance. All of these have a significant negative impact on functional capacity and quality of life. In this study, we aim to evaluate the effects of pulmonary rehabilitation (PR) in IPF and assess the predictor...
متن کاملThe Circulatory and Ventilatory Effects of Normovolemic Polycythemia †
The effects of primary and secondary polycythemia on circulatory and ventilatory events have been the center of much investigation. There has, however, been sharp disagreement about the clinical merit of phlebotomy in cases of secondary polycythemia. Howarth, et al.' and Lewis, et al.,' among others, have concluded, although for somewhat different reasons, that therapeutic phlebotomy is detrime...
متن کاملThe erythropoietin-hematocrit relationship in normal and polycythemic man: implications of marrow regulation.
(juirements.’ Changes in need are met in part by changes in the circulating red cell mass. Accordingly, erythropoietin has been demonstrated in the urine and plasma of patients with anemia or polycythemia of varying origin. However, investigations relating erythropoietin to erythropoiesis in normal mdividuals have only recently been made possible by improved assay methods. This study was undert...
