Impairment of Ventilatory Efficiency in Heart Failure
Background—Impairment of ventilatory efficiency in congestive heart failure (CHF) correlates well with symptomatology and contributes importantly to dyspnea. Methods and Results—We investigated 142 CHF patients (mean NYHA class, 2.6; mean maximum oxygen consumption [V̇O2max], 15.3 mL O2 z kg 21 z min; mean left ventricular ejection fraction [LVEF], 27%). Patients were compared with 101 healthy c...
متن کاملObstructive? Restrictive? Or a ventilatory impairment?
Since 1991, the guidelines for interpretation of lung function tests endorsed by the American Thoracic Society (ATS) have recommended that the presence of airflow obstruction be determined by a reduction in the ratio of FEV1 to FVC (or vital capacity), but that the severity of the obstructive impairment be indicated by the reduction in FEV1 itself, expressed as a percent of its predicted value ...
متن کاملVentilatory impairment from pre-harvest retted flax.
A new method of retting flax recently developed to suit the United Kingdom climate has allowed the reintroduction of flax growing to this country. The weed killer glyphosate is sprayed on the crop which then rets before harvesting six weeks later. The acute bronchoconstrictor responses of 11 normal subjects to dust from dew retted and from pre-harvest retted flaxes were compared in a double bli...
متن کاملVentilatory Impairment In Petrol Pump Workers
Lung function tests have been of increasing interest in the use for qualitative and quantitative evaluation of pulmonary function in patients with abnormalities of cardiorespiratory system (1). Petroleum refining products are constituted by cycloalkanes, straight and branched chain alkenes which are continued source of pollution in various occupational settings (2). With the increasing use of p...
متن کاملImpairment of ventilatory efficiency in heart failure.
Heart Failure To the Editor: In these days of high-technology cellular biology, it is always a great pleasure to read research relating to whole-body integrated physiology. Kleber and colleagues1 are to be congratulated on presenting important data relating to the survival of real patients with exercise impairment. There are a number of important issues that I would draw attention to. The patie...
