Restrictive lung diseases are a diverse set of pulmonary disorders defined by restrictive patterns on spirometry; these restrictive lung patterns as shown on a spirometer are the revelation of a dysfunction in the respiratory ability of the lung(s) which is caused by restrictive lung disease. Restri...
Although airflow obstruction on spirometry has been demonstrated to be an independent risk factor for osteoporosis, incident coronary artery disease and heart failure, overall cardiovascular mortality, and lung cancer, the consequences of a spi-rometric restriction are not as clear. In this issue of...
Infection would be considered in the differential though the pattern on spirometry can vary so it will not be discussed here– for example if the infection is chronic bronchitis it can have an obstructive pattern, if it is more distal it can have a restrictive pattern or mixed features. So ...
16 Although some of the above studies assessed the relation of lung function to morbidity and mortality prospectively, they used a single spiro- metric test at enrolment to measure lung function. Low FVC values assessed by spirometry can also be found in a proportion of normal subjects who ...
Moreover, obstructive pulmonary disease can be diagnosed through medical history, physical examination, spirometry, peak expiratory flow (PEF) test, fractional exhaled nitric oxide test (FeNO) test, arterial blood gas test, CT scan, and chest X-ray. Furthermore, treatment options for obstructive...
Methods and Materials We retrospectively evaluated 193 lung transplant recipients (LTR) transplanted between 2001-2009 in a single center, identifying individuals whose CLAD showed a restrictive pattern on spirometry. Histological phenotypes were defined. Risk factors for BOS were compared in those with ...
Neither measure is particularly accurate in characterizing severity, and neither measure is superior to the other.CLINICAL IMPLICATIONS: Spirometry must be used with caution when grading the severity of restrictive pulmonary disease.DISCLOSURE: The following authors have nothing to disclose: Sean Roark, ...
However, the performance of spirometry to detect restrictive lung diseases is generally poor and especially so if the prevalence of the disease in the tested population is low such as in many working populations. Our aim was to increase the specificity and the positive predictive value (PPV) of...
The term cardiac dyspnoea was used if dyspnoea arose 'from arrest in the passage of blood through the heart to the lungs'.1 Early studies using spirometry observed that patients with heart disease had lower vital capacity than 'normal individuals'.2 Many years later, prospective analyses of ...
restrictive spirometry patternBACKGROUND\nSpirometry-based studies of occupational lung disease have mostly focused on obstructive or mixed obstructive/restrictive outcomes. We wanted to determine if restrictive spirometry pattern (RSP) is associated with occupation and increased mortality.METHODS\nStudy ...
