Dyspnea and a Lung Opacity on Radiography - Photo Quiz
ABSTRACT: Pulmonary rehabilitation is a nonpharmacologic therapy that has emerged as a standard of care for patients with chronic obstructive pulmonary disease. It is a comprehensive, multidisciplinary, patient-centered intervention that includes patient assessment, exercise training, self-management education, and psychosocial support. In the United States, pulmonary rehabilitation is usually given in outpatient, hospital-based programs lasting six to 12 weeks. Positive outcomes from pulmonary rehabilitation include increased exercise tolerance, reduced dyspnea and anxiety, increased self-efficacy, and improvement in health-related quality of life. Hospital admissions after exacerbations of chronic obstructive pulmonary disease are also reduced with this intervention. The positive outcomes associated with pulmonary rehabilitation are realized without demonstrable improvements in lung function. This paradox is explained by the fact that pulmonary rehabilitation identifies and treats the systemic effects of the disease. This intervention should be considered in patients who remain symptomatic or have decreased functional status despite optimal medical management. Medicare now covers up to 36 sessions of pulmonary rehabilitation in patients with moderate, severe, and very severe chronic obstructive pulmonary disease.
Diagnostic Evaluation of Dyspnea - Article
ABSTRACT: Dyspnea is a common symptom and, in most cases, can be effectively managed in the office by the family physician. The differential diagnosis is composed of four general categories: cardiac, pulmonary, mixed cardiac or pulmonary, and noncardiac or nonpulmonary. Most cases of dyspnea are due to cardiac or pulmonary disease, which is readily identified with a careful history and physical examination. Chest radiographs, electrocardiograph and screening spirometry are easily performed diagnostic tests that can provide valuable information. In selected cases where the test results are inconclusive or require clarification, complete pulmonary function testing, arterial blood gas measurement, echocardiography and standard exercise treadmill testing or complete cardiopulmonary exercise testing may be useful. A consultation with a pulmonologist or cardiologist may be helpful to guide the selection and interpretation of second-line testing.

Causes and Evaluation of Chronic Dyspnea - Article
ABSTRACT: Chronic dyspnea is shortness of breath that lasts more than one month. The perception of dyspnea varies based on behavioral and physiologic responses. Dyspnea that is greater than expected with the degree of exertion is a symptom of disease. Most cases of dyspnea result from asthma, heart failure and myocardial ischemia, chronic obstructive pulmonary disease, interstitial lung disease, pneumonia, or psychogenic disorders. The etiology of dyspnea is multifactorial in about one-third of patients. The clinical presentation alone is adequate to make a diagnosis in 66 percent of patients with dyspnea. Patients’ descriptions of the sensation of dyspnea may be helpful, but associated symptoms and risk factors, such as smoking, chemical exposures, and medication use, should also be considered. Examination findings (e.g., jugular venous distention, decreased breath sounds or wheezing, pleural rub, clubbing) may be helpful in making the diagnosis. Initial testing in patients with chronic dyspnea includes chest radiography, electrocardiography, spirometry, complete blood count, and basic metabolic panel. Measurement of brain natriuretic peptide levels may help exclude heart failure, and D-dimer testing may help rule out pulmonary emboli. Pulmonary function studies can be used to identify emphysema and interstitial lung diseases. Computed tomography of the chest is the most appropriate imaging study for diagnosing suspected pulmonary causes of chronic dyspnea. To diagnose pulmonary arterial hypertension or certain interstitial lung diseases, right heart catheterization or bronchoscopy may be needed.
