Brain natriuretic peptide (BNP) is a cardiac neurohormone secreted by myocardium in response to ventricular wall tension.3 In patients with dyspnea, plasma N-terminal pro-BNP concentrations are increased in left ventricular dilatation, hypertrophy, systolic dysfunction, or diastolic dysfunction, but not by pulmonary dysfunction.21 BNP and N-terminal pro-BNP levels can be used to distinguish between heart failure and pulmonary causes of dyspnea.26,27, d-dimer is a marker of fibrin degradation. COPD, or chronic obstructive pulmonary disease, is a serious lung disease that over time makes it hard to breathe.

This book comprehensively addresses the use of pulmonary function measurement for the evaluation, screening and timing of noninvasive mechanical ventilation (NIMV) from hospital to home care. Patients may have advanced airflow limitation but only mild dyspnea.11, Standard inventories to determine the association between level of activity and dyspnea are available.2 A five-item scale that assesses age, wheezing, dyspnea, smoking, and cough may be helpful in identifying patients who should be assessed with spirometry (Figure 1).12 Using a cutoff value of 18 or less, the negative predictive value of the questionnaire is 92.3 percent, with an 82.6 percent sensitivity for the diagnosis of COPD.12, Enlarge 2 In systolic HF patients, dyspnea is thought to arise from pulmonary congestion as left ventricular dysfunction causes cardiac output to decrease . The absence of aggravation of dyspnea by exercise should prompt consideration of functional causes.7.
