Abstract

This study was aimed at searching new instruments for primary differentiation of dyspnea associated with lung or heart pathology. The study consisted of 3 stages and included analysis of "glossary dyspnea" of 482 patients aged 18-90yr. Stages i and II involved 359 patients with the known diagnosis: chronic obstructive pulmonary disease (COPD) (n=114, 31.8%), bronchial asthma (BA) (n=134, 3 7.3%), chronic heart failure (CHF) unrelated to lung pathology (n=111, 30.9%). The patients were 205 (57.1%) men and 154 (42.9%) women. Stage III involved 123 patients complaining ofdyspneapresumably ofpulmnonary or cardiac origin. 75 (61.0%) of these patients were men, 48 (39.0%) women aged 18-89 yr. Subsequent comprehensive diagnostics revealed BA in 47 (38.2%), COPD in 46 (37.4%), CHF in 30 (24.4%) patents. Stage I was designed to evaluate the dyspnea language based on the frequency of the phases of glossary dyspnea (Simon et al., 1999) and Fisher's Z criterion. It permitted to create the modified glossary dyspnea (MGD) consisting of 11i phrases and 7 clusters that revealed statistically significant differences between patients with BA, COPD, and CHE At stage II, we developed the model for estimating the probability of a priori diagnosis (...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
