| Summary: | The prevalence and fatality rate of asthma have increased worldwide. Underdiagnosis and undertreatment of asthma are central to the occurrence of fatal asthma. Atopy is the principal risk factor associated with asthma. However, consideration of the epidemiologic, physiologic, pharmacologic, pathologic and clinical parameters of asthma assessment may provide valuable insight into death due to asthma. Psychologic and socioeconomic factors may further aggravate the asthma status. Ethnic minorities are at increased risk of asthma. The perception of dyspnea may be blunted in asthma sufferers. Slow-onset fatal asthma may be associated with submucosal eosinophilic, whereas sudden-onset may be associated with submucosal neutrophilia. Fatal asthma occurs in patients abusing regular |32-agonist therapy. Peak flow assessment often provides insight into asthma deterioration prior to signs of respiratory distress. Markers of risk of death due to asthma further identify the fatality-prone asthma patient.
