The hallmark of COPD is chronic inflammation that affects central and peripheral airways, lung parenchyma and alveoli, and pulmonary vasculature. COPD is characterized by the restriction of airflow into and out of the lungs. Exacerbation of chronic obstructive pulmonary disease (COPD) is defined as an event in the natural course of the disease that is characterized by a change in the patient's baseline dyspnea, cough, or sputum beyond day-to-day variability and sufficient to warrant a change in management (1, 2).Recent studies have indicated that the state of health of patients with COPD … 0000216034 00000 n People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other con… 0000188847 00000 n There is a close relationship between the amount of tobacco smoked and the rate of decline in forced expiratory flow in one second (FEV1), although individuals vary greatly in susceptibility (Fletcher 1977). A key question in the pathogenesis of COPD is why so many people with significant exposure to known causes are spared the disease. COPD in non-smokers is more common in those with asthma and in older individuals. Cumulative, chronic exposure to cigarette smoking is the number one cause of the disease, but repeated exposure to secondhand smoke, air pollution, and occupational exposure (to coal, cotton, grain) are also important risk factors. 0000003744 00000 n 0000002699 00000 n Studies clearly show an increase in macrophage-predominant inflammation in the alveolar spaces and terminal bronchioles of current smokers.
