COPD is responsible for considerable morbidity and mortality, and its course is complicated by co-existing comorbidities that worsen prognosis. Understanding the importance of comorbidity and multiple comorbidities in COPD is important in patient assessment and management planning. This Monograph is the first comprehensive collection of up-to-date articles on COPD comorbidity. It includes chapters on epidemiology, cardiovascular disease, diabetes, psychological disease and infection, and covers the importance of including comorbidity in COPD treatment guidelines, as well as the ways in which comorbidity influences clinical COPD management. This book will be of interest to clinicians, healthcare professionals, and those researching this important area.
