Chronic Obstructive Pulmonary Disease Phenotypes: Implications for Care

Area of Science:

• Pulmonology
• Clinical Medicine
• Respiratory Medicine

Background:

• Chronic obstructive pulmonary disease (COPD) is a heterogeneous condition.
• Effective management requires understanding patient subgroups.
• Phenotyping offers a framework for personalized care.

Purpose of the Study:

• To review clinically meaningful COPD phenotypes.
• To identify phenotypes with distinct management and prognostic implications.
• To highlight phenotypes recognizable by primary care physicians and specialists.

Main Methods:

• Literature review of COPD phenotyping studies.
• Synthesis of existing research on COPD phenotypes.
• Identification of seven key phenotypes based on clinical relevance.

Main Results:

• Seven clinically meaningful COPD phenotypes are described.
• These include asthma-COPD overlap, frequent exacerbator, and upper lobe-predominant emphysema.
• Other phenotypes are rapid decliner, comorbid, physical frailty, and emotional frailty.

Conclusions:

• COPD phenotyping provides valuable clinical insights.
• These phenotypes guide tailored treatment strategies.
• Recognizing these phenotypes improves patient outcomes and prognosis.
