Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder with significant cardiovascular implications. A normal cardiac silhouette on imaging is often reassuring; however, it does not necessarily exclude underlying cardiac dysfunction. COPD is frequently associated with cardiac dysfunction, including right ventricular failure and pulmonary hypertension, due to chronic hypoxia and increased pulmonary vascular resistance. The cardiac silhouette on chest imaging plays a crucial role in assessing cardiac involvement, as changes in its size and shape can indicate right heart strain, cardiomegaly, or other cardiovascular complications. Early recognition of these abnormalities is essential for optimizing management and improving patient outcomes. Understanding the interplay between COPD and cardiac dysfunction through imaging can aid in timely intervention and reduce morbidity and mortality. A nontubular cardiac silhouette, characterized by an abnormal contour or enlargement, may indicate right heart dysfunction, cor pulmonale, or other structural cardiac changes. Recognizing these alterations is essential for early diagnosis and intervention, as cardiac involvement significantly impacts the prognosis of patients with COPD. Given the high prevalence of cardiovascular diseases among COPD patients, it is essential to evaluate the role of cardiac silhouette assessment in predicting cardiac dysfunction. Accurate assessment through imaging can guide appropriate management strategies, improving patient outcomes.
