Echocardiographic Evidence of Left Ventricular Dysfunction in COPD: Relationship with Disease Severity.

: Chronic obstructive pulmonary disease (COPD) significantly impacts morbidity and mortality, often due to cardiovascular comorbidities that are frequently overlooked. This study examines the prevalence of left ventricular dysfunction in COPD patients and its association with disease severity, hypoxemia, and exacerbation frequency. : COPD patients ( = 114) were evaluated using spirometry and transthoracic echocardiography.
