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

ABSTRACT: Background and Objectives: 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. Materials and Methods: COPD patients (n = 114) were evaluated using spirometry and transthoracic echocardiography. Statistical analysis utilized Student's t-test, chi-square test, and multivariable logistic regression with 1000 bootstrapping iterations, considering p < 0.05 as significant differences. Results: Most patients were classified as Global Initiative for Chronic Obstructive Lung Disease
