Study of the Features of Systolic Function of the Left Ventricle of Patients with Chronic Heart Failure in Combination with Chronic Obstructive Pulmonary Disease

The combination of chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) represents a frequent challenge in clinical practice due to shared risk factors such as smoking, environmental influences, and comorbidities. This study aimed to investigate the changes in systolic function of the left ventricle (LV) in patients with CHF, COPD, and their combination, focusing on clinical assessment and exercise tolerance. A total of 120 patients were divided into three groups: CHF (n=40), CHF + COPD (n=40), and COPD (n=40). Comprehensive echocardiographic evaluations and clinical assessments were conducted.Results revealed that while most LV systolic function parameters remained within normal ranges, significant deviations were observed in LV myocardial mass and hypertrophy, particularly in CHF and CHF + COPD groups. Patients with CHF demonstrated more pronounced abnormalities compared to those with isolated COPD. Moreover, COPD was associated with preserved LV systolic function in 100% of cases outside terminal CHF stages. Functional classification of patients by NYHA showed predominant moderate (II) and severe (III) physical activity limitations across all groups, with no significant differences.Key findings indicate a progression of LV dysfunction and myocardial remodeling severity in the series COPD –COPD + CHF –CHF. These results underscore the importance of echocardiographic evaluation in differentiating the impact of CHF and COPD on cardiac structure and function. Understanding these distinctions aids in tailoring management strategies for this complex patient population.
