Influence of Left Ventricular Hypertrophy on In-Hospital Outcomes in Acute Exacerbation of Chronic Obstructive Pulmonary Disease

<p>Left ventricular hypertrophy (LVH) is associated with worse outcomes in chronic obstructive pulmonary disease (COPD); however, its role in an acute exacerbation of COPD (AECOPD) has not been reported. This was a retrospective cohort study during 2008–2012 at an academic medical center. AECOPD patients >18 years with available echocardiographic data were included. LVH was defined as LV mass index (LVMI) >95 g/m² (women) and >115g/m² (men). Relative wall thickness was used to classify LVH as concentric (>0.42) or eccentric (<0.42). Outcomes included need for and duration of non-invasive ventilation (NIV) and mechanical ventilation (MV), NIV failure, intensive care unit (ICU) and total length of stay (LOS), and in-hospital mortality. Two-tailed p < 0.05 was considered statistically significant. Of 802 patients with AECOPD, 615 patients with 264 (42.9%) having LVH were included. The LVH cohort had higher LVMI (141.1 ± 39.4 g/m² vs. 79.7 ± 19.1 g/m²; p < 0.001) and lower LV ejection fraction (44.5±21.9% vs. 50.0±21.6%; p ≤ 0.001). The LVH cohort had statistically non-significant longer ICU LOS, and higher NIV and MV use and duration. Of the 264 LVH patients, concentric LVH (198; 75.0%) was predictive of greater NIV use [82 (41.4%) vs. 16 (24.2%), p = 0.01] and duration (1.0 ± 1.9 vs. 0.6 ± 1.4 days, p = 0.01) compared to eccentric LVH. Concentric LVH remained independently associated with NIV use and duration. In-hospital outcomes in patients with AECOPD were comparable in patients with and without LVH. Patients with concentric LVH had higher NIV need and duration in comparison to eccentric LVH.</p
