RESUMO

BACKGROUND: In COPD, impaired left ventricular (LV) filling might be associated with coexisting HFpEF or due to reduced pulmonary venous return indicated by small LV size. We investigate the all-cause mortality associated with small LV or HFpEF and clinical features discriminating between both patterns of impaired LV filling. METHODS: We performed transthoracic echocardiography (TTE) in patients with stable COPD from the COSYCONET cohort to define small LV as LVEDD below the normal range and HFpEF features according to recommendations of the European Society of Cardiology. We assessed the E/A and E/e' ratios, NT-pro-BNP, hs-Troponin I, FEV1, RV, DLCo, and discriminated patients with small LV from those with HFpEF features or no relevant cardiac dysfunction as per TTE (normalTTE). The primary outcome was all-cause mortality after four and a half year. RESULTS: In 1752 patients with COPD, the frequency of small LV, HFpEF-features, and normalTTE was 8%, 16%, and 45%, respectively. Patients with small LV or HFpEF features had higher all-cause mortality rates than patients with normalTTE, HR: 2.75 (95% CI: [1.54 - 4.89]) and 2.16 (95% CI: [1.30 - 3.61]), respectively. Small LV remained an independent predictor of all-cause mortality after adjusting for confounders including exacerbation frequency and measures of RV, DLCo, or FEV1. Compared to normalTTE, patients with small LV had reduced LV filling, as indicated by lowered E/A. Yet in contrast to patients with HFpEF-features, patients with small LV had normal LV filling pressure (E/e') and lower levels of NT-pro-BNP and hs-Troponin I. CONCLUSION: In COPD, both small LV and HFpEF-features are associated with increased all-cause mortality and represent two distinct patterns of impaired LV filling This article is open access and distributed under the terms of the Creative Commons Attribution Non-Commercial No Derivatives License 4.0 (http://creativecommons.org/licenses/by-nc-nd/4.0/).

RESUMO

BACKGROUND: Interdisciplinary medical treatment is required to care for patients with complex autoimmune diseases. Although there are an increasing number of interdisciplinary centers for autoimmune diseases in Germany, they are not yet available throughout the country and the focuses and interdisciplinary structures are not organized according to a generally agreed standard. Furthermore, they are not regularly reflected in the general care structure. THE AIM OF THE WORK: To analyze the care structure using as an example an established center and a clinical case to demonstrate the usefulness of in-house standardized procedures. MATERIAL AND METHODS: In order to determine the status quo regarding interdisciplinary centers for autoimmune diseases in Germany, a university hospital is exemplarily presented for a structural analysis and a case presentation from another center to demonstrate the importance of an interdisciplinary patient care. RESULTS: At the selected center for autoimmune diseases of the university hospital, patients with autoimmune diseases receive interdisciplinary care from experts from various disciplines. The structures are anchored in an organizational chart. The case report demonstrates a standardized diagnostic and therapeutic pathway (standardized operating procedures, SOP) in a patient with systemic sclerosis and lung involvement. DISCUSSION: The article discusses which measures are necessary across disciplines for comprehensive diagnostics and treatment of certain autoimmune diseases, which challenges arise during implementation and which advantages can arise compared to guidelines because, among other things, they can be immediately adapted. The establishment of a national consensus for the structure, necessary settings and implementation into patient care within an interdisciplinary center for autoimmune diseases is desirable.
