Liver stiffness as measured by transient elastography is a predictor of outcomes in patients with chronic heart failure with reduced, mid-range, and recovered left-ventricular ejection fraction.

Background: Transient elastography is a noninvasive method for assessing liver stiffness (LS), which can reflect right-sided filling pressure associated with passive liver congestion in patients with HF. Methods: A prospective, single-center observational study in which LS was measured in consecutive ambulatory patients with heart failure with reduced, mid-range, and recovered left ventricular ejection fraction, between March 2018 and June 2019. Mean follow up was 219 ± 86 days. The primary endpoint was time to first event, which was defined as a composite of cardiovascular death or HF hospitalization. Results: Eighty-five patients were included in the final analysis. Mean age was 62 ± 10 and 68% were male. Mean ejection fraction and median NT-proBNP were, respectively, 38.7 ± 14.3% and 1140 pg/mL (interquartile range 224.3-2810.3). The median LS for the entire population was 6.3 (2.5-41.2) kPa. LS correlated with NT-proBNP (r = 0.46; p < 0.0001), total bilirubin (r = 0.47; p < 0.001), direct bilirubin (r = 0.43; p = 0.0001), gama-glutamyl-transpeptidase (r = 0.54; p < 0.0001), and alkaline phosphatase (r = 0.39; p = 0.0004). A Receiver Operating Characteristic (ROC) curve was performed and a cut point of 5.9 kPa showed sensitivity of 80% and specificity of 64.1% with area under the curve of 0.73. Using Cox proportional hazard model (independent variables: LS as a continuous variable, age, gender, NT-proBNP, LVEF, and creatinine), only LS was independently associated with the primary endpoint (hazard ratio 1.05, 95% confidence interval 1.01-1.09; for each increment of one unit of LS). Conclusion: LS correlates with biomarkers of myocardial stretch and several liver function tests and is an independent predictor of outcomes in ambulatory patients with HF.

Complete Atrioventricular Block and Cardiopulmonary Involvement in Rapidly Progressive Systemic Sclerosis

Abstract The heart and lung are target organs in systemic sclerosis (SSc) and similar symptoms (dyspnea and cough) may make the differential diagnosis between the two lesions difficult. In addition, complete atrioventricular block (CAVB) is a rare complication of this disease. This case report is about a patient with SSc and pulmonary fibrosis who was admitted to the emergency room with CAVB, heart failure (HF) and progressive worsening of the underlying disease.

Pulmonary Disease Secondary to Reflux Mimicking Interstitial Pneumonia in Systemic Sclerosis: Case Report and Literature Review.

Systemic sclerosis is a complex disease due to the variety of clinical presentations, often superimposed on other conditions, related or not to the connective tissue. We report a 43-year-old Brazilian woman with limited systemic sclerosis and pulmonary symptoms secondary to gastroesophageal reflux disease, with a clinical presentation similar to a diffuse interstitial lung disease. Because of the frequency of interstitial lung injury due to systemic sclerosis, this was an important differential diagnosis, which could be excluded after optimized treatment of reflux disease, with clinical and radiological improvement. Clinical management of patients with collagen diseases requires clinician skills to identify the natural history and understand its nuances. This is a common situation in clinical practice, but with a few discussions in international literature.

Lúpus Eritematoso Sistêmico: Revisão das Manifestações Cardiovasculares / Systemic Lupus Erythematosus: Review of Cardiovascular Aspects

Lúpus eritematoso sistêmico (LES) é uma condição autoimune com processo fisiopatológico complexo, no qual sua atividade inflamatória é potencializadora da doença coronariana através de inflamação sistêmica, disfunção endotelial e predisposição à trombose. O acometimento cardiovascular no LES não é critério diagnóstico, sendo considerado somente como dano já estabelecido em longo prazo de doença. O objetivodeste artigo é destacar a importância da visão clínica para a identificação precoce do acometimento cardiovascular no LES. É feita uma análise crítica da abordagem cardiológica no LES, com ênfase nos aspectos clínicos, biomarcadores cardiovasculares e genética e solicitação racional dos exames complementares. Aparticularidade dos pacientes com nefrite lúpica e síndrome do anticorpo antifosfolipídeo também é destacada.A percepção do dano cardíaco subclínico é fundamental para interromper o ciclo de agressão miocárdica e evitar progressão de doença cardíaca.

Systemic lupus erythematosus (SLE) is an autoimmune condition with a complex pathophysiological process in which its inflammatory activity is an enhancer of coronary disease by systemic inflammation, endothelial dysfunction and predisposition to thrombosis. Thecardiovascular involvement in SLE is not a diagnostic criterion and is considered only as damage established in the long-term of the disease. The objective of this study is to highlight the importance of clinical vision for the early identification of cardiovascular involvement in SLE. A critical analysis of the cardiac approach in SLE, with emphasis on clinical aspects, cardiovascular biomarkers and genetics and rational request of additional tests. The particularity of patients with lupus nephritis and antiphospholipid antibodysyndrome is also highlighted. The perception of subclinical cardiac damage is critical for interrupting the cycle of myocardial injury and to avoid progression of heart disease.
