natriuretic-peptide--brain and Cushing-Syndrome

Cardiovascular complications, including cardiomegaly, myocardial ischemia and left ventricular hypertrophy, are some of the major determinants of the mortality rate in patients with Cushing's syndrome. We herein report the case of a patient with Cushing's syndrome caused by an adrenal adenoma who presented with congestive heart failure secondary to dilated cardiomyopathy. Follow-up echocardiography showed a marked improvement in the left ventricular cardiac function, and the plasma B-type natriuretic peptide (BNP) levels regressed after successful treatment. "Reversible" dilated cardiomyopathy is rarely associated with Cushing's syndrome; however, it should be recognized. Administering appropriate treatment in a timely manner can reverse this cardiomyopathy along with the other symptoms of Cushing's syndrome.

To evaluate frequency of heart failure syndrome in patients with endogenous hypercortisolism and to establish relationship between effective treatment for hypercortisolism and regression of heart failure with particular emphasis on the observation of NT-proBNP and ST2 levels.. 56 patients with endogenous hypercortisolism (45 female, mean age 47 years [36; 55] hospitalized with endogenous hypercortisolism to National Medical Research Center for Endocrinology were enrolled in the study. All patients underwent comprehensive clinical investigation including expert echocardiography with speckle tracking and evaluation of NT-proBNP and ST2 cardiac biomarkers at baseline and 6 months after surgical treatment.. According to clinical data and elevated biomarkers of cardiac stress 28 out of 56 patients (50%) at baseline met the criteria for heart failure. 20 patients were included in the final analysis. Follow-up investigation with focus on changes in NT-proBNP and ST2 levels demonstrated that surgical correction of endogenous hypercortisolism resulted in resolution of heart failure syndrome in 11 patients (55%).. These preliminary data suggest that signs and symptoms of heart failure are observed in patients with endogenous hypercortisolism in about half the cases. Surgical correction results in resolution of heart failure in approximately two thirds of the cases. Prospective evaluation NT-proBNP and ST2 levels may provide important diagnostic and prognostic information in patients with endogenous hypercortisolism.. Цель. Изучить частоту встречаемости сердечной недостаточности у пациентов с эндогенным гиперкортицизмом (ЭГ) и оценить взаимосвязь эффективного лечения ЭГ и регресса сердечной недостаточности, учитывая динамику биомаркеров сердечной недостаточности N-терминального фрагмента мозгового натрийуретического пептида (NT-proBNP) и стимулирующего фактора роста, экспрессируемого геном 2 (ST2). Материалы и методы. В исследование включены 56 пациентов с ЭГ (45 женщин, средний возраст 47 лет [36; 55]), госпитализированных в ФГБУ «НМИЦ эндокринологии» с подтвержденным диагнозом ЭГ с октября 2018 по февраль 2020 г. Всем пациентам при включении в исследование и через 6 мес после хирургического лечения проведены стандартное клинико-инструментальное обследование, эхокардиография с определением глобальной продольной деформации миокарда. Кроме того, определены биомаркеры сердечной недостаточности – NT-proBNP и ST2. В финальный анализ включены 24 пациента, госпитализированные для повторного обследования через 6 мес. Результаты. На основании клинических данных и повышения уровней NT-proBNP и ST2 у 28 (50%) из 56 пациентов диагностирована сердечная недостаточность. Ремиссия ЭГ подтверждена у 20 пациентов. Последующие исследования с акцентом на изменения уровней NT-proBNP и ST2 продемонстрировали, что стойкая ремиссия ЭГ привела к регрессу сердечной недостаточности у 11 (55%) пациентов. Заключение. Предварительные данные свидетельствуют о том, что признаки и симптомы сердечной недостаточности наблюдаются у больных ЭГ примерно в 1/2 случаев. Стойкая ремиссия ЭГ приводит к регрессу сердечной недостаточности в 1/2 случаев. Проспективная оценка уровней NT-proBNP и ST2 может дать важную диагностическую и прогностическую информацию у пациентов с ЭГ.

even after successful surgical cure, Cushing's Syndrome (CS) may induce cardiovascular (CV) diseases including hypertension, or elicit onset of CV risk factors, such as obesity.. to evaluate some early markers of CV dysfunction in adolescent girls before and after successful surgical cure of CS; to compare after surgery data with those of a control group (C) of healthy young girls.. 23 girls affected by CS were enrolled (range: 11-17 years; mean: 14.3 +/- 1.7 years). Epicardial fat thickness (EFT), intima-media thickness (IMT), N-terminal pro B-type natriuretic peptide (NT-proBNP) were assessed; transthoracic echocardiogram coupled with Tissue Doppler imaging (TDI) was performed. RESULTS (CS before surgery vs. CS after surgery): EFT (p < 0.05). (CS after surgery vs. C): EFT (p = 0.0001); IMT (p = 0.0001); NT-proBNP (p = 0.0001). TDI: isovolumetric relaxation time (p = 0.001); isovolumetric contraction time (p = 0.001); myocardial performance index (p = 0.001). Significant correlations: NT-proBNP with IRT (r = 0.45, p = 0.026 ), ICT (r = 0.47, p = 0.028), and myocardial performance index (r = 0.51, p = 0.0032).. important structural and functional modifications of heart and vessels are present in young female CS despite successful surgical cure, even in paediatric age. It underlines their significantly higher cardiovascular risk. Our findings confirm that EFT, IMT, NT-proBNP and TDI diastolic parameters, not previously tested in paediatric CS, are early markers of cardiovascular dysfunction. Because of its relationship with TDI, the assessment of NT-proBNP proves to be the best marker in detecting a cardiovascular dysfunction in this specific population.
