Respostas hemodinâmicas do método Pilates em hipertensos: uma revisão sistemática / Hemodynamic responses of the Pilates method in hypertensens: a systematic review

O objetivo do presente estudo foi levantar, na literatura atual, estudos relevantes que identifiquem as possíveis respostas hemodinâmicas encontradas em indivíduos hipertensos praticantes do Método Pilates. A revisão sistemática conduzida conforme as recomendações PRISMA em cinco bases de dados eletrônicas (PEDro, PubMed, SciELO, LILACS e Cochrane), disponibilizado desde o início das bases até Março de 2019, com descritores MESH conforme segue: [("Adult" OR "Young adult" OR "Middle Aged" OR "Aged" OR "Elderly") AND ("exercise movement techniques" OR "Pilates-Based Exercises" OR "Pilates Training") AND ("Hemodynamics" OR "Heart Rate" OR "Cardiac Chronotropy" OR "Heart Rate Control" OR "hypertension" OR "Blood Pressure" OR "High Blood Pressure" OR "Systolic Pressure" OR "Diastolic Pressure" OR "High Blood Pressure" OR "Pulse Rate Determination")], posteriormente ajustado para as demais bases. Busca complementar manual nas referências dos artigos incluídos na pesquisa e Google Scholar. Foram incluídos estudos de intervenção, com idade maior ou igual a 18 anos; diagnóstico de hipertensão arterial sistêmica (HAS); submetidos a exercícios de pilates solo e/ou pilates aparelhos como método de intervenção e incluído a descrição de análise das variáveis hemodinâmicas de pressão arterial (PA), frequência cardíaca (FC) e duplo produto (DP). Após processo de seleção foi selecionado apenas um único estudo que tenha contemplado todos os critérios de elegibilidade, totalizando 44 indivíduos do sexo feminino, com média de idade de 50,5 anos (±6,3 anos), hipertensas com utilização de medicação, onde 22 foram submetidas ao pilates solo e 22 permaneceram no grupo controle. O estudo apresentou resultados positivos na frequência cardíaca (FC), pressão arterial (PA) e no duplo-produto (DP) em comparação ao grupo controle. Apesar do número limitado de manuscritos encontrados nesta revisão, os resultados das variáveis hemodinâmicas nos levam a considerar plausível a utilização do Mat pilates em pacientes com HAS. Entretanto, novos estudos devem ser realizados para a confirmação dos achados...(AU)

The aim this study was to raise in the current literature relevant studies that identify the possible hemodynamic responses found in hypertensive individuals practicing the Pilates Method. The systematic review conducted according to PRISMA recommendations in five electronic databases (PEDro, PubMed, SciELO, LILACS and Cochrane), available from the beginning of the databases until March 2019, with MESH descriptors as follows: [("Adult "OR" Young adult "OR" Middle Aged "OR" Aged "OR" Elderly ") AND (" Exercise Movement Techniques "OR" Pilates-Based Exercises "OR" Pilates Training ") AND (" Hemodynamics "OR" Heart Rate " OR "Cardiac Chronotropy" OR "Heart Rate Control" OR "Hypertension" OR "Blood Pressure" OR "High Blood Pressure" OR "Systolic Pressure" OR "Diastolic Pressure" OR "High Blood Pressure" OR "Pulse Rate Determination")] , later adjusted to the other bases. Manual complementary search in the references of the articles included in the search and Google Scholar. Intervention studies, 18 years of age or older were included; diagnosis of systemic arterial hypertension (SAH); submitted to solo pilates exercises and / or pilates apparatus as intervention method and included the description of analysis of hemodynamic variables of blood pressure (BP), heart rate (HR) and double product (SD). After the selection process, only one study was selected that met all the eligibility criteria, totaling 44 female individuals, with a mean age of 50.5 years (± 6.3 years), hypertensive with medication use, where 22 were submitted to solo pilates and 22 remained in the control group. The study showed positive results in heart rate (HR), blood pressure (BP) and double product (SD) compared to the control group. Despite the limited number of manuscripts found in this review, the results of hemodynamic variables lead us to consider the use of Mat pilates in patients with hypertension to be plausible. However, further studies should be performed to confirm the findings...(AU)

Cardiovascular dysfunction and liver transplantation / 대한마취과학회지

Cardiovascular complications have emerged as the leading cause of death after liver transplantation, particularly among those with advanced liver cirrhosis. Therefore, a thorough and accurate cardiovascular evaluation with clear comprehension of cirrhotic cardiomyopathy is recommended for optimal anesthetic management. However, cirrhotic patients manifest cardiac dysfunction concomitant with pronounced systemic hemodynamic changes, characterized by hyperdynamic circulation such as increased cardiac output, high heart rate, and decreased systemic vascular resistance. These unique features mask significant manifestations of cardiac dysfunction at rest, which makes it difficult to accurately evaluate cardiovascular status. In this review, we have summarized the current knowledge of heart and liver interactions, focusing on the usefulness and limitations of cardiac evaluation tools for identifying high-risk patients.

Consideraciones anestésicas en la anomalía de Ebstein / Anesthetic considerations in Ebstein's anomaly

Introducción: la anomalía de Ebstein es una rara malformación congénita cardiaca, definida por un desplazamiento apical de las valvas septal y posterior de la válvula tricúspide hacia el interior del ventrículo derecho, en vez de hacerlo a nivel del anillo auriculoventricular, lo cual conlleva un aumento del volumen de la aurícula derecha (megaurícula) a expensas de una reducción del tamaño del ventrículo del mismo lado (auriculización del ventrículo). Causa una significante regurgitación tricuspídea y reducción de la capacidad funcional del ventrículo, dilatación atrioventricular derecha, con arritmias auriculares y ventriculares, las que tienden a hacerse resistentes en ocasiones, o de difícil tratamiento. El desplazamiento del orificio valvular tricuspídeo produce una división del ventrículo derecho en una porción integrada al atrio derecho, lo que constituye la porción atrializada del ventrículo derecho, en tanto la porción apicotrabecular y de salida constituye su parte funcional. Objetivo: presentar la evolución clínico-anestesiológica de una paciente con anomalía de Ebstein. Caso clínico: paciente de 69 años de edad programada para cirugía electiva en dos ocasiones por diferentes enfermedades oncológicas, portadora de anomalía de Ebstein. Antecedentes de tromboembolismo pulmonar, tres cirugías cardiacas, diabetes mellitus e hipertensión arterial, enfermedad arterial aterosclerótica estable e infarto cerebral media derecha embólico. Se evitaron aquellas condiciones que aumenten el trabajo cardiaco y el consumo de oxígeno. Conclusiones: el desafío que representa para el anestesiólogo, aquellos pacientes que sufren anomalía de Ebstein puede variar de paciente a paciente, en dependencia del estado físico, el tipo de enfermedad y las técnicas de monitorización(AU)

Introduction: Ebstein's anomaly is a rare congenital cardiac malformation, defined by an apical displacement of the septal and posterior leaflets of the tricuspid valve into the right ventricle, instead of at the level of the atrioventricular ring, which leads to an increase of the volume of the right atrium (mega atrium) at the expense of a size reduction for the ventricle on the same side (auriculization of the ventricle). It causes a significant tricuspid regurgitation and reduction of the functional capacity of the ventricle, right atrioventricular dilation, with atrial and ventricular arrhythmias, which tend to become resistant at times, or difficult to treat. The displacement of the tricuspid valve orifice produces a division of the right ventricle in a portion integrated to the right atrium, which constitutes the atrialized portion of the right ventricle, while the apico-trabecular and exit portion constitutes its functional part. Objective: To present the clinical-anesthesiological evolution of a patient with Ebstein's anomaly. Clinical case: A 69-year-old patient, with Ebstein's anomaly, who was scheduled for elective surgery on two occasions for different oncological diseases. History of pulmonary thromboembolism, three cardiac surgeries, diabetes mellitus and arterial hypertension, stable atherosclerotic arterial disease, and right middle cerebral infarction. Conditions that increase cardiac work and oxygen consumption were avoided. Conclusions: The challenge patients suffering from Ebstein's anomaly represent for the anesthesiologist can vary from patient to patient, depending on the physical state, the type of disease, and the monitoring techniques(AU)

Cardiovascular beriberi: rare cause of reversible pulmonary hypertension / 영남의대학술지

Cardiovascular beriberi is caused by thiamine deficiency and usually presents as high cardiac output failure associated with predominantly right-sided heart failure and rapid recovery after treatment with thiamine. Because of its rarity in developed countries, the diagnosis can often be delayed and missed. We recently experienced a case of cardiovascular beriberi with pulmonary hypertension which successfully treated with thiamine infusion. A 50-year-old man with chronic heavy alcoholics was refered to our department for dyspnea with mental change. Echocardiography showed marked right ventricular (RV) dilatation and flattening of the interventricular septum with a D-shaped deformation of the left ventricle. Moderate tricuspid valve regurgitation was found and estimated RV systolic pressure was 52 mm Hg. Because of his confused mentality and history of chronic alcohol intake, neurological disorder due to thiamine deficiency was suspected and intravenous thiamine was administered and he continuously received a daily dose of 100 mg of thiamine. Follow up echocardiography showed marked reduction of RV dilatation and improvement of a D-shaped deformation of the left ventricle. He finally diagnosed as cardiovascular beriberi on the basis of dramatic response to intravenous thiamine. Thiamine deficiency can cause reversible pulmonary hypertension, and can still be encountered in the clinical setting. Thus high index of suspicion is critically needed for diagnosis.

Acquired arteriovenous fistula of the right common iliac artery and left common iliac vein and bilateral lower extremity deep venous thrombosis in a woman presenting as high output heart failure

Acquired intraabdominal arteriovenous fistula (AVF) is a rare disorder where the communication most commonly occurs between the abdominal aorta and inferior vena cava. Ilioiliac AVF has been reported previously, but is exceedingly rare. We present a case of acquired arteriovenous fistula of the right common iliac artery and left common iliac vein with extensive collateralization (ilioiliac AVF) in a 36-year-old female who presented with symptoms of high output congestive heart failure 18 years after sustaining an abdominal gunshot wound.

High Cardiac Output Heart Failure Induced by Chronic Severe Anemia / 대한내과학회지

High cardiac output heart failure (HCOHF) occurs in the setting of increased cardiac output, such as with chronic anemia, hyperthyroidism, beriberi, pregnancy, and an arteriovenous (AV) fistula. Of these, chronic anemia is a rare cause of HCOHF and its pathophysiology remains unknown. This report is about a patient with chronic anemia who presented with heart failure and severe tricuspid regurgitation. The severity of the tricuspid regurgitation and the patient's symptoms and signs were improved on correcting the anemia.

Síndrome antifosfolípido catastrófico y falla cardíaca aguda. Caso clínico / Catastrophic antiphospholipid syndrome and acute heart failure. Report of a case

A 33 years old woman was admitted to the hospital after four days with cough, dyspnea, orthopnea and hemoptysis. Blood pressure was 170/90 mmHg, pulse was 112 and temperature was normal. She had cyanosis and a left ventricular gallop, without heart murmurs. A chest radiograph revealed pulmonary edema and echocardiogram showed a global left ventricular systolic disfunction. Oxygen and furosemide were started, but cardiopulmonary collapse ensued. The patient was supported with mechanical ventilation and treated with inotropic drugs. A right sided cardiac catheterization showed pulmonary wedge pressure of 18 mmHg and a cardiac index of 3 l/min/m2. The levels of creatinine and urea nitrogen were elevated and a urine protein was 97 mg/dl. Coagulation tests were normal except by a positive lupic anticoagulant. Markers of connective tissue diseases or vasculitis were negatives. The clinical evolution suggested that a catastrophic antiphospholipid syndrome was ongoing. Intravenous corticoids, gammaglobulin and cyclophosphamide were administered with transient improvement. On her fourth day of treatment, the patient presented sudden pulmonary bleeding and embolism. A plasmapheresis was performed with improvement of renal, cardiac and pulmonary function. After this episode, the patient has been treated with prednisone and oral anticoagulants treatment for the last two years, without further clinical events.

Validity and reliability of cardiac output by arterial thermodilution and arterial pulse contour analysis compared with pulmonary artery thermodilution in intensive care unit.

Cardiac output measurement has a significat role in the critical care setting. The standard of measurement currently is via pulmonary arterial catheter but it has some technical difficulties and serious complications. The authors performed a new method of measurement that used a catheter in a femoral artery. The results of both methods performed simultaneously in 10 surgical intensive care patients every 2 hours for 24 hours were compared. There was high correlation between the two methods, r = 0.97. The average difference of the cardiac output values was 0.46 l/min with standard deviation 0.56 l/min.

Beriberi cardiovascular agudo (shoshin-beriberi) / Acute cardiovascular beriberi (shoshin-beriberi)

Beriberi (BB), thiamine deficiency, has been described in the Asian literature in the 17th century and is characterized by peripheral neuropathy and muscle weakness, also called "dry" beriberi (BB) to differentiate it from "wet" BB, with essentially cardiovascular manifestations. Wet can be either "classic" wet BB in which signs and symptoms of right-sided heart failure with normal or high cardiac output are the presenting features or the "shoshin" BB variant with severe biventricular failure and metabolic acidosis, which must be treated early to prevent the rapid development of low cardiac output failure and sudden death. In this case, we report a 58 year old alcoholic woman who developed dyspnea, oliguria, edema, cardiac failure with high output, metabolic acidosis, renal tubular dysfunction and serum lactate level of 5.6 mEq/L. Neurological examination revealed peripheral neuropathy in the lower legs and cognitive alteration. She was treated with a loading dose of 100 mg of intravenous thyamine and responded with a marked increase in urine output, correction of acidosis, reduction in pulmonary-capillary wedge pressure and a change of the hemodynamic pattern. We conclude that shoshin-BB is uncommonly encountered but not widely recognized. In lactic acidosis and/or hyperdynamic circulation without any other apparent etiology in patients with possible vitamin B1 deficiency, the diagnosis of BB must be considered and thiamine should be administered

Anesthesia for Liver Transplantation in Patients with Hepatopulmonary Syndrome / 대한마취과학회지

Hepatopulmonary syndrome is essentially the triad of liver disease, pulmonary vascular dilations and abnormal arterial oxygenation, which can result in severe hypoxia. We managed two cases of 9 and 49-year-old males for liver transplantation with hepatopulmonary syndrome. Preoperative evaluation showed decreased diffusion capacity of carbon monooxide and severe hypoxemia, while breathing room air (PaO2 < 60 mmHg) but they responded to oxygen therapy. The pulmonary vascular resistance was low, consistent with an intrapulmonary vascular shunt but the pulmonary artery pressure was normal, reflecting a high cardiac output. Intraoperative oxygenation was satisfactory (PaO2 of 100 - 200 mmHg) in spite of a high shunt fraction (Qs/Qt 18.5 +/- 9.2%). This means that the impairment in gas exchange is not the result of a true shunt, suggesting the presence of a functional shunt, which is characterized by diffusion-perfusion impairment. The intraoperative course was uneventful in the two patients and they are in a successful postoperative course. In case 1, the hypoxemia was resolved promptly, but in case 2, it was persistent for sixteen months after transplantation. The hypoxemia itself in hepatopulmonary syndrome is not regarded as a contraindication to liver transplantation. (Korean J Anesthesiol 2001; 40: 677 ~ 683)

Increased Cerebrovascular Resistance in Liver Cirrhosis and Ascites / 대한간학회지

BACKGROUND/AIMS: Portal hypertension in cirrhosis is associated with a hyperdynamic circulation, which is characterized by hypervolemia, high cardiac output, arterial hypotension and low peripheral vascular resistance. These circulatory abnormalities are thought to be secondary to a splanchnic arteriolar vasodilation related to the increase in portal pressure. Studies assessing regional hemodynamics in patients of cirrhosis with ascites have shown vasoconstriction in the renal circulation and in peripheral vascular territory. This study was designed to assess the cerebral vascular resistance in cirrhotic patients with ascites. METHODS: The resistive index in the middle cerebral artery and in a renal interlobar artery were measured by Doppler ultrasonography in 12 cirrhotic subjects without ascites, 23 cirrhotic subjects with ascites, and 8 healthy subjects. The arterial blood pressure and plasma renin and norepinephrine concentration, which reflect the activity of the renin-ngiotensin and sympathetic nervous systems respectively, were also measured. RESULTS: The resistive index in the middle cerebral artery were significantly higher in cirrhotic patients with ascites (0.58 +/- 0.04, mean +/- standard deviation) than in cirrhotic patients without ascites (0.53 +/- 0.02, p<0.01) and in control subjects (0.50 +/- 0.05, p<0.01). The resistive index in the middle cerebral artery showed direct correlation with renal resistive index (r = 0.52, p<0.01), plasma renin activity (r = 0.44, p<0.01) and norepinephrine (r = 0.33, p<0.05). The resistive index in the middle cerebral artery showed an inverse correlation with mean arterial pressure (r = -.59, p<0.01). CONCLUSION: The results suggest that in patients of cirrhosis with ascites, independent of the amount of ascites, there is a cerebral vasoconstriction which is related with the arterial hypotension and the overactivity of vasoconstrictor systems.

Valvular Regurgitation in Patients with Graves' Disease

The high cardiac output state and an increased incidence of atrial fibrillation are well-known cardiovascular complications of Graves' disease, whereas the valvular complications are less well recognized. With 2D color Doppler echocardiography, the cardiac and valvular function of 39 patients with Graves' disease were evaluated and our data were compared with previous Kage's study. The incidences of mitral regurgitation (MR) and tricuspid regurgitation (TR) in patients with Graves' disease were 54% and 51%, respectively. There was no correlation between the incidence of MR and ventricular dilatation. In patients with congestive heart failure (CHF), the incidences of severe TR and atrial fibrillation were significantly higher than in patients without CHF. The incidences of TR and MR in patients with Graves' disease were not different by thyroid function status (hyperthyroid vs. euthyroid). We suggest that the examination for TR and MR in patients with Graves' disease is important not only their high prevalence but also their clinical significance as a risk factor for CHF.

Insuficiencia cardíaca de alto gasto en el mieloma múltiple / High output heart failure in multiple myeloma

Se presenta el caso clínico de una paciente portadora de un mieloma múltiple sin cardiopatía estructural previa que en la evolución instala un sindrome de insuficiencia cardíaca por falla diastólica y con alto gasto cardíaco. Dicha presentación documentada por métodos paraclínicos aceptados universalmente, tiene un modelo fisiopatológico particular que merece destaque, dado que tanto en el motivo de descompensación, como la instalación de insuficiencia cardíaca en ausencia de cardiopatía de fondo, y el alto gasto, se intentan explicar unitariamente por sustancias segregadas por la discrasia plasmocitaria misma, shunts arteriovenosos intramedulares o intraesplénicos y la anemia acompañante entre otros factores. Su estudio posee peculiaridades, y su tratamiento además de las medidas habituales de restricción sódica, diuréticos, eventualmente digitálicos y vasodilatadores, requiere ser acompañado de quimioterapia para yugular las manifestaciones del síndrome
