Abstract: En | Text: En | PDF: En

ABSTRACT Giant cell arteritis (GCA) is a type of chronic vasculitis that affects medium and large-caliber arteries, frequently related to aortic involvement and, consequently, to aneurysm formation. However, associated valvulitis with giant cells is uncommon. We describe the case of a 50-year-old female patient with aortic aneurysm and valvular insufficiency, whose anatomopathological examination revealed giant-cell aortic valvulitis associated with giant cell aortitis.

Abstract: En | Text: En | PDF: En

ABSTRACT Currently, there is growing evidence in the literature warning of misdiagnosis involving amyloidosis and chronic inflammatory demyelinating polyneuropathy (CIDP). Although inducing clinical manifestations outside the peripheral nervous system, light chain and transthyretin amyloidosis may initially present with peripheral neuropathy, which can be indistinguishable from CIDP, leading to a delay in the correct diagnosis. Besides, the precise identification of the amyloid subtype is often challenging. This case report exemplifies clinical and laboratory pitfalls in diagnosing amyloidosis and subtyping amyloid, exposing the patient to potentially harmful procedures.

Resumo Evidências recentes sugerem que a amiloidose cardíaca é uma doença amplamente subdiagnosticada, particularmente na sua forma ligada à transtirretina, podendo ser uma causa comum de insuficiência cardíaca com fração de ejeção preservada (ICFEP) no idoso. Os novos paradigmas sobre a doença incluem o desenvolvimento de novas terapias específicas que modificam a história natural da doença. Este artigo traz uma síntese destes novos conceitos.

Abstract Recent evidence suggests cardiac amyloidosis (CA) is a mostly underdiagnosed condition, particularly in the transthyretin-mediated form, and is a frequent cause of heart failure with preserved ejection fraction (HFpEF) in the elderly. New paradigms about CA also involve the development of disease-modifying specific therapies. This article summarizes these new concepts.

Abstract: En | Text: En | PDF: En

Abstract Background: Galectin-3 is the designation given to the protein that binds to ß-galactosides, expressed by activated macrophages and described as a cardiac fibrosis mediator. In hypertrophic cardiomyopathy (HCM), myocardial fibrosis is an independent predictor of adverse outcome; however, the association between Galectin-3 and myocardial fibrosis has not been studied in this cardiopathy. Objective: To evaluate the association of Galectin-3 and the presence of myocardial fibrosis in a patient with hypertrophic cardiomyopathy. Methods: Galectin-3 was measured in automated equipment using the Elisa technique in 100 participants divided into two groups: 50 patients with hypertrophic cardiomyopathy and 50 healthy control subjects. All patients with hypertrophic cardiomyopathy underwent magnetic nuclear resonance with the late enhancement technique to investigate myocardial fibrosis. For the statistical analysis, p values < 0.05 were considered statistically significant. Results: Galectin-3 levels were low and did not show significant differences between patients with hypertrophic cardiomyopathy and the control group, 10.3 ± 3.1 ng/dL and 11.3 ± 2.6 ng/dL (p = 0.12) respectively. Myocardial fibrosis was a common finding and was identified in 84% (42/50) of patients with HCM, but no differences were observed between Galectin-3 levels when comparing patients with and without fibrosis, 10.3 ± 2.4 ng/dL and 10.1 ± 2.1 ng/dL (p = 0.59). Conclusion: The results did not show an association between Galectin-3 and myocardial fibrosis in patients with hypertrophic cardiomyopathy, suggesting that non-inflammatory mechanisms of myocardial fibrosis formation and cardiac remodeling are involved in this cardiopathy.

Fundamento:A doença de Chagas é uma causa de miocardiopatia dilatada, sendo ainda pouco conhecida a função do átrio esquerdo (AE) nessa doença.Objetivo:Avaliar as diferenças nas funções do AE (reservatório, conduto e bomba) e sua correlação com os parâmetros ecocardiográficos das funções sistólica e diastólica do ventrículo esquerdo (VE).Método:10 controles (GC) e os seguintes pacientes com doença de Chagas: 26 com a forma indeterminada (GI); 30 com alterações eletrocardiográficas (GII); e 19 com disfunção de VE (GIII). Todos os pacientes foram submetidos a ecocardiografia bidimensional e em modo M, Doppler pulsado e Doppler tecidual.Resultados:Função de reservatório (fração de esvaziamento total: FET) (p < 0,0001), mais baixa no GIII do que no GC (p = 0,003), GI (p < 0,001) e GII (p < 0,001). Função de conduto (fração de esvaziamento passivo: FEP) (p = 0,004), mais baixa no GIII (GIII e GC, p = 0.06; GI e GII, p = 0.06; e GII e GIII, p = 0,07). Função de bomba (fração de esvaziamento ativo: FEA) (p = 0,0001), mais baixa no GIII do que no CG (p = 0,05), GI (p<0,0001) e GII (p = 0,002). Observou-se uma correlação negativa entre E/e’média e as funções de reservatório e de bomba (FET e FEA), e uma correlação positiva entre as ondas e’média e s’ (paredes septal e lateral) e as funções de reservatório, conduto e bomba.Conclusão:Observou-se comprometimento das funções do AE na miocardiopatia chagásica.

Background:Chagas disease is a cause of dilated cardiomyopathy, and information about left atrial (LA) function in this disease still lacks.Objective:To assess the different LA functions (reservoir, conduit and pump functions) and their correlation with the echocardiographic parameters of left ventricular (LV) systolic and diastolic functions.Methods:10 control subjects (CG), and patients with Chagas disease as follows: 26 with the indeterminate form (GI); 30 with ECG alterations (GII); and 19 with LV dysfunction (GIII). All patients underwent M-mode and two-dimensional echocardiography, pulsed-wave Doppler and tissue Doppler imaging.Results:Reservoir function (Total Emptying Fraction: TEF): (p <0.0001), lower in GIII as compared to CG (p = 0.003), GI (p <0.001) and GII (p <0.001). Conduit function (Passive Emptying Fraction: PEF): (p = 0.004), lower in GIII (GIII and CG, p = 0.06; GI and GII, p = 0.06; and GII and GIII, p = 0.07). Pump function (Active Emptying Fraction: AEF): (p = 0.0001), lower in GIII as compared to CG (p = 0.05), GI (p<0.0001) and GII (p = 0.002). There was a negative correlation of E/e’average with the reservoir and pump functions (TEF and AEF), and a positive correlation of e’average with s’ wave (both septal and lateral walls) and the reservoir, conduit and pump LA functions.Conclusion:An impairment of LA functions in Chagas cardiomyopathy was observed.

Métodos: Estudo retrospectivo. Foram avaliadas as seguintes medidas: ângulo de Cobb na radiografia em incidência anteroposterior das três curvas (torácica proximal, torácica principal e lombar), ângulo de Cobb na radiografia em perfil das duas curvas: cifose torácica (T5-T12) e da lordose lombar (T12-S1). Resultados: Do total dos 25 pacientes avaliados no pré-operatório, quatro (16%) eram hipocifóticos, 20 pacientes (80%) eram normocifóticos e apenas um (4%) era hipercifótico. No caso dos pacientes hipocifóticos e hipercifóticos, obtivemos correção satisfatória da cifose torácica em 100% dos casos, os quais se apresentaram normocifóticos no resultado final. Os pacientes normocifóticos permaneceram com esse mesmo padrão de cifose torácica em sua totalidade durante o seguimento. Conclusão: A avaliação radiográfica da cifose torácica em portadores de escoliose idiopática do adolescente tratada cirurgicamente com parafusos pediculares em todas as vértebras envolvidas na artrodese demonstrou resultados satisfatórios com relação à correção da cifose torácica.

Objectives: To analyze radiographically the postoperative kyphosis from patients undergoing surgical treatment for AIS with pedicle screws in all vertebrae included in the arthrodesis. Methods: Retrospective study. The following measurements were evaluated: Cobb angle in anteroposterior radiograph of the three curves (proximal thoracic, main thoracic, and lumbar), Cobb angle in the lateral view of the two curves: thoracic kyphosis (T5-T12) and lumbar lordosis (T12-S1). Results: Of the 25 patients evaluated preoperatively, four (16%) were hypokyphotic, 20 patients (80%) were normokyphotic and only one (4%) was hyperkyphotic. For hypokyphotic and hiperkyphotic patients a satisfactory correction of thoracic kyphosis was obtained in 100% of cases, which was preserved in the final result. The same pattern of thoracic kyphosis was observed for all normokyphotic patients throughout the follow-up. Conclusion: Radiographic evaluation of thoracic kyphosis in patients with AIS treated surgically with pedicle screws in all vertebrae showed satisfactory results with respect to the correction of thoracic kyphosis.

FUNDAMENTO: Na cardiomiopatia hipertrófica (CMH), a fibrose miocárdica intersticial é uma importante alteração histológica que tem sido associada com morte súbita e evolução para dilatação. OBJETIVO: Avaliar, prospectivamente, o valor prognóstico da fração de colágeno na CMH. MÉTODOS:Biópsia endomiocárdica do ventrículo direito foi realizada com sucesso em 21 pacientes sintomáticos com CMH. A fração de volume de colágeno (FVC) miocárdico foi determinada por histologia. A FVC também foi determinada em fragmentos de nove corações normais de indivíduos falecidos por causas não-cardíacas. Os pacientes foram divididos em grupos supra e infra-medianos em relação à FVC, sendo comparadas as características clínico-ecocardiográficas e as curvas de sobrevida. RESULTADOS: Entre os pacientes, a FVC variou de 1,86% a 29,9%, mediana 6,19%; nos corações normais, de 0,13% a 1,46%, mediana 0,36% (p<0,0001 entre CMH e controle). Não foram observadas correlações significativas entre FVC e medidas ecocardiográficas basais. Pacientes com FVC<6,19% e FVC>6,19% foram comparados e não foram observadas diferenças basais. Entretanto, após um período de seguimento médio de 110 meses, quatro mortes ocorreram (duas súbitas, duas por insuficiência cardíaca) no grupo com FVC maior, enquanto os pacientes do grupo com FVC menor estavam vivos ao final do período (p=0,02). CONCLUSÃO:Pela primeira vez, a fibrose miocárdica foi prospectivamente associada a um pior prognóstico em pacientes com CMH. Esforços devem ser direcionados para quantificação da fibrose miocárdica na CMH, assumindo que a associação com o prognóstico pode auxiliar na estratificação de risco para implante de desfibrilador e na prescrição de fármacos potencialmente reparadores miocárdicos.

BACKGROUND: In hypertrophic cardiomyopathy (HCM), interstitial myocardial fibrosis is an important histological modification that has been associated with sudden death and evolution toward myocardial dilation. OBJECTIVE:To prospectively evaluate the prognostic value of the collagen volume fraction in HCM. METHODS: An endomyocardial biopsy of the right ventricle was successfully performed in 21 symptomatic patients with HCM. The myocardial collagen volume fraction (CVF) was determined by histology. The CVF was also determined in fragments of nine normal hearts from subjects deceased from non-cardiac causes. The patients were divided into above-median CVF and below-median CVF groups, and their clinical and echocardiographic characteristics and survival curves were compared. RESULTS: Among the patients, the CVF ranged from 1.86% to 29.9%, median 6.19%; in normal hearts, from 0.13% to 1.46%, median 0.61% (p <0.0001 between HCM and control). There were no significant correlations between CVF and baseline echocardiographic measures. Patients with CVF < 6.19% and CVF> 6.19% were compared and no baseline differences were observed. However, after an average follow-up period of 110 months, four deaths occurred (two sudden, two due to heart failure) in the group with increased CVF, whereas the patients of the group with lower CVF were all alive at the end of the period (p = 0.02). CONCLUSION:For the first time, myocardial fibrosis was prospectively associated with a worse prognosis in patients with HCM. Efforts should be directed to the quantification of myocardial fibrosis in HCM, on the premise that its association with the prognosis can aid in the stratification of risk for defibrillator implantation, and in the prescription of drugs that potentially promote myocardial repair.

FUNDAMENTO: En la cardiomiopatía hipertrófica (CMH), la fibrosis miocárdica intersticial es una importante alteración histológica, que ha sido asociada con muerte súbita y evolución hacia dilatación. OBJETIVO:Evaluar, prospectivamente, el valor pronóstico de la fracción de colágeno en la CMH. MÉTODOS:Se realizó, con éxito, biopsia endomiocárdica del ventrículo derecho en 21 pacientes sintomáticos con CMH. La fracción de volumen de colágeno (FVC) miocárdico se determinó por medio de histología. Se determinó la FVC también en fragmentos de nueve corazones normales de individuos fallecidos por causas no cardiacas. Respecto a la FVC, se dividieron a los pacientes en grupos supra e inframedianos (FVC elevada y FVC baja, respectivamente), y se compararon las características clínicas y ecocardiográficas y las curvas de sobrevida. RESULTADOS: Entre los pacientes, la FVC tuvo variación del 1,86% al 29,9%, con mediana en el 6,19%. Ya en los corazones normales, del 0,13% al 1,46%, mediana en el 0,36% (p<0,0001 entre CMH y control). No se verificaron correlaciones significativas entre FVC y medidas ecocardiográficas basales. Se compararon a pacientes con FVC<6,19% y FVC>6,19%, sin que se observara diferencias basales. Sin embargo, tras un período de seguimiento promedio de 110 meses, cuatro muertes ocurrieron (dos súbitas, y otras dos por insuficiencia cardiaca) en el grupo con FVC mayor, mientras que los pacientes del grupo con FVC menor estaban vivos al final del período (p=0,02). CONCLUSIÓN: Por primera vez, se asoció prospectivamente la fibrosis miocárdica a un peor diagnóstico en pacientes con CMH. Se deben encaminar esfuerzos hacia la cuantificación de la fibrosis en la CMH, al aceptar que la asociación con el pronóstico puede auxiliar tanto en la estratificación de riesgo para implante de desfibrilador, como en la prescripción de fármacos potencialmente reparadores miocárdicos.

Abstract: En | Text: En | PDF: En

OBJECTIVES: We compared left ventricular regional wall motion, the global left ventricular ejection fraction, and the New York Heart Association functional class pre- and postoperatively. INTRODUCTION: Endomyocardial fibrosis is characterized by fibrous tissue deposition in the endomyocardium of the apex and/or inflow tract of one or both ventricles. Although left ventricular global systolic function is preserved, patients exhibit wall motion abnormalities in the apical and inferoapical regions. Fibrous tissue resection in New York Heart Association FC III and IV endomyocardial fibrosis patients has been shown to decrease morbidity and mortality. METHODS: We prospectively studied 30 patients (20 female, 30±10 years) before and 5±8 months after surgery. The left ventricular ejection fraction was determined using the area-length method. Regional left ventricular motion was measured by the centerline method. Five left ventricular segments were analyzed pre- and postoperatively. Abnormality was expressed in units of standard deviation from the mean motion in a normal reference population. RESULTS: Left ventricular wall motion in the five regions did not differ between pre- and postoperative measurements. Additionally, the left ventricular ejection fraction did not change after surgery (0.45±0.13% x 0.43±0.12% pre- and postoperatively, respectively). The New York Heart Association functional class improved to class I in 40% and class II in 43% of patients postoperatively (p<0.05). CONCLUSIONS: Although endomyocardial fibrosis patients have improved clinical symptoms after surgery, the global left ventricular ejection fraction and regional wall motion in these patients do not change. This finding suggests that other explanations, such as improvements in diastolic function, may be operational.

FUNDAMENTO: Ainda que os benefícios clínicos das intervenções coronarianas parecem confirmados, seus efeitos na qualidade de vida (QV) permanecem pouco estudados. OBJETIVO: Avaliar a qualidade de vida (QV) na doença multiarterial coronariana em pacientes submetidos randomicamente a cirurgia, angioplastia ou tratamento clínico. MÉTODOS: Foi utilizando Short-Form Health Survey (SF36) questionnaire em 483 pacientes. Desses, 161 foram revascularizados; 166 receberam angioplastia e 153 tiveram tratamento clínico. RESULTADOS: Na internação, 86% referiam angina; 34%, infarto; e 32% fumavam. Tratamento clínico: 12 pacientes (7,7%) tiveram infarto agudo do miocárdio (IAM); 24 (15,3%) receberam cirurgia; e 19 (12,1%) morreram. Além disso, cinco (3,2%) sofreram AVC e 40 (25,6%) tinham angina. No componente mental, 64,1% melhoram e 30,8% pioram a condição. No componente físico, 70,5% melhoram e 27,6% pioram a condição. Cirurgia: 13 pacientes (8,1%) tiveram IAM, dois (1,2%) receberam cirurgia; 12 (7,4%) morreram. Em adição, nove (5,6%) sofreram AVC e 30 (18,6%) sofriam angina. No componente mental, 72,7% melhoram e 25,5% pioram a condição. No componente físico, 82,6% melhoram e 16,1% pioram a condição. Angioplastia: 18 pacientes (10,9%) tiveram IAM, 51 (30,7%) receberam intervenções e 18 (19,9%) morreram. Além disso, seis (3,6%) sofreram AVC e 35 (21%) relatavam angina. No componente mental, 66,9% melhoram e 26,5% pioram a condição No componente físico, 77,1% melhoram e 20,5% pioram a condição. CONCLUSÃO: Observou-se melhora em todos os domínios e nas três opções terapêuticas. Comparativamente, a cirurgia ofereceu melhor qualidade de vida após quatro anos de seguimento.

BACKGROUND: Although the clinical benefits of coronary interventions seem to be confirmed, their effects on quality of life (QoL) are still scarcely studied. OBJECTIVE: To assess the QoL in multivessel coronary disease in patients randomly undergoing surgery, angioplasty or medical treatment. METHODS: The Short-Form Health Survey (SF-36) questionnaire was answered by 483 patients. Of these, 161 underwent surgical revascularization, 166 underwent angioplasty, and 153 were medically treated. RESULTS: At baseline, 86% of the patients referred angina, 34% referred infarction, and 32% were smokers. Medical Treatment: 12 patients (7.7%) had AMI, 24 (15.3%) underwent surgery, and 19 (12.1%) died. In addition, 5 (3.2%) had stroke, and 40 (25.6%) had angina. As regards the mental component, 64.1% and 30.8% had their condition improved and worsened, respectively. As regards the physical component, 70.5% and 27.6% had their condition improved and worsened, respectively. Surgery: 13 patients (8.1%) had AMI, 2 (1.2%) underwent surgery, and 12(7.4%) died. Also, 9 (5.6%) had stroke and 30 (18.6%) had angina. As regards the mental component, 72.7 % and 25.5% had their condition improved and worsened, respectively. As regards the physical component, 82.6% and 16.1% had their condition improved and worsened, respectively. Angioplasty: 18 patients (10.9%) had AMI, 51 (30.7%) underwent interventions, and 18 (19.9%) died. Additionally, six (3.6%) presented stroke and 35 (21%) reported angina. As regards the mental component, 66.9% and 26.5% had their condition improved and worsened, respectively. As regards the physical component, 77.1% and 20.5% had their condition improved and worsened, respectively. CONCLUSION: Improvement was observed in all domains and in the three therapeutic modalities. Comparatively, surgery had provided a better quality of life after a four-year follow-up.
