RESUMO

INTRODUCTION: Primary graft failure (PGF) is an important contributor to early mortality, accounting for 41% of deaths within the first 30 days after heart transplantation (HT). Donor hypernatremia has been associated with PGF development. However, controversial data exist regarding the impact of sodium deregulation in patient survival after HT. This study aimed to assess the influence of donor hypernatremia on PGF development and to determine the serum sodium level threshold to assist in decision-making for organ procurement. METHODS: The medical record from 200 HT patients and organ donors were retrospectively assessed and categorized by PGF occurrence. Donor sodium levels were compared and cut-off points obtained by receiver operating characteristic (ROC) curve. A multiple logistic regression model was applied to assess the effects of factors and covariates that influence PGF development. RESULTS: Sodium levels of donors were significantly higher in recipients who developed PGF than those who did not develop PGF (162 vs. 153 mmol/L, P = .001). The sodium cut-off value determined by the ROC curve was 159 mmol/L. The group who received organs from donors with a serum sodium concentration ≥159 mmol/L had a higher incidence of PGF (63.3% vs 32.4%, P < .001). Furthermore, donor sodium levels ≥159 mmol/L increased the likelihood of recipients developing PGF by 3.4 times. It is also observed that the incidence of donor smoking addiction was significantly higher in the PGF group (28.6% vs. 11.5%, P = .004) and donor smoking addiction increased the risk of developing PGF by 2.8 times. CONCLUSION: Smoking addiction and the application of suboptimal organs from donors with hypernatremia contribute to primary graft failure in heart transplantation.

RESUMO

INTRODUÇÃO: O treinamento físico melhora a capacidade funcional e a qualidade de vida em pacientes com insuficiência cardíaca crônica (IC). Entretanto, devido à baixa disponibilidade de centros de reabilitação cardíaca e limitações pessoais (custos de transporte, tempo, preferências), a inclusão e a adesão ao treinamento físico supervisionado são baixas, sendo proposto o treinamento domiciliar como alternativa. OBJETIVO: Comparar os efeitos de dois programas de treinamento: um domiciliar e um supervisionado ao longo de 12 semanas sobre a capacidade funcional, atividade física diária e qualidade de vida em pacientes com IC. MÉTODOS: Foram incluídos 23 pacientes com IC (classe funcional NYHA II e III, fração de ejeção do ventrículo esquerdo ≤40%) randomizados em Grupo Domiciliar (GD, n=11) ou Grupo Supervisionado (GS, n=12). Os pacientes realizaram, ao longo de 12 semanas exercícios aeróbios (60-70% da frequência cardíaca de reserva): caminhada para o GD e cicloergômetro para o GS combinados a exercícios resistidos (50% de uma repetição máxima). As variáveis-desfecho foram: pico de consumo de oxigênio e ventilação máxima do teste cardiopulmonar, distância percorrida no teste da caminhada de seis minutos, força muscular do quadríceps, pressão inspiratória máxima, número de passos/dia e qualidade de vida. RESULTADOS: Após 12 semanas,GD e GS apresentaram aumentos significantes (p=0,025) no pico de consumo de oxigênio (0,8 e 3,7 ml/kg/min, respectivamente), na ventilação máxima (11,5 e 15,6 l/min, respectivamente), na distância percorrida (40 e 25 m, respectivamente), na porcentagem de força muscular do quadríceps (21% e 11%, respectivamente) e na qualidade de vida avaliada por meio do questionário Minnesota Living with Heart Failure (1 e 13, respectivamente), sem diferenças entre GD e GS. Entretanto, o GS mostrou melhora na força muscular inspiratória (p=0,042), aumento no número de passos/dia (p=0,001) e no componente de saúde mental do questionário SF-36 (p=0,001) superior ao GD. CONCLUSÕES: O treinamento domiciliar pode ser uma alternativa ao treinamento supervisionado para melhorar a capacidade funcional e a qualidade de vida em pacientes com IC. Além desses benefícios, o treinamento supervisionado foi superior em aumentar a força muscular inspiratória, o número de passos/dia e melhorar os aspectos de saúde mental em pacientes com IC. (AU)

RESUMO

OBJECTIVE: To report our center's experience in the surgical treatment of ventricular reconstruction, an effective and efficient technique that allows patients with end-stage heart failure of ischemic etiology to have clinical improvement and increased survival. METHODS: Observational, clinical-surgical, sequential, retrospective study. Patients with ischemic cardiomyopathy and left ventricular aneurysm were attended at the Heart Failure, Ventricular Dysfunction and Cardiac Transplant outpatient clinic of the Dante Pazzanese Cardiology Institute, from January 2010 to December 2016. Data from 34 patients were collected, including systemic arterial hypertension, ejection fraction, New York Heart Association (NYHA) functional classification (FC), European System for Cardiac Operative Risk Evaluation (EuroSCORE) II value, Society of Thoracic Surgeons (STS) score, ventricular reconstruction technique, and survival. RESULTS: Overall mortality of 14.7%, with hospital admission being 8.82% and late death being 5.88%. Total survival rate at five years of 85.3%. In the preoperative phase, NYHA FC was Class I in five patients, II in 18, III in eight, and IV in three vs. NYHA FC Class I in 17 patients, II in eight, III in six, and IV in three, in the postoperative period. EuroSCORE II mean value was 6.29, P

RESUMO

PURPOSE: Cardiorespiratory fitness is inversely associated with a high risk of cardiovascular disease, all-cause mortality, and mortality attributable to various cancers. It is often estimated indirectly using mathematical formulas for estimating oxygen uptake. Cardiopulmonary exercise testing, especially oxygen uptake, represents the "gold standard" for assessing exercise capacity. The purpose of this report was to develop reference standards for exercise capacity by establishing cardiorespiratory fitness values derived from cardiopulmonary exercise testing in a Brazilian population. We focused on oxygen uptake standards and compared the maximal oxygen uptake [mLO2·kg-1·min-1] values with those in the existing literature. METHODS: A database was constructed using reports from cardiopulmonary exercise testing performed at Fleury laboratory. The final cohort included 18,189 individuals considered to be free of structural heart disease. Percentiles of maximal oxygen uptake for men and women were determined for six age groups between 7 and 84 years. We compared the values with existing reference data from patients from Norway and the United States. RESULTS: There were significant differences in maximal oxygen uptake between sexes and across the age groups. In our cohort, the 50th percentile maximal oxygen uptake values for men and women decreased from 44.7 and 36.3 mLO2·kg-1·min-1 to 28.4 and 22.3 mLO2·kg-1·min-1 for patients aged 20-29 years to patients aged 60-69 years, respectively. For each age group, both Norwegian men and women had greater cardiorespiratory fitness than cohorts in the United States and Brazil. CONCLUSION: To our knowledge, our analysis represents the largest reference data for cardiorespiratory fitness based on treadmill cardiopulmonary exercise testing. Our findings provide reference values of maximal oxygen uptake measurements from treadmill tests in Brazilian populations that are more accurate than previous standard values based on workload-derived estimations. This data may also add information to the global data used for the interpretation of cardiorespiratory fitness.

RESUMO

INTRODUCTION: Vasculitis entails heterogeneous origins; it starts with an inflammatory process that leads to small vessels' necrosis, hemorrhage, and ischemic lesion, and may further result in occlusion of the vascular lumen. Vasculitis' contribution to allograft rejection is still unclear. This study aims to investigate the incidence of vasculitis in the early stages of heart transplantation as well as to assess the intragraft genes' expression associated with vascular function and subsequently to verify the way in which it affects the outcome of the allograft. METHODS: In this retrospective study, 300 archive paraffin-embedded endomyocardial biopsies from 63 heart allograft recipients were assessed. Cellular rejection and vasculitis were diagnosed through histological analysis, and antibody-mediated rejection was performed with immunohistochemical C4d staining. The transcripts of ICAM, VCAM, VEGF, CCL2, IFNG, TGFB, TNF, ADIPOR1, and ADIPOR2 genes were examined through quantitative polymerase chain reaction using B2M for normalization. RESULTS: We observed a higher prevalence of severe vasculitis in the early period of post-transplant, and recovery was observed to take place around 1 year post-transplant. Additionally, vasculitis was found to be directly associated with acute cellular rejection and antibody-mediated rejection. The intense C4d capillary positivity predicts higher long-term cardiovascular disease mortality. In comparison with the vasculitis-free group, the group with severe vasculitis displayed reduced left ventricular ejection fraction and an upregulation of VCAM and IFNG associated with the downregulation of VEGF, ADIPOR1, and ADIPOR2. CONCLUSION: The vasculitis associated with the presence of C4d and the change in intragraft gene expression profile may contribute to poor allograft outcomes.

RESUMO

BACKGROUND: Inspiratory and peripheral muscle training improves muscle strength, exercise tolerance, and quality of life in patients with chronic heart failure (HF). However, studies investigating different workloads for these exercise modalities are still lacking. OBJECTIVE: To examine the effects of low and moderate intensities on muscle strength, functional capacity, and quality of life. DESIGN: A randomized controlled trial. METHODS: Thirty-five patients with stable HF (aged >18 years, NYHA II/III, LVEF <40%) were randomized to: non-exercise control group (n = 9), low-intensity training group (LIPRT, n = 13, 15% maximal inspiratory workload, and 0.5 kg of peripheral muscle workload) or moderate-intensity training group (MIPRT, n = 13, 30% maximal inspiratory workload and 50% of one maximum repetition of peripheral muscle workload). The outcomes were: respiratory and peripheral muscle strength, pulmonary function, exercise tolerance by the 6-minute walk test, symptoms based on the NYHA functional class, and quality of life using the Minnesota Living with Heart Failure Questionnaire. RESULTS: All groups showed similar quality-of-life improvements. Low and moderate intensities training programs improved inspiratory muscle strength, peripheral muscle strength, and walking distance. However, only moderate intensity improved expiratory muscle strength and NYHA functional class in HF patients. CONCLUSIONS: The low-intensity inspiratory and peripheral resistance muscle training improved inspiratory and peripheral muscle strength and walking distance, demonstrating that LIPRT is an efficient rehabilitation method for debilitated HF patients. In addition, the moderate-intensity resistance training also improved expiratory muscle strength and NYHA functional class in HF patients.

RESUMO

Left ventricular noncompaction is a rare congenital anomaly characterized by excessive left ventricular trabeculation, deep intertrabecular recesses and a thin compacted layer due to the arrest of compaction of myocardial fibers during embryonic development. We report the case of a young patient with isolated left ventricular noncompaction, leading to refractory heart failure that required extracorporeal membrane oxygenation followed by emergency heart transplantation.
