Switch from calcineurin inhibitors to sirolimus-induced renal recovery in heart transplant recipients in the midterm follow-up.

BACKGROUND: Calcineurin inhibitor (CI)-based immunosuppression has prolonged the survival of heart transplant recipients. However, CI-induced renal injury remains as a major problem in these patients. Sirolimus is an immunosuppressant with no significant impact on renal function. A limited number of recent papers have showed that the switch from CI to sirolimus improved renal function in late follow-up of heart transplant patients with CI-related nephrotoxicity. METHODS: Ten heart transplant recipients with CI-induced nephrotoxicity (creatinine 3.9+/-1.8 mg/dl) at a median of 701 (465 to 1325) days posttransplant had CI switched to sirolimus (target though levels 10 to 14 ng/ml) while mycophenolate mofetil (MMF, 3g/day) was maintained and adjusted according to white blood cell count. RESULTS: This maneuver caused a marked decrease in serum creatinine (P<0.00001) at 30 (1.2+/-0.4 mg/dl), 90 (1.3+/-0.4 mg/dl) and 180 (1.3+/-0.4 mg/dl) days post-conversion and a significant decrease in serum potassium levels (5.1+/-0.5 at baseline vs. 3.9+/-0.3 at 180 days, P<0.00005). After the drugs switch no changes in hemoglobin levels, white blood cell count, platelets count, blood glucose and glutamic oxaloacetic transaminase plasma levels were observed. Total cholesterol increased from 242+/-28 to 290+/-117 mg/dl (P>0.05) after 90 days and decreased to 216+/-58 mg/dl at day 180 (P>0.05) after statins dose adjustment. Rejection and infection rates were not modified by sirolimus. CONCLUSIONS: Conversion to a sirolimus-based immunosuppression regimen associated with MMF allowed striking renal function recovery in heart transplant recipients with calcineurin inhibitor-induced renal impairment at midterm follow-up.

Angina-like chest pain and syncope as the clinical presentation of left ventricular endomyocardial fibrosis: a case report.

A 47-year-old woman complained of angina-like chest pain, near-syncope, and syncopal episodes of 17 years' duration. Physical examination was unremarkable. A 12-lead resting ECG showed symmetrically inverted T waves in the inferior and anterolateral leads. A graded treadmill exercise stress test precipitated angina-like chest pain accompanied by a near-syncopal episode associated with a systemic arterial pressure of 60/40 mm Hg. Echocardiography disclosed left ventricular apical obliteration. Left ventriculogram showed a typical "ace of heart'' shadow as well as filling defects and apical obliteration. Endomyocardial biopsy of the left ventricle diagnosed left ventricular endomyocardial fibrosis. Thus, angina-like chest pain and near-syncopal episodes should be added to the list of clinical manifestations of pure left ventricular endomyocardial fibrosis.

Trypanosoma cruzi myocardial infection reactivation presenting as complete atrioventricular block in a Chagas' heart transplant recipient.

A 56-year-old man underwent orthotopic heart transplantation because of end-stage Chagas' cardiomyopathy. One hundred and ten days following heart transplantation, an electrocardiogram tracing showed complete atrioventricular block, which was treated with temporary transvenous pacemaker insertion. An underlying endomyocardial biopsy was graded 3A. The patient was treated with pulse steroid therapy. One week later, the patient died of multiorgan failure secondary to septicemia. A careful review of the endomyocardial biopsy showed nests of parasites in the myocardial tissue accompanied by mononuclear cell infiltrate similar to that found in acute graft rejection. Thus, complete atrioventricular block may be another clinical manifestation of Trypanosoma cruzi infection reactivation in Chagas' heart transplant recipients.

Psychological assessment of patients undergoing cardiac transplant in a teaching hospital (2004 to 2012).

OBJECTIVE: To analyze the psychological evaluations of patients with heart failure waiting for heart transplantation. METHODS: The data were obtained from patient records containing pre-surgery psychological evaluations performed by psychologists from the multidisciplinary cardiology team. The evaluation protocol included the Quality of Life Questionnaire (SF-36), Beck Depression Inventory, and an interview script. RESULTS: The results of psychological evaluations performed between 2004 and 2012 for 60 candidates for heart transplantation were analyzed: 43 men and 17 women aged between 16 and 66 years (Mean=45.18; SD=11.91), predominantly from the São José do Rio Preto area (São Paulo state, Brazil) (83%), with incomplete elementary education (68%), and who were in stable relationships (73%). Although women presented higher mean scores for depression (21.41) than men (14.61), there was no significant difference between genders. Women's quality of life was impaired in all domains compared to men (below 50%) and was significantly poorer in the physical functioning (P=0.01), vitality (P=0.00), emotional role functioning (P=0.04), and mental health (P=0.02) domains. CONCLUSION: Patients with psychosocial vulnerability (e.g., depression) identified before transplantation should receive psychological treatment.

Prognostic impact of Chagas' disease in patients awaiting heart transplantation.

BACKGROUND: The role of Chagas' etiology of chronic heart failure in predicting patient outcomes while awaiting heart transplantation is unknown. Accordingly, in this study we compare outcomes in Chagas' disease with non-Chagas'-disease-related advanced heart failure among patients on the waiting list for heart transplantation. METHODS: We reviewed the clinical outcomes of 103 consecutive patients with chronic heart failure listed for heart transplantation from August 2000 to January 2008 at a single institution. Forty-six (44%) patients were diagnosed with Chagas' disease on the basis of positive serology. A Cox proportional hazards model was used to establish independent predictors of mortality, whereas competing risk analysis was used to estimate time-related prevalence of death and heart transplantation in Chagas' disease and non-Chagas' disease patients. RESULTS: In the multivariate model, inotropic support (p < 0.0005; hazard ratio = 5.96; 95% confidence interval [CI] 2.41 to 14.71) and Chagas' disease etiology of heart failure (p = 0.02; hazard ratio = 2.27; 95% CI 1.14 to 4.52) were retained as independent predictors of mortality. Prevalence of death at 100 days after listing was 30% in Chagas' disease and 16% in non-Chagas' disease patients (p = 0.02), despite no difference in the competing rates of transplantation (30% in Chagas' and 37% in non-Chagas' patients, p = 0.5). CONCLUSIONS: Chagas' disease etiology serves as an independent predictor of mortality in patients listed for heart transplantation, with a worse outcome when compared with non-Chagas' disease patients.

Objetivo: Analisar protocolos de avaliação psicológica de pacientes portadores de insuficiência cardíaca, candidatos a transplante cardíaco. Métodos: Os dados da avaliação foram obtidos junto ao arquivo de avaliações psicológicas realizadas pré-cirurgia pelos psicólogos que integram a equipe multidisciplinar de Cardiologia. O protocolo de avaliação inclui o Questionário de Qualidade de Vida - SF-36 o Inventário Beck de Depressão e um roteiro de entrevista. Resultados: Foram analisados os resultados das avaliações psicológicas de 60 pacientes candidatos a transplante cardíaco no período entre 2004 e 2012: 43 homens e 17 mulheres, com idade entre 16 e 66 anos (M=45,18 dp=11,91), 83% provenientes da região, com ensino fundamental incompleto (68%) e união estável (73%). Embora as mulheres tenham apresentado escores mais altos para depressão (21,41) em relação aos homens (14,61), não houve diferença significante entre os gêneros. A qualidade de vida das mulheres mostrou-se prejudicada em todos os domínios (abaixo de 50%) e esse prejuízo foi significantemente inferior aos homens na capacidade funcional (P=0,01), vitalidade (P=0,00), aspectos emocionais (P=0,04) e saúde mental (P=0,02). Conclusão: Pacientes com vulnerabilidades psicossociais identificadas no pré-transplante (ex. depressão) devem receber atendimento psicológico. .

Angina estável: apresentação e classificação / Stable angina: clinical manifestation

A doença aterosclerótica coronária é a principal causa de mortalidade na maioria dos países industrializados. Estima-se que 12.900.000 indivíduos nos Estados Unidos apresentem doença obstrutiva coronária, dos quais 6.600.000 têm angina e 7.200.000 têm infarto do miocárdio. No Brasil, no ano de 2000, 27,5% dos óbitos foram decorrentes de doença cardiovascular, com 30% desses óbitos sendo atribuídos à doença isquêmica do coração. Em decorrência da gravidade do problema e do aumento da prevalência da doença, como resultado do aumento da expectativa de vida da população, o reconhecimento, a estratificação de risco e o tratamento corretos são de extrema importância para a melhoria das condições dessa situação que hoje se tornou um problema de saúde pública. Em face das múltiplas formas de apresentação e dos graus de gravidade da doença, a cuidadosa coleta da história clínica com correta caracterização da dor e estimativa dos fatores de risco para doença aterosclerótica coronária são fundamentais para o diagnóstico correto. Além disso, a correlação desses dados com idade e sexo nos permite a correta classificação e a correta estratificação do risco da doença e, por conseguinte, a escolha adequada dos testes laboratoriais necessários e do tratamento a ser instituído.
