Electrocardiography scar quantification correlates with scar size of hypertrophic cardiomyopathy seen by multidetector computed tomography.

BACKGROUND: Hypertrophic cardiomyopathy (HCM), a genetically transmitted disease, is the most common genetic cardiovascular disease. Current strategies to stratify risk are expensive and concentrated in wealthy centers. Twelve-lead electrocardiography (ECG) is inexpensive, universally available, and can be readily used for Selvester QRS scoring, which estimates scar size. This study aimed to establish the relation between ECG scar quantification and myocardial fibrosis (extent of myocardial delayed enhancement) in multidetector computed tomography (MDCT). HYPOTHESIS: There is a significant association between ECG scar quantification and the extent of myocardial delayed enhancement in MDCT. METHODS: Seventy-five patients with HCM underwent a routine clinical evaluation and echocardiography, 12-lead ECG, and MDCT study. Patients with and without an implantable cardioverter-defibrillator were included. RESULTS: The estimated Selvester QRS score of myocardial fibrosis was correlated significantly (R = 0.70; P < 0.01) with the quantified MDCT fibrosis. Compared with MDCT, the QRS score had 84.8% sensitivity and 88.8% specificity. Myocardial fibrosis was present in 88% of these patients with HCM (fibrotic mass, 9.87 ±10.8 g) comprising 5.66% ±6.16% of the total myocardial mass seen on the MDCT images. The Selvester QRS score reliably predicted the fibrotic mass in 76% of patients, which estimated 8.44% ±7.39% of the total myocardial mass. CONCLUSIONS: The Selvester QRS score provides reliable quantification of myocardial fibrosis and was well correlated with MDCT in patients with HCM.

Clinical Course of Patients Undergoing Myocardial Revascularization Surgery in a Public Cardiology Referral Hospital in Pará, Brazil

Myocardial revascularization surgery (MRS) is the most frequently performed cardiac surgery in Brazil. However, data on mortality rates among patients undergoing MRS in hospitals other than the main referral centers in the northern Brazil are scarce. Objective: To describe the clinical course of patients that submitted to MRS in the major public cardiology referral hospital in the Brazilian Amazon. Methods: Retrospective cohort analysis, by review of medical records of patients who had undergone MRS at Hospital das Clínicas Gaspar Vianna (FHCGV) from January 2013 to June 2014. Results: A total of 179 patients were evaluated. Mortality rate was 11.7% until 30 days after surgery. Waiting time for surgery ≥ 30 days (OR 2.59, 95%CI 1.02 - 6.56, p = 0.039), infection during hospitalization (OR 3.28, 95%CI 1.15 - 9.39, p = 0.021) and need for hemodialysis after surgery (OR 9.06 95%CI 2.07 - 39.54, p = 0.001) were predictors of mortality after CABG. Conclusion: A high mortality rate in the study population was found, higher than that reported in the literature and in other regions of Brazil

[Quality of life of hemodialysis patients in a Brazilian Public Hospital in Belém - Pará].

INTRODUCTION: End-stage chronic kidney disease (CKD) requiring dialysis affects the quality of life sometimes more severely than other chronic diseases, such as rheumatoid arthritis, heart failure, coronary artery disease, and chronic obstructive pulmonary disease, exerting a negative effect on the energy and vitality levels, limiting social interactions, and hindering psychic health. OBJECTIVE: To evaluate the quality of life of patients with CKD on hemodialysis in a public Brazilian Amazonian hospital. METHODS: Data were collected through interview based on the Brazilian version of the SF-36 questionnaire. The study was conducted on 50 patients (mean age, 48 ± 16 years; mean hemodialysis time, 3 ± 2.9 years). RESULTS: The most affected domain was role limitations due to physical health, with a mean score of 36 ± 36, and 58% of the patients in the lowest quartile, while mental health and social functioning were relatively preserved, with most patients in the highest quartile. Men obtained poorer scores than women did for role limitations due to physical health and vitality. Age correlated negatively with physical functioning. Patients on hemodialysis for more than one year had better scores in the social functioning domain, with a positive correlation between dialysis time and physical functioning. CONCLUSIONS: The domains assessed were globally impaired in the population studied, especially regarding role limitations due to physical health, suggesting that chronic disease with prolonged treatment has a negative influence on those domains.

Artéria Coronária Direita Originada da Artéria Descendente Anterior: Uma Rara Anomalia Coronariana / Anomalous Origin of the Right Coronary Artery from the Mid-Left Anterior Descending Artery: A Rare Coronary Anomaly

A artéria coronária única é anomalia rara, que pode estar associada à isquemia miocárdica e morte súbita. Apresentamos o caso de uma mulher jovem, com quadro de angina atípica, cujo cateterismo revelou artéria coronária direita que se originava do terço médio da artéria descendente anterior, uma variante da artéria coronária única.

A single coronary artery is a rare anomaly that may be associated with myocardial ischemia and sudden death. We present a case of a young woman with atypical angina whose coronary angiography revealed a right coronary artery originating from the mid left anterior descending artery, a variant of the single coronary artery.

Qualidade de vida de pacientes em hemodiálise em um hospital público de Belém - Pará / Quality of life of hemodialysis patients in a Brazilian Amazonian public hospital

Introdução: A doença renal crônica (DRC) dialítica afeta a qualidade de vida do paciente, por vezes de maneira mais intensa que outras doenças crônicas, como artrite reumatóide, insuficiência cardíaca, doença arterial coronariana e doença pulmonar obstrutiva crônica, exercendo efeito negativo sobre os níveis de energia e vitalidade, limitando as interações sociais e prejudicando a saúde psíquica. Objetivo: Avaliar a qualidade de vida de pacientes com IRC em programa de hemodiálise ambulatorial em um hospital público de Belém - Pará. Método: O estudo baseou-se em dados coletados em entrevista, utilizando a versão brasileira do questionário SF-36. Foram avaliados 50 pacientes, com idade média de 48 +- 16 anos e tempo médio em hemodiálise de 3 +- 2,9 anos, 62% do sexo masculino. Resultados: A dimensão mais afetada foi relativa aos aspectos físicos, com pontuação média de 36 +- 36 e 58% dos pacientes no quartil mais baixo, enquanto saúde mental e aspectos sociais demonstraram relativa preservação, com a maioria dos pacientes alocados no quartil mais elevado. A população masculina apresentou piores escores que a feminina quanto a aspectos fpisicos e vitalidade. A idade correlacionou-se negativamente com a capacidade funcional. Os pacientes em hemodiálise há mais de um ano apresentam melhores níveis no domínio aspectos sociais e houve correlação positiva entre o tempo em diálise e a capacidade funcional. Conclusão: os domínios analisados estiveram globalmente comprometidos na população estudada, em especial com relação aos aspectos físicos, sugerindo a influência negativa da presença de doença crônica, com tratamento prolongado sobre esses âmbitos.

Introduction: Chronic kidney disease (CKD) affects the quality of dialysis patient's life, sometimes more intensely than other chronic diseases such as rheumatoid arthritis, heart failure, coronary artery disease and chronic obstructive pulmonary disease, exerting a negative effect on energy levels and vitality, limiting social interactions and impairing mental health. Objective: To evaluate the quality of life of patients with CRF on hemodialysis outpatients in a public hospital in Belém - Pará Method: The study was based on data collected in interviews, using the Brazilian version of SF-36. We evaluated 50 patients, mean age 48 + - 16 years and average time on hemodialysis 3 + - 2.9 years, 62% male. Results: The most affected dimension was related to physical aspects, with an average score of 36 + - 36 and 58% of patients in the lowest quartile, while mental health and social aspects demonstrated relative preservation, with the majority of patients allocated in the highest quartile . The male population had worse scores than the female respects fpisicos and vitality. The age was negatively correlated with functional capacity. Patients on dialysis for more than a year have the best levels in the areas social and positive correlation between time on dialysis and functional capacity. Conclusion: The areas examined were broadly committed to this population, especially in relation to the physical aspects, suggesting the negative influence of the presence of chronic disease, with prolonged treatment on these fronts.
