ABSTRACT
Abstract Background: People with haemophilia (PwH) are living longer. Therefore, they can develop atherosclerotic cardiovascular disease (ASCVD). Electrocardiogram (ECG) alterations may be a sign of initial ASCVD before the occurrence of symptoms. Objective: To describe the prevalence of resting ECG alterations among PwH adults asymptomatic for ASCVD. Methods: PwH aged ≥ 30 years without previous ASCVD events were considered for the analysis. Resting ECG traces were analysed according to international reference values and the Brazilian Longitudinal Adult Health Study (ELSA-Brasil) results for asymptomatic Brazilian men. Based on the established normal values and using the QT index, we further described the altered ECGs as minor or major changes, according to the Minnesota Code. Differences between prevalences were evaluated by Pearson's χ2 test. Differences between medians were evaluated by the Mann-Whitney U test. A p-value < 0.05 was accepted as statistically significant. Results: A total of 64 PwH were included in the study. Median age was 44 years (interquartile range 35-52). Most patients had haemophilia A (81%) and 47% were severe. The prevalence of obesity, systemic arterial hypertension (SAH), diabetes mellitus (DM), and dyslipidaemia were 16%, 56%, 14%, and 72%, respectively. All the PwH had sinus rhythm, except for one, who had an implanted pacemaker due to idiopathic third-degree atrioventricular block. Altered ECGs were found in 25% and 30% of PwH, according to established criteria and ELSA-Brasil criteria, respectively. Major changes were found in eight (13%) PwH according to the Minnesota Code, including two ECGs with ischaemia-like wall inactivity. Conclusions: The prevalence of altered ECG varied from 25% to 30% among asymptomatic PwH.
ABSTRACT
Resumo Fundamento A taxa de mortalidade de pessoas com hemofilia (PCH) no Brasil está diminuindo, mas a incidência relativa de mortes associadas a doenças cardiovasculares (DCV) tem aumentado. Objetivos Nosso objetivo foi descrever o escore de risco de DCV de PCHs de acordo com a ferramenta Pooled Cohort Equations Risk (PCER) Calculator e suas recomendações de tratamento. Além disso, foram comparadas as estimativas da PCER com o respectivo escore de risco de Framingham (FRS). Métodos Este estudo transversal incluiu PCHs do sexo masculino, com idade igual ou superior a 40 anos, tratados no Centro de Tratamento Integral de Hemofilia de Pernambuco (Recife/Brasil). PCHs com um evento cardiovascular prévio ou colesterol lipídico de baixa densidade ≥ 5,0 mmol/L foram excluídas. Entrevistas, revisões de prontuários médicos e exames de sangue foram realizados. A ferramenta PCER foi utilizada para estimar o risco de DCV e compará-lo com o respectivo FRS. Um valor de p < 0,05 foi aceito como estatisticamente significativo. Resultados Trinta PCHs foram incluídas. A idade mediana foi de 51,5 [intervalo interquartil-IIQ; 46,0-59,5] anos. A prevalência de obesidade, hipertensão arterial sistêmica, diabetes mellitus, hipertrigliceridemia, hipercolesterolemia e hipoHDLemia foi de 20%, 67%, 24%, 14%, 47% e 23%, respectivamente. O escore mediano da PCER foi de 6,9% [IIQ; 3,1-13,2], com 50% de alto risco (PCER ≥ 7,5%). O uso de estatina foi sugerido para 54% das PCHs. A pressão arterial estava mal controlada em 47% das PCHs. A concordância entre PCER e FRS foi de 80% (κ = 0,60; p = 0,001). Conclusões Metade dos homens com hemofilia, com 40 anos de idade ou mais, teve um alto risco de desenvolver DCV em 10 anos, com fortes recomendações para melhorar o controle da dislipidemia e da pressão arterial.
Abstract Background The mortality rate of Brazilian people with haemophilia (PwH) is decreasing, but the relative incidence of deaths associated with cardiovascular disease (CVD) is increasing. Objectives We aimed to describe the CVD risk score of PwH according to Pooled Cohort Equations Risk (PCER) Calculator tool and its treatment recommendations. We also compared the PCER estimates with the respective Framingham Risk Score (FRS). Methods This cross-sectional study included male PwH ≥ 40 years treated at the Comprehensive Haemophilia Treatment Centre of Pernambuco (Recife/Brazil). PwH with a previous CVD event or a low-density lipid cholesterol ≥ 5.0 mmol/L were excluded. Interviews, medical file reviews, and blood tests were performed. The PCER tool was used to estimate the CVD risk and compare it with the respective FRS. A p-value < 0.05 was accepted as statistically significant. Results Thirty PwH were included. Median age was 51.5 [interquartile range-IQR; 46.0-59.5] years. The prevalence of obesity, systemic arterial hypertension, diabetes mellitus, hypertriglyceridaemia, hypercholesterolaemia, and hypoHDLaemia were 20%, 67%, 24%, 14%, 47%, and 23%, respectively. The median PCER score was 6.9% [IQR; 3.1-13.2], with 50% having a high risk (PCER ≥ 7.5%). Statin use was suggested for 54% of PwH. Blood pressure was poorly controlled in 47% of PwH. The agreement between PCER and FRS was 80% (κ = 0.60; p = 0.001). Conclusions Half of the male people with haemophilia aged 40 years or older had a 10-year high risk of developing CVD with strong recommendations to improve control of dyslipidaemia and blood pressure.
ABSTRACT
RESUMO Objetivo: construir e validar um instrumento de consulta de enfermagem para pessoas com hemofilia. Método: estudo metodológico realizado de fevereiro de 2017 a fevereiro de 2018, em um serviço referência de hematologia do Nordeste do Brasil. Utilizou-se a técnica Delphi para validação, por três grupos de enfermeiras juízas (n=29): Especialistas em hemofilia (n=nove) de nove hemocentros do país; Residência em Hematologia (n=oito); Enfermeiras do Serviço (n=12). A concordância entre as juízas foi verificada por escala Likert e teste exato de Fisher. Resultados: 89,6% não apresentaram dificuldade para compreender o instrumento. Quanto ao grau de relevância, as características 'credibilidade' e 'cientificidade' apresentaram maiores percentuais de extremamente relevante (90%). O teste exato de Fisher foi significativo no grau de satisfação de 'clareza das afirmações' (p<0,05). Conclusão: o instrumento foi considerado válido, proporcionando autonomia, apoio técnico e respaldo ético ao enfermeiro, contribuindo na melhoria da qualidade da assistência.

ABSTRACT Objective: to construct and validate a nursing consultation instrument for people with hemophilia. Method: methodological study conducted from February 2017 to February 2018, in a hematology reference service in Northeast Brazil. The Delphi technique was used for validation, by three groups of nurse judges (n=29): hemophilia specialists (n=nine) from nine blood centers in the country; Hematology Residency (n=eight); Service Nurses (n=12). Inter-rater agreement was checked by Likert scale and Fisher's exact test. Results: 89.6% had no difficulty in understanding the instrument. As for the degree of relevance, the characteristics 'credibility' and 'scientificity' showed higher percentages of extremely relevant (90%). Fisher's exact test was significant in the degree of satisfaction of 'clarity of statements' (p<0.05). Conclusion: the instrument was considered valid, providing autonomy, technical support, and ethical support to the nurse, contributing to the improvement of the quality of care.
