Health, sleep and lack of time: relations to domestic and paid work in nurses

OBJECTIVE: To assess whether reported morbidity and complaints of lack of time and sleep are associated with the burden of professional work and housework among nurses. METHODS: A cross-sectional exploratory study was carried out among female nurses and nurse assistants (N=206) of a public hospital in Rio de Janeiro, Brazil. Data were collected by means of a questionnaire. The prevalence ratio and 95% confidence intervals were estimated. RESULTS: Mean duration of professional work and housework time was 40.4 and 31.6 hours/week, respectively. Long professional working time (over 44 hours/week) were associated with mild emotional disorders (PR=1.37; 95% CI: 1.05-1.80), complaints of lack of time for resting/leisure (PR=1.61; 95% CI: 1.31-1.97), housework (PR=1.48; 95% CI: 1.12-1.97), and childcare (PR=1.99; 95% CI: 1.51-2.63). Long housework time (over 28 hours/week) was associated with lower prevalence of lack of time for childcare (PR=0.62; 95% CI: 0.46-0.84). High housework load was associated with lack of personal time and complaints of varicose veins (PR=1.31; 95% CI: 1.14-1.50 and PR=1.31; 95% CI: 1.08-1.58, respectively). Complaints of varicose veins were also frequent among female nurses with a total work load above 84 hours (PR=1.30; 95% CI: 1.05-1.61), though this group has shown a lower prevalence of arterial hypertension and recurrent headaches (PR=0.35; 95% CI: 0.15-0.83 and PR=0.53; 95% CI: 0.32-0.89, respectively). CONCLUSIONS: Results suggest that both professional and home environments are relevant in the evaluation of work overload on nurses' health and their family and social life. It is stressed the need for instruments for analyzing total workload among female populations.

Avaliação da aptidão física funcional de idosos hipertensos da Cidade da Praia, Cabo Verde: estudo piloto

Introdução – A avaliação da aptidão física permite a identificação de níveis de incapacidade e risco de perda funcional, pelo que é extremamente útil na estruturação de programas de atividade física específicos, que constituem a primeira intervenção no que toca à intervenção não-farmacológica na Hipertensão Arterial Sistémica (HAS). Objetivo – Avaliar a aptidão física funcional e os níveis de atividade física de idosos hipertensos da Cidade da Praia – Cabo Verde. Metodologia – A flexibilidade, força e resistência muscular, resistência aeróbia e composição corporal foram avaliadas através da bateria de Fullerton e dinamometria isométrica manual. O nível de atividade física foi avaliado pelo questionário Seven Day Physical Activity Recall (7D-PAR). Resultados – Participaram 75 idosos, com idades compreendidas entre os 60 e os 99 anos, 68% dos quais eram mulheres, com índice de massa corporal (IMC) de 25,2±5,4, com diagnóstico clínico de HAS. O tempo despendido em atividades de intensidade moderada encontrava-se dentro dos valores recomendados, embora a atividade intensa se encontrasse muito abaixo do recomendado e não efetuassem qualquer exercício de força e flexibilidade. A resistência aeróbia expressa pelo Teste 6 Minutos de Marcha (T6MM) apresentou valores médios baixos (293,5±112,2m), bem como a flexibilidade e a força de preensão. Esta associação é um indicador de baixa capacidade funcional. Conclusão – Os baixos níveis de aptidão física apresentados, associados a baixos níveis de atividade física indiciam baixa capacidade funcional e justificam a necessidade urgente da inserção de programas de atividade física nesta população.

Hospitalizations for ambulatory care-sensitive conditions, Minas Gerais, Southeastern Brazil, 2000 and 2010

OBJECTIVE To analyze hospitalization rates and the proportion of deaths due to ambulatory care-sensitive hospitalizations and to characterize them according to coverage by the Family Health Strategy, a primary health care guidance program. METHODS An ecological study comprising 853 municipalities in the state of Minas Gerais, under the purview of 28 regional health care units, was conducted. We used data from the Hospital Information System of the Brazilian Unified Health System. Ambulatory care-sensitive hospitalizations in 2000 and 2010 were compared. Population data were obtained from the demographic censuses. RESULTS The number of ambulatory care-sensitive hospitalizations declined from 20.75/1,000 inhabitants [standard deviation (SD) = 10.42) in 2000 to 14.92/thousand inhabitants (SD = 10.04) in 2010 Heart failure was the most frequent cause in both years. Hospitalizations rates for hypertension, asthma, and diabetes mellitus, decreased, whereas those for angina pectoris, prenatal and birth disorders, kidney and urinary tract infections, and other acute infections increased. Hospitalization durations and the proportion of deaths due to ambulatory care-sensitive hospitalizations increased significantly. CONCLUSIONS Mean hospitalization rates for sensitive conditions were significantly lower in 2010 than in 2000, but no correlation was found with regard to the expansion of the population coverage of the Family Health Strategy. Hospitalization rates and proportion of deaths were different between the various health care regions in the years evaluated, indicating a need to prioritize the primary health care with high efficiency and quality.

Efeito hipotensivo de uma sessão de exercício aeróbio em idosos hipertensos

Introdução: As doenças cardiovasculares, entre elas, a hipertensão arterial constituem um dos problemas de saúde de maior prevalência, principalmente na população idosa. Alguns estudos têm apontado o exercício físico aeróbio como uma medida não farmacológica, eficaz, para a prevenção/controlo da hipertensão arterial. Objetivo: Este estudo avaliou o efeito agudo hipotensivo de uma sessão isolada de exercício físico aeróbio num grupo de idosos hipertensos. Metodologia: A amostra foi composta por 20 idosos, de ambos os géneros, hipertensos, pertencentes a três centros de convívio distintos. Os indivíduos foram divididos aleatoriamente em dois grupos, o grupo que fez a sessão de exercício (n=10, idade 81,2 ± 4,71 anos) e o grupo de controlo (n=10, idade 81,2 ± 3,12 anos). O grupo de exercício participou numa sessão de exercício físico aeróbio que teve 35 minutos de duração, sendo constituída por 5 minutos de aquecimento seguidos por duas frações de marcha a uma intensidade de 40-60% da frequência cardíaca (FC) de reserva, cada uma delas com a duração de 10 minutos, separadas por um intervalo de recuperação de 5 minutos, terminando com 5 minutos de retorno à calma. O grupo controlo permaneceu 35 minutos em repouso sentado. Todos indivíduos foram sujeitos à avaliação da pressão arterial (PA) e FC, antes, no intervalo, no término, 20 e 40 minutos após a sessão de exercício/35 minutos de repouso. Resultados: Observou-se que no grupo que fez o exercício físico a PA sistólica medida aos 40 minutos (123,04 ± 23,07 mmHg) após a sessão de exercício foi significativamente inferior aos restantes momentos de avaliação, incluindo o valor observado em repouso (135,57 ± 19,43 mmHg). A PA diastólica medida também aos 40 minutos (61,94 ± 7,49 mmHg) após a sessão foi inferior à obtida ao intervalo da sessão (72,40 ± 8,51 mmHg). A FC foi significativamente superior ao intervalo e no término da sessão comparativamente a todos os outros momentos de avaliação. Quanto ao grupo controlo não se verificaram diferenças significativas em nenhum dos parâmetros avaliados. Conclusão: Uma sessão isolada de exercício aeróbio de curta promove a ocorrência do fenómeno hipotensão pós-exercício em idosos hipertensos.

Doenças Raras e Medicamentos Órfãos em Portugal: Impacto Económico dos Medicamentos Órfãos na Região da Beira Interior

Medicamentos órfãos destinam-se ao diagnóstico, prevenção ou tratamento de doenças muito graves ou que causem risco de vida, que são raras e não afetam mais do que 5 em cada 10.000 pessoas na União Europeia. Estes medicamentos são apelidados de órfãos, já que em condições normais de mercado, não existe interesse para as empresas farmacêuticas desenvolver tais medicamentos, devido ao baixo retorno financeiro causado pela raridade. O objetivo deste trabalho consiste em avaliar a utilização de medicamentos órfãos em Portugal e analisar o impacto económico destes medicamentos na região da Beira Interior. Os dados recolhidos permitiram avaliar retrospetivamente o consumo de medicamentos no período de janeiro a dezembro de 2013 em Portugal e em particular nos hospitais: Centro Hospitalar Cova da Beira, Unidade Local de Saúde da Guarda e Unidade Local de Saúde de Castelo Branco. A informação dos dados refere-se ao consumo dos Hospitais e Instituições do Serviço Nacional de Saúde, reportada mensalmente ao INFARMED (Autoridade Nacional do Medicamento e Produtos de Saúde, I.P.). Foram identificados 48 medicamentos órfãos com Autorização de Introdução no Mercado na Europa, 47 são medicamentos com Autorização de Introdução no Mercado português, sendo a Mercaptopurina o único medicamento órfão que necessita de Autorização de Utilização Especial. O Tafamidis foi o medicamento que envolveu maior custo económico a nível nacional no tratamento destas doenças. O valor total de consumo no Centro Hospitalar Cova da Beira é de 11% em relação ao consumo total de medicamentos nesta unidade. As doenças Lisossomais são o grupo mais representativo, do qual faz parte a doença de Pompe. No entanto, a doença com uma prevalência mais elevada é a Hipertensão Arterial Pulmonar. Esta e as doenças oncológicas são as doenças comuns nas três unidades hospitalares. Na Unidade Local de Saúde da Guarda a doença com maior consumo de medicamentos órfãos é a Hipertensão Arterial Pulmonar e na Unidade Local de Saúde de Castelo Branco são as doenças oncológicas. O valor acumulado de medicamentos órfãos na região da Beira Interior no ano de 2013 representa1% do valor global de consumo destes medicamentos em Portugal. A representatividade de consumo destes medicamentos em Portugal em relação ao consumo total de medicamentos em meio hospitalar é de cerca de 7,7%.Em conclusão, o consumo de medicamentos órfãos é bastante elevado em relação aos restantes medicamentos, tanto na Beira Interior como no resto do país, apesar disso é bastante importante que continuem a existir medidas no sentido de incentivar os fabricantes e melhorar o acesso a estes medicamentos.

A comparative study of severe scorpion envenomation in children caused by Tityus bahiensis and Tityus serrulatus

From January 1984 to May 1994, 17 of 239 children under 15 years old stung by Tityus serrulatus (15.1%) or Tityus bahiensis (84.9%) presented severe envenoming. Of these 17 patients (1-11 years old; median=2 yr) 14 were stung by T.serrulatus and three by T.bahiensis. All of them received scorpion antivenom i.v. at times ranging from 45 min. to 5 h after the accident (median=2h). On admission, the main clinical manifestations and laboratory and electrocardiographic changes were: vomiting (17), diaphoresis (15), tachycardia (14), prostration (10), tachypnea (8), arterial hypertension (7), arterial hypotension (5), tremors (5), hypothermia (4), hyperglycemia (17), leukocytosis (16/16), hypokalemia (13/17), increased CK-MB enzyme activity (>6% of the total CK, 11/12), hyperamylasemia (11/14), sinusal tachycardia (16/17) and a myocardial infarction-like pattern (11/17). Six patients stung by T.serrulatus had depressed left ventricular systolic function assessed by means of echocardiography. Of these, five presented pulmonary edema and four had shock. A child aged two-years old presented severe respiratory failure and died 65 h after being stung by T.serrulatus. Severe envenomations caused by T.serrulatus were 26.2 times more frequent than those caused by T.bahiensis (p<0.001).

Desigualdades socioeconómicas na doença cardiovascular em Portugal : estudo baseado no 4º Inquérito Nacional de Saúde

RESUMO - Em Portugal, as doenças cardiovasculares (DCV), incluindo o acidente vascular cerebral (AVC) e a doença cardíaca isquémica (DCI), são das principais causas de morbi-mortalidade e invalidez. Sabe-se que o nível socioeconómico (NSE) influencia o estado de saúde, todavia são escassas as evidências sobre as desigualdades socioeconómicas na DCV em Portugal. O objectivo deste estudo foi analisar a distribuição da DCV de acordo com o NSE na população portuguesa. Foi realizado um estudo transversal exploratório-descritivo usando a base de dados do 4º Inquérito Nacional de Saúde, 2005/06. As desigualdades socioeconómicas nas DCV, AVC e DCI, factores de risco [sedentarismo, hipertensão arterial (HTA), diabetes mellitus (DM), tabagismo, obesidade e sofrimento psicológico (Mental Health Inventory ≤ 52)] e número de consultas médicas, foram analisadas através dos odds ratio por NSE (rendimento familiar equivalente, escala modificada da OCDE) com intervalo de confiança de 95% e dos índices e curvas de concentração. Dos 21 807 indivíduos, 53,34% são do sexo feminino, a idade média é de 54±11 e entre 35 e 74 anos. A DCV, a DCI, o AVC, a HTA, a DM e a obesidade estão associados com NSE mais baixos, o tabagismo está associado aos NSE mais elevados, enquanto o sedentarismo, o número de consultas médicas e o sofrimento psicológico não apresentam associação significativa com o NSE. Os resultados revelam a associação entre os estilos de vida, morbilidade e NSE e demonstram que são necessárias políticas de saúde mais abrangentes, de acordo com as características individuais, culturais e socioeconómicas e dirigidas à promoção da saúde e prevenção da doença. -------------------------------------------- ABSTRACT - Cardiovascular diseases (CVD), including stroke and ischemic heart disease (IHD), are the leading causes of morbidity, mortality and disability in Portugal. It is known that socioeconomic status (SES) influences health status; however there is little evidence about socioeconomic inequalities in CVD in Portugal. The aim of this study was to analyze the distribution of CVD according to SES in the Portuguese population. We conducted a cross-sectional descriptive exploratory study using the database of the 4th National Survey of Health, 2005/06. Socioeconomic inequalities in CVD, stroke, IHD, risk factors [physical inactivity, arterial hypertension (AHT), diabetes mellitus (DM), smoking, obesity and psychological distress (Mental Health Inventory ≤ 52)], as well as the number of medical visits, were analyzed by SES (family income using the OECD modified equivalent scale) using odds ratio (confidence interval = 95%), and concentration curves and indices. Of the 21 807 individuals, 53.34% are female, aged between 35 and 74 with mean 54 ± 11 years. CVD, IHD, stroke, AHT, MD and obesity are associated with lower SES, smoking is associated with higher SES, while physical inactivity, number of medical visits and psychological distress showed no significant association with SES. Results suggest an association between lifestyle, morbidity and SES. They also demonstrate the need for comprehensive health strategies, involving health promotion and disease prevention, that incorporate individual, cultural and socioeconomic characteristics.

Effects of Acute Autonomic Modulation on Atrial Conduction Delay and Local Electrograms Duration in Paroxysmal Atrial Fibrillation

Slowed atrial conduction may contribute to reentry circuits and vulnerability for atrial fibrillation (AF). The autonomic nervous system (ANS) has modulating effects on electrophysiological properties. However, complex interactions of the ANS with the arrhythmogenic substrate make it difficult to understand the mechanisms underlying induction and maintenance of AF. AIM: To determine the effect of acute ANS modulation in atrial activation times in patients (P) with paroxysmal AF (PAF). METHODS AND RESULTS: 16P (9 men; 59±14years) with PAF, who underwent electrophysiological study before AF ablation, and 15P (7 men; 58±11years) with atrioventricular nodal reentry tachycardia, without documentation or induction of AF (control group). Each group included 7P with arterial hypertension but without underlying structural heart disease. The study was performed while off drugs. Multipolar catheters were placed at the high right atrium (HRA), right atrial appendage (RAA), coronary sinus (CS) and His bundle area (His). At baseline and with HRA pacing (600ms, shortest propagated S2) we measured: i) intra-atrial conduction time (IACT, between RAA and atrial deflection in the distal His), ii) inter-atrial conduction time (interACT, between RAA and distal CS), iii) left atrial activation time (LAAT, between atrial deflection in the distal His and distal CS), iv) bipolar electrogram duration at four atrial sites (RAA, His, proximal and distal CS). In the PAF group, measurements were also determined during handgrip and carotid sinus massage (CSM), and after pharmacological blockade of the ANS (ANSB). AF was induced by HRA programmed stimulation in 56% (self-limited - 6; sustained - 3), 68.8% (self-limited - 6; sustained - 5), and 50% (self-limited - 5; sustained - 3) of the P, in basal, during ANS maneuvers, and after ANSB, respectively (p=NS). IACT, interACT and LAAT significantly lengthened during HRA pacing in both groups (600ms, S2). P with PAF have longer IACT (p<0.05), a higher increase in both IACT, interACT (p<0.01) and electrograms duration (p<0.05) with S2, and more fragmented activity, compared with the control group. Atrial conduction times and electrograms duration were not significantly changed during ANS stimulation. Nevertheless, ANS maneuvers increased heterogeneity of the local electrograms duration. Also, P with sustained AF showed longer interACT and LAAT during CSM. CONCLUSION: Atrial conduction times, electrograms duration and fractionated activity are increased in PAF, suggesting a role for conduction delays in the arrhythmogenic substrate. Acute vagal stimulation is associated with prolonged interACT and LAAT in P with inducible sustained AF and ANS modulation may influence the heterogeneity of atrial electrograms duration.

Vasodilatadores Pulmonares Selectivos na Hipertensão Pulmonar Grave: Utilização de 3 Diferentes Tipos de Endpoint

The therapeutic approach to severe pulmonary arterial hypertension (PAH), whether primary or secondary to connective tissue disorders, thromboembolic phenomena or congenital heart disease with Eisenmenger syndrome, has evolved in recent years following the introduction of selective pulmonary vasodilators, including prostacyclin analogs and endothelin receptor antagonists. AIM: To correlate three different endpoints (6-minute walk test, Tei index and peak tricuspid regurgitation velocity by Doppler echocardiographic study) during follow-up of PAH patients under selective vasodilator therapy. METHODS: Eleven patients (9 female, age 42 +/- 18 years) with severe PAH (> or = 65 mmHg), 64% with Eisenmenger syndrome, in NYHA class > or = II, were assessed during a follow-up of 11 +/- 8 months. Eight patients were already under therapy with iloprost or bosentan. RESULTS: There was no correlation between the three endpoints before and after therapy as assessed by Pearson's correlation coefficient. There was, however, an improvement in all of them after selective vasodilatory therapy. CONCLUSION: Therapeutic response can be accurately measured by the traditional endpoint (6-minute walk test) or by echocardiographic endpoints. However, the lack of correlation between them excludes their use as alternatives in patient follow-up.

Five Cases of Atypical Rickettsial Infections

Background: Rickettsia conorii is the most frequent species of RickettsiaI causing disease in Portugal. In general the disease manifests itself by fever, exanthema, headaches and the presence of an eschar. However atypical forms can be present and physicians should be aware. Aims: Analyse the atypical presentation of rickettsiosis. Material and Methods: Children admitted at the CHLC Hospital from 2000 to 2010 with atypical presentation of rickettsiosis. Clinical diagnosis was confirmed by serology and molecular techniques (PCR). Results: Five cases of children with a median age of 2 years, 1 of which female, were admitted between June and August. The diagnoses were: myositis (1), synovitis (1), cholecystitis (1), orchiepididymitis (1) and meningitis (1). Myositis developped with functional disability, CPK 9600 U/L, lower limbs’ edema, hypoalbuminemia (1,6 g/dL) and arterial hypertension. Synovitis developped with functional disability, synovial fluid increase and CRP 16,2 mg/dL. The child with cholecystitis had abdominal pain, intraabdominal fluid increase, leukopenia (1900/μL), thrombocytopenia (75000/μL) and CRP 15,3 mg/dL. Orchiepididymitis developped with testicle’s inflammatory signs, leukopenia (2900/μL), thrombocytopenia (90000/μL) and CRP 14,45 mg/dL. The patient with meningitis, who had pleocytosis (320 cells/μL), hyperproteinorrachia (284 mg/dL), hypoglicorrachia (36 mg/dL), presented only with fever and headaches. The tache noire and the classical triad were present in 3/5 cases. The clinical course was favourable in all cases. Antibodies against Rickettsia of spotted fever group were detected in 3/5 cases. In one patient Rickettsia conorii Malish strain was identified by PCR and sequencing. Conclusions: Rickettsial infection may present itself unusually. In a country of high prevalence, especially during summer months and in the presence of an inoculation eschar, it is of the uttermost importance to study the atypical presentations for a possible rickettsial infection.

Prognostic Factors in Adult Patients with Idiopathic IgA Nephropathy

Introduction. IgA nephropathy is the dominant primary glomerular disease found throughout the majority of the world’s developed countries. Accurately identifying patients who are at risk of progressive disease is challenging. We aimed to characterise clinical and histological features that predict poor prognosis in adults. Patients and Methods. We performed a single-centre retrospective observational study of biopsy-proven IgA nephropathy. The primary outcome was renal survival and death from any cause, and the secondary outcome was proteinuria remission. Results. Data from 49 cases were available for analysis with a median follow-up of 4 years. There were no deaths. Univariable analyses identified acute renal failure, low estimated glomerular filtration rate for ≥3 months (low eGFR), arterial hypertension, baseline proteinuria, glomerular sclerosis >50% and interstitial fibrosis >50% as poor prognostic markers. Low eGFR persisted significant by multivariable model that used only clinical parameters. Multivariable models with histopathologic parameters observed that tubular atrophy/interstitial fibrosis >50% was independently associated with the primary outcome. Proteinuria remission throughout follow-up had no prognostic value in our revision. Conclusions. Two independent predictors of poor renal survival at time of biopsy were found: low eGFR and tubular atrophy/interstitial fibrosis >50%.

Blood Donation in the Hospital de S. José. A 11-Year Retrospective Analysis of Deferrals and Exclusions

Background: Approximately 5% of the population donates blood each year in developed countries. Recruiting and maintaining a pool of altruistic and healthy blood donors is a challenging task. Blood donation as a dynamic process must naturally co-exist with the arguably essential deferrals. Aims: To analyse a 11-year cohort of donors and blood donations in order to determine the profile of the average donor and the typical donation. Characterize the donor’s population in terms of gender, age, number of donations, most common causes for deferral and exclusion and the possible relationships between them. Establish the tendency flow of donations per year. Methods: Analysis of 95861 blood donations from 31550 donors collected between 2000 and 2010 (11 years) in the Immunohemotherapy Department of the ‘‘Centro Hospitalar Lisboa Central - Hospital de Sa˜o Jose´’’ (Lisboa, Portugal). Prior to blood donation, donors were required to fill out a form of informed consent, a questionnaire of 21 ‘‘yes or no’’ questions and were submitted to a clinical assessment and physical examination including: measurement of weight, blood pressure, pulse and capillary hemoglobin levels. Post-donation, the collected blood was tested for ALT elevation and blood-borne viral agents (HBV, HCV, HIV 1 and 2 and HTLV 1 and 2) and other infections (Treponema pallidum). Blood donors and donations were registered in a database and statistically studied in terms of: gender and age distribution, number of donations, most common causes for deferral and exclusion. The frequency of blood donations throughout the period of observation was analyzed and statistically significant relationships between the collected variables were investigated. Results: From the population of 31550 donors 61% were male and a mean age of 41.5 years (± 12.5 years) was found. From the total of 95682 blood donations collected 78% were successful while the most common causes for deferral were: donation incompatible hemoglobin levels (5% of the blood donations and 22% of deferrals), ALT elevation (3% and 14%), positive blood screening test for Treponema pallidum (1% and 6%), medication (1% and 4%), positive serological blood markers for HBV (1% and 4%), endoscopy in the previous 12 months (1% and 3%), arterial hypertension (1% and 3%), infectious conditions (1% and 3%), influenza or influenza-like symptoms (1% and 2%) and positive serological blood markers for HCV (1% and 2%). Summary/Conclusions: Several factors may have contributed to a limited number of new regular donors in the population, namely: ageing population, the alienation of the individual from the community induced by modern lifestyles and job precariousness. It is of the utmost importance to refine our blood donation campaigns according to the existing population of donors. The optimization of the blood donation potential of a population of donors must be achieved through the development of reliable and consistent screening methods. In order to appeal to new donors it is important to promote blood donations considering the profile of the regular and healthy blood donor of the existing population.

CLINICAL AND EPIDEMIOLOGICAL PROFILE OF ELDERLY PATIENTS WITH CHAGAS DISEASE FOLLOWED BETWEEN 2005-2013 BY PHARMACEUTICAL CARE SERVICE IN CEARÁ STATE, NORTHEASTERN BRAZIL

By controlling the transmission of Chagas disease, the challenge of providing assistance to millions of infected patients that reach old age arises. In this study, the socioeconomic, demographic and comorbidity records of all elderly chagasic patients followed at the Pharmaceutical Care Service of the Chagas Disease Research Laboratory were assessed. The information related to the clinical form of the disease was obtained from medical records provided by the Walter Cantídio University Hospital. The profile of the studied population was: women (50.5%); mean age of 67 years; retired (54.6%); married (51.6 %); high illiteracy rate (40.2%); and family income equal to the minimum wage (51.5%). The predominant clinical forms of Chagas disease were cardiac (65.3%) and indeterminate (14.7%). The main electrocardiographic changes were the right bundle branch block (41.0%), associated or not with the anterosuperior left bundle branch block (27.4%). The average number of comorbidities per patient was 2.23 ± 1.54, with systemic arterial hypertension being the main one found (67.0%). It was found that the elderly comprise a vulnerable group of patients that associate aging with cardiac and/or digestive disorders resulting from the evolution of Chagas disease and other comorbidities, which requires special attention from health services to ensure more appropriate medical and social care.
