Cardiorespiratory optimal point in post-COVID-19 patients: a cross-sectional study.

The varied clinical presentations of SARS-CoV-2 infection have raised concerns about long-term consequences, especially "long-COVID" or "post-COVID-19 syndrome." In this context, the cardiorespiratory optimal point (COP) within the Cardiopulmonary Exercise Test (CPET) emerges as a crucial metric for evaluating functional capacities and detecting cardiovascular and pulmonary anomalies post-COVID-19. This study aimed to assess COP values among post-COVID-19 patients and categorized them based on the initial severity of their disease. In this cross-sectional study conducted in the Northeast Brazil, 80 patients (26 females and 54 males) previously infected with SARS-CoV-2 underwent CPET. We clinically stratified patients into mild, moderate, or severe COVID-19 categories and assessed COP values and other cardiorespiratory metrics. We found differences in the predicted COP between patients with mild and severe COVID-19 (p=0.042). Additionally, patients with moderate and severe COVID-19 record had an average COP value exceeding 22. Other parameters, including respiratory exchange ratio, heart rate, and oxygen uptake efficiency slope, did not differ across the groups. Patients with a history of severe COVID-19 showed altered COP values, suggesting potential discrepancies in cardiovascular and respiratory system integration. The outcomes emphasize the importance of continuous monitoring and assessment of the cardiorespiratory domain for post-COVID-19 patients. Further research is needed to understand the relationship between elevated COP in post-severe COVID-19 and its long-term prognostic implications.

Exaggerated Systolic Blood Pressure Increase with Exercise and Myocardial Ischemia on Exercise Stress Echocardiography. / Resposta Exagerada da Pressão Arterial Sistólica ao Exercício e Isquemia Miocárdica à Ecocardiografia sob Estresse Físico.

BACKGROUND: Central Illustration : Exaggerated Systolic Blood Pressure Increase with Exercise and Myocardial Ischemia on Exercise Stress Echocardiography ESBPRE: exaggerated systolic blood pressure response to exercise; HR: heart rate; SBP: systolic blood pressure. BACKGROUND: The association between exaggerated systolic blood pressure response to exercise (ESBPRE) and myocardial ischemia is controversial and little studied in patients with established or suspected chronic coronary syndrome. OBJECTIVE: To verify the relationship between myocardial ischemia and ESBPRE in patients undergoing exercise stress echocardiography (ESE). METHODS: This is a cross-sectional study with 14,367 patients undergoing ESE, from January 2000 to January 2022, divided into the following 2 groups: G1, composed of patients whose peak systolic pressure increased ≥ 90 mmHg (value corresponding to the 95th percentile of the study population), and G2, patients who did not demonstrate an exaggerated hypertensive response. The groups were compared using Student's t and chi-square tests. P values < 0.05 were considered significant. Logistic regression was also performed to identify independent risk factors for myocardial ischemia, ESBPRE, complaints of typical chest pain prior to the exam, and angina during the test. RESULTS: Of the 14,367 patients, 1,500 (10.4%) developed ESBPRE, and 7,471 (52.0%) were female. The percentages of previous complaints of typical chest pain, angina during the test, and myocardial ischemia in patients with ESBPRE were 5.8%, 2.4% and 18.1%, compared to 7.4%, 3.9%, and 24.2%, in patients without ESBPRE, respectively (p = 0.021,p = 0.004, p < 0.001). In multivariate analysis, ESBPRE was independently associated with a lower probability of myocardial ischemia (odds ratio: 0.73; 95% confidence interval: 0.58 to 0.93; p = 0.009). CONCLUSION: Exaggerated increase in systolic blood pressure during ESE may be a marker for excluding myocardial ischemia.

Religiosity and Spirituality: The Relationship Between Psychosocial Factors and Cardiovascular Health

Abstract Background: Religiosity and Spirituality (R/S), despite being different entities, are multidimensional constructs, whose influence on cardiovascular health has been increasingly studied in recent decades. Objectives: To discriminate patients into subgroups according to R/S levels, in order to compare them regarding the distribution of cardiovascular comorbidities and clinical events. Methods: This is an observational, cross-sectional, analytical study. Two R/S scales were applied to a sample of patients seen at cardiology outpatient clinics. A cluster analysis was used to discriminate individuals into subgroups regarding R/S levels, which were subsequently compared regarding the frequencies of clinical variables related to cardiovascular health. A significance level of 5% was set for the statistical tests. Results: The sample included 237 patients with a mean age of 60.8 years (±10.7), of which 132 were female (55.7%). Cluster analysis (C) distinguished two groups: C1, with lower levels of R/S, and C2, with higher levels of R/S (p<0.001). C2 had a lower frequency of alcohol consumption (29.5% vs. 76.0%; p<0.001), smoking (12.9% vs. 51.0%; p<0.001), systemic arterial hypertension (SAH — 65.5% vs. 82.3%; p=0.005), dyslipidemia (58.3% vs. 77.1%; p=0.003), chronic coronary syndrome (36.7% vs. 58.3%; p=0.001), and prior cardiovascular events (15.8% vs. 36.5%; p<0.001) when compared to C1. There was also a higher frequency of females in C2 (82.0% vs. 17.7%; p<0.001). Conclusions: A better cardiovascular morbidity profile was observed in the group of patients with higher R/S levels, suggesting a probable positive relationship between R/S and cardiovascular health.

Non-Targeted Self-Measured Blood Pressure and Hypertension Control in Public and Private Health Systems in Brazil

Abstract Background: It is estimated that more than 30% of the Brazilian population has systemic arterial hypertension (SAH), and mostly as an uncontrolled disease. The most recent Brazilian Guideline of Hypertension recommends the practice of self-measurement of blood pressure (BP) as one of the strategies for a better control of SAH, but there is no consensus about the efficiency of this tool. Objective: To assess the control of SAH and the practice of non-targeted self-measured BP (SMBP) among hypertensive users of the Unified Health System (SUS) and the Supplementary Network (SN). Methods: This is a cross-sectional, observational, analytical study, with a stratified probability sample. One thousand volunteers were investigated, being 500 from SUS and 500 from the SN. Uni and multivariate analyses were performed considering a 5% significance level. Results: Patients from SUS presented inferior sociodemographic data (schooling, social status) in relation to those of the SN (p < 0.001), and showed lower control of SAH (p = 0.014), as well as more visits to the emergency room in the past year due to hypertension (p = 0.002), and fewer regular appointments with the cardiologist (p = 0.004). SMBP was equally present in both assessed groups (p = 0.567), even though users of the SN have been more advised to not conduct such a practice (p = 0.002). SMBP (p < 0.001) was an independent factor for uncontrolled SAH both in SUS (OR = 3.424) and in the SN (OR = 3.474). Conclusion: Patients in SUS presented lower SAH control. The practice of SMBP, mostly practiced with an uncalibrated digital device, was equally present in both groups and became an independent factor of uncontrolled SAH.

Resposta Exagerada da Pressão Arterial Sistólica ao Exercício e Isquemia Miocárdica à Ecocardiografia sob Estresse Físico / Exaggerated Systolic Blood Pressure Increase with Exercise and Myocardial Ischemia on Exercise Stress Echocardiography

Resumo Fundamento A associação entre resposta exagerada da pressão arterial sistólica ao exercício (REPASE) e isquemia miocárdica é controversa e pouco estudada em indivíduos com síndrome coronariana crônica estabelecida ou suspeita. Objetivo Verificar a relação entre isquemia miocárdica e REPASE em indivíduos submetidos à ecocardiografia sob estresse físico (EEF). Métodos Trata-se de estudo transversal com 14.367 indivíduos submetidos à EEF, de janeiro de 2000 a janeiro de 2022, divididos em dois grupos: G1 - composto por pacientes cuja pressão sistólica de pico apresentou incremento ≥ 90 mmHg (valor correspondente ao percentil 95 da população estudada) -, e G2 - formado por indivíduos que não apresentaram resposta hipertensiva exagerada. Os grupos foram comparados mediante os testes t de Student e qui-quadrado. Foram considerados significativos os valores de p < 0,05. Realizou-se, também, regressão logística para identificação de fatores de risco independentes para isquemia miocárdica, REPASE, queixa de precordialgia típica prévia ao exame e angina durante o teste. Resultados Dos 14.367 pacientes, 1.500 (10,4%) desenvolveram REPASE e 7.471 (52,0%) eram do sexo feminino. Os percentuais de queixa prévia de precordialgia típica, angina durante o teste e isquemia miocárdica dos pacientes com REPASE foram de 5,8%, 2,4% e 18,1% contra 7,4%, 3,9% e 24,2%, em indivíduos sem REPASE, respectivamente (p = 0,021, p = 0,004, p < 0,001). Na análise multivariada, a REPASE foi associada, independentemente, a uma menor probabilidade de isquemia miocárdica (odds ratio: 0,73; intervalo de confiança de 95%: 0,58 a 0,93; p = 0,009). Conclusão O incremento exagerado da pressão arterial sistólica durante a EEF pode ser um marcador de exclusão de isquemia miocárdica.

Subclinical Systolic Dysfunction during Chemotherapy for Breast Cancer

Abstract Background Cardiotoxicity is the main complication related to cancer therapy. Studies indicate that global longitudinal strain is an early detector of subclinical dysfunction of the left ventricle, preceding the decline in ejection fraction (EF). However, the reproducibility of such methodology has not been tested outside specialized centers. Objectives To assess the frequency of subclinical cardiotoxicity and to compare global longitudinal strain and EF measurements during the clinical course of patients undergoing chemotherapy for breast cancer. Methods This was an observational prospective study of 78 adult women who underwent serial echocardiograms (baseline and 1, 3, and 6 months after the beginning of chemotherapy), to evaluate biplane and 3D EF and global longitudinal strain. Cardiotoxicity and subclinical dysfunction were defined according to American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. Statistical significance was set at p < 0.05. Results The mean age of the patients was 50.1 ± 11.48 years. The frequency of subclinical cardiotoxicity (defined by global longitudinal strain) was 14.9% after 30 days of chemotherapy, 16.7% after 3 months, and 19.7% after 6 months, compared to 4.5%, 3%, and 6.6%, respectively, when clinical cardiotoxicity was determined according to EF. The group that developed subclinical cardiotoxicity by 30 days (group A) had a higher frequency of clinical cardiotoxicity at 3 months (p=0.028) and a lower mean biplane EF after 30 days (p= 0.036) than the group that showed no evidence of subclinical cardiotoxicity (group B). Conclusion Subclinical cardiotoxicity was frequent and began early, being associated with a drop in EF during the clinical course.

Prevalence of Burnout Syndrome and associated factors in medical students under different educational models.

OBJECTIVE: The objective of this study was to estimate the current prevalence of burnout syndrome among medical students at the Federal University of Sergipe and identify its associated factors. METHODS: This cross-sectional study was conducted with medical students randomly selected between April and June 2019. This study compared two medical schools from the same university with different teaching models: the Federal University of Sergipe, Aracaju campus, with a traditional teaching model, and the Federal University of Sergipe Lagarto campus, with a problem-based learning teaching model. An online questionnaire on the sociodemographic characteristics, personal aspects, and educational process of the participants, in addition to the Malash Burnout Inventory-Student Survey questionnaire for screening burnout syndrome, was distributed to the participants. The descriptive analysis of the data, calculation of the prevalence ratios, and multivariate analysis by logistic regression were performed. RESULTS: This study included 213 students with an average age of 23±3.77, and 50.2% of the students were male. Among the sample, 21.6% of the students met the three-dimensional criterion for burnout syndrome and 51.6% met the two-dimensional criterion. Burnout levels were higher in the students who rarely received the emotional support they needed in the program (OR 3.98), those who thought about dropping out of the undergraduate (OR 2.88), and those who considered their academic performance to be regular or weak (OR 12.1). The traditional teaching model was not a factor associated with burnout syndrome. CONCLUSIONS: The results suggest that a high prevalence of burnout syndrome is associated with psychosocial factors and the educational processes of medical students.

Non-Targeted Self-Measurement of Blood Pressure: Association with Self-Medication, Unscheduled Emergency Visits and Anxiety.

Background and Objective: The routine practice of self-medication of blood pressure (BP) not oriented with pulse devices may not be precisely useful in the control of BP and can lead the patient to self-medicate in error. Thus, we need to evaluate the non-oriented self-assessment of BP in real-life circumstances in hypertensive patients. The objective of this study was to evaluate in hypertensive patients the association of BP self-measurement with its control, as well as the presence of anxiety disorders, the occurrence of unscheduled visits to the emergency room, and self-medication. Materials and Methods: An observational study was carried out with 1000 hypertensive volunteers (age: 61.0 ± 12.5). Using a questionnaire, sociodemographic and clinical data on BP control were collected. Anxiety was assessed by the State-Trait Anxiety Inventory (STAI). Results: The group that performed non-oriented self-measurement of BP, showed that they had higher frequencies of self-medication (57.9%, p < 0.05) and more unscheduled visits to the emergency room (68%, p < 0.05). In addition, a lower level of BP control (46.8%, p < 0.05) was associated with higher levels of anxiety (52.3%, p < 0.05) in the group that performed non-oriented self-measurements of BP. Conclusion: The practice of non-oriented self-assessment of BP was associated with negative factors such as high levels of anxiety and higher frequencies of self-medication and unscheduled emergency visits.

Burnout Syndrome in medical internship students and its prevention with Balint Group.

BACKGROUND: We intend to estimate the Burnout Syndrome prevalence and its associated factors among medical internship students at a public university in northeastern Brasil, besides investigating the Balint Group (BG) contribution in its prevention. METHODS: We conducted a cross-sectional study in February/2018 with Medical Internship Students at the University researched. We applied a structured questionnaire developed by the authors about socio-demographic data, educational process with BG participation, and current psycho-emotional experiences, in addition to the Maslach Burnout Inventory - Student Survey (MBI-SS), for Burnout Syndrome screening. We performed descriptive data analysis, logistic regression, and cluster analysis. RESULTS: A total of 184 students (98%) participated in the study, with a mean age of 25.9±3.9 years, of which 54.9% were men. The prevalence of Burnout Syndrome was 10.3% based on the three-dimensional criterion and 35.9% on two-dimensional criterion (Exhaustion and Cynicism); it was higher in those who thought about quitting the program (OR=2.14), were dissatisfied with the teaching strategies (OR=2.67) and their performance (OR=2.64) and made use of licit drugs (OR=2.37). The variables associated with Burnout Syndrome allowed individuals to be discriminated, classifying them into three subgroups. Burnout Syndrome prevalence decreased, and vulnerability factors were attenuated when there was a higher frequency of students participating in BG. CONCLUSIONS: The prevalence of two-dimensional Burnout Syndrome was high, with factors associated with the educational process. Participation in BG was associated with a lower Burnout rate prevalence. Longitudinal studies should be conducted.

INTRODUÇÃO: A conscientização das gestantes é fundamental para experiências positivas de parto. OBJETIVO: Avaliar o grau de conhecimento das gestantes em dois serviços públicos sobre parto humanizado. Caracterizar epidemiologicamente a população estudada. MÉTODOS: Estudo descritivo realizado entre julho e agosto de 2017. Amostra com 297 gestantes foram selecionadas 200 após aplicação dos critérios de exclusão. Utilizados testes estatísticos de associações de variáveis (Qui-quadrado e Exato de Fisher). RESULTADOS: A média de idade das gestantes foi 26,6 anos. A maioria era procedente do interior do estado (72,5%), com renda até um salário mínimo (90,5%), e com mais de oito anos de estudo (62,5%). 71% iniciaram pré-natal até o primeiro trimestre e o pré-natal foi conduzido por médico em 72% dos casos. 71% preferiam parto normal e 44% tinha medo de cesárea. Profissional pré-natalista não ofereceu informações para 66,5%. 30,5% conhecia parto humanizado, destas 83,6% apresentaram conceito adequado. Houve associação entre conhecimento sobre parto humanizado e procedência (Aracaju) (p=0,03), maior renda (p=0,02), menor ocorrência de aborto (p=0,04), médico pré-natalista (p=0,04) preferência pelo parto vaginal (p=0,04). Dentre as que não conheciam o parto humanizado houve associação de respostas corretas com a maior renda (p=0,03) e anos estudados (p=0,02) e médico pré-natalista (p=0,01). CONCLUSÃO: A maioria desconhecia o parto humanizado, era procedente do interior com menor renda, preferência por parto normal, sem informações quanto aos tipos de parto pelo profissional executante (na maioria médicos), quem conhecia adequadamente. Conceitos adequados sobre parto humanizado mesmo na ausência de informação prévia associaram-se às variáveis socioeconômico e pré-natal.

INTRODUCTION: The awareness of pregnant women is fundamental to positive birth experiences. OBJECTIVE: To analyze the level of knowledge on humanized birth of pregnant women from two public services and characterize the sample epidemiologically. METHODS: Descriptive study using questionnaire between June and August 2017. Sample with 297 pregnant women being selected 200 after applying the exclusion criteria. Association test of variables were used (Chi-square and Fisher's exact test). RRESULTS: Mean age was 26.6 years. Majority were from countryside (72.5%), income up to a minimum wage (90.5%) and more of eight years of education (62.5%). 71% started prenatal care in the first trimester and it was conducted by physician in 71% of cases. 71% preferred vaginal delivery and 44% related fear of cesarean. Prenatal professional in charge did not provide information for 66.5%. 30.5% have heard about humanized childbirth, among these, 83.6% showed adequate concepts. Associations were observed between prior knowledge of humanized childbirth and origin (Aracaju) (p=0.03), higher income (p=0.02), lower abortion incidence (p=0.04), prenatal physician (p=0.04) and preference for normal childbirth (p=0.04). Among women without previous knowledge on humanized childbirth there association of correct concept with higher income (p=0.03), schooling (p=0.02) and prenatal physician (p=0.01). CONCLUSION: The majority did not know about humanized delivery, were from the countryside with lower income, preference for normal birth, were not informed on the types of delivery by the professional practitioner (in majority doctors), whom knew properly. Adequate concepts about humanized childbirth, even in the absence of prior information, were associated to socio-economic and prenatal variables.

RESUMO OBJETIVO: Estimar a prevalência de Síndrome de Burnout (SB) e fatores associados entre os internos de medicina de uma universidade pública no Nordeste do Brasil, além de investigar a contribuição do Grupo Balint (GB) na sua prevenção. MÉTODOS: Estudo transversal em fevereiro/2018 com os internos de medicina da universidade pesquisada. Aplicou-se um questionário estruturado elaborado pelos autores sobre características sociodemográficas, processo educacional com participação do GB e vivências psicoemocionais atuais, além do Maslach Burnout Inventory - Student Survey (MBI-SS) para triagem de SB. Realizaram-se análise descritiva, regressão logística e análise de agrupamentos. RESULTADOS: Participaram 184 estudantes (98%), com idade média de 25,9±3,9 anos, sendo 54,9% do sexo masculino. A prevalência de SB foi 10,3% pelo critério tridimensional e 35,9% pelo bidimensional (Exaustão e Descrença), sendo maior naqueles que pensaram em abandonar o curso (OR=2,14), estavam insatisfeitos com as estratégias de ensino (OR=2,67) e com seu desempenho acadêmico (OR=2,64) e faziam uso de drogas lícitas (OR=2,37). As variáveis associadas à SB permitiram discriminar os indivíduos classificando-os em três subgrupos. A prevalência de SB diminuiu e fatores de vulnerabilidade foram atenuados quando houve maior frequência de estudantes participantes do GB. CONCLUSÕES: A prevalência de SB pelo critério bidimensional foi alta, com fatores associados ao processo educacional. A participação no GB foi associada à menor prevalência de SB. Estudos longitudinais devem ser realizados.

A exequibilidade da implementação da angiotomografia de artérias coronárias em cidade de 600 mil habitantes / The feasibility of coronary artery angiography in 600,000 inhabitants

INTRODUÇÃO: As doenças cardiovasculares são responsáveis por alta mortalidade global. Buscando métodos diagnósticos para Doença Arterial Coronária (DAC) não invasivos, eficientes e de baixo custo, a Angiotomografia de Artérias Coronárias (ATCCor) permite avaliar a luz das artérias coronárias, sendo atualmente usada na Cardiologia. No intuito de oferecer esta metodologia numa capital do Nordeste, foi realizada a sua implementação e neste estudo avaliou-se a sua exequibilidade. OBJETIVO: Avaliar a exequibilidade da implementação da ATCCor estudando as suas indicações, as características dos pacientes em diferentes serviços e os resultados dos exames. MÉTODOS: Estudo observacional, transversal, analítico e prospectivo com 1293 pacientes submetidos a ATCCor. Comparou-se as características dos pacientes, a indicação do exame e seus resultados colhidos em nossa cidade com amostra de exames realizados anteriormente em um centro de imagem da região Sudeste. Foram incluídos 387 pacientes de um centro do sudeste, 151 de um centro do Sistema Único de Saúde do Nordeste e 755 de dois serviços da saúde suplementar do Nordeste (divididos em privado um com 327 e privado dois com 428). Utilizou-se a diretriz vigente para nortear as indicações dos exames. As variáveis quantitativas foram comparadas pelo Teste de Análise de Variância e as categóricas pelo Qui-Quadrado de Pearson. RESULTADOS: Houve diferença de idade entre os grupos (p=0,006), notou-se que nos serviços mais antigos a média de idade foi maior (59±11 anos). O sexo masculino foi predominante apenas no centro do sudeste (n=209, 54%). Fatores de risco como hipertensão arterial sistêmica, dislipidemia e antecedentes familiares apresentaram distribuição heterogênea, tendo o tempo de implementação do serviço como fator de semelhança...(AU)

Consumo leve a moderado de álcool e isquemia miocárdica à ecocardiografia sob estresse físico / Low to moderate alcohol consuption and myocardial ischemia on exercise stress echocardiography

Fundamento: O impacto do consumo de álcool na evolução da isquemia miocárdica permanece incerto. Os estudos divergem quanto a um eventual efeito cardioprotetor ou a um fator de risco cardiovascular desse consumo de maneira leve a moderada. Objetivo: Estudar a relação do consumo leve a moderado de álcool com a isquemia miocárdica à ecocardiografia sob estresse físico (EEF). Métodos: Estudo transversal composto por 6632 pacientes submetidos à EEF, de janeiro de 2000 a dezembro de 2015. Dividiram-se dois grupos: G1 - composto por 2130 (32,1%) pacientes com relato de consumo médio igual ou inferior a 1 dose de bebida alcoólica por dia para mulheres ou de 2 doses para homens; e G2 - formado por 4502 (67,9%) indivíduos que negaram consumo de álcool. A comparação entre os grupos foi feita mediante teste t de Student para variáveis quantitativas, e teste qui-quadrado ou teste de Fisher para as variáveis categóricas. Foram considerados significativos os valores de p < 0,05. Realizou-se, também, regressão logística para identificação de fatores de risco independentes para isquemia miocárdica. Resultados: G1 apresentou maior frequência de indivíduos do sexo masculino (77,1%; p < 0,001), menor idade média (54,8 ± 10,3 anos; p < 0,001) e maior frequência de isquemia miocárdica à EEF (p = 0,014). Idade, sexo masculino, dislipidemia, hipertensão arterial sistêmica, diabete melito, tabagismo e história familiar positiva apresentaram-se independentemente associados à presença de isquemia miocárdica à EEF. Não foi observada associação independente entre etilismo leve a moderado e isquemia miocárdica (OR 0,96; IC 95%: 0,83-1,11). No entanto, observou-se associação entre idade, sexo masculino, tabagismo e dislipidemia com o consumo de álcool. Conclusão: Etilismo leve a moderado não se apresentou como preditor independente de presença de isquemia miocárdica à EEF. Observou-se, no grupo dos etilistas, um predomínio de homens, dislipidêmicos e tabagistas, importantes variáveis preditoras de isquemia miocárdica

Background: The impact of alcohol consumption on the development of myocardial ischemia remains uncertain. Studies diverge whether low to moderate alcohol consumption provides cardioprotection or whether it is a risk factor for myocardial ischemia. Objective: To study the relationship between low to moderate alcohol consumption and myocardial ischemia on exercise stress echocardiography (ESE). Methods: Cross-sectional study with 6632 patients with known or suspected coronary artery disease undergoing ESE between January/2000 and December/2015. The patients were divided into two groups: G1, composed of 2130 (32.1%) patients whose report showed maximal consumption of 1 drink per day on average for women or of 2 drinks per day for men; G2, composed of individuals denying any alcohol consumption. For comparing between the groups, Student t test was used for quantitative variables, and chi-square test or Fisher exact test, for categorical variables. The significance level adopted was p < 0.05. Logistic regression was also used to evaluate independent risk factors for myocardial ischemia. Results: G1 had a higher number of men (77.1%; p < 0.001), lower mean age (54.8 ± 10.3 years old; p < 0.001) and higher frequency of myocardial ischemia on ESE (p = 0.014). Age, male sex, dyslipidemia, systemic arterial hypertension, diabetes mellitus, smoking and family history were independently associated with myocardial ischemia on ESE. Independent association between low to moderate alcohol consumption and myocardial ischemia on ESE (OR 0.96; 95%CI: 0.83 to 1.11) was not observed. However, age, male sex, smoking and dyslipidemia were associated with alcohol consumption. Conclusion: Low to moderate alcohol consumption was not an independent predictor of myocardial ischemia on ESE. Nevertheless, we observed a predominance of the male sex, dyslipidemia and smoking habit, important predictors of myocardial ischemia, in the group of alcohol consumers

Descrever as características clínicas dos pacientes com hemoglobinopatias do Hemocentro de Sergipe. Neste estudo transversal foram coletados dados clínicos dos pacientes portadores de hemoglobinopatias através da leitura dos prontuários. Realizou-se estatística descritiva e análise de variáveis utilizando-se o teste ANOVA para comparação de médias e o teste exato de Fisher para associação, utilizando em ambos uma significância com p<0,05. Foram coletados os dados de 96 pacientes. A principal hemoglobinopatia encontrada foi a SS (85,4%), seguida da SC (11,5%) e ßtalassemia (3,1%). A principal complicação encontrada foi a hiperferritinemia (50,7%), que teve uma relação direta com a hemotransfusão (p=0,039) e os pacientes com mais complicações tinham uma maior idade (p=0,026). A hemotransfusão foi necessária em 71,9% dos pacientes, enquanto que a hidroxiureia e o deserafirox em 40,6% e 13,5%, respectivamente. A principal hemoglobinopatia encontrada foi SS, teve como principal complicação a hiperferritinemia e o principal tratamento realizado foi a hemotransfusão.

To describe the clinical characteristics of patients with hemoglobinopathies at the Blood Center of Sergipe. In this cross-sectional study, clinical data were collected from patients with hemoglobinopathies by reading the medical records. Descriptive statistics and variable analysis were performed using the ANOVA test for comparison of means and Fisher's exact test for association, using a significance level of p<0.05. Data were collected from 96 patients. The main hemoglobinopathy found was SS (85.4%), followed by SC (11.5%) and ß-thalassemia (3.1%). The main complication was hyperferritinemia (50.7%), which had a direct relationship with blood transfusion (p=0.039) and patients with more complications had an older age (p=0.026). Hemotransfusion was required in 71.9% of the patients, whereas hydroxyurea and deserafirox in 40.6% and 13.5%, respectively. The main hemoglobinopathy found was SS, the main complication was hyperferritinemia and the main treatment was hemotransfusion.

Atherosclerotic Plaque in Patients with Zero Calcium Score at Coronary Computed Tomography Angiography.

BACKGROUND: In view of the high mortality for cardiovascular diseases, it has become necessary to stratify the main risk factors and to choose the correct diagnostic modality. Studies have demonstrated that a zero calcium score (CS) is characteristic of a low risk for cardiovascular events. However, the prevalence of individuals with coronary atherosclerotic plaques and zero CS is conflicting in the specialized literature. OBJECTIVE: To evaluate the frequency of patients with coronary atherosclerotic plaques, their degree of obstruction and associated factors in patients with zero CS and indication for coronary computed tomography angiography (CCTA). METHODS: This is a cross-sectional, prospective study with 367 volunteers with zero CS at CCTA in four diagnostic imaging centers in the period from 2011 to 2016. A significance level of 5% and 95% confidence interval were adopted. RESULTS: The frequency of atherosclerotic plaque in the coronary arteries in 367 patients with zero CS was 9.3% (34 individuals). In this subgroup, mean age was 52 ± 10 years, 18 (52.9%) were women and 16 (47%) had significant coronary obstructions (> 50%), with involvement of two or more segments in 4 (25%) patients. The frequency of non-obese individuals (90.6% vs 73.9%, p = 0.037) and alcohol drinkers (55.9% vs 34.8%, p = 0.015) was significantly higher in patients with atherosclerotic plaques, with an odds ratio of 3.4 for each of this variable. CONCLUSIONS: The frequency of atherosclerotic plaque with zero CS was relatively high, indicating that the absence of calcification does not exclude the presence of plaques, many of which obstructive, especially in non-obese subjects and alcohol drinkers.

Resumo Fundamento: Diante da alta mortalidade por doenças cardiovasculares, faz-se necessária a estratificação dos principais fatores de riscos e escolha correta da modalidade diagnóstica. Estudos demonstraram que escore de cálcio (EC) zero caracteriza baixo risco de eventos cardiovasculares. No entanto, a frequência de portadores de placa aterosclerótica coronária com EC zero é conflitante na literatura especializada. Objetivo: Avaliar a frequência de pacientes com placa aterosclerótica coronária, seu grau de obstrução e fatores associados em pacientes com EC zero e indicação para angiotomografia computadorizada de coronárias (ATCC). Métodos: Trata-se de estudo transversal, prospectivo, com 367 voluntários portadores de EC zero, mediante a ATCC, no período de 2011-16, em quatro centros de diagnóstico por imagem. Foi assumido nível de significância 5% e intervalo de confiança de 95%. Resultados: A frequência de placa aterosclerótica nas artérias coronárias dos 367 pacientes com EC zero foi de 9,3% (34 indivíduos); neste subgrupo, a média de idade foi 52 ± 10 anos, 18 (52,9%) eram mulheres e 16 (47%) exibiam obstruções coronarianas significativas (> 50%), dos quais 4 (25%) apresentaram placas em pelo menos dois segmentos. A frequência de não obesos (90,6% vs. 73,9%; p = 0,037) e de etilistas (55,9% vs. 34,8%; p = 0,015) foi significativamente maior nos portadores de placa, apresentando, cada variável, odds ratio de 3,4 para o desenvolvimento das referidas placas. Conclusões: A frequência de placa aterosclerótica com EC zero foi considerável, evidenciando, portanto, que a ausência de calcificação não exclui placa, muitas das quais obstrutivas, principalmente nos não obesos e etilistas.

Cardiopulmonary exercise testing in patients with left bundle branch block and preserved ejection fraction / Teste de Esforço cardiopulmonar em portadores de bloqueio do ramo esquerdo e fração de ejeção preservada

BACKGROUND: Left bundle branch block (LBBB) has prognostic significance in patients with congestive heart failure. However, its influence is not well established in patients with preserved systolic ventricular function. OBJECTIVE: To evaluate the implications of LBBB presence in the cardiovascular performance of patients with preserved left ventricular systolic function (LVEF). METHODS: 26 LBBB patients (61.3 ± 8.2 years of age) and 23 healthy individuals (58 ± 6.8 years of age) with LVEF > 0.5 underwent cardiopulmonary exercise testing (CPET). RESULTS: CPET analysis revealed: peak oxygen consumption (VO2 ) predicted in the LBBB group was 87.2 ± 15.0% versus 105.0 ± 15.6% (p < 0.0001); peak oxygen pulse predicted in LBBB group was 98.6 ± 18.6% vs 109.9 ± 13.5% (p = 0.02); VO2 predicted anaerobic threshold in LBBB group was 67.9 ± 13.6% vs 70.2 ± 12.8% (p = 0.55); ΔVO2 /Δload in the LBBB group was 15.5 ± 5.51 versus 20.7 ± 7.3 ml.min-1.watts-1 (p = 0.006); ventilation / carbon dioxide production (VE/VCO2 slope) in LBBB group was 29.8 ± 2.9 versus 26.2 ± 2.9 (p = 0.0001) and VO2 recovery time in the LBBB group was 85.2 ± 11.8 vs. 71.5 ± 11.0 seconds (p = 0.0001). LBBB was an independent marker for VE/VCO2 slope increase. CONCLUSION: LBBB presence in individuals with preserved LVEF did not affect cardiovascular performance, but there was an increase of the VE/VCO2 slope in comparison to the control group.

FUNDAMENTO: O bloqueio do ramo esquerdo (BRE) tem importância prognóstica em portadores de insuficiência cardíaca congestiva. Todavia, a sua influência não está bem estabelecida em pacientes com função ventricular sistólica preservada. OBJETIVO: Avaliar as implicações da presença do BRE no desempenho cardiovascular em pacientes com função sistólica do ventrículo esquerdo (FEVE) preservada. MÉTODOS: Foram submetidos ao teste de esforço cardiopulmonar (TECP), 26 portadores de BRE (61,3 ± 8,2 anos) e 23 indivíduos saudáveis (58 ± 6,8 anos), com FEVE > 0,5. RESULTADOS: A análise do TECP revelou: consumo de oxigênio (VO2 ) pico predito no grupo BRE foi de 87,2 ± 15,0% versus 105,0 ± 15,6% (p < 0,0001); pulso de oxigênio pico predito no grupo BRE foi de 98,6 ± 18,6% versus 109,9 ± 13,5%, (p = 0,02); VO2 predito limiar anaeróbico no grupo BRE foi de 67,9 ± 13,6 % versus 70,2 ± 12,8% (p = 0,55); ∆VO2 /∆carga no grupo BRE foi de 15,5 ± 5,51 versus 20,7 ± 7,3 ml.min-1.watts-1 (p = 0,006); relação ventilação/produção de dióxido de carbono (VE/VCO2 slope) no grupo BRE foi de 29,8 ± 2,9 versus 26,2 ± 2,9 (p = 0,0001) e tempo de recuperação do VO2 no grupo BRE foi de 85,2 ± 11,8 versus 71,5 ± 11,0 segundos (p = 0,0001). O BRE foi marcador independente para o aumento do VE/VCO2 slope. CONCLUSÃO: A presença de BRE em indivíduos com FEVE preservada não comprometeu o desempenho cardiovascular, mas houve aumento do VE/VCO2 slope em relação ao grupo controle.

Preditores de Placa Aterosclerótica em Assintomáticos Isquêmicos à Ecocardiografia sob Estresse Físico / Predictors of Atherosclerotic Plaque in Individuals with Asymptomatic Ischemia on Physical Stress Echocardiography

A isquemia miocárdica pode ocorrer em pacientes assintomáticos e sem história de doença arterial coronariana (DAC). A ecocardiografia sob estresse físico (EEF) é um método de boa acurácia diagnóstica, enquanto a cineangiocoronariografia (CATE) é o método padrão-ouro para detecção de DAC obstrutiva. Todavia, muitos portadores de isquemia em testes funcionais apresentam lesões não obstrutivas à CATE. Objetivo: Identificar a presença de preditores de placas ateroscleróticas obstrutivas à CATE em indivíduos assintomáticos com EEF positiva para isquemia miocárdica. Métodos: Estudo transversal com 278 pacientes assintomáticos submetidos à EEF e à CATE, divididos em grupo G1 (lesões ateroscleróticas obstrutivas ≥ 50%) e G2 (placas inferiores a 50% ou inexistentes). Variáveis quantitativas foram comparadas com os testes t de Student ou Mann-Whitney para grupos independentes, segundo a normalidade da amostra. Para variáveis categóricas, utilizou-se os testes do qui-quadrado ou exato de Fisher, quando apropriado. Para identificação de preditores independentes de lesão aterosclerótica, foi utilizada regressão logística. Resultados: O número de pacientes nos grupos G1 e G2 foi de 233 (83,3%) e 45 (16,2%), respectivamente. A média de idade foi maior no G1 (60,9 ± 9,56 anos versus 51,8 ± 10,05 anos, respectivamente, p < 0,001). O G1 em comparação ao G2 apresentou mais pacientes hipertensos (65,2% versus 48,9%, p = 0,03) e dislipidêmicos (77,3% versus 57,8%, respectivamente, p = 0,006). O G2 em comparação ao G1 apresentou maior frequência de obesidade leve (33,3% versus 14,2%, respectivamente, p = 0,002), que demonstrou ser um fator protetor para lesão aterosclerótica. Conclusão: Os preditores de placa aterosclerótica em assintomáticos isquêmicos à EEF foram idade, gênero masculino e isquemia do tipo fixa.

Myocardial ischemia may occur in asymptomatic patients without a history of coronary artery disease (CAD). Stress echocardiography (SE) is a method with good diagnostic accuracy, while coronary cineangiography (CCA) is the gold standard method to detect obstructive CAD. However, many patients with ischemia on functional tests show nonobstructive lesions on CCA. Objective: To assess the presence of predictors of obstructive atherosclerotic plaques in asymptomatic individuals with an SE positive for myocardial ischemia. Methods: Cross-sectional study with 278 asymptomatic individuals who underwent SE and CCA, divided into groups G1 (obstructive atherosclerotic lesions ≥ 50%) and G2 (plaques below 50% or nonexistent). Quantitative variables were compared with Student's t test or Mann-Whitney test for independent groups, according to the normality of the sample. For categorical variables, we used the chi-square test or Fisher's exact test, as appropriate. Logistic regression was used to identify independent predictors of atherosclerotic lesions. Results: The numbers of patients in G1 and G2 were 233 (83.3%) and 45 (16.2%), respectively. The mean age was higher in G1 (60.9 ± 9.56 years versus 51.8 ± 10.05 years, p < 0.001). G1, when compared with G2, had more patients with hypertension (65.2% versus 48.9%, respectively, p = 0.03) and dyslipidemia (77.3% versus 57.8%, respectively, p = 0.006). G2, when compared with G1, had a higher frequency of mild obesity (33.3% versus 14.2%, respectively, p = 0.002), which emerged as a protective factor for atherosclerotic lesions. Conclusion: The predictors of atherosclerotic plaques in asymptomatic patients with ischemia on SE were age, male gender, and fixed ischemia.
