Abstract Background The long-term effects of mild COVID-19 on physical, cognitive, and mental health are not yet well understood. Objective The purpose of this paper is to describe the protocol for the ongoing “Post-COVID Brazil” study 2, which aims to evaluate the factors associated with health-related quality of life and long-term cardiovascular and non-cardiovascular outcomes one year after a mild episode of symptomatic COVID-19. Methods The “Post-COVID Brazil” study 2 is a prospective multicenter study that plans to enroll 1047 patients (NCT05197647). Centralized, structured telephone interviews are conducted at 1, 3, 6, 9, and 12 months after COVID-19 diagnosis. The primary outcome is the health-related quality-of-life utility score, assessed using the EuroQol-5D-3L (EQ-5D-3L) questionnaire at 12 months. Secondary endpoints include the EQ-5D-3L at 3, 6, and 9 months, as well as all-cause mortality, major cardiovascular events, hospitalization, return to work or education, persistent symptoms, new disabilities in instrumental activities of daily living, cognitive impairment, anxiety, depression, and post-traumatic stress symptoms at 3, 6, 9, and 12 months after SARS-CoV-2 infection. A p-value < 0.05 will be considered statistically significant for all analyses. Results The primary endpoint will be presented as the overall frequency of the EQ-5D-3L domains 12 months after SARS-CoV-2 infection. Main analysis will explore the association of independent variables with the study outcomes. Conclusion The “Post-COVID Brazil” study 2 aims to clarify the impact of long COVID on the quality of life and cardiovascular and non-cardiovascular outcomes of Brazilian patients who have had mild COVID-19.

Resumo Fundamento Os efeitos em longo prazo da COVID-19 leve sobre a saúde física, mental e cognitiva ainda não são bem conhecidos. Objetivo Este artigo visa descrever o protocolo para o estudo em andamento Pós-COVID Brasil 2, o qual tem como objetivo avaliar os fatores associados à qualidade de vida associada à saúde e desfechos cardiovasculares e não cardiovasculares de longo prazo um ano após um episódio de COVID-19 sintomática leve. Métodos O estudo “Pós-COVID Brasil 2” é um estudo multicêntrico prospectivo que pretende incluir 1047 pacientes (NCT05197647). Entrevistas estruturas, centralizadas são conduzidas em um mês, e aos três, seis, nove e 12 meses após o diagnóstico de COVID-19. O desfecho primário é o escore de utilidade da qualidade de vida relacionada à saúde, avaliado usando o questionário EuroQol-5D-3L (EQ-5D-3L) aos 12 meses. Desfechos secundários incluem o EQ-5D-3L aos três, seis e nove meses, mortalidade por todas as causas, eventos cardiovasculares maiores, hospitalização, retorno ao trabalho ou à escola, sintomas persistentes, novas incapacidades em atividades instrumentais diárias, déficit cognitivo, ansiedade, depressão, e sintomas de transtorno do estresse pós-traumático as três, seis, nove e doze meses após a infecção pelo SARS-CoV-2. Um valor de p<0,05 será considerado estatisticamente significativo para as análises. Resultados O desfecho primário será apresentado como frequência dos domínios do EQ-5D-3L doze meses após a infecção por SARS-CoV-2. A análise principal explorará a associação das variáveis independentes com os desfechos do estudo. Conclusão O estudo “Pós-COVID Brasil 2” tem como objetivo elucidar o impacto da COVID longa sobre a qualidade de vida e desfechos cardiovasculares e não cardiovasculares de brasileiros pacientes que apresentaram COVID-19 leve.

Abstract Background The long-term impact of hospitalization for COVID-19 on patients’ physical, mental, and cognitive health still needs further assessment. Objectives This study aims to evaluate factors associated with quality of life and cardiovascular and non-cardiovascular outcomes 12 months after hospitalization for COVID-19. Methods This prospective multicenter study intends to enroll 611 patients hospitalized due to COVID-19 (NCT05165979). Centralized telephone interviews are scheduled to occur at three, six, nine, and 12 months after hospital discharge. The primary endpoint is defined as the health-related quality-of-life utility score assessed by the EuroQol-5D-3L (EQ-5D-3L) questionnaire at 12 months. Secondary endpoints are defined as the EQ-5D-3L at three, six and nine months, return to work or education, persistent symptoms, new disabilities in instrumental activities of daily living, cognitive impairment, anxiety, depression, and post-traumatic stress symptoms, major cardiovascular events, rehospitalization, as well as all-cause mortality at 3, 6, 9, and 12 months after SARS-CoV-2 infection. A p-value <0.05 will be assumed as statistically significant for all analyses. Results The primary endpoint will be presented as the frequency of the EQ-5D-3L score 12 months after COVID-19 hospitalization. A sub-analysis to identify possible associations of independent variables with study outcomes will be presented. Conclusions This study will determine the impact of COVID-19 on the quality of life and cardiovascular and non-cardiovascular outcomes of hospitalized patients 12 months after discharge providing insights to the public health system in Brazil.

Resumo A angiografia coronariana por tomografia computadorizada (ACTC) assumiu um papel de destaque na avaliação da doença arterial coronariana. Entretanto, sua natureza anatômica não permitia a avaliação da repercussão funcional das obstruções coronarianas. Recentemente, tornou-se possível a avaliação da perfusão miocárdica por tomografia computadorizada (PMTC), baseando-se nas alterações de contrastação miocárdicas relacionadas às estenoses coronarianas. Diversos estudos permitiram validar esta técnica perante o método anatômico de referência (cateterismo cardíaco) e outros métodos funcionais, incluindo cintilografia de perfusão miocárdica e a reserva de fluxo fracionada. A PMTC é realizada conjuntamente com a ACTC, em uma análise combinada de anatomia e função. A fase de estresse (com avaliação da perfusão miocárdica) pode ser realizada antes ou depois da fase de repouso (avaliação da perfusão de repouso e artérias coronárias), e diferentes parâmetros de aquisição são propostos conforme o protocolo e o tipo de equipamento utilizados. Os agentes estressores utilizados baseiam-se na vasodilatação coronariana (ex: dipiridamol, adenosina). A interpretação das imagens, semelhante a outros métodos de avaliação perfusional, baseia-se na identificação e quantificação de defeitos de perfusão miocárdicos. A integração dos achados perfusionais e anatômicos é parte fundamental do algoritmo de interpretação do exame, permitindo definir se as estenoses identificadas são hemodinamicamente significativas, podendo se relacionar com isquemia miocárdica.

Abstract Coronary computed tomography angiography (CCTA) has gained a prominent role in the evaluation of coronary artery disease. However, its anatomical nature does not allow the evaluation of the functional repercussion of coronary obstructions. It has been made possible to evaluate Myocardial computed tomography perfusion (Myocardial CTP) recently, based on myocardial contrast changes related to coronary stenoses. Several studies have validated this technique against the anatomical reference method (cardiac catheterization) and other functional methods, including myocardial perfusion scintigraphy and fractional flow reserve. The Myocardial CTP is performed in conjunction with the CCTA, a combined analysis of anatomy and function. The stress phase (with assessment of myocardial perfusion) can be performed before or after the resting phase (assessment of resting perfusion and coronary arteries), and different acquisition parameters are proposed according to the protocol and type of equipment used. Stressors used are based on coronary vasodilation (e.g. dipyridamole, adenosine). Image interpretation, similar to other perfusion assessment methods, is based on the identification and quantification of myocardial perfusion defects. The integration of both perfusion and anatomical findings is fundamental for the examination interpretation algorithm, allowing to define if the stenoses identified are hemodynamically significant and may be related to myocardial ischemia.

Abstract Coronary artery calcification is an early marker of subclinical atherosclerosis, but little research has been done in asymptomatic individuals under 45 years. In this cohort study with 17 years of follow-up, 155 participants were assessed in 2016 with a coronary calcium score for the association with cardiovascular risk factors. During follow-up, there was a significant increase in anthropometric measurements, cholesterol and fractions, and diastolic pressure. Participants who gained 1 cm in waist circumference had a mean reduction of 0.36 mg/dL in HDL-cholesterol and those who gained 1 kg/m2 in body mass index had a reduction of 0.72 mg/dL in HDL-cholesterol. Married participants had a 4.78 mg/dL reduction in HDL-cholesterol levels compared to singles. There was an increase of 2.09 mg/dL in HDL-cholesterol at each higher level of self-perceived health. One single case, a 32-year-old male, smoker, sedentary individual with a family history of cardiovascular disease, presented coronary calcification (0.6%). His HDL-cholesterol was reduced by 43.4%, with levels of less than 25 mg/dL at the time of coronary calcium scoring. Our findings may prompt broader studies of populations under 35 years with HDL-C levels below 25 mg/dL and family histories of cardiovascular disease, associated with obesity, sedentary lifestyle and smoking.

FUNDAMENTO: Testes invasivos e não invasivos têm sido usados para identificar risco para Taquicardia Ventricular (TV) em pacientes com Cardiopatia Chagásica Crônica (CCC). Ressonância Magnética Cardíaca (RMC) pela técnica do Realce Tardio (RT) pode ser útil para selecionar pacientes com disfunção ventricular global ou segmentar, com alto grau de fibrose e maior risco para TV clínica. OBJETIVO: Melhorar a identificação de elementos preditivos de TV em pacientes com CCC. MÉTODO: Quarenta e um pacientes com CCC foram pesquisados, sendo 30 (72%) do sexo masculino, com média de idade de 55,1 ± 11,9 anos. Vinte e seis pacientes apresentavam histórico de TV (grupo TV), e 15 não apresentavam TV (grupo NTV). Todos os pacientes incluídos tinham RT e disfunção segmentar ventricular. Volume, porcentagem de comprometimento da espessura da parede ventricular em cada segmento, e distribuição de RT foi determinado em cada caso. RESULTADOS: Não houve diferença estatística em termos de volume de RT entre os dois grupos: grupo TV = 30,0 ± 16,2%; grupo NTV = 21,7 ± 15,7%; p = 0,118. A probabilidade de TV foi maior se duas ou mais áreas contíguas de fibrose transmural estivessem presentes, sendo um fator preditor de TV clínica (RR 4,1; p = 0,04). A concordância entre os observadores foi de 100% nesse critério (p < 0,001). CONCLUSÃO: A identificação de dois ou mais segmentos de RT transmural por RMC está associado com a ocorrência de TV clínica em pacientes com CCC. Portanto, a RMC melhora a estratificação de risco na população estudada. (Arq Bras Cardiol. 2012; [online].ahead print, PP.0-0)

BACKGROUND: Invasive and non-invasive tests have been used to identify the risk of ventricular tachycardia (VT) in patients with chronic Chagas' heart disease (CCHD). Cardiac magnetic resonance imaging (CMRI) using the delayed enhancement (DE) technique can be useful to select patients with global or segmentary ventricular dysfunction, with high degree of fibrosis and at higher risk for clinical VT. OBJECTIVE: To improve the identification of predictors of VT in patients with CCHD. METHOD: This study assessed 41 patients with CCHD [30 (72%) males; mean age, 55.1 ± 11.9 years]. Twenty-six patients had history of VT (VT group), and 15 had no VT (NVT group). All patients enrolled had DE and segmentary ventricular dysfunction. In each case, the following variables were determined: left ventricular volume; percentage of ventricular wall thickness impairment in each segment; and DE distribution. RESULTS: No statistical difference regarding the DE volume between both groups was observed: VT group = 30.0 ± 16.2%; NVT group = 21.7 ± 15.7%; p = 0.118. The probability of VT was greater in the presence of two or more contiguous transmural fibrosis areas, and that was a predictive factor of clinical VT (RR 4.1; p = 0,04). Agreement between observers was 100% regarding that criterion (p < 0.001). CONCLUSION: The identification of two or more segments of transmural DE by use of CMRI is associated with the occurrence of clinical VT in patients with CCHD. Thus, CMRI improved risk stratification in the population studied. (Arq Bras Cardiol. 2012; [online].ahead print, PP.0-0)

Divertículos ventriculares congênitos são raros. Clinicamente, podem ser assintomáticos ou causa de embolização sistêmica, insuficiência cardíaca, insuficiência valvar, ruptura ventricular, arritmia ventricular ou morte súbita. Apresentamos caso de uma mulher de 56 anos com taquicardia ventricular sustentada, na qual, durante a investigação, foi diagnosticada a presença de um divertículo na posição ínfero-basal do ventrículo esquerdo. Comentam-se as características clínicas e o tratamento desta doença infreqüente.

Congenital ventricular diverticula are rare. Clinically, they may be asymptomatic or cause systemic embolization, heart failure, valvular regurgitation, ventricular rupture, ventricular arrhythmia, or sudden death. We report the case of a 56-year-old woman with sustained ventricular tachycardia, who, during investigation, was diagnosed with a diverticulum in the inferobasal portion of the left ventricle. The clinical characteristics and treatment of this rare disease are discussed.

OBJECTIVE: To describe echocardiographic measurements and left ventricular mass in a population sample of healthy adults inhabitants of the urban region of Porto Alegre. METHODS: An analytical, observational, population-based, cross-sectional study was done. Through a multi-stage probability sample, 114 individuals were selected to be submitted to a M-mode and two-dimensional echocardiogram with color Doppler. The analyses were restricted to healthy participants. Echocardiographic measurements were described by mean, standard deviation, 95 percentile and 95% confidence limits. RESULTS: A total of 100 healthy participants, with several characteristics similar to those from the original population, had a complete and reliable echocardiographic examination. The measurements of aorta, left atrium, interventricular septum, left ventricle in systole and diastole, left posterior wall and left ventricular mass, adjusted or not for body surface area or height, were significantly higher in males. The right ventricle size was similar among the genders. Several echocardiographic measurements were within standard normal limits. Interventricular septum, left posterior wall and left ventricular mass, adjusted or not for anthropometric measurements, and aortic dimensions had lower mean and range than the reference limits. CONCLUSION: The means and estimates of distribution for the measurements of interventricular septum, left posterior wall and left ventricular mass found in this survey were lower than those indicated by the international literature and accepted as normal limits.
