RESUMEN
Background: The obesity occurrence has achieved epidemic levels worldwide and several studies indicate a paradoxical similarity among obesity and the prognosis in heart failure (HF). The primary objective was to understand the association between body mass index (BMI) and heart failure with reduced ejection fraction (HFREF) of ischemic etiology in outpatients, using mortality as a parameter. The secondary objectives were to determine the differences in HF functional class, pharmacological therapy and evaluate the prognostic value of MAGGIC Score in this population. Methods: We analyzed 1,556 medical records from the HF outpatient clinic of a quaternary hospital and 242 were selected according to the criteria. Most were male, average age 62.6 (56-70), BMI 18.5-24.9 = 35.1%, 25-29.9 = 37.2%, 30-34.9 = 17.8%, 35-39.9 = 7%; BMI <18.5 and >40 groups were eliminated from the central analyzes because of scarce testing. Results: BMI 30-34.9 and BMI 18.5-24.9 had the best prognosis, BMI 25-29.9 had an average performance, and BMI -39.9 group provided the worst outcome (p = 0.123). In the subcategory analysis, BMI 30-34.9 group had a better prognosis compared to the BMI 35-39.9 group (p = 0.033). In the multivariate analysis The MAGGIC score was not able to foretell mortality in this population according to BMI. Conclusion: In not hospitalized patients with HFREF of ischemic etiology, obesity was not a protective factor.
RESUMEN
OBJECTIVES: To assess the efficacy of hydroxychloroquine in combination with azithromycin in terms of clinical and biochemical outcomes in adult patients with COVID-19 hospitalized for acute respiratory distress syndrome (ARDS), and to describe the occurrence of adverse events. METHOD: Retrospective comparative study, based in a quaternary private hospital in Rio de Janeiro, Brazil, involving 193 adult patients hospitalized for mild and moderate COVID-19 related ARSD, analyzing treatment efficacy based on clinical and biochemical outcomes. RESULTS: The active group comprised 101 (52.3%) patients using hydroxychloroquine associated with azithromycin and the control group 92 (47.7%) patients who did not take these medications. Median age was 59 (47-70) in the active group and 65 (47-77) in the control group (pâ¯<â¯0.05). Patients in the control group had greater extent of pulmonary involvement on baseline chest CT scans (pâ¯<â¯0.05). All other baseline variables (BMI, comorbidities, previous use of medications and biochemical assessments) were similar between groups. In the medication group, 25% (25 out of 101) were admitted to the ICU, compared to 21% (19 out of 92) in the control group (pâ¯>â¯0.05). No difference in mortality, duration of non-invasive oxygen use or duration of hospitalization was seen between groups. The therapeutic regimen was well tolerated, with only eight (7.9%) patients presenting gastrointestinal symptoms and eight (7.9%) patients withdrawn treatment due to QTc prolongation. CONCLUSIONS: Patients treated with hydroxychloroquine combined with azithromycin and the control group had similar clinical outcomes. This therapeutic regimen was considered ineffective in hospitalized patients with mild to moderate COVID-19 related ARDS and was associated with few non-severe adverse events.

A hipertensão arterial sistêmica (HAS) afeta aproximadamente 30% da população geral no mundo industrializado e é uma das principais causas de doença renal crônica (DRC), caracterizada por função renal anormal ou danos estruturais renais com mais de 3 meses de duração. A sua presença classifica o paciente hipertenso como de alto risco cardiovascular (CV). O controle pressórico é fundamental para diminuir a sua progressão e reduzir o risco de morbidade e mortalidade CV. A meta pressórica recomendada deve ser menor que 130x80mmHg para a maioria dos pacientes com DRC. O tratamento não medicamentoso tem como base as mesmas recomendações dos demais pacientes hipertensos. A terapia medicamentosa combinada deve ser iniciada o mais breve possível. Além dos inibidores do sistema renina angiotensina aldosterona, conhecidos por sua eficácia na DRC, os diuréticos e os bloqueadores de canal de cálcio compõem o trio de ouro utilizado no tratamento da HAS, capazes de reduzir o risco cardiovascular e desacelerar a progressão da doença renal. Em conclusão, a DRC é um preditor de risco CV e a presença concomitante de HAS aumenta expressivamente esse risco. A utilização da estratégia terapêutica adequada para manter os níveis pressóricos dentro das metas é fundamental na atenuação da progressão da doença renal e do risco
Systemic arterial hypertension (SAH) affects approximately 30% of the general population in the industrialized world and is a major cause of chronic kidney disease (CKD), characterized by abnormal renal function or structural damage lasting more than 3 months. Its presence classifies the hypertensive as a high cardiovascular (CV) risk patient. Blood pressure (BP) control is essential for slowing the progression and for reducing the risk of CV morbidity and mortality in patients with CKD. BP target <130x80mmHg is recommended for most hypertensives with CKD. Non pharmacological treatment is based on the same recommendations for other hypertensive patients. Combination drug therapy should be started as soon as possible. In addition to the renin angiotensin aldosterone system blockers, known for their effectiveness in CKD, diuretics and calcium channel blockers compose the gold trio used in the treatment of SAH, able to reduce cardiovascular risk and to slow the progression of kidney disease. In conclusion, CKD is a predictor of CV risk and the concomitant presence of SAH significantly increases this risk. The use of an appropriate therapeutic strategy to maintain BP control is crucial to mitigate the progression of kidney disease and CV

The absence of a consensus about the diagnostic criteria for acute cardiorenal syndrome (ACRS) affects its prognosis. This study aimed at assessing the diagnostic criteria for ACRS and their impact on prognosis. A systematic review was conducted using PRISMA methodology and PICO criteria in the MEDLINE, EMBASE and LILACS databases. The search included original publications, such as clinical trials, cohort studies, case-control studies, and meta-analyses, issued from January 1998 to June 2018. Neither literature nor heart failure guidelines provided a clear definition of the diagnostic criteria for ACRS. The serum creatinine increase by at least 0.3 mg/dL from baseline creatinine is the most used diagnostic criterion. However, the definition of baseline creatinine, as well as which serum creatinine should be used as reference for critical patients, is still controversial. This systematic review suggests that ACRS criteria should be revised to include the diagnosis of ACRS on hospital admission. Reference serum creatinine should reflect baseline renal function before the beginning of acute kidney injury.

Resumo A indefinição de critérios diagnósticos para síndrome cardiorrenal aguda (SCRA) impacta em diferentes resultados prognósticos. Objetivou-se avaliar os critérios diagnósticos da SCRA e o impacto no prognóstico. Procedeu-se à revisão sistemática utilizando-se a metodologia PRISMA e os critérios PICO nas bases MEDLINE, EMBASE e LILACS. A pesquisa incluiu artigos originais do tipo ensaio clínico, coorte, caso-controle e meta-análises publicados no período de janeiro de 1998 até junho de 2018. Não foi encontrada na literatura nem nas diretrizes de insuficiência cardíaca uma definição clara dos critérios diagnósticos da SCRA. O critério diagnóstico mais comumente utilizado é o aumento da creatinina sérica de pelo menos 0,3 mg/dl em relação à basal. Entretanto, existem controvérsias na definição de creatinina basal e de qual deveria ser a creatinina sérica de referência dos pacientes críticos. Esta revisão sistemática sugere que os critérios de SCRA devem ser revistos para que se inclua o diagnóstico de SCRA na admissão hospitalar. A creatinina sérica de referência deve refletir a função renal basal antes do início da injúria renal aguda.

Background The role of Ser49Gly beta1-adrenergic receptor genetic polymorphism (ADBR1-GP-Ser49Gly) as a predictor of death in heart failure (HF) is not established for the Brazilian population. Objectives To evaluate the association between ADBR1-GP-Ser49Gly and clinical outcomes in individuals with HF with reduced ejection fraction. Methods Secondary analysis of medical records of 178 patients and genotypes of GPRß1-Ser49Gly variants, classified as Ser-Ser, Ser-Gly and Gly-Gly. To evaluate their association with clinical outcome. A significance level of 5% was adopted. Results Cohort means were: clinical follow-up 6.7 years, age 63.5 years, 64.6% of men and 55.1% of whites. HF etiologies were predominantly ischemic (31.5%), idiopathic (23.6%) and hypertensive (15.7%). The genetic profile was distributed as follows: 122 Ser-Ser (68.5%), 52 Ser-Gly (28.7%) and 5 Gly-Gly (2.8%). There was a significant association between these genotypes and mean NYHA functional class at the end of follow-up (p = 0.014) with Gly-Gly being associated with less advanced NYHA. In relation to the clinical outcomes, there was a significant association (p = 0.026) between mortality and GPRß1-Ser49Gly: the number of deaths in patients with Ser-Gly (12) or Gly-Gly (1) was lower than in those with Ser-Ser (54). The Gly allele had an independent protective effect maintained after multivariate analysis and was associated with a reduction of 63% in the risk of death (p = 0.03; Odds Ratio 0.37 - CI 0.15-0.91). Conclusion The presence of ß1-AR-GP Gly-Gly was associated with better clinical outcome evaluated by NYHA functional class and was a predictor of lower risk of mortality, regardless of other factors, in a 6.7-year of follow-up.

Resumo Fundamento O papel do polimorfismo genético do receptor beta1-adrenérgico Ser49Gly (PG-Rβ1-Ser49Gly) como preditor de eventos na insuficiência cardíaca (IC) não está definido para a população brasileira. Objetivos Avaliar a relação entre PG-Rβ1-Ser49Gly e desfechos clínicos em indivíduos com IC com fração de ejeção reduzida. Métodos Análise secundária de prontuários de 178 pacientes e identificação das variantes do PG-Rβ1-Ser49Gly, classificadas como Ser-Ser, Ser-Gly e Gly-Gly. Avaliar sua relação com evolução clínica. Foi adotado nível de significância de 5%. Resultados As médias da coorte foram: seguimento clínico, 6,7 anos; idade, 64,4 anos; 63,5% de homens e 55,1% brancos. A etiologia da IC foi predominantemente isquêmica (31,5%), idiopática (23,6%) e hipertensiva (15,7%). O perfil genético teve a seguinte distribuição: 122 Ser-Ser (68,5%), 52 Ser-Gly (28,7%), e 5 Gly-Gly (2,8%). Houve relação significativa entre esses genótipos e a classe funcional da New York Heart Association (NYHA) ao final do acompanhamento (p = 0,014) com o Gly-Gly associado a NYHA menos avançada. Com relação aos desfechos clínicos, houve associação significativa (p = 0,026) entre mortalidade e PG-Rβ1-Ser49Gly: o número de óbitos em pacientes com Ser-Gly (12) ou Gly-Gly (1) foi menor que com Ser-Ser (54). O alelo Gly teve um efeito protetor independente mantido após análise multivariada e foi associado à redução na chance de óbito de 63% (p = 0,03; odds ratio 0,37 - IC 0,15 a 0,91). Conclusão A presença do PG-Rβ1 Gly-Gly associou-se a melhor evolução clínica avaliada pela classe funcional da NYHA e foi preditor de menor risco de mortalidade, independentemente de outros fatores, em seguimento de 6,7 anos.

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is associated with sudden death (SD). Myocardial fibrosis is reportedly correlated with SD. OBJECTIVE: We performed a systematic review with meta-analysis, updating the risk markers (RMs) in HCM emphasizing myocardial fibrosis. METHODS: We reviewed HCM studies that addressed severe arrhythmic outcomes and the certain RMs: SD family history, severe ventricular hypertrophy, unexplained syncope, non-sustained ventricular tachycardia (NSVT) on 24-hour Holter monitoring, abnormal blood pressure response to exercise (ABPRE), myocardial fibrosis and left ventricular outflow tract obstruction (LVOTO) in the MEDLINE, LILACS, and SciELO databases. We used relative risks (RRs) as an effect measure and random models for the analysis. The level of significance was set at p < 0.05. RESULTS: Twenty-one studies were selected (14,901 patients aged 45 ± 16 years; men, 62.8%). Myocardial fibrosis was the major RISK MARKER (RR, 3.43; 95% CI, 1.95-6.03). The other RMs, except for LVOTO, were also predictors: SD family history (RR, 1.75; 95% CI, 1.39-2.20), severe ventricular hypertrophy (RR, 1.86; 95% CI, 1.26-2.74), unexplained syncope (RR, 2.27; 95% CI, 1.69-3.07), NSVT (RR, 2.79; 95% CI, 2.29-3.41), and ABPRE (RR, 1.53; 95% CI, 1.12-2.08). CONCLUSIONS: We confirmed the association of myocardial fibrosis and other RMs with severe arrhythmic outcomes in HCM and emphasize the need for new prediction models in managing these patients.
