Abstract Background Although there have been significant improvements in the treatment of heart failure (HF) in recent decades, its prognosis remains poor. Although there are many biomarkers that can help predict the prognosis of patients with HF, there is a need for simpler, cheaper, and more easily available biomarkers. Objective To evaluate the predictive value of pan-immune-inflammation value (PIV) in patients with acute decompensated HF. Methods We analyzed 409 patients with HF with reduced ejection fraction who were hospitalized for acute decompensated HF. Patients were divided into 3 groups according to tertiles of PIV: tertile 1 (PIV < 357.25), tertile 2 (PIV ≥ 357.25 and < 834.55), and tertile 3 (PIV ≥ 834.55). P values < 0.05 were considered statistically significant. Kaplan-Meier curves and Cox proportional hazards regression models were used to evaluate the association between PIV and all-cause mortality. The primary outcome was 5-year all-cause mortality, and the secondary outcomes were in-hospital 30 days,, 180-day, and 1-year all-cause mortality. Results We showed that higher PIV value was associated with both primary and secondary outcomes. The Kaplan-Meier curve showed that patients with higher PIV values had an increased risk of short- and long-term all-cause mortality (log-rank p < 0.001). In the multivariate analysis, PIV was identified as an independent predictor of long-term all-cause mortality in patients with acute decompensated HF, and we observed a 1.96-fold increase in the hazard of an event (odds ratio: 1.96, 95% confidence interval: 1.330 to 2.908, p = 0.001). Conclusions Our study showed that the novel biomarker PIV can be used as a predictor of prognosis in patients with acute decompensated HF.

Resumo Fundamento Embora tenha havido melhorias significativas no tratamento da insuficiência cardíaca (IC) nas últimas décadas, seu prognóstico permanece desfavorável. Embora existam muitos biomarcadores que podem ajudar a prever o prognóstico de pacientes com IC, há necessidade de biomarcadores mais simples, menos dispendiosos e mais facilmente disponíveis. Objetivo Avaliar o valor preditivo do valor pan-imune-inflamatório (PIV, do inglês pan-immune-inflammation value) em pacientes com IC agudamente descompensada. Métodos Analisamos 409 pacientes com IC com fração de ejeção reduzida internados por IC aguda descompensada. Os pacientes foram divididos em 3 grupos de acordo com os tercis de PIV: tercil 1 (PIV < 357,25), tercil 2 (PIV ≥ 357,25 e < 834,55) e tercil 3 (PIV ≥ 834,55). Foram considerados estatisticamente significativos valores de p < 0,05. Curvas de Kaplan-Meier e modelos de regressão de riscos proporcionais de Cox foram utilizados para avaliar a associação entre PIV e mortalidade por todas as causas. O desfecho primário foi mortalidade por todas as causas em 5 anos, e o desfecho secundário compreendeu a mortalidade por todas as causas intra-hospitalar em 30 dias, em 180 dias e em 1 ano Resultados Mostramos que valores mais elevados de PIV estavam associados a desfechos primários e secundários. A curva de Kaplan-Meier mostrou que pacientes com valores mais elevados de PIV apresentaram risco aumentado de mortalidade por todas as causas em curto e longo prazo (log-rank p < 0,001). Na análise multivariada, o PIV foi identificado como um preditor independente de mortalidade por todas as causas em longo prazo em pacientes com IC aguda descompensada, e observamos um aumento de 1,96 vezes no risco de um evento (razão de chances: 1,96; intervalo de confiança de 95%: 1,330 a 2,908; p = 0,001). Conclusões Nosso estudo mostrou que o novo biomarcador PIV pode ser usado como preditor de prognóstico em pacientes com IC aguda descompensada.

SUMMARY OBJECTIVE: With the coronavirus disease 2019 (COVID-19) continuing to spread all over the world, although there is no specific treatment until now, hydroxychloroquine and azithromycin have been reported to be effective in recent studies. Although long-term use of hydroxychloroquine and azithromycin has been reported to cause QT prolongation and malign arrhythmia, there is not enough data about the effect of short-term use on arrhythmia. Therefore, this study aims to assess the effect of hydroxychloroquine alone and hydroxychloroquine + azithromycin on corrected QT (QTc). METHODS: A baseline electrocardiogram and on-treatment baseline electrocardiogram were retrospectively collected in COVID-19 patients who received hydroxychloroquine and/or azithromycin. The QTc interval was calculated, and the baseline and peak QTc intervals were compared. In addition, the peak QTc intervals of monotherapy and combination therapy were compared. RESULTS: Of the 155 patients included, 102 (65.8%) patients were using hydroxychloroquine, and 53 (34.2%) patients were using hydroxychloroquine + azithromycin combination. The use of both hydroxychloroquine alone and hydroxychloroquine + azithromycin combined therapy significantly prolonged the QTc, and the QTc interval was significantly longer in patients receiving combination therapy. QTc prolongation caused early termination in both groups, 5 (4.9%) patients in the monotherapy group and 6 (11.3%) patients in the combination therapy group. CONCLUSION: In this study, patients who received hydroxychloroquine for the treatment of COVID-19 were at high risk of QTc prolongation, and concurrent treatment with azithromycin was associated with greater changes in QTc.

Objetivo: Pós-operatório fibrilação atrial é uma complicação comum após a cirurgia cardíaca, com uma incidência tão elevada quanto 20-50%. O aumento da idade está associado com elevação significativa no risco de pós-operatório da fibrilação atrial. Esta complicação comum é associada com taxas de morbidade e mortalidade. O objetivo deste estudo foi avaliar a eficácia do nebivolol na prevenção da fibrilação atrial após cirurgia de revascularização do miocárdio de pacientes acima de 60 anos de idade. Métodos: Neste estudo prospectivo e randomizado, duzentos pacientes candidatos à cirurgia de revascularização do miocárdio foram divididos em dois grupos. O primeiro grupo foi administrado com nebivolol e o segundo grupo, com metoprolol. O tratamento foi iniciado quatro dias antes da cirurgia, e os pacientes foram monitorados para fibrilação atrial até a alta. Quarenta e um pacientes receberam 50 mg de sucinato de metoprolol diário, que foi iniciado, no mínimo, 4 dias antes da cirurgia. Resultados: Os dados demográficos foram semelhantes nos dois grupos. A incidência de fibrilação atrial pós-operatória em ambos os grupos foi semelhante, com nenhuma diferença significativa sendo identificado [n=20 (20%); n=18 (18%), P=0,718; respectivamente]. Não houve mortalidade em ambos os grupos durante o estudo. A necessidade de agente inotrópico em UTI foi semelhante nos dois grupos [n=12 pessoas (12%), n=18 (18%), P=0,32]. Conclusão: Nós comparamos a eficácia do nebivolol e metoprolol na diminuição da incidência de fibrilação atrial no pós-operatório, e verificamos que nebivolol foi tão eficaz como metoprolol na prevenção de fibrilação atrial no pós-operatório em pacientes. Nebivolol pode ser a droga de escolha devido aos seus efeitos, especialmente depois da cirurgia revascularização do miocárdio.

Objective: Postoperative atrial fibrillation is a common complication after cardiac surgery, with an incidence as high as 20-50%. Increased age is associated with a significant increase in postoperative atrial fibrillation risk. This common complication is associated with higher morbidity and mortality rates. The aim of this study was to assess the efficacy of nebivolol in preventing atrial fibrillation following coronary artery bypass surgery in patients over 60 years of age. Methods: In this prospective randomized study, 200 patients who were candidates for elective coronary artery bypass surgery were divided into two groups. The first group was administered with nebivolol and the second group was administered with metoprolol. Treatment was initiated four days prior to surgery, and patients were monitored for atrial fibrillation until discharge. Forty-one patients recieved 50 mg metoprolol succinate daily, which was initiated minimum 4 days before surgery. Results: Demographic data were similar in both groups. The incidence of postoperative atrial fibrillation in both groups was similar, with no significant difference being identified [n=20 (20%); n=18 (18%), P=0.718; respectively]. There were not any mortality at both groups during study. Inotropic agent requirement at ICU was similar for both groups [n=12 (12%), n=18 (18%), P=0.32]. Conclusion: We compared the effectiveness of nebivolol and metoprolol in decreasing the incidence of postoperative atrial fibrillation, and determined that nebivolol was as effective as metoprolol in preventing postoperative atrial fibrillation at patients. Nebivolol may be the drug of choice due to its effects, especially after elective coronary artery bypass surgery.

Apresentamos um caso de reparo bem-sucedido da valva mitral decorrente de endocardite infecciosa ativa. Reparo da valva mitral foi acompanhado de desbridamento da vegetação e do abscesso, ressecção e plastia do folheto mitral posterior, e anuloplastia posterior com pericárdio autólogo. Pós-operatório sem evidências de infecção recorrente, e ecocardiograma demonstrou competência da valva mitral com regurgitação mitral trivial. Concluímos que o reparo valvar é uma escolha viável em caso de endocardite ativa nas crianças.

We present a case of successful repair of the mitral valve for active infective endocarditis. Mitral valve repair was performed through debridement of vegetation and abscess, resection and repair of the posterior mitral leaflet and posterior repair with autologous pericardium. Postoperative period was uneventfully, with no evidence of recurrent infection, and echocardiogram showed mitral valve competence with mild mitral regurgitation. We demonstrate that valve repair is a feasible choice in cases of active endocarditis in children.
