Abstract	Introduction: Preoperatively elevated serum creatinine (SCr) is considered an independent risk factor for morbidity and mortality after cardiac surgery. The aim of this study was to apply the Kidney Disease Improving Global Outcomes classification for acute kidney injury in a population of patients with preoperatively elevated serum creatinine who underwent cardiac surgery (coronary artery bypass grafting or cardiac valve surgery) and to evaluate the acute worsening of renal function as a predictor of 30-day mortality. Methods: This was a single-center retrospective study that included patients from the Postoperative Cardiac Surgery Intensive Care Unit of the Hospital de Base, São José do Rio Preto Medical School. Demographics, type of surgery, laboratory data and pre, peri and postoperative data were obtained from a prospectively collected database. From January 2003 to June 2013, 2,878 patients underwent cardiac surgery, either coronary artery bypass grafting or cardiac valve surgery, at the Hospital de Base of São José do Rio Preto Medical School. Out of those, 918 showed elevated preoperative serum creatinine, with SCr > 1.30 mg/dL for men and > 1.00 mg/dL for women. Five hundred and forty nine patients (60%) undergoing coronary artery bypass grafting and 369 patients (40%) undergoing cardiac valve surgery. A Multivariate Cox Proportional Hazard Model (stepwise) was used to assess the relationship between AKI and mortality at 30 days. Results: Out of the 918 patients studied, 391 (43%) had postoperative AKI: 318 (35%) had Kidney Disease Improving Global Outcomes stage 1, 27 (2.9%) had Kidney Disease Improving Global Outcomes stage 2, and 46 (5.0%) had Kidney Disease Improving Global Outcomes stage 3. Patients in every stage of acute kidney injury showed progressive increase in EuroSCORE values, 30-day mortality ratescardiopulmonary bypass duration, and intensive care length of stay. Among patients classified as Kidney Disease Improving Global Outcomes stage 3, 76% required dialysis with a 30-day mortality of 66%. The Cox proportional hazards model showed that the hazard ratio for 30-day mortality was 4.8 for Kidney Disease Improving Global Outcomes stage 1 patients, 13.5 for Kidney Disease Improving Global Outcomes stage 2 patients, and 20.8 for Kidney Disease Improving Global Outcomes stage 3 patients (P<0.001 for all). Subgroup analyses (coronary artery bypass grafting and cardiac valve surgery) had similar results. Conclusion: In this population, acute kidney injury based on the Kidney Disease Improving Global Outcomes criteria was a powerful predictor of 30-day mortality in patients with elevated preoperative serum creatinine who underwent cardiac surgery (coronary artery bypass grafting or cardiac valve surgery).

Abstract	OBJECTIVE: We evaluated patients underwent cardiac valve surgery in the presence of infective endocarditis in an attempt to identify independent predictors of 30-day mortality. METHODS: We evaluated 837 consecutive patients underwent cardiac valve surgery from January 2003 to May 2010 in a tertiary hospital in São José do Rio Preto, São Paulo (SP), Brazil. The study group comprised patients who underwent intervention in the presence of infective endocarditis and was compared to the control group (without infective endocarditis), evaluating perioperative clinical outcomes and 30-day all cause mortality. RESULTS: In our series, 64 patients (8%) underwent cardiac valve surgery in the presence of infective endocarditis, and 37.5% of them had surgical intervention in multiple valves. The study group had prolonged ICU length of stay (16%), greater need for dialysis (9%) and higher 30-day mortality (17%) compared to the control group (7%, P=0.020; 2%, P=0.002 and 9%, P=0.038; respectively). In a Cox regression analysis, age (P = 0.007), acute kidney injury (P = 0.004), dialysis (P = 0.026), redo surgery (P = 0.026), re-exploration for bleeding (P = 0.013), tracheal reintubation (P <0.001) and type I neurological injury (P <0.001) were identified as independent predictors for death. Although the manifestation of infective endocarditis influenced on mortality in univariate analysis, multivariate Cox regression analysis did not confirm such variable as an independent predictor of death. CONCLUSION: Age and perioperative complications stand out as predictors of hospital mortality in Brazilian population. Cardiac valve surgery in the presence of active infective endocarditis was not confirmed itself as an independent predictor of 30-day mortality. OBJETIVO: Avaliamos pacientes submetidos à cirurgia valvar em vigência de endocardite infecciosa na tentativa de identificar preditores independentes de mortalidade intrahospitalar em 30 dias. MÉTODOS: Foram avaliados 837 pacientes consecutivamente submetidos à cirurgia valvar, no período de janeiro de 2003 a maio de 2010, em um hospital terciário de São José do Rio Preto, SP, Brasil. O Grupo de Estudo compreendeu indivíduos submetidos à intervenção em vigência de endocardite infecciosa e foi comparado ao Grupo Controle, considerando complicações clínicas perioperatórias e óbito por todas as causas em 30 dias. RESULTADOS: Em nossa casuística, 64 (8%) pacientes foram submetidos à cirurgia valvar em vigência de endocardite infecciosa, sendo 37,5% deles com indicação de intervenção cirúrgica em múltiplas valvas. O Grupo de Estudo apresentou maior permanência em Unidade de Terapia Intensiva (16%), necessidade de diálise (9%) e maior mortalidade em 30 dias (17%) comparado ao Grupo Controle (7%, P=0,020; 2%, P=0,002 e 9%, P=0,038; respectivamente). A análise de regressão de Cox confirmou idade (P=0,007), lesão renal aguda (P=0,004), diálise (P=0,026), reoperação (P=0,026), reintervenção por sangramento (P=0,013), reintubação orotraqueal (P<0,001) e lesão neurológica tipo I (P<0,001) como preditores independentes para óbito. Embora a manifestação de endocardite infecciosa influencie na mortalidade na análise univariada, a regressão de Cox não confirmou tal variável como preditor independente de óbito em nossa casuística. CONCLUSÃO: Idade e complicações perioperatórias destacam-se como preditores de mortalidade hospitalar em população brasileira. Cirurgia valvar em vigência de infecção ativa não se confirma como preditor independente de óbito nesta casuística.

Abstract	OBJETIVO: Comparar o desmame da ventilação mecânica realizado segundo a aplicação de protocolo baseado no teste de respiração espontânea e o mesmo procedimento realizado sem padronização, em pacientes cardiopatas. MÉTODOS: Estudo prospectivo, aberto e randomizado. Em 2006, 36 pacientes em ventilação mecânica há mais de 24 horas foram randomizados em dois grupos: grupo controle: 18 pacientes foram submetidos ao desmame da ventilação mecânica de acordo com os procedimentos adotados pela equipe multiprofissional e grupo experimental: 18 pacientes foram submetidos ao desmame de acordo com protocolo previamente estabelecido. RESULTADOS: Os pacientes do grupo controle iniciaram o desmame precocemente em relação ao grupo experimental (74,7 ± 14,7 horas vs. 185,7 ± 22,9 horas; P=0,0004), Porém, após os pacientes do grupo experimental estarem aptos ao desmame, este foi realizado em um tempo mais curto em relação ao grupo controle (149,1 ± 3,6 min vs. 4179,1 ± 927,8 min; P < 0,0001) com taxas de reintubação significativamente menores (16,7% vs. 66,7%; P = 0,005). CONCLUSÃO: O uso de um protocolo específico, baseado no Teste de Respiração Espontânea para desmame de ventilação mecânica, em pacientes cardiopatas, teve resultados melhores do que o desmame realizado sem um protocolo padronizado, com menor tempo de desmame e menores taxas de reintubação. OBJECTIVE: To compare mechanical ventilation weaning based on a protocol using the spontaneous breathing trial against mechanical ventilation weaning without a standardized protocol in heart patients. METHODS: Prospective, open, randomized study. In 2006, 36 patients undergoing mechanical ventilation for over 24 hours were randomized into two groups: control group - eighteen patients whose mechanical ventilation weaning was performed according to the different procedures adopted by the multidisciplinary team; and experimental group - eighteen patients weaned according to previously established protocol. RESULTS: Control group patients started the weaning process sooner than experimental group patients (74.7 ± 14.7 hours vs. 185.7 ± 22.9 hours, P=0.0004). However, after the experimental group patients were ready for weaning, the extubation was carried out more rapidly than in the control group (149.1 ± 3.6 min vs. 4179.1 ± 927.8 min, P < 0.0001) with significantly lower reintubation rates (16.7% vs. 66.7%, P = 0.005). CONCLUSION: The use of a specific protocol based on the spontaneous breathing trial for mechanical ventilation weaning in heart patients had better outcomes than weaning carried out without a standardized protocol, with shorter weaning times and lower reintubation rates.

Abstract	Homem, sexagenário, deu entrada na emergência com dor torácica duvidosa e lipotímia. Investigado e estratificado, teve eletrocardiogramas e marcadores séricos de injúria miocárdica seriados negativos para isquemia miocárdica, e teste ergométrico sem critérios para isquemia miocárdica. Contudo, apresentou morte súbita presenciada dentro do hospital enquanto fazia uso da monitorização eletrocardiográfica contínua com o holter, que evidenciou, em seus traçados, infarto agudo do miocárdico complicado com arritmia ventricular complexa (taquicardia e fibrilação ventricular), que culminou em morte refratária às manobras de reanimação cardio-respiratória. A sexagenarian man sought the emergency unit complaining of dubious chest pain and lipothymia. He was investigated and stratified. His serial electrocardiograms and serum markers for myocardial injury were negative for myocardial ischemia, as was his exercise test. However, the patient died suddenly inside the hospital while under continuous electrocardiographic Holter monitoring, which evidenced acute myocardial infarction complicated by complex ventricular arrhythmia (ventricular tachycardia and fibrillation), which culminated in death refractory to the cardiopulmonary resuscitation maneuvers.

Abstract	A sífilis é uma doença infecciosa que se desenvolve em estágios e pode acometer o sistema cardiovascular e neurológico. Em 30% dos pacientes não tratados, a sífilis desenvolve sua forma terciária. Relatamos o caso de um homem de 46 anos, admitido por edema pulmonar agudo por cardiopatia isquêmica com bloqueio completo do ramo esquerdo, submetido a terapia fibrinolítica com sucesso. Angiografia coronária mostrou lesão ostial de 90% na artéria coronária esquerda e oclusão do óstio da artéria coronária direita. Os títulos de VDRL foram de 1/128. O paciente foi submetido a revascularização do miocárdio e recebeu alta após tratamento antibiótico com penicilina cristalina. Syphilis is an infectious disease occurring through a series of frequently overlapping stages. It can impair the cardiovascular and neurological system. In 30% of the non treated patients, syphilis develops your tertiary form. We report a case of a 46-year-old male patient admitted due to edema pulmonary and acute coronary syndrome with left bundle branch block, submitted to fibrinolytic therapy successfully. Coronary angiography showed a 90% ostial lesion of left main coronary artery and occlusion of the right coronary artery ostium. VDRL was titrated to 1/128. The patient was undergone to CABG and was discharged after treatment with crystalline penicillin.

Abstract	OBJETIVO: Avaliar o tempo para a estabilização da placa aterosclerótica nas síndromes coronarianas agudas (SCA) utilizando-se marcadores inflamatórios. MÉTODOS: Estudo prospectivo, quarenta pacientes com SCA sem supradesnivelamento de ST versus quarenta indivíduos sem doença coronariana. Proteína C-reativa (PCR), fibrinogênio, fator VIIIc, interleucina-6 e TNF (fator de necrose tumoral)-alfa foram coletados na internação, na alta hospitalar e após três e seis meses. RESULTADOS: Comparada ao controle, a PCR foi significativamente maior na internação e na alta, mas não após três e seis meses. Os níveis de fibrinogênio não apresentaram variações, exceto aos seis meses, quando foi significativamente menor que o controle. O fator VIIIc não diferiu do controle na internação, mas foi significativamente maior na alta, e sem diferenças aos três e seis meses. A IL-6 foi significativamente maior que o controle em todos os períodos. Entretanto, houve queda significativa dos seus níveis entre a alta e três meses. O TNF-alfa não foi significativamente diferente do controle em nenhum momento. Somente a IL-6 se correlacionou significativa e independentemente com eventos cardiovasculares futuros. CONCLUSÃO: Quanto a PCR e fator VIIIc, sugere-se estabilização da placa em até três meses; a análise da IL-6 sugere estabilização a partir do terceiro mês, apesar de permanecer elevada em relação ao controle em até seis meses. Apenas a IL-6 mostrou valor prognóstico de eventos futuros em um ano. OBJECTIVE: To evaluate the length of time required for atherosclerotic plaque stabilization in acute coronary syndromes (ACS), using inflammatory markers. METHODS: In this prospective study, C-reactive protein (CRP), fibrinogen, factor VIIIc, interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) levels were measured on admission, at discharge, and three and six months post-discharge in 40 patients with non-ST-segment elevation ACS (NSTE-ACS) and 40 healthy subjects. RESULTS: C-reactive protein levels were significantly higher on admission and at discharge, but not at three and six months post-discharge, compared with the control group. Fibrinogen levels remained unchanged, except at six months, when they were significantly lower than in the control group. Factor VIII-c did not differ from that of the control group on admission, but it was significantly higher at discharge, with no differences at three and six months. Interleukin-6 levels were significantly higher than in the control group in all time points. However, they declined significantly between discharge and three months. In no time point was TNF-alpha significantly different from that of the control group. Only IL-6 correlated significantly and independently with future cardiovascular events. CONCLUSION: With respect to CRP and factor VIIIc, plaque stabilization is suggested in up to three months; IL-6 analysis suggests stabilization as from the third month, although it remained higher than that of the control group for up to six months. Only IL-6 showed prognostic value for further events within a year.

Abstract	FUNDAMENTO: Vários agentes infecciosos foram investigados desde que se demonstrou a associação entre infecção e aterosclerose, porém os resultados desses estudos são conflitantes. OBJETIVO: Testar a associação entre títulos séricos de anticorpos anti-Chlamydia e anti-Mycoplasma em diferentes formas de síndromes coronarianas agudas (SCA). MÉTODOS: Cento e vinte e seis pacientes foram divididos em quatro grupos: SCA com elevação do segmento ST (32 pacientes), SCA sem elevação do segmento ST (30 pacientes), doença arterial coronariana crônica (30 pacientes) e doadores de sangue sem doença coronariana conhecida (34 pacientes - grupo-controle). Nos primeiros dois grupos, amostras de soro foram coletadas na admissão (primeiras 24 horas de hospitalização) e após 6 meses de seguimento. Nos outros dois grupos, colheu-se apenas uma amostra basal. Em todas as amostras, anticorpos IgG anti-Chlamydia e anti-Mycoplasma foram dosados por imunofluorescência indireta. RESULTADOS: Diferenças significativas foram observadas entre a medida basal e após 6 meses de seguimento nos pacientes com infarto do miocárdio com elevação do segmento ST, tanto para Chlamydia (650±115,7 vs. 307±47,5, p = 0,0001) quanto para Mycoplasma (36,5±5,0 vs. 21,5±3,5, p = 0,0004). Os grupos com SCA tiveram níveis séricos de anticorpos anti-Chlamydia e anti-Mycoplasma mais altos na dosagem basal, em relação aos pacientes com doença arterial coronariana crônica e grupo-controle, mas as diferenças obtidas não tiveram significância estatística. CONCLUSÃO: O presente estudo mostrou associação entre os títulos de anticorpos anti-Chlamydia e anti-Mycoplasma na fase aguda dos pacientes com angina instável ou infarto do miocárdio. FUNDAMENTO: Se han investigado diversos agentes infecciosos desde que se evidenció la asociación entre infección y aterosclerosis, sin embargo esos estudios ofrecen resultados conflictivos. OBJETIVO: Probar la asociación entre títulos séricos de anticuerpos anti-Chlamydia y anti-Mycoplasma en diferentes formas de síndromes coronarios agudos (SCA). MÉTODOS: Se dividieron a 126 pacientes en 4 grupos: SCA con elevación del segmento ST (32 pacientes), SCA sin elevación del segmento ST (30 pacientes), enfermedad arterial coronaria crónica (30 pacientes) y donadores de sangre sin enfermedad coronaria conocida (34 pacientes - grupo-control). En los primeros dos grupos, muestras de suero se colectaron al ingreso (primeras 24 horas de hospitalización) y tras 6 meses de seguimiento. En los otros dos grupos, se colectó solamente una muestra basal. En todas las muestras, se dosificaron anticuerpos IgG anti-Chlamydia y anti-Mycoplasma por inmunofluorescencia indirecta. RESULTADOS: Se observaron diferencias significativas entre la medida basal y tras 6 meses de seguimiento en los pacientes con infarto de miocardio con elevación del segmento ST, tanto para Chlamydia (650±115,7 vs 307±47,5, p = 0,0001) como para Mycoplasma (36,5±5,0 vs 21,5±3,5, p = 0,0004). Los grupos con SCA tuvieron niveles séricos de anticuerpos anti-Chlamydia y anti-Mycoplasma más altos en la dosificación basal, con relación a los pacientes con enfermedad arterial coronaria crónica y grupo-control, sin embargo las diferencias obtenidas no tuvieron significancia estadística. CONCLUSIÓN: El presente estudio reveló asociación entre los títulos de anticuerpos anti-Chlamydia y anti-Mycoplasma en la fase aguda de los pacientes con angina inestable o infarto de miocardio. BACKGROUND: Several infectious agents have been investigated since the association between atherosclerosis and infection was demonstrated; however, the results of these studies are contradictory. OBJECTIVE: To test the association between serum titers of anti-Chlamydia and anti-Mycoplasma antibodies in different forms of acute coronary syndromes (ACS). METHODS: One hundred and twenty-six patients were divided in 4 groups: ACS with ST- segment elevation (32 patients), ACS without ST-segment elevation (30 patients), chronic coronary artery disease (30 patients) and blood donors without known coronary disease (34 patients - control group). In the two first groups, serum samples were collected at hospital admission (first 24 hours of hospitalization) and after a 6-month follow-up. In the other two groups, only a basal sample was collected. Anti-Chlamydia and anti-Mycoplasma antibodies were measured by indirect immunofluorescence in all samples. RESULTS: Significant differences were observed between the basal sample and the one measured after a 6-month follow-up in patients with myocardial infarction with ST-segment elevation for Chlamydia (650±115.7 versus 307±47.5, p=0.0001) as well as Mycoplasma (36.5±5.0 versus 21.5±3.5, p=0.0004). The groups with ACS had higher anti-Chlamydia and anti-Mycoplasma serum antibody levels in the basal measurement, when compared to the patients with chronic coronary disease and the control group, but the differences were not statistically significant. CONCLUSION: The present study showed an association between the serum titers of anti-Chlamydia and anti-Mycoplasma antibodies in the acute phase of patients with unstable angina or myocardial infarction.

Abstract	OBJETIVO: Realizar levantamento de fatores de risco para aterosclerose na população > ou = 20 anos de São José do Rio Preto, e comparar os dados obtidos com os coletados, em levantamento similar, em 1991. MÉDOTOS: Pesquisa quantitativa com amostragem estratificada por sexo e idade. Os entrevistados (646 indivíduos, 303 homens) foram abordados em Postos de Saúde e outros pontos de afluxo da população, distribuídos por zona geográfica e por classe social dos bairros. A margem de erro foi de 4%, e o intervalo de confiança (IC) de 95%. RESULTADOS: A) Níveis médios de HDL-colesterol (apenas em 1997): homens 43,7±15mg/dL, mulheres 49,6±13,5mg/dL (p<0,001, 95% IC 3,7 a 8,1); B) níveis médios de colesterol total em 1991 vs 1997: população global 192,5±48,9mg/dL vs 190,5±42,5mg/dL (p=NS); homens 187,6±53,3 vs 190,5±42,5mg/dL (p=NS); mulheres 196,8±40mg/dL vs 187,6±37,8mg/dL (p=0,008, 95% IC 2,4 a 15,9). C) Em análise de regressão, as variáveis que se correlacionaram significativamente com níveis de colesterol, em ambas as pesquisas, foram: idade (p<0,001), pressão arterial sistólica (p<0,001) e diastólica (p<0,001), dieta (p<0,001). Sexo feminino correlacionou-se apenas em 1991 (p=0,011) e sedentarismo apenas em 1997 (p=0,014). CONCLUSÃO: Os níveis de colesterol na população adulta de São José do Rio Preto são bastante aceitáveis, sendo que no sexo feminino diminuíram, de maneira significativa, na pesquisa atual, em relação à realizada em 1991. PURPOSE: To develop a survey about risk factors for atherosclerosis in a > or = 20-year-old population from São José do Rio Preto, and compare the results with those obtained in a similar survey in 1991. METHODS: Quantitative survey with sample stratified by sex and age. The individuals (a total of 646, 303 men) where contacted in outpatient facilities from the Health Secretary and other populated sites, distributed by geographic zone and social class of different neighborhoods. The standard error of the survey was 4%, and the confidence interval was 95%. RESULTS: A) Mean HDL-cholesterol (only in 1997): male gender 43.7±15mg/dL, female gender 49.6±13.5mg/dL (p<0.001, 95% CI 3.7 a 8.1). B) Mean total cholesterol in 1991 vs 1997: for the global population 192.5±48.9mg/dL vs 190.5±42.5mg/dL (p=NS); for men 187.6±53.3mg/dL vs 190.5±42.5mg/dL (p=NS); for women 196.8±40mg/dL vs 187.6±37.8mg/dL (p=0.008, 95% CI 2.4 a 15.9). C) By regression analysis, the variables that correlated significantly with cholesterol levels, in both surveys, were: age (p<0.001), systolic (p<0.001) and diastolic (p<0.001) arterial pressure, diet (p<0.001). Female gender showed correlation only in the 1991 survey (p=0.011), and sedentarism only in 1997 (p=0.014). CONCLUSION: The mean cholesterol levels in the adult population of São José do Rio Preto are very favorable and, in female gender, showed a significant decrease in the 1997 survey, relatively to the 1991 survey.

Abstract	OBJETIVO: É comum a obtenção de acesso venoso femoral em pacientes submetidos a cirurgia cardíaca em associação ou como alternativa ao acesso superior (veia jugular interna ou veia subclávia). O objetivo deste estudo foi comparar as medidas de pressão venosa central (PVC) em dois sítios diferentes (superior vs. femoral). MÉTODOS: Estudo prospectivo e aberto com 60 pacientes submetidos a cirurgia cardíaca no período de julho a novembro de 2006. Foram obtidas três medidas de cada paciente em cada sítio (admissão, 6 e 12 horas após a cirurgia) em duas inclinações diferentes da cabeceira do leito (zero e 30 graus), totalizando 720 medidas. RESULTADOS: Cinqüenta e cinco por cento dos pacientes foram submetidos a revascularização do miocárdio, 38% a cirurgia valvar e 7% a outras cirurgias. A média de PVC ± desvio padrão (DP) medida no acesso superior foi de 13,0 ± 5,5 mmHg (zero grau) e 13,3 ± 6,1 mmHg (30 graus), enquanto que as medidas no acesso inferior foram 11,1 ± 4,9 mmHg (zero grau) e 13,7 ± 4,6 mmHg (30 graus). A correlação linear (r) entre as medidas nos dois sítios foi de 0,66 (zero grau) e 0,53 (30 graus), ambas com p < 0,0001. CONCLUSÃO: A PVC pode ser medida com acurácia no acesso venoso femoral no pós-operatório imediato de cirurgia cardíaca, com melhor correlação linear obtida com as medidas feitas com a cabeceira do leito posicionada em zero grau. OBJECTIVE: It is common to obtain femoral venous approach in patients undergoing combined heart surgery or as an alternative to superior approach (internal jugular vein or subclavian vein). The aim of this study was to compare the measures of central venous pressure (CVP) at two different sites (superior versus femoral). METHODS: We prospectively and openly allocated 60 patients who underwent heart surgery between July from November 2006. Three measures were obtained from each patient at each site (admission, 6 and 12 hours after surgery) in two different inclinations of the headboard (zero and 30 degrees) totaling 720 measures. RESULTS: Fifty five percent of patients who underwent coronary artery bypass grafting, 38% heart valve surgery and 7% other surgeries. The mean of CVP ± standard deviation (SD) measured in superior approach was 13.0 ± 5.5 mmHg (zero degree) and 13.3 ± 6.1 mmHg (30 degrees) while the measures in inferior approach were 11.1 ± 4.9 mmHg (zero degree) and 13.7 ± 4.6 mmHg (30 degrees). The linear correlation (r) between the measures in both sites was 0.66 (zero degree) and 0.53 (30 degrees), both with p value<0.0001. CONCLUSION: The CVP can be measured with accuracy in the femoral venous approach in the immediate postoperative period of heart surgery with better linear correlation obtained with the measures made with the headboard positioned at zero degree.

Abstract	OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and ...
