BackgroundHeart failure (HF) is one of the leading causes of hospitalization in adults in Brazil. However, most of the available data is limited to unicenter registries. The BREATHE registry is the first to include a large sample of hospitalized patients with decompensated HF from different regions in Brazil.ObjectiveDescribe the clinical characteristics, treatment and prognosis of hospitalized patients admitted with acute HF.MethodsObservational registry study with longitudinal follow-up. The eligibility criteria included patients older than 18 years with a definitive diagnosis of HF, admitted to public or private hospitals. Assessed outcomes included the causes of decompensation, use of medications, care quality indicators, hemodynamic profile and intrahospital events.ResultsA total of 1,263 patients (64±16 years, 60% women) were included from 51 centers from different regions in Brazil. The most common comorbidities were hypertension (70.8%), dyslipidemia (36.7%) and diabetes (34%). Around 40% of the patients had normal left ventricular systolic function and most were admitted with a wet-warm clinical-hemodynamic profile. Vasodilators and intravenous inotropes were used in less than 15% of the studied cohort. Care quality indicators based on hospital discharge recommendations were reached in less than 65% of the patients. Intrahospital mortality affected 12.6% of all patients included.ConclusionThe BREATHE study demonstrated the high intrahospital mortality of patients admitted with acute HF in Brazil, in addition to the low rate of prescription of drugs based on evidence.
Aims Exhaled breath acetone (EBA) has been described as a new biomarker of heart failure (HF) diagnosis. EBA concentration increases according to severity of HF and is associated with poor prognosis, especially in acute decompensated HF. However, there are no data on chronic HF patients. The aim is to evaluate the role of EBA for predicting cardiac and overall mortality in chronic HF patients. Methods and results In GENIUS-HF cohort, chronic patients were enrolled between August 2012 and December 2014. All patients had left ventricular ejection fraction ≤ 50%, and the diagnosis was established according to Framingham criteria. After consent, patients were submitted to clinical evaluation and exhaled breath collection. EBA identification and quantitative determination were done by spectrophotometry. The clinical characteristics associated with acetone were identified. All participants were followed for 18 months to assess cardiac and overall mortality. Around 700 participants were enrolled in the current analysis. Patients were 55.4 ± 12.2 years old, 67.6% male patients, and 81% New York Heart Association I/II with left ventricular ejection fraction of 32 ± 8.6%. EBA median concentration was 0.6 (0.3-1.2) ug/L. Acetone levels increased with the number of symptoms of HF and were associated with right HF signs/symptoms and liver biochemical changes. EBA at highest quartile (EBA > 1.2ug/L) was associated with a significantly worse prognosis (log rank test, P < 0.001). Cox proportional multivariable regression model revealed that EBA > 1.20ug/L was an independent predictor of cardiac (P = 0.011) and overall (P = 0.010) mortality in our population. Conclusions This study shows that EBA levels reflect clinical HF features, especially right HF signs/symptoms. EBA is an independent predictor of cardiac and overall mortality in chronic HF patients.
Fundamento: Existem grandes oportunidades de melhoria da qualidade do cuidado cardiovascular em países em desenvolvimento por meio da implementação de um programa de qualidade. Objetivo: Avaliar o efeito de um programa de Boas Práticas em Cardiologia (BPC) nos indicadores de desempenho e desfechos clínicos dos pacientes relacionados à insuficiência cardíaca, fibrilação atrial e síndromes coronarianas agudas em um subconjunto de hospitais públicos brasileiros. Métodos: O programa Boas Práticas em Cardiologia (BPC) foi adaptado do programa Get With The Guidelines (GWTG) da American Heart Association (AHA) para ser utilizado no Brasil. O programa está sendo iniciado em três domínios de cuidado simultaneamente (síndrome coronariana aguda, fibrilação atrial e insuficiência cardíaca), o que consiste em uma abordagem nunca testada no GWTG. Existem seis eixos de intervenções utilizadas pela literatura sobre tradução do conhecimento que abordará barreiras locais identificadas por meio de entrevistas estruturadas e reuniões regulares para auditoria e feedback. Planeja-se incluir no mínimo 10 hospitais e 1500 pacientes por doença cardíaca. O desfecho primário inclui as taxas de adesão às medidas de cuidado recomendadas pelas diretrizes. Desfechos secundários incluem o efeito do programa sobre o tempo de internação, mortalidade global e específica, taxas de readmissão, qualidade de vida, percepção do paciente sobre saúde e adesão dos pacientes às intervenções prescritas. Resultados: Espera-se, nos hospitais participantes, uma melhoria e a manutenção das taxas de adesão as recomendações baseadas em evidência e dos desfechos dos pacientes. Este é o primeiro programa em melhoria da qualidade a ser realizado na América do Sul, que fornecerá informações importantes de como programas de sucesso originados em países desenvolvidos como os Estados Unidos podem ser adaptados às necessidades de países com economias em desenvolvimento como o Brasil. Um programa bem sucedido dará informações valiosas para o desenvolvimento de programas de melhoria da qualidade em outros países em desenvolvimento. Conclusões: Este estudo de mundo real proverá informações para a avaliação e aumento da adesão às diretrizes de cardiologia no Brasil, bem como a melhora dos processos assistenciais.
