Elevada prevalência de Burnout em médicos residentes de um grande Instituto de Cardiologia Brasileiro / High prevalence of burnout in resident physicians of a large Brazilian Institute of Cardiology

INTRODUÇÃO: A residência médica pode estar sujeita a fatores estressores magnificados e poderia aumentar a suscetibilidade à síndrome de exaustão emocional, despersonalização e reduzida realização profissional, conhecida como burnout. OBJETIVO: Determinar a prevalência de burnout e de cada uma de suas dimensões na população de médicos residentes de um dos maiores Institutos especializados de Cardiologia do Brasil. MÉTODOS: Estudo transversal com residentes, realizado em 2017, através da aplicação de um instrumento contendo dois questionários: um com variáveis sociodemográficas e o questionário Maslach Burnout Inventory...(AU)

Implementation of a Regional Network for ST-Segment-Elevation Myocardial Infarction (STEMI) Care and 30-Day Mortality in a Low- to Middle-Income City in Brazil: Findings From Salvador's STEMI Registry (RESISST).

BACKGROUND: Few data exist on regional systems of care for the treatment of ST-segment-elevation myocardial infarction (STEMI) in developing countries. Our objective was to describe temporal trends in 30-day mortality and identify predictors of mortality among STEMI patients enrolled in a prospective registry in Brazil. METHODS AND RESULTS: From January 2011 to June 2013, 520 patients who received initial STEMI care at 23 nonspecialized public health units or hospitals, some of whom were transferred to a public cardiology referral center, were identified through a regional STEMI network supported by telemedicine and the local prehospital emergency medical service. We stratified patients into five 6-month periods based on presentation date. Mean age (±SD) of patients was 62.0 (±12.2) years, and 55.6% were men. The mean Global Registry of Acute Coronary Events (GRACE) score was 145 (±34). Overall mortality at 30 days was 15.0%. Use of dual antiplatelet therapy and statins increased significantly from baseline (January 2011) to period 5 (June 2013): 61.8% to 93.6% (P<0.001) and 60.4% to 79.7% (P<0.001), respectively. Rates of primary reperfusion also increased (29.1%-53.8%; P<0.001), and more patients were transferred to the referral center (44.7%-76.3%; P=0.001). Thirty-day mortality rates decreased from 19.8% to 5.1% (P<0.001). In multivariable analysis, factors independently associated with 30-day mortality were higher GRACE score, history of previous stroke, lack of transfer to the referral center, and lack of use of optimized medical therapy. CONCLUSIONS: Implementation of a regional STEMI system was associated with lower mortality and higher use of evidence-based therapies.

O papel dos métodos diagnósticos na estratificação de risco de morte súbita na doença de Chagas / The role of diagnostic methods in the stratification of risk of sudden death in Chagas disease

A doença de Chagas ainda é uma enfermidade bastante prevalente, principalmente em países subdesenvolvidos (inclusive o Brasil), e acarreta morbimortalidade importante e prejuízo sociais econômicas e para a saúde da população - dentre os quais se encontra a morte súbita. A morte súbita é responsável por cerca de 50% das mortes de causa cardíaca...
