RESUMO

ABSTRACT Objective To evaluate indications, results and strategy of retinal exams requested at Primary Care Units. Methods A retrospective study that analyzed the indications and results of retinal exams, in the modalities clinical dilated fundus exams and color fundus photographs. In the following situations, patients were considered eligible for color fundus photographs if visual acuity was normal and ocular symptoms were absent: diabetes mellitus and/or hypertension, in use of drugs with potential retinal toxicity, diagnosis or suspicion of glaucoma, stable and asymptomatic retinopathies, except myopia greater than -3.00 diopters. Results A total of 1,729 patients were evaluated (66% female, age 63.5±15.5 years), and 1,190 underwent clinical dilated fundus exam and 539 underwent color fundus photographs. Diabetes was present in 32.2%. The main indications were diabetes (23.7%) and glaucoma evaluation (23.5%). In 3.4% of patients there was no apparent indication. The main results were a large cup/disc ratio (30.7%) and diabetic retinopathy (13.2%). Exam was normal in 9.6%, detected peripheral changes in 7% and could not be performed in 1%. Considering patients eligible for fundus photographs (22.4%), more than half underwent clinical dilated fundus exams. Conclusion Regarding exam modality, there were no important differences in the distribution of indications or diagnosis. Color fundus photograph is compatible with telemedicine and more cost-effective, and could be considered the strategy of choice in some scenarios. Since there are no clear guidelines for retinal exams indications or the modality of choice, this study may contribute to such standardization, in order to optimize public health resources.


RESUMO Objetivo Avaliar as indicações, os resultados e a estratégia de exames de retina solicitados em Unidades Básicas de Saúde. Métodos Estudo retrospectivo no qual foram analisados as indicações e os resultados de exames de retina, nas modalidades mapeamento de retina e retinografia. Em casos de boa acuidade visual e sintomas oculares ausentes, foram considerados elegíveis para avaliação por retinografia: pacientes com diabetes mellitus e/ou hipertensão arterial sistêmica, em uso de medicação com potencial toxicidade retiniana, diagnóstico ou suspeita de glaucoma, e retinopatias estáveis e assintomáticas, exceto miopia maior que -3,00 dioptrias. Resultados Foram avaliados 1.729 pacientes (66% do sexo feminino, idade 63,5±15,5 anos). Destes, 1.190 realizaram mapeamento de retina e 539 realizaram retinografia. Diabetes estava presente em 32,2%. As principais indicações para solicitação do exame foram diabetes (23,7%) e investigação de glaucoma (23,5%). Em 3,4%, não havia indicação aparente. Os principais resultados foram aumento da escavação papilar (30,7%) e retinopatia diabética (13,2%). O exame foi normal em 9,6%; detectou alterações periféricas em 7%; e sua realização foi impossível em 1%. Dos pacientes elegíveis para retinografia (22,4%), mais da metade foi submetida ao mapeamento de retina. Conclusão Não houve diferenças importantes nas distribuições de indicações ou diagnósticos em relação à modalidade de exame. A retinografia, compatível com telemedicina e mais custo-efetiva, pode ser considerada a modalidade de escolha em determinadas situações. Na ausência de consenso quanto às indicações para a solicitação de exames da retina ou sua modalidade, este estudo pode contribuir para tal padronização, de modo a otimizar recursos do sistema público de saúde.

RESUMO

OBJECTIVE: We aim to examine the effect of benchmarking on quality-of-care metrics in patients presenting with ST-elevation myocardial infarction (STEMI) through the implementation of the American College of Cardiology (ACC) National Cardiovascular Data Registry (NCDR) ACTION Registry. DESIGN: From January 2005 to December 2017, 712 patients underwent primary percutaneous coronary intervention PCI-499 before NCDR ACTION Registry implementation (prior to 2013) and 213 after implementation. SETTING: STEMI. PARTICIPANTS: 712 patients. INTERVENTION(S): Primary PCI. MAIN OUTCOME MEASURE(S): We examined hospital performance for the quality indicators in processes and outcomes of the management of patients presenting with STEMI. Outcome measures include door-to-balloon time (DBT), antiplatelet therapy and anti-ischemic drugs prescribed at discharge from pre-NCDR ACTION Registry to post-implementation. RESULTS: There was improvement in DBT, decreasing from 94 min in 2012 (before NCDR adoption) to reach a median of 47 min in 2017 (Ptrend < 0.001). The percentage of cases with the optimal DBT of < 90 min increased from 55.8% before to 90.1% after the implementation of the NCDR ACTION Registry (Ptrend < 0.001). The rate of aspirin (90.3-100%, P < 0.001), P2Y12 inhibitor (70.1-78.4%, P = 0.02), beta-blocker (76.8-100%, P < 0.001) and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (60.1-99.5%, P < 0.001) prescribed at discharge increased from pre-NCDR ACTION Registry to post-implementation. Adjusted mortality before and after NCDR ACTION Registry implementation showed significant change (from 9.04 to 5.92%; P = 0.027). CONCLUSIONS: The introduction of the ACC NCDR ACTION Registry led to incremental gains in the quality in STEMI management through the benchmarking of process of care and clinical outcomes, achieving reduced DBT, improving guideline-directed medication adherence and increasing patient safety, treatment efficacy and survival.

RESUMO

OBJECTIVE: To develop and test a beat-to-beat blood pressure monitoring device during coronary angiography, and compare it with invasive blood pressure monitoring. METHODS: Twenty-eight patients with an indication for hemodynamic study were selected for this investigation, and kept in supine position. Before starting the coronary angiography, they were instructed about the use of the left radial bracelet for beat-to-beat blood pressure monitoring. RESULTS: There was a significant difference between the time required for the catheterization laboratory team to acquire the first invasive blood pressure reading and the time to obtain the first beat-to-beat reading (11.1±5.1 and 1.5±1.8, respectively; p<0.0001). The intraclass correlation coefficients (95%CI) of systolic and diastolic blood pressures were 0.897 (0.780-0.952) and 0.876 (0.734-0.942), indicating good reproducibility. CONCLUSION: This study showed the process to develop a beat-to-beat blood pressure monitoring device. When compared to invasive blood pressure monitoring, there were no significant differences between the two methods. This technique may play a promising coadjuvant role when combined with invasive monitoring during coronary angiography procedures.

RESUMO

Introducción y objetivos: El daño renal agudo (DRA) ocurre con frecuencia tras el implante percutáneo de válvula aórtica (TAVI) y se asocia con una mayor mortalidad. Sin embargo, el impacto del DRA en la evolución a largo plazo continúa siendo controvertida. Por dicho motivo se evalúa el impacto del DRA el resultado a corto y largo plazo tras el TAVI usando los criterios Valve Academic Research Consortium 2. Métodos: Se incluyeron 794 pacientes consecutivos con estenosis aórtica grave en un registro multicéntrico brasileño. Para la identificación de los predictores de DRA se utilizó el análisis de regresión logística. La supervivencia a 4 años se determinó mediante las curvas de Kaplan-Meier y para determinar el impacto del DRA en la mortalidad entre los supervivientes a 12 meses se usó un análisis de punto de referencia ajustado. Resultados: La incidencia de DRA tras el TAVI fue del 18%. Los predictores independientes de DRA fueron: edad, diabetes mellitus, hemorragia mayor o amenazante para la vida y la malaposición valvular. El DRA se asoció independientemente con un riesgo mayor de muerte total (HR ajustada = 2,8; IC95%, 2,0-3,9; p < 0,001) y cardiovascular (HR ajustada = 2,9; IC95%, 1,9-4,4; p < 0,001) durante el periodo de seguimiento completo. Sin embargo, cuando se consideró solo los supervivientes a 12 meses, no hubo diferencias en ambos objetivos clínicos (HR ajustada = 1,2; IC95%, 0,5-2,4; p = 0,71, y HR = 0,7; IC95%, 0,2-2,1; p = 0,57, respectivamente). Conclusiones: El DRA es una complicación frecuente tras el TAVI. La edad avanzada, la diabetes, la hemorragia mayor o amenazante para la vida y la malaposición valvular eran factores predictivos de DRA. El DRA se asoció con el pronóstico a corto y largo plazo, sin embargo, el impacto del DRA sobre la mortalidad se limitó al primer año tras el TAVI


Introduction and objectives: Acute kidney injury (AKI) is frequently observed after transcatheter aortic valve implantation (TAVI) and is associated with higher mortality. However, the impact of AKI on long-term outcomes remains controversial. Therefore, we sought to evaluate the impact of AKI on short- and long-term outcomes following TAVI using the Valve Academic Research Consortium 2 criteria. Methods: Consecutive patients (n = 794) with severe aortic stenosis who underwent TAVI were included in a multicenter Brazilian registry. Logistic regression analysis was used to identify predictors of AKI. Four-year outcomes were determined as Kaplan-Meier survival curves, and an adjusted landmark analysis was used to test the impact of AKI on mortality among survivors at 12 months. Results: The incidence of AKI after TAVI was 18%. Independent predictors of AKI were age, diabetes mellitus, major or life-threatening bleeding and valve malpositioning. Acute kidney injury was independently associated with higher risk of all-cause death (adjusted HR, 2.8; 95%CI, 2.0-3.9; P < .001) and cardiovascular mortality (adjusted HR, 2.9; 95%CI, 1.9-4.4; P < .001) over the entire follow-up period. However, when considering only survivors at 12 months, there was no difference in both clinical endpoints (adjusted HR, 1.2; 95%CI, 0.5-2.4; P = .71, and HR, 0.7; 95%CI, 0.2-2.1; P = .57, respectively). Conclusions: Acute kidney injury is a frequent complication after TAVI. Older age, diabetes, major or life-threatening bleeding, and valve malpositioning were independent predictors of AKI. Acute kidney injury is associated with worse short- and long-term outcomes. However, the major impact of AKI on mortality is limited to the first year after TAVI

RESUMO Objetivo Desenvolver e validar um equipamento para monitorização de pressão arterial batimento a batimento, durante a realização de coronariografia, e comparar com as medidas de pressão arterial invasiva obtidas. Métodos Foram selecionados 28 pacientes com indicação de estudo hemodinâmico, que permaneceram em decúbito dorsal horizontal e, antes do início da coronariografia, foram orientados quanto ao uso da pulseira radial esquerda para monitorização da pressão arterial batimento a batimento. Resultados Houve diferença significativa entre o tempo necessário para a equipe de hemodinâmica adquirir a primeira medida da pressão arterial invasiva e o tempo da primeira medida da pressão arterial batimento a batimento (11,1±5,1 e 1,5±1,8, respectivamente; p<0,0001). Os coeficientes de correlação intraclasse (IC95%) da pressão arterial sistólica e da diastólica foram 0,897 (0,780-0,952) e 0,876 (0,734-0,942), indicando boa reprodutibilidade. Conclusão Este estudo demonstrou o processo de desenvolvimento de um equipamento para avaliação da pressão arterial batimento a batimento. Quando comparado com a pressão arterial invasiva, não foram encontradas diferenças significativas entre as duas medidas. Essa técnica pode constituir ferramenta coadjuvante promissora, associada à monitorização invasiva, durante procedimentos de coronariografia.

RESUMO

BACKGROUND: Coronary artery calcification (CAC) and atherosclerotic inflammation associate with increased risk of myocardial infarction (MI). Vascular calcification is regulated by osteogenic proteins (OPs). It is unknown whether an association exists between CAC and plasma OPs and if they are affected by atherothrombotic inflammation. We tested the association of osteogenic and inflammatory proteins with CAC and assessed these biomarkers after MI. METHODS: Circulating OPs (osteoprotegerin, RANKL, fetuin-A, Matrix Gla protein [MGP]) and inflammatory proteins (C-reactive protein, oxidized-LDL, tumoral necrosis factor-α, transforming growth factor [TGF]-ß1) were compared between stable patients with CAC (CAC ≥ 100 AU, n = 100) and controls (CAC = 0 AU, n = 30). The association between biomarkers and CAC was tested by multivariate analysis. In patients with MI (n = 40), biomarkers were compared between acute phase and 1-2 months post-MI, using controls as a baseline. RESULTS: MGP and fetuin-A levels were higher within individuals with CAC. Higher levels of MGP and RANKL were associated with CAC (OR 3.12 [95% CI 1.20-8.11], p = 0.02; and OR 1.75 [95% CI 1.04-2.94] respectively, p = 0.035). After MI, C-reactive protein, OPG and oxidized-LDL levels increased in the acute phase, whereas MGP and TGF-ß1 increased 1-2 months post-MI. CONCLUSIONS: Higher MGP and RANKL levels associate with CAC. These findings highlight the potential role of these proteins as modulators and markers of CAC. In addition, the post-MI increase in OPG and MGP, as well as of inflammatory proteins suggest that the regulation of these OPs is affected by atherothrombotic inflammation.

RESUMO

Value-based health care has been touted as the "strategy that will fix healthcare," yet putting this value agenda to work in the real world is not an easy task. Robert Kaplan and colleagues first introduced the concept of a value management office (VMO) that may help to accelerate the dissemination and adoption of this value agenda. In this article, we describe the first known experience of the implementation of a VMO in a Latin American hospital and the main steps we have already taken to accelerate this value agenda at Hospital Israelita Albert Einstein. We faced a number of challenges in implementing the VMO at Einstein, including integration with existing clinical and financial information areas, transition to a standardized outcomes model, adaptation to our "open medical staff" model by connecting the VMO with the Medical Practice Division, and involvement with our physician-led multidisciplinary groups.

RESUMO

BACKGROUND: The perception of cardiovascular (CV) risk is essential for adoption of healthy behaviors. However, subjects underestimate their own risk. HYPOTHESIS: Clinical characteristics might be associated with self-underestimation of CV risk. METHODS: This is a retrospective, cross-sectional study of individuals submitted to routine health evaluation between 2006 and 2012, with calculated lifetime risk score (LRS) indicating intermediate or high risk for CV disease (CVD). Self-perception of risk was compared with LRS. Logistic regression analysis was performed to test the association between clinical characteristics and subjective underestimation of CV risk. RESULTS: Data from 5863 subjects (age 49.4 ± 7.1 years; 19.9% female) were collected for analysis. The LRS indicated an intermediate risk for CVD in 45.7% and a high risk in 54.3% of individuals. The self-perception of CV risk was underestimated compared with the LRS in 4918 (83.9%) subjects. In the adjusted logistic regression model, age (odds ratio [OR]: 1.28, 95% confidence interval [CI]: 1.10-1.47 per 10 years, P = 0.001), smoking (OR: 1.99, 95% CI: 1.40-2.83, P < 0.001), dyslipidemia (OR: 1.21, 95% CI: 1.01-1.46, P = 0.045), physical activity (OR: 1.66, 95% CI: 1.36-2.02, P < 0.001), and use of antihypertensive (OR: 1.49, 95% CI: 1.15-1.92, P = 0.002) and lipid-lowering medications (OR: 2.13, 95% CI: 1.56-2.91, P < 0.001) were associated with higher chance of risk underestimation, whereas higher body mass index (OR: 0.92, 95% CI: 0.90-0.94, P < 0.001), depressive symptoms (OR: 0.46, 95% CI: 0.37-0.57, P < 0.001), and stress (OR: 0.41, 95% CI: 0.33-0.50, P < 0.001) decreased the chance. CONCLUSIONS: Among individuals submitted to routine medical evaluation, aging, smoking, dyslipidemia, physical activity, and use of antihypertensive and lipid-lowering medications were associated with higher chance of CV risk underestimation. Subjects with these characteristics may benefit from a more careful risk orientation.

RESUMO

BACKGROUND: In high-income temperate countries, the number of hospitalizations for heart failure (HF) and acute myocardial infarction (AMI) increases during the winter. This finding has not been fully investigated in low- and middle-income countries with tropical and subtropical climates. We investigated the seasonality of hospitalizations for HF and AMI in Sao Paulo (Brazil), the largest city in Latin America. METHODS: This was a retrospective study using data for 76,474 hospitalizations for HF and 54,561 hospitalizations for AMI obtained from public hospitals, from January 2008 to April 2015. The average number of hospitalizations for HF and AMI per month during winter was compared to each of the other seasons. The autoregressive integrated moving average (ARIMA) model was used to test the association between temperature and hospitalization rates. FINDINGS: The highest average number of hospital admissions for HF and AMI per month occurred during winter, with an increase of up to 30% for HF and 16% for AMI when compared to summer, the season with lowest figures for both diseases (respectively, HF: 996 vs. 767 per month, p<0.001; and AMI: 678 vs. 586 per month, p<0.001). Monthly average temperatures were moderately lower during winter than other seasons and they were not associated with hospitalizations for HF and AMI. INTERPRETATION: The winter season was associated with a greater number of hospitalizations for both HF and AMI. This increase was not associated with seasonal oscillations in temperature, which were modest. Our study suggests that the prevention of cardiovascular disease decompensation should be emphasized during winter even in low to middle-income countries with tropical and subtropical climates.

RESUMO

OBJECTIVES: This study sought to examine long-term outcomes with transcatheter aortic valve replacement (TAVR) in women versus men. BACKGROUND: TAVR is commonly performed in women. Previous studies have shown conflicting results with respect to sex differences in outcomes with TAVR. In addition, short-term outcomes have primarily been reported. METHODS: Electronic search was performed until March 2017 for studies reporting outcomes with TAVR in women versus men. Random effects DerSimonian-Laird risk ratios were calculated. Outcomes included all-cause mortality and major cardiovascular events at short- (30 days) and long-term (>1 year) follow-up. RESULTS: Seventeen studies (8 TAVR registries; 47,188 patients; 49.4% women) were analyzed. Women were older but exhibited fewer comorbidities. At 30 days, women had more bleeding (p < 0.001), vascular complications (p < 0.001), and stroke/transient ischemic attack (p = 0.02), without difference in all-cause (p = 0.19) or cardiovascular mortality (p = 0.91) compared with men. However, female sex was associated with lower all-cause mortality at 1 year (risk ratio: 0.85; 95% confidence interval: 0.79 to 0.91; p < 0.001), and longest available follow-up (mean 3.28 ± 1.04 years; risk ratio: 0.86; 95% confidence interval: 0.81 to 0.92; p < 0.001), potentially caused by less moderate/severe aortic insufficiency (p = 0.001), and lower cardiovascular mortality (p = 0.009). The female survival advantage remained consistent across multiple secondary analyses. The risk of stroke, moderate/severe aortic insufficiency, and all-cause mortality seemed to vary based on the type of valve used; however, without significant subgroup interactions. CONCLUSIONS: Despite a higher upfront risk of complications, women derive a better long-term survival after TAVR compared with men.

RESUMO

Abstract Background: Depressive symptoms are independently associated with an increased risk of cardiovascular disease (CVD) among individuals with non-diagnosed CVD. The mechanisms underlying this association, however, remain unclear. Inflammation has been indicated as a possible mechanistic link between depression and CVD. Objectives: This study evaluated the association between persistent depressive symptoms and the onset of low-grade inflammation. Methods: From a database of 1,508 young (mean age: 41 years) individuals with no CVD diagnosis who underwent at least two routine health evaluations, 134 had persistent depressive symptoms (Beck Depression Inventory - BDI ≥ 10, BDI+) and 1,374 had negative symptoms at both time points (BDI-). All participants had been submitted to repeated clinical and laboratory evaluations at a regular follow-up with an average of 26 months from baseline. Low-grade inflammation was defined as plasma high-sensitivity C-Reactive Protein (CRP) concentrations > 3 mg/L. The outcome was the incidence of low-grade inflammation evaluated by the time of the second clinical evaluation. Results: The incidence of low-grade inflammation was more frequently observed in the BDI+ group compared to the BDI- group (20.9% vs. 11.4%; p = 0.001). After adjusting for sex, age, waist circumference, body mass index, levels of physical activity, smoking, and prevalence of metabolic syndrome, persistent depressive symptoms remained an independent predictor of low-grade inflammation onset (OR = 1.76; 95% CI: 1.03-3.02; p = 0.04). Conclusions: Persistent depressive symptoms were independently associated with low-grade inflammation onset among healthy individuals.


Resumo Fundamento: Sintomas depressivos estão associados de forma independente ao risco aumentado de doença cardiovascular (DCV) em indivíduos com DCV não diagnosticada. Os mecanismos subjacentes a essa associação, entretanto, não estão claros. Inflamação tem sido indicada como um possível elo mecanicista entre depressão e DCV. Objetivos: Este estudo avaliou a associação entre sintomas depressivos persistentes e o início de inflamação de baixo grau. Métodos: De um banco de dados de 1.508 indivíduos jovens (idade média: 41 anos) sem diagnóstico de DCV submetidos a pelo menos duas avaliações de saúde de rotina, 134 tinham sintomas depressivos persistentes (Inventário de Depressão de Beck - BDI ≥10, BDI+) e 1.374 não apresentavam sintomas em nenhuma das ocasiões (BDI-). Todos os participantes foram submetidos a repetidas avaliações clínicas e laboratoriais em seguimento regular, cuja média foi de 26 meses desde a condição basal. Definiu-se inflamação de baixo grau como concentração plasmática de proteína C reativa (PCR) ultrassensível > 3 mg/L. O desfecho foi a incidência de inflamação de baixo grau por ocasião da segunda avaliação clínica. Resultados: A incidência de inflamação de baixo grau foi maior no grupo BDI+ em comparação ao grupo BDI- (20,9% vs. 11,4%; p = 0,001). Após ajuste para sexo, idade, circunferência abdominal, índice de massa corporal, níveis de atividade física, tabagismo e prevalência de síndrome metabólica, os sintomas depressivos persistentes continuaram sendo um preditor independente de início de inflamação de baixo grau (OR = 1,76; IC 95%: 1,03-3,02; p = 0,04). Conclusões: Sintomas depressivos persistentes foram independentemente associados com início de inflamação de baixo grau em indivíduos saudáveis.

RESUMO

Rivaroxaban is an oral direct factor Xa inhibitor, therapeutically indicated in the treatment of thromboembolic diseases. As other new oral anticoagulants, routine monitoring of rivaroxaban is not necessary, but important in some clinical circumstances. In our study a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was validated to measure rivaroxaban plasmatic concentration. Our method used a simple sample preparation, protein precipitation, and a fast chromatographic run. It was developed a precise and accurate method, with a linear range from 2 to 500 ng/mL, and a lower limit of quantification of 4 pg on column. The new method was compared to a reference method (anti-factor Xa activity) and both presented a good correlation (r = 0.98, p < 0.001). In addition, we validated hemolytic, icteric or lipemic plasma samples for rivaroxaban measurement by HPLC-MS/MS without interferences. The chromogenic and HPLC-MS/MS methods were highly correlated and should be used as clinical tools for drug monitoring. The method was applied successfully in a group of 49 real-life patients, which allowed an accurate determination of rivaroxaban in peak and trough levels.

RESUMO

OBJECTIVES: This study aimed to compare gender-related differences in outcomes of patients undergoing TAVI over a long-term follow-up period. BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been considered the standard therapy for patients with inoperable or high-risk symptomatic aortic stenosis. The influence of gender-related differences in outcomes of patients undergoing TAVI is currently on debate. METHODS: From January 2008 to January 2015, 819 patients (49% men) underwent TAVI and were included in a multicenter Brazilian registry. Patients were followed-up and clinical outcomes were evaluated according to the updated Valve Academic Research Consortium-2 criteria. RESULTS: Mean follow-up was 497 ± 478 days. Compared with women, men had a lower rate of major or life-threatening bleeding (12.0% vs. 20.6%; HR = 0.57 [95CI% 0.40-0.81]; P = 0.001), and major vascular complications (6% vs. 11.7%; HR = 0.50 [95CI% 0.31-0.82]; P = 0.004). At 30 days, all-cause mortality was lower in men than in women (6.5% vs. 11.5%; P = 0.013), however, cumulative all-cause mortality was similar between groups (25.9% vs. 29.7%, men and women, respectively, HR = 0.92 [95CI% 0.71-1.19]; P = 0.52) over the entire follow-up period. By adjusted Cox regression model, renal function, diabetes, peripheral artery disease, and chronic obstructive pulmonary disease (COPD) remained independently predictors of all-cause mortality. CONCLUSIONS: In this large-scale study evaluating patients undergoing TAVI, 30-day mortality was higher among women than men driven by significant higher rates of major or life-threatening bleeding and major vascular complications. However, all-cause mortality on long-term follow-up was similar between groups. © 2016 Wiley Periodicals, Inc.
