RESUMO

Myocardial injury after noncardiac surgery (MINS) includes patients with traditional myocardial infarction and those with ischemic myocardial injury after surgery. This study evaluated the prognostic value of MINS on major cardiovascular events and 30-day mortality, and determined independent preoperative predictors of MINS in patients after noncardiac surgery. This multicenter prospective cohort study was part of the VISION Study. The sample consisted of 2504 patients who underwent noncardiac surgery at 2 tertiary hospitals in Brazil between September 2008 and July 2012. Troponin Ts were measured 6-12 hours, and on days 1-3 after surgery. Cox regression analyses were performed to identify independent variables of major outcomes. A total of 314 (13%) patients were diagnosed with MINS, of which 26 (8%) died. Length-of-hospital stay of MINS patients was 3 times higher (18 ± 22 days vs 5.8 ± 11 days). In multivariate analysis, 30-day mortality was significantly higher among patients with MINS (hazard ratio [HR] 3.17 (95% confidence interval [CI] 1.56-6.41)), and major bleeding (HR 5.76 (95% CI 2.75-12.05)), sepsis (HR 5.08 (95% CI 2.25-11.46)), active cancer (HR 4.22 (95% CI 1.98-8.98)), and general surgery (HR 3.11 (95% CI 1.51-6.41)). Multivariable analysis indicated a higher chance of MINS in patients ≥75 years of age, history of diabetes mellitus, hypertension, heart failure, coronary disease, and end-stage renal failure. The incidence of MINS within 30 days after noncardiac surgery is related to higher mortality. Postoperative troponin monitoring in elder patients and with risk factors for atherosclerotic disease may help reduce postoperative cardiovascular events.

RESUMO

BACKGROUND: Despite the association between cardiovascular diseases and periodontitis, there are scarce data on the impact of oral health in the dietary intake of patients with coronary artery disease (CAD). The aim of this study was to assess the association between dietary intake with periodontitis and present teeth in individuals with stable CAD. METHODS: This cross-sectional study included 115 patients with stable CAD (76 males, aged 61.0 ± 8.3 years) who were under cardiovascular care in an outpatient clinic for at least 3 months. Dietary intake was recorded applying a food frequency questionnaire previously validated. Periodontal examinations were performed by two calibrated examiners in six sites per tooth from all present teeth. Blood samples were collected to determine serum levels of lipids. Multivariable logistic and linear regression models were fitted to evaluate the association between dietary outcomes and oral health variables. RESULTS: Individuals with periodontitis had significantly higher percentage of total energy intake from fried foods, sweets, and beans, and also had lower consumption of fruits than those without periodontitis. Presence of periodontitis was associated with lower percentage of individuals who reached the nutritional recommendation of monounsaturated fatty acids and higher blood concentration of triglycerides. Having a greater number of present teeth (≥20 teeth) was associated with higher intake of fibers and total calories. CONCLUSION: In patients with stable CAD, the presence of periodontitis and tooth loss were associated with a poor dietary intake of nutrients and healthy foods, which are important for cardiovascular prevention.

RESUMO

AIM: To assess the effect of periodontal therapy (PT) on cardiovascular blood biomarkers. MATERIALS AND METHODS: This single-blind, parallel-design, randomized controlled trial included patients with stable coronary artery disease and periodontitis. The test group (TG) received non-surgical PT, whereas the control group (CG) received one session of plaque removal. Plasma levels of C-reactive protein (CRP), glycated haemoglobin, lipids and cytokines (IL-1ß, IL-6, IL-8, IL-10, IFN-γ and TNF-α) were measured at baseline and after 3 months. RESULTS: Eighty-two patients (74.4% women, mean age 59.6 years) were analysed. TG had significantly better periodontal parameters than CG after 3 months, but no significant differences in blood markers were observed between them. In a post hoc subgroup analysis in patients with baseline CRP <3 mg/L, a significant increase in CRP was observed in CG (1.44 ± 0.82 mg/L to 4.35 ± 7.85 mg/L, p = 0.01), whereas CRP remained unchanged in TG (1.40 ± 0.96 mg/L to 1.33 ± 1.26 mg/L, p = 0.85), resulting in a significant difference between groups at 3 months. In patients with CRP ≥3 mg/L, a significant reduction in CRP was observed only in TG (11.3 ± 12.8 mg/L to 5.7 ± 4.1 mg/L, p = 0.04). Levels of IL-6 and IL-8 were significantly lower in TG than CG at 3 months. CONCLUSIONS: PT leads to lower levels of CRP, IL-6 and IL-8 in cardiovascular patients with high CRP levels.

RESUMO

PURPOSE OF REVIEW: This paper reviews performance measure in health, their importance, and methodologic issues, focusing on metrics for health failure patients. Quality measures are instruments to assess structural aspects or processes of care aiming to guarantee that optimal patient outcomes are achieved. As heart failure is a chronic condition in which established therapies reduce mortality and hospital admissions, there are quite a lot of initiatives that aim to monitor for quality of care and to coordinate the disease management. RECENT FINDINGS: Several performance measures were validated for these patients, from process of care (left ventricular function assessment and use of ACEi/ARBs and beta-blockers) to health outcomes (hospital mortality and readmissions). In the early years, studies demonstrated a relationship between quality measurements and health outcomes. Nonetheless, more recent ones based on large databases of patients' medical records have shown that traditional indicators explain only a small fraction of health and patient reported- and perceived outcomes. Public reporting of quality measures and payment conditioned to the quality of care provided were not able to show benefit in terms of hard outcomes. Data science and big data methods are promising in providing actionable knowledge for quality improvement, with real-time data that could support decision-making. Heart failure is a chronic condition that has proven to be useful for measuring medical and healthcare quality. Evidence-based indicators have already reached high rates of adherence and are currently poorly correlated with outcomes. Using real-life data and based on the patient's perspective can be useful tools to improve these indicators.

RESUMO

OBJECTIVE: To assess the effects of periodontal treatment on endothelial function in patients with coronary artery disease. MATERIALS AND METHODS: A randomized controlled trial was conducted with 69 patients with stable coronary disease and severe periodontitis. The test group received nonsurgical periodontal therapy consisting of personalized oral hygiene instructions, subgingival scaling, and root planing per quadrant, whereas the control group received equal treatment after the study period. Endothelial function was assessed by measurement of brachial artery flow-mediated dilation, concentrations of sVCAM-1, sICAM-1, and P-selectin in serum before and 3 months after periodontal therapy. RESULTS: The test group exhibited statistically better periodontal parameters-plaque, probing depth, periodontal attachment loss, and bleeding on probing. No significant improvements were observed in the control (1.37%) and test (1.39%) groups in flow-mediated dilation, with no significant between-group difference. sVCAM-1 concentration increased in the control group (997.6 ± 384.4-1201.8 ± 412.5; p = 0.03), whereas in the test group, no significant changes were observed (915.1 ± 303.8-1050.3 ± 492.3; p = 0.17), resulting in a significant difference between the two groups (p = 0.04). The same pattern was observed for concentrations of sICAM-1. CONCLUSION: Periodontal treatment did not provide better vasodilation in patients with coronary disease in a short-term follow-up period, although it maintained blood concentrations of markers of vascular inflammation.

RESUMO

Background: Several (neo)adjuvant treatments for patients with HER2-positive breast cancer have been compared in different randomized clinical trials. Since it is not feasible to conduct adequate pairwise comparative trials of all these therapeutic options, network meta-analysis offers an opportunity for more detailed inference for evidence-based therapy. Methods: Phase II/III randomized clinical trials comparing two or more different (neo)adjuvant treatments for HER2-positive breast cancer patients were included. Relative treatment effects were pooled in two separate network meta-analyses for overall survival (OS) and disease-free survival (DFS). Results: 17 clinical trials met our eligibility criteria. Two different networks of trials were created based on the availability of the outcomes: OS network (15 trials: 37,837 patients); and DFS network (17 trials: 40,992 patients). Two studies-the ExteNET and the NeoSphere trials-were included only in this DFS network because OS data have not yet been reported. The concept of the dual anti-HER2 blockade proved to be the best option in terms of OS and DFS. Chemotherapy (CT) plus trastuzumab (T) and lapatinib (L) and CT + T + Pertuzumab (P) are probably the best treatment options in terms of OS, with 62.47% and 22.06%, respectively. In the DFS network, CT + T + Neratinib (N) was the best treatment option with 50.55%, followed by CT + T + P (26.59%) and CT + T + L (20.62%). Conclusion: This network meta-analysis suggests that dual anti-HER2 blockade with trastuzumab plus either lapatinib or pertuzumab are probably the best treatment options in the (neo)adjuvant setting for HER2-positive breast cancer patients in terms of OS gain. Mature OS results are still expected for the Aphinity trial and for the sequential use of trastuzumab followed by neratinib, the treatment that showed the best performance in terms of DFS in our analysis.

RESUMO

BACKGROUND: Myocardial injury after noncardiac surgery (MINS) is a mostly asymptomatic condition that is strongly associated with 30-day mortality; however, it remains mostly undetected without systematic troponin T monitoring. We evaluated the cost and consequences of postoperative troponin T monitoring to detect MINS. METHODS: We conducted a model-based cost-consequence analysis to compare the impact of routine troponin T monitoring versus standard care (troponin T measurement triggered by ischemic symptoms) on the incidence of MINS detection. Model inputs were based on Canadian patients enrolled in the Vascular Events in Noncardiac Surgery Patients Cohort Evaluation (VISION) study, which enrolled patients aged 45 years or older undergoing inpatient noncardiac surgery. We conducted probability analyses with 10 000 iterations and extensive sensitivity analyses. RESULTS: The data were based on 6021 patients (48% men, mean age 65 [standard deviation 12] yr). The 30-day mortality rate for MINS was 9.6%. We determined the incremental cost to avoid missing a MINS event as $1632 (2015 Canadian dollars). The cost-effectiveness of troponin monitoring was higher in patient subgroups at higher risk for MINS, e.g., those aged 65 years or more, or with a history of atherosclerosis or diabetes ($1309). CONCLUSION: The costs associated with a troponin T monitoring program to detect MINS were moderate. Based on the estimated incremental cost per health gain, implementation of postoperative troponin T monitoring seems appealing, particularly in patients at high risk for MINS.

RESUMO

OBJECTIVE: Estimate the cost-effectiveness of a nurse-led home visit (HV) intervention as compared with the standard HF management, within a randomized clinical trial in Brazil. STUDY DESIGN: Cost-effectiveness study within a randomized trial. METHODS: To assess the cost-effectiveness of four home visits and four telephone calls by nurses in the management of patients with HF within a randomized clinical trial (RCT: NCT01213875) in a perspective Public (PHS-Public Healthcare System) and private healthcare systems of Brazil during time frame of 24 weeks. The outcome was a composite endpoint hospital readmission rate (first visit to the emergency room (ER) and hospital readmission), or all-cause death and incremental cost-effectiveness ratio (ICER) of the study intervention to conventional management. RESULTS: Home-based intervention was associated with a reduction in composite endpoint (RR 0.73; 95% confidence interval 0.54 - 0.99; P = 0.049), but at greater cost from the PHS perspective. The ICER at 24 weeks was R$585 per hospital readmission visit prevented. Within the private health insurance framework, home visits were associated with lower costs and lower readmission rates. Results were sensitive to the relative risk of the study intervention, admissions and intervention costs. CONCLUSIONS: In Brazil, an intervention based on nurse-led home visits of patients with HF showed a favorable cost-effectiveness profile within the framework of the PHS and was dominant within the private healthcare system. Our analysis suggests that implementation of this program could not only benefit patients, but also provide a financial incentive to health administrators.

RESUMO

Objective: To assess the effectiveness of three mood disorder treatment algorithms in a sample of patients seeking care in the Brazilian public healthcare system. Methods: A randomized pragmatic trial was conducted with an algorithm developed for treating episodes of major depressive disorder (MDD), bipolar depressive episodes and mixed episodes of bipolar disorder (BD). Results: The sample consisted of 259 subjects diagnosed with BD or MDD (DSM-IV-TR). After the onset of symptoms, the first treatment occurred ∼6 years and the use of mood stabilizers began ∼12 years. All proposed algorithms were effective, with response rates around 80%. The majority of the subjects took 20 weeks to obtain a therapeutic response. Conclusions: The algorithms were effective with the medications available through the Brazilian Unified Health System. Because therapeutic response was achieved in most subjects by 20 weeks, a follow-up period longer than 12 weeks may be required to confirm adequate response to treatment. Remission of symptoms is still the main desired outcome. Subjects who achieved remission recovered more rapidly and remained more stable over time.

RESUMO

Contrast-induced acute kidney injury (CI-AKI) is a common event after percutaneous coronary intervention (PCI). Presently, the main strategy to avoid CI-AKI lies in saline hydration, since to date none pharmacologic prophylaxis proved beneficial. Our aim was to determine if a low complexity mortality risk model is able to predict CI-AKI in patients undergoing PCI after ST elevation myocardial infarction (STEMI). We have included patients with STEMI submitted to primary PCI in a tertiary hospital. The definition of CI-AKI was a raise of 0.3 mg/dL or 50% in post procedure (24-72 h) serum creatinine compared to baseline. Age, glomerular filtration and ejection fraction were used to calculate ACEF-MDRD score. We have included 347 patients with mean age of 60 years. In univariate analysis, age, diabetes, previous ASA use, Killip 3 or 4 at admission, ACEF-MDRD and Mehran scores were predictors of CI-AKI. After multivariate adjustment, only ACEF-MDRD score and diabetes remained CI-AKI predictors. Areas under the ROC curve of ACEF-MDRD and Mehran scores were 0.733 (0.68-0.78) and 0.649 (0.59-0.70), respectively. When we compared both scores with DeLong test ACEF-MDRDs AUC was greater than Mehran's (P = 0.03). An ACEF-MDRD score of 2.33 or lower has a negative predictive value of 92.6% for development of CI-AKI. ACEF-MDRD score is a user-friendly tool that has an excellent CI-AKI predictive accuracy in patients undergoing primary percutaneous coronary intervention. Moreover, a low ACEF-MDRD score has a very good negative predictive value for CI-AKI, which makes this complication unlikely in patients with an ACEF-MDRD score of <2.33.

RESUMO

OBJECTIVE: To determine the prognostic relevance, clinical characteristics, and 30-day outcomes associated with myocardial injury after noncardiac surgery (MINS) in vascular surgical patients. BACKGROUND: MINS has been independently associated with 30-day mortality after noncardiac surgery. The characteristics and prognostic importance of MINS in vascular surgery patients are poorly described. METHODS: This was an international prospective cohort study of 15,102 noncardiac surgery patients 45 years or older, of whom 502 patients underwent vascular surgery. All patients had fourth-generation plasma troponin T (TnT) concentrations measured during the first 3 postoperative days. MINS was defined as a TnT of 0.03 ng/mL of higher secondary to ischemia. The objectives of the present study were to determine (i) if MINS is prognostically important in vascular surgical patients, (ii) the clinical characteristics of vascular surgery patients with and without MINS, (iii) the 30-day outcomes for vascular surgery patients with and without MINS, and (iv) the proportion of MINS that probably would have gone undetected without routine troponin monitoring. RESULTS: The incidence of MINS in the vascular surgery patients was 19.1% (95% confidence interval (CI), 15.7%-22.6%). 30-day all-cause mortality in the vascular cohort was 12.5% (95% CI 7.3%-20.6%) in patients with MINS compared with 1.5% (95% CI 0.7%-3.2%) in patients without MINS (P < 0.001). MINS was independently associated with 30-day mortality in vascular patients (odds ratio, 9.48; 95% CI, 3.46-25.96). The 30-day mortality was similar in MINS patients with (15.0%; 95% CI, 7.1-29.1) and without an ischemic feature (12.2%; 95% CI, 5.3-25.5, P = 0.76). The proportion of vascular surgery patients who suffered MINS without overt evidence of myocardial ischemia was 74.1% (95% CI, 63.6-82.4). CONCLUSIONS: Approximately 1 in 5 patients experienced MINS after vascular surgery. MINS was independently associated with 30-day mortality. The majority of patients with MINS were asymptomatic and would have gone undetected without routine postoperative troponin measurement.

RESUMO

BACKGROUND: Although heart failure (HF) has high morbidity and mortality, studies in Latin America on causes and predictors of in-hospital mortality are scarce. We also do not know the evolution of patients with compensated HF hospitalized for other reasons. OBJECTIVE: To identify causes and predictors of in-hospital mortality in patients hospitalized for acute decompensated HF (ADHF), compared to those with HF and admitted to the hospital for non-HF related causes (NDHF). METHODS: Historical cohort of patients hospitalized in a public tertiary hospital in Brazil with a diagnosis of HF identified by the Charlson Comorbidity Index (CCI). RESULTS: A total of 2056 patients hospitalized between January 2009 and December 2010 (51% men, median age of 71 years, length of stay of 15 days) were evaluated. There were 17.6% of deaths during hospitalization, of which 58.4% were non-cardiovascular (63.6% NDHF vs 47.4% ADHF, p = 0.004). Infectious causes were responsible for most of the deaths and only 21.6% of the deaths were attributed to HF. The independent predictors of in-hospital mortality were similar between the groups and included: age, length of stay, elevated potassium, clinical comorbidities, and CCI. Renal insufficiency was the most relevant predictor in both groups. CONCLUSION: Patients hospitalized with HF have high in-hospital mortality, regardless of the primary reason for hospitalization. Few deaths are directly attributed to HF; Age, renal function and levels of serum potassium, length of stay, comorbid burden and CCI were independent predictors of in-hospital death in a Brazilian tertiary hospital.

Resumo Fundamento: Apesar da insuficiência cardíaca (IC) apresentar elevada morbimortalidade, são escassos os estudos na América Latina sobre causas e preditores de mortalidade intra-hospitalar. Desconhece-se, também, a evolução de pacientes com IC compensada hospitalizados por outros motivos. Objetivo: Identificar causas e preditores de mortalidade intra-hospitalar em pacientes que internam por IC aguda descompensada (ICAD), comparativamente aqueles que possuem IC e internam por outras condições (ICND). Métodos: Coorte histórica de pacientes internados em um hospital público terciário no Brasil com diagnóstico de IC identificados pelo escore de comorbidade de Charlson (ECCharlson). Resultados: Foram avaliados 2056 pacientes que internaram entre janeiro de 2009 e dezembro de 2010 (51% homens; idade mediana de 71 anos; tempo de permanência de 15 dias). Ocorreram 17,6% de óbitos durante a internação, dos quais 58,4% por causa não cardiovascular (63,6% ICND versus 47,4% ICAD, p = 0,004). As causas infecciosas foram responsáveis pela maior parte dos óbitos e apenas 21.6% das mortes foram atribuídas à IC. Os preditores independentes de mortalidade intra-hospitalar foram semelhantes entre os grupos e incluíram: idade, tempo de permanência, potássio elevado, comorbidades clínicas e ECCharlson. A insuficiência renal foi o preditor de maior relevância em ambos grupos. Conclusão: Pacientes internados com IC apresentam elevada mortalidade intra-hospitalar, independentemente do motivo primário de internação. Poucos óbitos são diretamente atribuídos à IC; Idade, alteração na função renal e níveis séricos de potássio, tempo de permanência, comorbidades e ECCharlson foram preditores independentes de morte intra-hospitalar em hospital terciário brasileiro.

RESUMO

OBJECTIVES: The aim of this research is to evaluate the relative cost-effectiveness of functional and anatomical strategies for diagnosing stable coronary artery disease (CAD), using exercise (Ex)-ECG, stress echocardiogram (ECHO), single-photon emission CT (SPECT), coronary CT angiography (CTA) or stress cardiacmagnetic resonance (C-MRI). SETTING: Decision-analytical model, comparing strategies of sequential tests for evaluating patients with possible stable angina in low, intermediate and high pretest probability of CAD, from the perspective of a developing nation's public healthcare system. PARTICIPANTS: Hypothetical cohort of patients with pretest probability of CAD between 20% and 70%. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome is cost per correct diagnosis of CAD. Proportion of false-positive or false-negative tests and number of unnecessary tests performed were also evaluated. RESULTS: Strategies using Ex-ECG as initial test were the least costly alternatives but generated more frequent false-positive initial tests and false-negative final diagnosis. Strategies based on CTA or ECHO as initial test were the most attractive and resulted in similar cost-effectiveness ratios (I$ 286 and I$ 305 per correct diagnosis, respectively). A strategy based on C-MRI was highly effective for diagnosing stable CAD, but its high cost resulted in unfavourable incremental cost-effectiveness (ICER) in moderate-risk and high-risk scenarios. Non-invasive strategies based on SPECT have been dominated. CONCLUSIONS: An anatomical diagnostic strategy based on CTA is a cost-effective option for CAD diagnosis. Functional strategies performed equally well when based on ECHO. C-MRI yielded acceptable ICER only at low pretest probability, and SPECT was not cost-effective in our analysis.

RESUMO

Importance: Little is known about the relationship between perioperative high-sensitivity troponin T (hsTnT) measurements and 30-day mortality and myocardial injury after noncardiac surgery (MINS). Objective: To determine the association between perioperative hsTnT measurements and 30-day mortality and potential diagnostic criteria for MINS (ie, myocardial injury due to ischemia associated with 30-day mortality). Design, Setting, and Participants: Prospective cohort study of patients aged 45 years or older who underwent inpatient noncardiac surgery and had a postoperative hsTnT measurement. Starting in October 2008, participants were recruited at 23 centers in 13 countries; follow-up finished in December 2013. Exposures: Patients had hsTnT measurements 6 to 12 hours after surgery and daily for 3 days; 40.4% had a preoperative hsTnT measurement. Main Outcomes and Measures: A modified Mazumdar approach (an iterative process) was used to determine if there were hsTnT thresholds associated with risk of death and had an adjusted hazard ratio (HR) of 3.0 or higher and a risk of 30-day mortality of 3% or higher. To determine potential diagnostic criteria for MINS, regression analyses ascertained if postoperative hsTnT elevations required an ischemic feature (eg, ischemic symptom or electrocardiography finding) to be associated with 30-day mortality. Results: Among 21 842 participants, the mean age was 63.1 (SD, 10.7) years and 49.1% were female. Death within 30 days after surgery occurred in 266 patients (1.2%; 95% CI, 1.1%-1.4%). Multivariable analysis demonstrated that compared with the reference group (peak hsTnT <5 ng/L), peak postoperative hsTnT levels of 20 to less than 65 ng/L, 65 to less than 1000 ng/L, and 1000 ng/L or higher had 30-day mortality rates of 3.0% (123/4049; 95% CI, 2.6%-3.6%), 9.1% (102/1118; 95% CI, 7.6%-11.0%), and 29.6% (16/54; 95% CI, 19.1%-42.8%), with corresponding adjusted HRs of 23.63 (95% CI, 10.32-54.09), 70.34 (95% CI, 30.60-161.71), and 227.01 (95% CI, 87.35-589.92), respectively. An absolute hsTnT change of 5 ng/L or higher was associated with an increased risk of 30-day mortality (adjusted HR, 4.69; 95% CI, 3.52-6.25). An elevated postoperative hsTnT (ie, 20 to <65 ng/L with an absolute change ≥5 ng/L or hsTnT ≥65 ng/L) without an ischemic feature was associated with 30-day mortality (adjusted HR, 3.20; 95% CI, 2.37-4.32). Among the 3904 patients (17.9%; 95% CI, 17.4%-18.4%) with MINS, 3633 (93.1%; 95% CI, 92.2%-93.8%) did not experience an ischemic symptom. Conclusions and Relevance: Among patients undergoing noncardiac surgery, peak postoperative hsTnT during the first 3 days after surgery was significantly associated with 30-day mortality. Elevated postoperative hsTnT without an ischemic feature was also associated with 30-day mortality.

RESUMO

MATERIAL AND METHODS: This cross-sectional study included 91 patients with stable CAD who had been under optimized cardiovascular care. Blood levels of IL-1ß, IL-6, IL-8, IL-10, IFN-γ, and TNF-α were measured by Luminex technology. A full-mouth periodontal examination was conducted to record probing depth (PD) and clinical attachment (CA) loss. Multiple linear regression models, adjusting for gender, body mass index, oral hypoglycemic drugs, smoking, and occurre:nce of acute myocardial infarction were applied. RESULTS: CAD patients that experienced major events had higher concentrations of IFN-γ (median: 5.05 pg/mL vs. 3.01 pg/mL; p=0.01), IL-10 (median: 2.33 pg/mL vs. 1.01 pg/mL; p=0.03), and TNF-α (median: 9.17 pg/mL vs. 7.47 pg/mL; p=0.02). Higher numbers of teeth with at least 6 mm of CA loss (R2=0.07) and PD (R2=0.06) were significantly associated with higher IFN-γ log concentrations. Mean CA loss (R2=0.05) and PD (R2=0.06) were significantly related to IL-10 concentrations. Elevated concentrations of TNF-α were associated with higher mean CA loss (R2=0.07). CONCLUSION: Periodontal disease is associated with increased systemic inflammation in stable cardiovascular patients. These findings provide additional evidence supporting the idea that periodontal disease can be a prognostic factor in cardiovascular patients.

RESUMO

ABSTRACT Periodontal disease has been associated with elevations of blood cytokines involved in atherosclerosis in systemically healthy individuals, but little is known about this association in stable cardiovascular patients. The aim of this study was to assess the association between periodontal disease (exposure) and blood cytokine levels (outcomes) in a target population of patients with stable coronary artery disease (CAD). Material and Methods This cross-sectional study included 91 patients with stable CAD who had been under optimized cardiovascular care. Blood levels of IL-1β, IL-6, IL-8, IL-10, IFN-γ, and TNF-α were measured by Luminex technology. A full-mouth periodontal examination was conducted to record probing depth (PD) and clinical attachment (CA) loss. Multiple linear regression models, adjusting for gender, body mass index, oral hypoglycemic drugs, smoking, and occurre:nce of acute myocardial infarction were applied. Results CAD patients that experienced major events had higher concentrations of IFN-γ (median: 5.05 pg/mL vs. 3.01 pg/mL; p=0.01), IL-10 (median: 2.33 pg/mL vs. 1.01 pg/mL; p=0.03), and TNF-α (median: 9.17 pg/mL vs. 7.47 pg/mL; p=0.02). Higher numbers of teeth with at least 6 mm of CA loss (R2=0.07) and PD (R2=0.06) were significantly associated with higher IFN-γ log concentrations. Mean CA loss (R2=0.05) and PD (R2=0.06) were significantly related to IL-10 concentrations. Elevated concentrations of TNF-α were associated with higher mean CA loss (R2=0.07). Conclusion Periodontal disease is associated with increased systemic inflammation in stable cardiovascular patients. These findings provide additional evidence supporting the idea that periodontal disease can be a prognostic factor in cardiovascular patients.

RESUMO

Fundamento: A inflamação tem sido reconhecida como um importante fator de risco para as doenças cardiovasculares. A doença periodontal pode acarretar alterações de alguns marcadores plasmáticos envolvidos no processo aterogênico. Objetivo: Avaliar a associação entre a doença periodontal e os níveis lipídicos ao longo do tempo em pacientes com doença arterial coronariana crônica. Métodos: Este estudo de coorte retrospectivo incluiu uma amostra de pacientes cardiopatas crônicos recebendo atendimento em um ambulatório de atenção terciária de cardiopatia isquêmica. Dos 239 pacientes elegíveis, foram incluídos 80 que apresentavam dados retrospectivos de perfil lipídico entre 2009 e 2011. Foram realizados exames periodontais de todos os dentes presentes em 2011. Modelos múltiplos de equações de estimação generalizada foram aplicados para avaliar a associação entre parâmetros periodontais e alterações ao longo do tempo nos seguintes desfechos: triglicerídeos, colesterol total, LDL-colesterol e HDL-colesterol, com ajustes para idade, índice de massa corporal, fumo, uso de hipoglicemiante oral e tempo de acompanhamento. Resultados: Durante um tempo médio de acompanhamento de 713 dias, não houve mudanças significativas nas concentrações de triglicerídeos, colesterol total e LDL-colesterol. Um aumento significativo de 31,6% nos níveis de HDL-colesterol foi observado entre 2009 e 2011. Observamos uma associação negativa e significativa entre a média individual de perda de inserção periodontal e nível de HDL-colesterol, indicando que quanto maior a perda de inserção, mais baixos os níveis de HDL-colesterol ao longo do tempo. Conclusão: A doença periodontal destrutiva pode estar relacionada com um pior controle lipídico, particularmente relacionado a níveis de HDL-colesterol, em pacientes cardiopatas crônicos


Background: Inflammation has been recognized as an important risk factor for cardiovascular diseases. Periodontal disease may alter some plasma markers involved in the atherogenic process. Objective: To assess the association between periodontal disease and lipid levels over time in patients with chronic coronary artery disease.Methods: This retrospective cohort study included a sample of patients with chronic heart disease receiving care in an outpatient tertiary care for ischemic heart disease. Of 239 patients eligible for the study, we included 80 patients who had available retrospective data of lipid profile between 2009 and 2011. We performed periodontal examinations of all teeth present in 2011. Multiple models of generalized estimating equations were applied to assess the association between periodontal parameters and changes over time in the following outcomes: triglycerides, total cholesterol, LDL-cholesterol, and HDL-cholesterol levels adjusted for age, body mass index, smoking, use of oral hypoglycemic, and follow-up duration. Results: During a mean follow-up time of 713 days, there were no significant changes in the concentrations of triglycerides, total cholesterol, and LDL-cholesterol. A significant 31.6% increase in HDL-cholesterol levels was observed between 2009 and 2011. We observed a significant negative association between mean individual periodontal attachment loss and HDL- cholesterol levels, indicating that the greater the attachment loss, the lower the HDL-cholesterol level over time. Conclusion: Destructive periodontal disease may be related to a worse lipid control, specifically regarding HDL-cholesterol levels, in chronic cardiac patients

RESUMO

Several tests exist for diagnosing coronary artery disease, with varying accuracy and cost. We sought to provide cost-effectiveness information to aid physicians and decision-makers in selecting the most appropriate testing strategy. We used the state-transitions (Markov) model from the Brazilian public health system perspective with a lifetime horizon. Diagnostic strategies were based on exercise electrocardiography (Ex-ECG), stress echocardiography (ECHO), single-photon emission computed tomography (SPECT), computed tomography coronary angiography (CTA), or stress cardiac magnetic resonance imaging (C-MRI) as the initial test. Systematic review provided input data for test accuracy and long-term prognosis. Cost data were derived from the Brazilian public health system. Diagnostic test strategy had a small but measurable impact in quality-adjusted life-years gained. Switching from Ex-ECG to CTA-based strategies improved outcomes at an incremental cost-effectiveness ratio of 3100 international dollars per quality-adjusted life-year. ECHO-based strategies resulted in cost and effectiveness almost identical to CTA, and SPECT-based strategies were dominated because of their much higher cost. Strategies based on stress C-MRI were most effective, but the incremental cost-effectiveness ratio vs CTA was higher than the proposed willingness-to-pay threshold. Invasive strategies were dominant in the high pretest probability setting. Sensitivity analysis showed that results were sensitive to costs of CTA, ECHO, and C-MRI. Coronary CT is cost-effective for the diagnosis of coronary artery disease and should be included in the Brazilian public health system. Stress ECHO has a similar performance and is an acceptable alternative for most patients, but invasive strategies should be reserved for patients at high risk.
