Phytosterol consumption and markers of subclinical atherosclerosis: Cross-sectional results from ELSA-Brasil.

BACKGROUND AND AIMS: Phytosterol (PS) consumption is associated with lower total and LDL-cholesterol (LDL-c) concentrations, but its impact on cardiovascular risk is unclear. This study assessed the effect of usual intake of PS on markers of subclinical atherosclerosis in the Longitudinal Study of Adult Health (ELSA-Brasil). METHODS AND RESULTS: This cross-sectional study included 2560 participants of ELSA-Brasil, aged 48 (43-54) years, with available food frequency questionnaires (FFQ), coronary artery calcium (CAC) scores, carotid intima media thickness (cIMT), and carotid-femoral pulse wave velocity (cf-PWV), at baseline. Several logistic and linear regression models were used, and significance level was set at a P < 0.05. Mean values (SD) for PS consumption were 256 (198) mg/day, CAC 22.78 (110.54) Agatston Units, cf-PWV 9.07 (1.60) m/s and cIMT 0.57 (0.12) mm. PS consumption in Q4 was associated with lower total- and LDL-c levels, and with higher percentiles of cf-PWV (P < 0.001). Proportion of subjects in Q4 of PS consumption was 1.5 times higher among individuals in cf-PWV Q4, than in Q1 (P = 0.002, for comparisons among quartiles). There was a trend (P = 0.003) for higher cf-PWV with higher PS intake. In crude logistic and linear regressions, PS intake was associated with cf-PWV. In the adjusted models, these associations disappeared. No associations were found between PS and cIMT or CAC. CONCLUSIONS: In this large and apparently healthy cross-sectional sample from ELSA-Brasil, usual PS consumption was associated with lower total- and LDL-cholesterol, but not with markers of subclinical atherosclerosis.

Beneficial effects of green banana biomass consumption in patients with pre-diabetes and type 2 diabetes: a randomised controlled trial.

Diabetes mellitus is a global epidemic, characterised as a heterogeneous group of metabolic disorders associated with high risk of CVD. Green banana biomass, which is composed of resistant starches (RS) and cannot be hydrolysed by amylases, delays gastric emptying and modulates insulin sensitivity, thus contributing to improve metabolic disorders. The aim of the present study was to investigate the effects of consumption of RS from green banana biomass on body composition, fasting plasma glucose, glycated Hb (HbA1c) and homeostasis model assessment of insulin resistance in subjects with pre-diabetes or type 2 diabetes on top of treatment. Middle-aged subjects (n 113) of both sexes with pre-diabetes (HbA1c: 5·7-6·4 %) or diabetes (HbA1c ≥ 6·5 %) were randomised to receive nutritional support plus green banana biomass (40 g) (RS: approximately 4·5 g, G1, n 62) or diet alone (G2, n 51) for 24 weeks. Body composition, biochemical analyses and dietary intake were evaluated at the beginning and end of the study. In the experimental group (G1), consumption of RS was associated with reduction in HbA1c (P = 0·0001), fasting glucose (P = 0·021), diastolic blood pressure (P = 0·010), body weight (P = 0·002), BMI (P = 0·006), waist and hip circumferences (P < 0·01), fat mass percentage (P = 0·001) and increase in lean mass percentage (P = 0·011). In controls (G2), reductions were observed in waist and hip circumferences (P < 0·01), HbA1c (P = 0·002) and high-density lipoprotein-cholesterol (P = 0·020). In pre-diabetes or diabetes, non-significant differences were observed in the percentage reduction in HbA1c and fasting glucose in exploratory analyses. Our results indicate that the consumption of bioactive starches is a good dietary strategy to improve metabolic control and body composition.

Monocyte subtypes and the CCR2 chemokine receptor in cardiovascular disease.

Monocytes circulate in the blood and migrate to inflammatory tissues, but their functions can be either detrimental or beneficial, depending on their phenotypes. In humans, classical monocytes are inflammatory cluster of differentiation (CD)14++CD16-CCR2++ cells originated from the bone marrow or spleen reservoirs and comprise ≥92% of monocytes. Intermediate monocytes (CD14++CD16+CCR2+) are involved in the production of anti-inflammatory cytokines [such as interleukin (IL)-10], reactive oxygen species (ROS), and proinflammatory mediators [such as tumor necrosis factor-α (TNF-α) and IL-1ß). Nonclassical monocytes (CD14+CD16++CCR2-) are patrolling cells involved in tissue repair and debris removal from the vasculature. Many studies in both humans and animals have shown the importance of monocyte chemoattractant protein-1 (MCP-1) and its receptor [chemokine receptor of MCP-1 (CCR2)] in pathologies, such as atherosclerosis and myocardial infarction (MI). This review presents the importance of these monocyte subsets in cardiovascular diseases (CVDs), and sheds light on new strategies for the blocking of the MCP-1/CCR2 axis as a therapeutic goal for treating vascular disorders.

Pharmacoinvasive Strategy in Elderly Up to 75 Years or Non-Elderly: Analysis of Biochemical and Cardiac Magnetic Resonance Imaging Parameters. / Estratégia Farmacoinvasiva em Idosos até 75 Anos ou Não Idosos: Análise de Parâmetros Bioquímicos e de Ressonância Nuclear Magnética Cardíaca.

BACKGROUND: Pharmacoinvasive strategy is an alternative when primary percutaneous coronary intervention (PCI) is not feasible. OBJECTIVES: This study aimed to evaluate the effects of early pharmacoinvasive strategy on the infarct size and left ventricular ejection fraction in elderly and non-elderly patients. The role of inflammatory markers was also examined. METHODS: Patients (n=223) with ST segment elevation myocardial infarction (STEMI) were prospectively included and submitted to pharmacological thrombolysis in the first six hours, and underwent coronary angiogram and PCI when necessary, in the first 24 hours. Blood samples were collected in the first day (D1) and after 30 days (D30). Cardiac magnetic resonance imaging (cMRI) was performed at D30. Significance was set at p<0.05. RESULTS: Elderly and non-elderly patients showed similar percentage of infarcted mass (13.7 [6.9-17.0] vs. 14.0 [7.3-26.0], respectively, p=0.13) (median [interquartile range]). However, elderly patients had better left ventricular ejection fraction (53 [45-62] vs. 49 [39-58], p=0.025). Titers of interleukin (IL)1beta, IL-4, IL-6, and IL-10 did not differ between D1 and D30, but elderly patients had higher titers for IL-18 at D1 and D30. Absolute numbers of B and T lymphocytes were similar in both groups at D1 and D30, but elderly patients had higher neutrophil/lymphocyte ratio at D30. Multivariate linear regression analysis of cMRI outcomes in the whole population showed that the independent predictors were not different between elderly and non-elderly patients. CONCLUSION: Pharmacoinvasive strategy in elderly patients was associated with small differences in inflammatory parameters, similar infarct size and better left ventricular function than non-elderly patients.

FUNDAMENTO: A estratégia farmacoinvasiva é uma alternativa na inviabilidade da intervenção coronária percutânea primária (ICP). OBJETIVOS: Este estudo teve como objetivo avaliar os efeitos da estratégia farmacoinvasiva precoce sobre o tamanho da área infartada e a fração de ejeção ventricular esquerda em pacientes idosos e não idosos. O papel dos marcadores inflamatórios também foi avaliado. MÉTODOS: Pacientes (n=223) com infarto do miocárdio com elevação do segmento ST (IAMCSST) foram prospectivamente incluídos e submetidos à trombólise medicamentosa nas primeiras seis horas, e à angiografia coronariana e à ICP, quando necessária, nas primeiras 24 horas. As amostras de sangue foram coletadas no primeiro dia (D1) e 30 dias após (D30). A ressonância magnética cardíaca foi realizada no D30. O nível de significância estatística foi estabelecido em p<0,05. RESULTADOS: Pacientes idosos e não idosos apresentaram porcentagem similares de massa infartada [13,7 (6,9-17,0) vs. 14,0 (7,3-26,0), respectivamente p=0,13)] [mediana (intervalo interquartil)]. No entanto, os pacientes idosos apresentaram maior fração de ejeção ventricular esquerda [53 (45-62) vs. 49 (39-58), p=0,025)]. As concentrações de interleucina (IL)1beta, IL-4, IL-6, e IL-10 não foram diferentes entre D1 e D30, mas pacientes idosos apresentaram níveis mais elevados de IL-18 em D1 e D30. O número absoluto de linfócitos B e T foram similares em ambos os grupos em D1 e D30, porém, pacientes idosos apresentaram uma razão neutrófilo-linfócito mais alta em D30. A análise de regressão linear multivariada dos desfechos de RMC de toda a população do estudo mostrou que os preditores independentes não foram diferentes entre pacientes idosos e não idosos. CONCLUSÃO: A estratégia farmacoinvasiva em pacientes idosos foi associada a pequenas diferenças nos parâmetros inflamatórios, tamanho do infarto similar, e melhor função ventricular esquerda em comparação a pacientes não idosos.

Association between Morning Surge and Left Ventricular Hypertrophy in Obese Hypertensive Patients. / Relação da Ascensão Matinal da Pressão Arterial com a Hipertrofia Ventricular Esquerda em Hipertensos Obesos.

BACKGROUND: Weight gain can trigger mechanisms that increase blood pressure. Nevertheless, obesity causes structural changes in the myocardium, including increased ventricular mass, atrial dilatation, and diastolic and systolic dysfunction. Additionally, blood pressure variations, like morning surge (MS) in obese hypertensive patients may have clinical relevance in cardiovascular events. Although morning blood pressure surge is a physiological phenomenon, excess MS can be considered an independent risk factor for cardiovascular events. OBJECTIVE: To evaluate MS values and their association with left ventricular hypertrophy (LVH) and nocturnal dipping (ND) in obese and non-obese hypertensive patients. METHODS: A cross-sectional study that evaluated BP measurements by ambulatory blood pressure monitoring (ABPM) and the presence of LVH by echocardiography in 203 hypertensive outpatients, divided into two groups: 109 non-obese and 94 obese hypertensives patients. The significance level was set at 0.05 in two-tailed tests. RESULTS: A MS above 20 mmHg by ABPM was detected in 59.2% of patients in the non-obese group and 40.6% in the obese group. LVH was found in 18.1% and 39.3% of patients in the non-obese and obese groups, respectively, p<0.001. In the "obese group", it was observed that a MS>16 mmHg was associated with LVH, [prevalence ratio: 2.80; 95%CI (1.12-6.98), p=0.03]. For the non-obese group, the cut-off point of MS for this association was >22 mmHg. CONCLUSION: High MS was positively associated with LVH, with a particular behavior in the hypertensive obese group.

A randomized trial of rosuvastatin in the prevention of venous thromboembolism.

BACKGROUND: Controversy persists regarding the extent of shared pathways between arterial and venous thrombosis and whether treatments of known efficacy for one disease process have consistent benefits for the other. Observational studies have yielded variable estimates of the effect of statin therapy on the risk of venous thromboembolism, and evidence from randomized trials is lacking. METHODS: We randomly assigned 17,802 apparently healthy men and women with both low-density lipoprotein (LDL) cholesterol levels of less than 130 mg per deciliter (3.4 mmol per liter) and high-sensitivity C-reactive protein levels of 2.0 mg per liter or higher to receive rosuvastatin, 20 mg per day, or placebo. We followed participants for the first occurrence of pulmonary embolism or deep-vein thrombosis and performed analyses of the data on an intention-to-treat basis. RESULTS: During a median follow-up period of 1.9 years (maximum, 5.0), symptomatic venous thromboembolism occurred in 94 participants: 34 in the rosuvastatin group and 60 in the placebo group. The rates of venous thromboembolism were 0.18 and 0.32 event per 100 person-years of follow-up in the rosuvastatin and placebo groups, respectively (hazard ratio with rosuvastatin, 0.57; 95% confidence interval [CI], 0.37 to 0.86; P=0.007); the corresponding rates for unprovoked venous thromboembolism (i.e., occurring in the absence of a known malignant condition, trauma, hospitalization, or surgery) were 0.10 and 0.17 (hazard ratio, 0.61; 95% CI, 0.35 to 1.09; P=0.09) and for provoked venous thromboembolism (i.e., occurring in patients with cancer or during or shortly after trauma, hospitalization, or surgery), 0.08 and 0.16 (hazard ratio, 0.52; 95% CI, 0.28 to 0.96; P=0.03). The rates of pulmonary embolism were 0.09 in the rosuvastatin group and 0.12 in the placebo group (hazard ratio, 0.77; 95% CI, 0.41 to 1.45; P=0.42), whereas the rates of deep-vein thrombosis only were 0.09 and 0.20, respectively (hazard ratio, 0.45; 95% CI, 0.25 to 0.79; P=0.004). Consistent effects were observed in all the subgroups examined. No significant differences were seen between treatment groups in the rates of bleeding episodes. CONCLUSIONS: In this trial of apparently healthy persons, rosuvastatin significantly reduced the occurrence of symptomatic venous thromboembolism. (ClinicalTrials.gov number, NCT00239681.)

Endothelial progenitor cell mobilization and platelet microparticle release are influenced by clopidogrel plasma levels in stable coronary artery disease.

BACKGROUND: Increased numbers of endothelial (EMP) and platelet (PMP) microparticles have been related to cardiovascular risk factors and coronary artery disease. Little is known about the early effects of statins and clopidogrel on these new biomarkers of vascular homeostasis. The aim of the present study was to evaluate pharmacokinetic interactions between atorvastatin and clopidogrel and their effects, alone or combined, on EMP, PMP, and endothelial progenitor cells (EPC). METHODS AND RESULTS: A prospective open-label study enrolled subjects with stable coronary disease (n=26). Drugs were given daily for 3 weeks (atorvastatin 80 mg, visits 1-3; clopidogrel 75 mg, visits 2-4). Counts of EPC (CD34+/CD133+/KDR+), EMP (CD51+) and PMP (CD42+/CD31+), and pharmacokinetic parameters over 24h were assessed at each visit. Atorvastatin plasma concentrations were increased by concomitant therapy with clopidogrel (maximum serum concentration [C(max)], P=0.002; area under the clopidogrel or atorvastatin plasma concentration vs. time curve from 0 to the last detectable concentration [AUC(last)], P=0.03). After atorvastatin withdrawal there was an increase in clopidogrel plasma concentrations (C(max), P=0.009; AUC(last), P=0.039). PMP were inversely correlated with clopidogrel C(max) on visit 3 (rho=-0.57, P=0.006) and on visit 4 (rho=-0.54, P=0.01), and with clopidogrel AUC(last) on visit 3 (rho=-0.44, P=0.04), and on visit 4 (rho=-0.57, P=0.005). In addition, clopidogrel C(max) was correlated with EPC (CD133+/KDR+) on visit 4 (rho=0.48, P=0.025). No correlations of atorvastatin and MP or EPC were found. CONCLUSIONS: The balance between platelet MP release and EPC mobilization seems influenced by clopidogrel plasma levels, suggesting a protective mechanism on coronary artery disease.

Changes in lipoproteins associated with lipid-lowering and antiplatelet strategies in patients with acute myocardial infarction.

BACKGROUND: Despite lipid-lowering and antiplatelet therapy, the pattern of residual lipoproteins seems relevant to long-term cardiovascular outcomes. This study aims to evaluate the effects of combined therapies, commonly used in subjects with acute myocardial infarction, in the quality of low-density lipoprotein (LDL) particles. METHODS: Prospective, open-label trial, included patients with acute myocardial infarction. Patients were randomized to antiplatelet treatment (ticagrelor or clopidogrel) and subsequently to lipid-lowering therapy (rosuvastatin or simvastatin/ezetimibe) and were followed up for six months. Nonlinear optical properties of LDL samples were examined by Gaussian laser beam (Z-scan) to verify the oxidative state of these lipoproteins, small angle X-ray scattering (SAXS) to analyze structural changes on these particles, dynamic light scattering (DLS) to estimate the particle size distribution, ultra violet (UV)-visible spectroscopy to evaluate the absorbance at wavelength 484 nm (typical from carotenoids), and polyacrylamide gel electrophoresis (Lipoprint) to analyze the LDL subfractions. RESULTS: Simvastatin/ezetimibe with either clopidogrel or ticagrelor was associated with less oxidized LDL, and simvastatin/ezetimibe with ticagrelor to lower cholesterol content in the atherogenic subfractions of LDL, while rosuvastatin with ticagrelor was the only combination associated with increase in LDL size. CONCLUSIONS: The quality of LDL particles was influenced by the antiplatelet/lipid-lowering strategy, with ticagrelor being associated with the best performance with both lipid-lowering therapies. Trial registration: NCT02428374.

Prognostic role of neutrophil-to-lymphocyte ratio in patients with ST-elevation myocardial infarction undergoing to pharmaco-invasive strategy.

OBJECTIVES: We sought to determine the relationship between in-hospital mortality and the neutrophil-to-lymphocyte ratio (NLR) in patients with ST-elevation myocardial infarction (STEMI) undergoing with pharmaco-invasive strategy (PIS). BACKGROUND: Increased levels of white blood cells have been associated with adverse clinical outcomes in patients with (STEMI). NLR has recently emerged as a potent and more specific prognostic marker in predicting short- and long-term mortalityin patients undergoing primary percutaneous coronary intervention. This association has never been reported in patients managed with PIS. METHODS: Between March 2010 and October 2016, 1860 STEMI patients managed with PIS were consecutively included in a dedicated database. The study population was divided into tertiles based on the admission NLR values (lower: <4.0, intermediate: 4.0 to <7.3, and upper: ≥7.3). Co-primary endpoints were in-hospital mortality and MACE (death, non-fatal reinfarction or stent thrombosis). RESULTS: Patients in the upper NLR tertile had significantly higher in-hospital mortality (9.0% vs. 4.8% versus. 1.8%, p < 0.001) and MACE (11.6% vs. 8.0% versus 2.9%, p < 0.001) than patients with intermediate or low NLR. By multivariable logistic regression analysis, the upper NLR tertile was an independent predictor of MACE (odds radio [OR] 4.19, 95% confidence interval [95% CI] 2.23-7.88, p < 0.001) and in-hospital mortality [OR 3.32, 95% CI 1.19-9.28, p = 0.02]. CONCLUSION: High NLR values were independently associated with in-hospital MACE and death in STEMI patients submitted to a PIS. NLR might be a simple and useful risk stratification tool in this high-risk population.

Pharmaco-invasive Strategy in Myocardial Infarction: Descriptive Analysis, Presentation of Ischemic Symptoms and Mortality Predictors. / Estratégia Fármaco-Invasiva no Infarto do Miocárdio: Análise Descritiva, Apresentação de Sintomas Isquêmicos e Preditores de Mortalidade.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) is defined by symptoms accompanied by typical electrocardiogram changes. However, the characterization of ischemic symptoms is unclear, especially in subgroups such as women and the elderly. OBJECTIVES: To analyze the typification of ischemic symptoms, temporal metrics and observe the occurrence of in-hospital outcomes, in the analysis of predictive scores, in patients with STEMI, in a drug-invasive strategy. METHODS: Study involving 2,290 patients. Types of predefined clinical presentations: typical pain, atypical pain, dyspnea, syncope. We measured the time between the onset of symptoms and demand for care and the interval between arrival at the medical unit and thrombolysis. Odds-ratios (OR; CI-95%) were estimated in a regression model. ROC curves were constructed for mortality predictors. The adopted significance level (alpha) was 5%. RESULTS: Women had a high prevalence of atypical symptoms; longer time between the onset of symptoms and seeking care; delay between arrival at the emergency room and fibrinolysis. Hospital mortality was 5.6%. Risk prediction by Killip-Kimball classification: AUC: [0.77 (0.73-0.81)] in class ≥II. Subgroups studied [OR (CI-95%)]: women [2.06 (1.42-2.99); p=0.01]; chronic renal failure [3.39 (2.13-5.42); p<0.001]; elderly [2.09 (1.37-3.19) p<0.001]; diabetics [1.55 (1.04-2.29); p=0.02]; obese 1.56 [(1.01-2.40); p=0.04]: previous stroke [2.01 (1.02-3.96); p=0.04] correlated with higher mortality rates. CONCLUSION: Despite higher mortality rates in some subgroups, significant disparity persists in women, with delays in symptom recognition and prompt thrombolysis. We highlight the applicability of the Killip-Kimball score in prediction, regardless of the clinical presentation.

FUNDAMENTO: O infarto do miocárdio com elevação do segmento-ST (IAMCSST) é definido por sintomas acompanhados por alterações típicas do eletrocardiograma. Entretanto, a caracterização dos sintomas isquêmicos não é clara, principalmente em subgrupos, como mulheres e idosos. OBJETIVOS: Analisar a tipificação dos sintomas isquêmicos, métricas temporais e observar a ocorrência de desfechos intra-hospitalares, em análise dos escores preditivos, em pacientes com IAMCSST, em estratégia fármaco-invasiva. MÉTODOS: Estudo envolvendo 2.290 pacientes. Tipos de apresentações clínicas pré-definidas: dor típica, dor atípica, dispnéia, sincope. Medimos o tempo entre o início dos sintomas à demanda pelo atendimento e o intervalo entre a chegada à unidade-médica e trombólise. Odds-ratios (OR; IC-95%) foram estimadas em modelo de regressão. Curvas ROCs foram construídas para preditores de mortalidade. Nível de significância adotado (alfa) foi de 5%. RESULTADOS: Mulheres apresentaram alta prevalência de sintomas atípicos; maior tempo entre o início dos sintomas e a procura por atendimento; atraso entre a chegada ao pronto-socorro e a fibrinólise. A mortalidade hospitalar foi de 5,6%. Predição de risco pela classificação Killip-Kimball: AUC: [0,77 (0,73-0,81)] em classe ≥II. Subgrupos estudados [OR (IC-95%)]: mulheres [2,06 (1,42-2,99); p=0,01]; insuficiência renal crônica [3,39 (2,13-5,42); p<0,001]; idosos [2,09 (1,37-3,19) p<0,001]; diabéticos [1,55 (1,04-2,29); p=0,02]; obesos 1,56 [(1,01-2,40); p=0,04]; acidente vascular cerebral prévio [2,01 (1,02-3,96); p=0,04] correlacionaram-se com maiores taxas de mortalidade. CONCLUSÃO: Apesar das mais altas taxas de mortalidade em alguns subgrupos, disparidade significativa persiste nas mulheres, com atrasos no reconhecimento dos sintomas e trombólise imediata. Destaca-se a aplicabilidade do escore Killip-Kimball na predição, independentemente da apresentação clínica.

Rosuvastatin to prevent vascular events in men and women with elevated C-reactive protein.

BACKGROUND: Increased levels of the inflammatory biomarker high-sensitivity C-reactive protein predict cardiovascular events. Since statins lower levels of high-sensitivity C-reactive protein as well as cholesterol, we hypothesized that people with elevated high-sensitivity C-reactive protein levels but without hyperlipidemia might benefit from statin treatment. METHODS: We randomly assigned 17,802 apparently healthy men and women with low-density lipoprotein (LDL) cholesterol levels of less than 130 mg per deciliter (3.4 mmol per liter) and high-sensitivity C-reactive protein levels of 2.0 mg per liter or higher to rosuvastatin, 20 mg daily, or placebo and followed them for the occurrence of the combined primary end point of myocardial infarction, stroke, arterial revascularization, hospitalization for unstable angina, or death from cardiovascular causes. RESULTS: The trial was stopped after a median follow-up of 1.9 years (maximum, 5.0). Rosuvastatin reduced LDL cholesterol levels by 50% and high-sensitivity C-reactive protein levels by 37%. The rates of the primary end point were 0.77 and 1.36 per 100 person-years of follow-up in the rosuvastatin and placebo groups, respectively (hazard ratio for rosuvastatin, 0.56; 95% confidence interval [CI], 0.46 to 0.69; P<0.00001), with corresponding rates of 0.17 and 0.37 for myocardial infarction (hazard ratio, 0.46; 95% CI, 0.30 to 0.70; P=0.0002), 0.18 and 0.34 for stroke (hazard ratio, 0.52; 95% CI, 0.34 to 0.79; P=0.002), 0.41 and 0.77 for revascularization or unstable angina (hazard ratio, 0.53; 95% CI, 0.40 to 0.70; P<0.00001), 0.45 and 0.85 for the combined end point of myocardial infarction, stroke, or death from cardiovascular causes (hazard ratio, 0.53; 95% CI, 0.40 to 0.69; P<0.00001), and 1.00 and 1.25 for death from any cause (hazard ratio, 0.80; 95% CI, 0.67 to 0.97; P=0.02). Consistent effects were observed in all subgroups evaluated. The rosuvastatin group did not have a significant increase in myopathy or cancer but did have a higher incidence of physician-reported diabetes. CONCLUSIONS: In this trial of apparently healthy persons without hyperlipidemia but with elevated high-sensitivity C-reactive protein levels, rosuvastatin significantly reduced the incidence of major cardiovascular events. (ClinicalTrials.gov number, NCT00239681.)

Race, ethnicity, and the efficacy of rosuvastatin in primary prevention: the Justification for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin (JUPITER) trial.

OBJECTIVES: The aim of this study was to evaluate the effect of statin treatment in primary prevention of cardiovascular events in different race/ethnic groups. BACKGROUND: Clinical trial evidence about the efficacy of statins in the primary prevention of cardiovascular events among nonwhites is uncertain. METHODS: JUPITER trial, a randomized, double-blind, placebo-controlled evaluation of rosuvastatin 20 mg in the primary prevention of myocardial infarction (MI), stroke, arterial revascularization, hospitalization for unstable angina, and cardiovascular death included 12,683 whites and 5,117 nonwhites with low-density lipoprotein levels <130 mg/dL and high-sensitivity C-reactive protein levels ≥2.0 mg/L. RESULTS: Random allocation to rosuvastatin resulted in a 45% reduction in the primary end point among whites (hazard ratio [HR] 0.55, 95% CI 0.43-0.69) and a 37% reduction among nonwhites (HR 0.63, 95% CI 0.41-0.99). Blacks (HR 0.65, 95% CI 0.35-1.22) and Hispanics (HR 0.58, 95% CI 0.25-1.39) had similar risk reductions. Among nonwhites in the placebo group, the stroke rate exceeded the MI rate (0.44 vs 0.20 per 100 person-years); an opposite pattern was observed among whites (0.31 vs 0.42 per 100 person-years). Nonwhites had higher death rates than whites (2.25 vs 0.93 per 100 person-years); however, all-cause mortality was similar at 20% with rosuvastatin treatment in both participant groups. CONCLUSIONS: When used in primary prevention among individuals with low-density lipoprotein <130 mg/dL and high-sensitivity C-reactive protein ≥2 mg/L, rosuvastatin significantly reduced first MI, stroke, arterial revascularization, hospitalization for unstable angina, and cardiovascular death among whites and nonwhites.

HIV-Infected Naïve Patients Exhibit Endothelial Dysfunction Concomitant with Decreased Natural Antibodies Against Defined Apolipoprotein B Autoantigens. / Pacientes Naïve Infectados por HIV Apresentam Disfunção Concomitante com Diminuição de Anticorpos Naturais contra Autoantígenos Derivados da Apolipoproteína B Definidos.

BACKGORUND: Traditional and HIV-defined risk factors may be associated with an increase in cardiovascular events. Recent studies have suggested that the humoral immune response to modified LDL may be associated with the process of atherosclerosis. OBJECTIVES: To evaluate the presence of anti-oxLDL and apolipoprotein B-derived peptides in the blood, and their association with the endothelial function in HIV-infection. METHODS: This study consecutively included subjects matched for age, gender, and demographic data in two groups: (1) HIV-infected and naïve for antiviral therapy and (2) uninfected individuals. Subclinical atherosclerosis was assessed by intimal-media thickness, using ultrasonography of the carotid arteries. Endothelial function was determined by flow-mediated dilatation (FMD) of the brachial artery by ultrasonography. Autoantibodies (IgM, IgG) anti-oxidized low-density lipoprotein (oxLDL), anti-apolipoprotein B-peptide fragments (ApoB-D and 0033G-Cys peptides), and cytokine levels were evaluated by ELISA. RESULTS: This study's results showed no difference in subclinical atherosclerosis between groups; however, HIV-infected subjects showed a lower FMD, when compared to non-infected subjects. Therefore, HIV-infected subjects showed higher levels of inflammatory cytokines, titers of IgG anti-oxLDL, and IgG anti-ApoB-D. In contrast, titers of IgM anti-ApoB-D were lower in HIV-infected individuals and associated with reduced endothelial functions. CONCLUSIONS: This study's results show that HIV infection, in naïve subjects, is associated with endothelial dysfunction and a decline of natural antibodies to apo-B antigens.

FUNDAMENTO: Fatores de risco definidos para HIV e tradicionais podem estar associados a um aumento de eventos cardiovasculares. Estudos recentes sugerem que a resposta imune humoral à LDL modificada pode estar associada ao processo de aterosclerose. OBJETIVOS: Avaliar a presença de anti-LDL oxidada e de peptídeos derivados da Apolipoproteína B no sangue, bem como sua associação à função endotelial na infecção por HIV. MÉTODOS: Este estudo incluiu consecutivamente sujeitos com idade, sexo e dados demográficos correspondentes em dois grupos: (1) indivíduos infectados com HIV e naïve para terapia antiviral e (2) indivíduos não infectados. A aterosclerose subclínica foi avaliada pela espessura íntima-média, utilizando-se a ultrassonografia das artérias carótidas. A função endotelial foi determinada pela dilatação mediada por fluxo (DMF) da artéria braquial por ultrassonografia. Os níveis de autoanticorpos (IgM, IgG) de lipoproteínas de baixa densidade antioxidadas (LDL-ox), fragmentos de peptídeos antiapolipoproteína B (peptídeos ApoB-D e 0033G-Cys), e citocina foram avaliados por meio de ELISA. RESULTADOS: Os resultados deste estudo não mostraram diferenças na aterosclerose subclínica entre os grupos. Entretanto, os sujeitos infectados com HIV apresentaram uma DMF mais baixa, em comparação com os sujeitos não infectados. Portanto, os sujeitos infectados com HIV apresentaram níveis mais altos de citocinas inflamatórias, títulos de IgG anti-LDL-ox, e IgG anti-ApoB-D. Em contraste, títulos de IgM anti-ApoB-D foram mais baixos em indivíduos infectados com HIV e associados a funções endoteliais diminuídas. CONCLUSÕES: Os resultados deste estudo mostram que a infecção por HIV, em sujeitos naïve, está associada à disfunção endotelial e à diminuição de anticorpos naturais para antígenos Apo-B.

Performance of the Electrocardiogram in the Diagnosis of Left Ventricular Hypertrophy in Older and Very Older Hypertensive Patients. / Desempenho do Eletrocardiograma no Diagnóstico da Hipertrofia Ventricular Esquerda em Hipertensos Idosos e Muito Idosos.

BACKGROUND: Left ventricular hypertrophy (LVH) is an important cardiovascular risk factor, regardless of arterial hypertension. Despite the evolution of imaging tests, the electrocardiogram (ECG) is still the most used in the initial evaluation, however, with low sensitivity. OBJECTIVE: To evaluate the performance of the main electrocardiographic criteria for LVH in elderly and very elderly hypertensive individuals. METHODS: In a cohort of hypertensive patients, ECGs and doppler echocardiographies (ECHO) were performed and separated into three age groups: <60 years, Group I; 60-79 years Group II; and ≥80 years, Group III. The most used electrocardiographic criteria were applied for the diagnosis of LVH: Perugia; Pegaro-Lo Presti; Gubner-Ungerleider; Narita; (Rm+Sm) x duration; Cornell voltage; Cornell voltage duration; Sokolow-Lyon voltage; R of aVL ≥11 mm; RaVL duration. In evaluating the performance of these criteria, in addition to sensitivity (Sen) and specificity (Esp), the "Diagnostic Odds Ratios" (DOR) were analyzed. We considered p-value <0.05 for the analyses, with two-tailed tests. RESULTS: In 2,458 patients, LVH was present by ECHO in 781 (31.7%). In Groups I and II, the best performances were for the criteria of Narita, Perugia, (Rm+Sm) x duration, with no statistical differences between them. In Group III (very elderly) the Perugia criteria and (Rm+Sm) x duration had the best performances: Perugia [44,7/89.3; (Sen/Esp)] and (Rm+Sm) duration [39.4%/91.3%; (Sen/Esp), p<0.05)], with the best PAIN results:6.8. This suggests that in this very elderly population, these criteria have greater discriminatory power to separate patients with LVH. CONCLUSION: In very elderly hypertensive patients, the Perugia electrocardiographic criteria and (Rm+Sm) x duration showed the best diagnostic performance for LVH.

FUNDAMENTO: A hipertrofia ventricular esquerda (HVE) é um importante fator de risco cardiovascular, independente da hipertensão arterial. Apesar da evolução dos exames de imagem, o eletrocardiograma (ECG) ainda é o mais utilizado na avaliação inicial, porém, com baixa sensibilidade. OBJETIVO: Avaliar o desempenho dos principais critérios eletrocardiográficos para HVE em indivíduos hipertensos idosos e muito idosos. MÉTODOS: Em coorte de hipertensos foram realizados ECGs e EcoDopplercardiogramas (ECO), e separados em três grupos etários: <60 anos, Grupo I; 60-79 anos Grupo II; e ≥80 anos, Grupo III. Os critérios eletrocardiográficos mais utilizados foram aplicados para o diagnóstico da HVE: Perúgia; Peguero-Lo Presti; Gubner-Ungerleider; Narita; (Rm+Sm) x duração; Cornell voltagem; Cornell voltagem duração; Sokolow-Lyon voltagem; R de aVL ≥11 mm; RaVL duração. Na avaliação do desempenho desses critérios, além da sensibilidade (Sen) e especificidade (Esp), foram analisadas as "Odds Ratios diagnóstico" (DOR). Consideramos p-valor <0,05 para as análises, com testes bi-caudais. RESULTADOS: Em 2.458 pacientes, a HVE estava presente pelo ECO em 781 (31,7%). Nos Grupos I e II, os melhores desempenhos foram para os critérios de Narita, Perúgia, (Rm+Sm) x duração, sem diferenças estatísticas entre eles. No Grupo III (muito idosos) os critérios de Perúgia e (Rm+Sm) x duração tiveram os melhores desempenhos: Perúgia [44,7/89,3; (Sen/Esp)] e (Rm+Sm) duração [39,4%/91,3%; (Sen/Esp), p<0,05)], com os melhores resultados de DOR:6,8. Isto sugere que nessa população de muito idosos esses critérios têm maior poder discriminatório para separar pacientes com HVE. CONCLUSÃO: Nos hipertensos muito idosos os critérios eletrocardiográficos de Perúgia e (Rm+Sm) x duração apresentaram os melhores desempenhos diagnósticos para HVE.

Accuracy of Post-thrombolysis ST-segment Reduction as an Adequate Reperfusion Predictor in the Pharmaco-Invasive Approach. / Acurácia da Redução do Segmento-ST Pós-Trombólise como Preditor de Reperfusão Adequada em Estratégia Fármaco-Invasiva.

BACKGROUND: Primary percutaneous coronary intervention is considered the "gold standard" for coronary reperfusion. However, when not available, the drug-invasive strategy is an alternative method and the electrocardiogram (ECG) has been used to identify reperfusion success. OBJECTIVES: Our study aimed to assess ST-Segment changes in post-thrombolysis and their power to predict recanalization and using the angiographic scores TIMI-flow and Myocardial Blush Grade (MBG) as an ideal reperfusion criterion. METHODS: 2,215 patients with ST-Segment Elevation Myocardial Infarction (STEMI) undergoing fibrinolysis [(Tenecteplase)-TNK] and referred to coronary angiography within 24 h post-fibrinolysis or immediately referred to rescue therapy were studied. The ECG was performed pre- and 60 min-post-TNK. The patients were categorized into 2 groups: those with ideal reperfusion (TIMI-3 and MBG-3) and those with inadequate reperfusion (TIMI and MBG <3). The ECG reperfusion criterion was defined by the reduction of the ST-Segment >50%. A p-value <0.05 was considered for the analyses, with bicaudal tests. RESULTS: The ECG reperfusion criterion showed a positive predictive value of 56%; negative predictive value of 66%; sensitivity of 79%; and specificity of 40%. There was a weak positive correlation between ST-Segment reduction and ideal reperfusion angiographic data (r = 0.21; p <0.001) and low diagnostic accuracy, with an AUC of 0.60 (95%CI: 0.57-0.62). CONCLUSION: The ST-Segment reduction was not able to accurately identify patients with adequate angiographic reperfusion. Therefore, even patients with apparently successful reperfusion should be referred to angiography soon, to ensure adequate macro and microvascular coronary flow.

FUNDAMENTO: A intervenção coronária percutânea primária é considerada o "padrão-ouro" para reperfusão coronária. Entretanto, quando não disponível, a estratégia fármaco-invasiva é método alternativo, e o eletrocardiograma (ECG) tem sido utilizado para identificar sucesso na reperfusão. OBJETIVOS: Nosso estudo teve como objetivo examinar alterações no segmento-ST pós-lise e seu poder de prever a recanalização, usando os escores angiográficos TIMI e blush miocárdio (MBG) como critério de reperfusão ideal. MÉTODOS: Foram estudados 2.215 pacientes com infarto agudo do miocárdio com supra-ST submetidos à fibrinólise [(Tenecteplase)-TNK] e encaminhados para angiografia coronária em até 24 h pós-fibrinólise ou imediatamente encaminhados à terapia de resgate. O ECG foi realizado pré-TNK e 60 min-pós. Os pacientes foram categorizados em dois grupos: aqueles com reperfusão ideal (TIMI-3 e MBG-3) e aqueles com reperfusão inadequada (fluxo TIMI <3). Foi definido o critério de reperfusão do ECG pela redução do segmento ST >50%. Consideramos p-valor <0,05 para as análises, com testes bicaudais. RESULTADOS: O critério de reperfusão pelo ECG apresentou valor preditivo positivo de 56%; valor preditivo negativo de 66%; sensibilidade de 79%; e especificidade de 40%. Houve fraca correlação positiva entre a redução do segmento-ST e os dados angiográficos de reperfusão ideal (r = 0,21; p <0,001) e baixa precisão diagnóstica, com AUC de 0,60 (IC-95%; 0,57-0,62). CONCLUSÃO: Em nossos resultados, a redução do segmento-ST não conseguiu identificar com precisão os pacientes com reperfusão angiográfica apropriada. Portanto, mesmo pacientes com reperfusão aparentemente bem-sucedida devem ser encaminhados à angiografia brevemente, a fim de garantir fluxo coronário macro e microvascular adequados.

Absence of Nocturnal Fall in Blood Pressure Detected by Ambulatory Blood Pressure Monitoring in Acute Chagas Disease Patients with Oral Infection. / Ausência de Descenso da Pressão Arterial Detectada pela Monitorização Ambulatorial da Pressão Arterial em Pacientes com Doença de Chagas Aguda Transmitida por Via Oral.

Background The involvement of the autonomic nervous system is one of the mechanisms proposed to explain the progression of myocardial lesion in Chagas disease. Evidences have shown changes in sympathetic and parasympathetic nervous system since the acute phase of the disease, and studies to clarify the pathophysiological and prognostic value of these changes are needed. Objetives To assess blood pressure profile by ambulatory blood pressure monitoring (ABPM) in normotensive patients with acute Chagas disease (ACD) without apparent cardiac damage, and the influence of the infection on nocturnal blood pressure fall. Methods ABPM was performed with 54 patients with ACD and a control group composed of 54 age- and sex-matched normotensive individuals. The alpha level of significance (type I error rate) was set at 5%. Results In the total of 54 patients, 74.0% did not show nocturnal fall in systolic blood pressure, 53.7% did not show nocturnal fall in diastolic blood pressure, and lack of both nocturnal fall in SBP and DBP was observed in 51.8% (*p<0.05). In 12.9% of patients, there was an increase in SBP and in 18.5% increase in DBP (p<0.05). Conclusions In patients with acute Chagas disease, a significant absence of the physiological fall in both systolic and diastolic blood pressure was observed during sleep, and some of the patients showed nocturnal increase in these parameters. These findings suggest autonomic changes in the acute phase of Chagas disease. (Arq Bras Cardiol. 2020; 114(4):711-715).

Early Changes in Circulating Interleukins and Residual Inflammatory Risk After Acute Myocardial Infarction. / Alterações Precoces nas Interleucinas Circulantes e no Risco Inflamatório Residual após Infarto Agudo do Miocárdio.

BACKGROUND: Patients with acute myocardial infarction may have a large infarcted area and ventricular dysfunction despite early thrombolysis and revascularization. OBJECTIVE: To investigate the behavior of circulating cytokines in patients with ST-segment elevation myocardial infarction (STEMI) and their relationship with ventricular function. METHODS: In the BATTLE-AMI (B and T Types of Lymphocytes Evaluation in Acute Myocardial Infarction) trial, patients with STEMI were treated with a pharmacoinvasive strategy. The plasma levels of cytokines (IL-1 ß , IL-4, IL-6, IL-10, and IL-18) were tested using enzyme-linked immunosorbent assay (ELISA) at baseline and after 30 days. Infarcted mass and left ventricular ejection fraction (LVEF) were examined by 3-T cardiac magnetic resonance imaging. All p-values < 0.05 were considered statistically significant. RESULTS: Compared to baseline, lower levels were detected for IL-1 ß (p = 0.028) and IL-18 (p < 0.0001) 30 days after STEMI, whereas higher levels were observed for IL-4 (p = 0.001) and IL-10 (p < 0.0001) at that time point. Conversely, no changes were detected for IL-6 levels (p = 0.63). The levels of high-sensitivity C-reactive protein and IL-6 correlated at baseline (rho = 0.45, p < 0.0001) and 30 days after STEMI (rho = 0.29, p = 0.009). At baseline, correlation between IL-6 levels and LVEF was also observed (rho = -0.50, p = 0.004). CONCLUSIONS: During the first month post-MI, we observed a marked improvement in the balance of pro- and anti-inflammatory cytokines, except for IL-6. These findings suggest residual inflammatory risk. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0).

FUNDAMENTO: Pacientes com infarto agudo do miocárdio podem apresentar uma grande área infartada e disfunção ventricular mesmo com trombólise e revascularização precoces. OBJETIVO: Investigar o comportamento das citocinas circulantes em pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST) e a relação delas com a função ventricular. MÉTODOS: No estudo BATTLE-AMI (Avaliação dos Linfócitos Tipos B e T no Infarto Agudo do Miocárdio), os pacientes com IAMCSST foram tratados com uma estratégia farmacoinvasiva. Os níveis de citocinas (IL-1ß, IL-4, IL-6, IL-10 e IL-18) no plasma foram testados através de ensaio de imunoadsorção enzimática (ELISA) no início do estudo e após 30 dias. A massa infartada e a fração de ejeção ventricular esquerda (FEVE) foram examinadas por ressonância magnética cardíaca 3-T. Valores de p menores que 0,05 foram considerados significativos. RESULTADOS: Na comparação com o início do estudo, níveis mais baixos foram detectados para IL-1ß (p = 0,028) e IL-18 (p < 0,0001) após 30 dias do IAMCSST, enquanto níveis mais altos foram observados para IL-4 (p = 0,001) e IL-10 (p < 0,0001) no mesmo momento. Em contrapartida, nenhuma mudança foi detectada nos níveis de IL-6 (p = 0,63). Os níveis da proteína C-reativa de alta sensibilidade e de IL-6 se correlacionaram no início do estudo (rho = 0,45, p < 0,0001) e 30 dias após o IAMCSST (rho = 0,29, p = 0,009). No início do estudo, a correlação entre os níveis de IL-6 e FEVE também foi observada (rho = -0,50, p = 0,004). CONCLUSÕES: Durante o primeiro mês pós-infarto agudo do miocárdio, observamos uma melhora significativa no balanço das citocinas pró e anti-inflamatórias, exceto da IL-6. Esses achados sugerem risco inflamatório residual. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0).

The Impact of Advanced Age on Major Cardiovascular Events and Mortality in Patients with ST-Elevation Myocardial Infarction Undergoing a Pharmaco-Invasive Strategy.

BACKGROUND: There is little research in the efficacy and safety of a pharmaco-invasive strategy (PIS) in patients ≥75 years versus <75 years of age. We aimed to evaluate and compare the influence of advanced age on the risk of death and major adverse cardiac events (MACE) in patients undergoing PIS. METHODS: Between January 2010 and November 2016, 14 municipal emergency rooms in São Paulo, Brazil, used full-dose tenecteplase to treat patients with STEMI as part of a pharmaco-invasive strategy for a local network implementation. RESULTS: A total of 1852 patients undergoing PIS were evaluated, of which 160 (9%) were ≥75 years of age. Compared to patients <75 years, those ≥75 years were more often female, had lower body mass index, higher rates of hypertension; higher incidence of hypothyroidism, chronic renal failure, prior stroke, and diabetes. Compared to patients <75 years of age, in-hospital MACE and mortality were higher in patients with ≥75 years (6.5% versus 19.4%; p<0.001; and 4.0% versus 18.2%; p<0.001, respectively). Patients ≥75 years had higher rates of in-hospital major bleeding (2.7% versus 5.6%; p=0.04) and higher incidence of cardiogenic shock (7.0% versus 19.6%; p<0.001). By multivariable analysis, age ≥75 years was independent predictor of MACE (OR 3.57, 95% CI 1.72 to 7.42, p=0.001) and death (OR 2.07, 95% CI 1.12-3.82, p=0.020). CONCLUSION: In patients with ST-segment elevation myocardial infarction undergoing PIS, age ≥75 years was an independent factor that entailed a 3.5-fold higher MACE and 2-fold higher mortality rate compared to patients <75 years of age.

Estratégia Farmacoinvasiva em Idosos até 75 Anos ou Não Idosos: Análise de Parâmetros Bioquímicos e de Ressonância Nuclear Magnética Cardíaca / Pharmacoinvasive Strategy in Elderly Up to 75 Years or Non-Elderly: Analysis of Biochemical and Cardiac Magnetic Resonance Imaging Parameters

Resumo Fundamento A estratégia farmacoinvasiva é uma alternativa na inviabilidade da intervenção coronária percutânea primária (ICP). Objetivos Este estudo teve como objetivo avaliar os efeitos da estratégia farmacoinvasiva precoce sobre o tamanho da área infartada e a fração de ejeção ventricular esquerda em pacientes idosos e não idosos. O papel dos marcadores inflamatórios também foi avaliado. Métodos Pacientes (n=223) com infarto do miocárdio com elevação do segmento ST (IAMCSST) foram prospectivamente incluídos e submetidos à trombólise medicamentosa nas primeiras seis horas, e à angiografia coronariana e à ICP, quando necessária, nas primeiras 24 horas. As amostras de sangue foram coletadas no primeiro dia (D1) e 30 dias após (D30). A ressonância magnética cardíaca foi realizada no D30. O nível de significância estatística foi estabelecido em p<0,05. Resultados Pacientes idosos e não idosos apresentaram porcentagem similares de massa infartada [13,7 (6,9-17,0) vs. 14,0 (7,3-26,0), respectivamente p=0,13)] [mediana (intervalo interquartil)]. No entanto, os pacientes idosos apresentaram maior fração de ejeção ventricular esquerda [53 (45-62) vs. 49 (39-58), p=0,025)]. As concentrações de interleucina (IL)1beta, IL-4, IL-6, e IL-10 não foram diferentes entre D1 e D30, mas pacientes idosos apresentaram níveis mais elevados de IL-18 em D1 e D30. O número absoluto de linfócitos B e T foram similares em ambos os grupos em D1 e D30, porém, pacientes idosos apresentaram uma razão neutrófilo-linfócito mais alta em D30. A análise de regressão linear multivariada dos desfechos de RMC de toda a população do estudo mostrou que os preditores independentes não foram diferentes entre pacientes idosos e não idosos. Conclusão A estratégia farmacoinvasiva em pacientes idosos foi associada a pequenas diferenças nos parâmetros inflamatórios, tamanho do infarto similar, e melhor função ventricular esquerda em comparação a pacientes não idosos

Abstract Background Pharmacoinvasive strategy is an alternative when primary percutaneous coronary intervention (PCI) is not feasible. Objectives This study aimed to evaluate the effects of early pharmacoinvasive strategy on the infarct size and left ventricular ejection fraction in elderly and non-elderly patients. The role of inflammatory markers was also examined. Methods Patients (n=223) with ST segment elevation myocardial infarction (STEMI) were prospectively included and submitted to pharmacological thrombolysis in the first six hours, and underwent coronary angiogram and PCI when necessary, in the first 24 hours. Blood samples were collected in the first day (D1) and after 30 days (D30). Cardiac magnetic resonance imaging (cMRI) was performed at D30. Significance was set at p<0.05. Results Elderly and non-elderly patients showed similar percentage of infarcted mass (13.7 [6.9-17.0] vs. 14.0 [7.3-26.0], respectively, p=0.13) (median [interquartile range]). However, elderly patients had better left ventricular ejection fraction (53 [45-62] vs. 49 [39-58], p=0.025). Titers of interleukin (IL)1beta, IL-4, IL-6, and IL-10 did not differ between D1 and D30, but elderly patients had higher titers for IL-18 at D1 and D30. Absolute numbers of B and T lymphocytes were similar in both groups at D1 and D30, but elderly patients had higher neutrophil/lymphocyte ratio at D30. Multivariate linear regression analysis of cMRI outcomes in the whole population showed that the independent predictors were not different between elderly and non-elderly patients. Conclusion Pharmacoinvasive strategy in elderly patients was associated with small differences in inflammatory parameters, similar infarct size and better left ventricular function than non-elderly patients.
