    Abstract Background: Despite widespread usage of central blood pressure assessment its predictive value among elderly people remains unclear.
    Objective: To ascertain the capacity of central hemodynamic indices for predicting future all-cause and cardiovascular hard outcomes among elderly people.
    Design and setting: Systematic review and meta-analysis developed at the Del Cuore cardiology clinic, in Antonio Prado, Rio Grande do Sul, Brazil.
    Methods: 312 full-text articles were analyzed, from which 35 studies were included for systematic review. The studies included needed to report at least one central hemodynamic index among patients aged 60 years or over.
    Results: For all-cause mortality, aortic pulse wave velocity (aPWV) and central systolic blood pressure (SBP) were significant, respectively with standardized mean difference (SMD) 0.85 (95% confidence interval, CI 0.69-1.01; I2 96%; P < 0.001); and SMD 0.27 (95% CI 0.15-0.39; I2 77%; P 0.012). For cardiovascular mortality brachial-ankle PWV (baPWV), central SBP and carotid-femoral PWV (cfPWV) were significant, respectively SMD 0.67 (95% CI 0.40-0.93; I2 0%; P 0.610); SMD 0.65 (95% CI 0.48- 0.82; I2 80%; P 0.023); and SMD 0.51 (95% CI 0.32-0.69; I2 85%; P 0.010).
    Conclusions: The meta-analysis results showed that aPWV was promising for predicting all-cause mortality, while baPWV and central SBP demonstrated consistent results in evaluating cardiovascular mortality outcomes. Thus, the findings support usage of central blood pressure as a risk predictor for hard outcomes among elderly people.

    Abstract Background:: Hypertension is an important risk factor for cardiovascular outcomes. Primary health care (PHC) physicians should be prepared to act appropriately in the prevention of cardiovascular risk factors. However, the rates of patients with control of blood pressure (BP) remain low. The impact of the reclassification of high BP by 24-hour ambulatory BP monitoring (ABPM) can lead to different medical decisions in PHC.
    Objective:: To evaluate the agreement between the BP measured by a conventional method by PHC physicians and by 24-hour ABPM, considering different BP normal thresholds for the 24-hour ABPM according to the V Brazilian ABPM Guidelines and the European Society of Hypertension Guidelines.
    Methods:: A cross-sectional study including 569 hypertensive patients. The BP was initially measured by the PHC physicians and, later, by 24-hour ABPM. The BP measurements were obtained independently between the two methods. The therapeutic targets for the conventional BP followed the guidelines by the Eighth Joint National Committee (JNC 8), the V ABPM Brazilian Guidelines, and the 2013 European Hypertension Guidelines.
    Results:: There was an accuracy of 54.8% (95% confidence interval [95%CI] 0.51 - 0.58%) for the BP measured with the conventional method when compared with the 24-hour ABPM, with a sensitivity of 85% (95%CI 80.8 - 88.6%), specificity of 31.9% (95%CI 28.7 - 34.7%), and kappa value of 0.155, when considering the European Hypertension Guidelines. When using more stringent thresholds to characterize the BP as "normal" by ABPM, the accuracy was 45% (95%CI 0.41 - 0.47%) for conventional measurement when compared with 24-hour ABPM, with a sensitivity of 86.7% (95%CI 0.81 - 0.91%), specificity of 29% (95%CI 0.26 - 0.30%), and kappa value of 0.103.
    Conclusion:: The BP measurements obtained by PHC physicians showed low accuracy when compared with those obtained by 24-hour ABPM, regardless of the threshold set by the different guidelines.
    Fundamentos:: A hipertensão arterial sistêmica é um fator de risco importante para desfechos cardiovasculares. Médicos da atenção primária à saúde (APS) devem estar preparados para atuar adequadamente na prevenção de fatores de risco cardiovascular. No entanto, as taxas de pacientes com pressão arterial (PA) controlada continuam baixas. O impacto da reclassificação do diagnóstico de hipertensão pela utilização da monitorização ambulatorial da PA (MAPA) de 24 horas pode levar a diferentes decisões médicas na APS.
    Objetivo:: Avaliar a concordância entre as PAs medidas por método convencional por médicos da APS e por MAPA de 24 horas, considerando diferentes limiares de normalidade para a MAPA de 24 horas de acordo com as recomendações da V Diretriz Brasileira de MAPA e da Diretriz da Sociedade Europeia de Hipertensão.
    Métodos:: Estudo transversal com 569 pacientes hipertensos. A PA foi medida inicialmente por médicos da APS e, posteriormente, pela MAPA de 24 horas. As medidas foram obtidas de forma independente entre os dois métodos. Os alvos terapêuticos para a PA convencional seguiram as orientações do Eighth Joint National Committee (JNC 8), das V Diretrizes Brasileiras de MAPA e das Diretrizes Europeias de Hipertensão de 2013.
    Resultados:: Foi observada uma acurácia de 54,8% (intervalo de confiança de 95% [IC95%] 0,51 - 0,58%) para a PA aferida de forma convencional quando comparada à obtida com a MAPA de 24 horas, além de uma sensibilidade de 85% (IC95% 80,8 - 88,6%), especificidade de 31,9% (IC95% 28,7 - 34,7%) e kappa de 0,155, quando consideradas as Diretrizes Europeias de Hipertensão. Quando utilizados limiares mais rígidos para caracterizar a PA como "normal" pela MAPA, foi identificada uma acurácia de 45% (IC95% 0,41 - 0,47%) pela medida convencional quando comparada à obtida pela MAPA de 24 horas, além de uma sensibilidade de 86,7% (IC95% 0,81 - 0,91%), especificidade de 29% (IC95% 0,26 - 0,30%) e kappa de 0,103.
    Conclusão:: As medidas de PA avaliadas pelos médicos da APS apresentaram baixa acurácia quando comparadas às medidas pela MAPA de 24 horas, independente do limiar utilizado pelas diferentes diretrizes.

    Abstract Background: Central blood pressure is a factor that may predict cardiovascular events. However, its use in clinical practice is not well consolidated. Therefore, the aim of our study will be to summarize the use of central hemodynamic parameters to predict cardiovascular-related outcomes and all-cause mortality.
    Design and setting: Protocol for systematic review of longitudinal observational studies conducted in healthcare institutions, as presented in the studies included.
    Methods: We will perform a systematic search in the electronic databases MEDLINE (via PubMed), EMBASE and LILACS (via Virtual Health Library (VHL)), using health descriptors terms for elderly people and for hemodynamic indices of central blood pressure. We will include articles that evaluated hemodynamic indices and at least one of the following outcomes: all-cause mortality, total cardiovascular death, total non-cardiovascular death, myocardial infarction, stroke, coronary artery restenosis after percutaneous coronary intervention, revascularization and aortic syndromes. Two independent reviewers will conduct analysis on the abstracts selected and on the full-text articles. Two reviewers will independently perform data extraction and evaluate the methodological quality of the articles selected, and a third reviewer will evaluate any divergences. The methodological quality of the studies will be assessed in accordance with the ROBINS-I tool (Risk Of Bias In Non-randomized Studies of Interventions).
    Results and conclusions: Through this systematic review, we intend to summarize evidence that supports the use of central hemodynamic parameters for central blood pressure to diagnose and perform prognostics on arterial hypertension in elderly patients within clinical practice and predict future cardiovascular events in this population.

    Abstract Introduction: several studies have evaluated the utilization of lipid biomarkers in an attempt to correlate them with clinical cardiovascular events. Nevertheless, the investigation of clinical conditions under specific plasmatic levels of lipoproteins for long periods presents limitations due to inherent difficulties that are related to the follow-up of individuals throughout their lives. Better understanding of the clinical response and occasional resistance to the action of hypolipidemic drugs in several clinic scenarios is also necessary.
    Objectives: to determine the role of evaluation of single-nucleotide polymorphisms (SNPs) related to the metabolism of lipids, and its implications in different clinical scenarios.
    Methods: a search of the literature in English and Spanish languages was performed in Medline, Lilacs via Bireme, IBECS via Bireme, and Cochrane databases. The expected results included information regarding plasmatic lipid profile and SNPs, cardiovascular clinical outcomes and polymorphisms related to the effectiveness of statins in the treatment of hypercholesterolemia.
    Results: in order to perform this analysis, 19 studies were included from a total of 89 identified citations. The evaluation of the results suggests that low plasmatic levels of LDL-c are associated with a reduction in the risk of heart attacks, although this was not observed for the rise of plasmatic levels of HDL-c.
    Conclusion: polymorphisms in different populations and clinical perspectives may bring important contributions for a better understanding and adequacy of plasmatic lipoproteins aiming at reducing cardiovascular risk.

    Abstract Background: Although systemic arterial hypertension (SAH) is an important cardiovascular risk factor, blood pressure level control often remains inadequate. Assessment of adherence to antihypertensive treatment through 24-hour ambulatory blood pressure monitoring (ABPM) may represent an important aid in the search for BP control targets.
    Objective: To assess adherence to antihypertensive treatment and its association with BP values at 24-hour ABPM in hypertensive patients treated in primary health care (PHC) centers.
    Methods: We carried out a cross-sectional study of 143 hypertensive patients, who constituted a representative sample of patients from PHC centers in the town of Antonio Prado, RS. The Morisky-Green test was used to evaluate adherence and verify the number of medications used by patients, followed by 24-hour ABPM.
    Results: We observed that 65.7% of the sample was considered adherent to the proposed treatment, 20.3% were moderately adherent and only 14% were classified as non-adherent. Considering all the 143 patients evaluated, 79 (55.2%) were identified as having controlled hypertension (<130/80 mmHg) according to the 24-hour ABPM measurements, 64 (44.8%) were considered uncontrolled (>130/80 mmHg), 103 (72%) had absence of nocturnal BP dip and 60 (41.9%) were uncontrolled while awake.
    Conclusions: In this study, we observed a lack of adequate hypertension control with a consequent loss of opportunity for PHC professionals to adequately adjust the recommended BP control targets. This fact occurs in spite of proper adherence to antihypertensive treatment by patients in PHC centers.
