ABSTRACT
Resumen En esta revisión de la literatura presentamos diversos mecanismos terapéuticos para tratar la rigidez vascular en pacientes con enfermedad renal crónica. En el ámbito de la terapéutica no farmacológica la restricción de sodio y la indicación de dieta mediterránea han demostrado efectos benéficos, mientras que acerca de la indicación de actividad física aún no hay evidencia clara sobre su utilidad para disminuir la rigidez vascular en este grupo específico de pacientes. Es con el tratamiento farmacológico donde se evidencian los mayores beneficios, tanto en la rigidez vascular como en los eventos cardiovasculares asociados. Está ampliamente demostrada la efectividad de los inhibidores del sistema renina-angiotensina-aldosterona y de los fármacos antialdosterónicos para disminuir la presión y la rigidez arterial. Otras drogas, como los bloqueadores del receptor de endotelina, han demostrado sus efectos protectores sobre la pared arterial, aunque no están carentes de potenciales efectos adversos. También repasamos los resultados obtenidos con el uso de las nuevas drogas antidiabéticas, en particular los iSLGT2 y los aGLP-1, y su efecto sobre la presión arterial y la rigidez vascular, en particular en pacientes con enfermedad renal crónica. Se revisan además la utilidad de aquellas drogas con efecto sobre la cascada inflamatoria y sobre las calcificaciones vasculares, muy propensas durante los tratamientos sustitutivos de la función renal. Este trabajo se enfoca, en síntesis, en las diversas intervenciones terapéuticas sobre la rigidez arterial, con énfasis en la disminución de eventos cardiovasculares y de la mortalidad en pacientes con enfermedad renal crónica.
Abstract In this literature review we present various therapeutic alternatives for vascular stiffness in patients with chronic kidney disease. Here we discussed the role of non-pharmacological treatments with evidence of the benefit of sodium restriction on vascular stiffness, the positive effects in that sense shown by the Mediterranean diet, and the small benefits of physical activity on vascular stiffness in this group of patients. Is in the pharmacological treatment where the best benefits are evidenced; both, on vascular stiffness and on the associated cardiovascular events. The effectiveness of renin-angiotensin-aldosterone system inhibitors and antialdosteronic drugs to decrease blood pressure and stiffness has been widely demonstrated. Other drugs, such as endothelin receptor blockers, showed their protective effects on the arterial wall, but with potential adverse effects. This article also reviews the effects of new anti-diabetic drugs, iSLGT2 and aGLP-1 in particular, and their effect on blood pressure and vascular stiffness, particularly in patients with chronic kidney disease. The utility of drugs with effects on the inflammatory cascade and drugs with a potential effect on vascular calcification, complication occurring frequently during renal function replacement treatment, are also reviewed. In short, this work focuses in the therapeutic interventions on arterial stiffness, with emphasis on the reduction of cardiovascular events and mortality in patients with chronic kidney disease.
ABSTRACT
ABSTRACT Introduction: Rheumatoid arthritis is an autoimmune disease that causes systemic involvement and is associated with increased risk of cardiovascular disease. Objective: To analyze the prediction index of 10-year risk of a fatal cardiovascular disease event in female RA patients versus controls. Methods: Case-control study with analysis of 100 female patients matched for age and gender versus 100 patients in the control group. For the prediction of 10-year risk of a fatal cardiovascular disease event, the SCORE and modified SCORE (mSCORE) risk indexes were used, as suggested by EULAR, in the subgroup with two or more of the following: duration of disease ≥10 years, RF and/or anti-CCP positivity, and extra-articular manifestations. Results: The prevalence of analyzed comorbidities was similar in RA patients compared with the control group (p > 0.05). The means of the SCORE risk index in RA patients and in the control group were 1.99 (SD: 1.89) and 1.56 (SD: 1.87) (p = 0.06), respectively. The means of mSCORE index in RA patients and in the control group were 2.84 (SD = 2.86) and 1.56 (SD = 1.87) (p = 0.001), respectively. By using the SCORE risk index, 11% of RA patients were classified as of high risk, and with the use of mSCORE risk index, 36% were at high risk (p< 0.001). Conclusion: The SCORE risk index is similar in both groups, but with the application of the mSCORE index, we recognized that RA patients have a higher 10-year risk of a fatal cardiovascular disease event, and this reinforces the importance of factors inherent to the disease not measured in the SCORE risk index, but considered in mSCORE risk index.
RESUMO Introdução: Artrite reumatoide (AR) é uma doença autoimune que determina manifestações sistêmicas e está associada a aumento do risco de evento cardiovascular. Objetivo: Analisar o índice SCORE de predição de evento cardiovascular em pacientes do gênero feminino portadores de AR comparados com controles sem a doença. Métodos: Estudo de caso-controle com análise de 100 pacientes pareadas por gênero e idade versus 100 pacientes do grupo controle. Para a predição do risco de evento cardiovascular fatal em 10 anos, usamos os índices SCORE e SCORE modificado (mScore), conforme sugerido pela Eular, no subgrupo com 2 ou mais dos seguintes: duração da doença ≥ 10 anos, positividade para fator reumatoide e/ou anti-CCP e manifestações extra-articulares. Resultados: A prevalência das comorbidades analisadas foi similar nas pacientes com AR, em comparação com o grupo controle (p > 0,05). As médias do índice SCORE foram 1,99 (DP: 1,89) e 1,56 (DP: 1,87) nas portadoras de AR e nos controles (p = 0,06), respectivamente. Com o uso do índice mScore, nas pacientes com AR foi encontrada a média de 2,84 (DP: 2,86) versus 1,56 nos controles (DP: 1,87) (p = 0,001). Ao usar o índice SCORE, 11% dos portadores de AR foram classificados como de alto risco; com o índice mScores, 36% obtiveram essa classificação (p < 0,001). Conclusões: O índice SCORE é semelhante nos dois grupos, mas com a aplicação do índice mScore identificamos que os pacientes com AR têm maior risco de evento cardiovascular fatal em 10 anos, com ênfase na importância dos fatores inerentes à doença não mensurados no índice SCORE, mas considerados no índice mScore.

background: Smoking is the leading cause of preventable morbidity and death. It is important to know the characteristics of smoking habits among physicians and their attitude toward patients who smoke. Objective: The aim of this study is to investigate the prevalence of smoking among physicians in Argentina, the factors associated with tobacco consumption and their attitude toward their patients who smoke. Methods: An observational cross- sectional study was performed between June and December 2013 in Argentine physicians of dif-ferent specialties. Using a structured survey, the following variables were analyzed: associated cardiovascular risk factors, charac-teristics of tobacco consumption, smoking cessation training and the attitude toward the patient who smokes. results: 3,033 physicians were surveyed, ; 57% were men, and mean age was 41.3±12 years; 19.7% were current smokers and 21.7% were former smokers. The probability of being a smoker was higher among surgeons (OR 1.29) or physicians working at the emergency room (OR 1.41). Undergraduate and postgraduate tobacco cessation training was achieved by 36.6% and 40.8% of physicians, respectively. Young physicians, clinical specialties or private practice were associated with higher level of training. Tobacco cessation counseling was more frequent in physicians with higher level of training than physicians who smoked or surgeons. Former smokers presented higher prevalence of risk factors and cardiovascular events. Family history of smoking habit was more common in former smokers and current smokers. Conclusions: The prevalence of smoking among Argentine physicians is high. Different factors are involved in the probability of smoking, tobacco cessation training or the possibility of medical counseling. Higher level of training in smoking cessation must be provided.
