Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Guidelines on Cardiovascular Disease Prevention.

We present the Spanish adaptation of the 2021 European Guidelines on Cardiovascular Disease (CVD) prevention in clinical practice. The current guidelines besides the individual approach greatly emphasize on the importance of population level approaches to the prevention of cardiovascular diseases. Systematic global CVD risk assessment is recommended in individuals with any major vascular risk factor. Regarding LDL-Cholesterol, blood pressure, and glycemic control in patients with diabetes mellitus, goals and targets remain as recommended in previous guidelines. However, it is proposed a new, stepwise approach (Step 1 and 2) to treatment intensification as a tool to help physicians and patients pursue these targets in a way that fits patient profile. After Step 1, considering proceeding to the intensified goals of Step 2 is mandatory, and this intensification will be based on 10-year CVD risk, lifetime CVD risk and treatment benefit, comorbidities and patient preferences. The updated SCORE algorithm-SCORE2, SCORE-OP- is recommended in these guidelines, which estimates an individual's 10-year risk of fatal and non-fatal CVD events (myocardial infarction, stroke) in healthy men and women aged 40-89 years. Another new and important recommendation is the use of different categories of risk according different age groups (< 50, 50-69, ≥70 years). Different flow charts of CVD risk and risk factor treatment in apparently healthy persons, in patients with established atherosclerotic CVD, and in diabetic patients are recommended. Patients with chronic kidney disease are considered high risk or very high-risk patients according to the levels of glomerular filtration rate and albumin-to-creatinine ratio. New lifestyle recommendations adapted to the ones published by the Spanish Ministry of Health as well as recommendations focused on the management of lipids, blood pressure, diabetes and chronic renal failure are included.

Presentamos la adaptación española de las Guías Europeas de Prevención Cardiovascular 2021. En esta actualización además del abordaje individual, se pone mucho más énfasis en las políticas sanitarias como estrategia de prevención poblacional. Se recomienda el cálculo del riesgo vascular de manera sistemática a todas las personas adultas con algún factor de riesgo vascular. Los objetivos terapéuticos para el colesterol LDL, la presión arterial y la glucemia no han cambiado respecto a las anteriores guías, pero se recomienda alcanzar estos objetivos de forma escalonada (etapas 1 y 2). Se recomienda llegar siempre hasta la etapa 2, y la intensificación del tratamiento dependerá del riesgo a los 10 años y de por vida, del beneficio del tratamiento, de las comorbilidades, de la fragilidad y de las preferencias de los pacientes. Las guías presentan por primera vez un nuevo modelo para calcular el riesgo (SCORE2 y SCORE2 OP) de morbimortalidad vascular en los próximos 10 años (infarto de miocardio, ictus y mortalidad vascular) en hombres y mujeres entre 40 y 89 años. Otra de las novedades sustanciales es el establecimiento de diferentes umbrales de riesgo dependiendo de la edad (<50, 50-69, >70 años). Se presentan diferentes algoritmos de cálculo del riesgo vascular y tratamiento de los factores de riesgo vascular para personas aparentemente sanas, pacientes con diabetes y pacientes con enfermedad vascular aterosclerótica. Los pacientes con enfermedad renal crónica se considerarán de riesgo alto o muy alto según la tasa del filtrado glomerular y el cociente albúmina/creatinina. Se incluyen innovaciones en las recomendaciones sobre los estilos de vida, adaptadas a las recomendaciones del Ministerio de Sanidad, así como aspectos novedosos relacionados con el control de los lípidos, la presión arterial, la diabetes y la insuficiencia renal crónica.

Statement of the Spanish Interdisciplinary Vascular Prevention Committee on the updated European Cardiovascular Prevention Guidelines. / Comentario del CEIPV a la actualización de las Guías Europeas de Prevención Vascular en la Práctica Clínica.

We present the adaptation for Spain of the updated European Cardiovascular Prevention Guidelines. In this update, greater stress is laid on the population approach, and especially on the promotion of physical activity and healthy diet through dietary, leisure and active transport policies in Spain. To estimate vascular risk, note should be made of the importance of recalibrating the tables used, by adapting them to population shifts in the prevalence of risk factors and incidence of vascular diseases, with particular attention to the role of chronic kidney disease. At an individual level, the key element is personalised support for changes in behaviour, adherence to medication in high-risk individuals and patients with vascular disease, the fostering of physical activity, and cessation of smoking habit. Furthermore, recent clinical trials with PCSK9 inhibitors are reviewed, along with the need to simplify pharmacological treatment of arterial hypertension to improve control and adherence to treatment. In the case of patients with type 2 diabetes mellitus and vascular disease or high vascular disease risk, when lifestyle changes and metformin are inadequate, the use of drugs with proven vascular benefit should be prioritised. Lastly, guidelines on peripheral arterial disease and other specific diseases are included, as is a recommendation against prescribing antiaggregants in primary prevention.

Presentamos la adaptación para España de la actualización de las Guías Europeas de Prevención Vascular. En esta actualización se hace mayor énfasis en el abordaje poblacional, especialmente en la promoción de la actividad física y de una dieta saludable mediante políticas alimentarias y de ocio y transporte activo en España. Para estimar el riesgo vascular, se destaca la importancia de recalibrar las tablas que se utilicen, adaptándolas a los cambios poblaciones en la prevalencia de los factores de riesgo y en la incidencia de enfermedades vasculares, con particular atención al papel de la enfermedad renal crónica. A nivel individual resulta clave el apoyo personalizado para el cambio de conducta, la adherencia a la medicación en los individuos de alto riesgo y pacientes con enfermedad vascular, la promoción de la actividad física y el abandono del hábito tabáquico. Además, se revisan los ensayos clínicos recientes con inhibidores de PCKS9, la necesidad de simplificar el tratamiento farmacológico de la hipertensión arterial para mejorar su control y la adherencia al tratamiento. En los pacientes con diabetes mellitus 2 y enfermedad vascular o riesgo vascular alto, cuando los cambios de estilo de vida y la metformina resultan insuficientes, deben priorizarse los fármacos con demostrado beneficio vascular. Por último, se incluyen pautas sobre enfermedad arterial periférica y otras enfermedades específicas, y se recomienda no prescribir antiagregantes en prevención primaria.

[Response to hypoxia. A systemic mechanism based on the control of gene expression]. / Respuesta a la hipoxia. Un mecanismo sistemico basado en el control de la expresion genica.

New, critically important data have been recently generated about the response to hypoxia. This response can be schematized in three main systems or functions, ie, detectional or oxygen sensing, regulatory, which controls gene expression and effector. The principal organizer of the regulatory branch is a specific transcription factor, the hypoxia-inducible factor 1 (HIF-1). In the presence of oxygen, the alpha subunit of HIF-1 (HIF-1alpha) is modified by hydroxylases, that represent the central point of the oxygen sensing mechanism. This type of hydroxylation induces HIF-1alpha catabolism by the proteosome. On the contrary, in hypoxia, or in the presence of certain growth factors that increase HIF-1alpha synthesis, HIF-1alpha translocates to the nucleus, where it binds HIF-1beta, and thence acts on transcription of genes carrying hypoxia responsive elements (HRE) on their promoters. These genes regulate the synthesis of an ample series of proteins, which span from respiratory enzymes and transporters to hormones regulating circulation and erythropoiesis. The role of HIF-1alpha is not restricted to the mere induction of adaptation to decreased oxygen: instead, it significantly participates in cell repairing mechanisms. A simple list of some of the stimulatory or inhibitory alterations of pathophysiological importance involving the HIF-1 system, would include: chronic lung disease, smoking adaptation, anemia/hemorrhage, ischemia/reperfusion, growth, vascularization and cell resistance of tumors, preeclampsia and intrauterine growth retardation, retinal hyper o hypovascularization, drug intoxications, bowel inflammatory disease and wound repair. This list illustrates by itself the importance of the mechanism herein reviewed.

Respuesta a la hipoxia: un mecanismo sistemico basado en el control de la expresion genica / Response to hypoxia: a systemic mechanism based on the control of gene expression

La respuesta hipóxica, sobre la que se dispone de nuevos datos críticamente importantes, puede esquematizarse en tres sistemas, vg. de detección o sensor de oxígeno, de regulación, que controla la expresión génica y efector. El elemento principal de organización del sistema regulador es un factor de transcripción específico, el factor inducible por hipoxia 1 (HIF-1). En presencia de oxígeno, la subunidad α del HIF-1 (HIF-1α) se modifica por las hidroxilasas, que constituyen el punto central del mecanismo sensor, induciendo su catabolismo por el proteosoma. Por el contrario, en hipoxia, o en presencia de algunos factores de crecimiento que incrementan su síntesis, el HIF-1α se transloca al núcleo, donde, unido al HIF-1β, actúa como factor transcripcional de genes con elementos de respuesta hipóxica (HRE) en su promotor. Estos regulan lasíntesis de una amplia serie de proteínas, que abarcan desde enzimas respiratorias y transportadores hasta hormonas involucradas en la regulación a escala del organismo de la circulación y la eritropoyesis. El papel del HIF-1 no se restringe a la mera inducción de una respuesta adaptativa a la falta de oxígeno, sino que participa significativamente en los mecanismos de reparación celular. Una simple lista de algunas alteraciones de importância fisiopatológica, tanto estimulatorias como inhibitorias, que involucran al sistema de HIF-1, incluiría: enfermedad pulmonar crónica, adaptación al tabaco/humo, anemia/hemorragia, isquemia/reperfusión, crecimiento, vascularización y resistencia celular de los tumores, preeclampsia y crecimiento intrauterino retardado, hiper o hipovascularización retiniana, sobredosis de fármacos, enfermedad inflamatoria intestinal y curación de heridas. Esta sola enumeración ilustra la importancia de este mecanismo. .
