Concentración de colesterol-HDL y riesgo de infección por SARS-CoV-2 en personas mayores de 75 años: una cohorte con medio millón de participantes de la Comunidad de Madrid / HDL-cholesterol concentration and risk of SARS-CoV-2 infection in people over 75 years of age: a cohort with half a million participants from the Community of Madrid

Objetivo: El objetivo de este estudio fue analizar la relación entre el colesterol-HDL y el riesgo de infección por SARS-CoV-2 en mayores de 75 años residentes en la Comunidad de Madrid. Métodos: Estudio de una cohorte de base poblacional, compuesto por todos los residentes en Madrid (España) nacidos antes del 1 de enero de 1945 y vivos el 31 de diciembre de 2019. Los datos demográficos, clínicos y analíticos se obtuvieron de las historias clínicas electrónicas de atención primaria desde enero de 2015. La infección confirmada por SARS-CoV-2 se definió como un resultado positivo en la RT-PCR o en la prueba de antígeno. Los datos sobre infección por SARS-CoV-2 corresponden al periodo del 1 de marzo de 2020 hasta el 31 de diciembre de 2020. Resultados: De los 593.342 participantes de la cohorte, 501.813 tenían al menos una determinación de colesterol-HDL en los últimos 5 años. Su edad media era 83,4±5,6 años y el 62,4% eran mujeres. Un total de 36.996 (7,4%) tuvieron una infección confirmada por SARS-CoV2 durante el año 2020. El riesgo de infección (odds ratio [intervalo de confianza 95%]) por SARS-CoV2 según los quintiles crecientes de colesterol-HDL fue de 1; 0,960 (0,915-1,007), 0,891 (0,848-0,935), 0,865 (0,824-0,909) y 0,833 (0.792-0,876), tras ajustar por edad, sexo, factores de riesgo cardiovascular y comorbilidades. Conclusiones: Existe una relación inversa y dosis-dependiente entre la concentración de colesterol-HDL y el riesgo de infección por SARS-CoV2 en los mayores de 75 años de la Comunidad de Madrid.

Influence of COPD systemic environment on the myogenic function of muscle precursor cells in vitro.

BACKGROUND: Loss of muscle mass and function are well-recognized systemic manifestations of chronic obstructive pulmonary disease (COPD). Acute exacerbations, in turn, significantly contribute to upgrade these systemic comorbidities. Involvement of myogenic precursors in muscle mass maintenance and recovery is poorly understood. The aim of the present study was to investigate the effects of the vascular systemic environment from stable and exacerbated COPD patients on the myogenic behavior of human muscle precursor cells (MPC) in vitro. METHODS: Serum from healthy controls and from stable and exacerbated COPD patients (before and after Methylprednisolone treatment) was used to stimulate human MPC cultures. Proliferation analysis was assessed through BrdU incorporation assays. MPC differentiation was examined through real-time RT-PCR, western blot and immunofluorescence analysis. RESULTS: Stimulation of MPCs with serum obtained from stable COPD patients did not affect myogenic precursor cell function. The vascular systemic environment during an acute exacerbation exerted a mitotic effect on MPCs without altering myogenic differentiation outcome. After Methylprednisolone treatment of acute exacerbated COPD patients, however, the mitotic effect was further amplified, but it was followed by a deficient differentiation capacity. Moreover, these effects were prevented when cells were co-treated with the glucocorticoid receptor antagonist Mifepristone. CONCLUSION: Our findings suggest that MPC capacity is inherently preserved in COPD patients, but is compromised after systemic administration of MP. This finding strengthens the concept that glucocorticoid treatment over the long term can negatively impact myogenic stem cell fate decisions and interfere with muscle mass recovery.

Pre-infection HDL-cholesterol levels and mortality among elderly patients infected with SARS-CoV-2.

BACKGROUND AND AIMS: Low HDL-cholesterol (HDLc) concentration is associated with a greater risk of infection-related mortality. We wanted to evaluate the relationship between pre-infection HDLc levels and mortality among older patients infected with SARS-Cov-2. METHODS: This is a population-based, cohort study, comprising all individuals residing in Madrid (Spain) born before 1 January 1945, and alive on 31 December 2019. Demographic, clinical, and analytical data were obtained from the primary care electronic clinical records. Confirmed SARS-CoV-2 infection was defined as a positive result in the RT-qPCR or in the antigen test. A death from COVID-19 was defined as that registered in the hospital chart, or as any death occurring in the 15 days following a confirmed SARS-CoV-2 infection. Data on infection, hospitalization, or death due to SAR-CoV-2 were collected from 1 March 2020 through 31 December 2020. RESULTS: Of the 593,342 individuals comprising the cohort, 36,966 had a SARS-CoV-2 infection during 2020, and at least one HDLc measurement in the previous five years. Among them, 9689 (26.2%) died from COVID-19. After adjustment for age and sex, the relative risk (95% confidence interval) of COVID-19 death across increasing quintiles of HDLc was 1.000, 0.896 (0.855-0.940), 0.816 (0.776-0.860), 0.758 (0.719-0.799), and 0.747 (0.708-0.787). The association was maintained after further adjustment for comorbidities, statin treatment and markers of malnutrition. While in females this association was linear, in males it showed a U-shaped curve. CONCLUSIONS: In older subjects, a higher HDLc measured before SARS-CoV-2 infection was associated with a lower risk of death.

Previously Undetected Obstructive Sleep Apnea in Patients With New-Onset Atrial Fibrillation.

Obstructive sleep apnea-hypopnea syndrome (OSA) compromises the efficacy of atrial fibrillation (AF) control strategies. Continuous positive airway pressure (CPAP) may ameliorate arrhythmia control especially in early AF stages (new-onset AF). We investigated a practical screening strategy to determine the likelihood of CPAP indication in new-onset AF patients. Seventy-seven consecutive patients with new-onset (<1 month) AF were prospectively evaluated. Of them, 4 were excluded due to previously diagnosed OSA. The remaining 73 (68% persistent AF) fulfilled the Epworth, Berlin and STOP-BANG questionnaires, an ambulatory polysomnography being performed thereafter in all them in order to determine the apnea-hipopnea index (AHI). CPAP was indicated following conventional criteria. The variables associated with the diagnosis of OSA, with the AHI value and with CPAP indication were investigated by means of descriptive, univariate and multivariate analysis. The prevalence of OSA of any degree and CPAP indication was 82% and 37%, respectively. The variables associated (p < 0.05) with a higher AHI were male gender, body mass index, obesity, hypertension, and high-risk scoring at the Berlin and STOP-BANG questionnaires. In the multivariate analysis, the STOP-BANG scoring proved superior to conventional risk factors and became the only variable predicting CPAP indication (odds ratio 4.5 [1.9 to 10.6]; p = 0.01), an optimized cutoff value of ≥4 being newly established (sensitivity/specificity 76/65%). In conclusion, in patients referred with new-onset AF we documented a high risk of OSA and of need for CPAP. A STOP-BANG scoring of ≥4 in our population was a practical screening alternative to direct polysomnography in this setting.

In-Home Diagnosis of Obstructive Sleep Apnea Using Automatic Video Analysis / Diagnóstico domiciliario de apnea obstructiva del sueño utilizando el análisis automático de vídeo

Study objectives: To evaluate the diagnostic accuracy of a non-invasive technology based on image processing for the identification of obstructive sleep apnea (OSA) and its severity at patients' home. METHODS: Observational, prospective, diagnostic accuracy study to evaluate the degree of measure agreement between Sleepwise (SW), in-laboratory attended polysomnography (PSG) and a home sleep apnea test (HSAT). 38 consecutive subjects with suspected OSA referred as outpatients to the sleep unit were recruited from September 2016 to September 2017. All patients underwent in-laboratory attended PSG and image processing with SW simultaneously overnight. Subsequently, a HSAT and image processing with SW were performed simultaneously overnight at patients' home, and the 2 nights after, patients underwent only image processing with SW consecutively. RESULTS: In-laboratory polysomnography and SW had a Lin's concordance correlation coefficient of 0.933 and a Kappa of 0.930. Between HSAT and SW the Lin's concordance correlation coefficient was 0.842 and a Kappa of 0.571. Agreement between two consecutive nights with SW recording showed a Lin's concordance correlation coefficient of 0.923 and a Kappa of 0. 837. CONCLUSIONS: SW was highly accurate for non-invasive and automatic diagnosis of OSA in outpatients compared to standard methods for OSA diagnosis either in-laboratory attended PSG or HSAT. SW proved to be a technique with repeatable and concordant results on different nights for the same patient. We conclude SW is a non-invasive, easy-to-use, portable, effective and highly accurate system for the in-home diagnosis of OSA

OBJETIVOS: Evaluar la precisión diagnóstica de una tecnología no invasiva basada en el procesamiento de imágenes para la identificación de la apnea obstructiva del sueño (AOS) y su gravedad en el domicilio de los pacientes. MÉTODOS: Estudio observacional, prospectivo y de precisión diagnóstica para evaluar el grado de concordancia entre las mediciones de Sleepwise (SW), polisomnografía (PSG) asistida en el laboratorio y poligrafía respiratoria domiciliaria (PRD). Se reclutaron 38 sujetos consecutivos con sospecha de AOS, referidos como pacientes ambulatorios a la unidad de sueño entre septiembre de 2016 y septiembre de 2017. Se les realizó a todos una PSG y procesamiento de imagen con SW durante la noche en el laboratorio. Posteriormente, se realizó una PRD y procesamiento de imágenes con SW de forma simultánea durante la noche en su domicilio, y las 2 noches siguientes los pacientes se sometieron solo a procesamiento de imágenes con SW. RESULTADOS: La polisomnografía en el laboratorio y el SW mostraron un coeficiente de correlación de concordancia de Lin de 0,933 y un Kappa de 0,930. Entre la PRD y el SW el coeficiente de correlación de concordancia de Lin fue de 0,842 y un Kappa de 0,571. La concordancia entre las 2 noches consecutivas de grabación con el SW mostró un coeficiente de correlación de concordancia de Lin de 0,923 y un Kappa de 0,837. CONCLUSIONES: El SW mostró alta precisión para el diagnóstico no invasivo y automatizado de la AOS en pacientes ambulatorios en comparación con los métodos estándar para el diagnóstico de la AOS, ya sean la PSG asistida en el laboratorio o la PRD. El SW demostró ser una técnica con resultados reproducibles y concordantes en diferentes noches para el mismo paciente. Concluimos que la SW es un sistema no invasivo, fácil de usar, portátil, eficaz y altamente preciso para el diagnóstico domiciliario de la AOS

Selección del tratamiento anticoagulante óptimo para el paciente con fibrilación auricular y diabetes o enfermedad renal crónica: papel del rivaroxabán / Selecting the best anticoagulant treatment for patients with atrial fibrillation and diabetes or chronic kidney disease: the role of rivaroxaban

Tanto la diabetes mellitus como la enfermedad renal crónica aumentan el riesgo de fibrilación auricular. A su vez, la concomitancia de diabetes mellitus y enfermedad renal crónica incrementa de manera sinérgica el riesgo tromboembólico asociado con la fibrilación auricular, lo que pone al paciente en esta situación en especial riesgo y obliga a no fijar nuestra actuación solo en la reducción del riesgo embólico, sino a buscar una protección general. Aunque todos los anticoagulantes orales reducen eficazmente el riesgo de ictus en el paciente diabético con fibrilación auricular, hay datos que indican que el rivaroxabán podría disminuir además la mortalidad cardiovascular en esta población, ofreciendo una protección adicional. Por otra parte, se ha descrito un empeoramiento de la función renal con el empleo de los antagonistas de la vitamina K (nefropatía por warfarina). En consecuencia, sería deseable que el tratamiento anticoagulante no solo disminuyera el riesgo de complicaciones tromboembólicas, sino que además no se asociara con este deterioro de la función renal. En este sentido, parece que algunos anticoagulantes orales de acción directa, como el dabigatrán y el rivaroxabán, tendrían un menor riesgo de eventos renales adversos en comparación con warfarina

Both diabetes mellitus and chronic kidney disease increase the risk of atrial fibrillation. In turn, the coexistence of diabetes and chronic kidney disease synergistically increases the thromboembolic risk associated with atrial fibrillation, which puts affected patients at a particularly high risk and makes it necessary to focus treatment not only on reducing the risk of embolism but also on providing more general prophylaxis. Although all oral anticoagulants are effective in reducing the risk of stroke in diabetic patients with atrial fibrillation, there are indications that rivaroxaban could also reduce cardiovascular mortality in this population, thereby providing additional benefits. Moreover, it has been reported that renal function deteriorates on vitamin K antagonist treatment (i.e. warfarin-related nephropathy). Consequently, the ideal anticoagulant treatment would decrease the risk of thromboembolic complications without also being associated with impaired renal function. In this context, it appears that some direct oral anticoagulants, such as dabigatran and rivaroxaban, may have a lower risk of adverse renal events than warfarin

Abordaje de la fibrilación auricular en pacientes con cáncer activo. Documento de consenso de expertos y recomendaciones / Atrial fibrillation in active cancer patients: expert position paper and recommendations

La mejora en la supervivencia de los pacientes con cáncer ha puesto de manifiesto el impacto clínico que la cardiotoxicidad tiene en el pronóstico tanto cardiovascular como onco-hematológico, sobre todo cuando motiva la interrupción de terapias antitumorales altamente eficaces. La fibrilación auricular es una complicación frecuente en pacientes con cáncer activo y su tratamiento supone un gran reto. Estos pacientes tienen mayores riesgos tromboembólico y hemorrágico y, sin embargo, no se dispone de escalas específicas para guiar la atención clínica. El objetivo de este documento promovido por los grupos de Cardio-Onco-Hematología y Trombosis de la Sociedad Española de Cardiología y elaborado de manera conjunta con las diferentes áreas de conocimiento de la Sociedad Española de Cardiología y con expertos de la Sociedad Española de Oncología Médica, la Sociedad Española de Oncología Radioterápica y la Sociedad Española de Hematología y Hemoterapia, es proporcionar un enfoque multidisciplinario y práctico para la prevención y el tratamiento de la fibrilación auricular de pacientes con cáncer activo y basado en el consenso de expertos

Improvements in survival among cancer patients have revealed the clinical impact of cardiotoxicity on both cardiovascular and hematological and oncological outcomes, especially when it leads to the interruption of highly effective antitumor therapies. Atrial fibrillation is a common complication in patients with active cancer and its treatment poses a major challenge. These patients have an increased thromboembolic and hemorrhagic risk but standard stroke prediction scores have not been validated in this population.

Differences in the ankle-brachial index in the general population after 4 years of follow-up.

BACKGROUND: Variation in the ankle-brachial index (ABI) is related to the progression of atherosclerosis in the lower extremities and is associated with mid-term cardiovascular morbidity and mortality. The aim of this study was to investigate the changes in ABI after four years of follow-up of individuals in the general population, and the factors associated with relevant variations observed. PATIENTS AND METHODS: The study was performed in 750 volunteers (mean age 69.9 years) men without any evidence of peripheral artery disease, who attended a primary care centre. A complete physical examination, together with standard blood tests and ABI were performed. Four years later a new clinical evaluation was done. Variations in ABI values were considered relevant if > 10 %. RESULTS: Mean ABI in the second visit was 1.07 ± 0.15, which represented 0.02 ± 0.12 points lower than in the first visit (P < 0.001). Of these subjects, 157 (21.6 %) had an ABI decrease > 10 %. Multivariate analysis showed that the change was associated with male gender, cardiovascular history, no intake of blockers of the renin-angiotensin system, and the presence of atherogenic dyslipidaemia. A relevant increase in ABI was observed in 117 subjects (16.1 %), but was not associated with any of the studied factors. CONCLUSIONS: ABI values tend to decrease in the general population, although one sixth of the studied subjects had a relevant increase in this parameter.

Patients at high risk of cerebrovascular disease: the REACH study.

Cerebrovascular disease is one of the leading causes of morbidity and mortality in developed countries. The identification of at-risk individuals is a high priority so that efficacious preventive measures can be implemented. Subjects with the highest risk of cerebrovascular diseases are those who already have had a stroke or a transient ischemic attack, and those with vascular disease in other territories, either in coronary or peripheral arteries. Other subjects at risk are those with cardiac disease, such as atrial fibrillation, those with hypertension, diabetes and smoking habit, as well as individuals with subclinical vascular disease. Although there is considerable evidence for the efficacy of preventive treatment in this population, the percentage of patients receiving optimum treatment is far from ideal. There is a need to implement strategies in the population directed towards increasing awareness of the need to establish healthy habits and adequate preventive pharmacological treatment that could reduce the incidence of this debilitating disease.

Factors associated with the discontinuation of evidence-based cardiovascular therapies in patients with stable coronary artery disease: a primary care perspective.

BACKGROUND: To identify factors associated with the discontinuation of evidence-based cardiovascular therapies after hospital discharge for a coronary event. DESIGN: Cross-sectional study carried out between June and October 2004 in 1799 primary care centers throughout Spain. PATIENTS AND METHODS: Eight thousand eight hundred and seventeen patients (73.7% males; 65.4 years) admitted for coronary disease causes in the past 6 months to 10 years and attending primary care postdischarge from hospital. Current medications, those prescribed at hospital discharge, and the development of adverse events, new risk factors, and comorbidities during follow-up, were collected from clinical records. RESULTS: After a median follow-up of 37.4 months, discontinuation rate of lipid-lowering agents, angiotensin renin system blockers, antiplatelet drugs, and beta-blockers were 7.2, 9.1, 10, and 20%, respectively. Of these, 10.8, 16.5, 9.9, and 20.1%, respectively, were because of adverse events. Factors associated with the discontinuation of lipid-lowering agents were the development of hypertension and diabetes during the follow-up. Discontinuation of antiplatelet drug was associated with an earlier history, or with de-novo occurrence, of atrial fibrillation. Discontinuation of angiotensin renin system blockers was associated with the development of atrial fibrillation, diabetes and hypercholesterolemia, and discontinuation of beta-blockers with de-novo appearance of peripheral artery disease, cerebrovascular disease, and heart failure. CONCLUSION: In patients followed-up in primary care, the discontinuation rate of cardiovascular disease medications was low and was mainly related to the development of adverse events together with new risk factors and comorbidities arising after hospital discharge.

[Clinical factors associated with inappropriate prescription of statins]. / Prescripción inadecuada de estatinas y factores clínicos asociados.

BACKGROUND AND OBJECTIVE: The aim of this study was to determine the percentage of subjects receiving statin treatment that was inappropriate and to evaluate the associated clinical factors. PATIENTS AND METHOD: A cross-sectional multi-centred study conducted across the Autonomous Regions of Spain. The appropriateness of prescription was based on the guidelines of the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) and the European Guidelines on Cardiovascular Disease Prevention. RESULTS: Of the 1,817 patients studied, 52.9% were male, the overall mean age was 59.4 years, 36% had cardiovascular disease and 32.7% had diabetes. In 90.8% of the population the prescription was correct according to at least one of the two guides being used, with a low concordance between them (kappa = 0.279). Almost 100% of subjects with cardiovascular disease or diabetes had an appropriate prescription. In primary prevention, 82.7% had an appropriate prescription according to at least one of the two guides used, but this percentage decreased to 20.7% when based on the European Guidelines. In multivariate analysis, there was agreement with both guides. The inappropriate prescription was directly, and significantly, associated with primary prevention and female gender, while being inversely related to age, smoking habit and LDL-cholesterol concentration. CONCLUSIONS: Most of the patients receiving statin treatment have an appropriate prescription, but the percentage of inappropriate prescription increases significantly in patients in primary prevention following European Guidelines.

Prescripción inadecuada de estatinas y factores clínicos asociados / Clinical factors associated with inappropriate prescription of statins

Fundamento y objetivo: El objetivo del estudio fue evaluar el porcentaje de sujetos en tratamiento con estatinas con una inadecuada prescripción, así como estudiar los factores asociados a ésta. Pacientes y método: Estudio transversal y multicéntrico en el que participaron 1.817 sujetos en tratamiento con estatinas procedentes de todas las comunidades autónomas. Se evaluó la indicación del tratamiento hipolipemiante según el National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) y las Guías Europeas para la Prevención de la Enfermedad Cardiovascular. Resultados: El 52,9% eran varones y la edad media fue de 59,4 años. Un 36,0% presentaba enfermedad cardiovascular y un 32,7% eran diabéticos. En un 90,8% del total de la población estaba correctamente indicado el tratamiento según al menos una de las 2 guías, con una baja concordancia entre ellas (* = 0,279). Aproximadamente en el 100% de los sujetos con enfermedad cardiovascular o diabetes la prescripción era adecuada. En prevención primaria, el tratamiento era adecuado en el 82,7% según al menos una de las 2 guías, si bien este porcentaje descendía hasta el 20,7% al aplicar las Guías Europeas. En el análisis multivariante ambas guías coincidían en que la prescripción inadecuada se asociaba directa y significativamente con estar en prevención primaria y el sexo femenino, e inversamente con la edad, el consumo de tabaco y la concentración de colesterol unido a lipoproteínas de baja densidad (cLDL). Conclusiones: En la mayoría de los pacientes tratados con estatinas la prescripción es adecuada, si bien el porcentaje de tratamientos inadecuados se incrementa sustancialmente en los pacientes en prevención primaria, especialmente con las Guías Europeas
