[Asymptomatic peripheral arterial disease detected by the ankle-brachial index in HIV-infected patients: prevalence and associated risk factors]. / Enfermedad arterial periférica asintomática estimada mediante el índice tobillo-brazo en pacientes con infección por el VIH: prevalencia y factores de riesgo asociados.

INTRODUCTION: Human immunodeficiency virus (HIV) infection has been associated with a higher risk of subclinical atherosclerosis and cardiovascular events. Peripheral arterial disease (PAD) is a good marker of systemic atherosclerosis and a powerful predictor of cardiovascular morbidity and mortality. The objective of this study was to determine the prevalence of asymptomatic PAD and associated risk factors in HIV-infected people. METHODS: Cross-sectional study was conducted on all consecutive HIV-positive patients older than 20 years without symptoms of intermittent claudication who attended our clinic between November 2008 and December 2009. PAD was assessed by measuring the ankle-brachial index (ABI) at rest. To define PAD, an ABI ≤ 0.90 was used. Main epidemiological and clinical characteristics of the HIV infection and cardiovascular risk factors (CVRF) were recorded. RESULTS: Two hundred and five patients were evaluated (66.8% male), with a mean age of 41 years and there was a median of 2 CVRF (63.9% smokers). Prevalence of asymptomatic PAD (ABI ≤ 0.90) was 6.3% (n=13). There was only 1 patient with a high ABI (>1.40). In the multivariate analysis, factors significantly associated with PAD were overweight (adjusted odds ratio [ORadj] 4.21; 95% confidence interval [CI] 1.00-18.78), obesity (ORadj 5.76; 95% CI 1.17-28.37) and clinical stage C of HIV infection (ORadj 2.95; 95% CI 1.00-9.83). CONCLUSIONS: Prevalence of asymptomatic PAD in a relatively young HIV-infected cohort is similar to that observed in the uninfected middle-aged adult population. Overweight, obesity and advanced clinical stage of HIV infection (AIDS-defining conditions) were identified as independent risk factors for PAD.

Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers Withdrawal Is Associated with Higher Mortality in Hospitalized Patients with COVID-19.

Our main aim was to describe the effect on the severity of ACEI (angiotensin-converting enzyme inhibitor) and ARB (angiotensin II receptor blocker) during COVID-19 hospitalization. A retrospective, observational, multicenter study evaluating hospitalized patients with COVID-19 treated with ACEI/ARB. The primary endpoint was the incidence of the composite outcome of prognosis (IMV (invasive mechanical ventilation), NIMV (non-invasive mechanical ventilation), ICU admission (intensive care unit), and/or all-cause mortality). We evaluated both outcomes in patients whose treatment with ACEI/ARB was continued or withdrawn. Between February and June 2020, 11,205 patients were included, mean age 67 years (SD = 16.3) and 43.1% female; 2162 patients received ACEI/ARB treatment. ACEI/ARB treatment showed lower all-cause mortality (p < 0.0001). Hypertensive patients in the ACEI/ARB group had better results in IMV, ICU admission, and the composite outcome of prognosis (p < 0.0001 for all). No differences were found in the incidence of major adverse cardiovascular events. Patients previously treated with ACEI/ARB continuing treatment during hospitalization had a lower incidence of the composite outcome of prognosis than those whose treatment was withdrawn (RR 0.67, 95%CI 0.63-0.76). ARB was associated with better survival than ACEI (HR 0.77, 95%CI 0.62-0.96). ACEI/ARB treatment during COVID-19 hospitalization was associated with protection on mortality. The benefits were greater in hypertensive, those who continued treatment, and those taking ARB.

Paciente con alto riesgo cardiovascular y fibrilación auricular: papel del rivaroxabán / Patients with a high cardiovascular risk and atrial fibrillation: the role of rivaroxaban

Tradicionalmente el objetivo de la anticoagulación para el paciente con fibrilación auricular se centra principalmente en la prevención del ictus. Pero lo cierto es que estos pacientes tienen numerosas comorbilidades que también condicionan el pronóstico de manera muy importante y es necesario abordar. Esto también debería condicionar la elección del mejor tratamiento anticoagulante para el paciente en alto riesgo cardiovascular. En general, la eficacia y la seguridad de los 4 anticoagulantes orales de acción directa frente a warfarina son consistentes, independientemente de que el paciente tenga antecedentes de ictus/ accidente isquémico transitorio, diabetes mellitus, insuficiencia renal o infarto de miocardio. En el caso del rivaroxabán, varios estudios muestran que podría reducir el riesgo de infarto de miocardio y generar menos complicaciones renales que la warfarina. En un subestudio del ROCKET-AF, en pacientes con diabetes mellitus, el rivaroxabán redujo significativamente (20%) la mortalidad cardiovascular y estudios de práctica clínica muestran que el rivaroxabán no solo reduce significativamente el riesgo de eventos cardiovasculares mayores, sino también el riesgo de enfermedad arterial periférica. Como resultado de todo ello, el rivaroxabán podría considerarse como una opción preferente para la anticoagulación de los pacientes con fibrilación auricular no valvular y alto riesgo cardiovascular, por las ventajas adicionales que proporciona en esta población

Traditionally the primary aim of anticoagulation in patients with atrial fibrillation was the prevention of stroke. However, these patients actually have numerous comorbidities that also have a substantial impact on prognosis and that must be treated. These considerations should also play a role in selecting the best anticoagulant treatment for patients with a high cardiovascular risk. In general, direct oral anticoagulants have consistently been shown to have superior efficacy and safety to warfarin, irrespective of whether patients have a history of stroke, transient ischemic attack, diabetes, renal insufficiency or myocardial infarction. In particular, studies have shown that rivaroxaban is associated with a lower risk of myocardial infarction and fewer renal complications than warfarin. In a subgroup study of the ROCKET-AF trial, it was found that rivaroxaban significantly reduced cardiovascular mortality in patients with diabetes mellitus (by 20%). Moreover, studies carried out in routine clinical practice showed that the drug significantly reduces the risk of both major cardiovascular events and peripheral artery disease. As a result, rivaroxaban could be considered the preferred option for anticoagulation in patients with nonvalvular atrial fibrillation and a high cardiovascular risk, given the additional benefits it provides in this population

Enfermedad arterial periférica asintomática estimada mediante el índicetobillo-brazo en pacientes con infección por el VIH: prevalencia y factoresde riesgo asociados / Asymptomatic peripheral arterial disease detected by the ankle-brachial index in HIV-infected patients: prevalence and associated risk factors

Introducción: La infección por el virus de la inmunodeficiencia humana (VIH) se ha asociado a un mayor riesgo de aterosclerosis subclínica y de episodios cardiovasculares. La enfermedad arterial periférica (EAP)es un buen marcador de aterosclerosis sistémica y un importante predictor de morbilidad y mortalidad de origen cardiovascular. El objetivo de este estudio fue determinar la prevalencia de EAP asintomática y los factores de riesgo asociados en los pacientes infectados por el VIH. Métodos: Estudio transversal de los pacientes infectados por el VIH mayores de 20 años, sin síntomas de claudicación intermitente, atendidos de forma consecutiva en nuestra unidad entre noviembre de 2008 y diciembre de 2009. Se evaluó la presencia de EAP mediante la determinación del índice tobillo-brazo (ITB)en reposo. La EAP se definió como un ITB (..) (AU)
