Baseline characteristics of patients with heart failure with mildly reduced or preserved ejection fraction: The FINEARTS-HF trial.

AIMS: To describe the baseline characteristics of participants in the FINEARTS-HF trial, contextualized with prior trials including patients with heart failure (HF) with mildly reduced and preserved ejection fraction (HFmrEF/HFpEF). The FINEARTS-HF trial is comparing the effects of the non-steroidal mineralocorticoid receptor antagonist finerenone with placebo in reducing cardiovascular death and total worsening HF events in patients with HFmrEF/HFpEF. METHODS AND RESULTS: Patients with symptomatic HF, left ventricular ejection fraction (LVEF) ≥40%, estimated glomerular filtration rate ≥ 25 ml/min/1.73 m2, elevated natriuretic peptide levels and evidence of structural heart disease were enrolled and randomized to finerenone titrated to a maximum of 40 mg once daily or matching placebo. We validly randomized 6001 patients to finerenone or placebo (mean age 72 ± 10 years, 46% women). The majority were New York Heart Association functional class II (69%). The baseline mean LVEF was 53 ± 8% (range 34-84%); 36% of participants had a LVEF <50% and 64% had a LVEF ≥50%. The median N-terminal pro-B-type natriuretic peptide (NT-proBNP) was 1041 (interquartile range 449-1946) pg/ml. A total of 1219 (20%) patients were enrolled during or within 7 days of a worsening HF event, and 3247 (54%) patients were enrolled within 3 months of a worsening HF event. Compared with prior large-scale HFmrEF/HFpEF trials, FINEARTS-HF participants were more likely to have recent (within 6 months) HF hospitalization and greater symptoms and functional limitations. Further, concomitant medications included a larger percentage of sodium-glucose cotransporter 2 inhibitors and angiotensin receptor-neprilysin inhibitors than previous trials. CONCLUSIONS: FINEARTS-HF has enrolled a broad range of high-risk patients with HFmrEF and HFpEF. The trial will determine the safety and efficacy of finerenone in this population.

[Lifestyle modification and risk factor control in the prevention and treatment of atrial fibrillation]. / Modificaciones en el estilo de vida y control de los factores de riesgo en la prevención y el tratamiento de la fibrilación auricular.

Atrial fibrillation (AF) is the most prevalent arrhythmia and is related with significant morbidity, mortality and costs. In spite of relevant advances in the prevention of embolic events and rhythm control, little has been done to reduce its prevalence, progression and impact, since it increases with ageing as well as with common risk factors such as alcohol intake, tobacco use and stress as well as with arterial hypertension, diabetes mellitus, heart failure, sleep apnea, kidney failure, chronic pulmonary obstructive disease, ischemic heart disease and stroke, among other important comorbidities. Fortunately, new evidence suggests that lifestyle modifications and adequate risk factors and comorbidities control could be effective in primary and secondary AF prevention, especially in its paroxysmal presentations. This is why a multidisciplinary approach integrating lifestyle modifications, risk factors and comorbidities control, is necessary in conjunction with rhythm or rate control and anticoagulation. Unfortunately, that holistic approach strategy is not considered, is scarcely studied or is subtilized in general clinical practice. The present statement's objectives are to: 1) review the relationship between habits, risk factors and illnesses with AF, 2) review the individual and common physiopathology mechanisms of each one of those conditions that may lead to AF, 3) review the effect of control of habits, risk factors and co-morbidities on the control and impact of AF, and 4) supply guidelines and recommendations to start multidisciplinary and integrative AF treatment.

La fibrilación auricular (FA) es la arritmia más frecuente y se asocia con importante morbilidad, mortalidad y costos. A pesar de los grandes avances en la prevención de eventos embólicos y en el control del ritmo, poco se ha realizado para reducir su prevalencia, progresión e impacto, debido a que incrementa con la edad y con la presencia de múltiples factores de riesgo muy comunes en la población, como obesidad, sedentarismo, alcoholismo, tabaquismo y estrés, así como con hipertensión arterial sistémica, diabetes mellitus, insuficiencia cardiaca, apnea del sueño, enfermedad renal crónica, enfermedad pulmonar obstructiva crónica, cardiopatía isquémica y enfermedad vascular cerebral, entre otra comorbilidad importante. Afortunadamente, nuevas evidencias demuestran que las modificaciones en el estilo de vida y el control adecuado de los factores de riesgo y de la comorbilidad pueden ser efectivos en la prevención primaria y secundaria de la FA, en especial en sus formas paroxísticas; para ello, es necesario un manejo multidisciplinario que integre las modificaciones en el estilo de vida, el manejo de los factores de riesgo y el control de la comorbilidad en el tratamiento de la FA en conjunto con el control del ritmo o de la frecuencia y la anticoagulación. Por desgracia, en la práctica clínica estas estrategias a menudo no se tienen en cuenta, son infrautilizadas y poco estudiadas. Los objetivos del presente posicionamiento son: 1) revisar la relación de los factores de riesgo y la comorbilidad con la FA, 2) revisar los mecanismos fisiopatológicos de cada una de estas condiciones, 3) revisar el impacto del control de los factores de riesgo y de la comorbilidad en el control y en el impacto de la FA, y 4) proporcionar guías y recomendaciones para la puesta en práctica de programas de tratamiento multidisciplinario e integral en pacientes con FA.

A cross-sectional study on the prevalence of cardiovascular disease in elderly patients with long-term type 2 diabetes mellitus mainly attended in private clinics in Mexico. The CAPTURE study.

BACKGROUND: To estimate the contemporary prevalence of established cardiovascular disease (CVD) in adults with type 2 diabetes (T2D) in Mexico. METHODS: CAPTURE was a multinational, non-interventional, cross-sectional study across 13 countries from five continents. Standardized demographic and clinical data were collected from adults with T2D attending a single routine healthcare visit in primary or specialized care between December 2018 and September 2019. Data from Mexico are analyzed in this study. RESULTS: Of the 9,823 patients included in the CAPTURE study, 820 (8.3%) participants were from Mexico, mainly attended in private centers (29.3% in 6 specialized diabetes treatment centers and 70.7% in 26 primary care centers). The median age was 63.0 years, 52.6% were women, the duration of diabetes was 11.8 years and the average HbA1c 7.5%. The weighted prevalence [95% CI] of CVD and atherosclerotic CVD was 36.9% [34.1-39.6] and 29.5% [26.7-32.3], respectively. Additionally, the prevalence of coronary heart disease, heart failure, peripheral arterial disease and cerebrovascular disease was 23.1% [20.6-25-7], 8.4% [6.8-10.0], 5.0% [3.5-6.5] and 3.9% [2.6-5.2], respectively. Glucose lowering drugs were used in 88.5% of patients, being metformin the most commonly drug used (79.4%), followed by sulfonylureas (26.3%). SGLT-2 inhibitors and GLP1 receptor agonists were used in 15.5% and 3.9%, respectively. CONCLUSIONS: In Mexico, nearly four out of ten patients with T2D mainly attended in private centers have CVD, particularly atherosclerotic CVD. Most patients were not taking glucose lowering drugs with proven CV benefit.

Abstract Objective: To know the epidemiological behavior and associations of AF in Mexican population. Material and methods: 8,686 patients from 38 cardiologists participating in REMECAR were analyzed. They were divided by gender and age, the comorbidities studied were obesity, chronic kidney disease (CKD), high blood pressure (HBP), diabetes mellitus (DM), dyslipidemia, stroke, chronic obstructive pulmonary disease (COPD), hypothyroidism, heart failure (HF) and ischemic heart disease (IHD). Program used: IBM SPSS Statistic. Results: AF was diagnosed in 498 patients (5.7%), with higher prevalence in men (6.1% vs. 5.3%) and older age in women (74.3 ± 12.1 vs. 70.5 + -12.3 years, p<0.0001). In those under 60 years, AF was associated in women with HF, in men with CKD, DM, stroke, hypothyroidism and HF. In women older than 60 years, AF was associated with CKD, dyslipidemia, stroke, chronic COPD and HF, in men with CKD, stroke, COPD, hypothyroidism, HF and IHD. AF in women increase the probability 1.13 for obesity, 1.13 for HBP, 2.8 for CKD, 2.9 for COPD, 4.3 for stroke and 6.5 for HF, in men increase the probability 1.05 for HBP, 1.4 for DM, 2.1 for CKD, 2.4 for COPD, 3.0 for hypothyroidism, 4.7 for stroke and 6.0 for HF. Conclusions: AF is a very common arrhythmia, with a higher prevalence in patients attending the cardiology consultation, in men and with an older age of presentation in women. The older the age, the higher the prevalence of AF and comorbidities, HF is the most frequent condition associated with AF.

Dapagliflozin in Heart Failure with Mildly Reduced or Preserved Ejection Fraction.

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce the risk of hospitalization for heart failure and cardiovascular death among patients with chronic heart failure and a left ventricular ejection fraction of 40% or less. Whether SGLT2 inhibitors are effective in patients with a higher left ventricular ejection fraction remains less certain. METHODS: We randomly assigned 6263 patients with heart failure and a left ventricular ejection fraction of more than 40% to receive dapagliflozin (at a dose of 10 mg once daily) or matching placebo, in addition to usual therapy. The primary outcome was a composite of worsening heart failure (which was defined as either an unplanned hospitalization for heart failure or an urgent visit for heart failure) or cardiovascular death, as assessed in a time-to-event analysis. RESULTS: Over a median of 2.3 years, the primary outcome occurred in 512 of 3131 patients (16.4%) in the dapagliflozin group and in 610 of 3132 patients (19.5%) in the placebo group (hazard ratio, 0.82; 95% confidence interval [CI], 0.73 to 0.92; P<0.001). Worsening heart failure occurred in 368 patients (11.8%) in the dapagliflozin group and in 455 patients (14.5%) in the placebo group (hazard ratio, 0.79; 95% CI, 0.69 to 0.91); cardiovascular death occurred in 231 patients (7.4%) and 261 patients (8.3%), respectively (hazard ratio, 0.88; 95% CI, 0.74 to 1.05). Total events and symptom burden were lower in the dapagliflozin group than in the placebo group. Results were similar among patients with a left ventricular ejection fraction of 60% or more and those with a left ventricular ejection fraction of less than 60%, and results were similar in prespecified subgroups, including patients with or without diabetes. The incidence of adverse events was similar in the two groups. CONCLUSIONS: Dapagliflozin reduced the combined risk of worsening heart failure or cardiovascular death among patients with heart failure and a mildly reduced or preserved ejection fraction.

Dapagliflozin for heart failure according to body mass index: the DELIVER trial.

AIMS: Obesity is common and associated with unique phenotypic features in heart failure with preserved ejection fraction (HFpEF). Therefore, understanding the efficacy and safety of new therapies in HFpEF patients with obesity is important. The effects of dapagliflozin were examined according to body mass index (BMI) among patients in the Dapagliflozin Evaluation to Improve the LIVEs of Patients With PReserved Ejection Fraction Heart Failure trial. METHODS AND RESULTS: Body mass index was analysed by World Health Organization (WHO) categories and as a continuous variable using restricted cubic splines. Body mass index ranged from 15.2 to 50 kg/m2 with a mean value of 29.8 (standard deviation ± 6.1) kg/m2. The proportions, by WHO category, were: normal weight 1343 (21.5%); overweight 2073 (33.1%); Class I obesity 1574 (25.2%); Class II obesity 798 (12.8%); and Class III obesity 415 (6.6%). Compared with placebo, dapagliflozin reduced the risk of the primary outcome to a similar extent across these categories: hazard ratio (95% confidence interval): 0.89 (0.69-1.15), 0.87 (0.70-1.08), 0.74 (0.58-0.93), 0.78 (0.57-1.08), and 0.72 (0.47-1.08), respectively (P-interaction = 0.82). The placebo-corrected change in Kansas City Cardiomyopathy Questionnaire total symptom score with dapagliflozin at 8 months was: 0.9 (-1.1, 2.8), 2.5 (0.8, 4.1), 1.9 (-0.1, 3.8), 2.7 (-0.5, 5.8), and 8.6 (4.0, 13.2) points, respectively (P-interaction = 0.03). The placebo-corrected change in weight at 12 months was: -0.88 (-1.28, -0.47), -0.65 (-1.04, -0.26), -1.42 (-1.89, -0.94), -1.17 (-1.94, -0.40), and -2.50 (-4.4, -0.64) kg (P-interaction = 0.002). CONCLUSIONS: Obesity is common in patients with HFpEF and is associated with higher rates of heart failure hospitalization and worse health status. Treatment with dapagliflozin improves cardiovascular outcomes across the spectrum of BMI, leads to greater symptom improvement in patients with obesity, compared with those without, and has the additional benefit of causing modest weight loss.

Baseline Characteristics of Patients With HF With Mildly Reduced and Preserved Ejection Fraction: DELIVER Trial.

OBJECTIVES: This report describes the baseline clinical profiles and management of DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) trial participants and how these compare with those in other contemporary heart failure with preserved ejection fraction trials. BACKGROUND: The DELIVER trial was designed to evaluate the effects of the sodium-glucose cotransporter-2 inhibitor dapagliflozin on cardiovascular death, heart failure (HF) hospitalization, or urgent HF visits in patients with HF with mildly reduced and preserved left ventricular ejection fraction (LVEF). METHODS: Adults with symptomatic HF and LVEF >40%, with or without type 2 diabetes mellitus, elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, and evidence of structural heart disease were randomized to dapagliflozin 10 mg once daily or matching placebo. RESULTS: A total of 6,263 patients were randomized (mean age: 72 ± 10 years; 44% women; 45% type 2 diabetes mellitus; 45% with body mass index ≥30 kg/m2; and 57% with history of atrial fibrillation or flutter). Most participants had New York Heart Association functional class II symptoms (75%). Baseline mean LVEF was 54.2 ± 8.8% and median NT-proBNP of 1,399 pg/mL (IQR: 962 to 2,210 pg/mL) for patients in atrial fibrillation/flutter compared with 716 pg/mL (IQR: 469 to 1,281 pg/mL) in those who were not. Patients in both hospitalized and ambulatory settings were enrolled, including 10% enrolled in-hospital or within 30 days of a hospitalization for HF. Eighteen percent of participants had HF with improved LVEF. CONCLUSIONS: DELIVER is the largest and broadest clinical trial of this population to date and enrolled high-risk, well-treated patients with HF with mildly reduced and preserved LVEF. (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure [NCT03619213]).

Guía de práctica clínica mexicana para el diagnóstico y tratamiento de las dislipidemias y enfermedad cardiovascular aterosclerótica.

ANTECEDENTES: Las enfermedades cardiovasculares son la principal causa mundial de mortalidad y México no es la excepción. Los datos epidemiológicos obtenidos en 1990 mostraron que los padecimientos cardiovasculares representaron el 19.8% de todas las causas de muerte en nuestro país; esta cifra se incrementó de manera significativa a un 25.5% para 2015. Diversas encuestas nacionales sugieren que más del 60% de la población adulta tiene al menos un factor de riesgo para padecer enfermedades cardiovasculares (obesidad o sobrepeso, hipertensión, tabaquismo, diabetes, dislipidemias). Por otro lado, datos de la Organización Panamericana de la Salud han relacionado el proceso de aterosclerosis como la primer causa de muerte prematura, reduciendo la expectativa de vida de manera sensible, lo que tiene una enorme repercusión social. OBJETIVO: Este documento constituye la guía de práctica clínica (GPC) elaborada por iniciativa de la Sociedad Mexicana de Cardiología en colaboración con la Sociedad Mexicana de Nutrición y Endocrinología, A.C., Asociación Nacional de Cardiólogos de México, A.C., Asociación Mexicana para la Prevención de la Aterosclerosis y sus Complicaciones, A.C., Comité Normativo Nacional de Medicina General, A.C., Colegio Nacional de Medicina Geriátrica, A.C., Colegio de Medicina Interna de México, A.C., Sociedad Mexicana de Angiología y Cirugía Vascular y Endovenosa, A.C., Instituto Mexicano de Investigaciones Nefrológicas, A.C. y la Academia Mexicana de Neurología, A.C.; con el apoyo metodológico de la Agencia Iberoamericana de Desarrollo y Evaluación de Tecnologías en Salud, con la finalidad de establecer recomendaciones basadas en la mejor evidencia disponible y consensuadas por un grupo interdisciplinario de expertos. El objetivo de este documento es el de brindar recomendaciones basadas en evidencia para ayudar a los tomadores de decisión en el diagnóstico y tratamiento de las dislipidemias en nuestro país. MATERIAL Y MÉTODOS: Este documento cumple con estándares internacionales de calidad, como los descritos por el Instituto de Medicina de EE.UU., el Instituto de Excelencia Clínica de Gran Bretaña, la Red Colegiada para el Desarrollo de Guías de Escocia y la Red Internacional de Guías de Práctica Clínica. Se integró un grupo multidisciplinario de expertos clínicos y metodólogos con experiencia en revisiones sistemáticas de la literatura y el desarrollo de guías de práctica clínica. Se consensuó un documento de alcances, se establecieron las preguntas clínicas relevantes, se identificó de manera exhaustiva la mejor evidencia disponible evaluada críticamente en revisiones sistemáticas de la literatura y se desarrollaron las recomendaciones clínicas. Se utilizó la metodología de Panel Delphi modificado para lograr un nivel de consenso adecuado en cada una de las recomendaciones contenidas en esta GPC. RESULTADOS: Se consensuaron 23 preguntas clínicas que dieron origen a sus respectivas recomendaciones clínicas. CONCLUSIONES: Esperamos que este documento contribuya a la mejor toma de decisiones clínicas y se convierta en un punto de referencia para los clínicos y pacientes en el manejo de las dislipidemias y esto contribuya a disminuir la morbilidad y mortalidad derivada de los eventos cardiovasculares ateroscleróticos en nuestro país. BACKGROUND: Cardiovascular diseases are the leading cause of mortality worldwide and Mexico is no exception. The epidemiological data obtained in 1990 showed that cardiovascular diseases represented 19.8% of all causes of death in our country. This figure increased significantly to 25.5% for 2015. Some national surveys suggest that more than 60% of the adult population has at least one risk factor for cardiovascular disease (obesity or overweight, hypertension, smoking, diabetes, dyslipidemias). On the other hand, data from the Pan American Health Organization have linked the process of atherosclerosis as the first cause of premature death, significantly reducing life expectancy, which has enormous social repercussions. OBJECTIVE: This document constitutes the Clinical Practice Guide (CPG) prepared at the initiative of the Mexican Society of Cardiology in collaboration with the Mexican Society of Nutrition and Endocrinology, AC, National Association of Cardiologists of Mexico, AC, Mexican Association for the Prevention of Atherosclerosis and its Complications, AC, National Normative Committee of General Medicine, AC, National College of Geriatric Medicine, AC, College of Internal Medicine of Mexico, AC, Mexican Society of Angiology and Vascular and Endovenous Surgery, AC, Mexican Institute of Research Nephrological, AC and the Mexican Academy of Neurology, A.C.; with the methodological support of the Ibero-American Agency for the Development and Evaluation of Health Technologies, in order to establish recommendations based on the best available evidence and agreed upon by an interdisciplinary group of experts. The objective of this document is to provide evidence-based recommendations to help decision makers in the diagnosis and treatment of dyslipidemias in our country. MATERIAL AND METHODS: This document complies with international quality standards, such as those described by the Institute of Medicine of the USA, the Institute of Clinical Excellence of Great Britain, the Scottish Intercollegiate Guideline Network and the Guidelines International Network. A multidisciplinary group of clinical experts and methodologists with experience in systematic reviews of the literature and the development of clinical practice guidelines was formed. A scope document was agreed upon, relevant clinical questions were established, the best available evidence critically evaluated in systematic literature reviews was exhaustively identified, and clinical recommendations were developed. The modified Delphi Panel methodology was used to achieve an adequate level of consensus in each of the recommendations contained in this CPG. RESULTS: 23 clinical questions were agreed upon which gave rise to their respective clinical recommendations. CONCLUSIONS: We consider that this document contributes to better clinical decision-making and becomes a point of reference for clinicians and patients in the management of dyslipidemias and this contributes to reducing the morbidity and mortality derived from atherosclerotic cardiovascular events in our country.

Documento de consenso sobre el uso de iSGLT2 en pacientes con enfermedad renal crónica y diabetes.

La enfermedad renal crónica (ERC) del paciente diabético es frecuentemente una consecuencia directa de la diabetes mellitus (DM) de larga evolución y se la conoce como nefropatía diabética. En México cerca del 50% de los pacientes en terapia sustitutiva de la función renal tienen ERC por DM, y este porcentaje podría aumentar en los próximos años. Nuevas opciones terapéuticas, combinadas con cambios en el estilo de vida, han mejorado el control de la glucemia y pueden contribuir sustancialmente a retrasar la aparición o la progresión a estadios avanzados de la ERC. Las sociedades científicas internacionales han elaborado guías clínicas para el diagnóstico y manejo de la nefropatía diabética, sin embargo, en algunos puntos estas recomendaciones no se adaptan a la realidad mexicana. Se presentan las conclusiones de un consenso realizado por especialistas mexicanos sobre diabetes y ERC, con especial énfasis en el uso de los inhibidores del cotransportador de sodio-glucosa.Chronic kidney disease (CKD) in the diabetic patient is mainly a consequence of long-term diabetes mellitus itself. In Mexico approximately 50% of patients on dialysis are diabetics and this will could increase in the coming years. New therapeutic options available, combined with lifestyle changes, have improved glycemic control and may contribute to delay the onset as well as the progression of CKD. International scientific societies have developed clinical guidelines for the diagnosis and management of CKD in diabetics, although in some points, these recommendations are not adapted to the Mexican reality. We hereby present the conclusions of the consensus reached by Mexican specialists on diabetic nephropathy.

Atrial fibrillation in Mexican population: Differences in presentation, comorbidities and risk factors between men and women / Fibrilación auricular en población mexicana: Diferencias en presentación, comorbilidades y factores de riesgo entre hombres y mujeres

OBJECTIVE: To know the epidemiological behavior and associations of AF in Mexican population. MATERIAL AND METHODS: 8,686 patients from 38 cardiologists participating in REMECAR were analyzed. They were divided by gender and age, the comorbidities studied were obesity, chronic kidney disease (CKD), high blood pressure (HBP), diabetes mellitus (DM), dyslipidemia,stroke, chronic obstructive pulmonary disease (COPD), hypothyroidism, heart failure (HF) and ischemicheart disease (IHD). Program used: IBM SPSS Statistic. RESULTS: AF was diagnosed in 498 patients (5.7%), with higher prevalence in men (6.1% vs. 5.3%) and older age in women (74.3 ± 12.1 vs. 70.5 + -12.3 years, p<0.0001). In those under 60 years, AF was associated in women with HF, in men with CKD, DM, stroke, hypothyroidism and HF. In women older than 60 years, AF was associated with CKD, dyslipidemia, stroke, chronic COPD and HF, in men with CKD, stroke, COPD, hypothyroidism, HF and IHD. AF in women increase the probability 1.13 for obesity, 1.13 for HBP, 2.8 for CKD, 2.9 for COPD, 4.3 for stroke and 6.5 for HF, in men increase the probability 1.05 for HBP, 1.4 for DM, 2.1 for CKD, 2.4 for COPD, 3.0 for hypothyroidism, 4.7 for stroke and 6.0 for HF. CONCLUSIONS: AF is a very common arrhythmia, with a higher prevalence in patients attending the cardiology consultation, in men and with an older age of presentation in women. The older the age, the higher the prevalence of AF and comorbidities, HF is the most frequent condition associated with AF.

Risk stratification and lipid evaluation in mexican patients, evidence of lipid and cardiovascular analysis in REMECAR. The mexican registry of cardiovascular diseases (REMECAR group).

Background and aims: Dyslipidaemia is a significant risk factor for cardiovascular disease in the Mexican population. This analysis aimed to describe the baseline LDL-c levels of patients presenting to cardiovascular clinics and evaluate the proportion who achieved their risk-based LDL-c goals as recommended by 2021 ESC prevention guidelines. Methods: The REMECAR registry is an observational study of patients attending a specialized cardiovascular clinic for their first visit. The cardiovascular risk was retrospectively determined using the 2021 ESC guideline stratification and the SCORE2 and SCORE-OP. Results: A total of 5443 patients were included in the analysis. Within this population, 55.96% presented as very high, 39.98% as high and 4.06% as moderate to low risk. 63% of the participants were not on any lipid-lowering treatment at entry, while 12.4% were receiving high-intensity statin therapy. Patients presenting with established atherosclerotic cardiovascular disease had a mean LDL-c of 90.9 ± 40.7 mg/dL. Of these, 14.1% were achieving LDL-c levels of 70-55 mg/dL and 19.3% were achieving LDL-c levels <55 mg/dL. In diabetic patients at very high risk, only 25.7% achieved their LDL-c goal. Finally, in patients without another risk factor and very high-risk evaluated by SCORE2 & SCORE-OP, only 14% of patients achieved their LDL-c goals. Conclusions: An important number of patients were not receiving any lipid-lowering therapy. Furthermore, in those who were, a significant portion did not achieve LDL-c recommended thresholds. Our results underline the urgent need to improve the prescription and optimization of lipid-lowering therapy as the current management appears to be insufficient for achieving optimal recommended goals. Identifying key barriers in lipid management is fundamental to establishing better strategies and health system policies to reduce cardiovascular risk.

Documento de consenso sobre el uso de iSGLT2 en pacientes con enfermedad renal crónica y diabetes / Consesus document in the use of SGLT inhibitors in patients with diabetes and chronic kidney disease

Resumen La enfermedad renal crónica (ERC) del paciente diabético es frecuentemente una consecuencia directa de la diabetes mellitus (DM) de larga evolución y se la conoce como nefropatía diabética. En México cerca del 50% de los pacientes en terapia sustitutiva de la función renal tienen ERC por DM, y este porcentaje podría aumentar en los próximos años. Nuevas opciones terapéuticas, combinadas con cambios en el estilo de vida, han mejorado el control de la glucemia y pueden contribuir sustancialmente a retrasar la aparición o la progresión a estadios avanzados de la ERC. Las sociedades científicas internacionales han elaborado guías clínicas para el diagnóstico y manejo de la nefropatía diabética, sin embargo, en algunos puntos estas recomendaciones no se adaptan a la realidad mexicana. Se presentan las conclusiones de un consenso realizado por especialistas mexicanos sobre diabetes y ERC, con especial énfasis en el uso de los inhibidores del cotransportador de sodio-glucosa.

Abstract Chronic kidney disease (CKD) in the diabetic patient is mainly a consequence of long-term diabetes mellitus itself. In Mexico approximately 50% of patients on dialysis are diabetics and this will could increase in the coming years. New therapeutic options available, combined with lifestyle changes, have improved glycemic control and may contribute to delay the onset as well as the progression of CKD. International scientific societies have developed clinical guidelines for the diagnosis and management of CKD in diabetics, although in some points, these recommendations are not adapted to the Mexican reality. We hereby present the conclusions of the consensus reached by Mexican specialists on diabetic nephropathy.

Guía de práctica clínica mexicana para el diagnóstico y tratamiento de las dislipidemias y enfermedad cardiovascular aterosclerótica / Mexican clinical practice guideline for the diagnosis and treatment of dyslipidemias and atherosclerotic cardiovascular disease

resumen está disponible en el texto completo

Abstract Background: Cardiovascular diseases are the leading cause of mortality worldwide and Mexico is no exception. The epidemiological data obtained in 1990 showed that cardiovascular diseases represented 19.8% of all causes of death in our country. This figure increased significantly to 25.5% for 2015. Some national surveys suggest that more than 60% of the adult population has at least one risk factor for cardiovascular disease (obesity or overweight, hypertension, smoking, diabetes, dyslipidemias). On the other hand, data from the Pan American Health Organization have linked the process of atherosclerosis as the first cause of premature death, significantly reducing life expectancy, which has enormous social repercussions. Objective: This document constitutes the Clinical Practice Guide (CPG) prepared at the initiative of the Mexican Society of Cardiology in collaboration with the Mexican Society of Nutrition and Endocrinology, AC, National Association of Cardiologists of Mexico, AC, Mexican Association for the Prevention of Atherosclerosis and its Complications, AC, National Normative Committee of General Medicine, AC, National College of Geriatric Medicine, AC, College of Internal Medicine of Mexico, AC, Mexican Society of Angiology and Vascular and Endovenous Surgery, AC, Mexican Institute of Research Nephrological, AC and the Mexican Academy of Neurology, A.C.; with the methodological support of the Ibero-American Agency for the Development and Evaluation of Health Technologies, in order to establish recommendations based on the best available evidence and agreed upon by an interdisciplinary group of experts. The objective of this document is to provide evidence-based recommendations to help decision makers in the diagnosis and treatment of dyslipidemias in our country. Material and methods: This document complies with international quality standards, such as those described by the Institute of Medicine of the USA, the Institute of Clinical Excellence of Great Britain, the Scottish Intercollegiate Guideline Network and the Guidelines International Network. A multidisciplinary group of clinical experts and methodologists with experience in systematic reviews of the literature and the development of clinical practice guidelines was formed. A scope document was agreed upon, relevant clinical questions were established, the best available evidence critically evaluated in systematic literature reviews was exhaustively identified, and clinical recommendations were developed. The modified Delphi Panel methodology was used to achieve an adequate level of consensus in each of the recommendations contained in this CPG. Results: 23 clinical questions were agreed upon which gave rise to their respective clinical recommendations. Conclusions: We consider that this document contributes to better clinical decision-making and becomes a point of reference for clinicians and patients in the management of dyslipidemias and this contributes to reducing the morbidity and mortality derived from atherosclerotic cardiovascular events in our country.

STEMI telemedicine for 100 million lives.

BACKGROUND: Developing countries struggle to diagnose and treat ST-segment elevation myocardial infarction (STEMI) patients in a timely manner, and subsequent outcomes are suboptimal. METHODS: The Latin America Telemedicine Network (LATIN) functioned between 2013 to present in four countries-Brazil, Colombia, Mexico, and Argentina. A Hub and Spoke platform was developed to expand access to >100 million population for STEMI care. Patients were triaged at spokes that included small clinics and primary health care centers in remote South American locations. Three telemedicine command sites provided immediate 24/7 electrocardiogram diagnosis and teleconsultation of the STEMI process at 355 centers in four countries. RESULTS: LATIN Spokes (n = 313) screened up to 30,000 patients per month, and a total of 780,234 patients over the study period. Telemedicine experts diagnosed 8395 (1·1%) with STEMI, of which a total of 3872 (46·1%) were urgently treated at 47 Hubs. A total of 3015 patients (78%) were reperfused with percutaneous coronary intervention. Time-to-telemedicine diagnosis averaged 3·5 min. Average door-to-balloon time improved from 120 to 48 min during the study period and overall STEMI mortality was 5·2%. INTERPRETATION: Telemedicine transcends boundaries and enables access to millions of patients for STEMI care. With this initiative, LATIN has created a template for reducing disparities in STEMI management between developed and developing countries.

Return to exercise after COVID-19. Statement of the Mexican Society of Cardiology / Retorno al ejercicio después de COVID-19. Posicionamiento de la Sociedad Mexicana de Cardiología

The coronavirus disease 2019 (COVID-19) was declared a pandemic on March 11, 2020; one consequence has been the increase in sedentary lifestyle and reduction of sports activity. Exercise benefits the immune defense system especially in older adults; it is recommended to keep a distance of 1.5 meters between people, and if walking or jogging is carried out, the space must be up to 5 and 10 meters respectively. The reported cases are mostly mild up to 80% and can be critical in up to 4.7%; the risk factors are well known, hypertension, diabetes and previous heart disease. Severe or critical cases present as symptoms of acute respiratory distress syndrome, and in the case of cardiovascular disease, they mainly occur as myopericarditis, acute coronary syndromes, cardiogenic shock, thrombotic events, among others. Returning to exercise after recovery from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is always recommended, however it will depend on the clinical picture what measures should be taken prior to its onset, and it is in moderate cases and especially in the severe ones where the evaluation and prescription prior to returning to exercise or sport should be guided by medical personnel experts in cardiopulmonary rehabilitation, especially in athletes.

La enfermedad por coronavirus 2019 (COVID-19) fue declarada pandemia el 11 de marzo de 2020; una consecuencia ha sido el incremento en el sedentarismo y la reducción de la actividad deportiva. El ejercicio beneficia el sistema inmunitario de defensa, especialmente en adultos mayores. Se recomienda guardar distancia de 1.5 metros entre personas, y si se realiza caminata o trote, el espacio debe ser de hasta 5 y 10 metros respectivamente. Los casos reportados son en su mayoría leves hasta en un 80%, y pueden ser críticos hasta en 4.7%; los factores de riesgo son bien conocidos: hipertensión, diabetes y enfermedad cardiaca previa. Los casos graves o críticos se presentan como cuadros de síndrome de distrés respiratorio agudo y ante afección cardiovascular cursan principalmente como miopericarditis, síndromes coronarios agudos, choque cardiogénico y eventos trombóticos, entre otros. El ejercicio después de la recuperación de infección por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2) siempre está recomendado, sin embargo, dependerá del cuadro clínico qué medidas se deben tomar previo a su inicio, y es en casos moderados y especialmente en los graves donde la evaluación y prescripción previa al retorno al ejercicio o deporte debe ser guiada por personal médico experto en rehabilitación cardiopulmonar, en especial en deportistas.

Anticoagulation Therapy by Age and Embolic Risk for Nonvalvular Atrial Fibrillation in Mexico, an Upper-Middle-Income Country: The CARMEN-AF Registry.

Background: Documenting the patterns of oral anticoagulation therapy (OAT) is essential to prevent thromboembolic complications of nonvalvular atrial fibrillation (NVAF). Objective: To report the patterns of OAT according to age and thromboembolic risk in patients included in CARMEN-AF, a nationwide registry of NVAF in Mexico, an upper middle-income country. Material and methods: There were 1,423 consecutive patients ≥18 years old and with at least one thromboembolic risk factor enrolled in the CARMEN-AF Registry at their regular clinical visit during a three-year period. They were analyzed according to 1) age, 2) AF type, and 3) CHA2DS2-VASc score. Results: Overall, 16.4% of patients did not receive antithrombotic treatment, 19.4% received antiplatelet drugs (APD), 29.2% vitamin K antagonists (VKA), and 34.6% direct oral anticoagulants (DOAC). With increasing age, the proportion of subjects treated with VKA decreased significantly from 36.2% in subjects <65 years to 22.5% in those ≥75 years old (P <0.0001). Concomitantly, an increase in both APD and no antithrombotic treatment was observed with increasing age. DOAC were prescribed equally among all age groups (34.2% in <65, 36.0% in 65-74, and 33.9% in ≥75). According to the type of AF, VKA use was more common in patients with permanent AF (32.7%). A lower use of DOAC was observed in high thromboembolic risk subjects (33.6% in CHA2DS2-VASc ≥2) compared with the moderate risk group (41% in CHA2DS2-VASc = 1). Conclusions: VKA use for NVAF in Mexico decreased in relation to increasing age. The proportion of DOAC therapy was the same in all age groups. Nevertheless, elderly patients with high thromboembolic risk received a suboptimal thromboprophylaxis. These data could help to improve gaps in the implementation of global guidelines. Clinical trial registration: http://www.clinicaltrials.gov. Unique identifier: NCT02334852. Highlights: CARMEN-AF is a nationwide multi-centric registry seeking to bridge the data gap on anticoagulation therapy for NVAF in Mexico.Elderly patients are more prone to receive suboptimal OAT for NVAF.DOAC were less frequently used in high thromboembolic risk patients (CHA2DS2-VASc ≥2).
