RESUMEN
The diagnostic criteria, treatments at the time of admission, and drugs used in patients with acute coronary syndrome are well defined in countless guidelines. However, there is uncertainty about the measures to recommend during patient discharge planning. This document brings together the most recent evidence and the standardized and optimal treatment for patients at the time of discharge from hospitalization for an acute coronary syndrome, for comprehensive and safe care in the patient's transition between care from the acute event to the outpatient care, with the aim of optimizing the recovery of viable myocardium, guaranteeing the most appropriate secondary prevention, reducing the risk of a new coronary event and mortality, as well as the adequate reintegration of patients into daily life.
Los criterios diagnósticos, los tratamientos en el momento de la admisión y los fármacos utilizados en pacientes con síndrome coronario agudo están bien definidos en innumerables guías. Sin embargo, existe incertidumbre acerca de las medidas para recomendar durante la planificación del egreso de los pacientes. Este documento reúne las evidencias más recientes y el tratamiento estandarizado y óptimo para los pacientes al momento del egreso de una hospitalización por un síndrome coronario agudo, para un cuidado integral y seguro en la transición del paciente entre la atención del evento agudo y el cuidado ambulatorio, con el objetivo de optimizar la recuperación de miocardio viable, garantizar la prevención secundaria más adecuada, reducir el riesgo de un nuevo evento coronario y la mortalidad, así como la adecuada reinserción de los pacientes en la vida cotidiana.

Abstract Introduction: In Mexico, cardiac rehabilitation (CR) as an interdisciplinary intervention with therapeutic impact in patients with heart disease is growing. There is the need to know actual conditions of CR in our country. Objectives: The objective of this National Registry is to follow-up those existing and new CR units in Mexico through the comparison between the two previous registries, RENAPREC-2009 and RENAPREC II-2015 studies. This is a descriptive study focused on diverse CR activities such as assistance training, and certification of health professionals, barriers, reference, population attended, interdisciplinarity, permanence over time, growth prospects, regulations, post-pandemic condition, integrative characteristics, and scientific research. Results: Data were collected from 45 CR centers in the 32 states, 75.5% are private practice units, 67% are new, 33% were part of RENAPREC II-2015, and 17 have continued since 2009. With a better distribution of CR units along the territory, the median reference of candidates for CR programs is 9% with a significant reduction into tiempo of enrollment to Phase II admission (19 ± 11 days). Regarding to previous registries, the coverance of Phases I, II, and III is 71%, 100%, and 93%, respectively; and a coverance increases in evaluation, risk stratification, and prescription, more comprehensive attendance and prevention strategies. Conclusions: CR in Mexico has grown in the past 7 years. Even there is still low reference and heterogeneity in specific processes, there are strengths such as interdisciplinarity, scientific professionalization of specialists, national diversification, and an official society that are consolidated over time.

Introducción: En México, la Rehabilitación Cardíaca (RC) como intervención interdisciplinaria con impacto terapéutico en paciente con cardiopatía está en crecimiento. Existe la necesidad de conocer las condiciones actuales de la RC en nuestro país. Objetivo: El objetivo de este Registro es dar seguimiento comparativo de las unidades nuevas y existentes entre los registros anteriores, RENAPREC-2009 y RENAPREC II-2015. Se trata de un estudio descriptivo centrado en diversas actividades de la RC: formación asistencial y certificación de sus profesionales, barreras, referencia, población atendida, interdisciplinariedad, permanencia en el tiempo, perspectivas de crecimiento, normativa, condición pospandemia, características integradoras e investigación. Resultados: Se recolectaron datos de 45 centros en los 32 estados, 67% son nuevos 75.5% son de práctica privada, 33% fueron parte de RENAPREC II-2015 y 17 desde 2009. Con una mejor distribución de las unidades de RC a lo largo del territorio, la mediana de referencia de pacientes candidatos a RC es ahora del 9% con reducción significativa del tiempo de admisión a Fase II (19 ± 11 días). Respecto a registros anteriores las coberturas de las Fases I, II y III son del 71%, 100% y 93%, respectivamente; con un aumento de la cobertura en evaluación, estratificación de riesgo y prescripción, atención más integral y estrategias de prevención. Conclusiones: La RC en México ha crecido en los últimos 7 años. Si bien aún existe baja referencia y heterogeneidad en procesos específicos, existen fortalezas como la interdisciplinariedad, la profesionalización científica de los especialistas, la diversificación nacional y una sociedad oficial que se consolida en el tiempo.
RESUMEN
Background: In countries with emerging economies, the adequate and efficient management of resources is a priority, through strategies to reduce prolonged stay, increase the availability of beds, maximize profitability and reduce iatrogenic complications. Objective: The purpose of the study was to evaluate the effect of the "Follow up" strategy (FU) on the main indicators of the hospitalization process. Material and methods: A cross-sectional, comparative study was developed to evaluate the impact of the FU strategy on the indicators: hospital admissions and discharges, average days of hospital stay (DEH), percentage of hospital occupancy (OH), bed substitution interval (ISC), bed turnover rate (CRI) and prolonged hospital stay (EHP). Results: The FU was associated with a reduction in DEH [5.7 (5.5-6.1) vs. 6.5 days (6.1-6.9), p = 0.01]; ISC [0.6 (0.4-0.8) vs. 1.2 (0.8-1.3), p = 0.01] and EHP [23.6 (21.6-24.7) vs. 26.3% (24.4-28.7), p = 0.02] compared to the control group, with an increase in existence [1436 (1381-1472) vs. 1347 patient days (1280-1402), p = 0.02], respectively. There was no significant difference in the number of admissions, discharges or in the IRC. Conclusions: The FU reduces the average number of days of hospital stay, the rate of bed substitution and prolonged stay.
Introducción: en los países con economías emergentes es prioritaria la gestión adecuada y eficiente de los recursos hospitalarios. Las estrategias de gestión pueden reducir la estancia prolongada, aumentar la disponibilidad de camas, maximizar la rentabilidad y reducir las complicaciones iatrogénicas. Objetivo: el propósito del estudio fue evaluar el efecto de la estrategia de Follow up (FU) en los principales indicadores del proceso de hospitalización. Material y métodos: se desarrolló un estudio transversal, comparativo, para evaluar el impacto de la estrategia de FU en los indicadores: ingresos y egresos hospitalarios, promedio de días de estancia hospitalaria (DEH), porcentaje de ocupación hospitalaria (OH), intervalo de sustitución de camas (ISC), índice de rotación de camas (IRC) y estancia hospitalaria prolongada (EHP). Resultados: la estrategia de FU se asoció con una reducción de los DEH [5.7 (5.5-6.1) frente a 6.5 días (6.1-6.9), p = 0.01]; ISC [0.6 (0.4-0.8) frente a 1.2 (0.8-1.3), p = 0.01] y EHP [23.6 (21.6-24.7) frente a 26.3% (24.4-28.7), p = 0.02] respecto al grupo control, con incremento de la existencia [1436 (1381-1472) frente a 1347 días paciente (1280-1402), p = 0.02], respectivamente. No hubo diferencia significativa en el número de ingresos, egresos ni en el IRC. Conclusiones: la estrategia de FU disminuyó el promedio de días de estancia hospitalaria, el índice de sustitución de camas y la estancia prolongada.

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.

Patients suffering from cardiovascular disease require comprehensive medical attention that involves therapies and procedures necessary to reintegrate them optimally to their personal, family, work and social life. Interventions aimed at achieving these goals are included in cardiac rehabilitation programs. These programs are designed to limit the harmful physiological and psychological effects of heart disease, reduce the risk of sudden death or reinfarction, control cardiovascular symptoms, stabilize or reverse the atherosclerosis process and improve the psychosocial and vocational status of patients. These programs have existed in Mexico since the 1940's and have evolved over the years, adapting to the disease conditions present in our country, starting with therapies to treat patients with rheumatic heart disease until the application of physical exercise in patients with heart failure, complex congenital heart disease or pulmonary arterial hypertension. These activities are of a transdisciplinary nature and involve the integration of cardiologists, physiotherapists, psychologists, and nutritionists among others. Currently, these programs have spread throughout the Mexican Republic thanks to rehabilitation cardiologists graduating from the main health institutions in the country such as Health Institutes, Mexican Social Security Institute and Institute of Security and Social Services of State Workers. In this document, the origins of rehabilitation from the pre-Hispanic era to the present will be discussed, highlighting the contributions in teaching and research of the physicians who have practiced in this area in the aforementioned institutions.

OBJECTIVE: Exercise-induced premature ventricular complexes (EiPVCs) are often considered as benign arrhythmias, although they are associated with a high risk of all-cause death in the general healthy population. However, an intermediate pathophysiological process remains unclear, particularly in patients with known cardiovascular disease. The aim of this study was to find an association between EiPVCs, the occurrence of life-threatening ventricular arrhythmias (LACO), and all-cause mortality in patients with cardiovascular disease. METHODS: This was an observational study of a cohort of patients with coronary artery disease (CAD) or idiopathic cardiomyopathy (ICM). Stress testing was performed as a part of the routine cardiovascular evaluation. The occurrence of EiPVCs was evaluated during exercise testing (ET). At follow-up, long-term occurrence of LACO was evaluated. A bivariate and multivariate analysis was performed. RESULTS: Out of the total of 1442 patients analysed, 700 (49%) had EiPVCs. During 14 years of following-up after ET, 106 LACO outcomes were observed. Long-term all-cause mortality was 4% (n=61). A bivariate analysis showed that patients with EiPVCs had an increased risk for LACO (RR=2.81, 95% CI; 1.9-4.3, P<.001), and for mortality (RR=2.1, CI95% 1.2-3.4, P<.01). Occurrence of LACO was also associated with a higher mortality risk (RR=5.7, 95% CI; 3.4-9.4, P<.001). After a post hoc analysis, LACO remained as a highly predictive variable for mortality. CONCLUSION: Patients with EiPVCs have a high risk of LACO and all-cause mortality. The presence of LACO could be an intermediate stage between EiPVCs and mortality in subjects with cardiovascular disease.

Resumen Objetivo: La extrasistolia ventricular inducida por ejercicio (EVIE) suele considerarse una arritmia benigna, sin embargo, ha sido asociada a mayor mortalidad en población general. Hasta hoy no se ha encontrado el proceso fisiopatológico involucrado, particularmente en pacientes con enfermedad cardiovascular. El objetivo del estudio fue establecer una asociación entre EVIE con la ocurrencia de arritmias ventriculares potencialmente malignas (APM) y letalidad a largo plazo, en sujetos con enfermedad cardiovascular. Método: Estudiamos una cohorte de pacientes con enfermedad coronaria o miocardiopatía dilatada, que realizaron una prueba de ejercicio al inicio del estudio. Inicialmente evaluamos la ocurrencia de EVIE, APM y letalidad a largo plazo y posteriormente se realizó un estudio bivariable y multivariable. Resultados: Se incluyeron 1,442 pacientes de los cuales 700 presentaron EVIE (49%). Durante 14 an˜os de seguimiento, 106 sujetos presentaron APM y la mortalidad total fue de 61 casos (4%). El estudio bivariable mostró que aquellos pacientes con EVIE tuvieron un riesgo de presentar APM de 2.81 (IC95% de 1.9 a 4.3, p < 0.001) y de mortalidad de 2.1 (IC95% de 1.2 a 3.4, p < 0.01). Los individuos con APM tuvieron mayor riesgo de mortalidad (RR= 5.7, IC95% de 3.4 a 9.4, p < 0.001). Después de un análisis multivariable, la APM continuó siendo una variable altamente predictiva de mortalidad. Conclusión: Los pacientes con EVIE tienen un riesgo elevado de presentar APM y de mortalidad a largo plazo. Los resultados sugieren que las APM podrían representar un estado intermedio entre la presencia de EVIE y la mortalidad en pacientes con enfermedad cardiovascular.

Abstract: Objective: The aim of this paper is to compare the state of Cardiac Rehabilitation Programs (CRP) in 2009 with 2015. Focus is directed on health care, training of health-providers, research, and the barriers to their implementation. Methods: All authors of RENAPREC-2009, and other cardiac rehabilitation leaders in Mexico were requested to participate. These centres were distributed into two groups: RENAPREC-2009 centres that participated in 2015, and the new CRP units. Results: In 2009 there were 14 centres, two of which disappeared and another two did not respond. CRP-units increased by 71% (n = 24), and their geographic distribution shows a centripetal pattern. The coverage of CRP-units was 0.02 centres per 100,000 inhabitants. Only 4.4% of eligible patients were referred to CRP, with a rate of 10.4 patients/100,000 inhabitants in 2015. The ratio of Clinical Cardiologists to Cardiac Rehabilitation Specialists was 94:1, and the ratio of Intervention Specialists to cardiac rehabilitation experts was 16:1. Cardiac rehabilitation activities and costs varied widely. Patient dropout rate in phase II was 12%. Several barriers were identified: financial crisis (83%), lack of skilled personnel (67%), deficient equipment (46%), inadequate areas (42%), and a reduced number of operating centres (38%). Conclusions: CRPs in Mexico are still in the process of maturing. Mexican CRP-centres have several strengths, like the quality of the education of the professionals and the multidisciplinary programs. However, the lack of referral of patients and the heterogeneity of procedures are still their main weaknesses.
Resumen: Objetivo: El propósito de este trabajo es comparar el estado actual de los programas de rehabilitación cardiaca (PRC) en México con el RENAPREC-2009, dirigido a la asistencia, docencia, investigación y barreras. Métodos: Se convocó a participar a todos los autores de RENAPREC-2009 y a otros líderes en rehabilitación cardiaca de México. Los centros fueron distribuidos en 2 grupos: los que participaron en el 2015 y las nuevas unidades de PRC. Resultados: En 2009 había 14 centros operativos, de los cuales 2 cerraron y 2 no respondieron. En 2015 se registraron 24 centros en total, representando un aumento neto del 71%. La distribución geográfica fue centrípeta. La cobertura fue de 0.02 centros/100,000 habitantes y de solamente un 4.4% de los pacientes elegibles (10.4 pacientes/100,000 habitantes). La relación cardiólogo clínico-rehabilitador cardiaco es de 94:1 y la de intervencionista-rehabilitador cardiaco es de 16:1. Las actividades realizadas y los costos de los PRC varían de forma importante de centro a centro. En promedio, el 12% de los pacientes en fase ii abandonaron el programa. Las principales barreras para el desarrollo de PRC fueron: económicas (83%), falta de personal capacitado (67%), falta de equipo (46%), áreas inadecuadas (42%) y un insuficiente número de centros operativos (38%). Conclusiones: Los PRC en nuestro país continúan en crecimiento. Se observan fortalezas como el nivel de docencia y el enfoque multidisciplinario, así como deficiencias en la homogeneidad de las actividades y la falta de referencia de la población elegible.

Abstract: Introduction: Physical training programs (PTP) have shown several beneficial effects for patients with cardiovascular disease (CVD), particularly by increasing survival and quality of life. Physiological response during the effort and recovery phases of an exercise testing, is one of the strongest prognostic markers among patients with CVD. A reasonable mechanism that explains those training effects on survival is through the adaptations seen on heart rate recovery (HRR) and oxygen uptake kinetics at the post-exertional phase (RVO2). Objective: Compare the HRR and RVO2 values before and after a PTP in patients with CVD. Methods: We studied a cohort of patients included in a cardiac rehabilitation program, whom performed a cardiopulmonary exercise testing (CPX). Then, risk stratification and an individualized exercise training program were performed. The exercise training program included 20 sessions of aerobic exercise, 30 min a day, five times a week, at moderate intensity. Finally, a second CPX was performed. Results: A total of 215 patients were included. Peak oxygen uptake values rose 2.2 ± 5.2 ml/kg/min (p < 0.001), HRR increased 1.6 ± 10 bpm (p < 0.05) and RVO2 improved −21 ± 98 s (p < 0.001). A post-hoc analysis show that the percentage of maximum heart rate remained statistically associated with HRR increment. Furthermore, diabetes and sedentarism were strongly related to RVO2 improvement. No correlation between HRR and RVO2 was found (R2 = 0.002). Conclusion: Physical exercise was associated with a beneficial effect on HRR and RVO2. Nevertheless, both variables were statistically unrelated.
Resumen: Introducción: Los programas de entrenamiento físico han demostrado efectos benéficos en pacientes con enfermedad cardiovascular, particularmente debido al aumento de la supervivencia y calidad de vida. La respuesta fisiológica durante la prueba de esfuerzo cardiopulmonar tanto en las fases de ejercicio como de recuperación son de los principales marcadores pronósticos debido a la adaptación en la recuperación de la frecuencia cardiaca (RFC) y la cinética de recuperación de oxígeno en la fase de postesfuerzo (RVO2). Objetivo: Comparar los valores de RFC y RVO2 antes y después de un programa de entrenamiento físico. Métodos: Se estudió una cohorte de pacientes incluidos en un programa de rehabilitación cardiaca, que hayan realizado una prueba de esfuerzo cardiopulmonar. El programa de entrenamiento consistió en 20 sesiones de ejercicio aeróbico de 30 min diarios, 5 veces a la semana de intensidad moderada. Por último, se realizó una segunda prueba de esfuerzo cardiopulmonar. Resultados: Se incluyeron 215 pacientes. El consumo pico de oxígeno aumentó en 2.2 ± 5.2 ml/kg/min (p < 0.001), la RFC se incrementó 1.6 ± 10 lpm (p < 0.05) y mejoró la RVO2 −21 ± 98 seg (p < 0.001). En el análisis post-hoc se observó que el porcentaje de la frecuencia cardiaca máxima se mantuvo asociado con el incremento de la RFC. Por otra parte, la diabetes y el sedentarismo estuvieron fuertemente asociados con la mejora de la RVO2. No se observó correlación entre RFC y RVO2 (R2 = 0.002). Conclusiones: El ejercicio físico se asoció con un efecto benéfico sobre la RFC y la RVO2. Sin embargo, ambas variables no se relacionaron estadísticamente.
RESUMEN
OBJECTIVE: The aim of this paper is to compare the state of Cardiac Rehabilitation Programs (CRP) in 2009 with 2015. Focus is directed on health care, training of health-providers, research, and the barriers to their implementation. METHODS: All authors of RENAPREC-2009, and other cardiac rehabilitation leaders in Mexico were requested to participate. These centres were distributed into two groups: RENAPREC-2009 centres that participated in 2015, and the new CRP units. RESULTS: In 2009 there were 14 centres, two of which disappeared and another two did not respond. CRP-units increased by 71% (n=24), and their geographic distribution shows a centripetal pattern. The coverage of CRP-units was 0.02 centres per 100,000 inhabitants. Only 4.4% of eligible patients were referred to CRP, with a rate of 10.4 patients/100,000 inhabitants in 2015. The ratio of Clinical Cardiologists to Cardiac Rehabilitation Specialists was 94:1, and the ratio of Intervention Specialists to cardiac rehabilitation experts was 16:1. Cardiac rehabilitation activities and costs varied widely. Patient dropout rate in phase II was 12%. Several barriers were identified: financial crisis (83%), lack of skilled personnel (67%), deficient equipment (46%), inadequate areas (42%), and a reduced number of operating centres (38%). CONCLUSIONS: CRPs in Mexico are still in the process of maturing. Mexican CRP-centres have several strengths, like the quality of the education of the professionals and the multidisciplinary programs. However, the lack of referral of patients and the heterogeneity of procedures are still their main weaknesses.

RESUMEN
Heart failure is a health problem associated with disability and mortality. Physicians may stratify the risk of adult patients with heart failure using a cardiopulmonary exercise testing. Until now, in childhood this evaluation has been poorly used. The purpose of this study is to compare the peak oxygen uptake and minute ventilation/carbon dioxide production slope among children with heart failure versus children without heart disease (control). METHODS: Thirty-eight children with heart failure were compared with 194 children without heart disease. All of them performed cardiopulmonary exercise testing using a symptom-limited ramp protocol. Differences between groups were compared using Chi-squared test, Student's t test, or ANOVA. Any value of p < 0.05 was considered significant. RESULTS: Children with heart failure were older, taller, and with a higher prevalence of male gender. This group had also a lower peak oxygen uptake (27 ± 10 ml O2/kg/min) compared to the control group (37 ± 10 ml O2/kg/min); p < 0.001. The minute ventilation/carbon dioxide production was higher in the heart failure group (31 ± 4) than in controls (28 ± 6); p < 0.001. CONCLUSION: Children with heart failure showed lower peak oxygen uptake and higher minute ventilation/carbon dioxide production slope than the control group.
