[Third National Registry of Cardiac Rehabilitation Programs in Mexico (RENAPREC III-2022)]. / Tercer Registro Nacional de Programas de Rehabilitación Cardiaca en México (RENAPREC III-2022).

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.

Cardiovascular evaluation using exercise testing performed with face masks during the COVID-19 pandemic.

OBJECTIVE: COVID-19 pandemic is associated with high incidence and fatality, however, non-communicable diseases remain a global public health problem with even greater morbidity and mortality. At present, there is a lag in diagnosis and treatment of patients with heart disease, particularly the performance of exercise testing (ET), due to the fear of aerosol generation and viral dissemination. Although some centers carry out the tests with the use of masks, the information is still superficial and preliminary. The objective of the study was to describe the ergometric performance observed when performing exercise tests during the COVID-19 (PANDEMIC-G) pandemic and to highlight the differences with those results carried out in another time, when there was no COVID-19 (NO PANDEMIC). METHOD: A cross-sectional study was carried out. PANDEMIC-G patients underwent ET between March 2020 and December 2020, once a biological triage was done and all of them wore N95 masks. They were compared to NO PANDEMIC patients that performed an ET between March 2019 and December 2019. Demographic and ergometric variables were presented and analyzed according to their type. All p < 0.05 were considered stochastically significant. RESULTS: A total of 361 ET were studied: 209 (58%) belonged to NO PANDEMIC and 152 (42%) to PANDEMIC-G. The number of ET stopped by dyspnea was greater in PANDEMIC-G (117) than in NO PANDEMIC (8). Exercise tolerance did not show significant changes. Systolic blood pressure, double product, and myocardial oxygen utilization were higher in PANDEMIC-G ET (p < 0.01). CONCLUSIONS: In the COVID-era, fewer stress tests were performed, which were suspended more frequently due to dyspnea. Higher values of systolic blood pressure and myocardial oxygen utilization were observed in PANDEMIC-G as well.

OBJETIVO: La pandemia de COVID-19 se asocia con una alta incidencia y letalidad; sin embargo, las enfermedades no transmisibles siguen siendo un problema de salud pública mundial con una morbilidad y mortalidad aún mayores. Actualmente, existe un retraso en el diagnóstico y tratamiento de los pacientes con enfermedades cardíacas, particularmente en la realización de la prueba de esfuerzo (PE), debido al temor a la generación de aerosoles y la diseminación viral. Aunque algunos centros realizan las pruebas con el uso de tapabocas, la información aún es superficial y preliminar. El objetivo del estudio fue describir el desempeño ergométrico observado al realizar pruebas de ejercicio durante la pandemia COVID-19 (PANDEMIC-G) y remarcar las diferencias con las pruebas realizadas antes de ella (NO PANDEMIC). MÉTODO: Se realizó un estudio transversal. Los pacientes con PANDEMIC-G se sometieron a PE entre marzo y diciembre de 2020, una vez que se realizó un triaje biológico y todos usaron tapabocas N95. Fueron comparados con pacientes NO PANDEMIC, que realizaron una PE entre marzo y diciembre de 2019. Las variables se presentaron y analizaron según su tipo. Todos los valores de p inferiores a 0.05 se consideraron estocásticamente significativos. RESULTADOS: Se estudiaron un total de 361 PE, donde 209 (58%) pertenecían a NO PANDEMIC y 152 (42%) a PANDEMIC-G. El número de PE detenidas por disnea fue mayor en PANDEMIC-G (n = 117) que en NO PANDEMIC (n = 8). La tolerancia al ejercicio no mostró cambios significativos. La presión arterial sistólica, el producto doble y la utilización de oxígeno del miocardio fueron mayores en las PE en el PANDEMIC-G (p < 0.01). CONCLUSIONES: En la era COVID se realizaron menos pruebas de esfuerzo, que se suspendieron con mayor frecuencia por disnea. También se observaron valores más altos de presión arterial sistólica y utilización de oxígeno del miocardio en PANDEMIC-G.

[Effect of a physical training program on the occurrence of exercise-induced arrhythmias in patients with heart disease]. / Efecto de un programa de entrenamiento físico en la ocurrencia de arritmias inducidas por el ejercicio en pacientes con cardiopatía.

Objective: Although physical training has been associated with an increase in survival, its role in reducing Exercise-induced arrhythmias (EIA) in patients with heart disease has not yet been dilucidated. We aim to compare the effect of physical training on the occurrence of EIA in patients with heart disease. Methodology: We evaluated a retroprospective and self-controlled cohort of patients older than 18 years with heart disease who entered the cardiac rehabilitation program of the National Institute of Cardiology Ignacio Chávez in México, during January 2015 to December 2016. In all patients, cardiovascular risk was stratified, including a cardiopulmonary exercise test, which was also performed at the end of the program. The occurrence of arrhythmias was evaluated before and after the training program. Results: 160 patients were analyzed, of which 126 (79%) were male. The proportion of patients who developed EIA in the first exercise testing was 56% and in the second one was 48%. In the first group 35% of patients did not developed EIA in the second test. Of the 71 patients who did not present EIA at the beginning of the program, twenty (28%) presented arrhythmias at second test. In relation to the effect of the training program on the occurrence of arrhythmias, we could observe that it had a protective effect, with a RR = 0.49 (95% CI: 0.35-0.67, p <0.001). Conclusion: In this study, physical training was associated with a decreased risk of developing EIA.

Seventy-five years of cardiovascular rehabilitation in Mexico.

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 1940s 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 complexes 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. At present, these programs have spread throughout the Mexican Republic thank 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.

Los pacientes que sufren una enfermedad cardiovascular requieren de atención médica integral que involucre las terapias y procedimientos necesarios para reintegrarlos de forma óptima a su vida personal, familiar, laboral y social. Las intervenciones dirigidas a alcanzar dichas metas se incluyen en los programas de rehabilitación cardiaca. Estos programas son diseñados para limitar los efectos dañinos tanto fisiológicos como psicológicos de las cardiopatías, reducir el riesgo de muerte súbita o reinfarto, controlar la sintomatología cardiovascular, estabilizar o revertir el proceso de aterosclerosis y mejorar el estado psicosocial y vocacional de los pacientes. Dichos programas existen en México desde la década de 1940 y han evolucionado a lo largo de los años, adaptándose a las condiciones de enfermedad presentes en nuestro país, desde su inicio con terapias para tratar a pacientes cardiopatía reumática hasta la aplicación del ejercicio físico en pacientes con insuficiencia cardiaca, cardiopatías congénitas complejas o hipertensión arterial pulmonar. Estas actividades son de índole transdisciplinaria e implica la integración de cardiólogos, fisioterapeutas, psicólogos y nutriólogos, entre otros. Actualmente, estos programas se han extendido a lo largo de la República Mexicana gracias a cardiólogos rehabilitadores egresados de las principales instituciones de salud del país, como son los Institutos de Salud, el IMSS (Instituto Mexicano del Seguro Social) y el ISSSTE (Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado). En este documento se expondrán los orígenes de la rehabilitación, desde la época prehispánica hasta la actual, destacando las contribuciones en docencia e investigación de los médicos que han ejercido en esta área en las instituciones previamente mencionadas.

Association between premature ventricular complexes during exercise, long-term occurrence of life-threatening arrhythmia and mortality.

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.

National Registry of Cardiac Rehabilitation Programs in Mexico II (RENAPREC II).

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: 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.

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.
