Utilization of medical interventions in hospitalized Mexican adults with cancer at the end of life in a referral hospital: The importance of early palliative care.

OBJECTIVES: To investigate the impact of early vs. late palliative care (PC) on the frequency of admissions to acute hospital settings and the utilization of end-of-life (EoL) interventions in cancer decedents. METHODS: In this single-center, cross-sectional study, we examined the frequency of intensive care unit (ICU) and emergency department (ED) admissions among adult cancer decedents between 2018 and 2022 in a referral hospital in México. Additionally, we assessed EoL medical interventions, categorizing patients into 3 groups: those who received early PC (EPC), late PC (LPC), and those who did not receive PC (NPC). RESULTS: We analyzed data from 1762 patients, averaging 56 ± 16.3 years old, with a predominant representation of women (56.8%). PC was administered to 45.2% of patients, but EPC was limited to only 12.3%. The median time from the initiation of PC to death was 5 days (interquartile range: 2.0-31.5). Hematological malignancies were the most prevalent, affecting 21.5% of patients. EPC recipients demonstrated notable reductions in ICU and ED admissions, as well as diminished utilization of chemotherapy, radiotherapy (RT), antibiotics, blood transfusions, and surgery when compared to both LPC and NPC groups. EPC also exhibited fewer medical interventions in the last 14 days of life, except for RT. SIGNIFICANCE OF RESULTS: The findings of this study indicate that a significant proportion of EoL cancer patients receive PC; however, few receive EPC, emphasizing the need to improve accessibility to these services. Moreover, the results underscore the importance of thoughtful deliberation regarding the application of EoL medical interventions in cancer patients.

Acceleration of infectious disease drug discovery and development using a humanized model of drug metabolism.

A key step in drug discovery, common to many disease areas, is preclinical demonstration of efficacy in a mouse model of disease. However, this demonstration and its translation to the clinic can be impeded by mouse-specific pathways of drug metabolism. Here, we show that a mouse line extensively humanized for the cytochrome P450 gene superfamily ("8HUM") can circumvent these problems. The pharmacokinetics, metabolite profiles, and magnitude of drug-drug interactions of a test set of approved medicines were in much closer alignment with clinical observations than in wild-type mice. Infection with Mycobacterium tuberculosis, Leishmania donovani, and Trypanosoma cruzi was well tolerated in 8HUM, permitting efficacy assessment. During such assessments, mouse-specific metabolic liabilities were bypassed while the impact of clinically relevant active metabolites and DDI on efficacy were well captured. Removal of species differences in metabolism by replacement of wild-type mice with 8HUM therefore reduces compound attrition while improving clinical translation, accelerating drug discovery.

Assessment of emotional distress in palliative care: Edmonton Symptom Assessment System-revised (ESAS-r) vs Distress Thermometer.

OBJECTIVES: To evaluate the sensitivity and specificity of the Distress Thermometer (DT) as a screening tool for emotional distress in oncological palliative care patients and to compare the DT with the Edmonton Symptom Assessment System-revised (ESAS-r) and the gold standard to determine the most appropriate assessment method in palliative psychological care. METHODS: Data were collected from psychological screening tests (ESAS-r and DT), and clinical interviews (gold standard) were conducted by a clinical psychologist specialist in palliative oncology from January 2021 to January 2022 in an oncology palliative care service. RESULTS: The sample consisted of 356 first-time patients with a diagnosis of advanced cancer in palliative care. The most frequently reported oncological diagnoses were gastrointestinal tract (49.3%) and breast (18.3%). Most patients were female (n = 206; 57.9%), 60.4% were married/with a partner, 55.4% had between 6 and 9 years of schooling, and a median age of 57 (range, 46-65) years. The cutoff of the DT was 5, with a sensitivity of 75.88% and specificity of 54.3%. Emotional problems (sadness and nervousness) had a greater area under the curve (AUC) when measured using the DT than the ESAS-r; however, only in the case of the comparative sadness and discouragement was the difference between the AUC marginally significant. SIGNIFICANCE OF RESULTS: The use of the DT as a screening tool in oncological palliative care is more effective in the evaluation of psychological needs than the ESAS-r. The DT, in addition to evaluation by an expert psychologist, allows for a more comprehensive identification of signs and symptoms to yield an accurate mental health diagnosis based on the International Classification of Diseases-11th Revision and/or Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition.

Suicide in cancer patients undergoing palliative care: A report of two cases / Suicidio en pacientes con cáncer que recibe cuidados paliativos: reporte de dos casos

Abstract Introduction Suicide represents a major public health problem worldwide, and cancer patients might have vulnerability factors which increase suicide risk. There are multiple factors associated with this tragic outcome, including those stemming from the disease itself, mental illness and social, personal and spiritual factors. Although previous reports have identified a suicide rate which ranges from .03-7% among cancer patients undergoing palliative care, this has not been studied in Mexico. Objective This study sought to report the cases of suicide in patients with cancer undergoing palliative care at a large cancer reference center. Method A retrospective review of records was performed between 2018-2019 for patients treated at the Palliative Care Service of the Instituto Nacional de Cancerología in Mexico City. Records for patients who committed suicide were reviewed to describe factors associated with this outcome. Results Among all deaths identified during the record review, two were due to suicide (.09%). The patients were one female and one male, 60 and 42 years of age, diagnosed with breast cancer and gastroesophageal junction cancer, respectively, associated with tobacco and alcohol consumption, as well as several economic, social, and familial stress factors. One of the patients was identified as likely having major depressive disorder. Discussion and conclusion Deaths might be underreported in our population. A systematic evaluation is required in order to establish and detect suicidal behavior risk factors, and a follow-up plan for all these patients.

Resumen Introducción El suicidio representa un problema de salud pública en todo el mundo. Los pacientes con cáncer pueden tener factores de vulnerabilidad para presentar conducta suicida. Hay múltiples factores asociados con este fenómeno, incluidos los derivados de la enfermedad en sí, enfermedades mentales y factores sociales, personales y espirituales. Aunque hay reportes previos que describen una tasa de suicidio que va del .03 al 7% entre los pacientes con cáncer que reciben cuidados paliativos, esto no se ha estudiado en México. Objetivo Reportar los casos de suicidio en pacientes oncológicos que reciben cuidados paliativos en un centro oncológico de referencia. Método Se trata de un estudio retrospectivo, donde se revisaron los expedientes de los pacientes atendidos en el Servicio de Cuidados Paliativos del Instituto Nacional de Cancerología entre 2018-2019. Se revisaron los expedientes de los pacientes que se suicidaron para describir los factores de riesgo que presentaban. Resultados Entre todas las muertes identificadas durante la revisión de expedientes, dos se debieron a suicidio (.09%). Los pacientes fueron una mujer y un hombre, de 60 y 42 años, diagnosticados de cáncer de mama y de una unión gastroesofágica, respectivamente. Los factores asociados fueron el consumo de tabaco y alcohol, así como varios factores de estrés económico, social y familiar. Se identificó, asimismo, que uno de los pacientes padecía trastorno depresivo mayor. Discusión y conclusión Es posible que los suicidios estén infrarreportados en nuestra población. Se requiere una evaluación sistemática para establecer y detectar factores de riesgo de conducta suicida, y un plan de seguimiento para todos estos pacientes.

Association between new-onset right bundle branch block and primary or secondary ventricular fibrillation in ST-segment elevation myocardial infarction.

AIMS: New-onset right bundle branch block (RBBB) in myocardial infarction (MI) is often associated with ventricular fibrillation (VF) but the nature of this relationship has not been determined. METHODS AND RESULTS: Between 1998 and 2014, among other data, incidence and duration of RBBB and VF occurrence were prospectively collected in 5301 patients with ST-segment elevation MI (STEMI) admitted to two University Hospitals in Murcia (Spain). Multinomial adjusted logistic regression analyses were used to examine the association between RBBB, attending to its duration, and VF according to its primary VF (PVF) or secondary VF (SVF) character. Among 284 (5.4%) patients with new-onset RBBB, 158 were transient and 126 permanent. VF occurred in 339 (6.4%) patients, 201 PVF and 138 SVF, documented within the first 2 h of symptoms-onset in 78% and 60%, respectively. New-onset RBBB was more frequent in PVF (11.4%) and SVF (20.3%), than in non-VF (4.7%). Transient RBBB incidence was higher in PVF (9.0%) and SVF (9.4) than in non-VF (2.6%), whereas permanent RBBB was higher in SVF (10.9%) than PVF (2.5%) and non-VF (2.1%). New-onset RBBB 1.83 [95% confidence interval (CI): 1.07-3.11] and new-onset transient RBBB 2.39 (95% CI: 1.32-4.32) were independently associated with PVF. New-onset 3.03 (95% CI: 1.83-5.02), transient 2.40 (95% CI: 1.27-4.55), and permanent 2.99 (95% CI: 1.52-5.86) RBBB were independently associated with SVF. CONCLUSION: New-onset RBBB and VF in STEMI are independently associated and show particularities based on the duration of the conduction disturbance and/or the primary or secondary character of the arrhythmia.

Associated factors of distress in patients with advanced cancer: A retrospective study.

OBJECTIVE: The objective of this study was to assess the psychosocial distress and associated factors in advanced cancer patients consulting at the outpatient Palliative Care Unit at the National Cancer Institute in Mexico City. DESIGN: A retrospective study was conducted using electronic records (June 2015 to December 2016). SAMPLE: A total of 646 patients with advanced cancer during their first visit to the outpatient palliative care unit at the National Cancer Institute in Mexico were evaluated using the Distress Thermometer (DT) and ECOG performance status scores. FINDINGS: Overall, 62% were women, with a median age of 57 years, and married (54.8%). The most frequent diagnosis was gastrointestinal cancer (28.6%), and 38.9% had a functional performance status of ECOG 2. The median DT score was 4.0 (IQR = 2-6), with 56% reporting DT scores ≥4. The three most frequent problems ≥4 were sadness (82.6%), feeling weak (81.2%), worry (79.6%), and <4 were feeling weak (57.7%), fatigue (55.6%), and financial security (52.1%). The variables associated with distress according to the multiple logistic regression analysis were problems with housing (OR = 2.661, 95% CI = 1.538-4.602), sadness (OR = 2.533, 95% CI = 1.615-3.973), transportation (OR = 1.732, 95% CI = 1.157-2.591), eating (OR = 1.626, 95% CI = 1.093-2.417), nervousness (OR = 1.547, 95% CI = 1.014-2.360), and sleep (OR = 1.469, 95% CI = 1.980-2.203). CONCLUSION: The principal factors were related to distress levels, housing problems, transportation issues, and emotional problems such as sadness, nervousness, lower functionality, and younger age. Therefore, psychosocial support is of considerable relevance in palliative care. These findings will help clinicians understand the distress of patients with advanced cancer in palliative care in Latin American countries.

Recommendations for the provision of palliative care to people with COVID-19.

The pandemic of SARS-CoV-2 infection, which causes COVID-19, has deeply affected health systems and has had a significant impact on families, communities and nations. A comprehensive response strategy requires, in addition to epidemiological, scientific and technical considerations, for human suffering associated with disease, vulnerability and death not to be forgotten. Palliative care for people with suspicion or diagnosis of COVID-19 with serious evolution, and their families should also be a key part of organized actions that help alleviate suffering and improve quality of life by controlling symptoms, addressing psychological, emotional, social and spiritual needs, support for advanced care planning and its goals, end-of-life care, as well as support in complex decision-making and ethical problems, among others. Recommendations are provided for offering palliative care in COVID-19 pandemic context.

La pandemia de infección por SARS-CoV-2, la cual es causada por COVID-19, ha afectado profundamente a los sistemas de salud y ha ocasionado un enorme impacto en las familias, las comunidades y las naciones. La estrategia de respuesta integral requiere que además de las consideraciones epidemiológicas, científicas y técnicas, no se olvide el sufrimiento humano asociado a la enfermedad, la vulnerabilidad y la muerte. La atención paliativa a personas con sospecha o diagnóstico de COVID-19 con evolución grave y sus familias debe ser también parte clave de la acción organizada que ayude al alivio del sufrimiento y mejore la calidad de vida mediante el control de los síntomas, el abordaje de las necesidades psicológicas, sociales y espirituales, el apoyo para la planificación de la atención avanzada y la articulación de los objetivos de la misma, el cuidado de la persona en la fase final de la vida, así como el soporte ante la toma de decisiones complejas y problemas éticos, entre otros. Se ofrecen recomendaciones para brindar los cuidados paliativos en el contexto de la pandemia de COVID-19.

The desire to hasten death in advanced cancer patients at a Mexican palliative care service / Deseos de adelantar la muerte en pacientes con cáncer avanzado en un servicio de cuidados paliativos en México

Abstract Introduction The desire to hasten death (DHD) might be present in patients with advanced cancer. Multiple distressing physical and psychosocial symptoms may be related to it. There is limited literature about the characteristics of these patients in México. Objective To describe the prevalence and factors associated with DHD in advanced cancer patients evaluated by a palliative care psychiatrist. Method We conducted a cross-sectional study, including all patients referred to psychiatric assessment at the Servicio de Cuidados Paliativos of the Instituto Nacional de Cancerología in Mexico City, from January to December 2016. DHD was defined as the presence of death ideas, suicidal ideation, and/or request for euthanasia or medically assisted suicide. Patients with delirium, dementia, psychosis, or uncontrolled physical symptoms were excluded. Results Sixty-four patients were included in the study. Most of them were women (59%); the mean age was 49 years old (SD = 16). Of them, 64% met criteria for a major depressive disorder, 64% for generalized anxiety disorder and/or panic disorder, and 11% for substance use disorders. 44% expressed DHD. In a multivariate regression analysis predicting DHD, only one factor emerged: clinical depression (OR = 13.5, p = .002, 95% CI [02.562, 71.726]). Discussion and conclusion The desire to hasten death is a frequent issue for the patients evaluated at the psychiatric palliative care clinic. Depression and other distressing psychiatric pathologies were associated with DHD. Interdisciplinary interventions are needed to treat DHD. More research is warranted in order to understand the factors associated with the expression of DHD.

Resumen Introducción El deseo de acelerar la muerte (DHD, por sus siglas en inglés) es frecuente en pacientes con cáncer avanzado. Múltiples estresores físicos y psicosociales se asocian a la presencia de este fenómeno. En México es limitada la información sobre estos pacientes. Objetivo Describir la prevalencia y los factores asociados con la presencia del DHD en pacientes con cáncer avanzado evaluados por el psiquiatra de cuidados paliativos. Método Realizamos un estudio transversal, incluimos a todos los pacientes referidos a evaluación psiquiátrica en el Servicio de Cuidados Paliativos del Instituto Nacional de Cancerología en la Ciudad de México, de enero a diciembre de 2016. El DHD se definió como la presencia de ideas de muerte, ideación suicida y/o solicitud de eutanasia o suicidio médicamente asistido. Se excluyeron los pacientes con delirium, demencia, psicosis o algún síntoma físico descontrolado. Resultados Sesenta y cuatro pacientes fueron incluidos en el estudio; 59% fueron mujeres; la edad media era de 49 años (DE = 16). El 64% cumplieron criterios para un trastorno depresivo mayor, el 64% para el trastorno de ansiedad generalizada y/o trastorno de pánico y el 11% para los trastornos por uso de sustancias; 44% expresaron DHD. En un análisis de regresión multivariable, el factor depresión mayor (OR = 13.5; p = .002, IC 95% [02.562, 71.726]) fue el único significativo. Discusión y conclusión El DHD es frecuente en los pacientes valorados por psiquiatría de cuidados paliativos. La depresión mayor se asoció con DHD. Se necesitan intervenciones interdisciplinarias para tratar el DHD. Se requiere más investigación para comprender los factores asociados con la expresión de DHD.

Validation of the Brief Edinburgh Depression Scale (BEDS) in a Mexican population with advanced cancer in a palliative care service.

OBJECTIVE: Depression in palliative advanced cancer patients is common, but often goes unrecognized. One of the first steps toward improving detection is the development of tools that are valid in the specific language and setting in which they are to be used. The Brief Edinburgh Depression Scale (BEDS) is a sensitive case-finding tool for depression in advanced cancer patients that was developed in the United Kingdom. There are no validated instruments to identify depression in Mexican palliative patients. Our aim was to validate the Spanish-language version of the BEDS in Mexican population with advanced cancer. METHOD: We conducted a cross-sectional study with outpatients from the palliative care unit at the Instituto Nacional de Cancerología in Mexico City. The Mexican BEDS was validated against a semistructured psychiatric clinical interview according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition, classification criteria for major depressive disorder. The interviewer was blind to the BEDS score at the time of the assessment. RESULT: Seventy subjects completed the scale and interview. Women represented 71.4% of the sample and median age of subjects was 56.5 years (range, 20-85 years). The prevalence of major depressive disorder according to the psychiatric interview was 20%. The most valid cutoff for defining a case of depression was a score ≥5 of 18 on the Mexican BEDS, which gave a sensitivity of 85.7% and specificity of 62.5%. The scale's Cronbach's alpha was 0.71. SIGNIFICANCE OF RESULTS: Major depressive disorder is frequent in Mexican palliative patients. The Spanish-language Mexican version of the BEDS is the first valid case-finding tool in advanced cancer patients in this setting.

Effect of part-time cardiac catheterization facilities in patients with acute myocardial infarction.

BACKGROUND: Although the easy availability of invasive cardiac care facilities is associated with an increase in their use, their influence on outcomes is not clear. We sought to investigate whether a newly available cardiac catheterization laboratory (CCL) performing percutaneous coronary intervention (PCI) on a part-time (PT) basis might improve outcomes in patients with acute myocardial infarction (AMI). METHODS: This was an observational cohort study that included all consecutive patients with AMI admitted to a secondary-level hospital in Spain before and after the PT-CCL opened in January 2006: during 1998-2005 and 2006-2014, respectively. All-cause in-hospital and long-term mortality were the co-primary endpoints. In-hospital complications and length of stay were secondary endpoints. For the analyses, patients were stratified according to propensity-score (PS) quintiles. RESULTS: A total of 5339 patients were recruited, and 50.3% were managed after the opening of the PT-CCL. The PT-CCL was associated with greater use of PCI (81.2 vs. 32.5%, p<0.001) and guidelines-recommended medication (all p<0.001), lower risk of recurrent angina (PS-adjusted RR=0.160, 95% CI 0.115-0.222) and shorter length of hospital stay (PS-adjusted RR for length of stay <8days=0.357, 95% CI 0.301-0.422). In patients with NSTEMI, PT-CCL was associated with improved long-term survival (PS-adjusted HR=0.764, 95% CI 0.602-0.970). CONCLUSIONS: In patients with AMI, a new PT-CCL was associated with greater use of PCI and guideline-recommended medication, lower risk of recurrent angina and shorter length of hospital stay. In a subset of patients with NSTEMI, PT-CCL was associated with improved long-term survival.

Prognostic Usefulness of the 6-Minute Walk Test in Patients With Severe Aortic Stenosis.

The 6-minute walk test distance (6MWD) has been shown to predict prognosis in selected cohorts of patients with heart failure and outcomes after surgical or transcatheter aortic valve implantation (AVI) in patients with symptomatic severe aortic stenosis (AS). Our objective was to evaluate the association between the 6MWD and outcome in patients with severe AS while remaining under medical treatment. In a prospective observational cohort study, a total of 149 patients diagnosed with severe AS by Doppler echocardiography underwent a 6-minute walk test. The single end point was a composite of all-cause death or hospitalization for heart failure. Patients receiving an AVI were censored from follow-up at the time of their AVI, so that only the events that occurred while the patients remained under medical treatment were included in the analysis. During follow-up (median 12.9 months), the end point occurred in 65 patients (43.6%). Univariate analysis showed an association between the 6MWD and the end point (p <0.001). After adjustment for symptoms, left ventricular ejection fraction, aortic valve area, Charlson co-morbidity score, and anemia, the 6MWD independently predicted the end point (adjusted hazard ratio 0.63; 95% confidence interval 0.45 to 0.89; p = 0.010). The incidence of the composite end point was 12 per 100 patient-years in patients with a 6MWD >331 m compared to 86 per 100 patient-years in those with a 6MWD ≤331 m (p <0.001). In conclusion, although patients with severe AS remain under medical treatment, the 6MWD is independently associated with all-cause death or hospitalization for heart failure.

Effectiveness and Safety of Bivalirudin During Percutaneous Coronary Intervention in Acute Coronary Syndrome in the Real World: CARTAGOMAX Study.

The CARTAGOMAX study assessed the safety and efficacy of bivalirudin during real-world cardiac intervention. This was a single-center prospective study. Patients with acute coronary syndrome undergoing percutaneous coronary intervention were anticoagulated with bivalirudin alone or unfractionated heparin plus a glycoprotein IIb/IIIa inhibitor. Propensity score matching was performed to control for baseline imbalances and yielded 1168 patients. There was lower incidence of the composite outcome of death from any cause or major bleeding at 30 days (P = 0.005), 6 months (P = 0.005), and 12 months (P = 0.001) of follow-up in the bivalirudin group, compared with the heparin plus glycoprotein inhibitor group. The administration of bivalirudin was associated with lower rate of all-cause mortality at 1 year of follow-up (P = 0.009). The incidence of major bleeding was lower in the bivalirudin group at 1, 6, and 12 months of follow-up (P = 0.002, P = 0.013 and P = 0.017, respectively). The incidence of stroke and reinfarction were similar between groups during follow-up. The rate of stent thrombosis were slightly higher in the bivalirudin group, without reaching statistical significance at 1 and 12 months of follow-up (P = 0.06, P = 0.04, P = 0.07 at 1, 6, and 12 months, respectively). The CARTAGOMAX study found that the use of bivalirudin during percutaneous coronary intervention was associated with lower incidence of the composite outcome of death from any cause or major bleeding during follow-up. The use of bivalirudin was associated with similar rates of stroke, reinfarction, and stent thrombosis compared with heparin plus glycoprotein inhibitor. Bivalirudin proved to be a safe and effective anticoagulant during percutaneous coronary intervention.

Relation of New Permanent Right or Left Bundle Branch Block on Short- and Long-Term Mortality in Acute Myocardial Infarction Bundle Branch Block and Myocardial Infarction.

The aim of this study was to investigate the prognosis associated with bundle branch block (BBB) depending on location, time of appearance, and duration in patients with myocardial infarction (MI). From January 1998 to January 2008, we recruited 5,570 patients with acute MI. Thirty-day and 7-year all-cause mortality, according to BBB location, time of appearance, and duration were analyzed by multivariable analyses. BBB was present in 964 patients (17.3%); right BBB (RBBB) 10.6% and left BBB (LBBB) 6.7%. Overall mortality rate at 30 days was 13.2% (n = 738) and 7 years was 6.34 deaths per 100 patient-year. Both RBBB and LBBB were more frequently previous, 42.9% and 58.8%. Compared with non-BBB, all BBB groups showed higher prevalence of co-morbidities, especially rates of diabetes (49.0% vs 34.3%, p <0.001) and more often heart failure during hospitalization (54.5% vs 26.6%, p <0.001). Compared with RBBB, patients with LBBB had a higher prevalence of co-morbidities and a higher mortality, especially the new BBB, 30 days: 52.5% versus 31.6% and 7 years (incident rate): 27.2 versus 13.3 per 100 patient-year. New transient BBB had lower heart failure on admission (42.6% vs 58.3%, p = 0.008) and 30-day mortality (20.3% vs 69.6%, p <0.001) compared with permanent in both locations. New permanent RBBB was independently associated with 30-day (hazard ratio [HR] 2.01, 95% confidence interval [CI] 1.45 to 2.79) and 7-year mortality (HR 3.12, 95% CI 2.38 to 4.09). New-permanent LBBB was independently associated with 30-day (HR 2.15, 95% CI 1.47 to 3.15) and 7-year mortality (HR 2.91, 95% CI 2.08 to 4.08). In conclusion, in patients with acute MI, the appearance of a new BBB was independently associated with a higher 30-day and 7-year all-cause mortality.

Educational Level and Long-term Mortality in Patients With Acute Myocardial Infarction.

INTRODUCTION AND OBJECTIVES: The value of socioeconomic status as a prognostic marker in acute myocardial infarction is controversial. The aim of this study was to evaluate the impact of educational level, as a marker of socioeconomic status, on the prognosis of long-term survival after acute myocardial infarction. METHODS: We conducted a prospective, observational study of 5797 patients admitted to hospital with acute myocardial infarction. We studied long-term all-cause mortality (median 8.5 years) using adjusted regression models. RESULTS: We found that 73.1% of patients had primary school education (n=4240), 14.5% had secondary school education (including high school) (n=843), 7.0% was illiterate (n=407), and 5.3% had higher education (n=307). Patients with secondary school or higher education were significantly younger, more were male, and they had fewer risk factors and comorbidity. These patients arrived sooner at hospital and had less severe heart failure. During admission they received more reperfusion therapy and their crude mortality was lower. Their drug treatment in hospital and at discharge followed guideline recommendations more closely. On multivariate analysis, secondary school or higher education was an independent predictor and protective factor for long-term mortality (hazard ratio=0.85; 95% confidence interval, 0.74-0.98). CONCLUSIONS: Our study shows an inverse and independent relationship between educational level and long-term mortality in patients with acute myocardial infarction.

[Prognostic importance of cardiomegaly in patients with acute myocardial infarction]. / Importancia de la presencia de cardiomegalia en el pronóstico de los pacientes con infarto agudo de miocardio.

OBJECTIVES: To assess the in-hospital and long-term prognostic importance of cardiomegaly demonstrated by a simple admission radiograph in patients hospitalized for acute myocardial infarction. MATERIAL AND METHODS: Prospective study of 7644 patients admitted for acute myocardial infarction; 2 hospitals participated. We recorded detailed clinical data, especially noting the presence or absence of cardiomegaly in the chest radiograph. Adjusted predictive models for all-cause mortality in hospital or after discharge were constructed. The median followup was 6 years. RESULTS: Cardiomegaly was detected in 1351 (17.7%) of the patients. Hospital mortality was 11.2% overall; the incidence of long-term mortality was 5.7 per 100 patient-years. Patients with cardiomegaly were older and had more cardiovascular risk factors other than current smoking; they also had more concomitant conditions, had undergone fewer revascularization procedures, and received suboptimal care after discharge. Cardiomegaly was associated with higher in-hospital rates of adverse events, especially heart failure (70.8% in patients with cardiomegaly vs 21.4% in others, P<.001) and death (27.8% vs 7.7%, P<.001). Cardiomegaly was also an independent predictor of hospital mortality (odds ratio, 1.34; P=.02) as well as mortality after discharge (hazard ratio, 1.16; P<.01). CONCLUSION: Cardiomegaly was an independent predictor of both hospital mortality and long-term mortality after discharge in this series.

OBJETIVO: Conocer el significado pronóstico intrahospitalario y a largo plazo de la presencia de cardiomegalia en la radiología simple inicial de los pacientes ingresados por infarto agudo de miocardio. METODO: Estudio prospectivo de 7.644 pacientes ingresados por un infarto agudo de miocardio en dos hospitales. Se obtuvo información clínica detallada y se prestó especial atención a la presencia/ausencia de cardiomegalia en la radiografía de tórax. Realizamos modelos ajustados para predecir mortalidad (por cualquier causa) hospitalaria y tras el alta con una mediana de 6 años. RESULTADOS: 1.351 (17,7%) pacientes presentaron cardiomegalia. La mortalidad hospitalaria global fue 11,2% y la densidad de incidencia de mortalidad a largo plazo fue de 5,7 por cada 100 pacientes-año. Los pacientes con cardiomegalia presentaron mayor edad y más factores de riesgo cardiovascular excepto tabaquismo activo, mayor comorbilidad, fueron menos revascularizados y tratados al alta de forma subóptima. Durante la hospitalización, la cardiomegalia se asoció a mayores tasas de complicaciones, especialmente insuficiencia cardiaca (70,8 vs 21,4%, p < 0,001) y mortalidad (27,8 vs 7,7%, p < 0,001). La cardiomegalia resultó predictor independiente sobre la mortalidad hospitalaria (odds ratio = 1,34; p = 0,02) y tras el alta (hazard ratio = 1,16, p < 0,01). CONCLUSIONES: En pacientes con infarto agudo de miocardio la cardiomegalia resultó predictor independiente de mortalidad hospitalaria y a largo plazo tras el alta.
