RESUMO
Heart failure (HF) is a major clinical and public health problem associated with significant mortality, morbidity, and health-care costs. Despite the existence of evidence-based guidelines for the optimal treatment of HF, the quality of care remains suboptimal. Our aim was to increase the use a care bundle in 50% of enrolled subjects during their hospitalization and discharge and to reduce their readmission for HF causes by 10%. We conducted an uncontrolled before-after study in eight hospitals in Argentina to evaluate the effect of a quality improvement intervention on the use of an HF care bundle in patients with HF New York Heart Association (NYHA) Class II-III. The HF bundle of care included medication, continuum of care, lifestyle habits, and predischarge examinations. Training and follow-up of multidisciplinary teams in each center were performed through learning sessions and plan-do-study-act improvement cycles. Data collectors reviewed bundle compliance in the health records of recruited patients after their hospital discharge and verified readmissions through phone calls to patients within 30-40 days after discharge. We recruited 200 patients (83 before and 127 during the intervention phase), and bundle compliance increased from 9.6% to 28.3% [odds ratio 3.71, 95% confidence interval (8.46; 1.63); P = .002]. Despite a slow improvement during the first months, bundle compliance gained momentum near the end of the intervention surpassing 80%. We observed a non-significant decreased readmission rate within 30 days of discharge due to HF in the postintervention period [8.4% vs. 5.5%, odds ratio 0.63, 95% CI (1.88; 0.21); P = .410]. Qualitative analysis showed that members of the intervention teams acknowledged the improvement of work organization and standardization of care, teamwork, shared mental model, and health record completeness as well as the utility of training fellows. Despite the challenges related to the pandemic, better care of patients with HF NYHA Class II-III was possible through simple interventions and collaborative work. Graphical abstract.

OBJECTIVES: The aim of this study was to develop consensus among Argentine cardiologists on a care bundle to reduce readmissions of patients with heart failure (HF). SETTING: Hospitals and cardiology clinics in Argentina that provide in-hospital care for patients with HF. PARTICIPANTS: Twenty-four cardiology experts participated in the two online rounds and 18 (75%) of them participated in the third-round meeting. METHODS: This study used a mixed-method design; it was conducted between August 2019 and January 2020. The development of a care bundle (a set of evidence-based interventions applied to improve clinical outcomes) involved three phases: (1) a literature review to define the list of interventions to be evaluated; (2) a modified Delphi panel to select interventions for the bundle and (3) definition of the HF care bundle. Also, the process included three rounds of scoring. RESULTS: Twenty-six interventions were evaluated. The interventions in the final bundle covered four categories: medication, continuum of care, lifestyle habits, predischarge tests. These were: medication: beta-blockers, angiotensin receptor neprilysin inhibitors or ACE-inhibitors, furosemide and antimineralocorticoids; continuum of care: follow-up appointment, daily weight monitoring; lifestyle habits: smoking cessation counselling and low-sodium diet; predischarge tests: renal function, ionogram, blood pressure control, echocardiogram and determination of decompensating cause. CONCLUSION: Following a systematic mixed-method approach, we have developed a care bundle of interventions that could decrease readmission of patients with HF. The application of this bundle could contribute to scale evidence-based interventions.

Introducción: El diagnóstico etiológico en pacientes con miocardiopatías en estadio avanzado puede ser un desafío. Un gran número de pacientes permanecen sin diagnóstico a pesar de una evaluación exhaustiva, por lo que quedan rotuladas como miocardiopatías dilatadas idiopáticas. Objetivos: Describir la etiología de la miocardiopatía en pacientes receptores de trasplante cardíaco según el diagnóstico clínico pretrasplante y su grado de concordancia con el diagnóstico anatomopatológico del corazón explantado. Material y métodos: Se realizó un análisis retrospectivo de pacientes consecutivos trasplantados en un hospital de alta complejidad de la Ciudad Autónoma de Buenos Aires desde 2003 hasta fines de 2013. Se efectuó un análisis de concordancia entre el diagnóstico clínico pretrasplante y el diagnóstico anatomopatológico del corazón explantado utilizando el coeficiente kappa. Resultados: Se analizaron 100 pacientes con una edad media en el momento del trasplante de 49,7 ± 12,5 años y una mediana de fracción de eyección del 26,6%. El diagnóstico clínico pretrasplante más frecuente fue el de miocardiopatía dilatada idiopática (37%), seguida por la miocardiopatía isquémico-necrótica (32%) y la miocardiopatía chagásica (10%). Entre los diagnósticos histopatológicos más frecuentes se encontraron el de miocardiopatía isquémico-necrótica (35%), de miocardiopatía hipertrófica (10%), de miocardiopatía chagásica (10%) y de miocarditis (8%); no se arribó a un diagnóstico causal en el 25% (miocardiopatía dilatada idiopática). El resultado del coeficiente kappa fue de 0,64 (IC 0,52-0,76). Conclusiones: Aproximadamente un tercio de los pacientes llegan al trasplante sin un diagnóstico etiológico. El análisis anatomopatológico permite identificar la causa en más de la mitad de estos pacientes. A pesar de que la concordancia entre el diagnóstico pretrasplante y la anatomía patológica fue estadísticamente buena, un porcentaje importante de pacientes podría beneficiarse con un diagnóstico etiológico más preciso, que podría tener implicaciones pronósticas, terapéuticas y/o en la evaluación de familiares.
Introduction: Etiologic diagnosis in patients with end-stage cardiomyopathy can be challenging. A large number of patients remain undiagnosed despite a thorough evaluation, so they are classified as idiopathic dilated cardiomyopathies. Objectives: To describe the etiology of cardiomyopathy in heart transplant recipients according to pretransplant clinical diagnosis and its degree of agreement with the anatomopathological diagnosis of the explanted heart. Methods: We performed a retrospective analysis of consecutively transplanted patients in a high complexity hospital of the Autonomous City of Buenos Aires from 2003 to the end of 2013. An agreement analysis between pretransplantation clinical diagnosis and anatomopathological diagnosis of the explanted heart was done using the kappa coefficient. Results: One-hundred patients with mean age of 49.7 ± 12.5 years at the time of transplantation and median ejection fraction of 26.6% were analyzed. The most common pretransplant clinical diagnosis was idiopathic dilated cardiomyopathy (37%), followed by ischemic-necrotic cardiomyopathy (32%) and Chagas cardiomyopathy (10%). The most common histopathological diagnoses were ischemic-necrotic cardiomyopathy (35%), hypertrophic cardiomyopathy (10%), Chagas cardiomyopathy (10%) and myocarditis (8%); a causal diagnosis was not reached in 25% of cases (idiopathic dilated cardiomyopathy). The kappa coefficient was 0.64 (CI 0.52-0.76). Conclusions: Approximately one third of patients reach transplantation without an etiologic diagnosis. Anatomopathological analysis allows identifying the cause in more than half of these patients. Although the correlation between pretransplant diagnosis and pathological anatomy was statistically adequate, a significant percentage of patients could benefit from a more specific etiologic diagnosis, which may have prognostic, therapeutic and/or family assessment implications.

RESUMO
BACKGROUND AND OBJECTIVES: To know the relationship between "vascular age" (VA) and the diagnosis of subclinical atherosclerosis could improve cardiovascular risk stratification. OBJECTIVES: 1) to know the VA in a primary prevention population, and 2) to determine the relationship between VA and the presence of carotid atherosclerotic plaque (CAP). PATIENTS AND METHODS: We calculated VA based on body mass index (BMI). We obtained the difference between VA and chronological age (Delta). The screening of CAP was done by ultrasound. We analyzed the association between quintiles of VA and Delta with the presence of CAP. ROC analysis was performed. RESULTS: In total, 411 patients were included (age 47 [10] years, 54% men). The VA and Delta were 55 (15) and 7 (9) years respectively. In 75% of the patients VA was higher than the chronological age (50%≥ 6 years). Subjects with CAP had significantly higher VA (66 [11] versus 50 [14] years, P<.0001) and Delta (13 [9] versus 5 [7] years, P<.0001) than subjects without CAP. We observed a positive association of quintiles of VA and Delta with the prevalence of CAP. The area under de curve and the optimal cutoff point of VA for the detection of CAP were 0.813 and 60 years, respectively, and for Delta, 0,771 and 11 years, respectively. CONCLUSIONS: The VA based on BMI could be a simple tool to estimate the presence of CAP and improve cardiovascular risk stratification in patients in primary prevention.
