RESUMEN

Objective: To assess adherence to the recommendations for the diagnosis and management of hospitalized patients with Decompensated Heart Failure issued by the European Society of Cardiology in 2021 at a Coronary Care Unit at a fourth-level hospital in the city of Bogotá. Materials and Methods: A descriptive cross-sectional study was conducted, including hospitalized patients in the Coronary Care Unit at Hospital San José in Bogotá, with a primary diagnosis of Decompensated Heart Failure, from September 2021 to January 2023. Patient data were collected from medical records. Adherence to the Decompensated Heart Failure guidelines was described in the study. Results: High adherence was observed for laboratory tests and medication prescriptions recommended by the 2021 European Society of Cardiology guidelines. However, there was low adherence to the request for thyroid function tests, troponin, and iron studies. The cause of heart failure and decompensation was adequately recorded. The most common cause of decompensation was acute coronary syndrome. Regarding the hemodynamic profile on admission, the majority presented as Stevenson B. Pharmacological adherence to Class I recommendations showed high compliance in prescribing beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and Angiotensin Receptor-Neprilysin Inhibitors. However, lower adherence was observed for Sodium-glucose co-transporter two inhibitors and Mineralocorticoid receptor antagonists. Conclusions: Variable adherence rates were recorded, emphasizing satisfactory compliance with class I recommendations for certain medications and laboratory tests. It is necessary to improve adherence in the request for paraclinicals, especially in thyroid function tests and ferrokinetic profiles.

RESUMEN

Resumen Introducción: la hipertensión arterial es uno de los factores principales de morbimortalidad cardiovascular, con una prevalencia en aumento, por lo cual se considera como uno de los factores principales prevenibles y tratables de mortalidad1. En Colombia no se cuenta con datos que correlacionen cambios ecocardiográficos con los valores obtenidos en el monitoreo ambulatorio de presión arterial en 24 horas. Objetivo: evaluar las posibles relaciones entre la presión arterial sistólica y diastólica promedio en 24 horas con los desenlaces: grosor relativo de pared (GRP), volumen auricular izquierdo indexado, fracción de eyección ventricular izquierda (FEVI) y masa ventricular indexada. Materiales y métodos: estudio observacional, descriptivo, de corte transversal, en pacientes colombianos con datos ecocardiográficos y resultados de MAPA del servicio de cardiología del Hospital de San José, entre junio de 2018 y diciembre de 2019. Resultados: se incluyeron 70 pacientes; se encontró posible relación entre la presión arterial sistólica promedio en 24 horas y el volumen auricular izquierdo indexado (p = 0.004), la presión arterial diastólica promedio en 24 horas y el grosor relativo de pared (p = 0.032). Conclusión: en este estudio se encontró una posible asociación entre volumen auricular izquierdo y presión arterial sistólica promedio en 24 h, GRP y presión arterial diastólica promedio en 24 h. Se hacen necesarios más estudios para confirmar estos hallazgos.

Abstract Introduction: Arterial hypertension is one of the main factor associated with cardiovascular morbidity and mortality with increasing prevalence, so it is considered as a key factor to treat to decrease cardiovascular disease. There is no data in Colombia that correlates echocardiographic parameters with meassures of blood pressure obtained by a 24 h ambulatory blood pressure monitoring. Objective: To evaluate possible relations between 24 hour blood pressure monitoring and relative wall thickness, left atrial volume index, left ventricular ejection fraction and ventricular mass index. Materials and methods: A cross sectional, observational, descriptive trial in Colombian patients between june 2018 to dicember 2019 with echocardiographic and 24 h blood pressure monitoring data from the cardiology deparment of the Hospital de San José. Results: 70 patients were included. a possible relation was found between 24 h systolic blood pressure monitoring and 24 h diastolic pressure monitoring with left atrial volume index (p = 0.004) and relative wall thickness (p = 0.032) respectively. Conclusion: A possible association was found between 24 h systolic blood pressure monitoring and 24 h diastolic blood pressure monitoring with left atrial volume index and relative wall thickness respectively. It is necessary to conduct more studies to confirm this finding.

RESUMEN

Background: Chagas cardiomyopathy (CC) increases cardiovascular mortality associated with congestive heart failure (CHF), ventricular arrhythmias (VA), and sudden cardiac death (SCD). Different imaging techniques have been tested to assess disease progression and cardiac risk in individuals with Chagas disease (ChD). In this systematic review, we evaluated the accuracy in detecting cardiac complications in CC patients using cardiac magnetic resonance (CMR) and speckle tracking echocardiography (STE). Methods: A search was done on PubMed, Cochrane, and Embase for studies in humans over 18 years of age with ChD. Demographic data, research methodology, imaging parameters, and cardiac outcomes were extracted, and study quality was assessed, resulting in a narrative description. Results: Twelve studies with 1124 patients were analyzed. One study discovered a contractility pattern by STE. Four studies assessed the identification of Early Cardiac Impairment (ECI) and VA risk, respectively, while three studies evaluated the risk of SCD. Global Longitudinal Strain (GLS) identified patients with ECI (-18.5 ± 3.4% non-fibrosis vs -14.0 ± 5.8% fibrosis, p = 0.006 and -18 ± 2% non-fibrosis vs -15 ± 2% fibrosis, p = 0.004). The amount of fibrosis > 11.78% or in two or more contiguous transmural segments were markers for VA risk. GLS and the amount of fibrosis were found to be predictors of SCD. Conclusions: STE may be considered a screening technique for identifying the subclinical status of CHF. CMR using Late Gadolinium Enhancement (LGE) is considered a relevant parameter for stratifying patients with ChD who are at risk of SCD. Fibrosis and GLS can be used as markers to categorize patients at risk for arrhythmias.

RESUMEN

BACKGROUND AND AIMS: Autoimmune diseases (AID) share various clinical signs and symptoms and pathophysiological mechanisms including the increased risk of cardiovascular disease. The coronary artery calcium score (CACS) is potentially useful in improving the cardiovascular risk assessment. The aim of this study was to evaluate CACS in six AIDs analyzed as a group compared with controls through a systematic literature review (SLR) and meta-analysis. METHODS: A literature search (Medline/OVID, Lilacs, Embase, and Cochrane/OVID) up to January 6, 2021 was made (PROSPERO CRD42020197182). Observational studies (patients with six AIDs: rheumatoid arthritis [RA], systemic lupus erythematosus [SLE], Sjögren's syndrome, systemic sclerosis, dermatopolymyositis, and antiphospholipid syndrome) compared with controls were included. CACS, reported in Agatston units, was the primary outcome in both groups. Mean differences and a random-effects model (DerSimonian and Laird) were calculated. RESULTS: Nineteen articles were meta-analyzed (4568 subjects: 2142 AID and 2426 controls). Mean age was 48.1 and 44.2 years, respectively and 75.6% and 84.9% were women, respectively. Of cases, 52.9% had RA, 44.4% SLE and 2.7% had systemic sclerosis. The pooled analysis showed a higher CACS in patients with AIDs (7.42; 95% CI 1.79 to 13.05; chi2-p = 0.01) compared with controls. Meta-regression models showed that age in cases and controls reduced the difference in CACS between groups (p < 0.05), HDL had an inverse relationship (p = 0.04), and CRP levels had a directly proportional relationship with CACS in cases (p = 0.036). CONCLUSIONS: The quantitative results of this meta-analysis suggest that CACS is higher in patients with AID, possibly due to chronic exposure to pro-inflammatory molecules. These results have clinical implications since the finding of highly elevated CACS in patients with AID will enable physicians and researchers to develop a risk stratification model that includes CACS as one of the screening tools for detecting coronary atherosclerosis in these patients.

RESUMEN

Resumen El origen anómalo de la arteria coronaria izquierda desde la arteria pulmonar o, por su sigla en inglés, síndrome de ALCAPA (Anomalous origin of the Left Coronary Artery from the Pulmonary Artery), también conocido como síndrome Bland-White-Garland es una rara cardiopatía congénita; sin embargo, es una de las causas más comunes de falla cardiaca, isquemia e infarto de miocardio en niños, que, en ausencia de tratamiento, alcanza una tasa de mortalidad del 35 al 85 % en el primer año de vida. Hay dos tipos de síndrome de ALCAPA, aquel que se presenta en infantes y el que ocurre en adultos. El segundo tipo es raro y puede manifestarse como infarto de miocardio, disfunción ventricular izquierda e insuficiencia mitral, o isquemia silente que podría llevar a muerte súbita. Se presenta el caso de una paciente de 30 años, con cardiopatía dilatada y disfunción ventricular severa, secundaria a síndrome de ALCAPA, y el caso de un paciente de 61 años con cuadro de dolor torácico en quien se documentó el mismo síndrome.

Abstract The anomalous origin of the left coronary artery from the pulmonary artery or its acronym ALCAPA syndrome (Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery), also known as Blande-Whitee-Garland syndrome, is a rare congenital heart disease. However, one of the most common causes of heart failure, ischemia and myocardial infarction in children, which in the absence of treatment, reaches a mortality rate of 35 to 85% in the first year of life. There are two types of ALCAPA syndrome, that occurs in infants and adults. The presentation of the second type is rare and can manifest as myocardial infarction, left ventricular dysfunction and mitral insufficiency, or silent ischemia that could lead to sudden death. We present the case of a 30-year-old patient with dilated cardiomyopathy and severe ventricular dysfunction, secondary to the ALCAPA syndrome, another case of a 61-year-old patient with chest pain where the mentioned syndrome was documented.

RESUMEN

Abstract Introduction: infective endocarditis is a disease characterized by infection of the endocardial surface of the heart, especially the valves. Given the change in causal microorganisms, a characterization of this disease is essential in order to obtain our own results. Objective: to describe the clinical, microbiological and echocardiographic characteristics, mortality and treatment guidelines of patients with infective endocarditis. Methods: a case series was performed at a quaternary care hospital in Bogotá. The medical records from 2013-2017 of patients with an ICD-10 diagnosis of endocarditis and who were in the cardiology imaging laboratory's database were reviewed. Descriptive statistics were used to report the findings, along with a multiple correspondence analysis to explore the relationship between the type of microorganism and the other variables. Results: data from 34 patients were reviewed. These patients had an average age of 59 years (standard deviation 15.3) and were predominantly males. Native valves were more frequently involved (85.2%), especially the mitral valve (55.8%). The most common clinical finding was fever (64.7%), and vegetations were seen on echocardiogram in 91.2%. The microbiological isolates were predominantly Staphylococcus aureus (32.3%); treatment with antibiotic alone was prescribed for 70.7%, the remaining 29.3% were managed surgically, and there was an 8.8% documented mortality. Discussion and conclusions: the characteristics of this series are similar to those of other series. Staphylococcus aureus is the main causal germ. The low mortality found may be explained by the lower frequency of serious complications requiring surgical management. (Acta Med Colomb 2019; 44. DOI:https://doi.org/10.36104/amc.2019.1223).

Resumen Introducción: la endocarditis infecciosa es una enfermedad caracterizada por el compromiso infeccioso de la superficie endocárdica del corazón, principalmente a nivel valvular. Dado el cambio en los microorganismos causales, se hace indispensable realizar una caracterización de esta patología para obtener resultados propios. Objetivo: describir las características clínicas, microbiológicas, ecocardiográficas, mortalidad y pautas de tratamiento de los pacientes con endocarditis infecciosa. Metodología: de realizó una serie de casos en un hospital de IV nivel, en Bogotá. Se revisaron las historias clínicas de los años 2013- 2017, de los pacientes con diagnóstico de endocarditis por código CIE 10 y en la base de datos del laboratorio de imágenes de cardiología. Se empleó estadística descriptiva para relatar los hallazgos y un análisis de correspondencias múltiples para explorar la relación entre tipo de microorganismo y demás variables. Resultados: se revisaron datos de 34 pacientes, con edad promedio de 59 años (Desviación estándar 15.3), predominio del género masculino, siendo más frecuente en válvulas nativas (85.2%) y de éstas la válvula mitral (55.8%). El hallazgo clínico más frecuente fue la fiebre 64.7%, en ecocardiografía se observó la presencia de vegetación en 91.2%. Los aislamientos microbiológicos evidenciaron predominio de Staphylococcus aureus (32.3%), se indicó manejo exclusivamente antibiótico a 70.7% y el restante 29.3% manejo quirúrgico y se documentó una mortalidad de 8.8%. Discusión y conclusiones: las características de esta serie son similares a las de otras series, Staphylococcus aureus se posiciona como el principal germen causal. La baja mortalidad encontrada puede explicarse por la menor frecuencia de complicaciones graves que requerían manejo quirúrgico. (Acta Med Colomb 2019; 44.

RESUMEN

Resumen La fístula coronaria es una anormalidad de la circulación, que consiste en una comunicación, a través de uno o más ramos, a sitios como el tronco de la arteria pulmonar, el seno coronario, la vena cava, las venas pulmonares, o directamente a una cavidad cardiaca. Es una entidad infrecuente, de causa congénita o adquirida. Debido a su baja incidencia es subdiagnosticada, atribuyendo los síntomas a otras causas. El tratamiento cuando es necesario es la resección quirúrgica o la oclusión percutánea. Se describe un caso en el que el hallazgo de la fistula coronaria se realiza en el contexto de un evento coronario agudo con elevación de segmento ST aumentando la complejidad del enfoque y manejo.

Abstract Coronary fistula consists of an abnormal arterial communication, via one or more branches, to places like the trunk of a pulmonary artery, coronary sinus, vena cava, pulmonary veins or directly to a heart chamber. It is a rare condition, of congenital or acquired origin. Due to their low incidence they are underdiagnosed, symptoms are attributed to other causes. When required, treatment is surgical resection or percutaneous closure. A case where the finding of a coronary fistula is carried out in the context of ST-elevation acute myocardial infarction is described, increasing complexity of management and approach.

RESUMEN

La amiloidosis cardiaca es una manifestación de un grupo de enfermedades sistémicas que se caracteriza por el mal plegamiento de proteínas que causa un depósito extracelular de la amiloide, conocido como amiloidosis. Es una causa importante de las enfermedades infiltrativas, que pueden ser responsables tanto del compromiso cardiaco como de otros órganos. Es importante el reconocimiento de su etiología primaria o secundaria para dar el tratamiento adecuado según su causa. Describimos un caso de un paciente de 69 años de edad, con amiloidosis que ingresa al servicio de urgencias con un bloqueo auriculoventricular completo.

Cardiac amyloidosis is a manifestation of a systemic diseases group characterized by protein misfolding caused by extracellular deposition of amyloid, known as amyloidosis. It is the main cause of infiltrative diseases that can be responsible of cardiac involvement as to other organs. It is important to recognize its primary or secondary etiology to give the appropriate treatment depending of the cause. We describe a case of a 69 year old patient with cardiac amyloidosis debuting in the emergency room with complete atrioventricular block.
