ABSTRACT

Los síndromes coronarios agudos sin lesiones coronarias han cobrado relevancia en los últimos años, pero aún no se dispone de datos locales. Analizamos un registro de pacientes con infarto agudo de miocardio, en 45 centros del país con residencias de cardiología. Se analizaron 1182 participantes de los cuales 33 (2.8%) no presentaron lesiones coronarias en angiografía, mientras que 89.5% tenían lesiones graves y 7.7% lesiones intermedias. La edad promedio de los pacientes sin lesiones coronarias fue 64.5 ± 13.0 años, 69.7% eran varones, sin diferencias respecto a aquellos con enfermedad epicárdica. La presentación electrocardiográfica más frecuente fue la desviación del segmento ST (13 supradesnivel y 10 infradesnivel del segmento). Además, este subgrupo presentó biomarcadores más bajos (CPK pico 203.5 UI/l, rango [RIC] 102- 422.5 vs. 895.5 UI/l RIC 350-1891, p < 0.0001). La mediana de días de internación fue 4.0 (RIC 3-5.5), siendo menor que la del grupo con enfermedad coronaria intermedia y grave (5.5 días, RIC 4-7, y 6 RIC 4-7, p = 0.003). Al alta, aquellos sin lesiones coronarias recibieron menor prescripción de IECA/ARA II (54.6% vs. 78.0% y 79.7%, p = 0.002) y estatinas (78.8% vs. 87.9% y 91.9%, p = 0.017). Ninguno de este subgrupo falleció durante la inter nación. Nuestros datos sugieren que los infartos sin lesiones coronarias significativas son frecuentes en nuestro medio, aunque probablemente se encuentren subdiagnosticados. Si bien su pronóstico parece más favorable, resulta importante señalar que recibieron menos fármacos para prevenir su recurrencia. Nuevos estudios son necesarios para profundizar el conocimiento de esta enfermedad.


Abstract Acute coronary syndromes without coronary lesions have gained relevance in recent years. However, local data on this condition is scarce. We aimed to explore this entity in a National registry of acute myocardial infarction that was carried out prospectively in hospitals with cardiology residence programs from Ar gentina. We included 1182 patients from 45 centers, where 33 did not present coronary lesions on angiography. The mean age was 64.5 ±13.0 and 69.7% were male, without differences compared to participants with epicardial disease. The most common electrocardiographic presentation was ST segment deviation. In addition, presented lower biomarkers (peak CPK 203.5 IU / l, range [IQR] 102-422.5 vs. 895.5 IU / l IQR 350-1891, p < 0.0001). The median hospitalization was 4.0 days (IQR 3-5.5), lower than the group with intermediate and severe coronary disease (5.5 days, RIC 4-7, and 6, RIC 4-7, p = 0.003). At discharge, less use of ACE/ARB (54.6% vs.78.0% y 79.7%, p = 0.002) and statins (78.8% vs. 87.9% y 91.9%, p = 0.017). No deaths during hospitalization were reported. Our data suggested that infarcts without significant coronary lesions are frequent, although they are probably underdiagnosed. Their prognosis seems to be more favorable, but they receive fewer drugs to prevent recurrence. New studies are necessary to deepen the knowledge of the disease.

ABSTRACT

Resumen El infarto de miocardio con arterias coronarias no obstruidas (MINOCA, por sus siglas en inglés) ha ganado importancia en los últimos 20 años gracias a la dilucidación de etiologías fisiopatológicas diferentes de las causas obstructivas del flujo coronario. Diversos estudios han evidenciado una prevalencia variable, la cual es más alta en las mujeres. Se han descrito dos grupos de alteraciones en la reactividad coronaria que afectan el flujo: las causas epicárdicas y las causas microvasculares. El diagnóstico de MINOCA es de exclusión; por lo tanto, inicialmente se deben descartar otras posibles causas de isquemia, como miocarditis, miocardiopatía séptica, choque hipovolémico por trauma o quemaduras, y enfermedades renales o pulmonares. Los reportes y estudios de esta enfermedad suelen incluir pacientes adultos o mayores de 18 años. Se presenta el caso de una paciente de 16 años con antecedente de tetralogía de Fallot corregida en etapa de lactante menor y reemplazo valvular pulmonar con bioprótesis y ampliación del tronco pulmonar a los 11 años, quien ingresó con dolor torácico de características coronarias. Cursó con un diagnóstico de MINOCA por exclusión en una institución de cuarto nivel en Cali, Colombia. El diagnóstico de MINOCA en edad pediátrica es raro; sin embargo, es importante saber acerca de su existencia para brindar a los pacientes el mejor manejo disponible, de manera que se aseguren los mejores desenlaces a largo plazo.


Abstract Myocardial infarction with non-obstructed coronary arteries (MINOCA) has gained importance in the last 20 years, due to the elucidation of physiopathological etiologies different from the obstructive causes of coronary flow. Different studies have shown variable prevalence, being higher in women. Different causes have been evidenced in the studies found in two groups of alterations in coronary reactivity: epicardial causes and microvascular causes. The diagnosis of MINOCA must be a diagnosis of exclusion. Therefore, other possible causes of ischemia, such as myocarditis, septic cardiomyopathy, hypovolemic shock due to trauma or burns, renal or pulmonary diseases, should be ruled out initially. The reports and studies done around this pathology usually include adult patients and people older than 18 years. We present the case of a 16-year-old patient with a history of Tetralogy of Fallot corrected as an infant and pulmonary valve replacement with bioprothesis and enlargement of the pulmonary trunk at 11 years of age who was admitted with chest pain of coronary characteristics. The diagnosis after multiples studies and exclusion of other causes was MINOCA in a fourth level institution in Cali, Colombia.

ABSTRACT

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.

ABSTRACT

Introducción: La actividad física regular puede contribuir a prevenir las enfermedades al mínimo costo posible, especialmente si se plantea como un hábito de vida saludable y no como una actividad de riesgo que requiere una estricta y costosa supervisión médica especializada. Objetivo: Evaluar la influencia del ejercicio físico sobre factores de riesgo de trastornos coronarios en pacientes con cardiopatía isquémica. Métodos: Se realizó una investigación descriptiva de 41 pacientes que habían padecido un infarto agudo de miocardio y que formaron parte de un programa de rehabilitación cardiovascular en el Servicio de Terapia Física y Rehabilitación del Hospital General Docente Dr. Juan Bruno Zayas Alfonso en Santiago de Cuba, desde mayo de 2017 hasta igual mes de 2019. Para ello se seleccionaron los factores de riesgo de trastornos coronarios más frecuentes en la muestra, los cuales fueron analizados antes y después de aplicado el programa. Resultados: Los factores de riesgo predominaron en los hombres (68,4 %), con una mayor incidencia de la hipertrigliceridemia en ambos sexos (56,1 %). Después de aplicada la rehabilitación, se logró una disminución de las cifras de glucemia, triglicéridos y colesterol sérico. Conclusiones: Los programas de rehabilitación cardiovascular mejoran la salud del paciente e igualmente proporcionan beneficios socioeconómicos a la sociedad.


Introduction: Regular physical activity can contribute to prevent diseases at the minimum cost possible, especially if it is a healthy life habit and not a risky activity that requires a strict and expensive specialized medical supervision. Objective: To evaluate the influence of the physical exercise on risk factors of coronary disorders in patients with ischemic heart disease. Methods: A descriptive investigation of 41 patients that had suffered from a heart attack and were part of a program of cardiovascular rehabilitation was carried out in the Physical Therapy and Rehabilitation Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from May, 2017 to the same month in 2019. With this purpose the most frequent risk factors of coronary disorders were selected in the sample, which were analyzed before and after the implementation of the program. Results: Risk factors prevailed in men (68.4 %), with a higher incidence of hypertriglyceridemia in both sexes (56.1 %). After the rehabilitation, a decrease of glycemia, triglycerides and serum cholesterol figures was achieved. Conclusions: The programs of cardiovascular rehabilitation improve the health of the patients and provide as well socioeconomic benefits to the society.

ABSTRACT

Kawasaki disease is the main cause of acquired heart disease in children. The cardiovascular sequelae of Kawasaki disease, such as coronary artery lesion and giant coronary aneurysm, have a great impact on children's physical and mental health. The Japanese Circulatory Society and the Japanese Society of Cardiac Surgery jointly released the JCS/JSCS 2020 guideline on diagnosis and management of cardiovascular sequelae in Kawasaki disease in July, 2020, which systematically introduces the advances in the diagnosis and management of cardiovascular sequelae of Kawasaki disease. The article gives an interpretation in the severity evaluation of Kawasaki disease and diagnosis, treatment and long-term management of cardiovascular sequelae in the guideline.

ABSTRACT

De Winter syndrome,a special electrocardiogram of acute total occlusion or subtotal occlusion of left anterior descending coronary artery,is not common in clinical practice.It has been generally considered static,whereas the electrocardiogram changes dynamically in this case.We propose that de Winter pattern may indicate a thrombotic disease and can be roughly divided into two types according to whether the electrocardiogram changes dynamically.

ABSTRACT

This study aimed to examine and summarize clinical characteristics of Kawasaki disease (KD) at different ages to further strengthen clinicians understanding of children with KD, improving the level of diagnosis, and reducing coronary artery complications of KD. A total of 398 patients with KD who were diagnosed between January 2016 and December 2017 were reviewed retrospectively. These participants were allocated into three groups according to age: group A (<1 year, n=62), group B (≥1 and <5 years, n=286), and group C (≥5 years, n=50). Clinical manifestations, laboratory results, and echocardiographic findings were compared among the groups. Most (71.86%) patients with KD were aged 1-5 years. The prevalence of cervical lymphadenopathy was lowest in group A. The duration of fever before admission was longest in group A. The rate of cervical lymphadenopathy and laboratory data were different among the groups. Group A had higher frequencies of gastrointestinal involvement, neurological symptoms, and redness at the Bacillus Calmette-Guerin inoculation site than the other groups. Infants aged <1 year with KD often have a longer duration of fever before admission, a lower prevalence of cervical lymphadenopathy, and a higher prevalence of gastrointestinal and neurological symptoms.

ABSTRACT

Dietary factors may influence the process of atherosclerosis and coronary artery calcification (CAC). This study assessed CAC and its association with dietary intake in asymptomatic men. We evaluated 150 asymptomatic men with mean age of 58.2±5.3 years. The dietary intake was assessed by the Food Consumption Register method. CAC was measured through multidetector computed tomography (MDCT) and assessed in accordance with the Agatston score. Modified Poisson regression model was used to estimate the effects of intake of different nutrients that are prevalent in moderate/severe CAC, adjusted for calorie intake and CAC risk factors by means of prevalence ratios and 95% confidence intervals [95%CI]. An association was found between the intake of some nutrients and moderate/severe CAC. Lower carbohydrate intake (P=0.021) and higher lipid intake (P=0.006) were associated with moderate/severe CAC. After adjustment, the nutrients associated with the prevalence of moderate/severe CAC were carbohydrates (P=0.040), lipids (P=0.005), and saturated fatty acids (SFA) (P=0.013). A 1% increase in lipids and SFA intake caused an increase of 4% [95%CI: 1-7%] and 8% [95%CI: 2-14%] in the prevalence of moderate/severe CAC, respectively. A 1% increase of carbohydrate intake led to a 2% decrease in the likelihood of moderate/severe CAC [95%CI: 1-4%]. These conclusions showed that the higher intake of total lipids and SFA was associated with higher CAC scores, whereas higher carbohydrate intake was associated with lower CAC scores in asymptomatic men.

ABSTRACT

ABSTRACT Sophisticated imaging systems have helped to redefine the clinical presentation of acute macular neuroretinopathy and have markedly enhanced diagnostic sensitivity. The proposed mechanism of paracentral acute middle maculopathy is related to ischemia at the level of the superficial and deep retinal capillary plexi. This is a case report of a patient who developed an acute macular neuroretinopathy after an uneventful angioplasty with stents in the coronary artery.


RESUMO Sistemas de imagem sofisticados ajudaram a redefinir a apresentação clínica da neurorretinopatia macular aguda e têm sensibilidade diagnóstica marcadamente aumentada. A maculopatia média aguda paracentral tem sido relacionada à isquemia ao nível dos plexos capilares superficial e profundo da retina. Este é um relato de caso de paciente que desenvolveu uma neurorretinopatia macular aguda após uma cirurgia de angioplastia com stents da artéria coronária sem complicações.

ABSTRACT

A fístula de artéria coronária (CAF) é uma condição rara que envolve uma comunicação anormal entre uma artéria coronária e uma câmara cardíaca ou a outro vaso sanguíneo. A maioria das CAF são pequenas e raramente levam a sintomas. Contudo, a depender do seu local de origem e desembocadura, a CAF pode funcionar como um shunt esquerdo-direito do coração, levando a repercussões graves, como sobrecarga de volume do ventrículo direito, hipertensão pulmonar e "síndrome do roubo". No presente trabalho foi relatado o caso de um paciente assintomático com fístula de artéria coronária direita para ventrículo direito que apresentou alteração eletrocardiográfica


Coronary artery fistula (CAF) is a rare condition that involves abnormal communication between a coronary artery and a cardiac chamber or other blood vessel. Most CAFs are small and lead to symptoms. However, depending on its place of origin and outlet, a CAF can function as a left-right heart shunt, leading to serious repercussions, such as volume overload of the right ventricle, pulmonary hypertension and "theft syndrome". In the present study, the case of an asymptomatic patient with a right coronary artery fistula for the right ventricle who presented an electrocardiographic alteration

ABSTRACT

Kawasaki disease (KD) is a self-limiting, acute febrile vasculitis with predilection for children under-5 years. Most reports have emanated from Japan with only a few cases reported in Africa. KD presents a diagnostic dilemma and a high index of suspicion is critical as early treatment reduces the incidence of complications. We describe a 5-month-old male infant who presented with classical clinical features though with delayed diagnosis. Received moderate dose aspirin with limitation of access to intravenous immunoglobulin and who did not develop coronary artery complication. The case report highlights the diagnostic challenges faced by practitioners, made worse by the low index of suspicion inherent in our setting. The fatal complications that may be associated with KD can, therefore, be avoided. It is hoped that pediatricians in particular would become conversant with the diagnostic criteria to facilitate early diagnosis and intervention in children

ABSTRACT

Abstract Objective: To investigate the correlation between cardiac output values and renal neutrophil gelatinase-associated lipocalin (NGAL) levels as a biomarker of renal ischemia. Methods: Forty patients, who underwent off-pump coronary artery bypass (OPCAB) surgery and in whom the positioning of the heart was fixed with simple suspension sutures without a mechanical stabilizer, were included in the study. Continuous cardiac output (CO) measurements were recorded using the arterial pressure waveform analysis method (FloTrac sensor system) in the perioperative period. CO was recorded every minute during non-anatomical cardiac positioning for left anterior descending artery (LAD), diagonal artery (D), circumflex artery (Cx), and right coronary artery (RCA) bypasses. Serum NGAL samples were analyzed in the preoperative, perioperative, and postoperative periods. Results: The CO values measured at various non-anatomical cardiac positions during distal anastomosis for LAD, D, Cx, and RCA were significantly lower than pre- and postoperative values measured with the heart in normal anatomical position (3.45±0.78, 2.9±0.71, 3.11±0.56, 3.19±0.81, 5.03±1.4, and 4.85±0.78, respectively, P=0.008). There was no significant difference between CO values measured at various non-anatomical cardiac positions during distal anastomosis. Although there was no significant correlation between NGAL levels and age, duration of surgery, preoperative CO, D-CO, RCA-CO, and postoperative CO measurements, there was a significant correlation between NGAL levels and LAD-CO (P=0.044) and Cx-CO (P=0.018) at the postoperative 12th hour. Conclusion: Full revascularization may be achieved by employing the OPCAB technique while using simple suspension sutures without a mechanical stabilizer and by providing safe CO levels and low risk of renal ischemia.

ABSTRACT

SUMMARY: Thorough knowledge and understanding of coronary arteries and their anatomy is essential when performing cardiac surgery such as a coronary bypass. Coronary angiography is a minimally invasive method used to evaluate the anatomy and obtain different measurements of the coronary arteries. This study was designed to evaluate the endoluminal diameter, trunk length and anatomical distribution of coronary arteries in Chilean subjects without apparent angiographic lesions. Measurements were carried out by 3 trained examiners using Leonardo® software program in 238 Chilean subjects of both sexes with an age-range of 45 to 78 years. Ostium and the distal luminal segments diameters were measured, as well as trunk length of both right and left coronary arteries. Ostium of the anterior interventricular artery, dominance and tortuosity were also registered. In the right coronary artery, the diameters (3.8 ± 1.2 mm and 3.6 ± 1.0 mm) differed according to sex and dominance, and the length (35.2 ± 12.5 mm) differed according to age. In the left coronary artery, the diameters (4.9 ± 1.1 mm and 4.7 ± 1.0 mm) were greater in males than in females. The left coronary artery showed greater diameters and length than the right coronary artery. The prevalence of right arterial dominance was 88.0 %. Patients with right arterial dominance presented greater distal caliber in the right coronary artery than those with left arterial dominance (p<0.05), especially in older patients. Significant arterial tortuosity was observed in seven subjects.


RESUMEN: Un factor clave durante los procedimientos quirúrgicos cardiacos tal como el bypass coronario, es el conocimiento exhaustivo de las arterias coronarias y su anatomía. La angiografía coronaria es un método mínimamente invasivo que se utiliza para evaluar la anatomía y obtener diferentes medidas. El presente estudio fue diseñado para evaluar el diámetro endoluminal, la longitud del tronco y la distribución anatómica de las arterias coronarias en sujetos chilenos sin lesiones angiográficas significativas. Las mediciones fueron realizadas en 238 sujetos chilenos de ambos sexos con un rango etario entre 45 a 78 años. Tres examinadores preparados llevaron a cabo las mediciones utilizando el software Leonardo®. Se midieron los ostios y los diámetros luminales distales de los troncos coronarios derecho e izquierdo, como también las longitudes del tronco de las arterias coronarias derecha e izquierda. Además, se identificaron los ostios de la arteria interventricular anterior, dominancia y tortuosidad. En la arteria coronaria derecha, los diámetros (3,8 ± 1,2 mm y 3,6 ± 1,0 mm) se observaron variaciones según el sexo y la dominancia, y la longitud (35,2 ± 12,5 mm) difirió según la edad. En la arteria coronaria izquierda, los diámetros (4,9 ± 1,1 mm y 4,7 ± 1,0 mm) fueron mayores en los hombres que en las mujeres. La arteria coronaria izquierda mostró mayor diámetro y longitud que la arteria coronaria derecha. La prevalencia de dominancia arterial derecha fue del 88,0 %. Los pacientes con dominancia arterial derecha presentaron mayor calibre distal en la arteria coronaria derecha que aquellos con dominancia arterial izquierda (p <0,05), especialmente en pacientes mayores. En siete sujetos se observó una tortuosidad arterial significativa.

ABSTRACT

Resumen Objetivo: Encontrar una relación entre los niveles de proteína C reactiva (PCR) y fibrinógeno, y la extensión de la aterosclerosis en el síndrome coronario agudo. Métodos: Estudio observacional prospectivo, en el que se incluyeron 873 pacientes con síndrome coronario atendidos en un hospital entre 2016 y 2018. Se analizaron niveles de PCR y fibrinógeno, marcadores metabólicos y extensión de la aterosclerosis coronaria. Resultados: No se halló correlación positiva entre los niveles de PCR y fibrinógeno y los marcadores metabólicos, así como tampoco con enfermedad de uno, dos y tres vasos (p 0,829; p 0,810). Conclusiones: Los niveles sanguíneos de PCR y fibrinógeno se relacionan con la tasa de eventos cardiovasculares, pero no se ha podido demostrar que exista relación entre estos y la severidad de la aterosclerosis coronaria.


Abstract Objective: To determine whether there is a relationship between C - reactive protein and fibrinogen levels and the extent of atherosclerosis in acute coronary syndrome. Methods: A prospective observational study was conducted that include 873 patients with coronary syndrome treated in a hospital between the years 2016 and 2018. An analysis was made that included C - reactive protein and fibrinogen levels, metabolic markers, extent of coronary atherosclerosis. Results: No positive correlation was found between the C - reactive protein and fibrinogen levels and the metabolic markers, nor with one, two, or three vessel disease (P=.829; P=.810). Conclusions: Although blood C-Reactive Protein and fibrinogen levels are associated with the rate of cardiovascular events, this study was unable to demonstrate whether there is a relationship between these and the severity of the coronary atherosclerosis.

ABSTRACT

Resumen La enfermedad aneurismática coronaria se define como la dilatación de un segmento arterial coronario más 1,5 veces el diámetro de las arterias adyacentes de tamaño normal. Puede ser difusa, y afectar todo el trayecto de la arteria, o localizada y afectar sólo un segmento arterial específico. Puede encontrarse entre un 3 a un 8% de los estudios angiográficos y entre un 0,22% a un 1,4% de las necropsias clínicas. Se presenta 3 reportes de casos, donde la presentación clínica, los hallazgos angiográficos y el manejo farmacológico es diverso como corresponde a esta entidad.


Abstract Coronary aneurysm disease is defined as the dilation of a coronary artery segment more than 1.5 times the diameter of the adjacent arteries of normal size. It may be diffuse, and affect the whole trajectory of the artery, or localised and only affect a specific arterial segment. It can be found in between 3% and 8% of angiograph studies, with between 0.22% and 1.4% in clinical post-mortems. Three case reports are presented in which the clinical presentation, the angiographic findings, and the pharmacological management are shown to be as diverse as this condition itself.
