ABSTRACT

ABSTRACT BACKGROUND: Coronary artery disease is an important cause of morbidity and mortality. The impact of ventricular arrhythmias with impaired cardiac vagal activity is one of the most recently studied prognostic factors. However, there are no studies evaluating the phenomenon of heart rate turbulence (HRT) during physical exertion. OBJECTIVE: To study the behavior of HRT during exercise testing, among individuals after myocardial infarction. DESIGN AND SETTING: Feasibility study conducted in a university hospital among individuals 4-6 weeks after myocardial infarction. METHODS: All subjects underwent 24-hour Holter monitoring and ergometric stress testing. We considered that abnormal HRT was present if the turbulence onset was ≥ 0% or turbulence slope was ≤ 2.5 mm/relative risk interval. RESULTS: All 32 subjects were asymptomatic. Their median age was 58 years (interquartile range 12.8) and 70% were male. Abnormal HRT was associated with ventricular dysfunction in this population. We found no differences regarding the behavior of HRT, in relation to age, gender, smoking, systemic arterial hypertension, diabetes mellitus or dyslipidemia. Ergometric stress testing detected premature ventricular beats (PVB) in approximately 44% of the examinations, and these occurred both during the active phase of effort and in the recovery period. The low occurrence of several isolated PVB in beta-blocked subjects made it difficult to perform statistical analysis to correlate HRT between ergometric and Holter testing. CONCLUSION: The data obtained in this study do not support performing HRT through ergometric stress testing among patients who remain on beta-blockers post-myocardial infarction, for the purpose of assessing cardiac vagal activity.

ABSTRACT

SUMMARY OBJECTIVE: Premature ventricular contraction is generally known as benign in the absence of structural heart disease; however, premature ventricular contraction-induced left ventricular systolic dysfunction or ventricular arrhythmias are defined in some cases. Ventricular repolarization duration differs between myocardial cells, which causes myocardial electrical heterogeneity and is thought to be responsible for ventricular arrhythmias. In our study, we aimed to evaluate the association of ventricular repolarization parameters including Tp-Te interval, Tp-Te/QT ratio, and QRS-T angle with premature ventricular contraction frequency in patients with premature ventricular contraction burden. METHODS: A total of 80 subjects who were admitted to our cardiology department and underwent 24-h electrocardiography Holter monitoring were included. Patients were divided into two groups: group 1 is defined as premature ventricular contraction burden that had frequent premature ventricular contraction ≥1% in 24-h Holter monitoring, and group 2 is defined as rare premature ventricular contraction <1% in 24-h Holter monitoring. RESULTS: Tp-Te interval and Tp-Te/QT ratio are statistically significantly prolonged in the premature ventricular contraction burden group than in the control group (85.3±13.9 vs. 65.7±11.9, p<0.001; 0.19±0.03 vs. 0.15±0.02, p<0.001, respectively). QRS-T angle was statistically significantly abnormal in the premature ventricular contraction burden group (p=0.024). CONCLUSION: Increased Tp-Te interval and widened QRS-T angle are associated with ventricular arrhythmias and might be used for the prediction of premature ventricular contraction burden in patients with premature ventricular contraction in electrocardiography in the absence of 24-h Holter monitoring.

ABSTRACT

Abstract Background Chronic Hepatitis C (CHC) therapy with direct-acting antivirals (DAAs) has high efficacy and safety, but some cases of bradyarrhythmias have been described. Objective To evaluate heart rhythm disorders during DAA treatments. Methods Forty-eight patients with CHC (mean 61 years of age; 56% males; 73% HCV genotype 1) were evaluated before and during treatment with DAAs, analyzed by a resting 12-lead ECG [PR, QRS, and QT corrected (QTc) intervals measured] and a 24-h-Holter system, to evaluate the heart rate (HR) and the occurrence of arrhythmias. The Student's t-test or the Wilcoxon-Mann-Whitney test for continuous, independent variables were performed with a statistically significant p-value < 0.05. Results The electrocardiographic parameters before and during treatment were: PR interval (147.2 ± 15.6 vs 144.9 ± 15.6 ms; p = 0.21), QTc interval (427 ± 22.3 vs 421.7 ± 25.3 ms; p = 0.24), minimum HR (52.7 ± 8.4 vs 53.2 ± 8.5 bpm; p = 0.49), median HR (74.2 ± 10.4 vs 75.2 ± 9 bpm; p = 0.83), and maximum HR (117.4 ± 16.8 vs 117.9 ± 16.3 bpm; p = 0.25). These parameters proved to be similar among 11 beta-blockers or 22 ribavirin users. During treatment, the 21 cirrhotic patients presented significantly lower median HRs (72.1 ± 9.0 vs 77.9 ± 8.2 bpm; p = 0.02) and maximum HRs (108.9 ± 15.2 vs. 125.1 ± 13.2 bpm, p < 0.0001) through a 24-h-Holter monitoring than the patients without cirrhosis. No clinically relevant arrhythmias were detected. Conclusion DAAs do not significantly influence heart rate or induce significant cardiac arrhythmias in patients with CHC.

ABSTRACT

Resumo A fibrilação atrial (FA) é a arritmia cardíaca sustentada mais comum na população geral, tendo uma alta carga de morbimortalidade, e isso também é válido para pacientes com câncer. A associação entre FA e câncer vai ainda mais longe, com alguns estudos sugerindo que a FA pode ser um marcador de câncer oculto. Há, no entanto, uma notável escassez de dados sobre os desafios específicos do manejo da FA em pacientes com câncer. O reconhecimento e o manejo imediatos da FA nesta população especial podem diminuir a morbidade relacionada à arritmia e ter um importante benefício prognóstico. Esta revisão se concentrará nos desafios atuais de diagnóstico e manejo da FA em pacientes com câncer, com ênfase especial nas estratégias e dispositivos de rastreamento da FA e na terapia de anticoagulação com anticoagulantes orais não antagonistas da vitamina K (NOACs) para prevenção tromboembólica nesses pacientes. Alguns insights sobre as perspectivas futuras para a prevenção, diagnóstico e tratamento da FA nesta população especial também serão abordados.


Abstract Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in the general population, carrying a high morbimortality burden, and this also holds true in cancer patients. The association between AF and cancer goes even further, with some studies suggesting that AF can be a marker of occult cancer. There is, however, a remarkable paucity of data concerning specific challenges of AF management in cancer patients. AF prompt recognition and management in this special population can lessen the arrhythmia-related morbidity and have an important prognostic benefit. This review will focus on current AF diagnosis and management challenges in cancer patients, with special emphasis on AF screening strategies and devices, and anticoagulation therapy with non-vitamin K antagonist oral anti-coagulants (NOACs) for thromboembolic prevention in these patients. Some insights concerning future perspectives for AF prevention, diagnosis, and treatment in this special population will also be addressed.

ABSTRACT

Resumo Fundamento: A (-)-carvona é um monoterpeno encontrado em óleos essenciais com atividade antioxidante e anti-inflamátoria. Objetivos: O objetivo deste estudo foi analisar a propriedade antiarrítmica da (-)-carvona no coração de rato e seus efeitos sobre a sinalização de Ca+2 intracelular. Métodos: Os efeitos da (-)-carvona foram avaliados sobre a contratilidade atrial (0,01 - 4 mM) e ventricular (0,5 mM), e no eletrocardiograma (0,5mM). A fração de encurtamento, a corrente de cálcio do tipo L (ICa,L) e a sinalização de Ca+2 foram medidas no cardiomiócito isolado (0,5 mM). O efeito antiarrítmico foi avaliado no modelo de arritmia induzida por sobrecarga de cálcio (0,5 mM) (n = 5). Um p < 0,05 foi adotado como nível de significância estatística. Resultados: No átrio, a (-)-carvona causou inotropismo negativo de maneira concentração-dependente (EC50 0,44 ± 0,11 mM) e diminuiu o inotropismo positivo induzido pelo CaCl2 (0,1 - 8,0 mM) e BAY K8644 (5 - 500 nM), um agonista de canal de cálcio do tipo L. Em coração isolado, a (-)-carvona (0,5mM) reduziu a contratilidade ventricular em 73% e a frequência cardíaca (em 46%), aumentou o Pri (30,7%, tempo desde o início da onda P até a onda R) e o QTc (9,2%, uma medida de despolarização e repolarização dos ventrículos), sem mudar a duração do complexo QRS. A (-)-carvona diminuiu a fração de encurtamento (61%), a (ICa,L) (79%) e o transiente intracelular de Ca+2 (38%). Além disso, a (-)-carvona apresentou ação antiarrítmica, identificada pela redução do escore de arritmia (85%) e ocorrência de fibrilação ventricular. Conclusão: A (-)-carvona reduz a entrada de Ca+2 através de canais de Ca+2 do tipo L e, assim, diminui a contratilidade cardíaca e o Ca+2 intracelular e apresenta promissora atividade antiarrítmica no coração de ratos.


Abstract Background: (-)-Carvone is a monoterpene found in essential oils with antioxidant and anti-inflammatory activity. Objective: The aim of this paper was to analyze the antiarrhythmic property of (-)-carvone in the rat heart and its effects on the intracellular Ca2+ signaling. Methods: The effects of (-)-carvone were evaluated on the ventricular (0.5 mM) and atrial contractility (0.01 - 4 mM) and on electrocardiogram (0.5 mM). Fractional shortening, L-type calcium current (ICa,L) and Ca2+ signaling were measured in the isolated cardiomyocyte (0.5 mM). Antiarrhythmic effect was evaluated in arrhythmia model induced by calcium overload (0.5 mM) (n = 5). P < 0.05 was used as the significance level. Results: In the atrium, (-)-carvone evoked negative inotropism that was concentration-dependent (EC50 0.44 ± 0.11 mM) and decreased the positive inotropism evoked by CaCl2 (0.1 to 8.0 mM) or BAY K8644 (5 to 500 nM), an agonist of L-type Ca2+ channel. In isolated heart, (-)-carvone (0.5 mM) promoted reduction of ventricular contractility (73%) and heart rate (46%), increased PRi (30.7%, time from the onset of the P wave until the R wave) and QTc (9.2%, a measure of the depolarization and repolarization of the ventricles) without changing the QRS complex duration. (-)-Carvone decreased the fractional shortening (61%), ICa,L (79%) and Ca2+ intracellular transient (38%). Furthermore, (-)-carvone showed antiarrhythmic action, verified by decrease of the arrhythmia score (85%) and occurrence of ventricular fibrillation. Conclusion: (-)-Carvone decreases Ca2+ entry through L-type Ca2+ channels, reducing the cardiac contractility and intracellular Ca2+, and, therefore, presenting promising antiarrhythmic activity in the rat hearts.

ABSTRACT

La taquicardia supraventricular (TSV) es la principal taquiarritmia en el recién nacido (RN) que requiere una resolución urgente. Por su parte, la enterocolitis necrosante (ECN) es la emergencia gastrointestinal más común que afecta principalmente a RN prematuros. Aunque estas se reconocen como patologías distintas, la bibliografía sugiere que los episodios de TSV pueden predisponer a los pacientes a la ECN a través de alteraciones en el flujo sanguíneo mesentérico y una disminución de la perfusión tisular. Se presenta aquí el caso clínico de un neonato prematuro que desarrolló un cuadro de ECN luego de un evento aislado de TSV con bajo gasto cardíaco


Supraventricular tachycardia (SVT) is the main tachyarrhythmia in the newborn (NB) that requires urgent resolution. Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency that mainly affects premature infants. Although these conditions are recognized as distinct pathologies, literature reports suggest that episodes of SVT may predispose patients to NEC secondary to disturbances in mesenteric blood flow and a decrease in tissue perfusion. We present here the clinical case of a premature neonate who developed NEC after an isolated SVT event with low cardiac output

ABSTRACT

Los bloqueos auriculoventriculares son aberraciones cronotrópicas producidas por alteraciones de índole multifactorial en el sistema de inervación cardíaco. Específicamente se localizan entre las vías internodales que conducen el potencial de acción desde el nodo sinusal hasta el nodo auriculoventricular. Estos representan el 2,3% de las alteraciones cardíacas en la vida intrauterina, registrándose un caso por cada 20 000 a 25 000 nacidos vivos. Sin embargo, su ocurrencia en la infancia temprana y la edad escolar es desconocida. Asimismo, el porcentaje de causas idiopáticas de bloqueos auriculoventriculares en esta etapa de la vida es desconocido hasta el momento en Colombia. Dentro de las posibles etiologías se han documentado causas congénitas y adquiridas. Algunos ejemplos son casos aislados producto de isoinmunización materna, en hijo de madre lúpica o en coexistencia con alteraciones estructurales como anomalías del septo interventricular de índole neoplásico, defectos relacionados al ostium y la tabicación de las cámaras cardíacas. También se han descrito casos secundarios a infección por virus sincitial respiratorio y miocarditis vírica concomitante, incluyendo cardiomiopatías de origen inmune, reumático, infeccioso, tumoral, estructural, además de aquellas con compromiso mitocondrial en el cardiomiocito (síndrome de Kearns Sayre) con presentación más tardía con afectación multiorgánica. Todas ellas destacan por un fenómeno en común a nivel celular, referente a la inflamación crónica con reparación fibrótica en el sistema de conducción cardíaco, que conlleva alteraciones de la transmisión del potencial de acción y bradicardia con asíncrona auriculoventricular. También se han reportado causas idiopáticas descritas en el debut de una disautonomía primaria. Se presenta el caso de una paciente de 11 años con crisis de cefalea y síntomas vegetativos paroxísticos asociados a lipotimias a repetición, con posteriores estudios de extensión sin identificación de alteraciones estructurales ni hallazgos autoinmunes. A la niña se le diagnosticó bloqueo auriculoventricular completo, idiopático por lo que recibió manejo expectante por parte del servicio de electrofisiología.


Atrioventricular blocks are chronotropic abnormalities produced by multifactorial alterations in the cardiac innervation system, specifically between the internodal pathways between the sinus node and the atrioventricular node. These bradyarrhythmias represent 2.3% of cardiac alterations in intrauterine life, registering one case for every 20 000 to 25 000 live births. However, its occurrence in childhood and adolescence is unknown. Likewise, the percentage of idiopathic atrioventricular blocks in this group in Colombia is unknown to date. Among the possible etiol-ogies, congenital and acquired causes have been documented. Some examples are isolated cases found in pregnancies with maternal isoimmunization, from carriers with lupus, and in coexis-tence with structural alterations, such as anomalies of the interventricular septum due to cardiac tumors and defects in the ostium and septation of the cardiac chambers. Atrioventricular blocks are also associated with respiratory syncytial virus infection and concomitant viral myocarditis and with cardiomyopathies of immune, rheumatic, infectious, tumoral, and structural origin, in addition to mitochondrial diseases such as Kearns Sayre syndrome, presenting with multi- organ involvement. These etiologies lead to chronic inflammation with fibrotic repair in the cardiac conduction system, which alters the transmission of the action potential and bradycardia with atrioventricular asynchrony. Idiopathic causes described in the onset of primary dysautonomia have also been reported. We present the case of an 11- year- old patient with a headache crisis and paroxysmal vegetative symptoms associated with repeated fainting, with subsequent studies where no structural alterations or autoimmune findings were identified. The patient was diag-nosed with idiopathic complete atrioventricular block and received expectant management by the electrophysiology service.

ABSTRACT

Resumen Los complejos ventriculares prematuros (CVP) son hallazgos frecuentes en individuos con o sin enfermedad estructural cardiaca. Los CVP cuyo origen se localiza en la región parahisiana son poco frecuentes y su manejo a través de ablación con catéter de radiofrecuencia es un reto, pues su localización favorece un alto riesgo de desarrollo de bloqueo aurículo-ventricular. Se describen dos casos de pacientes con CVP parahisianos llevados a ablación con catéter de radiofrecuencia.


Abstract Premature ventricular complexes (PVC) are common findings in patients with or without structural heart disease. Parahisian PVC are uncommon and their management through radiofrequency catheter ablation remains a challenge, since their location favors a high risk for developing atrioventricular block. Two cases of patients with parahisian PVC undergoing radiofrequency catheter ablation are described.

ABSTRACT

Abstract Background: Current pacemakers allow for the continuous recording of the occurrence of arrhythmic events. One of the most frequent arrhythmias after implantation of a device is atrial fibrillation (AF), an important risk factor for embolic events. The frequency of this arrhythmia in pacemaker patients has not been widely studied. Objectives: This study aimed to evaluate the prevalence, incidence, and predictors of the occurrence of AF in patients with double-chamber pacemakers and without a history of atrial fibrillation prior to implantation. Methods: A dynamic, retrospective, and prospective cohort study was carried out with 186 patients undergoing biannual follow-up of the double-chamber pacemaker, without previous AF, in a single service, between 2016 and 2018. Clinical data were collected from the medical records and the telemetry of the device and the prevalence, incidence rate, relative risk by univariate analysis (by chi-square), and risk ratio were calculated by multivariate analysis (by Cox regression); values of p<0.05 were considered significant. Results: There was a prevalence of 25.3% FA, with an incidence of 5.64 cases / 100 persons-year. The median time for the development of arrhythmia was 27.5 months. Multivariate analysis identified 5 statistically significant predictors: male gender, OR: 2.54 [1.04-6.15]; coronary artery disease, OR: 2.98 [1.20-7.41]; hypothyroidism, OR: 3.63 [1.46-9.07]; prior heart surgery, OR: 2.67 [1.01-7]; and left atrial enlargement, OR: 2.72 [1.25-5.92]. Conclusions: The prevalence and incidence of AF in this population are high. Risk factors for AF were: male gender, coronary artery disease, hypothyroidism, prior heart surgery, and left atrial enlargement.

ABSTRACT

Resumen Introducción: La fibrilación auricular es la taquiarritmia sostenida más frecuente del ser humano y su manejo requiere un abordaje holístico para que los resultados sean óptimos. Objetivo: Describir las características sociodemográficas y clínicas de los pacientes hospitalizados o intervenidos, con diagnóstico de fibrilación auricular, atendidos en una clínica de cuarto nivel de complejidad en Colombia. Método: Se realizó un estudio observacional, retrospectivo, a partir de registros de pacientes hospitalizados o intervenidos con diagnóstico de fibrilación auricular. Se tomó como referencia el diagnóstico de fibrilación auricular (CIE 10 I48X), durante los años 2017 y 2018. Se realizó análisis univariado y bivariado con Excel, SPSS y Epidat. Resultados: El promedio de edad de los pacientes hospitalizados fue de 69.81 años, con ligera predominancia del sexo masculino. La estancia hospitalaria fue de 6.62 en 2017 y de 5.29 días en 2018. Se encontró correlación entre los días de estancia hospitalaria y la edad de los pacientes. La comorbilidad más frecuentes en los pacientes hospitalizados fue hipertensión arterial, cardiopatía isquémica y enfermedad pulmonar obstructiva crónica. El 18.04% no tuvieron comorbilidad. Las muertes intrahospitalarias estuvieron asociadas, con mayor frecuencia, a insuficiencia cardíaca. La cardioversión eléctrica fue el procedimiento electrofisiológico más usado, seguida del aislamiento de venas pulmonares. El porcentaje de complicaciones fue menor en 2018 que en 2017. Conclusiones: Existe menor proporción de comorbilidad cuando se compara esta serie con otros reportes. Los días de estancia hospitalaria fueron superiores a los encontrados en la literatura mundial.


Abstract Introduction: Atrial fibrillation is the most frequent sustained tachyarrhythmia in humans and its management requires an integral approach in order to get optimal results. Objective: To describe the sociodemographic and clinical characteristics of patients hospitalized or on surgical procedures with a diagnosis of atrial fibrillation, managed in a Fourth level of Complexity clinic in Colombia. Method: An observational, retrospective study was conducted from records of patients hospitalized or operated with a diagnosis of atrial fibrillation. The diagnosis of atrial fibrillation (ICD-10 I48X) was taken as a reference, during the years 2017 and 2018. Univariate and bivariate analysis was performed with Excel, SPSS and Epidat. Results: The average age of hospitalized patients was 69.81 years, with a slight predominance of males. The hospital stay was 6.62 and 5.29 days, during 2017 and 2018 respectively. Correlation was found between the days of hospital stay and the age of the patients. The most frequent comorbidities in hospitalized patients were arterial hypertension, ischemic heart disease and chronic obstructive pulmonary disease. 18.04 % of patients had no comorbidities. In-hospital deaths were more frequently associated with heart failure. Electrical cardioversion was the most frequent electrophysiological procedure followed by the isolation of pulmonary veins. The percentage of complications was lower in 2018 compared to 2017. Conclusions: There are a lower proportion of comorbidities when this series is compared with other reports. The days of hospital stay were superior to those found in the world literature.
