ABSTRACT

Resumo Fundamento A cardiomiopatia hipertrófica (CMH) e a doença de Fabry (DF) são doenças herdadas geneticamente com características fenotípicas de hipertrofia ventricular esquerda (HVE) que causam resultados cardíacos adversos. Objetivos Investigar as diferenças demográficas, clínicas, bioquímicas, eletrocardiográficas (ECG) e ecocardiográficas (ECO) entre CMH e DF. Métodos 60 pacientes com CMH e 40 pacientes com DF foram analisados retrospectivamente como uma subanálise do "estudo LVH-TR" após exclusão de pacientes com fibrilação atrial, ritmo de estimulação, bloqueios de ramo e bloqueios atrioventriculares (AV) de segundo e terceiro graus. O nível de significância foi aceito como <0,05. Resultados O sexo masculino (p=0,048) e a creatinina (p=0,010) são significativamente maiores a favor da DF; entretanto, infradesnivelamento do segmento ST (p=0,028), duração do QT (p=0,041), espessura do septo interventricular (SIVd) (p=0,003), espessura da parede posterior (PWd) (p=0,009), insuficiência mitral moderada a grave (IM) (p=0,013) e o índice de massa ventricular esquerda (IMVE) (p=0,041) são significativamente maiores a favor da CMH nas análises univariadas. Na análise multivariada, a significância estatística apenas permanece na creatinina (p=0,018) e na duração do intervalo QT (0,045). A DF foi positivamente correlacionada com a creatinina (rho=0,287, p=0,004) e a CMH foi positivamente correlacionada com o PWd (rho=0,306, p=0,002), IVSd (rho=0,395, p<0,001), IM moderada-grave (rho= 0,276, p<0,005), IMVE (rho=0,300, p=0,002), espessura relativa da parede (ERP) (rho=0,271, p=0,006), duração do QT (rho=0,213, p=0,034) e depressão do segmento ST (rho =0,222, p=0,026). Conclusão Características bioquímicas, ECG e ECO específicas podem auxiliar na diferenciação e no diagnóstico precoce da CMH e da DF.


Abstract Background Hypertrophic cardiomyopathy (HCM) and Fabry disease (FD) are genetically inherited diseases with left ventricular hypertrophy (LVH) phenotype characteristics that cause adverse cardiac outcomes. Objectives To investigate the demographic, clinical, biochemical, electrocardiographic (ECG), and echocardiographic (ECHO) differences between HCM and FD. Methods 60 HCM and 40 FD patients were analyzed retrospectively as a subanalysis of the 'LVH-TR study' after excluding patients with atrial fibrillation, pace rhythm, bundle branch blocks, and second and third-degree atrioventricular (AV) blocks. The significance level was accepted as <0.05. Results Male gender (p=0.048) and creatinine (p=0.010) are significantly higher in favor of FD; however, ST depression (p=0.028), QT duration (p=0.041), interventricular septum thickness (IVSd) (p=0.003), posterior wall thickness (PWd) (p=0.009), moderate-severe mitral regurgitation (MR) (p=0.013), and LV mass index (LVMI) (p=0.041) are significantly higher in favor of HCM in the univariate analyses. In multivariate analysis, statistical significance only continues in creatinine (p=0.018) and QT duration (0.045). FD was positively correlated with creatinine (rho=0.287, p=0.004) and HCM was positively correlated with PWd (rho=0.306, p=0.002), IVSd (rho=0.395, p<0.001), moderate-severe MR (rho=0.276, p<0.005), LVMI (rho=0.300, p=0.002), relative wall thickness (RWT) (rho=0.271, p=0.006), QT duration (rho=0.213, p=0.034) and ST depression (rho=0.222, p=0.026). Conclusion Specific biochemical, ECG, and ECHO characteristics can aid in the differentiation and early diagnosis of HCM and FD.

ABSTRACT

Antecedentes: La ECA2 ha mostrado ser un regulador esencial de la funcionalidad cardíaca. En un modelo experimental de insuficiencia cardíaca (IC) con Fier, modelo de coartación de aorta (COA), se encontró activación de la vía Rho-kinasa. La inhibición de esta vía con fasudil no mejoró el remodelado cardíaco ni la disfunción sistólica. Se desconoce en este modelo, si el deterioro de la función cardíaca y activación de la vía rho-kinasa se asocia con una disminución de la ECA2 cardíaca y si la inhibición de Rho-kinasa tiene un efecto sobre la expresión de ECA2. Objetivo: Nuestro objetivo es determinar si en la falla cardaca experimental por coartación aórtica, los niveles proteicos de ECA2 en el miocardio se asocian a disfunción sistólica y cual es su interacción con la actividad de ROCK en el miocardio. Métodos: Ratones C57BL6J machos de 7-8 semanas se randomizaron en 3 grupos experimentales. Grupo COA por anudación de la aorta + vehículo; Grupo COA + Fasudil (100 mg/Kg día) por bomba osmótica desde la semana 5 post-cirugía; y grupo control o Sham. Se determinaron las dimensiones y función cardíaca por ecocardiografía. Posterior a la eutanasia, se determinaron los niveles de ECA2 del VI por Western-blot y actividad de la Rho-kinasa Resultados: En los grupos COA+vehículo y COA-FAS hubo deterioro de la función cardíaca, reflejada por la reducción de la FE (47,9 ± 1,53 y 45,5 ± 2,10, p < 0,05, respectivamente) versus SHAM (68,6 ± 1,19). Además, aumentaron las dimensiones cardíacas y hubo desarrollo de hipertrofia (0,53 ± 0,02 / 0,53 ± 0,01, p < 0,05) medida por aumento de la masa cardíaca relativa respecto del grupo SHAM (0,40 ± 0,01). En los grupos COA+vehículo y COA-FAS se encontró una disminución significativa del 35% en la expresión de ECA2 cardíaca respecto al grupo control. Conclusiones: La disfunción sistólica por coartación aórtica se asocia con aumento de la actividad de Rho-kinasa y significativa disminución de la expresión de ECA2. La inhibición de Rho-kinasa no mejoró el remodelado cardíaco, la disfunción sistólica y tampoco modificó los niveles de ECA2 cardíaca.


Background: ACE2 has been described as an essential regulator of cardiac function. In an experimental model of heart failure (HF) and heart failure reduced ejection fraction (HFrEF), the aortic coarctation (COA) model, activation of the Rho-kinase pathway of cardiac remodeling was found. Inhibition of this pathway did not improve cardiac remodeling or systolic ventricular dysfunction. It is unknown in this model whether the impairment of cardiac function and activation of the rho-kinase pathway is associated with a decrease in ACE2 and whether rho-kinase inhibition has an effect on ACE2 expression. Objective: To determine if in experimental heart failure due to aortic coarctation, ACE2 protein levels in the myocardium are associated with systolic dysfunction and what is its interaction with ROCK activity in the myocardium. Methods: Male C57BL6J mice aged 7-8 weeks were divided into 3 groups and anesthetized: One group underwent COA+ vehicle; A second group COA + Fasudil (100 mg/Kg/d) by osmotic pump from week 5 post-surgery and; the third group, control(SHAM). Echocardiograms were performed to determine cardiac dimensions and systolic function. Rats were then euthanized. Ventricular expression of ACE2, activity of the Rho-kinase pathway by MYPT-1 phosphorylation, relative cardiac mass, area and perimeter of cardiomyocytes were determined by Western blot. Results: In both COA+vehicle and COA+FAS groups there was deterioration of cardiac function, reflected in the reduction of EF (47.9 ± 1.53 and 45.5 ± 2.10, p < 0.05, respectively) versus the SHAM group (68.6 ± 1.19). In addition, cardiac dimensions and hypertrophy increased (0.53 ± 0.02 / 0.53 ± 0.01, p < 0.05) due to increased relative cardiac mass compared to the SHAM group (0.40 ± 0.01). In the COA+vehicle and COA+FAS groups a significant decrease of 35% in cardiac ACE2 expression was found compared to the control group. Conclusions: Systolic dysfunction due to aortic coarctation is associated with increased Rhokinase activity and a significant decrease in ACE2 expression. Rho-kinase inhibition did not improve cardiac remodeling, systolic dysfunction, nor did it change cardiac ACE2 levels.

ABSTRACT

La miocardiopatía hipertrófica (MCH) es la miocardiopatía hereditaria más frecuente, su principal expresión fenotípica consiste en hipertrofia ventricular izquierda (HVI) en ausencia de condiciones de carga que la justifiquen. Cuando existe una variante genética patogénica se denomina MCH sarcomérica. Los criterios diagnósticos más aceptados son HVI ≥ 15 mm en cualquier segmento o ≥ 13 en ciertas condiciones, criterios que tienen tres inconvenientes: 1) La HCM es una patología donde la HVI es evolutiva, existiendo otros elementos más precoces, pero menos precisos, como criptas, bandas musculares y alteraciones de la válvula mitral y músculos papilares; 2) Pacientes de baja estatura pueden no alcanzar estos umbrales; 3) La MCH apical no queda siempre bien representada usando estos grosores, requiriendo indexar por tamaño del paciente y/o considerar la HVI relativa (relación grosor apical / basal que no debe superar 1). Presentamos una serie de casos con genotipo confirmado para MCH que no cumplen los criterios de HVI aceptados para MCH y donde se debe individualizar el diagnóstico considerando los tres elementos señalados.


Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiac condition; its phenotypic expression consists of ventricular hypertrophy (LVH) unrelated to loading conditions. In patients with a genetic pathogenic variant, the condition is termed sarcomeric HCM. Current diagnostic criteria are based on absolute left ventricular thickness, requiring ≥15 mm in any segment or ≥13 mm in particular conditions. These criteria have three pitfalls: 1) HCM is an evolving disease where LVH occurs gradually, with other early -but less precisephenotypic expressions such as myocardial crypts, muscular bands, or mitral and papillary muscle alterations; 2) Patients with short stature tend to have less LVH and do not reach the proposed thickness threshold. 3) Apical HCM is not correctly addressed in this cut-off as the heart tapers from base to apex, warranting indexing wall thickness to body size and using relative LVH in the apex (ratio from apex/base, abnormal,>1). This small case series includes three patients with a pathogenic genetic variant for HCM that doesn't satisfy the current criteria of LVH. For its precise assessment, the aforementioned points must be considered.

ABSTRACT

Background and Objectives : Hypertension is a significant public health issue. Isolated Systolic Hypertension (ISH) was once considered to be a benign aspect among the aging population, but an association with an increased risk of Cardiovascular Disease is now known. ISH shows an increasing prevalence with increase in age. This study was undertaken to determine the incidence of ISH among adults in Eastern India. Methods : This study evaluated the adult population (aged 18-70 years) attending the NRS Medical College and Hospital, a Tertiary Care Center in East India. The clinical characteristics and echocardiographic findings were also evaluated. Results : A total of 800 patients met the inclusion criteria, of whom 75 (9.37%) had ISH. Blood Pressure increased with age. The most common echocardiographic change observed in ISH patients was increased Left Ventricular Mass Index (LVMI), while concentric Left Ventricular Hypertrophy (LVH) was more common in women than men with isolated Systolic Hypertension. The incidence of LVMI increased as the severity of ISH increased. Furthermore, patients with stage 3 ISH were nearly 4 times more likely to develop Proteinuria. Conclusion : The findings of this study are in line with previous studies evaluating the presence of ISH in the adult Indian population. There is need for effective population screening along with effective treatment for Blood Pressure to reduce morbidity and mortality. Primary prevention strategies may be the need of the hour in the Indian population which is at risk of cardiovascular Disease associated with Hypertension

ABSTRACT

ObjectiveTo clarify the value of the left ventricular longitudinal strain(LVLS)parameters in patients with cardiac amyloidosis (CA) and primary hypertension with left ventricular hypertrophy (HLVH). MethodsForty-one patients confirmed with CA were selected and assigned to CA with hypertension group (n =14) and pure CA group (n=27) based on the initial diagnosis with or without hypertension. Twenty patients with primary hypertension-induced left ventricular hypertrophy (HLVH group) and twenty healthy controls were also selected, matching for gender, age, and body surface area. Clinical data, conventional echocardiography parameters were collected and LVLS parameters were measured. Within-group variations were compared among the four groups, and pairwise comparisons were conducted between groups. The sensitivity and specificity of each parameter in predicting CA were judged by the receiver operator characteristic (ROC) curvy in CA and HLVH patients with left ventricular ejection fraction (LVEF) preserved. ResultsAmong the conventional echocardiography parameters, LVEF and left ventricular end-diastolic diameter (LVEDD) were lower in the CA with hypertension group and pure CA group compared with the higher values in the HLVH group and control group. Whereas, left ventricular posterior wall thickness (LVPWT), relative wall thickness (RWT), and average E/e' were higher in the two CA groups compared with the HLVH group (all P<0.05).Among the LVLS parameters, Global longitudinal strain (GLS) was the worst in the CA with hypertension group so as pure CA group, modest in the HLVH group, and highest in the control group. On the contrary, relative longitudinal strain and ejection fraction strain ratio (EFSR) were the highest in the CA with hypertension group so as to pure CA group, modest in the HLVH group, and lowest in the control group (all P<0.05). ROC analysis showed that when LVEF was preserved, the absolute value of GLS less than 14.35% and EFSR higher than 4.28 could effectively distinguish CA from HLVH (all AUCs>0.9,all P<0.05); meanwhile GLS showed high sensitivity(100%) and EFSR showed great specificity(95%). There were not statistically significance in any parameter between CA with hypertension group and pure CA group(all P>0.05). ConclusionWhether CA was complicated with hypertension or not, there were statistically significance among routine echocardiography and LVLS parameters compared with HLVH. In particular, GLS and EFSR are accurate in predicting CA in patients with myocardial hypertrophy and preserved LVEF.

ABSTRACT

Background: During the cardiac cycle with the effect on cardiac function, Echocardiographic wall motion abnormalities are kinetic alterations in the cardiac wall motion. It can be characterized as per their grades and their distribution pattern like segmental or global. It can be attributed to a coronary territory or follow a non-coronary distribution. Aim of the study: The aim of the study was to evaluate the patterns of echocardiographic wall motion abnormalities among hypertensive patients with electrocardiographic left ventricular hypertrophy.Material & Methods:This was prospective observational study which was conducted in the Department of Cardiology, Ibrahim Cardiac Hospital & Research Institute, Dhaka, Bangladesh from January 2020 to January 2021. In total 76 hypertensive patients with electrocardiographic left ventricular hypertrophy were included as the study subjects for this study. This study was approved by the ethical committee of the mentioned hospital. A predesigned questioner was used in data collection. All data were collected, processed and analyzed by using MS Office and SPSS version 23 programs as per necessity.Results:In this study, in analyzing the status of wall motion abnormalities (WMA) among the participants we observed that, 22% of the patients were with segmental wall motion abnormalities, 18% were with global dysfunction and 59% were fully free from any type of WMA. Among patients with global dysfunctions, 71% were with mild and 12% were with moderate-to-severe dysfunction whereas this ratio was 47:24 in segmental abnormality patients. On the other hand, in analyzing the severity and location of patients with segmental WMA we observed that 47%, 24%, 53%, 41%, 18%, 24%, 29%, 47%, 35%, 53% and 41% were with mild dysfunction, moderate-to-severe dysfunction, inferior wall dysfunction, antero-septal dysfunction, anterior wall dysfunction, lateral wall dysfunction, posterior wall dysfunction, posterior septal dysfunction, LV base dysfunction, LV mid-cavity dysfunction and LV apical dysfunction respectively.Conclusion:In this study, majority of the participants were found free from any type of wall motion abnormality. ‘Mild dysfunction’, inferior wall dysfunction, anterior wall dysfunction, lateral wall dysfunction, posterior septal dysfunction, LV base dysfunction, LV mid-cavity dysfunction and LV apical dysfunction are found as some more frequent dysfunctions among patients with WMA.

ABSTRACT

Antecedentes: la presencia de hipertrofia ventricular izquierda (HVI) es un marcador pronóstico y de severidad en condiciones de sobrecarga de presión. Se determina por masa ventricular (MV) aumentada en el ecocardiograma, debiéndose ajustar la MV por tamaño corporal en pediatría (normalización). Existen múltiples métodos de normalización, pero se desconoce si estos métodos son comparables. Objetivo: comparar distintos métodos de normalización de MV en sujetos con y sin sobrecarga de presión y evaluar el impacto del estado nutricional en el diagnóstico de HVI. Métodos: estudio de corte transversal en niños entre 5-18 años, divididos en 3 grupos: A) sin sobrecarga de presión (SSP), B) HTA (confirmado o sospecha), o C) Con cardiopatía obstructiva izquierda (CCOI, gradiente ≥25 mmHg). Se analizó antropometría, presión arterial y parámetros ecocardiográficos convencionales. Se determinó HVI por 4 mé-todos de normalización de MV: 1) Superficie corporal (SC) según sexo, 2) Talla2,7>51g/m2,7 3) Z-Score de Talla ≥ Z+2 y 4) Masa corporal magra ≥ Z+2. Se evaluó la concordancia de los métodos por grupo y según el diagnóstico nutricional. Resultados: se analizaron 1162 sujetos, 673(57,9%) hombres, edad 10,2 ± 3,2 años, 852(73,3%) SSP, 192(16,5%) con HTA y 118(10,2%) con CCOI. Un 38,6% presentaba malnutrición por exceso. Se observó diferencia entre los métodos para HVI en pacientes SSP y con CCOI(p=0,01), y en obesos con CCOI. La concordancia entre los métodos fue variable (rango de Kappa 0,38­0,71). Conclusiones: existe variabilidad y discrepancia entre los distintos métodos de normalización utilizados para definir HVI, influenciados por el estado nutricional.


Background: The presence of left ventricular hypertrophy (LVH) is both prognostic and severity marker in pressure overload conditions. It is determined by increased ventricular mass (MV) in the echocardiogram. MV must be adjusted for body size in pediatrics (normali-zation). There are multiple normalization methods, but it is unknown whether these methods are comparable. Objective: To compare different methods of MV normalization in subjects with and without pressure overload and to evaluate the impact of nutritional status on LVH diagnosis. Methods: Cross-sectional study in children aged 5-18 years, divided into 3 groups: A) without pressure overload (SSP), B) Systemic hypertension (confirmed or suspected), or C) Left obstructive heart disease (CCOI, gradient ≥ 25mmHg). Anthropometrics, blood pressure, and conventional echocardiographic parameters were analyzed. LVH was determined by 4 MV normalization methods: 1) Body surface area (BSA) adjusted by gender, 2) height2.7, 3) Z-Score height ≥ Z+2, and 4) lean body mass ≥ Z+2. The concordance of the methods was evaluated by group and according to the nutritional diagnosis. Results: 1162 subjects were analyzed, 673(57.9%) men, age 10.2 ± 3.2 years, 852(73.3%) SSP, 192(16.5%) with hypertension and 118(10.2%) with CCOI. 38.6% presented overnutrition. A difference was demonstrated between the methods for LVH diagnosis in patients with SSP and with CCOI (p=0.01), and in obese patients with CCOI. Agreement between methods was variable (Kappa range 0.38­0.71). Conclusions: There is variability and discrepancy between the different normalization methods used to define LVH, influenced by nutritional status.

ABSTRACT

Fundamento: A Hipertensão Arterial Sistêmica (HAS) acomete mais de 35% da população brasileira e tende a trazer repercussões cardíacas, entre elas a hipertrofia ventricular esquerda (HVE). O eletrocardiograma (ECG) é um exame indicado na investigação de possíveis repercussões cardiológicas em pacientes hipertensos, podendo apresentar alterações sugestivas de HVE. Objetivo: Avaliar sinais da presença de HVE em indivíduos hipertensos através do ECG e comparar com achados de ecocardiograma transtorácico (ETT). Método: Estudo transversal retrospectivo. Foram revisados prontuários eletrônicos de 159 pacientes (65,2±9,8 anos) diagnosticados com HAS, com e sem HVE ao ETT. Os resultados dos exames ECG e ETT foram comparados para avaliar a sensibilidade e especificidade do ECG em relação ao ETT. Nesta análise, foram utilizados os critérios de Sokolow-Lyon e Cornell no ECG e a relação de massa indexada do ventrículo esquerdo (VE) e espessura relativa de parede ao ETT, para avaliação do padrão geométrico do VE (PGV). Resultados: Identificamos 128 pacientes hipertensos com HVE e 31 sem alterações geométricas. A sensibilidade e especificidade para identificar HVE ao ECG foram de 31% e 90%, respectivamente, quando considerado o critério de Sokolow-Lyon conjuntamente com o critério de Cornell. Conclusão: A melhor análise de HVE ao ECG deve considerar a associação dos critérios de Sokolow-Lyon e Cornell. Apesar de apresentar uma sensibilidade menor que o ETT, o ECG possui alta especificidade e continua sendo uma alternativa importante inicial para o diagnóstico de HVE em indivíduos hipertensos


Introduction: Hipertension is a condition that affects more than 35% of the brazilian population and can lead to cardiac repercussions such as left ventricle hypertrophy (LVH). The electrocardiogram (ECG) is used in the investigation of possible cardiac repercussions in hypertensive patients, as it may indicate alterations that suggest LVH. Objective: To evaluate signs of LVH in hypertensive patients through ECG and comparing with findings from transthoracic echocardiogram (TTE). Methods: Transversal retrospective study. One hundred fifty nine electronic medical records of hypertensive patients (65,2 ± 9,8 years), with and without LVH at the TTE, were selected. Results of the ECG and TTE were compared to assess the sensitivity and specificity of the ECG in relation to TTE. Sokolow-Lyon and Cornell criteria were applied on ECG and left ventricular mass index and relative wall thickness on TTE to assess left ventricular geometry. Results: We identified 128 hypertensive patients with abnormal left ventricular geometry and 31 hypertensive patients without geometric abnormalities. The sensitivity and specificity for LVH on ECG were 31% and 90%, respectively, when considering both the Sokolow-Lyon and the Cornell criteria. Conclusion: the best way to evaluate LVH on the ECG is by using both Sokolow-yon and Cornell criteria. Despite having a lower sensitivity than TTE, ECG has high specificity and continues to be an important initial alternative to be used in the assessment of LVH in hypertensive patients

ABSTRACT

Background: An old proverb teaches us “Good things come to those who sweat.” Apart from its philosophical and metaphysical meaning, it is also true by words. Many previous studies also supported this view, but study in the rural part of Bengal in this field had hardly been undertaken before. Aim and Objectives: The objective of the study was to find any difference in cardiovascular parameters, for example, arterial blood pressure, heart rate; to compare the body mass index (BMI), skin fold thickness among athletes and non-athlete adult male volunteers; and also to identify any difference in resting electrocardiogram (ECG) patterns between those two groups. Materials and Methods: The present article is a scientific validation of this statement. In technical terms, this is an institutional ethics committee certified case-control study conducted in Burdwan and Birbhum districts of West Bengal with 75 non-athlete people and 75 athletes. Results: With the help of modern diagnostic tools and rigorous statistical methods, it was found that there are significant differences (P < 0.00001) between these two groups in terms of waist circumference, abdominal skin fold thickness, BMI, diastolic blood pressure (BP), and left ventricular hypertrophy by ECG. From existing medical knowledge-base, this finding can immediately be interpreted as having higher risk factors of coronary heart diseases for non-athlete people. Conclusion: Based on these findings, authors recommended that a sedentary lifestyle should be avoided to get rid of hypertension and obesity and stay away from fatal coronary heart diseases. Regular Physical activity and healthy diet can help us to live a long and disease-free life. This article speaks nothing new and surprising but confirms an age-old truth with modern scientific experiments, methods, and techniques which is a need of the hour.

ABSTRACT

Resumo Fundamento A cardiomiopatia hipertrófica (CMH) e a hipertrofia ventricular esquerda (HVE) secundária à hipertensão arterial sistêmica (HAS) podem estar associadas a anormalidades funcionais do átrio esquerdo (AE). Objetivos Caracterizar a mecânica do AE na CMH e na HAS e avaliar qualquer correlação com a extensão da fibrose ventricular esquerda medida por ressonância magnética cardíaca (RMC) em pacientes com CMH. Métodos A função longitudinal do AE derivada do ecocardiograma bidimensional com speckle tracking foi adquirida a partir de cortes apicais de 60 pacientes com CMH e 34 indivíduos controles, pareados por idade. Pacientes com CMH também foram submetidos à RMC, com medida da extensão do realce tardio por gadolínio. A associação com parâmetros de strain do AE foi analisada. Valores p < 0,05 foram definidos como estatisticamente significativos. Resultados A média da fração de ejeção do ventrículo esquerdo não foi diferente entre os grupos. A razão E/e' estava comprometida no grupo CMH e preservada no grupo controle. A mecânica do AE estava significativamente reduzida na CMH em comparação aos pacientes com HAS. O strain rate do AE nas fases de reservatório (SRrAE) e na fase contrátil (SRctAE) foram os melhores parâmetros de discriminação de CMH com uma área sob a curva (AUC) de 0,8, seguido do strain do AE na fase de reservatório (SrAE) (AUC 0,76). O SRrAE e o SRctAE apresentaram elevada especificidade (89% e 91%, respectivamente), e o SrAE apresentou sensibilidade de 80%. Um decréscimo de 2,79% no strain rate do AE na fase de condução (SRcdAE) foi preditor de um aumento de 1 cm na extensão do RT pelo gadolínio (r2=0,42, β 2,79, p=0,027). Conclusões O SRrAE e o SRctAE foram os melhores fatores de discriminação de HVE secundária à CMH. O SRcdAE foi preditor do grau de fibrose ventricular esquerda avaliada por RMC. Esses achados sugerem que a mecânica do AE pode ser um potencial preditor de gravidade de doença na CMH.


Abstract Background Hypertrophic cardiomyopathy (HCM) and left ventricular hypertrophy (LVH) secondary to systemic hypertension (HTN) may be associated with left atrial (LA) functional abnormalities. Objectives We aimed to characterize LA mechanics in HCM and HTN and determine any correlation with the extent of left ventricular (LV) fibrosis measured by cardiac magnetic resonance (CMR) in HCM patients. Methods Two-dimensional speckle tracking-derived longitudinal LA function was acquired from apical views in 60 HCM patients, 60 HTN patients, and 34 age-matched controls. HCM patients also underwent CMR, with measurement of late gadolinium enhancement (LGE) extension. Association with LA strain parameters was analyzed. Statistical significance was set at p<0.05. Results Mean LV ejection fraction was not different between the groups. The E/e' ratio was impaired in the HCM group and preserved in the control group. LA mechanics was significantly reduced in HCM, compared to the HTN group. LA strain rate in reservoir (LASRr) and in contractile (LASRct) phases were the best discriminators of HCM, with an area under the curve (AUC) of 0.8, followed by LA strain in reservoir phase (LASr) (AUC 0.76). LASRr and LASR-ct had high specificity (89% and 91%, respectively) and LASr had sensitivity of 80%. A decrease in 2.79% of LA strain rate in conduit phase (LASRcd) predicted an increase of 1cm in LGE extension (r2=0.42, β 2.79, p=0.027). Conclusions LASRr and LASRct were the best discriminators for LVH secondary to HCM. LASRcd predicted the degree of LV fibrosis assessed by CMR. These findings suggest that LA mechanics is a potential predictor of disease severity in HCM.

ABSTRACT

OBJECTIVE: Systemic hypertension remains an important risk factors for cardiovascular diseases and a major global public health problem. Left ventricular hypertrophy (LVH) is a recognized complication of hypertension and strongly predicts cardiovascular morbidity and mortality. In Nigeria, few studies evaluated the role of echocardiography in the diagnosis of LVHs among hypertensives. This study sets out to determine the prevalence of LVH among hypertensives as determined by echocardiography.MATERIAL AND METHODS: One hundred and seventy-eight hypertensives and eighty-nine age and sex-matched controls were recruited consecutively into the study. They all had echocardiography done to determine which among had LVH. The partition value for LVH for hypertensives was determined using the 97th percentile of the left ventricular mass for controls as a cutoff point. RESULTS:Echocardiographic determined the prevalence of LVH among hypertensives was 32.4%.CONCLUSION:The echocardiographic prevalence of LVH was 32.4% in the study population. This is a significant proportion among the study population considering the clinical impact of LVH among patients with hypertension.

ABSTRACT

Objective:To evaluate the clinical efficacy of Tianma Gouteng Decoction combined with amlodipine besylate tabletsin treating patients with hypertension of liver-yang hyperactivity complicated with left ventricular hypertrophy (LVH).Methods:A total of 80 patients with hypertension of liver-yang hyperactivity complicated with LVH, who met the inclusion criteria and were treated in the hospital between June 2019 and January 2021, were divided into two groups, with 40 in each group according to the random number table method. The control group was treated with amlodipine besylate tablets orally, and the observation group was treated with granules of Tianma Gouteng Decoction on the basis of the control group. Both groups were treated for 2 months. Before and after treatment, the TCM syndromes were scored and the office blood pressure was measured with sphygmomanometer, and color Doppler ultrasonic diagnostic apparatus was adopted to detect the interventricular septum thickness (IVST), left ventricular posterior wall thickness (PWT), left ventricular end diastolic diameter (LVDd) and left ventricular mass index (LVMI), and the levels of homocysteine (Hcy) and Cystatin C (Cys-C) were determined by ELISA and the level of uric acid (UA) was determined by fully automatic biochemical analyzer. The clinical efficacy was evaluated.Results:The total effective rate was 95.0% (38/40) in the observation group and that of the control group was 77.5% (31/40) ( χ2=5.17, P=0.023). After treatment, the scores of dizziness, headache, insomnia and dreaminess and vexation and forgetfulness and total score of the observation group were significantly lower than those in the control group ( t=10.06, 14.47, 15.47, 8.74, 14.50, all Ps<0.001), and the systolic blood pressure and diastolic blood pressure were significantly lower than those in the control group ( t=6.30, 8.79, P<0.001). The IVST [(9.36±1.32) mm vs. (11.23±1.07) mm, t=6.96], PWT [(8.89±1.14)mm vs. (10.03±1.02)mm, t=4.71], LVDd[(40.36±4.29) mm vs. (47.62±4.19) mm, t=7.66] and LVMI [(112.39±22.29) g/m 2vs. (148.26± 21.39) g/m 2, t=7.34] were significantly lower compared to the control group ( P<0.01). The levels of Hcy[(12.87±3.11) μmol/L vs. (19.85±3.67) μmol/L, t=9.18], UA [(276.29±19.56) μmol/L vs. (338.52±17.07) μmol/L, t=16.65] and Cys-C [(0.86±0.15) mg/L vs. (1.10±0.17) mg/L, t=6.70] were significantly lower than those in the control group ( P<0.01). Conclusion:The Tianma Gouteng Decoction can improve the clinical symptoms, control the blood pressure, relieve the left ventricular hypertrophy and improve the renal function of patients with hypertension of liver-yang hyperactivity complicated with LVH.

ABSTRACT

This study was designed to assess the clinical efficacy of oral blood-activating and stasis-removing Chinese patent medicines in treating hypertensive left ventricular hypertrophy(LVH) based on network Meta-analysis. The clinical randomized controlled trials(RCTs) concerning the treatment of hypertensive LVH with oral blood-activating and stasis-removing Chinese patent medicines were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, and Cochrane Library from their inception to September 2021. Two researchers independently completed the literature screening, data extraction, and quality evaluation. The data were then analyzed by RevMan 5.3, Stata 15.1, and ADDIS 1.16.8. Finally, a total of 31 RCTs were included, involving 3 001 patients and four oral blood-activating and stasis-removing Chinese patent medicines. In terms of the alleviation of heart damage, the Chinese patent medicines combined with conventional western medicine groups were superior to the conventional western medicine groups in lo-wering the left ventricular mass index(LVMI). There was no significant difference in LVMI, left ventricular ejection fraction(LVEF), or the ratio of early diastolic peak flow velocity to late diastolic peak flow velocity(E/A) between different Chinese patent medicines combined with conventional western medicine groups. Xinnao Shutong Capsules/Tablets combined with conventional western medicine had the best efficacy in reducing LVMI and elevating LVEF, while Xinkeshu Capsules/Tablets combined with conventional western medicine had the best effect in improving E/A. In the control of blood pressure, when all Chinese patent medicines except for Xinnao Shutong Capsules/Tablets were combined with conventional western medicine, the resulting systolic blood pressure(SBP) and diastolic blood pressure(DBP) were significantly lower than those in the conventional western medicine group. Xinkeshu Capsules/Tablets combined with conventional western medicine produced the best effect in reducing SBP and DBP, followed by Xinnao Shutong Capsules/Tablets. In terms of safety, no serious adverse reactions occurred in all trials. The four oral blood-activating and stasis-removing Chinese patent medicines included in this study exhibited obvious advantages in the treatment of hypertensive LVH when they were combined with conventional western medicine, with the best effects observed in the Xinnao Shutong Capsules/Tablets combined with conventional western medicine group. However, due to the limitation of the quantity and quality of the included articles, the conclusion of this study still needs to be verified by more high-quality, multi-center, and large-sample RCTs.

ABSTRACT

Resumo Fundamento: Em associação às estatinas, os inibidores da pró-proteína convertase subtilisina/kexina tipo 9 (PCSK9) demonstraram ser eficazes na redução de eventos cardiovasculares em pacientes de alto risco. Objetivo: Analisar a custo-efetividade da implementação de evolocumabe para pacientes com alto risco de eventos cardiovasculares no contexto do Sistema Único de Saúde (SUS) no Brasil. Métodos: Um modelo de Markov foi utilizado, baseando-se em uma amostra ambulatorial de pacientes com doença arterial coronariana. Os desfechos primários analisados foram infarto agudo do miocárdio, acidente vascular cerebral isquêmico (AVCi), revascularização do miocárdio e morte cardiovascular. O resultado foi expresso por meio da razão de custo-efetividade incremental (RCEI), considerando-se uma taxa de desconto de 5% ao ano, e uma análise de sensibilidade foi realizada, tendo em vista a imprecisão de valores. Resultados: Selecionaram-se 61 pacientes com risco cardiovascular estimado em 35% em 10 anos, se em uso de atorvastatina 80mg/dia, e em 22,75%, se adicionado o evolocumabe. O custo global por paciente no período de 10 anos foi de R$ 46.522,44 no grupo em monoterapia com atorvastatina versus R$ 236.141,85 na terapia combinada, com uma efetividade global de 0,54 e 0,73, respectivamente. Isso resultou em uma RCEI R$ 1.011.188,07 (R$ 864.498,95 a R$ 1.296.748,43) por desfecho cardiovascular evitado. Conclusões: Apesar de não existirem padrões nacionais para custo-efetividade, os dados encontrados sugerem que a estratégia de associação do evolocumabe à terapia com estatina não é, no momento, custo-efetiva.

ABSTRACT

Segundo a Diretriz Brasileira de Hipertensão Arterial 2020, hipertensão arterial (HA) é uma doença crônica não transmissível (DCNT) definida por níveis pressóricos, em que os benefícios do tratamento não medicamentoso e/ou medicamentoso superam os riscos; e a falta de tratamento evolui com lesão de órgão alvo, como a hipertrofia ventricular esquerda. Neste estudo avaliamos a literatura no tocante à acurácia dos critérios eletrocardiográficos para diagnóstico de hipertrofia ventricular esquerda (HVE) e por conta das diferenças entre homens e mulheres, isso constitui um grande desafio. Dentre os fatores que mais interferem no critério sensibilidade, destacam-se a massa cardíaca e o sexo, sendo a sensibilidade do ECG maior com o aumento da massa ventricular e no sexo masculino, segundo Colossimo e Povoa. No estudo de Gasperin, onde foram utilizados critérios de voltagem, observou-se que o critério de Cornell nas mulheres foi de maior sensibilidade, de 54,90%, com alta especificidade de 81,60%. Quando a sensibilidade do critério de Cornell foi comparada à de Sokolow-Lyon-Rappaport, o segundo em sensibilidade, foi de 41,18%; sem significância estatística entre os dois. A detecção precoce da HVE tem importância prognóstica, já discutida em vários trabalhos e seus critérios de validação, um constante desafio. Definir critérios específicos em mulheres torna-se necessário para maior acurácia diagnóstica e abordagem precoce para intervenções terapêuticas sejam medicamentosas ou não. Conclui-se que o critério eletrocardiográfico de Cornell foi o método com maior sensibilidade nas mulheres, nesta revisão. São necessários estudos com análises especificas para o sexo feminino, considerando suas diferenças anatômicas e antropométricas e possivelmente ajustadas à população brasileira. Torna-se uma limitação desta análise, a lacuna resultante do pequeno número de dados e poucos estudos publicados sobre o tema.


According to the Brazilian Guidelines on Hypertension 2020, hypertension (AH) is a chronic non-communicabledisease (NCD) defined by blood pressure levels, in which the benefits of non pharmacologic and/or pharmacologic therapy out weigh The risks; and lack of treatment evolves with target-organ damage such as left ventricular hypertrophy. In this study, we evaluated the literature regarding the accuracy of the electrocardiographic criteria for the diagnosis of left ventricular hypertrophy (LVH) and, due to the differences between men and women, this represents a great challenge. Among the factors that most interfere with the sensitivity criterion, cardiac mass and gender stand out, with ECG sensitivity being greater with the increase in ventricular mass and in males, according to Colossimo and Povoa. In the study by Gasperin, where voltage criteria were used, it was observed that the Cornell criterion in women was more sensitive, 54.90%, with a high specificity of 81.60%. When the sensitivity of the Cornell criterion was compared to theSokolow-Lyon-Rappaport criterion, the latter in sensitivity was 41.18%; with no statistical significance between the two. The early detection of LVH hás prognostic importance, already discussed in several works and its validation criteria, a Constant challenge. Defining specific criteria in women becomes necessary for greater diagnostic accuracy and a nearly approach to therapeutic interventions, whether drug-related or not. It is concluded that the Cornell electrocardiographic criterion was the method with the greatest sensitivity in women in this review. However, studies with specific analyzes for females are still needed, considering their anatomical and anthropometric differences and possibly adjusted to the Brazilian population. The gap resulting from the small amount of data and few published studies on the subject becomes a limitation of this analysis

ABSTRACT

ABSTRACT Background: The biomarker for left ventricular hypertrophy (LVH) in patients with essential hypertension (EH) remains an unmet clinical need. The microRNA-30 (miR-30) family has been associated with LVH in cellular and animal studies, but not in a clinical setting. Objective: The objective of the study was to investigate the clinical significance of circulating levels of miR-30 family as a biomarker for LVH in EH patients. Methods: A total of 239 EH patients and 239 healthy controls were enrolled in this study. Circulating levels of miR-30 family members, namely, miR-30a, miR-30b, miR-30c-1, miR-30c-2, miR-30d, and miR-30e, were evaluated using real-time polymerase chain reaction assays. Results: The circulating miR-30a, miR-30b, and miR-30e were significantly reduced in EH patients in contrast to controls. EH patients with LVH (EH-LVH) had substantially lower circulating miR-30b and miR-30e levels compared to EH patients without LVH (EH-nLVH). Moreover, the expression levels of miR-30b and miR-30e were positively related to LVMI, respectively. Receiver operating curve analysis showed that circulating miR-30e levels distinguished EH patients from controls, and EH-LVH from EH-nLVH patients. Logistic regression analysis identified the circulating miR-30e as a risk factor for LVH in EH patients. Conclusion: Circulating miR-30e level can be used as a biomarker in distinguishing EH-LVH from EH-nLVH. A further prospective study is warranted to validate this finding.
