ABSTRACT
Central Illustration : Position Statement on the Use of Myocardial Strain in Cardiology Routines by the Brazilian Society of Cardiology's Department Of Cardiovascular Imaging - 2023 Proposal for including strain in the integrated diastolic function assessment algorithm, adapted from Nagueh et al.67 Am: mitral A-wave duration; Ap: reverse pulmonary A-wave duration; DD: diastolic dysfunction; LA: left atrium; LASr: LA strain reserve; LVGLS: left ventricular global longitudinal strain; TI: tricuspid insufficiency. Confirm concentric remodeling with LVGLS. In LVEF, mitral E wave deceleration time < 160 ms and pulmonary S-wave < D-wave are also parameters of increased filling pressure. This algorithm does not apply to patients with atrial fibrillation (AF), mitral annulus calcification, > mild mitral valve disease, left bundle branch block, paced rhythm, prosthetic valves, or severe primary pulmonary hypertension.
Figura Central : Posicionamento do Departamento de Imagem Cardiovascular da Sociedade Brasileira de Cardiologia sobre o Uso do Strain Miocárdico na Rotina do Cardiologista 2023 Proposta de inclusão do strain no algoritmo integrado de avaliação da função diastólica, adaptado e traduzido de Nagueh et al. 67 AE: átrio esquerdo; Ap: duração da onda A reversa pulmonar; Am: duração da onda A mitral; DD: disfunção diastólica; FEVEr: fração de ejeção do ventrículo esquerdo reduzida; IT: insuficiência tricúspide; SAEr: strain do AE de reservatório; SLGVE: strain longitudinal global do ventrículo esquerdo. Se remodelamento concêntrico, confirmar com SLGVE. Na presença de FEVEr, tempo de desaceleração da onda E mitral (TDE) < 160 ms e onda S < D pulmonar também são parâmetros de pressão de enchimento aumentada. Esse algoritmo não se aplica a pacientes com fibrilação atrial (FA), calcificação do anel mitral ou valvopatia mitral maior que discreta, bloqueio de ramo esquerdo (BRE), ritmo de marca-passo, próteses valvares ou hipertensão pulmonar (HP) primária grave.

Background: Patients with indeterminate form of Chagas disease/cardiac normality (ICD/CN) exhibited normal electrocardiograms and chest X-rays; however, more sophisticated tests detected some degree of morphological and functional changes in the heart. Objective: To assess the prevalence of systolic and diastolic dysfunction of the right ventricle (RV) in patients with ICD/CN. Methods: This was a case–control and prevalence study. Using Doppler two-dimensional echocardiography (2D), 92 patients were assessed and divided into two groups: group I (normal, n = 31) and group II (ICD/CN, n = 61). Results: The prevalence of RV systolic dysfunction in patients in groups I and II was as follows: fractional area change (0.0% versus 0.6%), mobility of the tricuspid annulus (0.0% versus 0.0%), and S-wave tissue Doppler (6.4% versus 26.0%, p = 0.016). The prevalence of global disorders such as the right myocardial performance index using tissue Doppler (16.1% versus 27.8%, p = 0.099) and pulsed Doppler (61.3% versus 68%, p = 0.141) and diastolic disorders such as abnormal relaxation (0.0% versus 6.0%), pseudonormal pattern (0.0% versus 0.0%), and restrictive pattern (0.0% versus 0.0%) was not statistically different between groups. Conclusion: The prevalence of RV systolic dysfunction was estimated to be 26% (S wave velocity compared with other variables), suggesting incipient changes in RV systolic function in the ICD/CN group. .
Fundamento: Pacientes com forma indeterminada da doença de Chagas/normalidade cardíaca (FIDC/NC) apresentam eletrocardiograma e raios X de tórax normais, porém, quando submetidos a exames mais sofisticados, são detectados alguns graus de alterações morfofuncionais do coração. Objetivo: Avaliar a prevalência de disfunção sistólica e diastólica do ventrículo direito (VD) em pacientes com FIDC/NC. Métodos: Estudo de caso-controle e prevalência. Foram avaliados 92 pacientes com Doppler ecocardiograma bidimensional (2D), divididos em dois grupos: grupo I (normal, n = 31) e grupo II (FIDC/NC, n = 61). Resultados: A prevalência da disfunção sistólica do VD em pacientes dos grupos I e II foi: mudança de área fracional (0,0% versus 0,6%), mobilidade do anel tricuspídeo (0,0% versus 0,0%) e onda S ao Doppler tecidual (6,4% versus 26,0%, com p = 0,016). As prevalências das disfunções globais – como índice de performance miocárdica direita ao Doppler tecidual (16,1% versus 27,8% com p = 0,099) e ao Doppler pulsado (61,3% versus 68% com p = 0,141) e diastólico, como alteração do relaxamento (0,0% versus 6,0%), padrão pseudonormal (0,0% versus 0,0%) e padrão restritivo (0,0% versus 0,0%) – não apresentaram significância estatística entre os grupos. Conclusão: A prevalência de disfunção sistólica do VD foi estimada em 26% (velocidade da onda S em comparação a outras variáveis), sugerindo alterações incipientes da função sistólica do VD no grupo FIDC/NC. .
