Sars-COV2 usually has a flu-like condition with possible progression to lung involvement. Isolated cardiac involvement has a slight frequency and present as arrhythmias, pericarditis or myocarditis.This is a rare case of COVID-1 patient, without pulmonary involvement with pericarditis, pericardial effusion and focal left ventricular impaired contraction.
Hypertrophic cardiomyopathy is unique and presents with myriad of clinical symptoms and signs affecting infants to the very old [1,4,5]. Most of the affected individuals probably have an uneventful life. However, in some patients with HCM the disease results in profound clinical implications including
Left atrial (LA) dilation is a common indicator of diastolic dysfunction, and its analysis through a volume calculation reflects the cumulative effects of the left ventricular (LV) filling pressures. However, an increase in LA volume is not exclusive to diastolic dysfunction, which has also been observed in other clinical conditions. Thus, the evaluation of the LA strain enables a functional study of this chamber, adding to the morphological analysis through the volume calculation.The LA strain, measured using the speckle tracking technique, brings information on the reservoir, conduction, and contractile functions of the LA, and is related to the LV function. Moreover, the changes in the LA strain precede the volumetric changes by nearly a decade, and correlate inversely with the degree of LA fibrosisthis has an important relationship with the diastolic dysfunction and its grading system. Albeit insufficient to explain its totality, LA fibrosis can partially justify the functional changes of this heart chamber and can favor the use of this variable as a complement to the current protocols for the analysis of the diastolic function.Although further study is still warranted to establish other clinical applications, the LA strain stands out in the analysis of diastolic dysfunction and can be considered ready to use, offering a great potential to improve the evaluation of the overall cardiac function.
Introdução: A avaliação de congestão pulmonar ambulatorial em pacientes com insuficiência cardíaca com fração de ejeção reduzida (ICFER) pode minimizar internações por descompensação e otimizar o uso de diuréticos.
Objetivo: Comparar o dispositivo dielétrico remoto (DDR), equipamento validado para detectar líquido extravascular pulmonar, com parâmetros clínicos, medidas de ecocardiograma transtorácico (ETT) e ultrassom de pulmão (ULSP).
Métodos: Incluímos 38 pacientes do ambulatório de miocardiopatias (63±12 anos; 21 homens). Todos foram submetidos, num período de 24 horas, à avaliação clínica com descrição de dispneia paroxística noturna, edema de membros inferiores (EMI), presença de tonturas; avaliação laboratorial de NT-ProBNP; avaliação pelo DDR e ETT com análise de parâmetros de congestão sistêmica pela veia cava inferior, função do ventrículo direito e de congestão pulmonar, como a avaliação das pressões de enchimento por meio E/e’ médio e volume indexado do átrio esquerdo.
O ULSP foi realizado com o protocolo de 8 quadrantes anteriores, com contagem de linhas B em um ciclo respiratório.
Resultados: 22 pacientes apresentavam DDR ≥ 35% (congestão pulmonar) e 16 pacientes DDR < 35%. Parâmetros clínicos e ecocardiográficos foram comparados com o DDR ≥ 35%. Na análise multivariada, as variáveis superfície corpórea (SC), linhas B e EMI se associaram a DDR ≥ 35%. NT-ProBNP foi semelhante e elevado em ambos os grupos.
Conclusões: O acompanhamento ambulatorial de ICFER para controle volêmico pode ser sensibilizado pela presença de linhas B no ULSP, que apresenta boa correlação com DDR ≥ 35%. NT-ProBNP não foi capaz de diferenciar pacientes com maior grau de congestão detectado pelo DDR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
