as taxas de quadros com STE são menores (50 a 90 quadros/seg) do que as taxas atingíveis com a imagem de deformação Doppler (≥100/seg), diminuindo potencialmente a precisão da avaliação dos parâmetros de tempo e levando à subestimação da deformação de pico
Os dados atuais sugerem que a ultrassômica pode melhorar a análise de textura na ecocardiografia quantitativa, descobrindo padrões imperceptíveis ao olho humano. Especificamente, este estudo investigou modelos de ML em nível de paciente e destacou o potencial da ultrassômica para caracterização do tecido miocárdico em pacientes com IM aguda.

🧠 Accompanying editorial by @bgrenne & Andreas Østvik (NTNU) calls this study a possible inflection point for echo: “… this body of work may mark the moment when echocardiography first challenged CMR for tissue characterization.” 🔥https://t.co/8zRE4lqvQ6
Carotid Doppler measurements in addition to IMT and plaque evaluation are independently associated with future CVEs in asymptomatic patients at risk for CAD.

Discussion Major findings To our knowledge, this is the first prospective study to investigate the relationship between carotid artery blood velocities (including EDV and PSV) and stroke and IHD. The results indicate that EDV and PSV were significant predictors of stroke and IHD, independent of traditional cardiovascular risk factors and IMT in the studied population, who were at low risk for atherosclerosis. Carotid flow velocities should be measured when evaluating the risk of stroke9 and IHD.
