From the Guidelines
Speckle Ana refers to a technique used in echocardiography, specifically speckle tracking echocardiography (STE), which analyzes the movement of speckles within the myocardium to assess myocardial deformation and function. This technique is used to evaluate the function of the heart, particularly in patients with nonischemic cardiomyopathy, and can detect subtle alterations in left ventricular systolic function, even in the absence of detectable acute graft rejection 1. The speckle tracking technique can compute peak left ventricular global longitudinal strain (GLS) by analyzing the movement of speckles in conventional apical views, providing a sensitive marker of myocardial dysfunction 1.
Key Points
- Speckle tracking echocardiography (STE) is a technique used to assess myocardial deformation and function.
- STE can detect subtle alterations in left ventricular systolic function, even in the absence of detectable acute graft rejection.
- The technique can compute peak left ventricular global longitudinal strain (GLS) by analyzing the movement of speckles in conventional apical views.
- A reduction of 10% to 15% in peak systolic global longitudinal strain by speckle-tracking echocardiography is a useful parameter to predict cardiotoxicity 1.
Clinical Applications
- STE can be used to evaluate the function of the heart in patients with nonischemic cardiomyopathy.
- The technique can confirm, quantify, and detect associated abnormalities and complications, as well as risk stratify patients.
- STE can also be used to monitor the effects of chemotherapy on cardiac function and detect early signs of cardiotoxicity 1.
From the Research
Definition of Speckle Ana
- There is no direct information available on the term "speckle Ana" in the provided study 2.
- The study focuses on microcytic anemia, its differential diagnosis, and management of iron deficiency anemia, but does not mention "speckle Ana" explicitly.
- It discusses the characteristics of microcytic anemia, such as small and hypochromic red blood cells, and the importance of iron stores in differentiating iron deficiency from other microcytic states.
- Without further context or information, it is unclear what "speckle Ana" refers to or how it relates to the topic of microcytic anemia or other medical conditions.
