How is myocardial tension assessed?

Currently, the assessment of myocardial tension is a fairly common job to help timely detect cardiovascular diseases. Echocardiography is one of the effective support tools for checking how the heart muscle is straining.

Cardiac muscle is a type of muscle that is a mixture of two types of muscle, skeletal muscle and smooth muscle. Cardiac muscle can be divided into three types: atrial, ventricular, and special conductive muscle fibers. The atrial and ventricular muscles contract like skeletal muscle, the atrial and ventricular muscles contract, and the special conductive fibers have weaker contractile capacity but are rhythmic and conduct impulses. in heart. Cardiac muscle has 4 basic physiological properties: excitability, conduction, cyclical inertness, rhythmicity
We all know we can't live if the heart stops beating. The beating of the heart is determined by the heart muscle. The heart muscle contracts in a uniform system with strong connections between the muscle fibers. During the contraction process, the heart muscle is responsible for pushing blood through the circulation. All these functional activities are only guaranteed to be stable when the myocardial tension is good. So what is good heart muscle tension?

Myocardial tension represents the functional state of the myocardium, as measured by the length between the two states of the myocardium. Specifically, the tension will be: (L1-l0)/L0. Where: L0 is the initial length, L1 is the length when changing states. To facilitate this assessment, nowadays it is common to use the help of echocardiography. There are many ultrasound methods available today, but most of today's techniques are carried out in the following steps:
Step 1: Select some basic cross-sections and then select images to put into the machine Step 2: Review the image qualified for evaluation Step 3: Mark some points: at mitral annulus, apex of heart Step 4: Endocardial border of ventricular chamber Step 5: Adjust ROI Step 6: Consider quality of “tracking” contour Step 7: If the “tracking” contour is not optimal, repeat steps 5 and 6. Early assessment of myocardial function status, knowing how myocardial tension is very important in cardiac diseases Cardiovascular diseases, especially diseases such as myocardial infarction, myocardial hypertrophy, dilated cardiomyopathy,... These diseases, if not detected in time, have the potential to lead to very serious complications, even death rates. The mortality rate is very high due to sudden cardiac death. Like most diseases in other systems, early detection of abnormalities will greatly improve the effectiveness of treatment and prevent unwanted complications.

Thus, echocardiography is very important that everyone should not ignore to have a healthy heart and protect health in the best way. Currently, Vinmec Da Nang deploys the vivid E95 echocardiogram using software to assess myocardial tension (Speckle tracking). In particular, to protect cardiovascular health in general and detect early signs of myocardial infarction and stroke, customers can sign up for the Cardiovascular Screening Package - Basic Cardiovascular Examination of National General Hospital. Vinmec economy. The examination package helps to detect cardiovascular problems at the earliest through tests and modern imaging methods. The package is for all ages, genders and is especially essential for people with risk factors for cardiovascular disease.
