Novel index for testing partial elasticity of artery

Abstract

The invention provides a novel index for testing the partial elasticity of the artery, belonging to the field of cardiovascular mechanics and having great significance to the related basic research and clinical work. At present, a variety of indexes are used for reflecting the elasticity of the whole blood vessel, but no index is available to reflect the partial elasticity of the blood vessel, and the basic research and the clinical work have an urgent need for a novel index for measuring the partial elasticity of the artery. The novel index provided by the invention fills the blank. The novel index is obtained by measuring the stress of the blood vessel wall on different parts and in different directions (circumferential direction and longitudinal direction) when the blood vessel wall is subjected to one blood-pressure change through deducing and calculating according to the Laplace's law and essentially reflects that the force (pulse pressure) needed by the partial blood vessel wall to generate a certain stress in a certain direction represents the elasticity of the partial blood vessel. The novel index can be also used for directly calculating the Young modulus of the partial blood vessel.

Description

Technical field [0001] The patent of the present invention relates to a new index that can reflect the local elasticity of arteries. Based on the new index proposed in this patent, the quantitative detection and evaluation of local arterial blood vessel elasticity can be realized through ultrasonic equipment, and the change of local blood vessel elasticity can be understood through comparison. It helps to realize earlier diagnosis and prevention of cardiovascular diseases such as atherosclerosis and hypertension. This patent belongs to a new invention in the field of cardiovascular mechanics in medical science, which can be applied to basic research in this field and clinical diagnosis and treatment of related diseases. Background technique [0002] At present, the loss of elasticity of arterial vessels has become one of the important indicators for judging and predicting cardiovascular diseases. We know that the occurrence and development of cardiovascular diseases such as...

Problems solved by technology

However, these indexes are the average indexes of the overall vascular elasticity, and cannot reflect the elastic changes of local arterial vessels. Although PWV can reflect the segmental elasticity, it is difficult to reflect the local elastic changes of a certain section of blood vessels.

At present, there is no index that can accurately reflect the elasticity and mechanical properties of local arteries. This new index proposed by the patent of the present invention fills this gap, and can quantitatively detect and evaluate the elasticity of local arteries. Early diagnosis and prevention of cardiovascular diseases such as hypertension are of great significance
