Problems solved by technology

At present, the main method of diagnosis is through electrocardiogram and other methods, which is inconvenient and time-consuming for patients.
So far, there is no non-invasive, fast, economical, and home-usable method for judging whether myocardial infarction and heart failure occurs, and there is no non-invasive, fast, economical, and home-usable method that can be used to screen out patients with myocardial infarction and heart failure during physical examination method
At the same time, there is no non-invasive, fast, economical, and home-usable method for judging the prognosis of myocardial infarction and heart failure. Therefore, inventing a non-invasive, fast, economical, and home-usable method for judging whether myocardial infarction and heart failure is onset can be A non-invasive, rapid and economical method for screening out patients with myocardial infarction and heart failure during physical examination, as well as a non-invasive, rapid, economical method for judging the prognosis of myocardial infarction and heart failure that can be used at home, has extremely important socio-economic Significance and clinical value

Embodiment 1

[0027] Example 1: The excitation light is in the blue light band, and the relationship between nail autofluorescence intensity and myocardial infarction or heart failure.

[0028] According to the present invention, an instrument is used to perform real-time non-invasive imaging of skin autofluorescence on nails of people with myocardial infarction or heart failure or non-myocardial infarction or heart failure. The experimental results showed that compared with the nail autofluorescence intensity of non-myocardial infarction or heart failure patients, the nail autofluorescence intensity of patients with myocardial infarction or heart failure was significantly increased ( figure 1 )

Embodiment 2

[0029] Example 2: The blue light band as the excitation light is the relationship between the difference in autofluorescence intensity at the left and right symmetrical positions of the subject's nails and myocardial infarction or heart failure.

[0030] According to the present invention, an instrument is used to perform real-time non-invasive imaging of skin autofluorescence on nails at symmetrical positions on the left and right sides of patients with myocardial infarction or heart failure or non-myocardial infarction or heart failure. The experimental results showed that the autofluorescence intensity of nails in non-myocardial infarction or heart failure patients was symmetrical, while the autofluorescence intensity of nails in the left and right symmetrical positions of patients with myocardial infarction or heart failure was asymmetric. ( figure 2 )

[0031] Based on the technology of the present invention, it will be applied (including but not limited to): 1. Myocard...

Abstract

The invention relates to a method for judging myocardial infarction, heart failure and healing degrees on the basis of zygomorphy and intensity of nail autofluorescence and an application thereof, andparticularly provides a method for detecting the myocardial infarction, heart failure and healing degrees on the basis of detecting the zygomorphy and intensity of the nail autofluorescence. The method is non-invasive, efficient, simple, economical, high in accuracy and good in repeatability.

Description

technical field [0001] The invention relates to the left and right spatial distribution and intensity of human nail autofluorescence as a method for judging the onset of myocardial infarction and heart failure. Specifically, it refers to judging whether the subject suffers from myocardial infarction or heart failure, and the degree of myocardial infarction or heart failure by comparing the distribution of fluorescence intensity on the left and right of the human nail and the intensity of autofluorescence. Background technique [0002] In my country and other countries in the world, myocardial infarction and heart failure (heart failure) are one of the most serious diseases that cause death and lifelong disability. Myocardial infarction in China has shown an obvious upward trend in recent years, with at least 500,000 new cases and at least 2 million current cases each year. Heart failure is a severe and terminal stage of cardiovascular disease, and the number of patients con...
