  • Publication number: 20190049464
    Abstract: Novel means capable of detecting an arteriosclerotic lesion in a body by a less invasive, simple method is disclosed. The method for detecting arteriosclerosis according to the present invention comprises measuring the myosin heavy chain 11 level in a blood sample isolated from a subject. A myosin heavy chain 11 level higher than that of a healthy individual is indicative of the presence of arteriosclerosis in the subject. Since the present invention enables detection of arteriosclerosis by a blood test, a less invasive, simple test can be carried out. Unlike methods for testing only particular regions such as carotid artery ultrasonography, the present invention is expected to reflect the conditions of blood vessels in the whole body.
