The Value Of Transcarotid Color Doppler Ultrasound For Early Clinical Prediction Of Coronary Heart Disease

Objective:To investigate the carotid color Doppler ultrasound observation of carotid artery intima-media thickness (IMT) and carotid artery atherosclerotic plaque formation (AP) and other indicators of carotid atherosclerosis and coronary heart disease, the existence and severity of making predictions, for the early diagnosis of coronary heart disease, for its early treatment intervention, prevent vicious cardiovascular events, improve the quality of life of patients, and for the treatment of coronary heart disease, long-termobservation.Methods:Selecting the First Hospital of Shanxi Medical heart medical hospital with suspected coronary artery disease patients with concurrent coronary angiography of160cases, according to the diagnostic criteria of coronary heart disease:coronary angiography, coronary artery stenosis greater than or equal to50%can be diagnosis of coronary heart disease, the subjects were divided into coronary heart disease (90cases) and non-CAD group (70cases), and records related to coronary heart disease group involved coronary artery, number of involved coronary-related coronary artery stenosis extent, according to coronary artery involvement, the number (to the left anterior descending artery, circumflex and right coronary arteries to evaluate) to coronary heart disease group was further divided into a disease group, two lesions, three lesions, respectively the subjects of carotid color Doppler ultrasound, observation, measurement, record carotid intima-media thickness (IMT) and carotid artery atherosclerotic plaque (AP) formation, according to the IMT and AP formation on the degree of carotid atherosclerosis classification, according to the atherosclerotic plaque size, the thickness of the carotid artery affected area, points at the number of carotid atherosclerosis. Gensini score of coronary stenosis. The observation and analysis of the indicators of carotid atherosclerosis and coronary artery disease have any relationship, if there is further to observe, analyze the degree of correlation of the degree of carotid atherosclerosis and coronary artery lesions.Results:Coronary heart disease each lesion group compared with the control group, coronary heart disease the lesions carotid artery intima-media thickness (IMT) than the control group was significantly thicker, the difference was statistically significant, coronary heart disease each lesion group carotid plaque index and compared to the control group was significantly higher, the difference was statistically significant, the probability of coronary heart disease group carotid atherosclerotic plaque formation than the control group was significantly higher. Coronary heart disease with multi-vessel disease group was significantly higher plaque score compared with single-vessel disease group, the difference was statistically significant. Pearson correlation analysis, coronary heart disease the lesions carotid artery intima-media thickness (IMT) of carotid artery plaque (AP) compared with carotid higher IMT values the AP the higher grade of coronary artery stenosis may be The greater the more severe the difference was statistically significant.Conclusion:Observed by carotid ultrasonography of the carotid intima-media thickness (IMT) of carotid atherosclerosis indicators of carotid artery atherosclerotic plaque (AP) can be used as a reliable indicator for early prediction of coronary artery lesions, and As a result of this examination is safety, convenience, economy, repeatability characteristics, can also be used as long-term observation of the therapeutic efficacy of coronary heart disease indicators.
