| Objective: Discuss the values research of change on patients with coronary artery disease in arteriosclerosis and stiffness index Cardio-Ankle Vascular Index (cardio-ankle vascular index CAVI) and ankle-brachial index (ankle-brachial index ABI), Studies CAVI and ABI in the ordinary physical examination crowd's change rule.Methods: A randomly selected Cardiology in our hospital underwent selective coronary angiography examination and treatment of 342 patients, which confirmed by coronary angiography in patients with coronary heart disease (stenosis≥50%) 275 were used as the experimental group (CHD group) and coronary artery disease according to the count into the corresponding sub-group, and the remaining 67 cases (stenosis<50%) as a control group (non-CHD group Including 31 example crown arteries radiography complete normal person) were compared between the two groups in the CAVI,ABI differences. Random selection my courtyard physical examination crowd 1123 people, the basis age section grouping, compared with them on CAVI and ABI difference.Results: (1) confirmed that age, diabetes, hypertension, smoking, blood lipids are risk factors for coronary heart disease. (2) With the severity of coronary stenosis, CAVI progressive increase, the difference between the groups was statistically significant (P <0.01). (3) non-CHD group and the CHD group were in the normal range of ABI, but the CHD group ABI lower than without CHD (P <0.01). ABI multiple vessel disease group than the control group, single-vessel disease group (P <0.05). (4) CAVI (+) predicted a higher sensitivity of coronary heart disease (66.4%), poor specificity (32.7%); ABI prediction of coronary heart disease reduce the low sensitivity (18.0%), but high specificity (96.2% .). (5) Increases the CAVI value along with the age to carry on the markup in the ordinary physical examination crowd,but The ABI value by elevates first then decreases, Namely in 60 to 70 year old of age section presents the inflection point.conclusion: CAVI (-) maybe non-significant independent predictor of coronary heart disease, CAVI (+) it will help early detection of atherosclerosis, and reduced ABI is an independent risk factor for coronary heart disease, can be regarded as Reference index for the diagnosis of coronary artery disease, 60 to 70 year-old senior citizen, the ABI value is smaller than 1.16 prompts has the downward artery system narrow possibility. |
