Clinical Usefulness
CAVI Age Graph
Shown below is a CAVI-age graph in population of 6793 subjects (male: 3259, female: 3534). With both male and female, aging increases CAVI. When compared by gender, CAVI is higher in male by 4 to 5 years of age (approximately 0.2 in the value) than in female.
CAVI in Patients with Lifestyle-related Diseases
Graphed below are CAVI values in patients with diabetes, hypertension, hyperlipemia, ventricular hypertrophy in ECG, proteinuria, etc. In each patient population, CAVI is significantly higher than in the healthy.
Relations between CAVI and Arteriosclerotic Diseases
Examination of 400 dialysis patients revealed the following relations between CAVI and arteriosclerotic diseases. In patients with coronary artery stenosis (patients undergoing PTCA), abnormal ECG and diabetes CAVI is significantly higher than in patients without these diseases, and in patients with all these 3 diseases complicated CAVI is further increased.
Correlation between CAVI and Blood Pressure
See graphs below. Brachial-ankle pulse wave velocity (baPWV) has strong correlation with both systolic and diastolic pressures. On the other hand, CAVI shows no correlation with diastolic pressure while having weak positive correlation with systolic pressure.
Relations between CAVI and Calcification
The graph below shows relations between CAVI and AACS (aortic calcification degree) in 245 dialysis patients (0.9 ≤ ABI < 1.3). As shown, CAVI values are significantly high in patients of AACS degrees III and V when compared with those of degree 0.
CAVI of Hypertension Group (Male)
Subjects are 3252 examinees undergoing health examination. Compared with the healthy group, the hypertension group in their forties, fifties and sixties shows significantly high CAVI values.
CAVI of Hyperglycemia Group (Male)
Hyperglycemia group in every age group shows significantly higher CAVI value than the healthy.
