7/31/2023 0 Comments Cost of carotid doppler68% of all heart attacks occur in patients with less than 50% blockage and 86% of heart attacks occur in patients with less than 70% blockage. At 70% blockage, most patients will still pass a treadmill stress test (if the blockage were in the coronary artery). The difference matters!Īdditionally, most physicians do not consider the blockage in the carotid artery to be clinically significant until it is 70% or more. Additionally, it is unable to determine the quality of the plaque. The carotid doppler ultrasound does not look at the health of the artery, only if it has plaque and to what degree. Unfortunately, you won’t really see a significant change in blood flow until the stenosis (blockage due to plaque build up) is greater than 50%. The idea is that when there is obstruction to blood flow it suggests that there is some plaque build up restricting this blood flow. The carotid doppler ultrasound is looking at blood flow through the carotid artery. So what is the difference? Carotid Doppler Ultrasound Upon further questioning, he had a “conventional” carotid ultrasound and not a CIMT. Just the other day I had a patient tell me that he didn’t need a CIMT test because he had a carotid ultrasound a year ago. However, CIMT testing is NOT the same! The difference between a Carotid Ultrasound and CIMT? You may have heard of carotid ultrasounds before. All men over the age of 45 and all women over the age of 55 should get CIMT Testing.Īdditionally, if you have other risk factors for cardiovascular disease then you should get this testing even younger. We recommend and perform CIMT Testing in our clinic. Many people have significant cardiovascular disease and are high risk for a heart attack yet they have absolutely no idea. Cardiovascular disease is the #1 cause of death for men and women.
