Carotid Intima Media Thickness as a Cardiovascular Risk Factor
CIMT is a painless, noninvasive test that takes about 10-15 minutes to perform. CIMT uses ultrasound (so there is no radiation) and does not require the patient to disrobe.
CIMT is recommended by both the American Heart Association and the American College of Cardiology. As many as 50-60% of those who die from heart attacks or strokes have no previous signs or symptoms. These patients may have been classified as low or intermediate risk based on traditional risk factors. CIMT is more accurate in predicting disease than any other risk factor alone. CIMT significantly improves the assessment of cardiovascular risk in an individual by directly looking at the blood vessels. CIMT will catch more people with disease who were felt to be normal on stress tests. Stress tests only become positive when a patient generally has 70% or greater blockage of a coronary artery. We certainly want to know if we are at risk long before we have a blood vessel that is more than 70% blocked!
As part of our ongoing commitment to provide the latest advancements in preventive medicine, Cenegenics is now offering an additional, state of the art, screening tool for vascular disease called CIMT. CIMT stands for Carotid Intima Media Thickness and refers to the combined thickness of the inner two layers (intima and media) of the carotid artery, which lies in the neck. The measurement of the thickness of the intima and media layers of the common carotid artery is highly predictive of future events (i.e. heart attack, stroke, sudden cardiac death).
Just the Facts for Men | The goals of the Cenegenics program are to keep our patients at the lowest possible risk for the various diseases associated with aging and to improve their quality of life. This is accomplished through early detection, identification of risk factors, and proactive strategies designed to prevent disease as much as possible, rather than treating it once it is established.
See the Cardio Health System device’s page on our site for more information on the specific method/device we will be using to measure CIMT.
The test will be included in the initial Executive Health Evaluation.
Cenegenics uses the Panasonic Cardio Health Station to measure carotid intima media thickness as a cardiovascular risk factor as part of the CIMT exam.
The Cardio health station is FDA cleared, in-office ultrasound imaging that helps you directly identify atherosclerotic cardiovascular disease (ASCVD) allowing you to make a more informed decision about your patients’ treatment options.
The Physicians' Challenge
Assessment of cardiovascular risk in asymptomatic patients with cardiovascular disease is one of the leading causes of death globally. To assess risk, doctors typically review traditional risk factors, such as total cholesterol, blood pressure, smoking history, age, gender, lipid profile (HDL/LDL levels), and family history. However, these conventional tests can be poor predictors of future atherothrombotic events. Relying on these factors may result in misclassification of risk. In a major study of 136,905 patients hospitalized with coronary artery disease, only 23% had high LDL levels* (above 130 mg/dl) and would be identified by traditional risk factors. Yet, in a large outcome study of 10,000 asymptomatic subjects with a 10 year follow-up (mean age = 53), ultrasound identified 98.6% of future atherothrombotic events.**

The Panasonic Solution: Find a Plaque, Treat It.
We have engineered a product that not only improves your ability to see the underlying disease, but also fits seamlessly into your treatment regimen. Innovative ultrasound imaging technology allows for direct identification of atherosclerotic cardiovascular disease (ASCVD). By combining traditional risk factors with imaging, physicians are able to gather a more comprehensive understanding of their patients’ cardiovascular health.
The CardioHealth Station in the hands of a trained
professional is the perfect in-office tool. Driven by advanced hardware, it automates many of the steps which a sonographer would usually need to understand and perform, making it easy to start using right away and on your own schedule.
Easy to Integrate into Your Practice to Help You Start Making Informed Decisions
Carotid Intima-Media Thickness (CIMT) and Plaque Assessment by Trained Medical Residents: Validation and Preliminary Testing of a Training Protocol.
A recent study published by physicians out of Mayo Clinic and the University of Southern California assessed how easy it was to train medical residents to use ultrasound imaging to identify plaque and measure CIMT. The conclusion was that it was easy to rapidly train medical residents, who had no prior ultrasound training, to identify ASCVD with an accuracy comparable to experts.*

Rapid Screening for Subclinical Atherosclerosis by Carotid Ultrasound Examination. The HAPPY (Heart Attack Prevention Program for You) Substudy.
A major study done in India, under the guidance of leading physicians from Mt. Sinai, sought to determine the feasibility of performing ultrasound imaging in a rural young population with few to no risk factors. The results proved that not only was rapid community screening of subclinical atherosclerosis possible, but also useful for identifying the high prevalence of atherosclerotic cardiovascular disease (ASCVD) where traditional risk factors were not available.*

**Accurate as of March 2011
In most cases, the entire test takes no longer than five minutes allowing you to create a comprehensive cardiovascular risk assessment very quickly. A detailed report is generated based on traditional risk factor scores (FRAMINGHAM, SCORE or PROCAM) and the results of the ultrasound examination (plaque and IMT) are plotted against your choice of a major study, whether it be ARIC, MESA, or CAPS. Developed in close cooperation with key opinion leaders in preventive cardiology and subclinical atherosclerosis imaging, the report is optimized for you and your patients. The combination of schematic and actual ultrasound images to depict wall thickness and arterial plaque may serve as a clever solution to increasing patient adherence to treatment.

Is Testing for Atherosclerotic Disease Recommended?
Yes! Detecting early stage Atherosclerosis by finding focal lesions or an abnormal IMT is more highly recommended by national societies than several other well-known tests.
