ULTIMATE Study (Carotid Ultrasound Vs CT Coronary Calcium Scoring to Reclassify Symptomatic Patients With Chronic Coronary Syndrome)

Summary

* Chest pain is one of the most common symptoms of heart disease. This could be due to narrowing in heart's blood vessels, which needs to be investigated. * Currently, people with a low risk of narrowing of heart vessels usually have a CT scan of the heart first. This scan is good at identifying those who do not have significant narrowing. However, the scan has some drawbacks, such as exposure to a small amount of radiation. * We are exploring if ultrasound of the neck vessels might give us similar kind of information as the CT scan. * You will be asked to attend the hospital for one visit to have an ultrasound scan of your neck. * The findings of your neck vessels will be compared with the CT scan of your heart vessels to see if there is a similarity.
