- Coronary heart diseases are on the rise and atherosclerosis is a strong indicator of heart disease.
- But there has been no accurate diagnostic tool for atherosclerosis.
- New findings state that investigating the radial artery using ultrasound could be a new way to diagnose atherosclerosis.
Atherosclerosis is the hardening of arteries. It has always been a strong indicator of coronary heart disease compared to the traditional risk factors of race, age, gender and metabolic profile.
But there has been no simple way to diagnose the condition or to monitor the response of patients to treatment.
A new study has found that a useful way of assessing atherosclerosis can be by monitoring the peripheral arteries, which are easily accessible by ultrasound, thus becoming an important diagnostic tool.
The authors assessed the arteries of 48 cadavers to determine risk factors for atherosclerosis. They sampled 13 different arteries based on their anatomical location, including segments of carotid, central and peripheral arteries.
The central artery group included arteries that are non-palpable and commonly lead to ischemic diseases when occluded. The peripheral artery group included arteries that are accessible to palpation. The carotid artery group included branches of the carotid artery.
"It is very gratifying to combine the work perspectives of an analytical anatomist with those of a physician and a medical student to leverage synergies and discover outcomes that can be applied in a clinical setting", said Brian L. Beatty, senior author of the study.
The researchers utilized histopathology to confirm the correlations between arteries and ischemic diseases. They investigated the distribution of atherosclerosis in various arteries throughout the body, by sampling segments from the carotid arteries and peripheral vessels and compared them to clinically relevant central arteries of the torso.
The results showed that the radial artery, which is a peripheral vessel, exhibited a positive correlation between both the pathologic left coronary and bifurcation of the carotid arteries.
The study proposes investigating the radial artery as a clinically accessible location to monitor with ultrasound when assessing a patient's risk for ischemic cardiovascular disease.
Further studies are needed to evaluate the clinical utility of radial artery ultrasonography to assess cardiovascular risk.
