Cardiovascular Ultrasound Combined With Non-invasive Screening for the Detection of Undiagnosed Cardiovascular Disease: A Literature Review

Abstract

Non-invasive screenings have been widely utilized in the United States and worldwide to provide early identification of cardiovascular disease, allowing for earlier diagnosis and treatment. Screening sonography detects valve disease, cardiac dysfunction, and carotid disease in 5% to 20% of the population. This review discusses the current data regarding cardiovascular screening, the methodologies, and the resources required for performance of screenings. Cardiac and carotid sonography is highly accurate and discovers cardiovascular diseases that impact quality of life and risk of future events. Screenings are performed in a variety of settings and accuracy depends on the quality of personnel performing the non-invasive testing, the equipment utilized, and the personnel interpreting the studies. Despite the potential benefit for disease detection, population screening to detect cardiovascular disease is not widely supported by national organizations due to the theoretical cost of further testing and lack of cost versus benefit data. Additional studies are necessary to compare costs and benefits of non-invasive cardiovascular screening in the community setting.
