Noninvasive vascular function tests for the future prediction of primary cardiovascular diseases.

: Cardiovascular diseases (CVDs), still remain the main causes of death and disability in the US and worldwide, and the prediction for their future incidence is not well established. The utilization of the new cardiovascular risk score (CVRS) developed by the new ACC/AHA blood pressure treatment guidelines has improved the 10-year prediction of CVDs. However, its predictive value could be further increased with the addition of other risk factors identified with the use of several noninvasive vascular tests. These tests include, the older tests such as flow mediated dilation (FMD), pulse wave velocity (PWV), pulse pressure (PP), and the newly developed noninvasive vascular tests of, reactive hyperemia-peripheral arterial tonometry (RH-PAT), cardio-ankle vascular index (CAVI), and the inter-arm/inter-leg pressure difference (IAPD/ILPD).: In order to get a current perspective regarding the usefulness of these new noninvasive vascular tests for the future prediction of CVDs, a Medline search of the English language literature was conducted between 2014 and 2019 using the terms cardiovascular disease, coronary heart disease, noninvasive vascular tests, risk factors, and 26 pertinent papers were retrieved.: The analysis of results from these papers showed that these noninvasive vascular tests have an independent predictive value for the future incidence of CVDs and hypertension. However, their long-term predictive value is not well established, since there are no currently, available data from long-term clinical outcome studies.: The analysis of data from the retrieved papers demonstrated that the new noninvasive vascular tests have an independent predictive value for the future incidence of CVDs and hypertension. However, their long-term predictive value is not established as yet for the lack of long-term outcome studies. When the currently ongoing long-term trials are completed, it is quite possible that the data from these tests added to CVRS could enhance its predictive value.
