Classification of Hemodynamics Using a Diagnostic Nomogram and Ambulatory Blood Pressure Data

Abstract

This article provides a detailed overview of the hemodynamic nomogram, a new diagnostic tool in hemodynamics based on the linear regression modeling of ambulatory blood pressure monitoring data (ABPM) and the Support Vector Machine (SVM) classifier. We investigated the classification capability and practical usage of the diagnostic nomogram, as well as cardiovascular phenomena described and limitations of linear modeling.One of the practical applications of the nomogram is the ability to retrace changes in ABPM parameters due to antihypertensive therapy. Misclassifications are explained by nonlinear properties of the hemodynamics of diastolic type.
