20 Summary Central pulse pressure is more strongly correlated with intermediate cardiovascular phenotypes than peripheral pulse pressure. In a young to middle-aged cohort of normotensive and well-controlled hypertensive subjects, age is the major determinant of intermediate cardiovascular phenotypes. When adjusted for relevant cofactors including age, models containing either cPP or pPP predict intermediate cardiovascular phenotypes equally well. Limitations: cross-sectional design, case-control design and family structure.

21 Perspective and Clinical Relevance Assessment of central haemodynamic parameters provides an integrated view on blood pressure and other determinants of cardiovascular phenotypes. Our data do not support the notion that central blood pressure is a superior determinant of risk than peripheral blood pressure if age is taken into account. Large and prospective studies on the use of central haemodynamic parameters in clinical practice are still required – and under way.
