Abstract

Objectives: To examine the relationship between arterial stiffness and diastolic function in healthy normotensive subjects.

Methods: For this study, 43 male (40±10 years) and 64 female (40±9 years) subjects were recruited. All were lifelong non-smokers, normolipidaemic, normoglycaemic and had normal 24-hour blood pressure responses (SBP\DBP <140\90). For each subject, metabolic profile and anthropometric measurements were recorded. Carotid-femoral pulse wave velocity (PWV) was measured to assess arterial stiffness. Early/late mitral valve filling velocity (MV E/A) and isovolumetric relaxation time (IVRT) was used to assess diastolic function.

Results: The indices of diastolic function, LV IVRT & MV E/A ratio, and 24-hour ambulatory systolic & diastolic blood pressure were significantly correlated with PWV. In addition, age, anthropometric and metabolic values, such as waist/height ratio, fasting glucose (Glucose Fast), glycosylated haemoglobin (HbA1c) were also significantly correlated with PWV (Table 1). In a multiple regression analysis, age, 24-hour DBP, and MV E/A ratio remained independent predictors of PWV.

Conclusion: Left ventricular diastolic function is associated with arterial stiffness even in “healthy” normotensive subjects, suggesting, that changes in arterial and left ventricular walls occur in parallel.
