Arterial stiffness in fertile women with metabolic syndrome

Introduction: Although metabolic syndrome (MetS) is evidently associated with the risk of cardiovascular disease (CVD), recently its use has been questioned. We studied the utility of MetS diagnosis when estimating individual CVD risk. Methods: We compared 27 fertile women with MetS and 27 counterparts without the syndrome, matched pairwise according to well-known risk factors of CVD. Pulse wave velocity (PWV) and central blood pressure (cBP) were determined noninvasively via a SphygmoCor device. Arterial compliance was measured noninvasively with an HDI/PulseWave (TM) CR-2000 arterial tonometer. Results: PWV (7.1 +/- 2.5 versus 6.5 +/- 1.1 m/s, p = .037), and both systolic (120.9 +/- 12.2 versus 111.5 +/- 16.0 mmHg, p = .031) and diastolic cBP (81.3 +/- 8.5 versus 74.1 +/- 11.2 mmHg, p = .035) were higher in the MetS group. Systemic arterial compliance values were lower in both large (15.1 +/- 8.0 versus 16.1 +/- 4.4 mL/mmHg x 10, p = .034) and small arteries (7.1 +/- 2.5 versus 9.3 +/- 3.2 mL/mmHg x 100, p = .010) in women with MetS. Conclusions: Fertile women with MetS had increased arterial stiffness, as measured by three different methods. Our results highlight the utility of MetS when revealing increased individual CVD risks in fertile-aged women.
