Abstract

<a name=“OLE_LINK2”></a><a name=“OLE_LINK1”>Hypertensive pregnancy (HP) disorders have been linked to a four‐fold increased risk for development of future cardiovascular diseases. We examined whether history of HP in postmenopausal women (N=20, 59±5 yr) influenced the risk factors for cardiovascular disease as assessed by aortic pulse wave characteristics, compared to age and parity matched controls (N=18, 60±4 yr). Non‐invasive aortic pressure waveforms were synthesized from high‐fidelity pressure waveforms obtained from SphygmoCor applanation tonometry using the radial artery. Aortic systolic and diastolic blood pressure (ASBP, ADBP), aortic augmentation index (AIx), augmented pressure (AP), aortic pulse pressure (APP), and left ventricular wasted energy (Ew) were calculated from the generated aortic pressure waveform. There were no differences in ASBP (125±4 vs. 129±4 mmHg), ADBP (79±2 vs. 81±2 mmHg), AP (17±2 vs. 17±2 mmHg), AIx (35±2 vs. 29±1%), AIx @75BPM (31±2 vs. 29±1%), Ew (3313±338 vs. 3364±432 dynes/cm2/s), between women with a history of HP vs. matched controls, respectively (P>0.05 for all). Body mass index was significantly higher in women with a history of HP (30.6±1 vs. 26.7±1 kg/m2, P<0.05), however it did not statistically influence any of the indices (P>0.05 for all). Our results suggest that postmenopausal women with a history of HP do not demonstrate elevated aortic blood pressure or altered aortic pulse wave characteristics in comparison to matched controls. </a>Supported by: National Institute of Aging 1P50AG044170‐01 and CTSA UL1 TR000135 and HL 118154
