The Effects of Pumpkin Seed Oil Supplementation on Cardiovascular Function in Postmenopausal Women.

Not Applicable

Completed

• Conditions: Elevated Blood Pressure; Hypertension

• Registration Number: NCT03716960
• Lead Sponsor: Marymount University

Brief Summary

Postmenopausal women have a higher prevalence of cardiovascular (CV) disease than age-match men. Growing evidence from rat studies have demonstrated CV-protective effects of pumpkin seed oil (PSO).

The investigators hypothesis is that PSO would improve CV health in postmenopausal women.

Detailed Description

The purpose of the study is to examine the effects of 6 weeks of PSO on arterial and autonomic function in postmenopausal women. Specific aims of the study are to:

To investigate the extent to which PSO will improve cardiovascular disease risk factors by assessing arterial stiffness, aortic BP and wave reflection, and autonomic function (heart rate variability).

Primary Outcome Measures

Name	Time	Method
Blood pressure	6 weeks	Non-invasive measures of brachial and aortic blood pressure
Pressure Wave Reflection	6 weeks	Using the augmentation index
Arterial Stiffness	6 weeks	Using the stiffness index
Heart rate variability	6 weeks	R-R intervals were collected during 6 min using a validated wireless monitor (Polar 800CX; Polar Electro OY, Kempele, Finland) via a chest strap interfaced with a PC. All R-R intervals were inspected for artifacts and premature beats.
