Recent research from the University of Colorado Denver shows why arteries stiffen in postmenopausal women.
A specific chemical cofactor was found from the research, which significantly improves vascular function in postmenopausal women. The BH4 or tetrahydrobiopterin plays a crucial role in the arterial health of women.
"Nitric oxide causes arteries to dilate; without it, they are more constricted, which can lead to arterial stiffening," said Kerrie Moreau, associate professor of medicine at the university's school of medicine. "That stiffening can cause high blood pressure, thickening of the left ventricle and increase the risk for stroke, heart disease and dementia."
Postmenopausal women face a greater risk of incurring various health and medical-related issues than their younger counterparts. In addition, more women are playing the role of breadwinner in families across the country and thus should be equipped with a life insurance policy.
