Suhrs HE, et al. – This study is performed to investigate whether a history of reproductive risk factors was related to coronary microvascular dysfunction (CMD) in women with angina pectoris and no obstructive coronary artery disease (CAD). The lack of the relationship between coronary microvascular function and a history of reproductive risk factors, migraine and Raynaud's phenomenon recommends that a common vascular pathophysiological mechanism underlying these conditions is unlikely.
