N2 - BACKGROUND: Reproductive risk factors such as preeclampsia and recurrent miscarriages have been associated with adverse cardiovascular (CV) events. Underlying coronary microvascular dysfunction (CMD) may be a common denominator.PURPOSE: We investigated whether a history of reproductive risk factors was associated with CMD in women with angina pectoris and no obstructive coronary artery disease (CAD).METHODS: Participants from the iPOWER study, including women with angina pectoris and no obstructive CAD (<50% stenosis), were invited to complete an electronic survey regarding reproductive risk factors: recurrent miscarriages, gestational diabetes, preeclampsia, rhesus immunity, polycystic ovary syndrome and menopausal status as well as migraine and Raynaud phenomenon. CMD was assessed by transthoracic Doppler echocardiography with measurement of coronary flow velocity reserve (CFVR) during high-dose dipyridamole infusion, and analyzed in three categories with cut-off points at 2.0 and 2.5. Associations between CFVR and a history of reproductive risk factors were examined by age-adjusted trend test.RESULTS: The questionnaire was completed by 613 women (73% of those invited), of whom 550 had a successful CFVR measurement. There was no significant difference in baseline characteristics between participants and non-participants. Median (interquartile range (IQR)) age was 62.8 (54.8; 68.7) years, median (IQR) BMI 26.2 (23.2; 29.8) kg/m2, and 81.5% were postmenopausal. We did not find any significant associations between any of the reproductive risk factors, Raynaud's phenomenon or migraine and CFVR.CONCLUSION: The lack of association between coronary microvascular function and a history of reproductive risk factors, migraine and Raynaud's phenomenon suggests that a common vascular pathophysiological mechanism underlying these conditions is unlikely.
