In a cross-sectional study, we investigated whether left ventricular diastolic function in women with angina pectoris and no obstructive CAD differed from a reference population.

Results The women with angina were slightly older, had higher body mass index, higher heart rate, and more had diabetes compared with controls while systolic blood pressure was lower. In age-adjusted analyses, angina patients had significantly lower E/A (Estimated difference -0.13, 95{\%} CI: -0.17; -0.08), higher left ventricular mass index (5.73 g/m2, 95{\%} CI: 3.71; 7.75), left atrial volume index (2.34 ml/m2, 95{\%} CI: 1.23; 3.45) and E/e' (0.68, 95{\%} CI: 0.30; 1.05) and a larger proportion had higher estimated left ventricular filling pressure (17{\%} versus 6{\%}, p = 0.001). No between group differences were seen for e' or deceleration time. After adjustment for known cardiovascular risk factors, between group differences for echocardiographic parameters remained statistically significant. Conclusions Patients with angina and no obstructive CAD had a more impaired left ventricular diastolic function compared with an asymptomatic reference population. This suggests some common pathophysiological pathway between the two syndromes.",
