Abstract
Objectives To investigate the association between left ventricular (LV) diastolic dysfunction and multiparity in patients with suspected coronary artery disease (CAD). Design Cross-sectional study. Setting Linked secondary and tertiary care records from 29 cardiac centres which participated in KoRean wOmen'S chest pain rEgistry. Participants 960 women with suspected CAD who underwent invasive coronary angiography from February 2011 to May 2017. The patients were classified by parity number, as follows: low-parity, 0 to <3; multiparity, >= 3 pregnancies. Main outcome measure Prevalence of LV diastolic dysfunction. Results There were 302 and 658 low-parity and multiparity patients, respectively. The prevalence of LV diastolic dysfunction was significantly higher in the multiparity than in the low-parity group. The multiparity group had significantly lower E and e septal velocities and E/A ratio, and had a significantly higher E/e ratio and right ventricular systolic pressure, which are parameters of LV diastolic dysfunction, than the low-parity group. The prevalence of CAD was significantly higher in the multiparity than in the low-parity group. Receiver operating characteristic curve analysis identified a parity of 2.5 as the cut-off for predicting LV diastolic dysfunction (area under the curve, 0.66; sensitivity, 74.1%; specificity, 52.0%; 95% CI 0.607 to 0.706; p<0.001). After adjustment for confounding factors, multivariate regression analysis showed that multiparity had a 1.80-fold increased risk for LV diastolic dysfunction (OR 1.80, 95% CI 1.053 to 3.081, p=0.032). Conclusions The prevalence of LV diastolic dysfunction was higher in multiparity than in low-parity women with suspected CAD. Multiparity was an independent risk factor for LV diastolic dysfunction. LV diastolic dysfunction should be evaluated in multiparous women for the risk of subsequent cardiovascular disease and facilitate the initiation of appropriate treatment.
