Abstract

AIMS:

In women with congenital heart disease (CHD), cardiovascular complications during pregnancy are common, but the risk assessment of these patients remains difficult. This study sought to determine the independent role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in addition to other parameters in predicting adverse cardiovascular events during pregnancy in women with CHD.

METHODS AND RESULTS:

We conducted a national, prospective multicentre cohort study. Follow-up with clinical evaluation and echocardiography and NT-proBNP measurement was performed at 20-week gestation. Adverse cardiovascular events occurred in 10.3% of 213 pregnancies. N-terminal pro-B-type natriuretic peptide levels >128 pg/mL at 20-week gestation, the presence of a mechanical valve, and subpulmonary ventricular dysfunction before conception were independently associated with events [odds ratio (OR) 10.6 (P = 0.039), OR 12.0 (P = 0.016), and OR 4.2 (P = 0.041), respectively]. The negative predictive value of NT-proBNP levels <128 pg/mL was 96.9%. N-terminal pro-B-type natriuretic peptide levels >128 pg/mL at 20 weeks of gestation had an additional value in predicting the occurrence of adverse cardiovascular events on the top of the other identified predictors (area under the curve 0.90 vs. 0.78, P = 0.035).

CONCLUSION:

Increased NT-proBNP levels at 20 weeks of gestation are an independent risk predictor of cardiovascular events during pregnancy in women with CHD.
