Abstract

BACKGROUND: Left ventricular diastolic dysfunction and nocturnal "nondipping" of blood pressure detected via ambulatory blood pressure monitoring are predictors of increased cardiovascular morbidity.

METHODS: A prospective cohort study including normotensive women with a history of preeclampsia in their current pregnancy was conducted. All cases were subjected to 24-hour ambulatory blood pressure monitoring and 2-dimensional transthoracic echocardiography 3 months after delivery.

RESULTS: This study included 128 women with a mean (SD) age of 28.6 (5.1) years and a mean (SD) basal blood pressure of 123.1 (6.4)/74.6 (5.9) mm Hg. Among the participants, 90 (70.3%) exhibited an ambulatory blood pressure monitoring profile illustrating nocturnal blood pressure "dipping" (the mean night to day time blood pressure ratio ≤ 0.9), whereas 38 (29.7%) were nondippers. Diastolic dysfunction (impaired left ventricular relaxation) was present in 28 nondippers (73.7%), whereas none of the dippers exhibited diastolic dysfunction. Women with severe preeclampsia were more frequently nondippers (35.5% vs 24.2%; P = .02) and experienced diastolic dysfunction (29% vs 15%; P = .01) than were those with mild preeclampsia. Severe preeclampsia (odds ratio [OR], 1.08; 95% CI, 1.05-10.56; P < .001) and history of recurrent preeclampsia (OR, 1.36; 95% CI, 1.3-4.26; P ≤ .001) were significant predictors for nondipping status and diastolic dysfunction (OR, 1.55; 95% CI, 1.1-2.2; and OR, 1.23; 95% CI, 1.2-2.2, respectively; P < .05).

CONCLUSION: Women with a history of preeclampsia were at higher risk for developing late cardiovascular events. The severity and recurrence of preeclampsia were significant predictors of both nondipping profile and diastolic dysfunction.
