There is widespread acceptance of the increased prevalence of cardiovascular disease occurring within 1 to 2 decades in women following a preeclamptic pregnancy. More recent evidence suggests that the deranged biochemical and echocardiographic findings in women do not resolve in the majority of preeclamptic women following giving birth. Many women continue to be hypertensive in the immediate postnatal period with some exhibiting occult signs of cardiac dysfunction. There is now promising evidence that with close monitoring and effective control of blood pressure control in the immediate postnatal period, women may have persistently lower blood pressures many years after stopping their medication. This review highlights the evidence that delivering effective medical care in the fourth trimester of pregnancy as a means of improving the long-term cardiovascular health of women after a preeclamptic birth.

IntroductionMyocardial infarction with non-obstructive coronary arteries (MINOCA) predominantly affects younger females. Women with a history of gestational hypertension (GH), preeclampsia (PE), and gestational diabetes mellitus (GDM) are subjected to an elevated lifetime risk of cardiovascular disease. However, data on the potential association between these obstetric complications and MINOCA is lacking. Therefore, the current study aimed to provide insight in the prevalence of metabolic and hypertensive pregnancy disorders (MHPD) in MINOCA patients and their clinical characteristics.MethodsIn this observational cohort study conducted at the Zuyderland Medical Center and Maastricht University Medical Center in the Netherlands, patients were enrolled if they were identified as having MINOCA. Data on individual patient characteristics, laboratory results, electrocardiography as well as (non-)invasive imaging procedures were derived from the electronic health record system. Patients were asked to complete a questionnaire about prior MHPD including GDM, GH, and PE. Patients were grouped into those with MHPD and those with prior uncomplicated normotensive pregnancy (or pregnancies; NP).ResultsAfter excluding patients without 1-year follow-up (n = 53), 86 female MINOCA patients remained eligible for analysis. Of the total female population, 25 (29.1%) patients had MHPD, including GH (n = 19; 22.1%), PE (n = 4; 4.7%), and GDM (n = 7; 8.1%). The MHPD patients showed higher rates of chronic hypertension (84.0 vs. 55.7%; p = 0.013), hypercholesterolemia (64.0 vs. 34.4%; p = 0.012), a family history of CVD (84.0 vs. 45.9%; p = 0.001), gout or rheumatic arthritis (16.0 vs. 1.6%; p = 0.024), and were more often non-smokers (45.8 vs. 78.3%; p = 0.004), compared to the NP patients. Moreover, MHPD patients were more likely to use cardiovascular medications at baseline. A trend toward no specific cause found for the MINOCA event was observed in MHPD patients compared to the NP group (64.0 vs. 42.6%, p = 0.072).ConclusionA history of metabolic and hypertensive pregnancy disorders occurred in one-third of female MINOCA patients. In these patients, conventional cardiovascular risk factors were more prevalent compared to NP patients. In most MHPD patients, the specific cause for MINOCA remained unclear.
