Acute myocardial infarction (AMI) in pregnant women is a rare but potentially lethal occurrence that should be carefully managed, especially in consideration of cardiac conditions being a rising cause of maternal deaths. Risk factors for AMI occurrence, in addition to typical cardiac-related risk factors, include medical conditions such as (pre) eclampsia, blood transfusions, thrombophilia and postpartum infections. Being older, multigravida or in the third trimester of pregnancy is also associated with an increased risk. The pathophysiological causes underlying AMI in pregnancy are diverse but generally associated with the coagulative and physiological changes related to the pregnancy. The selection of diagnostic modality and treatment options require careful consideration for pregnancy-related changes as well as risk of harm to the patient and fetus. This paper serves to review available literature regarding an extensive range of management issues that directly impact on maternal and fetal outcomes.

BACKGROUNDAs the Shanghai Obstetrical Cardiology Intensive Care Center, our hospital has accumulated a large number of clinical data of pregnant women with heart disease. This paper is a retrospective analysis of 1142 pregnancies in women with heart disease so as to evaluate the maternal and fetal outcomes of these patients.

METHODSA retrospective analysis was carried out for pregnancies in 1142 women with heart disease who delivered in Shanghai Obstetrical Cardiology Intensive Care Center between 1993 and 2007.

RESULTSIn this study, main heart diseases in pregnancy were arrhythmia (n = 359, 31.4%), congenital heart disease (CHD; n = 291, 25.5%), and myocarditis and its sequelae (n = 284, 24.9%); based on the functional classification criteria of New York Heart Association (NYHA), more than half (n = 678, 59.4%) of patients were classified NYHA Class I; pregnant women in NHYA Class I-II (n = 951, 83.3%) commonly had arrhythmia, myocarditis and its sequelae, while those in NHYA Class III-IV (n = 191, 16.7%) mainly had CHD, rheumatic heart disease (RHD), cardiopathy induced by hypertensive disorders complicating pregnancy, and peripartum cardiomyopathy (PPCM). Cardiac failure occurred in 97 (8.5%) patients, and 8 (0.7%) maternal deaths and 12 (1.1%) perinatal deaths were reported in this study. Compared with those in NHYA Class I-II, women in NHYA Class III-IV had a significantly lower gestational age at birth (P < 0.05), lower birth weight (P < 0.01), and higher incidence of preterm delivery, small for gestational age and perinatal death (P < 0.01). The incidence of cardiac failure in pregnant women with cardiopathy induced by hypertensive disorders complicating pregnancy and PPCM was relatively high, with a rate of 80% and 52.2%, respectively. After cardiac operation, 131 (90.3%) women were in classified NHYA Class I-II and 14 (9.7%) in NHYA Class III-IV.

CONCLUSIONSArrhythmia is the type of heart disease that has a highest incidence in patients with heart disease in pregnancy, while main types of heart disease that impair cardiac function are CHD and RHD; cardiac failure is more frequently caused by cardiopathy induced by hypertensive disorders complicating pregnancy and PPCM; impaired cardiac function increases perinatal morbidity; cardiac surgery before pregnancy could improve the cardiac function.

Aortic dissection accompanying with preeclampsia during pregnancy can be lethal to both the mother and the fetus and carries a high mortality. Of the 2 preeclampsia patients with aortic dissection, one was Type B aortic dissection, occurring in postpartum period. The patient was treated medically and underwent catheter-based stent-graft treatment with fenestration technique. Another patient was Type A acute dissection, occurring in the third trimester. This patient was undiagnosed and both died. Although extremely rare, aortic dissection might be a possibility in preeclampsia pregnant women, the differential diagnosis of chest and/or epigastric pain in preeclampia patient should be thoroughly investigated and treated.

The prevalence of hypertensive disorders in China was much higher than that in the United States. Considering the large population with wide geographic area of China, we aimed to add more information regarding the risk factors for hypertensive disorders of pregnancy. A case-control study was performed on 373 hypertensive cases and 507 normotensive controls. Participants were recruited from 2008 to 2014 in Yichang Maternal and Child Health Care Center in Hubei province and Anyang Maternal and Child Health Care Hospital in Henan province, China. Socio-demographic factors, family- related factors, pregnancy-associated factors, factors related to daily life behaviors and psychosocial factors were investigated with respect to hypertensive disorders in pregnancy through well-designed questionnaire. Chi-square test, t-test, univariate logistic regression analysis, and multivariate logistic regression analysis were used to find the possible risk factors behind hypertensive disorders in pregnancy. The results showed that family history of cardiovascular diseases (OR=6.18, 95% CI, 2.37 to 16.14), history of pregnancy-induced hypertension (OR=16.64, 95% CI, 5.74 to 48.22), low maternal educational level (OR=2.81, 95% CI, 1.30 to 6.04), and poor relationship with their parents-in-law (OR=3.44, 95% CI, 1.55 to 7.59) had statistically significant associations with hypertensive disorders in pregnancy through multivariate logistic regression analysis. Increased maternal age, increased pre-pregnancy body mass index, living in rural area, low paternal education level, family history of hypertension, passive smoking one year before and/or in pregnancy, and poor sleeping quality were significantly associated with hypertensive disorders in pregnancy from univariate logistic regression analysis while the associations became uncertain when they were entered for multivariate logistic regression analysis. It was concluded that family history of cardiovascular diseases, history of pregnancy-induced hypertension, low maternal educational level, and poor relationship with their parents-in-law were independent risk factors for hypertensive disorders among Chinese pregnant women.

OBJECTIVETo study the relationship between pregnancy-induced hypertension (PIH) and catecholamine levels.

METHODSCatecholamines levels in maternal and fetal blood were determined in 116 patients with PIH and 40 normal control subjects using high performance liquid chromatography. The normal control subjects and PIH cases were selected from patients at term pregnancy receiving elective cesarean section.

RESULTSPlasma norepinephrine (NE) levels were significantly higher in patients with severe PIH than those in control subjects (P < 0.05). Both patients and control subjects had higher NE levels in the umbilical artery blood than in the umbilical vein blood (P < 0.05). NE levels in the umbilical artery blood were five times higher than those in the maternal blood.

CONCLUSIONThe pathogenesis of PIH may relate to catecholamine concentrations in fetus.

Pregnancy in patients with Eisenmenger syndrome (ES) is associated with high maternal mortality rates of 30%‒50%, or even up to 65% in the case of a cesarean section (Yuan, 2016). Here, we report a case of term pregnancy complicated with ES and severe pulmonary artery hypertension (PAH), which was managed by a multidisciplinary team (MDT) and resulted in an uncomplicated delivery via elective cesarean section. The goal of this study is to emphasize the importance of multidisciplinary approach in the management of pregnancy with ES, which can profoundly improve maternal and infant outcomes.
