This, however, appears to be an extreme view, though, of course, when the lesion is serious and the compensation faulty, the dangers of childbearing should be carefully explained. Whitridge Williams (1903) As Williams recognized more than a century ago, pregnancy in those with significant heart disease can be extremely hazardous and may lead to decompensation and death. In an analysis of maternal mortality in the United States between 2011 and 2013, the causes previously responsible for most maternal deaths-hemorrhage, hypertensive disorders, and embolism-continued to show declining rates. In contrast, deaths attributable to cardiovascular diseases were responsible for approximately 26 percent of all pregnancy-related deaths (Creanga, 2017). Cardiovascular diseases also account for significant maternal morbidity and are a prominent reason for obstetrical intensive care unit admissions (Small, 2012). The rising prevalence of cardiovascular diseases complicating pregnancy is likely multifactorial and includes the higher rates of obesity, hypertension, and diabetes (Klingberg, 2017). Indeed, according to the National Center for Health Statistics, almost half of adults aged 20 and older have at least one risk factor for cardiovascular disease (Fryar, 2012). This early rise stems from augmented stroke volume, which results from lowered vascular resistance. Later in pregnancy, resting pulse and stroke volume are even higher because of greater end-diastolic ventricular volume that results from pregnancy hypervolemia. These changes translate to a cardiac output that enlarges across pregnancy to average 40 percent higher at term. These adaptations are even more profound in multifetal pregnancies (Kametas, 2003; Kuleva, 2011). Namely, pregnancy is not characterized by hyperdynamic function or a high cardiac-output state. Hemodynamic Changes in 10 Normal Pregnant Women at Term Compared with Repeat Values Obtained 12 Weeks Postpartum Women with underlying cardiac disease may not always accommodate these changes, and ventricular dysfunction leads to cardiogenic heart failure. A few women with severe cardiac dysfunction can experience evidence of heart failure before midpregnancy. In most, however, heart failure develops peripartum, when labor, delivery, and several common obstetrical conditions add undue cardiac burdens. Ventricular Function in Pregnancy Ventricular volumes and mass accrue to accommodate pregnancy-induced hypervolemia. This is because these alterations are accompanied by substantive ventricular remodeling-plasticity-which is characterized by eccentric expansion of left-ventricular mass that averages 30 to 35 percent near term. All of these adaptations return to prepregnancy values within a few months postpartum. For given filling pressures, there is appropriate cardiac output so that cardiac function during pregnancy is eudynamic. In nonpregnant subjects with a normal heart who sustain a high-output state, the left ventricle undergoes longitudinal remodeling, and echocardiographic functional indices of its deformation provide normal values. In pregnancy, there instead appears to be spherical remodeling, and these calculated indices that measure longitudinal deformation are depressed. Syndromes

Whitridge Williams (1903) At the beginning of the last century, obesity was not terribly problematic, and with few exceptions, Williams did not refer to its adverse obstetrical effects. Indeed, by 2014, more than a third of all adults in the United States were obese (Ogden, 2015). The adverse health aspects of obesity are staggering and include risks for diabetes mellitus, heart disease, hypertension, stroke, and osteoarthritis. Obese gravidas and their fetuses are predisposed to various serious pregnancy-related complications and to higher long-term morbidity and mortality rates. Using these definitions, from 2011 to 2014, slightly more women than men were designated obese-36 versus 34 percent (Ogden, 2015). Among girls and women, the prevalence of obesity rises with age and varies among ethnicities. Although obesity is now common among all socioeconomic levels, the overall severity advances with increasing poverty (Bilger, 2017). Also, a genetic predisposition has been identified from several gene loci (Locke, 2015; Shungin, 2015). Many fat tissue cells communicate with all other tissues via endocrine and paracrine factors, which are cytokines specifically termed adipocytokines. It enhances insulin sensitivity, blocks hepatic glucose release, and has cardioprotective effects on circulating plasma lipids. An adiponectin deficit is linked with diabetes, hypertension, endothelial cell activation, and cardiovascular disease. Indeed, adipokines, especially the inflammatory cytokines, may be the primary stimulant of insulin resistance (Al-Badri, 2015; Yang, 2016). Conversely, adiponectin has antiinflammatory and insulin-sensitizing roles and is negatively regulated by fat mass. As one example of the discordant effects of these adipokines, gestational diabetes is associated with lower adiponectin but higher leptin levels. Cheap atlacne 20mg online.

By way of comparison skin care ingredients to avoid purchase atlacne on line, about a fourth of the nonpregnant population had indeterminate studies. The investigators attributed this difference to the younger age of the pregnant patients. Intravascular Pulmonary Angiography this requires catheterization of the right side of the heart and is considered the reference test for pulmonary embolism. This is especially true given the higher radiation exposure for the fetus (Konstantinides, 2014; Kuriakose, 2010). Other detractions are that it can be time consuming, uncomfortable, and associated with dye-induced allergy and renal failure. Management Immediate treatment for pulmonary embolism is full anticoagulation similar to that for deep-vein thrombosis as discussed on page 1012. Vena Caval Filters the woman who has very recently suffered a pulmonary embolism and who must undergo cesarean delivery presents a particularly serious problem. Reversal of anticoagulation may be followed by another embolus, and surgery while fully anticoagulated frequently results in life-threatening hemorrhage or troublesome hematomas. In these cases, placement of a vena caval filter should be considered before surgery (Marik, 2008). Moreover, in the very infrequent circumstances in which heparin therapy fails to prevent recurrent pulmonary embolism from the pelvis or legs, or when embolism develops from these sites despite heparin treatment, a vena caval filter may also be indicated. Such filters can also be used following massive emboli in patients who are not candidates for thrombolysis (Deshpande, 2002). The device is inserted through either the jugular or femoral vein and can be inserted during labor (Jamjute, 2006). Routine filter placement has no added advantage to heparin given alone (Decousus, 1998). Retrievable filters may be used as short-term protection and then removed 1 to 2 weeks later (Liu, 2012). From their systematic review, Harris and associates (2016) found that complication rates in pregnant women with vena caval filters are comparable to those in nonpregnant patients. Thrombolysis Compared with heparin, thrombolytic agents provide more rapid lysis of pulmonary clots and improvement of pulmonary hypertension (Tapson, 2008). Konstantinides and coworkers (2002) studied 256 nonpregnant patients receiving heparin for an acute submassive pulmonary embolism. They also were randomly assigned to a placebo or the recombinant tissue plasminogen activator alteplase. Those given the placebo had a threefold greater risk of death or treatment escalation compared with those given alteplase. Agnelli and associates (2002) performed a metaanalysis of trials involving 461 nonpregnant patients. They reported that the risk of recurrence or death was significantly lower in patients given thrombolytic agents and heparin compared with those given heparin alone- 10 versus 17 percent. Importantly, however, there were five-2 percent-fatal bleeding episodes in the thrombolysis group and none in the heparin-only group. In their review, Leonhardt and colleagues (2006) identified 28 reports of tissue plasminogen activator use during pregnancy. Complication rates were similar to those in nonpregnant patients, and the authors concluded that such therapy should not be withheld during pregnancy if indicated. However, Akazawa and Nishida (2017) reviewed 13 cases of systemic thrombolytic therapy administered during the first 48 hours after delivery. Blood transfusion was required in five of the eight cesarean deliveries, including three cases of hysterectomy and two cases of hematoma removal. Embolectomy Given the efficacy of thrombolysis and filters, surgical embolectomy is uncommonly indicated. Published experience with emergency embolectomy during pregnancy is limited to case reports (Colombier, 2015; Saeed, 2014). From their review, Ahearn and associates (2002) found that although the operative risk to the mother is reasonable, the stillbirth rate is 20 to 40 percent. In one review of guidelines for thromboprophylaxis in pregnancy, the authors concluded that there is a lack of overall agreement about which women should be offered thromboprophylaxis or offered testing for thrombophilias (Okoroh, 2012).
