Sex Differences in Heart Failure: What Do We Know?

Heart failure (HF) remains an important global health issue, substantially contributing to morbidity and mortality. According to epidemiological studies, men and women face nearly equivalent lifetime risks for HF. However, their experiences diverge significantly when it comes to HF subtypes: men tend to develop HF with reduced ejection fraction more frequently, whereas women are predominantly affected by HF with preserved ejection fraction. This divergence underlines the presence of numerous sex-based disparities across various facets of HF, encompassing aspects such as risk factors, clinical presentation, underlying pathophysiology, and response to therapy. Despite these apparent discrepancies, our understanding of them is far from complete, with key knowledge gaps still existing. Current guidelines from various professional societies acknowledge the existence of sex-based differences in HF management, yet they are lacking in providing explicit, actionable recommendations tailored to these differences. In this comprehensive review, we delve deeper into these sex-specific differences within the context of HF, critically examining associated definitions, risk factors, and therapeutic strategies. We provide a specific emphasis on aspects exclusive to women, such as the impact of pregnancy-induced hypertension and premature menopause, as these unique factors warrant greater attention in the broader HF discussion. Additionally, we aim to clarify ongoing controversies and knowledge gaps pertaining to the pharmacological treatment of HF and the sex-specific indications for cardiac implantable electronic devices. By shining a light on these issues, we hope to stimulate a more nuanced understanding and promote the development of more sex-responsive approaches in HF management.

PREGNANCY INDUCED HYPERTENSION AND NEONATAL GROWTH

Pregnancy-induced hypertension (PIH), especially preeclampsia, is a major cause of maternal and perinatal morbidity and mortality worldwide. The impact of PIH on birth outcomes has not been extensively studied. PIH has been confirmed to increase significantly the risk of low birth weight by both increasing preterm birth as well as reducing fetal growth. Low birth weight or IUGR babies have been associated with the occurrence of several chronic diseases in later life. However, to date, there have been few studies on the effects of PIH on infant growth and neonatal wellbeing. The purpose of this study was to evaluate the fetal growth and wellbeing of newborns born of mothers with confirmed pregnancy induced hypertension.Material and methods: This was prospective opservational study during the period of the last year, 1st of July 2018 up to the end of June 2019 conducted at the University Clinic for Gynecology and Obstetrics in Skopje. As pregnancy induced hypertension is defined the condition of blood pressure equal to or greater than 130/90 mmHg on more than two occasions greater than six hours apart without proteinuria after 21 weeks of gestation. All other more severe conditions are defined as pre-eclampsia or eclampsia. As outcome was considered the birth weight, gestational age and white blood cells count. IUGR was defined as birth weight below the tenth percentile of expected weight for gestational age. Also maternal age and BMI were considered as conjoined risk factor for the birth weight. Results: In this study, 4726 newborns were born at the University Clinic for Gynecology and Obstetrics, and for analysis were considered 4273 newborns who were late preterm (35 and 36 gestational weeks) or term newborns. Two groups were evaluated: control group of 200 consecutively born newborns (late preterm and term) of healthy mothers and 100 newborns (late preterm and term) consecutively born of mothers with confirmed diagnosis of PIH, which constituted the study group. Within the control group, the proportion of Small for Gestational Age-SGA was 6,3%, and in the group of mothers with PIH was 9,5% (p<0,05). The maternal mean age of the hypertensive mothers was (32.8±5.0) years while that of normotensive mothers was (26.6±3.7) years, and there was not statistical significance (p>0.05). The Body Mass Index was higher in hypertensive mothers, compared to the healthy mothers (31,3±2.02 vs. 27.8±2.8). The mean gestational age of the study group was (35.8±1.8) weeks compared to that in control group (37.4±1.2) weeks. The number of White Blood Cells (WBC) count in newborns of hypertensive mothers was 21.4±5.3x109/L compared with the control group, 18.5±3.12x109/L (p=0.005). Neonatal thrombocytopenia was found in 32% of neonates of preeclamptic mothers while it's found only in 9.5% of neonates in control group p<0,002. Discussion: The limitation of this study was the lack of data about maternal smoking, life style, etc. There is limited number of studies examining the correlation between fetal growth and PIH, and every information is of great value. The fact is that this condition can progress in more severe degree of hypertension and deleterious effects on the mother itself and on her child, if not treated on time. Conclusion: A change in infant growth of the IUGR baby itself (e.g. catch-up growth) such as in the critical early infant period may also have long-term effects on health later in life, and this change of postpartum growth may be influenced by PIH. Therefore, it is important to study postpartum infant growth patterns of babies born to mothers with PIH, and to determine if there are differences in infant growth between babies with and those without IUGR. And, the most important action is to monitor and treat pregnancy induced hypertension and prevent more severe condition of pre-eclampsia.

Impact of pregnancy-induced hypertension on fetal growth

Background: Pregnancy-induced hypertension (PIH) is still a major cause of maternal and infant morbidity and mortality worldwide. The aim of this study to investigate the impact of PIH on fetal growth.Methods: A longitudinal cross-sectional study was conducted by 2,076 obstetric patients registered in the book of delivery emergency room BLUD RSUD Ende/ Ende hospital from September 1st 2014 to August 31st 2015. Pregnancy-induced hypertension was classified into gestational hypertension, preeclampsia, and severe preeclampsia. Categorical comparative chi-square continued by logistic regression analysis were performed to examine the effect of PIH to infants’ growth outcome.Results: Women with preeclampsia had higher number of preterm delivery (26.7%). Infants born from preeclamptic women had lower birth weight (median 2,575 gram; p<0.001), birth length (median 49 cm; p<0.001), and also head circumference (median 32 cm; p<0.001). Severe preeclampsia contributed statistically significance to SGA (OR=1.90; 95% CI=1.20-3.01; adjusted OR=1.91; 95% CI=1.20-3.01) and LGA (OR=2.70; 95% CI=1.00-7.29; adjusted OR=2.92; 95% CI=1.07-8.00). Based on birth weight independent of gestational age, severe preeclampsia had an impact to VLBW (OR=11.45; 95% CI=2.77-47.38; adjusted OR=8.68; 95% CI=1.57-48.04) and LBW (OR=6.57; 95% CI=4.01-10.79; adjusted OR=5.71; 95% CI=3.33-9.78) where it showed statistical significance.Conclusion: PIH women who had SGA or VLBL or LBW infants were caused by the hypoperfusion model as the pathogenesis of preeclampsia. Meanwhile, LGA infants born by preeclamptic women were due to the compensation of the decrease from uteroplacental perfusion or other diseases such as obese mother or gestational.diabetes mellitus.

Impact of Pregnancy-induced Hypertension on Stillbirth and Neonatal Mortality

Hypertensive disorders of pregnancy are more frequent in primiparous women, but may be more severe in multiparas. We examined trends in stillbirth and neonatal mortality related to pregnancy-induced hypertension (PIH), and explored whether mortality varied by parity and maternal race. We carried out a population-based study of 57 million singleton live births and stillbirths (24-46 weeks' gestation) in the United States between 1990 and 2004. We estimated rates and adjusted odds ratios (ORs) of stillbirth and neonatal death in relation to PIH, comparing births in 1990-1991 with 2003-2004. PIH increased from 3.0% in 1990-1991 to 3.8% in 2003-2004. In both periods, PIH was associated with a higher risk of stillbirth and neonatal death. We explored this in more detail in 2003-2004, and observed that the increased risk of PIH-related stillbirth was higher in women having their second or higher-order births (OR = 2.2 [95% confidence interval = 2.1-2.4]) compared with women having their first birth (1.5 [1.4-1.6]). Patterns were similar for neonatal death (1.3 [1.2-1.4] in first and 1.6 [1.5-1.8] in second or higher-order births). Among multiparas, the association between PIH and stillbirth was stronger in black women (2.9 [2.7-3.2]) than white women (2.0 [1.8-2.1]). A substantial burden of stillbirth and neonatal mortality is associated with PIH, especially among multiparous women, which may be due to more severe PIH, or to a higher burden of underlying disease.

819: Impact of pregnancy-induced hypertension on perinatal survival in first and higher order births: A population-based study

Preeclampsia is more frequent in primiparous women; yet, it may be more severe in multiparas. However, patterns of perinatal mortality following pregnancy-induced hypertension (PIH) in primiparas and multiparas have not been extensively studied. We explored differences in perinatal mortality rates based on PIH status and evaluated trends in PIH-related perinatal mortality risks. We further examined whether these risks were influenced by obstetrical interventions, geographic region, and race.

Impact of pregnancy-induced hypertension on fetal growth

Objective: The purpose of this study was to evaluate the effect of different types of pregnancy-induced hypertension on fetal growth. Study Design: A retrospective cohort study was conducted on the basis of 16,936 births from January 1, 1989, through December 31, 1990, by means of data from a population-based perinatal database in Suzhou, China. Pregnancy-induced hypertension was classified as gestational hypertension, preeclampsia, or severe preeclampsia-eclampsia. Univariate and multivariate regression analyses were performed to examine the effect of the various types of pregnancy-induced hypertension on gestational age, preterm birth, birth weight, low birth weight, and intrauterine growth restriction. Results: Gestation was 0.6 week shorter in women with severe preeclampsia than in normotensive women ( P < .01). However, the risk of preterm birth was not increased with any classification of pregnancy-induced hypertension (for severe preeclampsia: adjusted odds ratio 1.75; 95% confidence interval, 0.88-3.47). After adjustment for duration of gestation and other confounders, preeclampsia and severe preeclampsia increased the risk of intrauterine growth restriction and low birth weight. The adjusted odds ratios of low birth weight were 2.65 (1.73-4.39) for preeclampsia and 2.53 (1.19-4.93) for severe preeclampsia. However, the risk of low birth weight was not increased significantly for gestational hypertension (adjusted odds ratio 1.56 [1.00-2.41]). Conclusion: Preeclampsia increases the risk of intrauterine growth restriction and low birth weight. (Am J Obstet Gynecol 1999;180:207-13.)
