Is There a Relationship between Adverse Pregnancy Outcomes and Future Development of Atherosclerosis?

Exercise Intervention to Mitigate the Cardiovascular Sequence of Pregnancy Complications

Pregnancy issues such as gestational hypertension, preeclampsia, and gestational diabetes mellitus (GDM) are significant contributors to long-term cardiovascular diseases (CVDs) in women. Recent research has proved the impact of exercise on improving cardiovascular outcomes, particularly in women with pregnancy-related disorders. This review explores the outcomes of various exercise interventions on cardiovascular health in pregnant women. Among these, aerobic exercise has been widely studied, with results from observational studies and randomized controlled trials (RCTs) showing its positive outcomes on cardiovascular health in pregnant women, especially with complications. It has been found that regular aerobic exercise has been associated with reduced hypertension and improved endothelial function, particularly in women with a history of preeclampsia. Evidently, aerobic exercise results in better blood pressure regulation and enhanced vascular health that directly attends to the risk of cardiovascular diseases associated with pregnancy complications. Another form of exercise is resistance training, which despite being studied less, has shown potential benefits as well. Some advantages of resistance exercise have been found to improve muscle strength and overall enhancement in metabolic control. This is important, especially in women with GDM whereby improvement in insulin sensitivity reduces the overall risk of type 2 diabetes and future CVDs. Combined exercise that incorporates both aerobic and resistance elements has been known to offer the most comprehensive benefits. Various studies suggest that a combinatory approach maximizes the positive cardiovascular effects. Practicing women have experienced better overall heart health, with improved blood pressure regulation, enhanced endothelial function, and reduced metabolic risks. However, despite these findings, there are challenges such as small sample sizes and limited follow-up durations that hinder the generalizability of current research. Importantly, previous studies targeting exercise interventions for women experiencing complications during pregnancy have been limited in evidence by small sample sizes, short follow-ups, and lack of diversity. Such broader, more diverse populations were needed to reflect the various health risks and responses to exercise. Future research must include multi-center RCTs, diverse exercise regimens, and digital health tools for monitoring exercise adherence. This warrants future large-scale, multicenter trials that are necessary to establish more definitive evidence. Additionally, clinicians should consider including tailored exercise programs in care plans for women with pregnancy complications to mitigate long-term cardiovascular risks.

Evaluating Maternal Risk Factors Impacting Fetal Intima-Media Thickness of the Abdominal Aorta Measured at 28 Weeks of Gestation

Background and Objectives: Cardiovascular disease risk can exist in utero, influenced by maternal health factors. This study evaluates maternal characteristics and biochemical markers that correlate with the fetal intima-media thickness (IMT), aiming to identify interventions that could minimize prenatal influences on later cardiovascular disease. Methods: In this observational study approved by the Institutional Review Board at The Obstetrics and Gynecology Clinic of the Timisoara Municipal Emergency Hospital, we recruited pregnant women aged 15-40 years, divided into groups based on their lipid profiles and gestational diabetes risk. The data collection had, as its main focus, ultrasound measurements, along with demographic, clinical, and biochemical parameters. The IMT of the fetal abdominal aorta was measured at 28 weeks of gestation. Results: Notable differences were observed in the TNF-alpha levels (8.66 ± 3.87 pg/mL vs. 4.96 ± 3.37 pg/mL), hsCRP levels (0.94 ± 0.46 mg/L vs. 0.60 ± 0.52 mg/L), and the area under the curve (AUC) for hsCRP at 0.738 with a sensitivity of 84.41% and specificity of 79.01%. Compound score 2, integrating inflammatory markers and lipid profiles, exhibited a good diagnostic accuracy (AUC = 0.789) with a sensitivity of 86.35% and specificity of 81.42%. A regression analysis indicated strong associations of TNF-alpha and hsCRP with an increased fetal IMT, suggesting potential early markers of cardiovascular risk, presenting hazard ratios (HRs) of 2.21 (95% CI: 1.15-5.28) and 2.87 (95% CI: 1.11-4.23), respectively, both with p-values of less than 0.0001. Compound score 2 further indicated an increased risk (HR = 4.27; 95% CI: 1.19-8.32). Conclusions: Statistically significant correlations were found between an increased fetal IMT and elevated maternal inflammatory markers (TNF-alpha and hsCRP), suggesting that these could serve as early indicators of cardiovascular risk. This study supports the potential for targeted prenatal interventions to reduce cardiovascular risk factors from the fetal stage, emphasizing the importance of monitoring inflammatory markers in pregnant women at risk.

Association of cardiovascular risk factors and myocardial hypertrophy in women with preeclampsia history

AIMS

A historic of preeclampsia (PE) has been associated with cardiovascular disease (CVD) in women. There are substantial evidences that cardiovascular changes resulting from PE can persist even after pregnancy end. Therefore, the aims was to evaluate the prevalence of myocardial hypertrophy in young women 12 months after PE event as well as try to identify risk factors for these changes.

MATERIALS AND METHODS

Single-center observational prospective cross-sectional study that included 118 consecutive patients after 12 months of PE. Clinical and laboratory evaluations, echocardiogram were performed. Myocardial hypertrophy (LVH) was defined as an index myocardial mass ≥ 45 g/m2.7, for women. Classical risk factors for CVD were considered. Analysis included linear or logistic regression and Spearman's correlation coefficient. Significance level of 5 %.

KEY FINDINGS

Systemic arterial hypertension (SAH) was identified in 52 patients (44 %), overweight/obesity (OOB) in 82 (69 %), dyslipidemia in 68 (57 %) and metabolic syndrome in 47 patients (40 %). LVH was present in 35 cases (29 %) and associated with OOB (OR = 4.51; CI95%:1.18-17.17, p < 0.001), in a model corrected for age and SAH diagnosis. When only the metabolic syndrome components were analyzed, in the multiple logistic regression model, the abdominal circumference was the only clinical variable associated with LVH (OR = 17.65; CI95%:3.70-84.17; p < 0.001).

SIGNIFICANCE

It was observed a high prevalence of ventricular hypertrophy in young women with a history of pre-eclampsia. This condition was associated with the presence of obesity.
