Background: Maternal cardiovascular risk and its implications can have significant repercussions for both the mother and the child. This study compares the lipid profiles of two distinct groups of pregnant women, those with and without cardiovascular risk, to shed light on its effects on maternal and outcomes for newborns. Materials and Methods: This study enrolled 86 pregnant women, dividing them into two groups: Group 1 (n = 46, healthy pregnancies) and Group 2 (n = 40, pregnancies with cardiovascular risk factors). The data collected included maternal demographics, smoking history, pre-existing pathologies, and a range of laboratory measures. Neonatal outcomes were also recorded. Results: Group 2 showed a significant increase in the percentage of newborns with abnormal APGAR scores (p-value < 0.0001), congenital abnormalities (p-value < 0.0001), severe prematurity (p-value < 0.0001), and neonatal mortality rates (p-value < 0.0001), as well as differences in birth weight (p-value = 0.0392) and therapy usage (surfactant: p-value < 0.001, steroids p-value = 0.004, and antibiotics p-value < 0.001). Regarding laboratory measures, Group 2 exhibited significantly elevated levels of total cholesterol, LDL-C (p-value < 0.0001), ApoB (p-value < 0.0001), Lp(A) (p-value = 0.0486), triglycerides (p-value < 0.0001), and hs-CRP (p-value = 0.0300). Discussion: These results underscore the elevated risk associated with pregnancies complicated by cardiovascular risk factors. Group 2 demonstrated a more concerning clinical profile, with a higher prevalence of detrimental neonatal outcomes and different lipid and inflammatory profiles, signifying a potential pathophysiological link. Conclusions: The differential lipid profiles and adverse neonatal outcomes in pregnancies with cardiovascular risks highlight the urgency of effective risk stratification and management strategies in this population.
