Connecting the Dots: Exploring the Interplay Between Preeclampsia and Peripartum Cardiomyopathy.

ABSTRACT: Preeclampsia and peripartum cardiomyopathy (PPCM) are significant obstetric problems that can arise during or after pregnancy. Both are known to be causes of maternal mortality and morbidity. Several recent studies have suggested a link between preeclampsia and the pathophysiology of PPCM. However, the common thread that connects the two has yet to be thoroughly and fully articulated. Here, we investigate the complex dynamics of preeclampsia and PPCM in this review. Our analysis focuses mainly on inflammatory and immunological responses, endothelial dysfunction as a shared pathway, and potential genetic predisposition to both diseases. To begin, we will look at how excessive inflammatory and immunological responses can lead to clinical symptoms of both illnesses, emphasizing the role of proinflammatory cytokines and immune cells in modifying vascular and tissue responses. Second, we consider endothelial dysfunction to be a crucial point at which endothelial damage and activation contribute to pathogenesis through increased vascular permeability, vascular dysfunction, and thrombus formation. Finally, we examine recent information suggesting genetic predispositions to preeclampsia and PPCM, such as genetic variants in genes involved in the management of blood pressure, the inflammatory response, and heart structural integrity. With this synergistic study, we seek to encourage more research and creative therapy solutions by emphasizing the need for an interdisciplinary approach to understanding and managing the connection between preeclampsia and PPCM.

Project description:BackgroundPregnancy imposes significant cardiovascular adaptations, including progressive increases in plasma volume and cardiac output. For most women, this physiological adaptation resolves at the end of pregnancy, but some women develop pathological dilatation and ultimately heart failure late in pregnancy or in the postpartum period, manifesting as peripartum cardiomyopathy (PPCM). Despite the mortality risk of this form of heart failure, the molecular mechanisms underlying PPCM have not been extensively examined in human hearts.MethodsProtein and metabolite profiles from left ventricular tissue of end-stage PPCM patients (N=6-7) were compared with dilated cardiomyopathy (DCM; N=5-6) and nonfailing donors (N=7-18) using unbiased quantitative mass spectrometry. All samples were derived from the Sydney Heart Bank. Data are available via ProteomeXchange with identifier PXD055986. Differential protein expression and metabolite abundance and Kyoto Encyclopedia of Genes and Genomes pathway analyses were performed.ResultsProteomic analysis identified 2 proteins, SBSPON (somatomedin B and thrombospondin type 1 domain-containing protein precursor) and TNS3 (tensin 3), that were uniquely downregulated in PPCM. SBSPON, an extracellular matrix protein, and TNS3, involved in actin remodeling and cell signaling, may contribute to impaired tissue remodeling and fibrosis in PPCM. Metabolomic analysis revealed elevated levels of homogentisate and deoxycholate and reduced levels of lactate and alanine in PPCM, indicating disrupted metabolic pathways and glucose utilization. Both PPCM and DCM shared pathways related to inflammation, immune responses, and signal transduction. However, thyroid hormone signaling was notably reduced in PPCM, affecting contractility and calcium handling through altered expression of PLN (phospholamban) and Sarcoendoplasmic Reticulum Calcium ATPase (SERCA). Enhanced endoplasmic reticulum stress and altered endocytosis pathways in PPCM suggested additional mechanisms of energy metabolism disruption.ConclusionsThe present study reveals unique posttranslational molecular features of the PPCM myocardium, which mediates cellular and metabolic remodeling, and holds promise as potential targets for therapeutic intervention.
