The reduced blood flow associated with HF triggers the activation of neurohormonal systems, leading to symptoms such as pulmonary congestion and peripheral edema. The precise mechanisms responsible for edema in HF are poorly understood. In this study, we aimed to analyze the differentially expressed proteins in HF-induced pulmonary edema (HF-PE) and explore the potential underlying mechanisms. Proteins in the serum of patients with HF-PE (n = 10) and patients with HF without PE or those who have not developed PE yet (n = 10) were screened using tandem mass tag-labeling proteomics. The identified proteins were screened for differentially expressed proteins, which were then analyzed using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses as well as protein-protein interaction (PPI) visualization. Rats with HF were induced by myocardial infarction, whereas PE was induced by LPS. Finally, the rats were injected with lentiviruses to manipulate the expression of differentially expressed proteins. A total of 1796 proteins were identified. In the serum of patients with HF-PE, there were 143 significantly upregulated proteins and 147 significantly downregulated proteins. TLN1 interacted with multiple proteins and was upregulated in patients with HF-PE. TLN1 was significantly upregulated in the lung tissues of rats with HF-PE, and the progression of HF-PE was inhibited by TLN1 knockdown.

Furthermore, our results showed that the effects of the maternal diet during gestation are profound and normal lactation and feeding after delivery cannot help adult offspring recover from defective heart development.

We present here a case of an elderly patient with an LV pseudoaneurysm that developed over a long period of time after Dor operation. An 83-year-old man with rapid LV enlargement 18 years after Dor operation presented with dyspnea. We diagnosed his mass as an LV pseudoaneurysm using multiple non-invasive imaging modalities. The suture between the patch and the LV myocardium became fragile and detached over time. However, due to adhesion in the thorax and slow blood flow, the enlargement stopped. Surgery was considered, but due to his age and renal dysfunction, he did not undergo surgery. Conservative treatment with antihypertensive and heart failure therapy was continued. Clinical manifestations of LV pseudoaneurysm vary from asymptomatic to signs of heart failure and even sudden death. Surgery is recommended for LV pseudoaneurysm because of the high risk of rupture, but conservative treatment may be an option that has been developed long after surgery in the era of an increasing number of elderly OMI or post-cardiac surgery patients.
