Background: The treatment strategy of early nutritional support after cardiac surgery has gradually been adopted. However, there are no scientific guidelines for the timing and specific programs of early nutritional support. Methods: A retrospective, single-center analysis (2021–2023) was carried out including elderly patients who were admitted for valvular heart disease and received open-heart valve replacement surgery. We designated patients who started the optimized nutritional support after surgery as the optimized enteral nutritional support strategy TN (EN) group and those who received traditional nutritional support as the traditional nutritional support strategy (TN) group. The nutritional and immune indexes, postoperative complications, length of hospital stay, and hospitalization cost of the two groups were compared and analyzed. Results: We identified 378 eligible patients, comprising 193 (51%) patients in the EN group and 185 (49%) patients in the TN group. There was no significant difference in hospital mortality between the two groups, but the proportion of nosocomial pneumonia was significantly lower in the EN group than in the TN group (P < 0.001). In the Poisson regression analysis, EN was not associated with an increase in gastrointestinal complications (P = 0.549). The EN group also seemed to have shorter hospital stays and lower hospitalization expenses (P < 0.001). In the comparison of postoperative gastrointestinal complications, fewer patients experienced diarrhea (P = 0.021) and abdominal distension (P = 0.033) in the EN group compared with the TN group. Conclusion: The optimal nutritional support strategy could effectively improve the clinical outcome of high-risk patients with valvular heart disease.

Background: Most Marfan syndrome (MFS) patients have thoracic aortic diseases which is the major cause of death. The aim of the study is to analyze the impact of different surgical procedures on prognosis of MFS patients. Methods: We retrospectively analyzed the results of hospitalization and long-term follow-up of MFS patients who underwent surgical intervention in our center. Results: Of the 135 MFS patients, 11 died during hospitalization (8.1%). There were no statistical differences in in-hospital mortality between the proximal surgery group and the distal surgery group (P=0.11). Compared to patients who underwent proximal aortic surgery, patients who underwent arch and distal surgery were more likely to have postoperative respiratory dysfunction (P=0.008). The type of surgical procedure was not associated with the incidence of complications during hospitalization. Pre-surgical New York Heart Association (NYHA) Functional Classification IV (P=0.047), EF Conclusions: The David procedure was the most beneficial and had the highest long-term patient survival rates.
