利用凝结时间、抗压强度等测试，系统评价了水化硅酸钙（C-S-H）晶种与硫酸铝（AS）对硅酸盐-硫铝酸盐复合胶凝体系（PC-CSA）凝结硬化性能的影响，并通过水化进程、水化产物和微观结构分析探究其内在作用机理.结果表明：C-S-H晶种与AS均能显著缩短PC-CSA的凝结时间；复掺C-S-H晶种与AS显著促进了PC-CSA中硅相矿物的水化，提高了微观结构的致密性，提升了PC-CSA的抗压强度；当单掺AS时，PC-CSA中水化产物C-S-H的成核与长大过程均受抑制，而C-S-H晶种的加入通过提供成核位点，减缓了对水化产物C-S-H成核过程的抑制效果，促进了硅相矿物的反应，有助于解决喷射混凝土速凝与早强不协调的问题.

Left Ventricular End-Diastolic Dimension as an Outcome After Combined Mitral Valve Surgery and CABG

引用

World Journal of Cardiovascular Surgery 2025年第1期15卷 12-21页

作者： Walid Hammad Aboubakr hasan Mansour Mohamed Elsayed Moussa Ashraf Ibrahim Zahra Sherif S. Eliwa Cardiothoracic Surgery Department Al-Azhar Faculty of Medicine Al-Azhar University Cairo Egypt Children of Egypt Abulreesh Hospital General Authority for Health Insurance Ministry of Health Cairo Egypt Cardiothoracic Surgery Department Shebin El Kom Teaching Hospital Shebin al-Kom Egypt

Background: Left ventricular size is a factor independently associated with increased mortality in mitral surgery, particularly, in the setting of ischemic mitral regurgitation (IMR). In some patients with dilated ventricles, reverse remodelling does not occur, with a high risk of residual or recurrent mitral regurgitation and therefore associated with worse outcome. We conducted multi-centers retrospective observational study on a cohort of patients who had combined CABG and mitral surgery for moderately severe IMR to correlate a relationship between perioperative left ventricular dimensions to postoperative mortality rates in both genders. Results: 287 patients had combined CABG and mitral valve surgery. The exclusion criteria were patients with very low function Conclusion: Failure of early ventricular remodeling with persistently elevated end systolic dimensions is a risk factor for postoperative death in both genders. Females gender will have an additional higher risk if the end diastolic dimensions remain elevated.
