Early Evaluation of Exosome Multiomics and Clinical Prognosis in Patients With Sudden Death

Acute coronary syndrome (ACS) is one of the main causes of death. Worldwide, tens of millions of patients are hospitalized for coronary heart disease and ACS every year. ACS may show acute myocardial infarction, unstable angina pectoris, and even induce early arrhythmia, leading to sudden death. Sudden cardiac death (SCD) has a strong correlation with ACS. Data from clinical and autopsy studies and death certificates show that 62-85% of patients with out of hospital SCD have a history of ACS, 10% have other cardiac structural abnormalities, and 5% have no cardiac structural abnormalities. An SCD surveillance study from Ireland concluded that most cases occurred in families, and the successful recovery of SCD was mainly related to ventricular fibrillation with arrhythmia. At present, there are few reports on the clinical and prognosis of ACS in China, and there is no guideline or consensus on the prevention and treatment of ACS patients. Known domestic research results show that the proportion of male, overweight / obese, smokers in young ACS patients is higher than that in the elderly group, while the proportion of patients with hypertension, diabetes and cerebrovascular diseases is less than that of the elderly group. The levels of TC, TG, LDL-C and UA and the proportion of low HDL-C in young ACS patients were higher than those in elderly patients; The diagnosis of STEMI was the highest in the young ACS group, while the diagnosis of unstable angina pectoris was the most common in the elderly ACS group. The clinical manifestations of ACS vary greatly. 3% \~ 5% of patients who exclude ACS only through myocardial markers, clinical blood transfusion and ECG still have myocardial infarction (MI). For the emergency department, early prediction of the risk of SCD in ACS patients and timely and accurate screening of high-risk patients are very important.

MSC Exosome Therapy for Post-Preeclampsia Endothelial Dysfunction

\--- Why Is This Study Being Done? Women who have preeclampsia during pregnancy face a much higher risk of heart disease later in life. Preeclampsia is a serious pregnancy condition that causes high blood pressure and damages blood vessels. Even after the baby is born, the blood vessels do not fully heal on their own, which can lead to heart problems/cardiovascular years later. This study tests whether a new treatment called exosomes can help repair damaged blood vessels in women who had preeclampsia. Exosomes are tiny particles that come from stem cells and contain healing substances that may help blood vessels work better. \--- What Will Happen in This Study? This study will include 80 women who recently gave birth and had preeclampsia during their pregnancy. Half of the women will receive the exosome treatment through an IV, and half will receive a placebo (a substance with no active treatment). \--- What Will Participants Need to Do? Participants will: * Have blood tests and other health checks * Receive one treatment through an IV * Return for follow-up visits at 1 week after treatment * Have tests to check how well their blood vessels are working Who Can Join This Study? Women who: * Recently gave birth (within 1-2 weeks) * Had preeclampsia during their last pregnancy * Are healthy enough to participate * Can give permission to join the study What Are the Possible Benefits and Risks? The treatment may help repair blood vessel damage and reduce the risk of future heart disease. The exosome treatment appears to be safe based on other studies, but like any medical treatment, there may be side effects. \--- How Long Will the Study Last? The main treatment happens during one visit, with follow-up visits for 1 week to check on participants' health and see if the treatment is working. This research may lead to new ways to protect women's heart health after pregnancy complications.
