Impact of Assessment and Management of Comorbidities in Internal Medicine on Cardiovascular Risk

The aim of assessing and managing cardiovascular risk is to avoid, limit or delay cardiovascular morbidity and mortality. Planned internal medicine hospitalization is developed around the management of cardiovascular risk in patients at high cardiovascular risk, whether in primary prevention or secondary prevention. During planned hospitalization, patients benefit from comprehensive, personalized and adapted care for their comorbidities and their CVRF (cardiovascular risk factors). This study will make it possible to evaluate this overall course of multidisciplinary management of comorbidities of patients at high cardiovascular risk.

TTE Improves Clinical Management of Stable Chest Pain

The investigator aims to prospectively enroll patients who were referred for transthorcic echocardiography (TTE) for the assessment of stable chest pain (SCP) suspected of obstructive coronary artery disease (CAD). All patients underwent TTE according to established guidelines and local institutional protocols. This study will determine if TTE-based imaging evaluation can provide more informaton to improve clinical management for SCP, including fewer MACE and better decision-making of downstream investigations and therapeutic interventions.

Low-dose Versus Standard-dose Rivaroxaban in Elderly Patients With Atrial Fibrillation

To evaluate the efficacy and safety of low-dose versus standard-dose rivaroxaban anticoagulation therapy in elderly patients with atrial fibrillation.

Study on the Serum Metabolic Markers and Early Complications After Allo-HSCT： Cohort Study

This study aims to establish a cohort of 500 patients with hematological disease who undergoing allogeneic hematopoietic stem cell transplantation in the northwest region. All patients will be followed up at the outpatient clinic once a week after transplantation until 100 days after transplantation to observe the presence of acute graft versus host disease, acute kidney damage, and major cardiovascular adverse events. Serum samples from the day before pre-treatment, day after pre-treatment, 2 weeks，4 weeks，8 weeks and 12 weeks after transplantation will be detected by metabolomics sequencing.The primary objective is to explore the serum metabolic markers of acute graft versus host disease，acute kidney injury, and major adverse cardiac events within 100 days after transplantation，the secondary objective is to observe the high-risk factors for early complications.

Novel Cardiovascular Biomarkers in Patients With Kidney Disease

Chronic kidney disease (CKD) is a long-term condition where the kidneys do not work as well as they should. End-stage kidney failure (ESKD) is the final, irreparable stage of chronic kidney disease (CKD), where kidney function has worsened, so the kidneys can no longer function independently. At this stage, dialysis is required to remove waste products and excess fluid from the blood. There are two types of dialysis. In haemodialysis (HD), blood is pumped out of the body to an artificial kidney machine and returned to the body by tubes that connect a person to the machine. In peritoneal dialysis (PD), the inside lining of the belly acts as a natural filter. PD has the advantage of being gentler on the heart. HD causes significant stress to the heart by reducing the blood flow to the heart muscle, resulting in heart failure, irregular rhythms, and eventually sudden heart death. A large observational study showed that HD patients had 48% worse survival in the first two years than PD patients. Several molecules ('biomarkers') can be detected in blood and inform doctors of heart damage. Studying the form and function of proteins (Proteomics), including how they work and interact with each other inside cells in patients, could help identify the onset of heart problems. HD patients are also prone to body fat changes (cholesterol/lipids). Due to high cholesterol, there is build-up on the walls of arteries, causing their hardening. In HD patients, this process is faster due to abnormalities in lipid structure. Therefore, studying the heart biomarkers, protein, and lipid makeup of HD patients may help to find people at substantial risk of heart and vascular problems and if they are likely to become unwell due to these heart problems.
