There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The goal of this observational study is to learn about the influencing factors of chronic heart failure prognosis in heart failure patients. The main question it aims to answer is that what are the influencing factors of clinical outcomes in chronic heart failure. Participants will be collected multiple omics data such as phenotype group, environmental exposure group, intestinal microbiome, genome, metabolome, and noninvasive biomarkers.
The increased risk of Atrial fibrillation (AF) regarding thromboembolic stroke is predominantly due to the formation and embolization of clots from within the left atrial appendage (LAA). Percutaneous left atrial appendage occlusion (LAAO) is a nonpharmacological strategy for stroke prevention in patients with AF. Data from randomized trials, including PROTECT-AF, PREVAIL, and Prague-17, have suggested that LAAO has comparable efficacy to warfarin or NOACs. Considering these results, LAAO was recommended by the American College of Cardiology (ACC) and European Society of Cardiology (ESC) guidelines as a non-pharmacological stroke prevention strategy for patients with NVAF who have contraindications or are unsuitable for OAC. The PROTECT-AF and PREVAIL trials stipulated the use of standardized antithrombotic medications which were designed to minimize the risk of stroke, systemic embolism, or device-related thrombosis. This antithrombotic strategy was subsequently endorsed by the guidelines, briefly, patients with LAAO were discharged on warfarin and aspirin for 45 days post-LAAO, if there was no leak or a leak ≤5 mm under transesophageal echocardiography (TEE) at 45-day follow-up, antithrombotic strategies shall switch to dual antiplatelet therapy (DAPT) until 6 months post-LAAO, and then aspirin thereafter. Although LAAO was recommended by medical societies, previous patient-level meta-analyses have implied that compared with oral anticoagulation, LAAO had significantly more ischemic strokes, suggesting the inability of LAAO to prevent an ischemic stroke from sources beyond LAA. Will a combined strategy of LAAO and OAC further reduce the risk of stroke? The investigators hypothesized that a long-term low dose-Rivaroxaban (10mg daily) post-LAAO might be a potent supplement to the residue risk of ischemic stroke.
Empagliflozin Treatment of GSD-1b patients
We initiate this study to assess the diagnostic efficiency of PReTEE, a simplified TEE scan sequence with a combination of 3 valuable views of ME 4C, ME AV LAX and TG SAX, in identifying cardiac pathologies in the phase of difficult cardiopulmonary bypass separation among patients who will undergo high-risk cardiac surgical procedures.
The purpose of this study is to assess what macitentan and its active metabolite (aprocitentan) does to the body after single dose administration of macitentan in Chinese healthy adult male participants.
Aims to evaluation the LC-MS/MS-specific cutoffs of PA screening and CCT test.
This is a phase Ib/II clinical trial to evaluate the safety and efficacy of TQB3909 tablets in patients with recurrent or refractory CLL/SLL.
The primary aim of phase II CEIL study is to evaluate the efficacy of cetuximab and envafolimab plus mFOLFOXIRI versus cetuximab plus mFOLFOX6/FOLFIRI as first line treatment of patients with initially unresectable and previously untreated RAS/BRAF wild-type, MSS, left-side metastatic colorectal cancer(mCRC), in terms of Progression-free Survival.
The purpose of this study is to establish the large PH cohort and biological database in China, aiming for precision medicine to optimize diagnosis and treatment choices.
Untreated patients with Nodal T-follicular Helper (TFH) Cell Lymphoma will be treated with chidamide combined with azacitidine for four cycles. For patients with interim evaluation of CR, consolidation therapy with ASCT or another eight cycles with chidamide combined with azacitidine can be obtained. For patients with interim evaluation of PR, another two cycles of chidamide combined with azacitidine will be continued, followed by the second efficacy evaluation, and those who achieve CR receive consolidation therapy with ASCT or another six cycles of chidamide combined with azacitidine. Subsequently, chidamide was given as maintenance therapy for 12 months. Patients with SD or PD withdrew from this study.
